Where Federal Payroll Taxes Go and How to Send Them

Federal payroll taxes are sent to the Internal Revenue Service (IRS) through a system called the Electronic Federal Tax Payment System, or EFTPS. If you are an employer, you withhold taxes from employee paychecks and send them to the IRS on a schedule set by the IRS based on how much you owe. If you are self-employed, you send estimated taxes four times a year. The IRS does not accept checks mailed to a local office — all payments go through EFTPS, a credit card processor, or your bank's bill-pay system.

The amount you owe and when you owe it depends on your business structure and the size of your payroll. A sole proprietor with one employee pays on a different schedule than a corporation with fifty employees. The IRS publishes a deposit schedule each year that tells you whether you deposit weekly, biweekly, monthly, or quarterly. Missing a deposit deadline triggers penalties and interest, even if you pay the full amount later.

Key Takeaways

  • Employers must enroll in EFTPS or use a third-party payroll processor to send federal payroll taxes to the IRS; mailing checks is not an option.
  • Your deposit schedule — weekly, biweekly, monthly, or quarterly — is determined by the IRS based on your total payroll and is published each year.
  • Self-employed people pay estimated taxes four times per year (April 15, June 15, September 15, and January 15) using Form 1040-ES.
  • Penalties for late deposits start at 2 percent of the unpaid amount and increase if the payment is more than 15 days late.
  • Payroll processors, accountants, and banks can handle deposits on your behalf, but you remain responsible if a payment is missed or miscalculated.

Setting Up EFTPS or Using a Payroll Processor

To pay through EFTPS directly, you must enroll on the IRS website at eftps.gov. Enrollment takes about five minutes and requires your Employer Identification Number (EIN), Social Security Number, and bank account information. The IRS will mail you a Personal Identification Number (PIN) within two weeks. Once you have the PIN, you can log in and schedule payments online or by phone.

Many employers skip EFTPS and use a payroll processor instead — companies like ADP, Gusto, Paychex, or Square Payroll. These services calculate withholdings, print paychecks, and send deposits to the IRS automatically. You pay a monthly fee (typically $20 to $300 depending on the number of employees), but the processor handles the timing and math. If the processor makes an error, you are still liable to the IRS, so verify that deposits were received by checking your IRS account online at irs.gov/payments.

Some banks offer bill-pay services that let you schedule tax payments directly from your business account. This works if you know the exact amount owed and the due date, but it does not calculate withholdings or track your deposit schedule. Use this method only if you are comfortable managing the math yourself.

Deposit Schedules: When Payments Are Due

The IRS assigns you to one of two deposit schedules: semi-weekly or monthly. Which one you use depends on the total federal income tax and Social Security and Medicare taxes you reported in the prior year. If you reported $50,000 or less in the prior four quarters, you are on the monthly schedule. If you reported more than $50,000, you are on the semi-weekly schedule.

On the monthly schedule, deposits are due on the 15th of the following month. If you pay employees on the last day of January, your deposit for those wages is due February 15. On the semi-weekly schedule, the due date depends on the day you pay employees. Wages paid Wednesday through Friday are due the following Wednesday. Wages paid Saturday through Tuesday are due the following Friday. This means you may owe deposits twice per week.

The IRS publishes a deposit schedule calendar each October for the coming year. Download it from irs.gov or ask your payroll processor to provide it. If a due date falls on a weekend or federal holiday, the deposit is due the next business day. Deposits made after midnight on the due date are considered late, even if submitted before business hours the next morning.

Self-Employment Tax Payments and Estimated Taxes

If you are self-employed — a sole proprietor, partner, or S-corporation owner — you do not have an employer to withhold taxes for you. Instead, you pay estimated taxes four times per year using Form 1040-ES. These payments cover federal income tax, Social Security tax, and Medicare tax on your net business income.

Estimated tax payments are due on April 15, June 15, September 15, and January 15 of the following year. You calculate what you owe by estimating your annual net income and using the worksheet in Form 1040-ES. If your income varies, you can adjust the amount each quarter. Pay through EFTPS, by credit card at irs.gov/payments, or by mailing a check with Form 1040-ES to the address listed on the form.

If you underpay estimated taxes, the IRS charges interest and a penalty when you file your annual return. If you overpay, the excess is credited to your next year's taxes or refunded. Many self-employed people work with an accountant to calculate estimated taxes, especially if income is irregular or they have multiple income sources.

