Tax landscape for small businesses
Alaska figures here come from the Alaska Department of Revenue, Tax Division. Federal figures come from the IRS. Every figure names its page and the date it was checked or last updated.
On personal income, the Alaska Tax Division's personal income tax page (Alaska, checked October 31, 2026) says "The State of Alaska currently does not have an individual income tax, therefore no employee withholding for state income tax is required." On sales, the Tax Division's sales and use tax page (Alaska, checked October 31, 2026) says "The State of Alaska currently does not have a sales and use tax; however, some local jurisdictions impose local sales taxes."
For local rates, the Tax Division (Alaska, checked October 31, 2026) points to "Alaska Taxable", published by the Department of Commerce, Community and Economic Development, which it calls "an overview of each community, whether it collects taxes, and if it does, its tax rates."
Corporations are a separate case. The Tax Division's corporate income tax page (Alaska, checked October 31, 2026) says "Alaska levies a corporate income tax on Alaska taxable income which is based on federal taxable income with certain Alaska adjustments." It adds "The 0% rate applies to taxable income of $25,000 and below, while the 9.4% rate applies to taxable income of $222,000 and over."
Worked example, with sample figures: a C corporation with $20,000 of Alaska taxable income falls under the Tax Division's sentence (Alaska, checked October 31, 2026) "The 0% rate applies to taxable income of $25,000 and below", so its Alaska corporate income tax is $0.00 (20,000 x 0%). Federal tax is separate.
Tax overview
Each row lists a tax area and its notes. Confirm current figures with your state's tax agency or the IRS.
| Tax type | Rate or basis | Notes |
|---|---|---|
| Individual income tax | "does not have an individual income tax" | The Alaska Tax Division's personal income tax page (Alaska, checked October 31, 2026). The page also says "no employee withholding for state income tax is required". |
| State sales and use tax | "does not have a sales and use tax" | The Tax Division's sales and use tax page (Alaska, checked October 31, 2026): "some local jurisdictions impose local sales taxes". |
| Corporate income tax | "from 0% to 9.4%" | The Tax Division's corporate income tax page (Alaska, checked October 31, 2026): "The 0% rate applies to taxable income of $25,000 and below, while the 9.4% rate applies to taxable income of $222,000 and over." |
| Federal estimated tax, corporations | "$500 or more" | The IRS estimated taxes page (In the US (federal), last reviewed or updated September 25, 2026): "Corporations generally have to make estimated tax payments if they expect to owe tax of $500 or more when their return is filed." |
Filing requirements
This list isn't a complete checklist for your business.
Alaska corporate income tax payment
The Tax Division's corporate income tax page (Alaska, checked October 31, 2026) says "Payment of the Alaska tax must be made on or before the 15th day of the fourth month after the close of the tax year." It adds "The payment due date cannot be extended."
Alaska corporate income tax return
The same page (Alaska, checked October 31, 2026) says "Tax returns are due 30 days after the federal return due date." It also says "If the federal return is on extension, the Alaska return is automatically on extension."
Corporations with income in more than one state
The Tax Division's corporate income tax page (Alaska, checked October 31, 2026) says "Multistate corporations apportion income on a water's edge basis using the standard apportionment formula of property, payroll and sales." The worked example above starts from Alaska taxable income and doesn't show apportionment. Ask a tax professional how it applies to your corporation.
Alaska corporate estimated payments
A Tax Division notice dated August 15, 2024 (Alaska, checked November 1, 2026) says "Alaska adopts the Internal Revenue Code by reference, including the requirement to make quarterly estimated payments of corporate income tax." The same notice says an exemption for certain corporations under AS 43.20.012(a)(3) "expired on July 1, 2023", and that "a prior-year liability of zero is not a safe harbor for failure to make estimated payments". The notice is from 2024, so ask the Tax Division whether newer guidance applies.
Local sales tax
The Tax Division's sales and use tax page (Alaska, checked October 31, 2026) says "some local jurisdictions impose local sales taxes". Check with the community where you sell, or ask a tax professional. This guide doesn't confirm how sellers outside a community collect its sales tax; ask the community before you sell into it.
Federal self-employment tax
The IRS self-employment tax page (In the US (federal), last reviewed or updated October 30, 2026) says you file Schedule SE when, among other cases, "Your net earnings from self-employment (excluding church employee income) were $400 or more."
Deductions and write-offs
Confirm with your state how it treats each item.
- Self-employment tax deduction: the IRS self-employment tax page (In the US (federal), last reviewed or updated October 30, 2026) says "This deduction only affects your income tax. It does not affect either your net earnings from self-employment or your self-employment tax."
- Choosing a record system: the IRS recordkeeping page (In the US (federal), last reviewed or updated May 1, 2026) says "You may choose any recordkeeping system suited to your business that clearly shows your income and expenses."
- Corporate taxable income (Alaska): the Tax Division's corporate income tax page (Alaska, checked October 31, 2026) describes Alaska taxable income as "based on federal taxable income with certain Alaska adjustments". Ask a tax professional which adjustments apply to you.
Practical tips
- Find out whether your community collects sales tax before you set a rate on your invoices.
- Watch the corporate payment date. The Tax Division (Alaska, checked October 31, 2026) says "The payment due date cannot be extended."
- Sort costs by category. Billed's expense tracking page (checked October 31, 2026) says "Billed's expense report can group your expenses by category."
- Hand reports to your accountant. The same page says "Reports can be filtered by date range and exported for your accountant, bookkeeper or tax software."
- Confirm these figures with the Tax Division and the IRS before you file.
