Semiweekly Tax Deposit Schedule

For businesses in the United States, staying compliant with federal tax laws includes making timely employment tax deposits. One common requirement for employers is adhering to a semiweekly tax deposit schedule. This schedule applies based on the amount of payroll taxes owed and how frequently employees are paid. Understanding how the semiweekly deposit schedule works, who must follow it, and when deposits are due is crucial for avoiding penalties and ensuring smooth operations within a company’s payroll system.

Understanding the Semiweekly Tax Deposit Schedule

The semiweekly deposit schedule is part of the IRS rules that dictate how often employers must deposit employment taxes. These taxes typically include withheld federal income tax, Social Security tax, and Medicare tax. Whether an employer follows a monthly or semiweekly schedule depends on their reported tax liability during a specific lookback period.

What Is the Lookback Period?

The IRS determines an employer’s deposit schedule using a four-quarter lookback period. For example, for the 2025 calendar year, the lookback period would be from July 1, 2023, through June 30, 2024. During this time, the IRS reviews the employer’s total tax liability reported on Form 941, Employer’s Quarterly Federal Tax Return.

• If the total tax liability during the lookback period is $50,000 or less, the employer is a monthly depositor.
• If the liability exceeds $50,000, the employer is a semiweekly depositor.

It is important to note that once assigned to a semiweekly schedule, employers must follow those deposit rules regardless of how often they pay their employees.

Semiweekly Deposit Schedule: Key Rules and Dates

The semiweekly deposit schedule is based on the day wages are paid to employees, not the day they are earned. The IRS sets specific deposit due dates for paydays that fall on different days of the week:

• Paydays on Wednesday, Thursday, or Friday: Deposit taxes by the following Wednesday.
• Paydays on Saturday, Sunday, Monday, or Tuesday: Deposit taxes by the following Friday.

Here’s a practical example. If a business pays employees on Friday, July 18, 2025, the deposit must be made by Wednesday, July 23, 2025. If payday falls on Monday, July 21, 2025, the deposit is due by Friday, July 25, 2025.

Exceptions and Holidays

When a deposit due date falls on a federal holiday, the deposit is due on the next business day. Employers should regularly review the IRS holiday calendar to avoid accidental late deposits, which may result in penalties.

How to Make Semiweekly Tax Deposits

The IRS requires all employment tax deposits to be made electronically using the Electronic Federal Tax Payment System (EFTPS). EFTPS is a free service provided by the Department of the Treasury and is accessible 24/7. Employers must enroll in EFTPS in advance to ensure timely payments.

Steps to Use EFTPS:

• Log in to your EFTPS account online.
• Select the tax form (typically Form 941).
• Enter the amount of tax being deposited.
• Select the correct tax period and payment date.
• Submit the payment before 8:00 p.m. ET the day before the due date for timely processing.

Timely electronic deposits help maintain compliance and provide an audit trail for employers and payroll providers.

Penalties for Late or Incorrect Deposits

Failing to deposit taxes on time or using the wrong deposit schedule can lead to costly penalties. The IRS imposes penalties based on how late the deposit is made:

• 1% for deposits made 1 to 5 days late
• 5% for deposits made 6 to 15 days late
• 10% for deposits more than 15 days late
• 15% for amounts not deposited within 10 days after the IRS issues a notice

In addition to penalties, interest may accrue on the unpaid amount. To avoid these consequences, employers must closely track payroll dates and align deposits with IRS rules.

Who Should Follow the Semiweekly Schedule?

Any employer who has a tax liability of more than $50,000 during the IRS-defined lookback period must follow the semiweekly deposit schedule. This usually includes:

• Mid-sized to large businesses with many employees
• Businesses with frequent payrolls (e.g., weekly or biweekly)
• Companies experiencing rapid growth in employment or wages

Employers new to the payroll process should monitor their liabilities carefully to determine whether they will be reclassified as semiweekly depositors in future years.

Tips for Managing the Semiweekly Deposit Schedule

Maintaining compliance with IRS deposit rules can be challenging, especially for busy employers. Here are some practical tips to stay on track:

Use Reliable Payroll Software

Modern payroll platforms can automate deposit scheduling and send reminders before due dates. They also ensure correct calculations for federal employment taxes.

Work with a Payroll Provider

Outsourcing payroll functions to a trusted provider can reduce errors and improve compliance. Most providers handle EFTPS payments directly on your behalf.

Create a Payroll Calendar

Set up a calendar with pay dates and corresponding deposit deadlines. Include reminders several days before each deposit is due to allow time for review and payment processing.

Review IRS Guidelines Annually

IRS deposit rules may change based on economic conditions or updates to Form 941. Stay informed by reviewing the latest IRS publications and updates each tax year.

Monthly vs. Semiweekly: Which Is Better?

Some employers may wonder whether the monthly schedule is more convenient. While monthly depositors benefit from fewer due dates, they must wait until the 15th of the following month to deposit taxes. On the other hand, the semiweekly schedule requires more frequent payments but aligns more closely with the business’s actual cash flow from payroll processing.

The IRS does not allow employers to choose their preferred schedule it is based strictly on tax liability during the lookback period. However, employers should view the semiweekly deposit schedule as a proactive way to manage cash, avoid large lump-sum payments, and stay compliant year-round.

The semiweekly tax deposit schedule plays a vital role in how larger employers manage their payroll tax responsibilities. While it demands careful planning and timely action, using tools like EFTPS, reliable payroll software, and consistent scheduling can make the process efficient and error-free. By understanding the IRS requirements and preparing in advance, businesses can ensure smooth tax operations and avoid unnecessary penalties.
