Alaska Estate Tax: What Families Need to Know in 2026

You're settling an estate in Alaska and someone told you to watch out for estate taxes. Here's the short answer: Alaska itself has no estate tax. The state stopped collecting one in 2005. And the federal exemption — which for years was forecast to be cut in half in 2026 — was instead raised and made permanent. If you are working from advice given before July 2025, the number you have in mind is almost certainly wrong.

Alaska Has No State Estate Tax

Alaska is one of 38 states that imposes neither a state estate tax nor an inheritance tax. The Alaska Department of Revenue eliminated its state estate tax in 2005, and there has been no legislative movement to reinstate it. For the personal representative of a modest or mid-sized Alaskan estate, this means one entire layer of tax complexity simply does not exist.

Practically speaking, this simplifies the settlement process considerably. You do not need to file a state estate tax return with Alaska, and no Alaska state tax authority has a claim against the estate's assets based on the decedent's death.

The 2026 Federal Exemption: $15 Million

Between 2018 and 2025, the Tax Cuts and Jobs Act (TCJA) provided historically high federal estate and gift tax exemptions — $13.61 million per individual in 2024, rising to $13.99 million in 2025. Those amounts were scheduled to expire at the end of 2025 and fall back to roughly $7 million, and for several years that looming cut drove a great deal of estate planning advice.

It did not happen. The One Big Beautiful Bill Act, signed on July 4, 2025, set the federal basic exclusion amount at $15 million per individual for deaths and gifts in 2026, indexed for inflation in later years. There is no scheduled sunset. A married couple can shield $30 million with a portability election.

For high-net-worth Alaskan families — particularly those with significant real estate, commercial fishing operations, aircraft, or Native Corporation stock — this removes a deadline that many plans were built around. The federal estate tax rate remains 40% on the amount exceeding the exemption.

If the estate you are settling was planned around a $7 million post-sunset threshold, that plan was built on an assumption that no longer holds. Bypass trusts and other structures designed to capture exemption before it disappeared may now be doing work that is no longer needed, which is worth raising with a tax professional.

What This Means for Alaska Estates Specifically

Alaska has several asset classes that affect the tax calculation in ways that are not always obvious.

Alaska Native Corporation (ANCSA) shares are federally protected and inalienable. Under Alaska Statute 13.16.705, ANCSA settlement common stock is explicitly excluded from the state probate estate, and its value is not counted when calculating the overall estate value or determining statutory allowances. This exclusion also applies to the federal estate tax calculation for inalienable shares — but the rules here are technically complex, and a tax attorney or CPA familiar with ANCSA law should be consulted for any estate holding these shares.

Real property in Alaska, including land, residential properties, and commercial real estate, is included in the gross estate for federal tax purposes at fair market value as of the date of death. Property values in Anchorage, Fairbanks, and particularly the Mat-Su Valley have appreciated substantially over the past decade, so it is worth getting a defensible date-of-death valuation even when the estate looks comfortably under $15 million.

Bureau of Indian Affairs (BIA) restricted allotments and Native allotments pass through a separate federal BIA probate process, not state probate. The treatment of these assets for federal estate tax purposes is governed by federal law and requires specialized guidance — this is not territory to navigate without professional help.

Statutory Allowances Reduce the Taxable Estate

Before the estate tax calculation even begins, Alaska law allows the personal representative to claim three specific allowances that reduce the estate's net value. These take priority over virtually all creditor claims:

• Homestead Allowance (AS 13.12.402): $27,000 for a surviving spouse, or divided equally among minor and dependent children if there is no surviving spouse.
• Family Allowance (AS 13.12.404): Up to $18,000 for the surviving spouse and minor children during estate administration.
• Exempt Property (AS 13.12.403): Up to $10,000 in household furniture, automobiles, appliances, and personal effects for the surviving spouse.

These allowances are indexed for inflation and collectively can shield up to $55,000 in estate value from creditor claims. For federal estate tax purposes, these are relevant to the extent they reduce the net estate available for distribution to heirs.

Practical Steps for the Personal Representative

If the estate you are administering appears to be within striking distance of the $15 million federal threshold, the following steps are worth taking immediately:

1. Get a preliminary valuation. You cannot know whether federal estate tax applies without knowing the fair market value of all assets as of the date of death. The Personal Representative is required by Alaska law to file an Inventory of Property (Form P-370) with the court within three months of appointment — this document establishes the starting point.

2. Consult a CPA or estate tax attorney before distributing assets. If a federal estate tax return (IRS Form 706) is required, it is due nine months after the date of death. Distributing assets before that return is filed and any tax paid can create serious liability for the Personal Representative.

3. Do not assume a pre-2025 plan is still calibrated correctly. If someone did estate planning based on a $12–13 million exemption, or on the expectation that it would be halved in 2026, that plan needs to be revisited against the current $15 million threshold.

4. Verify whether any portability election should be filed. If the deceased was married, the surviving spouse may be able to "port" any unused portion of the deceased spouse's federal exemption. This requires filing IRS Form 706 even if no estate tax is owed — and it must be filed on time.

What About Smaller Estates?

For estates well below the $15 million federal threshold — which describes the overwhelming majority of Alaskan estates — federal estate tax is simply not a factor. The settlement process focuses entirely on state procedures: probate court filings with the Alaska Superior Court, the Small Estate Affidavit (Form P-110) for qualifying estates, vehicle title transfers through the DMV, and the Alaska Permanent Fund Dividend estate application.

The complete settlement process for those estates — from the first 48 hours through final distribution — is covered in the Alaska Estate Settlement Guide.

The Bottom Line

Alaska's complete absence of a state estate tax is a genuine advantage, and the federal exemption is now $15 million per person with no scheduled cliff. If the estate you are managing involves significant real estate, business interests, or investments, verify the gross estate value against the current ~$7 million federal threshold before assuming taxes are not an issue. For the majority of Alaskan families dealing with modest estates, the estate tax question has a simple answer: it does not apply. The harder parts of settling an Alaskan estate lie elsewhere — in the probate court timelines, the PFD deadlines, and the unique rules governing Native Corporation shares.
