Alaska has no statewide sales tax. Sales-tax obligations arise under the rules of individual boroughs and cities, and remote sellers may have to collect for local jurisdictions that have adopted the single-level remote seller code. The Alaska Remote Seller Sales Tax Commission (ARSSTC) coordinates that system through the ARSSTC portal; it does not turn Alaska into a state with one statewide sales tax.
If you have received an audit notice, do not ignore it or assume that a filing with one local government resolves every issue. The notice, the jurisdictions involved, your sales and exemption records, and the applicable local rules determine what to do next. Sales Tax Compliance USA is a people-led, done-for-you service for ecommerce and cross-border sellers. We can help organize the records, review the tax treatment and filings, and prepare a response; the right position depends on your circumstances and should be checked against the current ARSSTC requirements.
How Alaska’s local sales tax system works
Alaska is a home-rule state: local jurisdictions administer their own sales taxes. There is no statewide sales tax rate or single statewide tax that applies everywhere. A borough or city may impose local sales tax, and the tax rules and rates can differ by jurisdiction.
The ARSSTC provides a coordinated system for remote sales into participating jurisdictions that have adopted the single-level remote seller code. The code establishes common rules for covered remote sellers, while the tax collected is associated with the local jurisdictions where the sale is sourced. A sale delivered to a place without a participating local tax does not automatically become taxable just because it was delivered somewhere in Alaska. Check the destination and current jurisdiction rules rather than applying one assumed Alaska-wide rate.
Understand Alaska’s economic nexus threshold
The ARSSTC states that a remote seller meets the statewide economic threshold when gross sales of property, products, or services delivered in Alaska meet or exceed $100,000 in the current or previous calendar year. The threshold is statewide, not a separate $100,000 test for each borough or city. The Commission’s current seller information says the threshold is based on gross sales, including sales through a marketplace facilitator.
Meeting the threshold does not mean every Alaska destination imposes tax, nor does it establish that every transaction is taxable. It can create a registration and collection obligation for sales into jurisdictions that have adopted the uniform code. Marketplace-only sellers may be treated differently under the code. Because marketplace arrangements, sales channels, and local participation can affect the analysis, confirm your facts and the current rule with the ARSSTC before deciding whether to register or collect.
Register to collect Alaska local sales tax
Remote sellers who meet the ARSSTC threshold and make sales into participating jurisdictions should review the Commission’s registration requirements and use the ARSSTC portal. Registration is with the Commission’s coordinated remote-seller system; it is not a general Alaska statewide sales-tax permit. Keep a copy of the registration confirmation and the information used to identify your business, sales channels, and Alaska activity.
Before registering, map your Alaska deliveries to their destinations and distinguish direct sales from marketplace sales. Confirm whether the jurisdictions where you sell participate in the code and whether an exception applies to your business. If you are unsure whether your sales meet the threshold or how a marketplace arrangement is treated, ask the ARSSTC or have a compliance professional check the current requirements rather than relying on an assumed rule.
File local sales tax returns on time
Registered sellers must file the returns required by the ARSSTC and report the relevant sales and tax for the jurisdictions covered by the filing. The Commission’s seller information describes monthly filing as the usual schedule, with a different schedule possible when arranged with the Commission. Do not assume that a zero-tax period means no return is required; follow the filing instructions assigned to your account.
Use the due date and filing frequency shown in your current ARSSTC account or notice, because the applicable schedule and current requirements should be confirmed directly. Reconcile marketplace reports, order data, refunds, exemptions, and tax collected before filing. If a return is late or a payment is missing, address it promptly and contact the Commission about the account-specific balance and any available process. Do not rely on a penalty or interest figure without checking the current official rule.
Respond to an Alaska sales tax audit notice
Read the notice carefully and record its response date, the periods under review, the jurisdictions involved, the records requested, and the auditor’s contact details. The ARSSTC uniform code makes covered remote sellers and marketplace facilitators subject to audit, and the Commission may examine business records to determine whether the correct tax was collected and remitted. A municipality may also have authority under its own local law; the notice should identify who is conducting the examination and under what authority.
Respond by the stated deadline, even if you need to ask for clarification or additional time. Preserve relevant records and avoid changing or deleting source data. Ask the auditor to clarify broad requests, the format for delivery, and how to submit sensitive information securely. Keep a dated copy of every submission and communication. If the notice is unclear or the requested period appears inconsistent with your records, get help before making assumptions or agreeing to an adjustment.
