When you manage a small business, payroll tax rules can feel overwhelming. But knowing when and how to pay these taxes helps you avoid costly fines. Understanding the timing of federal, state, and local tax payments keeps your business on the right track. In this guide, we will break down common payroll taxes and their schedules. We will also discuss common errors and penalties, plus offer tips on how to stay compliant.
Federal Payroll Taxes (Form 941)
Employers must deposit federal payroll taxes (including Social Security, Medicare, and withheld income tax) based on their “lookback period.” This lookback period reviews the total taxes paid in a past timeframe—usually four quarters ending on June 30 of the previous year. The amount you paid then sets your new deposit schedule.
Semi-Weekly or Monthly 941 Tax Deposits:
- Monthly Depositors: If you reported less than $50,000 in total taxes during the lookback period, you deposit monthly. Your deposits are due by the 15th of the following month. For example, taxes withheld in January are due by February 15.
- Semi-Weekly Depositors: If you reported $50,000 or more in total taxes during the lookback period, you must follow a semi-weekly deposit schedule. Taxes from paydays on Wednesday, Thursday, or Friday are due by the next Wednesday. Taxes from paydays on Saturday, Sunday, Monday, or Tuesday are due by the next Friday.
For more details on these rules, check the IRS Instructions for Form 941.
State Unemployment Insurance (SUI)
State unemployment tax deadlines vary by state, but most states require quarterly filings. Generally, the payment is due on the last day of the month following the end of the quarter. For instance, the first quarter ends March 31, and your payment is due by April 30.
Because rules differ across states, confirm your exact due dates with your state’s labor department or your payroll provider. Timely filing ensures your business stays in good standing with local laws.
State Withholding Taxes
State withholding taxes often follow a more flexible schedule. The timing can vary based on how much you withhold in a given period. Larger amounts often mean more frequent deposits—sometimes semi-weekly or monthly. Smaller amounts may only require quarterly or annual filings. Verify your specific state rules by checking with your state’s tax website or speaking with a payroll expert.
Local and Municipal Payroll Taxes
Some cities or counties require their own withholding taxes. These local taxes must be deposited according to their own schedules. Many require quarterly or monthly deposits. Be sure to review your local tax authority’s guidelines. For detailed instructions, you can contact the local tax office or consult a trusted payroll provider like Valor Payroll Solutions.
Common Errors and Penalties
Errors in tax timing can lead to serious penalties. Missing a deadline or underpaying may trigger interest charges, penalty fees, or even an audit. Common mistakes include:
- Misreading the Lookback Period:
Failing to review your past filing history can cause you to choose the wrong deposit schedule. This leads to late deposits and penalties. - Forgetting Quarterly Deadlines:
Ignoring state unemployment due dates or state withholding schedules can result in fines. Marking your calendar and automating reminders helps you avoid late payments. - Not Tracking Local Taxes:
Overlooking local payroll tax requirements can cause problems. Always review city or county rules if they apply to you.
Penalties Add Up Fast:
Late deposits can incur fees that range from a small percentage of unpaid taxes to much larger amounts, depending on the length of the delay. The IRS and state agencies apply these penalties to encourage timely compliance. To lower your risk, stay organized, use payroll software, or partner with a reliable payroll service provider.
How to Stay Compliant
- Track Your Deadlines: Mark all key dates on your calendar. Set digital reminders for upcoming due dates.
- Use a Payroll Service: A professional payroll provider can manage these tasks for you. For example, Valor Payroll Solutions’ Payroll Services offer guidance and support, ensuring you meet each due date.
- Check State and Local Guidelines: Each area has its own rules. Read your state’s official site or call their helpline. Check city or county websites for local tax information.
- Automate When Possible: Many online payroll platforms allow you to set up automatic payments. These systems help reduce human error and keep you on track.

Understanding payroll tax deadlines and frequencies is essential for your small business. Knowing the federal lookback periods, state unemployment schedules, state withholding rules, and local tax due dates helps you avoid penalties. Prevent errors by staying organized, using the right tools, and considering expert help.
By learning these schedules and following the rules, you save time, avoid penalties, and focus on what matters: growing your business.
