Additions to gross business profits
Interest received on obligations of states and political subdivisions other than NH (federal tax-exempt municipal interest); Net operating loss deductions taken for federal purposes (NH has its own NOL — see Section 2.7); Federal special deductions taken under IRC §§241–250 (corporate dividends-received deduction, etc.) — added back, then the NH-specific Section 3.5 dividends adjustment is computed separately; Compensation paid to partners or proprietors for personal services that exceeds the 'reasonable compensation deduction'; §168(k) bonus depreciation taken for federal purposes — NH does not conform, add it back; §179 expense in excess of the federal pre-2003 limit — historically NH capped §179 at $25,000, but for tax periods ending on or after December 31, 2017, NH conforms to the federal §179 limit as in effect under the IRC tie-in.
New Hampshire has no general personal income tax and no general sales tax, but it taxes business activity through two parallel filings: the Business Profits Tax (BPT) at 7.5% on net business profits and the Business Enterprise Tax (BET) at 0.55% on the enterprise value tax base of compensation, interest, and dividends paid. BET paid is a dollar-for-dollar credit against BPT, so most filers effectively pay the larger of the two. Both taxes apply to sole proprietors, partnerships, LLCs, and corporations conducting business in NH. The Interest & Dividends Tax was fully repealed for tax years beginning on or after January 1, 2025. The 2025 BPT filing threshold is $109,000 of gross business income; the 2025 BET filing threshold is $298,000 of either gross receipts or enterprise value tax base. Tax year 2025.
New Hampshire is famous for what it does not tax. It is one of nine US states with no broad-based personal income tax on wages, and one of five states with no general retail sales tax. There is no withholding from wages, no W-2 state line, no state Form 1040, no state sales-tax permit for retailers selling tangible personal property at retail in-state, and no use-tax self-assessment for consumers.
What New Hampshire does tax, and what this skill covers:
Business Profits Tax (BPT) under RSA 77-A — a 7.5% net income tax imposed on every business organization carrying on business activity within New Hampshire, including sole proprietorships, partnerships, LLCs (regardless of federal classification), corporations, S-corporations, trusts, and non-profit organizations to the extent of unrelated business income. The BPT is imposed at the entity level even on pass-through entities — there is no flow-through to owners for NH purposes. This is the single most important point for federal practitioners new to NH: a Schedule C filer with NH-source business income files a NH BPT return in the entity's own right.
Business Enterprise Tax (BET) under RSA 77-E — a 0.55% tax on the "enterprise value tax base" (EVTB), which is the sum of compensation paid, interest paid, and dividends paid by the enterprise. The BET is a value-added-tax-like measure that captures economic activity even when the entity has zero or negative profits. The BET paid for a tax period is a credit against the BPT for the same period; any excess BET carries forward five years.
What this skill does NOT cover and refers out:
The administering agency for BPT and BET is the New Hampshire Department of Revenue Administration (NH DRA), Concord, NH.
Further scheduled reductions tied to general-fund revenue triggers have been paused by the legislature. Assume 7.5% for any tax period ending in calendar 2025 unless a later session law moves the rate.
Taxable base by NH business organization type (RSA 77-A:1, II)
| NH business organization | Federal starting point |
|---|---|
| Sole proprietorship | Schedule C, Line 31 net profit (or Schedule F net farm profit) |
| Partnership | Form 1065 ordinary business income plus separately stated items |
| LLC taxed as partnership | Same as partnership |
| LLC taxed as disregarded entity | Schedule C of the sole owner |
| S-corporation | Form 1120-S ordinary business income plus separately stated items (NH does not recognize the S election — see Section 2.5) |
| C-corporation | Form 1120 taxable income before NOL and special deductions |
| Trust or estate with business income | Form 1041 fiduciary taxable income from business activity |
Practical implication for the S-corp election decision: in NH, the S-corp election saves federal SE tax but provides no NH-side benefit (and adds NH payroll filings — see Section 7.6). The federal break-even analysis must therefore be net of the additional NH compliance cost and the loss of the reasonable-compensation deduction (which the S-corp shareholder would replace with a federally deductible W-2 wage — economically similar but structurally different).
For a single freelancer or small-business owner with one entity, combined-return rules are not triggered. They become relevant when the owner controls multiple operating entities (e.g., an operating LLC and a real-estate holding LLC under common ownership conducting a unitary business).
