The full Guide

Figures are for tax year 2026, as they stand on 25 September 2026. They come from the California Department of Tax and Fee Administration (CDTFA) at cdtfa.ca.gov, the Revenue and Taxation Code (R&TC) on leginfo.legislature.ca.gov, and the Franchise Tax Board (FTB) at ftb.ca.gov. The statewide base rate has been the same since 1 January 2017, so the core rules are the same for 2025 and 2026. A short section at the end covers 2025 periods and 2025 income tax returns.

Scope and who this is for

  • Businesses selling goods in California or shipping to California customers: permits, rates, filing.
  • Out-of-state and marketplace sellers testing California's economic nexus rule.
  • Businesses and individuals who owe use tax, and sellers handling resale certificates (CDTFA-230).
  • Out of scope: vehicles, vessels and aircraft; cannabis, fuel, tobacco and other special taxes and fees; construction contracts; leasing; local taxes that are not sales and use taxes.

Ask the client first

  • Does the business have anything in California: an office, agents who sell, deliver or install, a warehouse, fulfillment-center inventory, leased equipment or a server?
  • If it is outside California: what were its sales of goods for delivery into California in 2025 and so far in 2026, adding related companies and marketplace sales? The test is more than $500,000 (CDTFA Wayfair guide).
  • Does it sell through a registered marketplace, directly, or both?
  • Which permit or registration does it hold, and which filing frequency has CDTFA assigned?
  • What does it sell: goods, food, drinks, supplements, software on media or by download, custom or hosted software, digital downloads, repairs, fabrication?
  • How does each customer receive the goods (counter, common carrier, own truck), and in which city and county?
  • Does it hold a timely resale certificate from each business buyer?
  • Did it use anything in California without paying California tax, including goods from resale stock?
  • Has CDTFA written to require prepayments? Were any returns or payments late?

The method, step by step

  1. Decide whether the business must register. A business that sells goods in California needs a seller's permit for each place of business where it negotiates sales (Regulation 1699). A business outside California must register and collect use tax if it has a physical presence here or if its combined sales of goods for delivery into California, with related persons, exceed $500,000 in the current or preceding calendar year (CDTFA Wayfair guide).
  2. Classify each sale. Sales tax applies to retail sales of tangible personal property unless an exemption applies. Services are not taxed unless they are part of a sale of property (CDTFA Wayfair FAQ). Check food, software and digital products, repair and fabrication, resale and other exemptions in the tables below.
  3. Find the rate for the place of sale or delivery. The base rate is 7.25% everywhere (CDTFA district taxes). Add district tax where the sale takes place, or where the goods are delivered if the seller is engaged in business in that district. Use CDTFA's address lookup for the transaction date: CDTFA rates.
  4. Keep proof (certificates, marketplace and delivery records) for at least four years, and accrue use tax on untaxed goods you use, including goods taken from resale stock.
  5. File by the due date for your assigned frequency, even with no sales, allocating local and district tax on the return schedules, and prepay if CDTFA has told you to (CDTFA filing dates).

Rates for 2026

The statewide base rate (CDTFA detailed description of the rate)

ComponentRateWhere it goes
State3.6875%State General Fund
State0.25%State General Fund
State0.50%Local Public Safety Fund
State0.50%Local Revenue Fund (1991 realignment)
State1.0625%Local Revenue Fund 2011
Local (Bradley-Burns)0.25%County transportation funds
Local (Bradley-Burns)1.00%City or county operations
Total statewide base rate7.25%
  • The state share is 6.00% and the local share is 1.25%, in effect from 1 January 2017 to date (CDTFA rate history).
  • The same rates apply to sales tax and use tax. The rates printed on the return differ from these components because of a 2004 funding change; use the return's rates.

District taxes (CDTFA detailed description of the rate; CDTFA district taxes)

  • Cities, counties and other districts add voter-approved district taxes. Each district tax is between 0.10% and 2.00%, and more than one can apply at one address.
  • Do not keep a list of local rates; they change. Look up the rate for the exact address and date: CDTFA rates (it also links to the address map).
  • A city or county whose total rate is above 7.25% is in a district (Publication 105). Unincorporated areas use the county rate.

