Wyoming for retirees: nothing on the income, and half off the house at 65

A Wyoming retiree owes the state nothing on Social Security, a pension, an IRA or 401(k) withdrawal, a Roth conversion, an annuity, interest, dividends or a capital gain, because Wyoming has no income tax at any level. There is no form that asks. The federal return is the whole return, and the IRS taxes a retiree in Sheridan exactly as it taxes the same person in Minneapolis. So the Wyoming questions for a retiree are not about income. They are about the house: whether the owner-occupied affidavit got filed for the 25% exemption, whether the household is 65 with 25 years of Wyoming property tax behind it (in which case the 50% exemption is the better deal and the owner has to choose), and whether income is low enough for the Property Tax Refund Program, which hands back up to three-quarters of last year’s bill by the end of September.

The other Wyoming question is federal. With no state tax to think about, some retirees stop thinking about withholding altogether. The custodian takes nothing, the pension takes nothing, and April arrives with a federal balance and an underpayment penalty. Wyoming removed the state problem; it did not remove the federal one.

What is not taxed, and what still is

The federal items that bite a retiree bite the same in Wyoming. Up to 85% of Social Security is taxable once provisional income (AGI plus tax-exempt interest plus half of Social Security) passes $32,000 joint or $25,000 single, thresholds that have never been indexed. The $6,000-per-person senior deduction for 2025 through 2028 phases out above $150,000 of modified AGI joint, $75,000 single. And Medicare’s IRMAA surcharge, set two years in arrears, starts for 2026 premiums at 2024 modified AGI above $218,000 joint and $109,000 single; a large Roth conversion or a home sale with gain above the exclusion in 2026 shows up in the 2028 Part B and Part D premiums. None of these has a Wyoming counterpart to soften it, because there is no Wyoming return to soften anything on.

Roth conversions are the strategy the no-tax state makes cheaper. A conversion in a state with a 5% income tax costs 5% more than the same conversion in Wyoming. A retiree who arrived from a taxing state in 2026 can do the conversions that were put off because of the state tax at the federal cost alone, and the federal cost is what it always was: the bracket, the Social Security formula and IRMAA two years later. The planning is in The Roth IRA guide.

Withholding and estimates: the federal problem Wyoming leaves alone

A retiree who moved here should give every pension administrator and IRA custodian a new Form W-4P (periodic payments) or W-4R (one-time withdrawals) with the state election set to none, because the custodian keeps withholding for the state on file until told otherwise. Old-state tax withheld after the move comes back on that state’s part-year return, but only if the return is filed.

Federal withholding is the other half. Federal estimated payments are owed when the balance after withholding will be more than $1,000, and the safe harbors, 100% of last year’s tax or 90% of this year’s, with 110% of last year’s above $150,000 of AGI, apply in Wyoming as everywhere. The simplest fix for a household living on Social Security, an IRA and a brokerage account is withholding on the RMD: a December withdrawal with enough federal tax withheld counts as if it had been paid evenly through the year. The mechanics are in Estimated payments.

What Wyoming gives seniors instead: the house

Wyoming’s retiree benefits are on the property tax bill, handled by the county assessor and the county treasurer, and they stack in a particular order.

At any age: the 25% homeowner exemption. 25% of the fair market value of the home and its improved land, on the first $1,000,000 of value, for an owner who lives there at least eight months of the year. From tax year 2026 the owner must file an owner-occupied affidavit with the county assessor, through the Department of Revenue’s online notification or at the assessor’s office. The 2026 deadline was March 1; the 2027 deadline is to come. A snowbird who winters in Arizona for five months still qualifies; one who is gone five months and a week does not.

At 65, with 25 years of Wyoming property tax: the 50% long-term homeowner exemption. An owner or spouse 65 or older who has paid Wyoming residential property tax for 25 years or more, not necessarily on the same house, and lives in the home eight months a year can exempt 50% of fair market value on the first $3,000,000, under 2026 HB 45. The claim goes to the county assessor by March 1 each year from 2027 (the 2026 deadline was the fourth Monday in May); after the first year a phone call or letter to the assessor by March 1 confirming nothing has changed keeps it. A surviving spouse keeps it. A home cannot take both this and the 25% exemption, so the owner chooses, and 50% beats 25% on any house under $3,000,000. The 2027 sunset that was in the original 2024 act is repealed; the exemption is now permanent law.

At any age, under the income limit: the Property Tax Refund Program. A refund of up to 75% of the prior year’s property tax on the primary residence, capped at one-half of the county’s median residential tax bill, for a household that has lived in Wyoming five years, lived in the home nine months of the year and paid the tax on time. The full refund goes to a household with income at or below 125% of the greater of the county or statewide median household income; a household between 126% and 145% gets 65% of it; above 145%, nothing. In most counties the 145% ceiling for the 2026 program was about $114,043 of household income (verify), which puts the full-refund line near $98,000 (verify); Teton and a few other counties sit higher. Household assets other than the home, one vehicle per adult and retirement accounts must be under an indexed limit, $150,000 per adult in the statute (verify current indexed figure). The deadline is the first Monday in June (June 1, 2026); refunds are paid between July 1 and September 30; the 2026 program averaged $771.35 per household on $12,000,000 of funding. The Legislature must fund it each session, so the 2027 program is to come.

Veterans. $6,000 of assessed value a year, about $420 at 70 mills, for honorably discharged veterans of World War II, Korea or Vietnam, veterans with a campaign or expeditionary medal from a foreign armed conflict, and veterans with a VA-rated compensable service-connected disability; three years of Wyoming residency; unremarried surviving spouses qualify; renewed every year by the fourth Monday in May, and the unused balance can be applied to the vehicle registration. Details and the other programs are in Property-tax relief in Wyoming.

The old state cannot follow the pension

Federal law since 1996 (4 U.S.C. §114) bars any state from taxing the retirement income of a person who is no longer its resident, however the pension was earned. A thirty-year Colorado schoolteacher who retires to Laramie owes Colorado nothing on the PERA pension from the day she stops being a Colorado resident. The same protection covers IRA and 401(k) withdrawals and most deferred compensation paid over ten years or more. What the old state keeps is everything with a source there: rent from a house kept behind, a business still operating there, wages for days worked there, and the gain on old-state property sold after the move. And the old state decides whether the person has really left. Its residency test is what matters, and the test is in Moving to Wyoming.