To make the mechanic concrete: take a sole proprietor with $200,000 of federal Schedule C net profit, no other NH modifications, and 100% NH apportionment.
If the proprietor instead substantiates $150,000 of reasonable compensation (industry comparables documented):
A NH LLC taxed as a partnership pays during 2025:
EVTB = $180,000 + $40,000 + $8,000 + $0 = $228,000 BET = $228,000 × 0.55% = $1,254
A NH-resident freelance software developer with one corporate client in California and one in NH:
If federal Schedule C net profit after NH modifications and RCD is $80,000, NH apportioned base = $80,000 × 25% = $20,000. BPT = $20,000 × 7.5% = $1,500.
This is one of the biggest planning opportunities for NH-based service businesses: market-based sourcing combined with no throwback can apportion a large share of income out of NH.
This is the most important interaction in NH business taxation.
Common patterns of BPT vs BET dominance
| Business type | Typical pattern |
|---|---|
| Sole prop, low-overhead freelancer with high margin | BPT > BET — BET fully credited, BPT dominates |
| Labor-intensive service firm (consulting, agency, payroll-heavy) | BET > BPT — BET dominates, may build carryforward |
| Capital-intensive corp with low headcount, high profit | BPT > BET — BPT dominates |
| Real-estate LLC with mortgage interest and modest net income | BET often > BPT — BET dominates due to interest in EVTB |
| Loss year | BET still owed if EVTB threshold exceeded; full BET carries forward 5 years against future BPT |
Forms by entity type
| Entity | BPT form | BET schedule | Combined? |
|---|---|---|---|
| Sole proprietor | NH-1040 | BET-PROP | Yes — single return |
| Partnership / LLC taxed as partnership | NH-1065 | BET | Yes |
| C-corporation | NH-1120 | BET | Yes |
| S-corporation (treated as C for NH) | NH-1120 | BET | Yes |
| LLC taxed as disregarded entity | Flows to owner's NH-1040 (if owner is individual) | BET-PROP | Yes |
| Trust / estate with business income | NH-1041 | BET | Yes |
| Unitary combined group | NH-1120-WE | BET-WE | Yes |
All forms include the Schedule R (apportionment), Schedule IV (NH NOL), and applicable credit schedules.
This is the most common surprise for federal practitioners helping an out-of-state client move to NH: there is no state W-2 box 17, but there is still a state UI filing.

In this example, the labor-intensive business generates a significant BET, but the BPT still exceeds it because the partnership has substantial profit margin. The members' RCD efficiently reduces BPT but does NOT reduce BET (compensation is in EVTB whether characterized as a partner draw, a guaranteed payment, or W-2 wages).

This is the typical pattern for a profitable, capital-light services C-corp: BPT dominates and BET is essentially a minimum-floor that is fully absorbed.
Facts. Same Granite Marketing LLC as Example B, but in 2026 the firm has a bad year:
BPT.

Total 2026 NH tax: $4,125 BET, no BPT. The $4,125 sits in carryforward and reduces 2027–2031 BPT until used (FIFO).
Do not confuse I&D Tax with BPT/BET. The repeal of I&D Tax does NOT reduce the BPT or BET liability of a business — those continue at 7.5% and 0.55% respectively. A common client misunderstanding (2025 onward): "NH repealed the income tax, so I don't owe anything." Wrong — they likely still owe BPT and/or BET if they operate a business.
Step-by-step for an NH-resident sole proprietor or single-member LLC freelancer at year-end 2025:
Threshold check. Compute 2025 gross business income from federal Schedule C Line 1 (or Schedule C-EZ legacy). If ≤ $109,000, no BPT return is required — but still check BET (Step 3). If > $109,000, a BPT return is required.
Reasonable compensation analysis. Determine the proprietor's reasonable compensation:
BET threshold check. Compute EVTB = SE compensation (Schedule SE Line 4, capped at FICA wage base) + interest paid + dividends paid. Compute gross receipts. If either EVTB > $298,000 OR gross receipts > $298,000, a BET return is required.
NH modifications and apportionment. Apply NH modifications (interest on non-NH munis added back, US Treasury interest subtracted, bonus depreciation added back if any) and compute NH sales-factor apportionment using market-based sourcing.
BPT and BET computation. Compute BPT before credits and BET. Apply BET credit against BPT.
Federal-state coordination.
