US state conformity to federal bonus depreciation (§168(k)) and §179: 2026 matrix, with 2025 return notes

State-by-state matrix, tax year 2026 with 2025 return notes, of how each state income tax treats federal bonus depreciation under IRC section 168(k), the section 168(n) qualified production property allowance, and section 179 expensing: conformity date, whether the state follows or decouples, the add-back and recovery method, the state section 179 limit, and each state's response to the One Big Beautiful Bill Act. States that could not be verified are marked check.

The full Guide

Figures are for tax year 2026 unless a line says 2025. Federal amounts come from Rev. Proc. 2025-32 and IRS Publication 946 (2025), after the One Big Beautiful Bill Act (P.L. 119-21, "OBBBA"). Each state row was checked on 25 September 2026 against that state's revenue department or legislature. A row marked check could not be confirmed from an official page on that date: do not rely on it until you have read the state's current instructions. A separate section covers 2025 returns. Extended 2025 federal returns are due by October 15, 2026 (IRS extensions).

Scope and who this is for

  • Covers: individuals with business or rental income (Schedule C, E or F, and owners of partnerships and S corporations) who claimed federal bonus depreciation under IRC §168(k), the §168(n) allowance for qualified production property, or §179 expensing, and who file a state income tax return.
  • Does not cover: C corporation returns (rules often differ; Florida is noted only because it has no personal income tax), franchise, gross-receipts and business-activity taxes, §163(j) interest, net operating losses and research expensing under §174A.
  • Where our state Guides go further: Connecticut, Arkansas, Delaware, Kentucky, Maryland, New York, California and Virginia each have their own Guide (for example ct-income-tax, ca-540-individual-return). This matrix uses the same rules; use the state Guide for the full return.

Ask the client first

  • Which tax year is being prepared (2025 or 2026), and in which states does the client file (residence, and every state where the business or a pass-through has income)?
  • For each asset: the date it was acquired (the date of any written binding contract), the date it was placed in service, its cost, its MACRS class and life, and whether it is new or used.
  • Did the federal return claim §168(k) bonus depreciation, the §168(n) allowance, or §179? Was the 40% (or 60%) transition election made for the first tax year ending after January 19, 2025 (26 U.S.C. §168(k)(10))? Was an election out of bonus made for any class?
  • The fixed-asset register from prior years, with each state's separate basis and depreciation, and any add-backs still being recovered (Connecticut, Minnesota, North Carolina and Ohio spread recoveries over later years).
  • For pass-through owners: the state K-1 schedules showing the entity's bonus and §179 amounts, and whether the entity already made the adjustment (some states adjust at entity level, others at owner level).
  • Any disposal of an asset that had a state adjustment, since state gain or loss differs from federal.

The method, step by step

  1. Fix the federal numbers first. For each asset, split federal depreciation into §179, §168(k) or §168(n) allowance, and regular MACRS. Check the acquisition date: property acquired after January 19, 2025 gets 100% bonus; property acquired earlier and placed in service in 2025 gets 40% (Pub. 946).
  2. Find each state's row in the matrix below. Use the table for the year being prepared; several states changed their rules for 2026 (Delaware, Oregon, Hawaii, Arizona, Minnesota).
  3. Recompute state depreciation the way the state requires: no bonus at all (most decoupled states), a reduced bonus (Delaware 2026), or federal bonus with a percentage add-back and a fixed recovery (Connecticut, Minnesota, North Carolina, Ohio). Apply the state's own §179 limit if it has one.
  4. Enter the add-back on the state form named in the row, in the year the federal deduction was taken.
  5. Schedule the recovery. Either a fixed fraction in later years (Connecticut, Minnesota, North Carolina, Ohio), or the extra state depreciation each later year until the asset is fully depreciated. Keep a separate state depreciation schedule for every asset; the state basis differs from federal.
  6. On disposal, compute state gain or loss with the state basis. Several states say so expressly (Maine, New Jersey, Illinois, Wisconsin).
  7. Nonresidents and part-year residents: the add-back and subtractions follow the state's sourcing and apportionment rules. Record open recoveries for next year.

