West Virginia Bonus Depreciation: Conforms Today, Frozen After 2026-01-01.
West Virginia's conformity cutoff currently recognizes federal changes through December 31, 2025 — after OBBBA, so the restored 100% bonus applies. But the statute itself states that no federal amendment made on or after January 1, 2026 may be given effect until the legislature moves the date forward again.

The 30-second answer: West Virginia conforms to federal §168(k) bonus depreciation today. Its conformity cutoff is static but rolled forward each legislative session, and as currently codified it recognizes federal changes through December 31, 2025 — after OBBBA, so the restored 100% bonus flows through.
This is TIME-SENSITIVE BY CONSTRUCTION — not just a general risk. The statute (W. Va. Code §11-21-9(a)) states directly that no federal amendment made on or after January 1, 2026 may be given any effect for West Virginia purposes until the legislature affirmatively moves the cutoff date forward. This verdict must be re-checked after each West Virginia legislative session.
On a representative West Virginia single-family rental (the single-family rental band we publish, 9–32% of depreciable basis reclassified, 16% representative), the reclassified components alone generate an estimated $18K–$165K of federal Year-1 depreciation — roughly $6,660–$61,570 of Year-1 tax savings at the 37% top bracket, flowing through on the current West Virginia return.
Federal vs West Virginia, Side by Side
For an individual investor's or West Virginia business's cost-segregation-reclassified components:
| Tax provision | Federal (IRC) | West Virginia |
|---|---|---|
| Bonus depreciation under §168(k) | 100% may apply to qualified property acquired and placed in service after January 19, 2025, subject to §168(k) eligibility, related-party/prior-use, binding-contract, and election rules | Flows through today. Conformity cutoff recognizes federal changes through 2025-12-31 (W. Va. Code §11-21-9(a)), no §168(k) item on the additions list |
| Conformity mechanism | Not applicable | Static cutoff, rolled forward each session — not automatic |
| Statutory freeze on future changes | Not applicable | Explicit. No amendment made on or after 2026-01-01 may be given effect until the legislature moves the date |
| Individual vs corporate | Same §168(k) rules for both | Structurally identical — §11-21-9(a) personal, §11-24-3(a) corporate |
| Federal usability of the deduction | Subject to passive activity, at-risk, basis, and business-interest limits | Same federal limits govern the federal deduction; West Virginia adds no state-level reduction while the cutoff holds |
Source: W. Va. Code §11-21-9; IRC §168(k). Federal bonus figures reflect current law; eligibility depends on acquisition and placed-in-service dates and elections.
The freeze written into the statute, not a general risk
West Virginia's conformity works differently from a state whose reference simply might fall behind if the legislature is slow. W. Va. Code §11-21-9(a) sets a static cutoff — currently December 31, 2025 — and then states directly that no amendment made to the Internal Revenue Code on or after January 1, 2026 may be given any effect for West Virginia tax purposes until the legislature affirmatively moves that cutoff forward. It is a freeze written into the mechanism itself, not an inference about what would happen if nobody acted.
Today's answer is favorable because the current cutoff already sits after the One Big Beautiful Bill Act (OBBBA), so the restored 100% bonus depreciation is captured. But the freeze date — January 1, 2026 — is close enough to this page's publication that a reader should not treat "conforms today" as a settled, permanent fact. Any federal depreciation change enacted on or after that date will not be given effect in West Virginia until a future legislative session rolls the cutoff forward, however clearly the federal law reads otherwise.
The corporate provision at §11-24-3(a) is structurally identical, sharing the same cutoff and the same freeze language. For a property owner or CPA, the practical takeaway is to re-verify West Virginia's current cutoff date after every legislative session — not once, and not only when a federal change makes the news.
Illustrative numbers: a West Virginia single-family rental
Using the single-family residential (SFR) band we publish — 9–32% of depreciable basis reclassified into 5/7/15-year property, 16% representative — on a property priced between $250,000 and $650,000, with a 20% residential land allocation, and 100% federal bonus depreciation for eligible components under current law and West Virginia's current conformity cutoff:
| Line item | Federal | West Virginia |
|---|---|---|
| Purchase price band | $250,000–$650,000 | Same property |
| Depreciable basis (20% land allocation) | $200,000–$520,000 | Same basis |
| Reclassified to 5/7/15-yr (9–32% of basis) | $18K–$165K | Same reclassification, same components |
| Year-1 treatment | $18K–$165K deducted (100% bonus, if eligible) | Same $18K–$165K deducted — current cutoff captures it |
| Marginal tax rate | Up to 37% | West Virginia personal income tax rate (verify current year with the WV State Tax Department) |
| Illustrative Year-1 federal tax savings on reclassified components | ~$6,660–$61,570 (37% × $18K–$165K) | Same deduction reduces West Virginia taxable income today; re-verify after each session |
Figures are illustrative and use the site's published SFR reclassification band; your result depends on your basis, land allocation, bracket, component mix, and eligibility. Whether the full federal deduction is usable in the current year still depends on your passive-loss, at-risk, basis, and business-interest situation. West Virginia's conformity cutoff is set by the legislature each session and is statutorily frozen for any federal change on or after 2026-01-01 until then — confirm the current cutoff before relying on this table in a later filing year.

