Alaska for retirees: the dividend, the federal lines that still bite, and the $150,000 property tax exemption

A retired couple in Alaska pays no state tax on Social Security, pensions, IRA and 401(k) withdrawals, military or government retirement, Roth conversions, interest, dividends or capital gains, because Alaska has no individual income tax. The couple also receives two Permanent Fund Dividends, $2,400 in 2026, and that is where the federal return takes notice: the dividend is ordinary income on Schedule 1, line 8g, it counts in the formula that decides how much Social Security is taxable, and it counts in the income that sets Medicare premiums two years later. On the other side of the ledger, the first $150,000 of assessed value of the couple’s home is exempt from municipal property tax once either spouse is 65, on a single application to the local assessor. For most retired Alaskans, those three things, the dividend, its federal ripples, and the exemption, are the whole subject.

The simplicity is real. There is no state return, no state withholding to stop, no state estimated payment, and no state credit or exclusion to qualify for. A retiree’s tax year in Alaska is Form 1040, the property tax bill, and the dividend application between January 1 and March 31.

What is not taxed, and what the federal return still does

Alaska’s estate tax statute is written to equal the federal credit for state death taxes, and that credit no longer exists, so no Alaska estate tax has been owed for years and no Alaska estate return is filed.

The federal return does not change because the address is in Alaska. Social Security is taxed by the same formula, RMDs begin at the same age, the standard deduction is the same, and the $6,000-per-person senior deduction for 2025 through 2028 applies the same way. What is different is that there is nothing underneath it: no second return that follows the federal one, and no state tax to deduct on Schedule A, which is why few Alaska retirees itemize.

Where the dividend shows up

The dividend is small next to a pension, but it is income, and several federal calculations run on income.

Taxable Social Security. The share of Social Security that is taxed depends on provisional income: adjusted gross income without Social Security, plus tax-exempt interest, plus half the benefits. For a joint return, benefits start becoming taxable above $32,000 and reach the 85% ceiling above $44,000. A couple in that window pays tax on the dividend twice over: on the $2,400 itself, and on the additional Social Security the $2,400 drags into income. Fifty cents of benefit becomes taxable for each dollar of provisional income in the lower band, and 85 cents in the upper one, so $2,400 of dividend can make up to $2,040 more of Social Security taxable. A couple whose provisional income is already past $44,000 is at the ceiling and feels only the $2,400.

Medicare premiums. The income-related adjustment to Part B and Part D premiums, IRMAA, is set from modified adjusted gross income two years back; the 2026 premium depends on the 2024 return, and the 2028 premium will depend on the 2026 return being filed now. The first threshold for 2026 is $109,000 single and $218,000 joint. The dividend counts. A couple a few hundred dollars under the line in a year with a large IRA withdrawal can be put over it by $2,400 of dividends, and the premium increase lasts a full year.

Withholding. Nothing is withheld from the dividend unless the name and Social Security number on the application failed the IRS match in May, in which case 24% is withheld and the Division cannot return it; it comes back as a credit on Form 1040. Nothing is withheld for Alaska from a pension or IRA, because there is nothing to withhold. A retiree who moved to Alaska from a state with an income tax should check the state box on every 1099-R and file a new Form W-4P with the custodian if the old state is still being withheld; the money comes back only on that state’s return.

Federal estimates. With no state tax to pay, the federal side is the only one to plan for, and a household living on Social Security, an IRA and a brokerage account with no withholding on any of it will owe an underpayment penalty in April unless it pays estimates or has tax withheld from the IRA. The simplest fix is to have the IRA custodian withhold enough from the December RMD to cover the year; withholding is treated as paid evenly through the year no matter when it comes out.

Roth conversions while an Alaska resident

A Roth conversion is taxed by the federal government in the year of the conversion and by the state of residence, if it has an income tax. In Alaska the second part is zero, which makes the state the cheapest place a person will ever live to convert. The federal cost is what it always is, and the usual planning applies: convert enough each year to fill the current bracket without spilling into the next, watch the IRMAA thresholds two years out, and remember that a conversion raises provisional income and can make more Social Security taxable in the conversion year. A retiree who expects to leave Alaska for a state with an income tax has a reason to convert before the move; one who plans to stay has no state reason to hurry, only the federal bracket arithmetic.

The dividend is a small complication here too. Because it is ordinary income, it takes up $1,200 per person of whatever bracket room the conversion is meant to fill. A couple filling the 12% bracket to its 2026 top of $100,800 has $2,400 less room than the pension and Social Security figures alone suggest.

The 180-day rule and the retiree who winters elsewhere

The dividend has a residency test, and it is the one state rule that reaches a retiree’s travel plans. To receive the 2027 dividend a person must have been an Alaska resident for all of 2026 and intend to remain indefinitely, and may have been absent from the state for no more than 180 days in 2026 for any reason. Absences beyond 180 days are allowed only for the reasons the statute lists: continuous medical treatment or convalescence, but not if the reason is the climate; caring for a seriously ill family member; settling a close relative’s estate, up to 220 days; active-duty military service; full-time education; and a short list of others. A retiree who spends November through April outside Alaska for the weather is at about 180 days and has to count carefully. One who spends seven months south has lost the dividend for the following year, and after five straight years of absences over 180 days the Division presumes residency itself is gone.

Absences totaling 90 days or more in the year must be reported on the application, and the Division wants proof of travel in the applicant’s name, boarding passes rather than itineraries. Registering to vote elsewhere, claiming a residency-based property tax break elsewhere, or filing a resident income tax return in another state ends Alaska residency for the dividend regardless of the day count.

The property tax exemption has its own occupancy rule. Anchorage and the Mat-Su Borough require, after the first year, that the home be owned and occupied as the primary residence for at least 185 days before January 1, and that it not be rented or leased to anyone while the owner is away. A snowbird who stays under the dividend’s 180 absent days is over the property tax’s 185 present days; the two rules are written to agree.

The property tax exemption

The exemption is statutory and mandatory: every municipality that levies a property tax must exempt the first $150,000 of assessed value of the primary residence of an owner 65 or older, a veteran with a service-connected disability of 50% or more, or the surviving spouse, 60 or older, of someone who qualified. In Anchorage the application is due March 15 and the owner must have been 65 by the previous December 31 and an Alaska resident for the whole of the previous year; in Mat-Su the deadline is April 30 and the same residency rule applies. Once granted it renews each year without a new application unless something changes, and the owner is required to report a change in ownership, occupancy or residency. The Office of the State Assessor reported an average exempted value of $139,393 and an average tax saving of $1,965 for 2017, the most recent figure on its page.

Municipalities may add to it. Mat-Su exempts up to $135,279 more for the same owners under its optional program; Anchorage grants every owner-occupant, senior or not, a residential exemption of 40% of assessed value up to $75,000. Which exemptions exist, and how they combine, is a question for the local assessor; the mechanics and the deadlines are in Property tax relief in Alaska. Many Alaska retirees live where there is no property tax at all, and for them the exemption is moot.