File. Use Granite Tax Connect to e-file Form NH-1040 (proprietorship) by April 15, 2026, for tax year 2025. Pay BPT and BET via the same return; remit estimated payments for 2026 quarterly starting April 15, 2026.
Closeout. If the business is winding down, mark "final return" on the form; the DRA closes the BPT/BET account and stops sending non-filer notices.
Missing the BET when business has a loss. BET is owed even at a loss if EVTB threshold is exceeded. A loss-year client is at risk of forgetting BET.
Claiming reasonable compensation for a C-corp shareholder-employee. RCD is for proprietors and partners only. C-corp and S-corp shareholder-employees take a W-2 instead.
Excessive RCD without substantiation. Anything above $75,000 needs documentation. The DRA audits this.
Treating S-corp income as flowing through to NH. Wrong — S-corp is taxed at the entity level for BPT.
Forgetting bonus depreciation add-back. If federal Schedule C took bonus depreciation, NH starts higher.
Throwback that doesn't exist. Some practitioners default to applying throwback because their home state has one; NH does not — out-of-state services with market-based sourcing simply stay out of the NH numerator.
Double-counting RCD against both BPT and BET. RCD reduces BPT only. The same compensation is fully in BET regardless.
Claiming a 2025 I&D Tax return. The tax does not exist for 2025. A client who received a 1099-INT does not file a NH return for that interest in 2025.
Missing the combined-return trigger. Two LLCs > 50% commonly owned and unitary = combined return, not two separate returns.
Estimated-payment underpayment. The NH safe harbor uses prior-year tax (or 110% if prior-year tax > $40,000). Clients who switched from a loss year to a profit year must pay current-year estimates because 100% of prior-year tax was zero — they cannot use the prior-year safe harbor as a shield.

Subtractions from gross business profits
Interest on US obligations included in federal income; Foreign dividend gross-up under IRC §78; A portion of dividends received from a unitary affiliate to the extent already included in combined-return income; The reasonable compensation deduction (RSA 77-A:4, III) for sole proprietors and partners; NH NOL carryover — see Section 2.7.RSA 77-A:4, II; RSA 77-A:4, IV; RSA 77-A:4, III
Reasonable compensation deduction
Because the BPT applies at the entity level to pass-through structures, a sole proprietor or partner who works full-time in the business would be taxed at 7.5% on the entire net profit — including the portion that is really compensation for their labor — unless an adjustment is made. RSA 77-A:4, III provides the reasonable compensation deduction: an amount equal to the fair compensation paid for the personal services of the proprietor or partner is deductible in arriving at gross business profits.RSA 77-A:4, III; Rev 304.04
Who qualifies for RCD
The deduction is available to a proprietor of a sole proprietorship or a partner in a partnership (including an LLC taxed as a partnership) who renders actual personal services to the business. It is not available to a shareholder-employee of a C-corporation or S-corporation — those persons take a W-2 wage that is already deductible at the entity level on the federal return.RSA 77-A:4, III; Rev 304.04
How much is reasonable
"Reasonable compensation" is the amount that would be paid to a person at arm's length for the same services in the same industry and geography. It is the same factual standard the IRS applies to S-corporation reasonable-wage cases, and the NH DRA has historically looked at: Education, training, and certifications of the proprietor/partner; Hours actually worked in the business; Comparable wages in the local labor market (BLS OES data, NH Employment Security wage surveys); Industry norms (an attorney sole proprietor with ten years of experience would expect $120,000+; a part-time craft seller might be $20,000); Whether the proprietor has other employment.RSA 77-A:4, III
RCD safe harbor
75000Indexed amounts for 2025 (skill text)
Substantiation above the safe harbor
A taxpayer claiming compensation above $75,000 must maintain: A written statement of duties performed; Hours worked records (timesheets, calendar, project logs); Comparable-wage evidence (BLS data, recruiter quotes, industry surveys, prior W-2 history); Board-equivalent documentation if the entity has co-owners. The DRA can disallow the excess on audit and rebill BPT plus interest and penalty.RSA 77-A:4, III
RCD ceiling
The deduction cannot exceed the gross business profits before the deduction — i.e., it cannot create or increase a BPT loss. If the business has $30,000 of profit before the deduction and the proprietor claims $75,000 of reasonable compensation, the deduction is capped at $30,000 and the BPT base is zero; the unused $45,000 does NOT carry over as a NOL because it was never compensation actually paid.RSA 77-A:4, III
Multiple proprietors/partners
Each partner computes a separate reasonable-compensation deduction based on their own services. The sum is deducted at the partnership level.RSA 77-A:4, III
Interaction with self-employment
The reasonable compensation deduction is for NH BPT only. It does NOT affect federal Schedule C net profit, does NOT affect federal SE tax, and does NOT change the federal QBI computation. It is purely a NH-side modification.RSA 77-A:4, III
S-corp treated as C-corp for BPT
NH does not recognize the federal S election for BPT purposes. An S-corporation is taxed at the entity level as if it were a C-corporation for BPT — the corporation pays 7.5% on its NH-apportioned profits. The shareholders do not separately report their pro-rata share of S-corp income on a NH return (and there is no NH personal income tax for them to report it on anyway).