  • Qualified property is generally tangible property depreciated under MACRS with a recovery period of 20 years or less, certain computer software, water utility property, and qualified film, television, live theatrical and sound recording productions (Pub. 946).
  • Election out: made for a whole class of property for the year, and covers all qualified property in that class placed in service that year. It is made on a timely filed return (including extensions) and can be revoked only with IRS consent (26 U.S.C. §168(k)(7); Pub. 946). Electing out avoids the state bonus add-back, at a federal cost.

  • §179 is also limited to taxable income from the active conduct of a trade or business (the business income limit), and applies to each taxpayer, not each business (Pub. 946).

State matrix, tax year 2026

Read the row for the year you are preparing. "Follows" means no state adjustment for federal bonus depreciation. Where a state has not yet published 2026 forms, the row gives the rule in force and the 2025 form that carries it.

No personal income tax on wages or business income

Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington and Wyoming have no broad personal income tax on wages or business income, so a resident sole proprietor or pass-through owner has no individual add-back there. New Hampshire does not tax wages; its business profits tax can reach some sole proprietors (check). Entity-level taxes are outside this Guide; check each one separately:

  • Florida corporate income tax: add back §168(k) for property placed in service before January 1, 2027, and subtract one seventh of the addition each year over seven years (F-1120 instructions).
  • Texas franchise tax, Tennessee franchise and excise tax, Washington B&O tax and the New Hampshire business profits tax: check.

States we could not verify (check)

Idaho, Kansas, Massachusetts, Michigan, Mississippi, New Mexico, Rhode Island, Utah and West Virginia: check. On 25 September 2026 their revenue department or legislature pages either refused our requests or did not state the rule. Do not assume they follow federal law. Read the state's 2025 individual instructions and any 2026 conformity act. Points to confirm:

  • Idaho, New Mexico: confirm any 2026 conformity act and its treatment of §168(k) and §168(n).
  • West Virginia: the Governor proposed restoring full bonus depreciation for the 2026 session (Governor's release); confirm what was enacted.
  • Michigan: confirm its IRC conformity date and its treatment of §168(k) and §168(n).
  • Massachusetts, Rhode Island, Mississippi, Kansas, Utah: confirm whether the state decouples from §168(k) and whether it has its own §179 limit.

Worked cases

Case 1: Connecticut, 2026 (CT-1040 instructions)

A sole proprietor deducts $100,000 of bonus depreciation and a $40,000 §179 deduction on the 2026 federal return. Connecticut additions: $100,000 (line 36) and 80% × $40,000 = $32,000 (line 36a). In each of 2027 to 2030, subtract 25% × $100,000 = $25,000 (line 48a) and 25% × $32,000 = $8,000.

Case 2: North Carolina, 2025 return (D-401 instructions)

Federal bonus depreciation of $50,000 in 2025. Add 85% × $50,000 = $42,500 on the 2025 return. Deduct 20% × $42,500 = $8,500 in each of 2026 to 2030.

Case 3: Minnesota, 2026 (§290.0131; §290.0132)

Federal bonus depreciation of $50,000 in 2026, no disallowed loss and no federal NOL. Add 80% × $50,000 = $40,000. Subtract one-fifth of $40,000 = $8,000 in each of 2027 to 2031.

Case 4: Ohio, 2026 (IT 1040 instructions)

Federal bonus depreciation of $60,000; the business did not raise Ohio withholding and has no federal NOL. Add 5/6 of $60,000 = $50,000. Deduct 1/5 of $50,000 = $10,000 in each of the next five years. If a later year has an NOL, NOL carryback or NOL carryforward, that year's $10,000 is not claimed then but carried to the next year without one. Confirm the line numbers in the 2026 instructions when published.

Case 5: California §179, 2026 (3885A instructions)

Machinery costing $210,000 is placed in service and fully expensed federally. California limit: $25,000 − ($210,000 − $200,000) = $15,000, provided business income is at least that. The remaining $195,000 is depreciated on form 3885A with no bonus.

Case 6: Delaware, 2026 (Delaware memo 2025-2)

A machine costing $100,000 is acquired and placed in service in June 2026, with 100% federal bonus. Delaware bonus is 20% × $100,000 = $20,000. The remaining $80,000 is depreciated under regular MACRS. The Delaware addition is the federal deduction minus the Delaware depreciation for the year.

