NYS-45 bulk upload filers: two things to get right before you submit

If your organization files NYS-45 wage data through the Web Upload application, two procedural details have a bigger-than-expected impact on whether your submission goes through cleanly: how you report NYS-1 prepayments, and what you do if an electronic payment fails.

Neither issue is complicated — but getting either one wrong can result in bills, filing error notices, or payment processing problems. Here's what to know

Note: This information is for informational purposes only and does not constitute formal tax, legal, or compliance advice. Always consult with qualified tax advisors, legal counsel, and your organization’s internal teams for guidance specific to your situation. Additional regulations may apply. For the most accurate and up-to-date information, refer to official government resources and regulatory agencies.

Report only the prepayments you've already made

How do I report NYS-1 prepayments on the NYS-45?

When reporting NYS-1 prepayments for a specific quarter, include only those prepayments submitted before uploading your NYS-45 wage data. Do not include payments that haven't been submitted yet. If you owe a balance at the time of your NYS-45 wage data upload, pay it with your NYS-45 submission.

The rule is straightforward: your prepayment total should reflect only what you've already paid — not what you plan to pay. Reporting a payment that hasn't been submitted yet will create a mismatch in the Tax Department's records.

Important: Incorrectly reporting your NYS-1 prepayments may result in receiving a bill from the Tax Department.

What to do if your NYS-45 electronic payment fails

If a payment submitted via the Pay from bank account feature fails, do not resubmit through the Web Upload application. The correct path is to send a replacement check.

Important: Submitting a second upload file instead of sending a replacement check will cause processing errors and may result in filing error notices.

How to send a replacement check for a failed NYS-45 payment

What should I do if my NYS-45 Web Upload payment fails?

Do not resubmit through the Web Upload application. Instead, send replacement checks by mail — one for unemployment insurance and one for withholding tax. Include the upload confirmation number and the confirmation page with each check. Overnight delivery is recommended.

Send your replacement checks and upload confirmation page together so the Tax Department can match your payment to the previously uploaded file.

  • Write checks for the original amounts owed: one for unemployment insurance, one for withholding tax.
  • Write the upload confirmation number and NYS Employment Contributions and Taxes on each check or money order.
  • Include a copy of your upload confirmation page. Find it in your Online Services account message center. If it's been deleted, call 518-485-6654 for assistance.
  • Mail your replacement checks and confirmation page promptly. Overnight delivery is recommended.

Frequently asked questions

What happens if I incorrectly report my NYS-1 prepayments?

Reporting prepayments that haven't been submitted yet — or omitting ones that have — creates a mismatch in the Tax Department's records. The likely result is a bill from the Tax Department.

Why can't I just resubmit my payment through Web Upload after a failure?

Resubmitting through the Web Upload application causes processing errors and may trigger filing error notices. When the original Pay from bank account payment fails, the Tax Department requires a replacement check — not a second electronic submission.

What if I can't find my upload confirmation page?

Your confirmation page is available in your Online Services account message center. If it's been deleted, contact the Tax Department at 518-485-6654 to obtain a copy before mailing your replacement check.

Do I need to send separate checks for unemployment insurance and withholding tax?

Yes. Write two separate checks — one for unemployment insurance, one for withholding tax — each for the original amount owed. Both should include the upload confirmation number and NYS Employment Contributions and Taxes.