Combined return requirement
For unitary business groups, NH requires a combined return when there is more than 50% common ownership (direct or constructive under IRC §1563) and the entities are engaged in a unitary business under the three-unities test. The combined group reports a single NH BPT return on Form NH-1120-WE.RSA 77-A:1, XV; Rev 305.03
Water's-edge regime
NH uses a water's-edge combined-return regime — foreign corporations whose business activity outside the United States is 80% or more of their worldwide activity are excluded from the combined group. There is no worldwide combined election.
NH NOL computation basis
NH has its own net operating loss carryover. NH NOL is computed using NH modifications (not federal NOL).RSA 77-A:4, XIII
Carryforward period
10 years for losses generated in tax periods ending on or after December 31, 2022. Earlier-period losses retain their original carryforward (5 years for pre-2013, etc.) — review carryover schedules carefully.HB 1221, Chapter 144, Laws of 2022
No carryback
No carryback of NH NOL.RSA 77-A:4, XIII
Per-year deduction cap
An apportioned NH NOL deduction is capped at the lesser of the carryover or the gross business profits before the NOL deduction.RSA 77-A:4, XIII
80% federal limitation does not apply
80%-of-taxable-income federal limitation under IRC §172(a)(2)(B) does not apply for NH purposes.IRC §172(a)(2)(B)
Bonus depreciation non-conformity
NH does not conform to federal bonus depreciation (§168(k)) at all. For an asset placed in service in 2025 that took 60% federal bonus, NH requires the asset to be depreciated using MACRS without bonus — creating a permanent year-of-acquisition timing difference that reverses over the asset's recovery period. Maintain a separate NH depreciation schedule from year one.
§179 conformity
For §179, NH currently conforms to the federal §179 limit as of the IRC reference date in RSA 77-A:1, XX. The 2025 IRC reference date should be confirmed against the NH DRA's published IRC update bulletin; if NH is still tied to a pre-OBBBA IRC, the federal §179 limit of $2,500,000 (2025, OBBBA) may differ from the NH limit.RSA 77-A:1, XX
2025 BPT filing threshold
109000
Filing requirement below threshold
A taxpayer below the threshold is not required to file a BPT return. A taxpayer that has filed in prior years and falls below the threshold should file a final-return / no-tax-due indicator to close the account; the DRA will otherwise issue a non-filer notice. The threshold applies per business organization, not per owner. A married couple operating two separate proprietorships each tests its own threshold.
BPT and BET threshold independence
BPT threshold and BET threshold are independent. A taxpayer below the BPT threshold may still be above the BET threshold and required to file the BET. The reverse is also true.

