Specific instructions

Has your address or business information changed?

If you need to update your sales tax mailing address, call the Sales Tax Information Center (see Need help?) or enter your correct address on Form ST-100. You may also use Form DTF-96, Report of Address Change for Business Tax Accounts, to update your mailing address, physical address, or designated preparer or filing service address.

You can get these forms from our website or by phone. See Need help?.

No tax due?

You must file a return even if you have no taxable sales, purchases, or credits to report. To complete a no-tax-due quarterly return:

1. Complete Step 1.
2. Write none in boxes 12, 13, and 14 in Step 3 on page 3.
3. Complete Step 9.

If you file your no-tax-due return late, we will charge you a $50 penalty.

Is this your final return?

If you have permanently discontinued your business, mark an X in the box and complete Step 2.

Are you claiming any credits?

As a registered vendor, you can claim a credit for sales tax you overpaid, paid by mistake, or collected but then repaid to your customers. You can apply the credit to reduce the tax you owe on your sales tax return.

If you are claiming credits on this return or any schedules:

1. Mark an X in the box and enter the amount of credits claimed.
2. Complete and submit Form ST-100-ATT, Quarterly Schedule CW, with this return.
3. Complete Form AU-11, Application for Credit or Refund of Sales or Use Tax, and mail it to the address in the instructions with documentation to substantiate your claim.

Exceptions

This does not apply to:

• credits reported in Step 5 of Form ST-100 (credit for prepaid tax on cigarettes or overpayment being carried forward from a prior period); or
• credit for prepaid tax on fuel reported in Step 6 of Form ST-100.10, Quarterly Schedule FR.

Step 1: Return summary

Gross sales and services

In box 1, enter the total taxable, nontaxable, and exempt sales and services from:

• your New York State business locations, and
• locations outside New York State delivered into the state, including those facilitated for marketplace sellers. 

Do not include:

• sales tax, or
• sales from Form ST-100.10.

Nontaxable sales

In box 1a, include all sales not subject to tax, whether or not an exemption document was required from the purchaser.

Example: A grocery store sells both taxable and nontaxable items, such as canned fruit. No exemption document is required from the purchaser because canned fruit is an exempt food item. The store includes the amount from these sales of canned fruit in this figure.

Example: An auto parts store sells oil filters to a repair shop. The repair shop issues Form ST-120, Resale Certificate, to the auto parts store. The auto parts store includes the amount from these sales of oil filters in this figure.

Step 2: Final return information

You must file a final sales tax return if you:

• cease business operations;
• sell, transfer, or assign your business; or
• change the entity type of your business, such as from a sole proprietorship to a corporation (note: this requires registration of the new entity, in addition to filing a final return for the old entity).

After receiving your final return, we will inactivate your sales tax account.

If you discontinue your business and do not file a final tax return, we may bill you for penalties for failing to file tax returns, which could lead to collection activities.

For more information, see Tax Bulletins Filing a Final Sales Tax Return (TB-ST-265) and Amending or Surrendering a Certificate of Authority (TB-ST-25) or visit www.tax.ny.gov (search: bulletins).

Business sold or discontinued

If you are closing your business, mark an X in the box that most closely matches the reason why. If none of them are appropriate, mark an X in the Other box and enter a brief description of the reason you are filing a final return.

If you intend to sell your business or its assets, you must give the purchaser a copy of Form TP-153, Notice to Prospective Purchasers of a Business or Business Assets. You must also collect any sales tax due on the sale of your business assets and remit it with your final return. 

Business form changed

If you are changing your entity type (for example, you were a sole proprietor and you are now changing to a partnership), you must:

• file a final return, as if you were selling or transferring your business;
• apply for a new Certificate of Authority at least 20 days before the change in business form takes place (Certificates of Authority are not transferable); and
• file Form AU-196.10, Notification of Sale, Transfer, or Assignment in Bulk, with the Tax Department at least 10 days before the change takes place. 

Step 3: Calculate sales and use taxes

If you are filing Form ST-100.13, Quarterly Schedule E, enter the amount from box 1 of that schedule in box 2a on page 2 of this return.

In Column D, do not include:

• purchases of property or services purchased for resale,

Step 5: Other tax credits and advance payments

Credit for prepaid sales tax on cigarettes

Enter your credit for prepaid sales tax on cigarettes, if any, in Column K.

Overpayment being carried forward from a prior period

If you filed a return for a prior period that had a negative balance due, and you submitted a Form AU-11 that we already approved, enter the amount you would like to claim as a credit on this return.

Advance payments

Enter the total amount of any advance payments you reported and paid with Form ST-330, Sales Tax Record of Advance Payment.

Total tax credits, advance payments, and overpayments

Add Column K and enter the total in box 16. Also enter the box 16 amount in Step 6.

Step 6: Calculate taxes due

1. Enter the amounts from box 14, Column totals; box 15c, Total special taxes and fees; and box 16, Total tax credits, advance payments, and overpayments in the appropriate spaces.
2. Add boxes 14 and 15c, then subtract box 16.
3. Enter the result in box 17.

Step 7: Calculate vendor collection credit or pay penalty and interest

Vendor collection credit

The Tax Law provides you with a credit equal to 5% of the taxes and fees reported on your return. The paper carryout bag reduction fee is not included when calculating the vendor collection credit. The maximum vendor collection credit you can claim on your return is $200.

