What the New York Form ST-809 (2017) Is For
New York Form ST-809 (2017) is the monthly sales and use tax return required for businesses classified as part-quarterly filers in New York State. The form is used to report state and local sales tax collected and use tax owed for a single month within a quarterly filing period. It applies when combined taxable sales and purchases subject to use tax reach the required thresholds under New York's sales and use tax rules. The form supports interim reporting before quarterly reconciliation.
When You’d Use New York Form ST-809 (2017)
This form is used in specific monthly filing situations tied to sales volume and filing status under New York State tax law.
- Meeting the monthly filing threshold: Businesses must file this form when combined taxable sales and purchases subject to use tax reach $300,000 or more during any quarter, which triggers part-quarter sales tax filing requirements.
- Reporting the first two months of a quarter: Monthly filers use this form to report sales and use tax for the first and second months of each quarter before completing quarterly sales filing using Form ST-810.
- Filing during months with no taxable activity: The form must still be filed, even if no taxable sales or purchases occur during the month, to avoid late-filing penalties.
- Submitting late monthly returns: Businesses that miss the filing deadline must submit the original monthly return as soon as possible, rather than waiting for the quarterly reconciliation to be completed.
Key Rules or Details for 2017
Several filing and calculation rules apply specifically to New York Form ST-809 (2017) and must be followed to remain compliant with New York State requirements.
- Mandatory electronic filing requirements: Most monthly filers are required to file electronically using the Sales Tax Web File when preparing their own returns, using a computer to calculate tax, and having broadband Internet access.
- Long method and short method eligibility: Filers must use the long method unless they have filed returns for each of the four quarters immediately preceding the current month, which is required to qualify for the short process.
- Monthly filing status continuation rules: Businesses must continue filing monthly until taxable sales fall below $300,000 for four consecutive quarters and the New York State Department of Taxation and Finance approves a return to quarterly filing.
- Exclusion of motor fuel tax prepayments: Motor fuel and diesel motor fuel sales tax prepayments must not be reported on this form because they are filed separately on Form FT-945 or Form FT-1045.
- Credit documentation requirements: Any credits claimed that are not tied to a specific jurisdiction must be fully substantiated with supporting schedules and written explanations to avoid disallowance.
Step-by-Step (High Level)
The steps below outline how monthly filers complete and submit this form at a high level without replacing the official instructions.
- Confirm the required calculation method: Businesses must determine whether the long method or short method applies based on prior filing history and eligibility rules set by the New York State Department of Taxation and Finance.
- Complete the applicable calculation section on the form: Filers enter gross sales, taxable receipts, and purchases subject to use tax or calculate one-third of the comparable prior-year quarter, depending on the method used.
- Apply credits and advance payments correctly: Any allowable credits for prepaid sales tax or advance payments must be entered in the appropriate sections and supported by records.
- Calculate penalty and interest if required: Late filings or underpayments require calculating penalty and interest using the department’s published rates or online calculator.
- Review authorization and signature requirements: The return must be signed by an authorized individual, and third-party designee or paid preparer information must be completed when applicable.
- Submit the return and payment by the due date: Filers must submit the return electronically through Sales Tax Web File or by mail if paper filing is permitted.
Common Mistakes and How to Avoid Them
The issues below frequently lead to penalties or processing delays, but they can be avoided with careful review before submission.
- Failing to file a no-tax-due return: Businesses should always file the monthly return by the due date, even when no taxable sales occur, to avoid the mandatory late filing penalty.
- Using the short method without meeting eligibility requirements: Filers should confirm that returns were filed for the four prior quarters before selecting the short process.
- Including motor fuel tax prepayments on the form: Businesses should report motor fuel and diesel motor fuel prepayments only on the designated fuel tax forms rather than on this return.
- Submitting incomplete returns or missing identification information: Filers should include all required pages and ensure the sales tax identification number appears on each page.
- Claiming credits without documentation: Businesses should attach clear written explanations and calculations for any credits claimed to prevent disallowance.
What Happens After You File
After submission, the New York State Department of Taxation and Finance processes the return and applies the payment to the business’s sales tax account. Electronic filers receive confirmation through the Sales Tax Web File, while paper filers experience longer processing times. Monthly filings are later reconciled on the quarterly return, which reports detailed sales by locality. Records should be retained for audit purposes for the required retention period, as discrepancies may result in follow-up correspondence or review.
FAQs

The form reports obligations for sales and use tax in New York at both the state and local jurisdiction levels applicable to the sale.
Can a business return to quarterly filing after becoming a monthly filer?
A business may request a return to quarterly filing only after taxable sales fall below the threshold for four consecutive quarters and approval is granted.
