New York employers must file Form NYS-1 within three or five business days after any payroll that brings cumulative quarterly withholding to $700 or more, and must file Form NYS-45 quarterly by April 30, July 31, October 31, and January 31. Those two deadlines govern the entire withholding cycle for a New York employer, and missing either one triggers penalties that stack and can attach personally to the people running the business.1New York State Department of Taxation and Finance. Withholding Tax Filing Requirements
When Form NYS-1 Is Due
Form NYS-1 is the remittance voucher you use to send withheld tax to the state between quarterly returns. The clock starts the moment your accumulated withholding for New York State, New York City, and Yonkers combined reaches $700 within a calendar quarter. From the payroll date that crosses that line, you have either three or five business days to file NYS-1 and pay.2New York State Department of Taxation and Finance. Instructions for Form NYS-1 Return of Tax Withheld
Which window applies depends on your historical volume. Employers required to remit $15,000 or more in withholding tax during the calendar year that precedes the previous calendar year get three business days. Everyone below that threshold gets five. Educational organizations and health care providers get five business days regardless of prior-year volume under Tax Law Section 674.3New York State Senate. New York Tax Law 674 – Employers Return and Payment of Withheld Taxes
Two timing wrinkles catch employers off guard. If you run more than one payroll in a single week, you don’t need to file NYS-1 until after the last payroll of that week, even if an earlier payroll pushed you past $700. And when a calendar quarter ends between payrolls, any accumulated withholding of $700 or more must be remitted after the final payroll of that quarter.3New York State Senate. New York Tax Law 674 – Employers Return and Payment of Withheld Taxes
If your total withholding stays under $700 for the entire quarter, you skip NYS-1 for that quarter and simply pay the balance with your quarterly NYS-45.1New York State Department of Taxation and Finance. Withholding Tax Filing Requirements
When Form NYS-45 Is Due
NYS-45 is the quarterly combined return covering withholding, wage reporting, and unemployment insurance. It follows a fixed calendar:4New York State Department of Labor. NYS-45 Quarterly Reporting
- First quarter (January through March): due April 30
- Second quarter (April through June): due July 31
- Third quarter (July through September): due October 31
- Fourth quarter (October through December): due January 31
If a due date falls on a weekend or legal holiday, filing shifts to the next business day.
Every employer registered for withholding or unemployment insurance has to file NYS-45 every quarter, even in a quarter with no wages paid.4New York State Department of Labor. NYS-45 Quarterly Reporting A zero-wage quarter is not a skip quarter. If your account is open, a missed filing is a failure to file.
What You’re Actually Filing
NYS-1 is short. You report the tax withheld for New York State, New York City, and Yonkers on separate lines, add them, and pay. The form also covers withholding from pensions, annuities, retirement distributions, and certain gambling winnings, and it’s tied to your account by your Federal Employer Identification Number.2New York State Department of Taxation and Finance. Instructions for Form NYS-1 Return of Tax Withheld
NYS-45 is longer. Part A handles unemployment insurance contributions using your assigned UI rate and the state’s taxable wage base ($13,000 per employee for 2026). Part B reconciles the withholding you already remitted on any NYS-1 filings during the quarter with what you actually withheld. Part C reports individual-level data for every employee who received compensation: name, Social Security number, federal gross wages, and New York withholding.5New York State Department of Taxation and Finance. Instructions for Form NYS-45 Quarterly Combined Withholding, Wage Reporting, and Unemployment Insurance Return The Part B total must match the sum of individual withholding in Part C, and mismatches are a common audit trigger.1New York State Department of Taxation and Finance.

How to File on Time
Electronic filing is required for virtually all New York withholding returns. Paper is permitted only if you’re exempt from the mandate or the department directs you to it.6New York State Department of Taxation and Finance. Withholding Tax Filing Methods Most employers use the Department of Taxation and Finance’s Web File through the Business Online Services portal. It accepts direct entry or an upload from payroll software, calculates totals, and issues a confirmation number. Payment is authorized at submission through electronic funds withdrawal from a business account. Keep the confirmation number; it’s your proof of timely filing.
Employers whose aggregate withholding tax reported on NYS-45 for the previous year reaches $100,000 or more must participate in PrompTax, which uses electronic funds transfers on an accelerated schedule.7New York State Department of Taxation and Finance. PrompTax The state notifies you when you cross the threshold; enrollment isn’t voluntary. PrompTax filers still submit the quarterly NYS-45 on the standard calendar, but their payment mechanism and timing differ.
Penalties if You Miss the Deadline
The penalties stack, which is why the deadlines are treated as hard.
Late filing. The state adds 5% of the unpaid tax for the first month and another 5% for each additional month the return is unfiled, capped at 25%. If you’re more than 60 days late, the minimum penalty is the lesser of $100 or 100% of the tax due.8New York State Senate. New York Tax Law 685 – Additions to Tax and Civil Penalties
Late payment. Separately, late payment adds 0.5% of the unpaid tax per month, also capped at 25%. Because these run concurrently, an employer who files and pays late faces up to 5.5% per month during the overlap.8New York State Senate. New York Tax Law 685 – Additions to Tax and Civil Penalties
NYS-45 failure-to-file penalty. Skipping the quarterly return entirely carries its own penalty: the greater of $1,000 or $50 multiplied by the number of employees on your last filed NYS-45, up to $10,000. The penalty applies even when you had no wages to report, because the filing itself was required.8New York State Senate. New York Tax Law 685 – Additions to Tax and Civil Penalties
Personal Liability Behind the Deadlines
Withheld tax is treated as a trust fund held for the state, not as the employer’s own money. Every employer is personally liable for it under Tax Law Section 675, and that trust fund characterization means the obligation survives bankruptcy in ways ordinary business debts don’t.9New York State Senate. New York Tax Law 675 – Employers Liability for Withheld Taxes
If a responsible person willfully fails to collect, account for, or pay over withholding tax, the penalty equals the full amount of the unpaid tax on top of the tax itself. Responsible persons can include officers, partners, or anyone with authority over the company’s financial decisions, not just the owner.8New York State Senate. New York Tax Law 685 – Additions to Tax and Civil Penalties The federal government imposes a nearly identical trust fund recovery penalty under 26 U.S.C. § 6672, so a failure to remit both federal and state withholding can produce personal liability from both directions at once.10Office of the Law Revision Counsel. 26 U.S. Code 6672 – Failure to Collect and Pay Over Tax, or Attempt to Evade or Defeat Tax
Amending a Return You’ve Already Filed
Errors on a filed NYS-1 or NYS-45 are corrected by submitting a complete amended return through Web File. That means the whole form with all parts and all employee records, not just the lines that changed. If you filed the original electronically, Web File prepopulates the prior data so you can make targeted corrections. Submitting a partial amendment can cause processing delays and penalties.11New York State Department of Taxation and Finance. Form NYS-45 Quarterly Combined Withholding, Wage Reporting, and Unemployment Insurance Return
The Deadline When You Close the Business
If you stop paying wages permanently — through a sale, a layoff of your last employee, or a shutdown — you must file a final NYS-45 within 30 days of the date you ceased paying wages. The final return must include that date and indicate whether you sold all or part of the business. You also need to contact the Department of Labor separately about your unemployment insurance account.12New York State Department of Taxation and Finance. Close or End a Business If you leave the account open, the state keeps expecting quarterly NYS-45 filings, and each missed filing triggers the $1,000-plus penalty even though you have no wages to report.
