What Is the IT-2104 Form?

The IT-2104, officially known as the Employee’s Withholding Allowance Certificate, is a New York State-specific form that instructs your employer on the amount of New York State income tax (and, if applicable, New York City or Yonkers taxes) to withhold from your wages. It’s the state equivalent of the federal W-4 form, allowing you to claim allowances based on your personal and financial situation. These allowances reduce the taxable portion of your income for withholding purposes—more allowances mean less tax withheld per paycheck, and vice versa.

This form is administered by the New York State Department of Taxation and Finance and must be submitted to your employer, not directly to the tax department (unless specific conditions apply, like claiming over 14 allowances). It’s designed to help match your withholdings to your expected tax liability, minimizing underpayments or overpayments that could lead to penalties or large refunds.

For 2026, the form is available as a fillable PDF, making it easier to complete digitally. Employers use the details you provide—such as your filing status, number of dependents, and additional income—to calculate withholdings accurately.

Who Needs to File the IT-2104 Form in 2026?

Not every employee needs to submit a new IT-2104 each year, but certain triggers make it necessary. According to official guidelines, you should complete and submit the form if:

  • You’ve experienced life events like marriage, divorce, having a child, or moving in/out of New York City or Yonkers.
  • Your income has changed significantly, such as earning over $107,650 individually or combined with a spouse, or starting/stopping a second job.
  • You’re itemizing deductions, claiming New York State tax credits (e.g., earned income credit or child care credit), or your tax situation has shifted (e.g., owing taxes or getting a large refund last year).
  • You’re a new hire or your employer participates in programs like the Employer Compensation Expense Program.

If you submitted a federal W-4 for 2020 or later without an accompanying IT-2104, your employer might default to zero allowances, which could result in over-withholding. Always review your form annually, especially around January, to reflect any changes.

Exemptions from withholding require a separate form, like the IT-2104-E for 2026, if you expect no tax liability and meet specific criteria.

Key Changes to the IT-2104 Form for 2026

The 2026 version of the IT-2104 has been updated to reflect current tax laws, and if you filed a previous version before January 1, 2026, you’ll need to submit a new one using the revised worksheets and charts. These revisions ensure better alignment with federal changes post-2019, where the W-4 no longer uses allowances in the same way.

Notable updates include refined worksheets for calculating allowances, especially for multiple jobs, married couples, and high earners (wages over $107,650). The form now emphasizes using Parts 5 and 6 charts for additional withholding amounts in scenarios like combined spousal incomes or multiple employments. Thresholds for dependent income ($3,100) and itemized deductions remain consistent, but always verify with the latest instructions to avoid under-withholding penalties.

The New York State Tax Department has also made the 2026 forms available early, with fillable options for IT-2104 and IT-2104-E.

Step-by-Step Guide: How to Fill Out the IT-2104 Form 2026

Filling out the IT-2104 is straightforward but requires attention to detail. Use the accompanying worksheets in the instructions to calculate accurately. Here’s a breakdown:

  1. Personal Information: Enter your name, Social Security number, filing status (Single, Married, or Head of Household), and address. Mark if you’re a New York City or Yonkers resident.
  2. Claim Allowances (Line 1 – New York State/Yonkers): Use Part 1 worksheet. Start with dependents (exclude yourself/spouse), add credits (e.g., 3 for Empire State child credit), and adjust for heads of household (+2 if one job). Subtract for non-wage income over $1,000 or federal adjustments. Transfer the total to Line 1.
  3. New York City Allowances (Line 2): If a NYC resident, use Part 4. Similar to Line 1 but without certain credits.
  4. Additional Withholding (Lines 3-5): If you need extra tax withheld (e.g., due to multiple jobs or negative allowances), enter amounts here. Use Parts 5/6 charts for married couples or multi-job holders with combined wages over $107,650.
  5. Special Cases:
    • Multiple Jobs: Claim all allowances on your highest-paying job; zero on others.
    • Itemized Deductions: Complete Part 2 to add extra allowances if your deductions exceed the standard (e.g., $8,000 for single non-dependents).
    • Over 14 Allowances: Your employer must submit a copy to the Tax Department.
    • Negative Allowances: Enter 0 and request additional dollar amounts (e.g., $1.85/week for NYS per negative allowance).
  6. Sign and Date: Submit to your employer. Keep a copy for your records.

For precise calculations, refer to the divisor tables for credits and pay frequency adjustments in the instructions.

Common Mistakes to Avoid When Completing IT-2104 2026

  • Not Updating Annually: Life changes can alter your allowances—don’t set it and forget it.
  • Confusing Federal and State Forms: The IT-2104 is separate from the W-4; mismatches can lead to incorrect withholdings.
  • Overclaiming Allowances: This might result in owing taxes plus penalties. Use worksheets to stay accurate.
  • Ignoring Additional Income: Forget to reduce allowances for side gigs or investments? You could under-withhold.
  • Employer Errors: If claiming over 14, ensure your employer reports it properly to avoid audits.

By double-checking with the official worksheets, you can sidestep these issues.