Prepare the records auditors may request
An audit may review records needed to determine the amount of tax due. These can include sales ledgers, order-level transaction data, invoices, receipts, customer and delivery addresses, shipping records, marketplace statements, payment processor reports, general-ledger entries, filed returns, and proof of tax payments. Auditors may also ask for exemption certificates or other documentation supporting exempt sales, along with records explaining refunds, cancellations, discounts, and adjustments.
Organize the records by reporting period and destination jurisdiction, and make sure totals can be traced from source transactions to filed returns and payments. For cross-border sellers, retain the underlying order and fulfillment information that explains where goods were shipped and how the transaction was recorded. The ARSSTC code requires suitable sales and supporting records; the exact documents requested depend on the audit and the issues being examined.
How long should Alaska sales-tax records be kept?
The ARSSTC uniform code states that covered remote sellers and marketplace facilitators must preserve suitable sales records, exemption support, and other necessary books and records for three years from the date of the return reporting the sales. This is the Commission code’s stated retention period for sellers within its scope.
Do not destroy records simply because three years have passed if an audit, protest, local requirement, or other legal obligation is still open or may apply. Local rules and the facts of a particular matter can affect what should be retained. Keep records long enough to resolve open filings and disputes, and confirm the applicable retention rule with the ARSSTC or the relevant municipality if your business is subject to a separate local requirement.
Challenge an assessment and address tax, penalties, and interest
If you disagree with an audit result or estimated assessment, compare the proposed adjustment with your transaction-level records, filed returns, payments, destination data, and exemption documentation. Identify each disputed item and explain the correction you believe is supported, with records that allow the auditor to verify it. Do not treat an informal discussion as a formal protest unless the notice or governing procedure confirms that it preserves your rights.
The ARSSTC code provides a written protest process for disputing an audit or examination result or an estimated tax notice. The Commission’s code states a 30-calendar-day period from the date of the notice to file the protest. Check the notice and current code immediately, follow the required submission method, and retain proof of timely delivery. If an assessment is upheld, additional tax may be due along with any applicable penalties and interest under the governing rules. The amount and available relief depend on the facts and current requirements; verify them with the Commission rather than assuming a particular calculation or waiver.

Frequently asked questions
Does Alaska have a statewide sales tax?
No. Alaska has no statewide sales tax. Sales-tax obligations may instead arise under the rules of individual boroughs and cities, including participating jurisdictions using the ARSSTC single-level remote seller code.
Can Alaska cities and boroughs impose sales tax?
Yes. Local jurisdictions can impose sales tax, and Alaska is a home-rule state in which local jurisdictions administer their own taxes. Rates, taxable transactions, and local requirements can vary, so check the destination jurisdiction and whether it participates in the ARSSTC system.
Can a municipality audit a business’s sales-tax records?
A municipality may have audit authority under its own local law, while the ARSSTC code also makes covered remote sellers and marketplace facilitators subject to Commission audits. Read the notice to identify the auditing authority, jurisdictions, periods, and legal basis, and confirm any uncertainty with the issuing authority.
What records can be reviewed during a sales-tax audit?
An auditor may review sales and accounting records needed to determine tax liability, such as transaction data, invoices, delivery and shipping records, marketplace statements, filed returns, payment records, and exemption documentation. The precise request depends on the audit issues and the authority conducting it.
How long should sales-tax records be kept?
The ARSSTC uniform code states that covered sellers must preserve suitable sales records, exemption support, and other necessary records for three years from the date of the return reporting the sales. Keep records longer when an audit or dispute remains open, or when a separate local requirement may apply, and confirm the rule for your circumstances.
How can a business protest a sales-tax audit result?
The ARSSTC code provides for a written protest of an audit or examination result or an estimated tax notice, and states a 30-calendar-day period from the notice date. Follow the notice and current code for the required method and contents, support each disputed item with records, and retain proof of timely submission.
What happens if an audit finds additional sales tax due?
The authority may issue an assessment for additional tax, and applicable penalties and interest may also be charged under the governing rules. Review the calculation against your records, pay or formally dispute the amount as appropriate, and act by the deadline in the notice; the exact balance and any available relief depend on the facts and current rules.