Enterprise value tax base
The BET is imposed on the 'enterprise value tax base,' which under RSA 77-E:3 is the sum of three components, each as adjusted by NH-specific modifications: (1) Compensation paid or accrued; (2) Interest paid or accrued; (3) Dividends paid.RSA 77-E:3
Compensation component of EVTB
Includes: Wages and salaries paid to employees (federal Form 941 Line 2 / Form W-3 Box 1, with reconciliations); Commissions, bonuses, severance; Net earnings from self-employment of proprietors and partners up to the FICA wage base for the year (i.e., the 'self-employment compensation' of the proprietor or partner is included in the BET base even though no W-2 is issued); Deferred-compensation accruals that are deductible federally in the current period; Fringe benefits that are federally taxable to the recipient (health insurance is NOT included if excluded from the employee's federal wages); Compensation paid to independent contractors who are reclassified as common-law employees under federal rules — but bona fide §3121 independent-contractor payments are NOT compensation (they may be the contractor's own BET base). For a sole proprietor with no employees, the 'compensation paid' item is the proprietor's own self-employment net earnings (the same number as Schedule SE Line 4) capped at the year's FICA wage base ($176,100 for 2025).RSA 77-E:3
Interest component of EVTB
Interest paid or accrued during the tax period — interest expense on debt, including: Bank loan interest, business credit-card interest, mortgage interest on business real property; Imputed interest under IRC §483 and §7872 to the extent deductible; Excludes: interest paid to the US government on tax deficiencies (not deductible federally); interest already capitalized to inventory under §263A. Interest paid to a partner or proprietor on a loan from the partner/proprietor IS included if the entity deducts it federally.RSA 77-E:3
Dividends component of EVTB
Dividends paid during the tax period — only by C-corporations and other dividend-paying entities. For C-corporations: all dividends declared during the period out of accumulated earnings and profits. For partnerships and proprietorships: dividends are zero by definition because distributions to partners and proprietors are not federal-tax dividends. For S-corporations: distributions are NOT dividends for BET purposes (they are returns of basis); only constructive dividends under federal §301 are included. Stock dividends and stock splits not taxable to recipients federally are excluded.RSA 77-E:3
Apportionment mechanics for EVTB
For multi-state enterprises, the EVTB is apportioned to NH using payroll, interest, and dividends factors specific to NH activity. The mechanics differ from BPT apportionment (Section 5): Compensation is apportioned by NH payroll / total payroll; Interest is apportioned by NH interest expense location (generally where the related business activity occurs); Dividends are apportioned to the commercial domicile. For a single-state NH business, apportionment is 100%.RSA 77-E:4
Single sales factor apportionment
For tax periods ending on or after December 31, 2022, NH apportions BPT using a single sales factor — the ratio of NH sales to everywhere sales. This is the result of HB 10, Chapter 346, Laws of 2019, as further amended, which phased out the historic three-factor formula: Pre-2020: three-factor with double-weighted sales (property, payroll, sales-sales); 2020–2021: transition weighting; 2022 and forward: 100% sales factor.HB 10, Chapter 346, Laws of 2019
Sourcing of receipts rules
Sales of tangible personal property are sourced to the destination state (where the property is delivered to the customer). Sales of services are sourced using market-based sourcing to the location where the customer receives the benefit of the service (for tax periods ending on or after December 31, 2021). Sales of intangibles (royalties, license fees) are sourced to where the intangible is used. Throwback / throwout: NH does NOT have a throwback rule. Sales to a state where the taxpayer is not taxable are NOT thrown back to NH — they remain in the everywhere denominator only (a 'nowhere sale' benefit).RSA 77-A:3, II; Rev 304; Chapter 91, Laws of 2021
Finnigan rule for combined groups
For combined groups, the sales factor is computed at the group level (Joyce or Finnigan — NH follows Finnigan: a sale by any group member into NH is a NH sale of the group, regardless of which member made it).
BET credit against BPT sequence
Under RSA 77-A:5, X, the BET paid for a tax period is allowed as a credit against the BPT for the same tax period. The credit is applied after all other BPT credits. Sequence: 1. Compute BPT before credits (Section 2). 2. Compute BET (Section 4). 3. Subtract BET from BPT. 4. If BPT > BET: BPT due is BPT − BET; BET is fully credited; total NH tax = BPT. 5. If BET > BPT: BPT due is zero; BET due is the full BET amount; excess BET carries forward up to 5 tax years (RSA 77-A:5, X(b)). 6. Total NH tax in any year is therefore the greater of BPT or BET (subject to credit carryover dynamics).RSA 77-A:5, X; RSA 77-A:5, X(b)
BET carryforward mechanics
Excess BET (BET in excess of BPT for the year) carries forward five tax periods and is creditable against BPT in those years. The carryforward is FIFO — oldest credit used first. Unused after five years expires.
Common patterns of BPT vs BET dominance
| Business type | Typical pattern | |---|---| | Sole prop, low-overhead freelancer with high margin | BPT > BET — BET fully credited, BPT dominates | | Labor-intensive service firm (consulting, agency, payroll-heavy) | BET > BPT — BET dominates, may build carryforward | | Capital-intensive corp with low headcount, high profit | BPT > BET — BPT dominates | | Real-estate LLC with mortgage interest and modest net income | BET often > BPT — BET dominates due to interest in EVTB | | Loss year | BET still owed if EVTB threshold exceeded; full BET carries forward 5 years against future BPT |
Combined filing norm
Because of the credit interaction, most NH business taxpayers file both BPT and BET on a combined return form (NH-1120, NH-1065, or NH-1040), with the BET computed on a Schedule BET attached. The BPT and BET share one set of payment vouchers, one estimated-tax schedule, and one return.