Who must register

Seller's permit (Regulation 1699; Publication 107)

  • Who needs one. A person in the business of selling taxable goods needs a permit for each California place of business where sales are customarily negotiated, even a sales office with no stock.
  • Warehouses. A storage-only warehouse supporting a permitted location needs no extra permit. Anyone holding stock in California for sale needs at least one permit, and a warehouse fulfilling sales negotiated out of state needs its own.
  • Temporary sellers. Selling in California even temporarily generally needs a permit.
  • Occasional sales. A person not otherwise required to hold a permit who makes no more than two sales in a 12-month period generally does not need one. A third sale in 12 months, or selling on a business scale, changes that.
  • Not needed. A seller whose sales are all in interstate or foreign commerce, with no sales in California, needs no seller's permit but may need a use tax account.

Out-of-state sellers: physical presence and economic nexus (CDTFA Wayfair guide; CDTFA Wayfair FAQ)

  • Physical presence. A retailer is engaged in business in California, and must register, if it has an office, warehouse or other place of business here, representatives who sell, take orders, deliver or install here, leased property here, or inventory here (including in a fulfillment center).
  • Economic nexus, the test. From 1 April 2019, a retailer must register with CDTFA and collect California use tax if, "during the preceding or current calendar year, the total combined sales of tangible personal property for delivery in California by the retailer and all persons related to the retailer exceed $500,000."
    • More than, not at least. Sales of exactly $500,000 do not meet the test.
    • Either year. Test 2025 and 2026 separately. Crossing in either year is enough.
    • Related persons. Add the sales of every person related to the retailer under Internal Revenue Code section 267(b).
    • What counts. Total sales of goods for delivery in California, which "may include nontaxable sales, such as sales for resale". Marketplace sales count too (see the next section). Services and electronically delivered products are not sales of tangible personal property.
    • No transaction count. California has no 200-transaction test.
  • When collection starts. A seller who crosses $500,000 during the year must register and collect from the next sale. The sale that takes it over the line is not one it must collect on. In CDTFA's example, a seller reached $500,200 on 7 July 2019 and was not liable for use tax on sales before 7 July 2019, "including the $400 transaction that put you over the $500,000 threshold."
  • District use tax. A retailer over the threshold is engaged in business in every district and must collect district use tax on all taxable sales delivered into any district (CDTFA district taxes). The district test counts sales "in this state or for delivery in the state" (R&TC section 7262), so over-the-counter California sales count for a California retailer. The obligation lasts "at least, through the end of the next calendar year".
  • Wholesale only. A distributor making only sales for resale into California need not register. Once over $500,000 with any retail sale, it must.

Marketplace facilitators and marketplace sellers (CDTFA Marketplace Facilitator Act guide; R&TC section 6041)

  • Facilitator. From 1 October 2019, a marketplace facilitator that is registered or required to be registered is the retailer for sales it facilitates, and generally pays the sales tax or collects the use tax on them. It counts those sales as its own when deciding whether it must register. A facilitator contracts with sellers to facilitate their sales for consideration, and both runs the marketplace (for example transmits offers or owns the platform) and provides at least one listed service such as payment processing, fulfillment, listing, pricing, order taking or customer service.
  • Seller, threshold. Unlike some states, California makes a marketplace seller include its facilitated sales when testing the $500,000 threshold.
  • Seller, registration. A marketplace seller does not need to register if all its retail sales are facilitated by a registered facilitator. It must register if it makes any direct sales to California customers (for example on its own website) and is engaged in business here through physical presence or economic nexus.
  • Seller, reporting. A registered marketplace seller reports all its sales, including facilitated ones, and deducts the facilitated sales as "other" on the return. It should keep proof that the facilitator is registered and collecting, such as the facilitator's permit number.
  • Relief. CDTFA will not hold a marketplace seller liable on a facilitated sale if CDTFA can verify that the facilitator collected and paid the correct tax.

