Payroll taxes are not deductible for employees, but business owners can deduct the employer portion they pay

If you are an employee, you cannot deduct the payroll taxes withheld from your paycheck. The Social Security and Medicare taxes taken out of your wages are straightforward gone — they do not reduce your taxable income on your tax return. The IRS treats these as personal taxes, not business expenses, even though your employer withheld them.

If you are self-employed or a business owner, the situation is different. You can deduct the employer portion of self-employment tax (the half you pay on your own behalf) as an adjustment to income on Form 1040. This deduction appears on line 27 of the 2024 Form 1040 and reduces your adjusted gross income before you calculate other deductions.

The employee portion of self-employment tax — the half that mirrors what a W-2 employee pays — cannot be deducted. Only the employer half qualifies.

Key Takeaways

  • W-2 employees cannot deduct any payroll taxes withheld from their paychecks on their personal tax return.
  • Self-employed people and business owners can deduct the employer portion of self-employment tax as an adjustment to income on Form 1040, line 27.
  • The employee portion of self-employment tax (approximately 50 percent of what you owe) is not deductible.
  • This deduction reduces your adjusted gross income and may lower your taxable income for the year.

Why employees cannot deduct payroll taxes

The IRS classifies payroll taxes withheld from your paycheck as personal taxes, not business or investment expenses. Your employer is required to withhold these taxes and send them to the government on your behalf, but the money comes from your wages. Because it is your personal income being taxed, you have no deduction available.

This is different from income tax withholding. You also cannot deduct federal income tax withheld from your paycheck. The withholding is straightforward a payment toward your final tax bill — it is not an expense you incurred in earning the income.

Some people confuse this with the standard deduction or tax credits, which do reduce taxable income. Payroll tax withholding is neither. It is a prepayment of tax you owe, and prepayments are not deductible.

How self-employed people deduct the employer portion

If you are self-employed, you pay both the employee and employer portions of Social Security and Medicare tax. The combined rate is 15.3 percent of your net self-employment income (12.4 percent for Social Security on income up to a cap, and 2.9 percent for Medicare with no cap).

You calculate self-employment tax on Schedule SE (Form 1040). Once you know the total, you can deduct half of it — the employer half — on Form 1040, line 27. This deduction is taken before you calculate your adjusted gross income, which means it reduces the income that other deductions and credits are based on.

For example, if your self-employment tax totals $4,000, you deduct $2,000 on line 27. The other $2,000 (the employee portion) stays with you and is not deductible.

The difference between the employee and employer portions

Self-employment tax is split into two equal halves by law. The first half (7.65 percent) represents what an employee would pay. The second half (7.65 percent) represents what an employer would pay. Only the employer half is deductible.

This split exists because self-employed people are both the employee and the employer. The IRS allows you to deduct the employer half because, in theory, an employer's payroll taxes are a business expense. But the employee half mirrors the personal tax withheld from a W-2 employee's paycheck, and personal taxes are not deductible.

You will see this split clearly on Schedule SE. The form calculates your total self-employment tax, then shows the deductible portion separately. You transfer the deductible amount to Form 1040, line 27.

What happens if you miss this deduction

If you are self-employed and do not claim the self-employment tax deduction on line 27, you will pay more tax than you owe. The deduction is not automatic — you must calculate it on Schedule SE and transfer it to the correct line on Form 1040.

If you file your return without this deduction, you can file an amended return (Form 1040-X) to claim it. The IRS will not automatically correct this for you. Many self-employed people miss this deduction because they do not realize it exists or because they use tax software that does not prompt them to enter it.

The deduction is worth roughly 7.65 percent of your net self-employment income. For someone with $50,000 in net self-employment income, that is about $3,825 in deductible self-employment tax, which could save $900 to $1,200 in federal income tax depending on your tax bracket.

Payroll taxes paid by your business as an employer

If you have employees and pay payroll taxes on their behalf, those taxes are a business expense and are fully deductible on your business tax return (Form 1120, 1120-S, 1065, or Schedule C, depending on your business structure). This is different from the self-employment tax deduction and is handled separately.

Employer payroll taxes are deducted as a business expense, not as an adjustment to income. They reduce your business income before you calculate profit or loss. This deduction is taken on the business return itself, not on your personal Form 1040.

Keep records of all payroll taxes paid throughout the year. Your payroll processor or accountant should provide a summary, and the IRS will also send you Form 941 (quarterly) or Form 944 (annual) showing what you reported and paid.

State and local payroll taxes

Some states and cities impose their own payroll taxes on employees or employers. The deductibility of these taxes follows the same rules as federal payroll taxes: employees cannot deduct them, but self-employed people may be able to deduct the employer portion if their state allows it.

A few states do not have income tax but do have payroll taxes for specific programs (such as disability insurance or family leave). Check your state's tax agency website to learn whether these are deductible on your federal return. Some state payroll taxes are deductible federally, and some are not.

If you pay state or local income tax, that is a separate deduction available to all taxpayers through the state and local tax (SALT) deduction, which is capped at $10,000 per year. Payroll taxes are not part of the SALT deduction.

Frequently Asked Questions

Can I deduct payroll taxes if I am a W-2 employee?

No. Payroll taxes withheld from your paycheck are not deductible on your personal tax return. They are treated as personal taxes, not business expenses. You cannot reduce your taxable income by the amount of Social Security or Medicare tax taken out of your wages.

Do I have to claim the self-employment tax deduction or is it automatic?

You must claim it yourself. Calculate your self-employment tax on Schedule SE, then transfer the deductible portion (the employer half) to Form 1040, line 27. Tax software will usually prompt you for this, but if you file by hand or use incomplete software, you must remember to include it.

What if I am both an employee and self-employed?

You cannot deduct the payroll taxes withheld from your W-2 job. You can deduct the employer portion of self-employment tax from your self-employment income on Schedule SE and Form 1040, line 27. These are separate calculations and both explore to your return.

Are employer payroll taxes deductible as a business expense?

Yes. If you have employees, the payroll taxes you pay on their behalf are fully deductible as a business expense on your business tax return. This is different from the self-employment tax deduction and is handled on your business return, not your personal Form 1040.

Can I deduct payroll taxes I paid in a previous year?

Only if you did not claim them in that year. If you missed the self-employment tax deduction in a prior year, you can file an amended return (Form 1040-X) for that year to claim it. You generally have three years from the original due date to amend and claim the deduction.
