IRS Form W‑4S – Fillable PDF for Sick Pay Tax Withholding

Form W‑4S, officially titled Request for Federal Income Tax Withholding From Sick Pay, is the IRS document you give to a third‑party payer (such as an insurance company) so that federal income tax can be withheld from your sick‑pay benefits.

What Is Form W‑4S?

This one‑page form has two parts: a Withholding Certificate that the payer keeps, and a Worksheet for your records. The certificate tells the payer how much tax you want taken out of each payment, while the worksheet helps you calculate the correct amount based on your projected income, deductions, and credits.

  2. Wait a few seconds while the Formize PDF Filler app loads the official IRS PDF.
  3. Enter your personal information, Social Security number, and the exact dollar amount you want withheld.
  4. Complete the worksheet section to verify your calculation.
  5. Review the completed form, then click **Submit** to download a signed copy or print it for your payer.

When Should You Use Form W‑4S?

Use this form whenever you receive sick‑pay from a third‑party payer (e.g., an insurance carrier) and you want federal tax withheld. It is not required when the sick pay comes directly from your employer, because employers already withhold taxes.

Common Mistakes to Avoid

  • Entering amounts in cents – the IRS requires whole‑dollar amounts only.
  • Withholding less than the minimum: $4 per day, $20 per week, or $88 per month.
  • Reducing your net payment below $10 – the payer cannot withhold more than the payment allows.
  • Forgetting to sign and date the form – an unsigned form is invalid.

Where to Find Help

If you have questions about the calculations, consult the IRS instructions (linked on the form) or a tax professional. You can also review our detailed FAQ below.

FAQ
  • Do I need to file Form W‑4S with the IRS?

    No. You give the completed certificate to the third‑party payer of your sick pay. Keep the worksheet for your records.

  • Can I change the withholding amount later?

    Yes. Submit a new Form W‑4S whenever your financial situation changes or you want a different withholding amount.

  • What is the minimum amount the IRS allows me to withhold?

    The minimum is $4 per day, $20 per week, or $88 per month. The payer cannot withhold less than these amounts.

  • Is the Formize filler truly free?

    Yes. Formize provides a free, secure online PDF filler for IRS forms, including Form W‑4S.

  • What if my sick‑pay provider is my employer?

    Employers already withhold federal tax from sick pay, so Form W‑4S is not required in that case.

  • Can I submit the form electronically to the payer?

    Most third‑party payers accept a printed copy. Check with your payer; some may allow a scanned PDF upload.

  • What happens if I withhold too much?

    Any excess tax withheld will be refunded to you when you file your annual tax return.

  • Do I need to attach the worksheet to the payer?

    No. The worksheet is for your personal records only; only the top part of the form goes to the payer.

Tax forms

Form W-4S is one of Tax forms that are documents used to report income, deductions, and tax liability to the relevant tax authority. These forms are an essential part of the tax filing process and are used to ensure individuals and businesses comply with tax laws and accurately calculate their tax obligations.

The specific tax forms required can vary depending on factors such as an individual's filing status, sources of income, and the country's tax laws. However, here are some common types of tax forms:

Individual Income Tax Forms: These forms, such as the 1040 series in the United States, are used by individuals to report their income, claim deductions and credits, and calculate their tax liability.

Business Tax Forms: Businesses, including sole proprietorships, partnerships, corporations, and self-employed individuals, may have to file various forms to report their income, expenses, and taxes owed. Examples include Schedule C (Profit or Loss from Business) and Form 1120 (U.S. Corporation Income Tax Return).

Employment Tax Forms: Employers are required to report employee wages and withhold and remit payroll taxes. Forms such as W-2 (Wage and Tax Statement) and 941 (Employer's Quarterly Federal Tax Return) are used for this purpose.

Investment and Retirement Account Forms: These forms are used to report investment income, capital gains, and losses, as well as contributions and distributions from retirement accounts. Examples include Form 1099-DIV (Dividends and Distributions) and Form 5498 (IRA Contribution Information).

Estate and Gift Tax Forms: When a person passes away or makes significant gifts, specific forms such as Form 706 (United States Estate (and Generation-Skipping Transfer) Tax Return) and Form 709 (United States Gift (and Generation-Skipping Transfer) Tax Return) are used to report and calculate any applicable estate or gift taxes.

It is important to note that tax laws and forms can change over time, so individuals and businesses should consult the relevant tax authority or seek professional tax advice to ensure compliance with the current requirements.
