How often do I file sales tax returns in Arkansas?

Arkansas assigns filing frequency based on your expected tax liability: monthly for high-volume sellers, quarterly for mid-volume, annually for low-volume. The DOR may reassign as your activity changes.

What if I had zero sales in Arkansas for a period?

You still file a zero return. Missing filings trigger penalties regardless of tax owed. Most tax services file zero returns automatically.

When are Arkansas sales tax returns due?

Typically the 20th of the month following the filing period (with variations). Late filing and late payment each carry their own penalty structure — file early to avoid either.

If your Filing business sells $100,000 or 200 transactions into Arkansas in a calendar year, you have economic nexus and must register, collect, and remit Arkansas sales tax.

Filing frequency in Arkansas

Most states assign a filing cadence when you register, based on your expected tax liability: monthly for high-volume sellers ($50K+ tax liability/year), quarterly for mid-volume, and annually for low-volume. Arkansas may reassign your frequency if your liability changes materially.

Zero returns still matter

Even if you had zero taxable sales in Arkansas during a period, you must file a zero return. Missing filings trigger penalties regardless of tax owed. Most automated tax services will file zero returns for you by default.

Due dates

Arkansas's filing due dates are typically the 20th of the month following the period end (with variations). Late filing penalties are usually 5%/month up to 25%; late payment adds interest. Register for the state's auto-pay or use a service that remits on your behalf to avoid late fees.

Filing mistakes that cost Arkansas sellers

Skipping a zero return in a slow month — most penalty exposure comes from missed filings, not unpaid tax.
Waiting until due date to file; Arkansas's portal can time out on volume days. File at least 48 hours early.
Not keeping exemption certificates on file — if you're audited and can't produce a valid certificate for a tax-exempt sale, that sale becomes taxable and you owe the uncollected tax.

Arkansas nexus note

Arkansas sales tax nexus and economic nexus threshold: beginning July 1, 2019 under Act 822, remote sellers and marketplace facilitators must collect Arkansas state and local sales and use tax when sales of tangible personal property, taxable services, digital codes, or specified digital products delivered into Arkansas exceed $100,000 or 200 transactions in the current or previous year. Arkansas is a Streamlined Sales Tax member state, and the Arkansas DFA remote-seller page says the same threshold applies to marketplace facilitators.
