3. Receiving income through LLCs, partnerships, or S corporations

6. Step-by-Step: New York State Tax Filing

Step 1: Confirm your New York filing requirement

Determine whether you are a New York resident, part-year resident, or nonresident. Filing is generally required if you meet income thresholds or earn New York-source income, even if no tax is ultimately owed.

Step 2: Obtain or confirm your EIN (if applicable)

Businesses, LLCs, partnerships, and corporations must have a valid Employer Identification Number (EIN) issued by the Internal Revenue Service (IRS) . An EIN is required for filing New York business tax returns, payroll tax forms, and employer withholding reports.

Step 3: Prepare your federal tax return first

New York state tax filing is based largely on information reported on your federal income tax return filed with the IRS. Individuals generally begin with IRS Form 1040, while businesses use the applicable federal business return.

Step 4: Gather New York-specific income and withholding records

Collect W-2s, 1099s, Schedule K-1s, and any New York state withholding documents. Nonresidents and part-year residents should identify income sourced specifically to New York.

Step 5: Select and complete the correct New York tax form

Full-year residents generally file Form IT-201, while part-year residents and nonresidents file Form IT-203. Businesses file the appropriate New York returns based on entity type and activity.

Step 6: File and pay by the deadline

Most individual New York income tax returns are due by April 15 (or the next business day if it falls on a weekend or holiday). Filing extensions extend the deadline to file, but not the deadline to pay any tax due.

Step 7: Retain records and plan ahead

Keep copies of your filed federal and New York tax returns, payment confirmations, and EIN documentation for future reference. Maintaining organized records helps simplify compliance and future New York tax filings.

7. Tips to Avoid New York Tax Notices
