What’s new in West Virginia for 2026: a 5% rate cut, Social Security untaxed, and the federal breaks that never arrive

Two things change on the 2026 West Virginia return and both are good news. Every rate is 5% lower than last year, retroactive to January 1, 2026, so the top rate is 4.58% instead of 4.82% and the bottom rate 2.11% instead of 2.22%. And for the first time, Social Security is subtracted in full for every filer, regardless of income; the old $50,000 single / $100,000 joint line that decided who got the break is gone. What did not change is longer. The brackets stayed where they were. The $2,000 personal exemption stayed at $2,000. West Virginia still allows no itemized or standard deduction, which is why the new federal deductions for tips, overtime, seniors and car-loan interest make no difference on the IT-140 even though the Legislature formally adopted the federal law that created them. The 2026 return will look like the 2025 return with slightly smaller tax on every line of the schedule.

The West Virginia Tax Division is the agency; this article calls it the Department. The 2026 forms were not out when this was written, so line numbers below are from the 2025 IT-140 and its schedules, and anything the Department has not yet published for 2026 is marked.

The rate cut: S.B. 392

Senate Bill 392 passed the Legislature on March 14, 2026, was signed March 31 and took effect June 12, 2026, with the rates applying to all taxable years beginning on or after January 1, 2026. It writes a new section 11-21-4j into the Code with a schedule that is exactly 5% below the 2025 schedule at every step. The dollar brackets did not move.

Married filing separately uses the same rates on brackets half as wide: $5,000, $12,500, $20,000 and $30,000. Joint filers get no wider brackets than single filers; the schedule is the same for both.

Because the cut is 5% of the tax rather than a change to the brackets, everybody saves the same proportion. At $30,000 of West Virginia taxable income the tax is $790.50 instead of $832.50, a saving of $42; at $50,000, $1,528.50 instead of $1,609.50, a saving of $81; at $100,000, $3,782.50 instead of $3,981.50, a saving of $199. The Department revised the 2026 withholding tables (IT-100.2.A and B) to match. Paychecks from early 2026 were withheld at the old rates, and that difference comes back as a slightly larger refund.

Social Security: the phase-in ends

House Bill 4880 of 2024 set a three-year schedule for filers above the old income line. In 2024 they subtracted 35% of their federally taxable Social Security; in 2025, 65%; in 2026, 100%. Filers at or below $50,000 of federal AGI ($100,000 joint) had been fully exempt since 2022 and are unaffected. From the 2026 return on, the full amount of Social Security included in federal AGI comes off on Schedule M, line 34, for everyone.

The catch, which the Department’s own page explains, is the $8,000 senior citizen modification on Schedule M line 47. That modification, for filers 65 or older or permanently and totally disabled, is reduced dollar for dollar by the subtractions already taken on lines 29 through 34, and line 34 is Social Security. A retiree whose Social Security subtraction is $8,000 or more gets nothing further off a pension or IRA; a retiree whose Social Security subtraction is, say, $5,000 gets the remaining $3,000 against other income. The state describes the result as the higher of the $8,000 or the itemized subtractions, not both. The full Social Security subtraction is worth real money to retirees above the old line, but for many of them it also uses up the $8,000 they had been applying to a pension. The retiree article walks through it: West Virginia for retirees.

Conformity: S.B. 400 adopted the federal law, and most of it still does not reach the return

West Virginia conforms to the Internal Revenue Code as of a fixed date and moves the date forward each year. Senate Bill 400, passed February 23, 2026 and in effect from passage, amended section 11-21-9 to give effect to federal amendments made after December 31, 2024 and before January 1, 2026, which takes in the whole of the July 2025 federal tax law. Federal changes made on or after January 1, 2026 are not adopted until the Legislature acts again.

What that means in practice turns on one fact: the IT-140 starts from federal adjusted gross income. Anything that changes AGI changes West Virginia income. Anything the federal return does after AGI, which is where the standard deduction, itemized deductions and the new 2025 deductions all live, is invisible here, because West Virginia replaces the entire federal deduction stage with its own $2,000 exemptions and Schedule M.

Put another way, S.B. 400 mattered to people who run a business, farm or rental and want the same depreciation on both returns. For wage earners and retirees, the bill changed nothing they can see. The federal articles on these items are Tips, overtime and the senior deduction and The SALT cap.

2027 and the revenue trigger

S.B. 392 did a second thing that matters for planning. It rewrote the revenue trigger in section 11-21-4h. Beginning August 15, 2026, and every August 15 after, the Secretary of Revenue compares the prior fiscal year’s adjusted general revenue collections with an inflation-adjusted base of $4,293,884,754, the fiscal 2019 figure. If collections beat the base, the excess, divided by the year’s personal income tax collections and rounded down to a whole percent, becomes a further across-the-board rate cut of up to 10%. The statute says a cut applies beginning the second taxable year following the determination, which for an August 2026 determination means tax year 2028, although the same section also says its rates govern taxable years beginning on or after January 1, 2027 in place of the 4j schedule (verify how the Department reads the 2027 start against the second-year rule). Whether the August 15, 2026 check produced a cut could not be confirmed when this was written (verify). For the 2026 return none of this matters: the 2.11% to 4.58% schedule above is the law. For 2027 estimates, assume the same schedule until the Department says otherwise.

Smaller items carrying into 2026

Child and dependent care credit. West Virginia allows 50% of the federal Form 2441 credit, nonrefundable, on line 18 of the Tax Credit Recap Schedule. It was enacted in the October 2024 special session and 2025 was its first full year. The federal credit itself is larger for 2026, with a top rate of 50% of expenses, so the state match grows with it. Paper filers must attach Form 2441 or the credit is denied. The family article covers it: Credits and breaks for West Virginia families.

Original W-2s and 1099s. Since the 2025 return, paper filers must enclose original W-2s, 1099s and K-1s showing West Virginia withholding or the withholding credit is disallowed. E-filers are not affected. This stays in force for 2026.

Property tax credits by letter. The refundable Motor Vehicle Property Tax Adjustment Credit refunds county vehicle tax paid on time (first half before October 1, second half before April 1), in the amount on the MV-1 letter the Department mails each winter, on IT-140 line 21(A). In 2026 the Department said a data error marked some eligible vehicles wrong and that corrected letters were going out; anyone whose MV-1 looks low should claim the amount actually paid and attach receipts. See West Virginia calendar and forms.

New forms. The Department is rebranding from “State Tax Department” to “Tax Division” and reformatting the IT-140. The line numbers cited in these articles are the 2025 ones (verify against the 2026 forms when released).

No ballot measure. No statewide tax question was on the November 3, 2026 ballot.

What did not change. The $2,000 and $500 exemptions. The $8,000 senior and surviving-spouse modifications. The $2,000 public pension cap and the full exemption for military, police, fire, federal law enforcement and Railroad Retirement pensions. No state earned income credit, no state child tax credit. The $600 estimated-payment threshold. The income tables for the Family Tax Credit and the two senior property-tax credits are reset each year and the 2026 tables are to come.
