1. Register the actual employing business
New York directs a business hiring employees to obtain its federal EIN and register for unemployment insurance, withholding and wage reporting. Tax-account registration is separate from the entity’s authority to do business and insurance coverage.
- Identify the employing entity, New York worksites and first expected wage payment.
- Use New York Business Express or the applicable NYS-100 process.
- Save account confirmations and establish the correct Tax Online Services access for any authorized filer.
| Form / process | Purpose | Who acts |
|---|---|---|
| NYS-100 New York State Employer Registration for Unemployment Insurance, Withholding, and Wage Reporting | Employer registration; the applicable process depends on employer type. | Actual employing business or authorized representative |
2. Obtain the correct withholding instructions
An employee’s New York withholding certificate is distinct from their federal W-4. Residence and work details also matter for New York City and Yonkers withholding questions. Use the current certificate and instructions rather than assuming one state rate applies to every worker.
- Collect the employee’s state certificate through a secure employer process.
- Check residence, work location and any city-specific certificate requirements.
- Update withholding when circumstances or employee instructions change.
| Form / process | Purpose | Who acts |
|---|---|---|
| IT-2104 Employee’s Withholding Allowance Certificate | Employee instructions for New York State, New York City and Yonkers withholding as applicable. | Employee completes; employer applies and retains |

3. Separate quarterly reporting from tax payments
NYS-45 brings together withholding reconciliation, wage reporting and unemployment insurance reporting. NYS-1 handles withholding payments on the applicable schedule. A quarterly report does not mean all withholding may wait until quarter end; payment deadlines can arise during the quarter.
- Determine the employer’s current withholding payment schedule.
- Reconcile NYS-45 totals to payroll, payments and employee wage detail.
- Check due-date adjustments, nil-reporting obligations and final-return steps.
| Form / process | Purpose | Who acts |
|---|---|---|
| NYS-45 Quarterly Combined Withholding, Wage Reporting, and Unemployment Insurance Return | Combined quarterly employer reporting. | Employer or authorized filer |
| NYS-1 Return of Tax Withheld | Remittance of withheld tax when the applicable payment rules require it. | Employer or authorized payer |
4. Complete hiring and insurance checks
New-hire reporting and employment insurance are separate from quarterly tax reporting. New York’s employer guidance describes a 20-day new-hire reporting requirement. Workers’ compensation, disability benefits and paid family leave each need an applicability and coverage check.
- Set the new-hire reporting process and responsible person.
- Confirm required coverage with the carrier for the business and assignments.
- Keep policy evidence, statutory notices and filing records with the employer.
5. Review construction classification and registration
The Construction Industry Fair Play Act presumes covered construction workers are employees unless its criteria are met. Its independent-contractor and separate-business tests require substantive facts; a contract label or Form 1099 is insufficient. Public work and certain covered private projects also have contractor-registration requirements.
- Document the working relationship against the applicable state and federal tests.
- Check whether the contractor and subcontractors need the NYSDOL registry.
- Review the specific project’s wage, benefit, recordkeeping and payroll-reporting requirements.
Before applying this guide
- This is research for a worked website example, not a filing instruction or confirmation that a business or worker is eligible.
- Requirements depend on the actual employer, worksite, worker residence, industry, contract and employment arrangement. Check the linked agency guidance before relying on a form or deadline.
- Online services, form editions and filing rules can change. Checked dates record research, not a guarantee that every rule remains current.
- Construction classification tests do not replace federal tax, immigration or other applicable legal tests.
- New York City, Yonkers, public-work and covered private-project questions require project-specific review.