For a West Virginia investor or business, the depreciation workflow follows the federal figure directly while the state's conformity cutoff remains current:
- Federal Form 4562: depreciation and amortization, including the §168(k) bonus deduction on eligible reclassified components. Flows to Schedule E (rental) or Schedule C (active business).
- Schedule E (or Schedule C): the accelerated federal deduction reduces federal taxable income in Year 1, subject to the federal passive-loss, at-risk, basis, and business-interest limits.
- West Virginia income tax return: West Virginia taxable income follows federal law as amended through the state's current cutoff (2025-12-31 as codified), with no §168(k) item on the personal additions list at §11-21-12.
- Form 3115 §481(a) section: included only if this is a federal lookback method change on a property placed in service in a prior year (see below).
The reclassified schedule is the same engineered output for both books; West Virginia simply follows the federal number, contingent on the legislature keeping the cutoff date current past 2026-01-01.
Form 3115 lookback on a West Virginia property
If the property was placed in service in a prior tax year and depreciation was reported using a non-segregated method, a federal Form 3115 (Application for Change in Accounting Method) may allow a current-year §481(a) catch-up adjustment for the accelerated depreciation you missed, generally without amending prior returns. This is often the single biggest acceleration mechanism in cost segregation. Any catch-up dollars are illustrative and depend on placed-in-service date, prior depreciation claimed, bonus eligibility, land allocation, and component mix.
The federal §481(a) catch-up is the primary lever, and it remains subject to the federal passive-loss, at-risk, and basis limits. For West Virginia, the catch-up flows through to the West Virginia return the same way as an ordinary Year-1 bonus, provided the state's conformity cutoff in the catch-up year is current with the federal provision being claimed.

Should you skip cost segregation in West Virginia? No.
West Virginia's current conformity captures the full federal benefit with no add-back. The math favors doing the study, for three reasons:
- West Virginia follows the federal figure today. The cutoff currently recognizes federal changes through 2025-12-31, after OBBBA, so the restored 100% bonus flows through. How much you use in the current year still depends on your passive-loss, at-risk, basis, and business-interest situation.
- The Form 3115 lookback still captures missed federal years. If the property was placed in service in a prior year and depreciated without cost segregation, the federal §481(a) catch-up may be available, generally without amending prior returns.
- The state-tax picture is simple today. No add-back, no subtraction schedule, no manufacturing carve-out — the reclassified schedule applies identically on both returns while the cutoff holds.
The nuance to flag with your CPA is sharper here than in most conforming states: West Virginia's own statute freezes any federal amendment on or after January 1, 2026 until the legislature acts again, so a study delivered today should have its West Virginia treatment re-verified after every legislative session, not assumed to carry forward automatically.
Frequently asked
Does West Virginia allow bonus depreciation?
Yes, today. West Virginia's conformity cutoff recognizes federal changes through December 31, 2025 — after the One Big Beautiful Bill Act (OBBBA) — so an individual or business claims the restored 100% federal bonus (subject to §168(k) eligibility, related-party/prior-use, binding-contract, and election rules) and it flows through to the West Virginia return. No §168(k) item appears in the personal additions list at W. Va. Code §11-21-12.
Why does this page call West Virginia's conformity 'time-sensitive by construction'?
Because the statute itself builds in an expiration on new federal changes, not just a general risk that the legislature might fall behind. W. Va. Code §11-21-9(a) states that no amendment made to the Internal Revenue Code on or after January 1, 2026 may be given any effect for West Virginia purposes until the legislature affirmatively moves the conformity date forward again. That is a hard statutory freeze written into the conformity mechanism, not a soft assumption about legislative inaction.
Does today's favorable answer already account for that freeze?
Yes — the current cutoff (federal changes through 2025-12-31) sits just before the freeze date takes effect, and OBBBA's bonus depreciation changes were enacted before that cutoff, so they are captured. The freeze becomes relevant only for a FUTURE federal change enacted on or after 2026-01-01: until the West Virginia legislature rolls the cutoff date forward again, such a change would not be given effect on the West Virginia return, regardless of how the federal law reads.
How often does this need to be re-checked?
After every West Virginia legislative session, not once. The statute's own design depends on the legislature acting again each year to move the cutoff date forward. A session that does not do so would freeze West Virginia's federal reference at whatever date is last on the books, stranding any newer federal depreciation change. Given the freeze is dated from 2026-01-01, this is worth checking again very soon after this page's publication, not just annually in the abstract.
Do individuals and corporations get the same treatment in West Virginia?
Yes, structurally. The personal income tax provision (W. Va. Code §11-21-9(a)) and the corporate provision (§11-24-3(a)) are essentially identical in structure and share the same cutoff mechanism.
Is cost segregation still worth it in West Virginia?
Yes, today's conformity captures the full federal benefit with no add-back. A cost-segregation-reclassified component gets the same accelerated deduction on both the federal and West Virginia returns right now. The one thing worth tracking closely with your CPA — more closely than in a typical fixed-date-conformity state — is whether the West Virginia legislature has rolled the cutoff date forward past 2026-01-01 in its most recent session, given the statute's explicit freeze on anything after that date.
Can I use Form 3115 on a West Virginia property I bought years ago?
Often, yes, at the federal level. If the property was placed in service in a prior tax year and depreciation was reported using a non-segregated method, a federal Form 3115 (Application for Change in Accounting Method) may allow a current-year §481(a) catch-up for the accelerated depreciation you missed, generally without amending prior returns. Any catch-up dollars are illustrative and depend on placed-in-service date, prior depreciation, bonus eligibility, land allocation, and component mix. Because West Virginia currently conforms to federal changes through 2025-12-31, the catch-up flows through to the West Virginia return the same way it does federally — subject to the conformity cutoff remaining current in the year the catch-up is claimed.
