Georgia sales tax is due by the 20th day of the month after your reporting period ends. A monthly filer’s January tax is due February 20; a quarterly filer’s January–March tax is due April 20; an annual filer’s return for the year is due the following January 20. Miss the date and the state adds a 5 percent penalty for every 30 days late, up to 25 percent, plus 9.75 percent annual interest for 2026.
The 20th-of-the-Month Rule
Every Georgia sales and use tax return is due no later than the 20th day of the month following the end of the reporting period, whether you file monthly, quarterly, or annually.
- Monthly filers: the return for each calendar month is due by the 20th of the following month. Tax collected in March 2026 is due April 20, 2026.
- Quarterly filers: returns are due April 20, July 20, October 20, and January 20.
- Annual filers: the return covering the calendar year is due by January 20 of the following year.
If the 20th lands on a Saturday, Sunday, or Georgia state holiday, the deadline moves to the next business day. For paper returns, the postmark counts as the filing date. For electronic returns, your submission has to be complete by the end of that deadline day.
Which Deadline Applies to You
The Georgia Department of Revenue assigns your filing frequency. For the first six months after you register, you file monthly no matter how little tax you collect.
After that, you can submit a written request to switch to quarterly or annual filing if your liability is small enough. The Commissioner has authority under O.C.G.A. § 48-8-49 to approve or deny the change. Dealers who consistently owe around $200 or less each month are the typical candidates for a less frequent schedule; most businesses stay monthly.
Frequency isn’t permanent. If a quarterly filer’s revenue climbs, the Department can move them back to monthly. A monthly filer whose sales fall off can ask to move to quarterly.
What You Lose by Filing Late
Georgia pays you a small amount for filing on time. When your return and payment both arrive by the deadline, you keep 3 percent of the first $3,000 in combined state and local sales and use tax reported on each certificate of registration number, plus 0.5 percent of anything above that. You calculate the dealer’s compensation directly on the return and it reduces what you send in.
A late return or late payment forfeits the discount entirely. For higher-volume sellers, the 0.5 percent on amounts above $3,000 adds up across a year, which is a direct dollar reason to file on schedule even before any penalty enters the picture.
Penalties for Missing the Deadline
Georgia’s late-filing penalty escalates in 30-day steps:
- First 30 days late: 5 percent of the unpaid tax, or $5, whichever is greater.
- Each additional 30-day period (or any part of one): another 5 percent or $5, whichever is greater, while the failure continues.
- Maximum: 25 percent of the unpaid tax, or $25, whichever is greater.
A dealer who can show the failure was due to “providential cause,” meaning circumstances genuinely beyond their control, can ask for a waiver of these penalties. A false or fraudulent return triggers a separate, additional penalty. All of this sits on top of the tax you still owe.
Interest on What You Owe
Interest runs on any sales tax not paid by the due date. Georgia sets the rate each calendar year using the bank prime loan rate plus 3 percentage points. For 2026 the rate is 9.75 percent per year, accruing monthly.
Interest starts the day after the due date and continues until you pay in full. It cannot be waived, regardless of the reason for the late payment. On a $5,000 balance, 9.75 percent annual interest runs about $40 a month, stacking on whatever penalty has already been assessed.
How to File by the Deadline
Georgia uses Form ST-3 for sales and use tax. You report gross sales, subtract exempt sales, and calculate tax on the remainder, with separate lines for state and local tax based on where the sale is sourced.
If you owe more than $500 on any return, you must file and pay electronically through the Georgia Tax Center. Once you cross that threshold on any single return, electronic filing is required going forward even if a later return falls below $500. Payment is made by ACH debit; save the confirmation number as proof of filing and payment. Businesses that owe $500 or less may still file on paper, though the Department of Revenue encourages electronic filing because it is free and reduces errors that can trigger a review.
Your return isn’t considered timely until both the filing and the payment are complete by the deadline, so leave enough margin for the bank debit to go through.