Due date - sole prop and partnership/LLC
15th day of the 4th month after year-end. For calendar-year filers, April 15 following the close of the tax year — same as federal Form 1040 / Form 1065.
Due date - C-corporation and S-corporation
15th day of the 4th month after year-end (note: NH uses the 4th month for corporations, NOT the 3rd month as some states do that follow federal Form 1120-S timing). For calendar-year filers, April 15.
Due date - combined group
Same as the parent's form due date.
Automatic extension
NH grants an automatic 7-month extension for BPT and BET filing if 100% of the tax due is paid by the original due date. No extension form is required if no payment is needed; otherwise file Form BT-EXT with payment. The extension is for filing only — interest accrues on any unpaid tax from the original due date.

E-filing and payment methods
NH DRA's Granite Tax Connect portal supports e-file for NH-1120, NH-1065, NH-1040 (BPT), and the BET schedules. Paper filing is still permitted. Estimated payments may be made via ACH debit, ACH credit, check with voucher (Form BT-ESTIMATE), or credit card (with a third-party convenience fee).
S-corp payroll filing obligations
If a NH business operates as an S-corporation and pays the owner a federal W-2 wage, the entity must: Register as a NH employer with NH Employment Security (DES) for unemployment insurance; File Form NHES-0061 quarterly UI wage reports; Pay state UI tax (rate varies; new employers historically pay 2.7%); No state income tax withholding is required — NH has no PIT to withhold against.
Combined return requirements
A combined return on Form NH-1120-WE is required when both: 1. Two or more business organizations are members of a unitary business (functional integration, centralization of management, economies of scale — the three unities under Mobil Oil and Container), AND 2. There is more than 50% common ownership (direct or constructive under §1563 attribution).
Water's-edge limit for combined groups
NH applies a water's-edge limit: a foreign corporation with 80%-or-more foreign business activity is excluded from the combined group. There is no worldwide-combined election.
Single-NH-nexus-member rule
A single entity that is the only NH-nexus member of a unitary group still files a combined return — it does not get to file as a separate entity merely because its affiliates have no NH nexus. The other group members' apportionment factors and pre-apportionment income enter into the NH combined computation; only the NH-nexus portion is taxed.
BET computation for combined groups
BET is computed at the combined-group level: the group's total compensation, interest, and dividends are summed (after eliminating intercompany items) and apportioned to NH using the group's NH payroll / total payroll, NH interest / total interest, and NH dividends / total dividends factors.
Federal deductibility of BPT and BET
Both BPT and BET are deductible on the federal return as state and local taxes paid in the conduct of the trade or business: On Schedule C as 'Taxes and licenses' (Line 23) for a sole proprietor; On Form 1065 / 1120-S / 1120 as a business expense for entities; They are NOT subject to the $10,000 individual SALT cap because they are paid at the entity level on a business — they are above-the-line business deductions.
Cash-basis deduction timing
The deduction is on the cash basis for cash-basis taxpayers — i.e., the BPT and BET deducted on the 2025 federal return are amounts actually paid in 2025 (estimated payments for Q1–Q4 2025 plus any 2024-year balance due paid in 2025, less any 2024 refund received in 2025 to the extent it was deducted in 2024 — recapture under the tax-benefit rule).
No PTET needed
Because BPT is already imposed at the entity level (not as a pass-through to owners), NH does not need and does not have a separate Pass-Through Entity Tax (PTET) election like CA, NY, NJ, etc. The structure of the BPT effectively functions as a built-in PTET, and the SALT cap workaround is automatic.
No coordination with federal QBI/SE tax/retirement
NH BPT does not reduce federal QBI, does not affect federal SE tax (Schedule SE is unaffected by NH BPT), and does not affect federal retirement-plan contribution limits. The reasonable compensation deduction is a NH-only concept and does not become a federal W-2.
I&D Tax repeal
The NH Interest and Dividends Tax (I&D Tax) under RSA 77 — a 5% personal tax on individuals' interest and dividend income — was fully repealed for tax years beginning on or after January 1, 2025.RSA 77; Chapter 79, Laws of 2023 (HB 2, 2023 session)
