What the New York Form ST-810 (March-May 2025) Is For
New York Form ST-810 (March-May 2025) is a specialized quarterly sales and use tax return intended for businesses classified as part-quarterly filers in New York State. These businesses are required to file when their taxable receipts and purchases are subject to use tax and exceed $300,000 in any quarter. Unlike quarterly filers who file once every three months, part-quarterly filers must file monthly advance payments on Form ST-809 and reconcile them using Form ST-810 at the end of the sales tax quarter.
When You’d Use New York Form ST-810 (March-May 2025)
- You’re a part-quarterly filer: Businesses that exceeded $300,000 in taxable sales or use-taxable purchases in any previous quarter are required to file using this form at the end of the following quarter.
- You’re reconciling Form ST-809 advance payments: This form consolidates estimated sales tax payments made in March and April and finalizes the quarter’s reporting.
- You’re filing late or amending: If you're correcting errors from an earlier submission or missed the June 20 deadline, this is the required form to submit, along with any applicable penalties or interest.
- You’re closing or restructuring a business: Final returns for business closures, changes in ownership, or structural shifts must be filed using Form ST-810, accompanied by the appropriate final return indicators.
Key Rules or Details for 2025
Understanding the rules for New York Form ST-810 (March-May 2025) is critical to staying compliant with state sales tax regulations:
- Part-quarterly thresholds: If your total taxable sales or use-taxable purchases reach $300,000 in any quarter, you must begin part-quarterly filing the next quarter and continue until you drop below the threshold for four consecutive quarters.
- MCTD surcharge: For sales delivered into the Metropolitan Commuter Transportation District, an additional 0.375% local tax must be applied and reported accurately by the jurisdiction.

- Advance payment requirement: You must file Form ST-809 and make estimated tax payments for March and April before submitting Form ST-810 for the full quarter.
- Destination-based sourcing: New York sales tax is calculated based on the location where goods are delivered, rather than the location from which they are shipped, making it crucial to apply the correct jurisdictional rates.
