Employers in New York State must stay on top of payroll reporting, and Form NYS-45 is one of the most important filings to get right.
This quarterly return combines withholding tax, unemployment insurance, and employee wage reporting into one required submission.
What New York Form NYS-45 Is and Why It Matters
Form NYS-45, the Quarterly Combined Withholding, Wage Reporting, and Unemployment Insurance Return, is required for most employers with New York payroll obligations.
It gives the state a full picture of wages paid, taxes withheld, and unemployment insurance contributions due each quarter.
Because it serves multiple reporting purposes at once, the form is a core compliance document for New York employers.
New York Form NYS-45 Filing Deadlines
Form NYS-45 is due by the last day of the month following the end of each calendar quarter.
That means the filing schedule is set up around four standard deadlines each year.
- First Quarter: April 30
- Second Quarter: July 31
- Third Quarter: October 31
- Fourth Quarter: January 31
If a deadline falls on a Saturday, Sunday, or legal holiday, the due date moves to the next business day.
Missing a deadline can create avoidable penalties, so payroll teams should build quarterly reminders into their process.

New York Form NYS-45 Electronic Filing Rules
As of March 2025, all employers are required to file Form NYS-45 electronically.
The New York State Department of Taxation and Finance offers a free Web File system that supports direct payment from a bank account, instant confirmation, and automatic calculation of amounts due.
This shift to mandatory e-filing makes the process more efficient, but it also means employers need digital access and accurate payroll records before filing day.
Why Electronic Filing Helps
Electronic filing reduces paper handling and lowers the chance of mailing errors or lost forms.
It also gives employers immediate proof that the return was submitted successfully.
New York Form NYS-45 Parts A, B, and C
Form NYS-45 is organized into three parts, and each section serves a different reporting purpose.
Understanding what belongs in each part helps employers avoid filing delays and incomplete returns.
Part A: Unemployment Insurance Information
Part A covers unemployment insurance details, including the employer registration number and UI contributions.
This part is essential for reporting the employer’s unemployment tax liability for the quarter.
Part B: Withholding Tax Information
Part B reports the total amount of New York State, New York City, and Yonkers income tax withheld from employees.
Employers must make sure the amounts in this section match payroll records and any deposits already made during the quarter.
Part C: Wage Reporting Information
Part C requires quarterly employee and payee wage reporting, including detailed wage and withholding information for each worker.
This section is where employers provide the state with the employee-level data needed for accurate benefit and tax administration.

New York Form NYS-45 Wages You Must Report
Employers must report all forms of compensation paid to covered employees, not just regular hourly wages.
That includes a broad range of earnings and other compensation types tied to work performed.
- Salary
- Tips
- Cash wages
- Vacation pay
- Commissions
- Bonuses
- Other non-cash compensation
Payroll records should capture these items consistently, especially in industries where tips and commissions are common.
Accurate wage reporting matters because the information may affect withholding, unemployment insurance, and employee recordkeeping.
New York Form NYS-45 and the Unemployment Insurance Wage Base
Beginning in 2026, New York’s unemployment insurance wage base will adjust annually to 18% of the state average annual wage, rounded up to the nearest $100.
For 2026, that amount is set at $17,600.
This annual adjustment means employers should review payroll systems each year to make sure UI calculations reflect the current wage base.
Even small payroll errors can affect total contributions, so staying current with the wage base is important for compliance.
New York Form NYS-45 Amended Returns
If an employer discovers an error after filing, the state requires a complete new filing rather than just sending corrected lines.
That means all return parts and all employee records must be included again, not only the changes.
This full re-filing approach helps the state process the correction accurately and reduces the risk of delays or penalties.
Employers should keep copies of original submissions and payroll reports so amendments can be prepared quickly if needed.
New York Form NYS-45 Seasonal Employer Status
Certain employers with a seasonal business model may qualify for seasonal employer status if they do not pay wages subject to income tax withholding and unemployment insurance contributions in at least one quarter of the calendar year.
To request this status, the employer must file Form NYS-45 and mark the seasonal employer box.
Once approved, the employer is not required to file Form NYS-45 for later quarters in the same calendar year during which no such wages were paid.
This can be especially helpful for businesses that operate only during part of the year.
New York Form NYS-45 Compliance Tips for Employers
Good compliance starts with organized payroll records and a clear filing calendar.
Employers should reconcile wages, withholding, and UI contributions before every quarterly submission.
Keep Payroll Records Clean
Review employee wage data throughout the quarter instead of waiting until the deadline.
That makes it easier to catch missing tips, bonus payments, or classification issues before they affect the return.
Match Deposits To Returns
The amounts reported on Form NYS-45 should align with payroll tax deposits made during the quarter.
Any mismatch can trigger questions or slow down processing.
Review Employee Details
Employee names, identification details, and wage entries should be checked carefully before filing.
Small data entry mistakes can create problems in wage reporting and later corrections.
