What Is the New York Form ST-810 (September–November 2020) For?
New York Form ST-810 (September-November 2020) is a quarterly sales tax reconciliation form used by businesses classified as part-quarterly filers. These businesses file monthly sales and use tax returns (Form ST-809) during each month of the quarter, then use Form ST-810 to summarize and reconcile the total activity. The form applies specifically to the third quarter of 2020, covering the period from September 1 through November 30. It consolidates all taxable sales, exemptions, jurisdiction-based taxes, credits, and advance payments into one return.
When You’d Use New York Form ST-810 (September-November 2020)
Businesses must file this form under several specific circumstances:
- High-volume companies: You must file this return if your combined taxable receipts, purchases subject to tax, rents, and amusement charges totaled $300,000 or more in any quarter.
- Motor fuel distributors: You are required to file this form if your business sold 100,000 gallons or more of motor fuel or diesel during the quarter.
- Late Filing: You must file this return if you missed the original December 21, 2020, deadline; however, penalties and interest may apply depending on the extent of the late submission.
- Final return: You are required to submit this return within 20 days of your last business day if your business permanently closed during or shortly after the third quarter.
- Jurisdiction correction: If you reported sales under the wrong jurisdiction, you must correct the figures in your next scheduled return using this form rather than filing an amended version.
This form is typically used as part of the quarterly sales tax reconciliation process for businesses with monthly reporting obligations.
Key Rules or Details for the 3rd Quarter of 2020
Several compliance requirements applied to New York Form ST-810 (September-November 2020):
- Electronic filing requirements: Businesses subject to the Web File mandate were required to file this return through the Business Online Services portal unless specifically exempt.
- Precise jurisdiction reporting: You must report taxable sales and use tax by the jurisdiction where the delivery occurred, not the location of your business.
- MCTD tax: An additional tax of 0.375% applied to sales within the Metropolitan Commuter Transportation District, which includes New York City and surrounding counties.

Step-by-Step (High Level)
Completing New York Form ST-810 (September-November 2020) follows a structured process that reconciles monthly sales and use tax filings into a single quarterly sales tax return:
- Step 1 - Return summary: You must report total gross sales from all New York locations and out-of-state sales delivered into New York, including taxable, nontaxable, and exempt transactions.
- Step 2 - Final return information: You must complete this step only if the filing is a final return due to business closure, sale, or a change in entity status.
- Step 3 - Tax calculation by jurisdiction: You must enter taxable sales and purchases subject to tax for each applicable jurisdiction using the correct jurisdiction codes and rates.
- Step 4 - Special taxes: You must calculate any applicable special taxes, including passenger car rental taxes, vapor product taxes, and applicable service-related taxes.
- Step 5 - Credits and advance payments: You must report credits and all advance payments made during the quarter, including your three monthly sales and use tax payments.
- Step 6 - Tax due calculation: You must combine the totals from the prior steps to determine the total tax due for the quarter.
- Step 7 - Penalties and interest: You must calculate penalties and interest if the return is filed late or if the full amount of tax was not paid on time.
- Step 8 - Final Amount Due: You must add any penalties and interest to the tax to determine the total payment required.
- Step 9 - Signature and submission: You must sign the return, include preparer information if applicable, and submit the form with payment to the New York State Department of Taxation and Finance.
This process ensures accurate reconciliation of monthly sales and use tax filings into a single quarterly reporting period.
Common Mistakes and How to Avoid Them
Errors on this part of the quarterly tax return often result in notices, delays, or additional assessments:
- Failing to file all pages: You should always submit all four pages of the return, along with any required schedules, even if some pages contain minimal information.
- Using incorrect jurisdiction codes: You should verify that all jurisdiction codes and tax rates match the September–November 2020 filing period before completing the form.
- Misreporting gross sales: You should report total gross sales in Step 1 and separately identify nontaxable sales rather than entering only taxable amounts.
- Claiming unsupported credits: You should file Form AU-11 with complete documentation when claiming credits instead of adjusting taxable sales directly.
- Mathematical errors: You should carefully transfer subtotals between pages to ensure all column totals are accurate.
- Omitting marketplace provider information: You should complete the marketplace reporting section if you facilitated third-party sales during the quarter.
- Missing the final return deadline: You should file within 20 days of your last business day when submitting a final return to avoid penalties.
A careful review of each section helps prevent errors commonly associated with a quarterly tax return.
What Happens After You File
After you submit New York Form ST-810 (September-November 2020), the New York State Department of Taxation and Finance reviews the return for accuracy, verifies jurisdiction allocations, and matches advance payments against the total tax due.