What is taxable: boundary and exception table

General rule and services (CDTFA Wayfair FAQ; Regulation 1501)

ItemTreatmentCondition that decides it

Goods shipped out of CaliforniaExemptOnly if the contract of sale requires shipment to a point outside California and the retailer ships it, in its own vehicles or by delivery to a carrier, customs broker or forwarding agent (even one hired by the buyer). Customer pickup in California does not qualify (R&TC section 6396)
Sales to the United States, its unincorporated agencies and instrumentalities, and the American National Red CrossExemptR&TC section 6381
Farm equipment and machinery used primarily to produce and harvest agricultural productsPartly exemptBuyer must be a qualified person (SIC codes 0111 to 0291, or someone assisting them). Local and district taxes and certain state components still apply (R&TC section 6356.5)

Repair, installation and fabrication (Regulation 1546; Regulation 1526)

ItemTreatmentCondition
Installation labor for goods soldNot taxableDoes not cover fabrication of property in place
Repair laborNot taxable
Parts in a repair jobRepairer is the retailer and charges tax on the partsIf the retail value of parts is more than 10% of the total charge, or the parts are charged separately; the repairer must then show parts separately on the invoice
Parts in a repair jobRepairer is the consumer and pays tax on its purchase of the partsIf parts are 10% or less of the total charge and not charged separately
Fabrication, processing or printing on the customer's own materialsTaxableAny operation that creates new tangible property, or is a step in doing so

Food and drink (Regulation 1602; Regulation 1603)

ItemTreatmentCondition
Food products (groceries, bakery goods, snacks)ExemptUnless sold as hot prepared food (but see the hot bakery and hot drink exception below), as a meal, or for eating at the seller's facilities
Candy, confectionery, chewing gumExemptThey are food products
Fruit and vegetable juices; noncarbonated, noneffervescent bottled waterExempt
Carbonated drinks, carbonated or effervescent water, beer, wine and spiritsTaxableNot food products
IceTaxableNot a food product
Dietary and food supplements (vitamin pills, protein supplements)TaxableLabelled as a supplement or designed to add vitamins, proteins, minerals or calories; exempt only as prescription medicine or a complete dietary food
Hot prepared foodTaxableSold hotter than the room; a single price for a meal with any hot item is taxable in full
Hot bakery goods and hot drinks such as coffee, sold for a separate priceExemptUnless taxable under Regulation 1603(b), (c), (d) or (f) (meals, the 80-80 rule, admission places, seller's facilities). A hot drink sold with a bakery item or cold food for a single price is taxable
Meals and food served for eating at the seller's tables, at restaurants, or inside places charging admissionTaxableRegulation 1603(a), (d), (f)
Cold food "to go" from a restaurant-type sellerTaxable only under the 80-80 ruleBoth: more than 80% of gross receipts are from food, and more than 80% of retail food sales are taxable; the food must also be suitable for eating on the premises. The seller may elect to account separately and exempt these sales

Software, hosted software and digital products (Regulation 1502; CDTFA Wayfair general information)

ItemTreatmentCondition
Prewritten (canned) program on storage media (disk, USB drive)TaxableTax applies to the entire amount, including licence fees
Prewritten program transferred electronicallyNot taxableOnly if the buyer does not obtain any tangible property, such as storage media, in the transaction
Custom programNot taxableIn any form, except a basic operational program; separately stated custom changes to a prewritten program are also not taxable
Digital music, video, books and other digital products delivered electronicallyNot taxableOnly if no tangible storage media is transferred
Hosted software (SaaS) used remotelyNot a sale of tangible propertyCDTFA has no SaaS-specific regulation; the basis is that no program copy or media is transferred. If anything is downloaded or shipped, apply the rows above. Get written advice for large contracts

Mixed tangible and intangible sales. Three rules decide most cases:

  • Software and media. A transfer of storage media makes a prewritten program taxable on the whole charge (Regulation 1502). To keep a download non-taxable, the seller must not also hand over a disk or drive.
  • Technology transfer agreements. When a written patent or copyright licence to reproduce and sell, or to make and sell, comes with tangible property, tax applies only to the property. Use its separately stated fair price; otherwise its prior price to an unrelated party; otherwise 200% of the cost of materials and labor (Regulation 1507).
  • Service with incidental property. Use the true object test in the general table above (Regulation 1501).

Manufacturing and research equipment (CDTFA partial exemption: sellers)

  • Equipment used primarily in manufacturing, research and development, or electric power generation, storage or distribution may get a partial exemption (R&TC section 6377.1) if all three conditions are met: qualified person, qualified property, qualified use (CDTFA partial exemption guide).
  • The partial exemption rate is 3.9375%, so a qualifying sale is taxed at 3.3125% plus any district tax. The seller needs a timely CDTFA-230-M. The exemption runs to 30 June 2030.