What Happens If You Miss a Deposit

Late payroll tax deposits trigger a failure-to-deposit penalty starting at 2 percent of the unpaid amount. If the payment is 1 to 5 days late, the penalty is 2 percent. If it is 6 to 15 days late, the penalty is 5 percent. If it is more than 15 days late, the penalty is 10 percent. The IRS also charges interest on the unpaid balance from the due date forward, compounded daily.

If you discover you missed a deposit, contact the IRS immediately. Call the Business and Specialty Tax Line at 1-800-829-4933. The IRS may reduce or waive the penalty if you have a reasonable cause — for example, a payroll processor error or a bank system failure — and you correct the mistake quickly. Do not wait until tax season to report the error.

Repeated or large missed deposits can trigger an IRS audit, a demand for immediate payment, or a federal tax lien on your business assets. If you cannot pay the full amount owed, you can request a payment plan through the IRS, but interest and penalties continue to accrue until the balance is paid in full.

Reconciling Payroll Taxes on Your Annual Return

At the end of the year, you file Form 941 (Employer's Quarterly Federal Tax Return) or Form 944 (Employer's Annual Federal Tax Return) to reconcile what you withheld and paid against what you actually owed. Most employers file Form 941 quarterly; smaller employers with less than $1,000 in annual payroll tax may file Form 944 once per year.

Form 941 lists total wages paid, total federal income tax withheld, total Social Security and Medicare taxes withheld, and the deposits you made during the quarter. If your deposits were more than what you owed, the IRS credits the overpayment to the next quarter or refunds it. If your deposits were less than what you owed, you owe the difference when you file the form.

Self-employed people reconcile on Schedule SE (Self-Employment Tax) and Schedule C (Profit or Loss from Business), both filed with Form 1040. If you overpaid estimated taxes, the excess is credited or refunded when you file. If you underpaid, you owe the difference plus interest and penalties.

Common Mistakes and How to Avoid Them

The most common payroll tax mistake is calculating the wrong withholding amount. Employees complete Form W-4 when hired, telling you how many allowances to claim. If an employee claims too many allowances, you withhold too little, and the employee owes taxes at year-end. If they claim too few, you withhold too much, and they receive a refund. Review W-4s when employees are hired and whenever they request a change.

Another frequent error is confusing the deposit due date with the paycheck date. Your deposit is due based on when you pay employees, not when you process payroll. If you pay employees on Friday but do not deposit until Monday, the deposit may be late depending on your schedule. Use a calendar to track both dates.

A third mistake is using the wrong payroll tax rate. Social Security tax is 6.2 percent on wages up to a cap (the cap changes each year), and Medicare tax is 1.45 percent on all wages. Self-employed people pay both the employer and employee portions, totaling 15.3 percent on net self-employment income. Payroll processors calculate this automatically, but if you calculate manually, verify the rates each January on irs.gov.

Frequently Asked Questions

Can I pay payroll taxes by check or money order?

No. The IRS only accepts payroll tax payments through EFTPS, credit card processors, or bank bill-pay systems. Checks mailed to an IRS office will be returned. If you must pay by check, contact the IRS to request a waiver, which is rarely granted.

What if my payroll processor sends the payment late without my knowledge?

You are responsible for the deposit, even if the processor made the error. Review your IRS account online at irs.gov/payments each month to confirm deposits were received on time. If a deposit is late, contact the processor immediately and request they file a penalty abatement request with the IRS on your behalf.

Do I have to pay payroll taxes if my business has no profit?

Yes. Payroll taxes are withheld from employee wages regardless of whether your business is profitable. Self-employed people pay estimated taxes based on net income; if you have a loss, you may owe nothing, but you should still file Form 1040-ES to avoid penalties.

What is the difference between payroll taxes and income tax withholding?

Payroll taxes include Social Security and Medicare taxes (6.2 percent and 1.45 percent). Income tax withholding is a separate amount based on the employee's Form W-4. Both are withheld from paychecks and sent to the IRS on the same deposit schedule.

Can I use a credit card to pay payroll taxes?

Yes, but only through approved payment processors on irs.gov/payments. Credit card companies charge a processing fee (typically 1.87 to 2.35 percent of the payment), so the total cost is higher than paying by bank transfer through EFTPS.