Case 7: Indiana §179, 2026 (IB 118)

Property costing $225,000 is expensed in full under federal §179. Indiana allows $25,000, so add back $225,000 − $25,000 = $200,000 (code 105). The $200,000 is then depreciated for Indiana, and each later year's Indiana depreciation is a deduction.

Case 8: federal acquisition date, 2025 (Pub. 946)

Equipment was bought under a written binding contract signed on January 10, 2025 and placed in service in March 2025. It counts as acquired before January 20, 2025, so federal bonus is 40%, not 100%. Every state add-back in this Guide starts from that 40% figure.

2025 returns (tax year 2025; extended federal deadline October 15, 2026)

  • Federal: 100% bonus for property acquired after January 19, 2025; 40% for property acquired earlier; §179 limit $2,500,000, reduction above $4,000,000, SUV cap $31,300 (Pub. 946).
  • Delaware and Oregon follow federal bonus for 2025; their decouplings start in 2026.
  • Hawaii 2025: no bonus and the $25,000 §179 limit under the earlier conformity law (N-11 instructions).
  • Arizona: the 2026 Act adopted the P.L. 119-21 changes retroactively for 2025 (enacted fact sheet).
  • Virginia: the December 31, 2025 conformity date was enacted February 20, 2026 and applies to 2025. Returns filed before then may need amending (TB 26-1).
  • New York: it does not conform to §168(n) for tax years beginning on or after January 1, 2025. If a 2025 return has been filed, an amended return must be filed to report the §168(n) modifications (Notice N-26-1).
  • Minnesota: until Laws 2026, ch. 128, Minnesota used the IRC as amended through May 1, 2023, so bonus on 2025 returns filed before that law was figured under pre-OBBBA rules. The law moved the date to May 1, 2026, effective retroactively with the federal changes. Check the department's guidance on whether a 2025 return already filed should be amended (Laws 2026 ch. 128).
  • Georgia 2025 §179: $2,500,000, phase-out $4,000,000 (GA 4562 instructions). Arkansas 2025 §179: $1,250,000, cost limit $3,130,000 (AR instructions).
  • South Carolina 2025: IRC as amended through December 31, 2024 (SC1040 instructions).

When to refuse or refer

  • Refer any state marked check until you have read that state's current instructions and any 2026 conformity act.
  • Refer if the client's records do not show each asset's state basis in a decoupled state and the asset is several years old; rebuilding the schedule is a separate engagement.
  • Refer C corporation returns, franchise and gross-receipts taxes, and combined or unitary filings.
  • Refer Oregon 2026 returns until the SB 1507 referendum outcome is known.
  • Refer §168(n) qualified production property; the federal election and the state treatment are both new.
  • Do not give a combined federal-and-state figure where the federal acquisition date (before or after January 20, 2025) is not documented.

Filing and payment

  • Federal: Form 4562 for §179, bonus and MACRS; the §179 election and any election out of bonus are made on a timely filed return, including extensions (Pub. 946).
  • State: the add-back and later recovery go on the form named in each row (for example CT-1040 Schedule 1, NC Schedule S, Ohio Schedule of Adjustments, IL-4562, Indiana codes 104 and 105, CA form 3885A and Schedule CA, MD Form 500DM, NY Form IT-398 and IT-225, NJ GIT-DEP).
  • An add-back raises state taxable income in the year of purchase. Check the client's state estimated payments for that year.

Completion checklist

  • Federal acquisition date and bonus rate confirmed for each asset; any election out or 40% election recorded.
  • Every filing state identified, and its row read for the correct year (2025 or 2026).
  • States marked check confirmed from the state's own current instructions.
  • State depreciation recomputed where required; state §179 limit applied (California, Hawaii, DC, Indiana, Maryland, New Jersey, North Carolina, Kentucky, Arkansas).
  • Add-backs entered on the right state line; fixed-fraction recoveries scheduled (Connecticut, Minnesota, North Carolina, Ohio).
  • Prior-year recoveries claimed this year.
  • Disposals: state gain or loss computed on state basis.
  • Pass-through K-1 state amounts reconciled, with no double adjustment.
  • State estimated payments reviewed.