District tax: which district, and how it is allocated

Sourcing rules (CDTFA district taxes)

SituationDistrict tax that applies
Over-the-counter sale at a location in a districtThe district sales tax where the sale takes place
Goods shipped (by the seller, its agent or a common carrier) out of the seller's district for use thereNo district sales tax of the seller's district
Seller engaged in business in the delivery districtCollect that district's use tax at the delivery address rate
Seller not engaged in business thereNot required to collect; the customer owes it, and the seller may collect it as a courtesy
Retailer over $500,000 (with related persons)Engaged in business in every district
Retailer under $500,000Engaged in business only where it has a presence, such as stored inventory or deliveries in its own vehicle

Allocating local and district tax on the return (CDTFA online filing instructions)

  • Schedule A (district tax, CDTFA-531-A2). Report every sale or purchase subject to district tax, by county and city, to the district where you are engaged in business and the tax applies.
  • Schedule C (local tax). Allocate the 1.25% local tax (1% Local Jurisdiction Fund and 0.25% Local Transportation Fund) to your registered California selling locations, where sales are made, negotiated or fulfilled.
  • Schedule B (local tax by county). Use it for construction jobsites, goods shipped from outside California with title passing outside the state, itinerant sales and vending machines.

Resale certificates: CDTFA-230 (Regulation 1668; Publication 103)

  • What it does. The seller must prove a sale is not at retail, unless it takes a certificate timely, in proper form and in good faith from a person selling goods who holds a seller's permit (or explains why none is needed).
  • Timely. Before you bill the buyer, within your normal billing and payment cycle, or at or before delivery. A later certificate is not retroactive.
  • Proper form. Any document (CDTFA-230, a letter, a purchase order) works if it has all the essential elements:
    • the buyer's signature (or an employee's or agent's);
    • the buyer's name and address;
    • the buyer's seller's permit number, or the reason no permit is needed;
    • the words "for resale" (not "exempt" or "non-taxable"), with an itemized list or general description of the goods;
    • the date (an undated certificate is still valid).
  • Good faith. It is presumed if the certificate has the essential elements and looks valid on its face. If the buyer claims to be buying for resale something it does not normally sell, get a certificate that names that specific property as bought for resale in the regular course of business.
  • Blanket certificates stay in effect until revoked in writing. With a "see purchase order" certificate, each order must mark the goods as for resale ("for resale", "resale = yes", "nontaxable", "taxable = no" or similar); a blank or zero tax amount alone is not enough.
  • Late or missing certificate. The seller is relieved only if it proves the goods were resold, are held for resale, or the buyer paid the tax to CDTFA.
  • Misuse. A buyer who gives a certificate for goods it knows it will not resell owes the tax plus a penalty of 10% of the tax or $500, whichever is greater, for each purchase made for personal gain or to evade tax. It may also face the 10% negligence or 25% fraud penalty. Knowing misuse to evade tax is a misdemeanor.
  • Drop shipments. A supplier that sells goods to a retailer not engaged in business in California, and delivers them to a California consumer on that retailer's instructions, is presumed to be the drop shipper. It is treated as the retailer and owes tax on the retail sale (R&TC section 6007). In most cases it escapes only by taking a timely, valid resale certificate showing the buyer's California seller's permit number. A certificate without that number generally does not work, except from an unregistered marketplace seller whose goods are resold through a registered facilitator (CDTFA Marketplace Facilitator Act guide).
  • Marketplace sellers that need not register may still give resale certificates, explaining that all their sales go through a registered facilitator (CDTFA Marketplace Facilitator Act guide).

Use tax

Businesses (Publication 110; CDTFA qualified purchaser rules)

  • When it applies. Use tax applies to goods bought for use, storage or consumption in California when no California tax was paid: purchases from out-of-state or foreign sellers who did not collect, and goods bought on a resale certificate and then used (other than for display or demonstration while held for sale). The rate is the sales tax rate where the goods are used.
  • Permit holders report use tax on their sales and use tax return.
  • Qualified purchasers. A business with no seller's permit or use tax registration must register as a "qualified purchaser" and file a yearly use tax return if, from 1 January 2024 to 31 December 2028, it makes more than $10,000 in purchases subject to use tax in a calendar year on which the tax was not paid to a retailer. Before 2024, and again from 1 January 2029, the test is at least $100,000 of gross receipts from business operations.

