What Is the New York Form ST-810 (September–November 2018) For?
New York Form ST-810 (September–November 2018) is a quarterly sales and use tax return used by part-quarterly (monthly) filers in New York State. It reconciles the advance payments made through monthly filings (Form ST-809) with the business’s actual tax liability for the full quarter. The form is required to maintain sales tax compliance with NY rules and must be submitted even if no tax is due for the period.
When You’d Use New York Form ST-810 (September–November 2018)
Businesses should file this form in the following scenarios:
- Regular filing requirement: This form must be filed by businesses that exceeded $300,000 in taxable sales, purchases, or rentals during the quarter and submitted Form ST-809 for each month.
- Late filing scenarios: If the December 20, 2018, deadline is missed, the form should still be filed as soon as possible to reduce penalties and interest, which begin accruing immediately.
- Amended returns: If errors are found after submitting the original return, an amended version must be filed with corrected information and supporting documentation.
- Final Returns: If a business closes, changes its legal form, or sells its operations during the quarter, it must file a final Form ST-810, reporting all tax activity through the final date of business operations.
Key Rules or Details for 2018
Several vital rules explicitly applied to the 2018 filing period:
- Filing frequency threshold: Businesses must continue monthly filing until taxable sales fall below $300,000 for four consecutive quarters.
- Electronic filing rules: Most businesses must web file if they prepare their own returns using a computer with internet access, as part of the sales tax compliance requirements under the new rules.
- Jurisdiction-based reporting: Sales must be reported based on the delivery destination, not the seller's location, to comply with destination-based tax rules.
- Special solar energy rules: Some cities continued to impose local taxes on certain residential and commercial solar sales, despite general exemptions, which required special notation on the form.
- Credit documentation: Any credits claimed on the return must be supported by Form ST-810-ATT and a separate Form AU-11 with detailed backup.
- Recordkeeping requirement: Businesses are required to retain records supporting their NY sales tax return for at least three years from the filing or due date.
Step-by-Step (High Level)
Filing New York Form ST-810 (September–November 2018) involves the following steps:
- Step 1 - Return Summary: Enter your business information and gross sales for the quarter, including taxable, exempt, and nontaxable amounts, and check any applicable boxes, such as credits or final return.
- Step 2 - Final Return Information: Complete this section only if the business has closed or changed its legal form. Provide the closure date, sale information, and successor details if applicable.
- Step 3 - Sales and Use Tax Calculations: For each jurisdiction where sales occurred, enter taxable sales and purchases subject to tax, and apply the correct tax rate to determine the tax due.
- Step 4 - Special Taxes: Report applicable receipts from passenger car rentals and telecommunication services using the specific rates required by law.
- Step 5 - Credits & Advance Payments: Enter monthly payments made via Form ST-809 and PrompTax, and list credits such as overpayments carried forward.
- Step 6 - Final Tax Due: Add total taxes, subtract credits and payments, and determine if an additional fee is required or if an overpayment exists.
- Step 7 - Penalty & Interest: If filing after the deadline or paying less than required, calculate applicable penalty and interest using official guidance.
- Step 8 - Total Due: Enter the amount due or overpayment. If submitting payment, ensure the check includes the sales tax ID and the period covered.
- Step 9 - Sign & Mail: Sign the return, include a third-party designee if desired, and mail the completed return and attachments to the designated address if not filing online.
Common Mistakes and How to Avoid Them
Several filing errors occur frequently and can be prevented with the proper procedures:
- Wrong jurisdiction reporting: Always report sales in the jurisdiction where the buyer received the goods or services, not where your business is located.
- Not filing with no tax due: File the return even if there were no taxable sales or purchases to avoid the automatic $50 penalty.
- Missing credit documentation: Do not claim credits without also submitting Forms ST-810-ATT and AU-11 along with all supporting documents.
- Mixing gross and taxable sales: Only report taxable sales in jurisdiction-specific lines and exclude sales tax from those amounts to avoid overpayment.
- Forgetting monthly payment reconciliation: Include all advance payments from Form ST-809 and PrompTax in Step 5 to avoid double-paying.
- Using outdated rates or forms: Always verify you are using the correct version of Form ST-810 and the applicable tax rates for the filing period.
- Skipping special schedules: Attach all required supplemental schedules for specific types of sales, even if some pages are blank.
What Happens After You File
Once you file New York Form ST-810 (September–November 2018), the New York State Department of Taxation and Finance processes your return and payment. Returns are reviewed using automated checks against monthly filings, credit card data, and past return history. If your return shows an overpayment, the amount can be carried forward or refunded by filing Form AU-11. Underreported or inconsistent filings may trigger audits, especially if sales data or jurisdiction codes do not align. Amendments filed before audit selection may reduce penalties.
