Alaska Income Tax Forms – Everything You Need to Know

Alaska is one of the few states in America that does not have an individual income tax. As such, there are no Alaska income tax forms to fill out for residents. However, if you are a non-resident who earns income in Alaska, you may be required to file state income taxes. In this article, we will explore everything you need to know about Alaska income tax forms, who needs to file them, and what information should be provided.

Who Needs to File Alaska Income Tax Forms?

As we mentioned earlier, Alaska does not have an individual income tax. Thus, if you are an Alaska resident, you do not have to file any state income tax forms. However, there are exceptions to this rule. If you earn income from other states, you will have to file a return in those states for the income that you earn there. For example, if you work in Seattle, Washington, but live in Alaska, you will have to file a Washington state income tax return.

Even if you don’t have to file an Alaska income tax return, you still have to file a federal income tax return. The Internal Revenue Service (IRS) is still very much interested in your income, regardless of where you earn it.

On the other hand, non-residents who earn income from Alaska must file an Alaska non-resident tax return if certain thresholds are met. According to the Alaska Department of Revenue (DOR), you must file a tax return if your gross income from Alaska sources is more than $12,000 annually.

What Income is Taxable in Alaska?

Alaska does not tax individual income. However, we do have a state corporate income tax and unemployment insurance tax.

The corporate income tax is imposed on the net income of any corporation operating in Alaska or receiving income from Alaska sources. For a corporation doing business in Alaska but not incorporated in Alaska, income that is earned and taxed in another state is excluded from Alaska taxation.

Unemployment insurance tax in Alaska is more commonly referred to as “unemployment tax.” Alaska employers are required to pay unemployment insurance on the first $43,000 of an employee’s wages in a calendar year. The tax rate varies depending on the employer’s industry, employment history, and other factors.

What Forms Do Non-Residents Need to File?

If you are a non-resident who earned income in Alaska, you will need to fill out Form 611. This form is for non-residents who received income from Alaska sources and are required to pay taxes on that income. It is important to note that Alaska defines “Alaska sources” as any income from services performed in Alaska, income from property located in Alaska, or income from a business, trade, or profession operating in Alaska.

Generally speaking, if you work in Alaska, you will likely have to file Form 611. This can be true whether you work for an Alaska-based company or not. Additionally, if you own an interest in an Alaska partnership or S Corporation, you may need to file Alaska non-resident income tax. The income from these entities passes through to the owner, and if it has Alaska source income, a non-resident owner must file.

Form 611 is relatively straightforward to complete. The form is available on the Alaska DOR’s website, and it requires you to provide basic information such as your name, address, social security number, and the amount of income earned from Alaska sources. The Alaska DOR provides detailed instructions for Form 611 to ensure accurate and expedient completion.

When to File Alaska Income Tax Forms

For Alaska non-residents who earned income from Alaska sources and are required to pay taxes on that income, tax returns must be filed by April 15th of the following year. For example, if you received income from Alaska in 2021, you would need to file your tax return by April 15, 2022. However, if April 15th falls on a weekend or holiday, the due date will be pushed back to the next business day.

Extensions are available for non-residents who cannot file by the deadline. If you need more time, you can request an automatic six-month extension by filing Form 4868-AK. This extension gives you until October 15th to file your return, but it does not give you more time to pay your taxes.

Consequences of Not Filing Alaska Income Tax Forms

If you are a non-resident who earned income from Alaska sources and does not file the appropriate tax forms, you could be subject to penalties and interest charges. Additionally, failure to file or pay Alaska income taxes could result in legal action by the Alaska Department of Revenue. The state can also intercept any future refunds of overpaid state income taxes to satisfy unpaid tax debts.

It’s also worth noting that Alaska tax authorities share information with other states. If you don’t file an Alaska non-resident tax return, the state can inform other states where you may owe taxes, and the tax bill can follow you wherever you go.


In conclusion, individual income is not taxed in Alaska, and residents are not required to file Alaska income tax forms. However, non-residents who earned income in Alaska may have to file Alaska non-resident income tax returns. Typically, this is any nonresident earning more than $12,000 from Alaska sources a year. If you are required to file, make sure you file your Alaska tax return on time to avoid penalties and interest charges. By knowing what taxes apply and how to file, non-residents working in Alaska can fulfill their tax obligations and focus on successfully growing their careers and businesses.