Individuals: the income tax return (FTB Form 540 booklet for 2025)

  • Where to report. Individuals report use tax on line 91 of Form 540. A number must be entered; if nothing is due, tick the box saying no use tax is owed or it was paid to CDTFA.
  • Who may not use line 91 for business purchases. Anyone who has or must hold a seller's permit, is otherwise registered with CDTFA for use tax, or makes more than $10,000 of purchases subject to use tax (excluding vehicles, vessels and aircraft) in the calendar year without paying the tax to a retailer. These report to CDTFA instead.
  • Worksheet or table. Items bought for $1,000 or more each, and business purchases, go on the Use Tax Worksheet at the rate for the place of use. Non-business items under $1,000 each may be estimated with the Estimated Use Tax Lookup Table, which is based on California AGI. Using the table means no further use tax is assessed on those small items.
  • Credit. Tax paid to another state on the same item is a credit, up to the California use tax on it.
  • Year. The 2026 Form 540 booklet is not yet published. The rules above are from the 2025 booklet; check the 2026 booklet before filing 2026 returns.

Worked cases

These cases use invented businesses. Where a rate is "assumed", it stands for the result of a CDTFA address lookup; always look up the real address and date.

  1. Remote seller crosses the line mid-year (CDTFA Wayfair FAQ). An Oregon seller with no California presence sold goods for delivery into California of $410,000 in 2025. By 31 August 2026 it has sold $300,000 on its own website and $190,000 through a registered marketplace: $490,000 in total. On 12 September 2026 a $15,000 website order takes the 2026 total to $505,000, which exceeds $500,000. It is not liable for use tax on that order or earlier ones, but must register and collect state, local and district use tax on its direct sales from the next order. The marketplace keeps collecting on the facilitated sales. Its district obligation runs at least to 31 December 2027. Had the 2026 total stopped at exactly $500,000, the test would not be met.
  2. Counter sale, shipped sale and district tax (CDTFA district taxes). A retailer's store is at an address where the lookup shows an assumed 9.50%. A customer buys a $2,000 table at the counter: tax is 2,000 x 9.50% = $190.00. Another $2,000 table goes by common carrier to an address with an assumed 7.75%. The retailer's sales exceed $500,000, so it is engaged in business in every district: 2,000 x 7.75% = $155.00, with the 0.50% district part ($10.00) on Schedule A. Were it under $500,000 with no presence in the customer's district, it would charge 2,000 x 7.25% = $145.00; its own district tax does not apply to goods shipped out for use elsewhere, and the customer owes the district use tax unless the retailer collects it as a courtesy.
  3. Software: download, disk, custom and hosted (Regulation 1502). A business at an address with the 7.25% base rate buys a $1,200 prewritten program by download with no media: no tax. If the same program came on a USB drive, tax would be 1,200 x 7.25% = $87.00 on the whole price. A $40,000 program written to its order: no tax. A $600 monthly subscription to hosted software it uses in a browser, with nothing downloaded or shipped: no transfer of tangible property, so no sales or use tax; the business should get written advice if the contract is large or includes any download.
  4. Grocery basket (Regulation 1602). A supermarket that does not meet the 80-80 rule, at an address with the 7.25% base rate, sells a cold sandwich for $8, hot soup for $6, a soda for $2, a candy bar for $3, vitamins for $20 and a bag of ice for $4. Exempt: sandwich and candy. Taxable: 6 + 2 + 20 + 4 = $32. Tax: 32 x 7.25% = $2.32.
  5. Quarterly prepayments (CDTFA prepayments). CDTFA has notified a retailer that it must prepay. Its January state and local liability is $30,000, so it prepays at least 30,000 x 90% = $27,000 by 24 February. In the second quarter, the prepayment due 24 June covers 1 May to 15 June: either at least 90% of that period's liability ($35,000 x 90% = $31,500) or 135% of the May liability ($22,000 x 135% = $29,700). If it had missed the January prepayment but filed the quarterly return on time, the penalty would be 6% of 90% of the liability: 30,000 x 90% x 6% = $1,620.
  6. Late quarterly return (R&TC section 6591). A quarterly filer owes $10,000 for April to June 2026, due 31 July 2026. It files and pays on 20 August 2026. The late filing and late payment penalties are each 10%, but together they are capped at 10% per return: $1,000, not $2,000. Interest runs for one month or fraction. Relief is possible for reasonable cause (see below).
  7. Individual use tax on a 2025 return (FTB Form 540 booklet for 2025). A resident with California AGI of $85,000 bought a $1,500 television and $500 of small items from out-of-state sellers that charged no tax. The television is $1,000 or more, so it goes on the worksheet at the assumed home rate of 9.50%: 1,500 x 9.50% = $142.50, entered as $143 because the worksheet uses whole dollars. The small items may be estimated from the lookup table: $8 for AGI of $80,000 to $89,999. Line 91: 143 + 8 = $151.

