About Filing Deadlines
Quarterly Filing: Most states require quarterly sales tax filings, due on the last day of the month following the end of each quarter (April 30, July 31, October 31, January 31).
Monthly Filing: High-volume sellers (typically over $100K/year in tax collected) may be required to file monthly, due on the 20th or last day of the following month depending on the state.
Annual Filing: Some low-volume sellers may qualify for annual filing, typically due January 31 of the following year.
Filing frequencies and deadlines vary by state. Always check your specific state requirements. Some states have different deadlines for different filing frequencies.
State-Specific Information
Filing deadlines and frequencies vary by state and seller volume. Visit your state's revenue department website or consult with a tax professional for specific requirements.