You can receive this credit only if you file your return on time and pay the full amount due. If you file on time but do not pay the full amount due, or if you file late, you cannot claim this credit. Enter 0 in box 18 and go to Step 7B.

If you qualify, calculate your vendor collection credit in Step 7A. If the result is less than $200, enter the result in box 18. If the result is equal to or more than $200, enter only $200 in box 18.

Determine penalty and interest

If you are filing your return late, not paying the full amount due, or both, you owe penalty and interest, and cannot claim a vendor collection credit. Penalty and interest are calculated on the amount due, which you can find in box 17, Taxes due. The minimum penalty for late filing is $50. For penalty information, see Penalty computation. Interest is due on any late payment or underpayment and accrues from the due date of the return to the date the tax is paid. Interest rates are compounded daily and adjusted quarterly.

You can estimate your penalty and interest by using our Penalty and Interest Calculator (visit www.tax.ny.gov and search: penalty), or you may call the Sales Tax information Center to have a Tax Department representative estimate your penalty and interest for you (see Need help?). Enter this amount in box 19.

Penalty computation

For failure to file a return on time with no tax due, the penalty is $50.

For failure to file a return on time with tax due, the penalty is:

• for 1 through 60 days late, 10% (0.1) of the tax due for the first month plus 1% (0.01) of the tax due for each month thereafter, but in no instance less than $50.
• for 61 or more days late, the greater of:
  • 10% (0.1) of the tax due for the first month plus 1% (0.01) of the tax due for each month thereafter, not to exceed 30% (0.3); or
  • the lesser of $100 or 100% (1.0) of the tax due, but not less than $50.

For failure to pay tax, even when the return is filed on time, the penalty is 10% (0.1) of the tax due for the first month, plus 1% (0.01) of the tax due for each additional month, up to 30% (0.3).

Step 8: Calculate total amount due

If you were eligible for and claimed the vendor collection credit in Step 7, subtract the box 18 credit amount from box 17 (Taxes due) and enter the result in box 20.

If you are filing late and you entered penalty and interest in box 19, add box 19 to box 17 (Taxes due) and enter the result in box 20.

If you are not claiming the vendor collection credit and not entering penalty and interest, enter the box 17 amount as your Total amount due in box 20.

Amount paid

In box 21, enter the amount you are paying with this return, which should match the amount due in box 20.

We will charge you penalty and interest if you do not pay the total amount due.

Payment information

Make your check or money order payable in U.S. funds to New York State Sales Tax.

On your check or money order, write:

• your sales tax identification number,
• ST-100, and
• the last day of the filing period shown on the front of this return.

Enclose your payment with Form ST-100 to ensure it is credited correctly to your account.

Fee for payments returned by banks

The law allows the Tax Department to charge a $50 fee when a check, money order, or electronic payment is returned by a bank for nonpayment. However, if an electronic payment is returned as a result of an error by the bank or the department, the department will not charge the fee. If your payment is returned, we will send a separate bill for $50 for each return or other tax document associated with the returned payment.

If the total amount due is an overpayment

If the total amount due is an overpayment, you may either apply for:

• a credit to claim on your next return, or
• a refund.

To apply for a credit on your next return or a refund, you must:

• file Form AU-11, or
• if the overpayment is for prepaid sales tax on motor fuel or diesel motor fuel sold at retail, file:
  • Form FT-949, Application for Refund of Prepaid Sales Tax on Motor Fuel Sold Other Than at Retail Service Stations;
  • Form FT-950, Application for Refund of Prepaid Sales Tax on Motor Fuel Sold at Retail Service Stations;
  • Form FT-1007, Application for Refund of Prepaid Sales Tax on Highway Diesel Motor Fuel Sold at Retail Service Stations; or
  • Form FT-1010, Application for Refund of Prepaid Sales Tax on Diesel Motor Fuel Sold Other Than at Retail Service Stations.

Do not attach the refund application (Form AU-11; AU-12; FT-949 or FT-950; FT-1007 or FT-1010) to your return. You must file the application separately and mail it to the address on that form.

Step 9: Sign and mail this return

Third-party designee

If you want to authorize a friend, family member, or any other person (third-party designee) you choose to discuss this sales tax return with the New York State Tax Department, mark an X in the Yes box in the Third-party designee area of your return. Also, enter the designee’s name, phone number, email address, and any five-digit number the designee chooses as their personal identification number (PIN). If you want to authorize the paid preparer who signed your return to discuss the return with the Tax Department, enter Preparer in the space for the designee’s name. You do not have to provide the other information requested. If you mark the Yes box, you are authorizing the Tax Department to discuss with the designee any questions that may arise during the processing of your return. You are also authorizing the designee to:

• give the Tax Department any information that is missing from your return;
• call the Tax Department for information about the processing of your return or the status of your payment(s); and
• respond to certain Tax Department notices that you shared with the designee about math errors and return preparation. The notices will not be sent to the designee.

You are not authorizing the designee to bind you to anything (including any additional tax liability), or otherwise represent you before the Tax Department.

If you want the designee to perform those services for you, you must file Form POA-1, Power of Attorney, making that designation with the Tax Department. Copies of statutory tax notices or documents will only be sent to your designee if you file Form POA-1.

The third-party designee authorization cannot be revoked. However, the authorization only includes the tax period covered on this return. You may designate the same representative, or another representative, on future returns.