When to refuse or refer

  • Refer cannabis, fuel, tobacco and other special taxes and fees, and vehicle, vessel and aircraft use tax.
  • Refer partial exemption claims that are not plainly within the rules, construction contracts, leases, and material technology transfer agreements.
  • Refer a seller with unfiled past years to the Voluntary Disclosure Program before CDTFA contacts it. Unfiled years can be assessed for eight years, and the program may cut that to three (CDTFA Wayfair FAQ).
  • Refer notices of determination, appeals, fraud, and 40% penalty cases to a practitioner who handles CDTFA disputes (R&TC section 6597).
  • For hosted software, mixed bundles or any close call, get CDTFA's written advice: reasonable reliance on it can relieve tax, penalty and interest (Regulation 1705).
  • Do not state a local rate from memory; use the address lookup for the transaction date.

Filing and payment

  • CDTFA assigns the frequency from reported or expected taxable sales. A return is due even with no sales.
  • A due date on a weekend or state holiday moves to the next business day.
  • A payment started on the due date must be completed before midnight Pacific time (earlier for EFT accounts).

Prepayments (R&TC section 6471; CDTFA prepayments)

  • Who. A person whose estimated measure of tax liability averages $17,000 or more per month, and who has been notified in writing by CDTFA. Without the notice, there is no prepayment duty.
  • Quarters 1, 3 and 4. Prepay at least 90% of the state and local liability for each of the first two months, by the 24th of the following month (for example, January by 24 February).
  • Quarter 2. First prepayment: 90% of April, by 24 May. Second, by 24 June: 90% of the liability for 1 May to 15 June, or 135% of May.
  • Prior-year option. A business operating throughout the same quarter last year may prepay one-third of that quarter's reported measure (one-half for the second quarter-2 prepayment), times the current rate.
  • Penalty. A prepayment made late, but before the last day of the month after the quarter, costs 6% of the prepayment (R&TC section 6476). A prepayment not made by then, where the quarterly return and payment are timely, costs 6% of 90% of that month's liability (R&TC section 6477).

Missed prepayment6%See prepayments above
  • Interest. Simple interest for each month or fraction that tax is late, at the federal underpayment rate (IRC section 6621) plus three percentage points, reset every six months (the January rate applies July to December; the July rate January to June). Read the current rate on CDTFA interest rates.
  • Relief. Penalties are relieved where the failure was due to reasonable cause and circumstances beyond the person's control, with ordinary care and no willful neglect; the request is a statement under penalty of perjury (R&TC section 6592). Tax, penalty and interest can be relieved for reasonable reliance on CDTFA's written advice (Regulation 1705).

Assessment periods and records (R&TC section 6487; Regulation 1698)

  • Return filed. Three years from the end of the month following the period, or three years from the date the return was filed, whichever ends later.
  • No return filed. Eight years from the end of the month following the period.
  • Fraud or intent to evade. The three-year and eight-year limits in section 6487 do not apply.
  • Records. Keep sales and purchase records, certificates and supporting documents for at least four years, unless CDTFA authorizes a shorter period in writing. Keep them longer while an audit or appeal is open.

2025 periods and 2025 returns (CDTFA rate history; FTB Form 540 booklet for 2025)

  • The 7.25% base rate, the $500,000 test and the filing rules applied throughout 2025. Check a 2025 period against the district rate for that date, not today's.
  • Individuals report 2025 use tax on line 91 of the 2025 Form 540. The tax was due 15 April 2026. The automatic extension to 15 October 2026 is for filing: a return filed by then avoids the late filing penalty, but interest runs from 15 April 2026.
  • A qualified purchaser's yearly use tax return for 2025 was due 15 April 2026 (CDTFA filing dates).
