Your deposit schedule depends on how much you owe and what legal structure your business has

The IRS does not give every employer the same payroll tax deposit schedule. Instead, your schedule is determined by two things: the total amount of payroll taxes you owe in a given period, and whether you are classified as a monthly or semi-weekly depositor. The IRS assigns you to one category or the other based on your lookback period — a specific 12-month window of your past tax liability that the agency examines each year. If you deposited less than $50,000 in payroll taxes during your lookback period, you deposit monthly. If you deposited $50,000 or more, you deposit semi-weekly. This information happens automatically; you do not choose your schedule.

Your deposit schedule also depends on what day of the week you pay your employees. Semi-weekly depositors follow a Wednesday/Friday rule: if you pay employees on Wednesday, Thursday, or Friday, you deposit by the following Wednesday. If you pay on Saturday, Sunday, Monday, or Tuesday, you deposit by the following Friday. Monthly depositors have until the 15th of the following month. Understanding which category you fall into prevents penalties and keeps your account in good standing with the IRS.

Key Takeaways

  • The IRS determines your deposit schedule using a lookback period — the 12 months ending June 30 of the prior year — and assigns you as either monthly or semi-weekly based on total taxes owed during that period.
  • If your lookback period taxes were under $50,000, you are a monthly depositor and must pay by the 15th of the following month; if $50,000 or more, you are semi-weekly and must pay within one or two business days depending on your payroll day.
  • The IRS notifies you of your deposit schedule in writing, usually in December or January, and the schedule remains in effect for the entire calendar year unless you cross the $50,000 threshold mid-year.
  • If you owe $100,000 or more on any single day, you must deposit by the next business day, regardless of whether you are normally monthly or semi-weekly.
  • New employers are treated as monthly depositors until the IRS assigns them a schedule based on their first lookback period.

How the IRS lookback period works

The lookback period is a fixed 12-month window that runs from July 1 through June 30. The IRS uses the lookback period ending June 30 of the prior year to determine your deposit schedule for the current calendar year. For example, to determine your 2024 deposit schedule, the IRS looks at your payroll tax liability from July 1, 2022, through June 30, 2023. This means your 2024 schedule is already set before 2024 begins.

The IRS adds up all federal income tax withholding, Social Security tax, and Medicare tax you deposited during that 12-month window. If the total is less than $50,000, you are assigned a monthly schedule for the entire following calendar year. If the total is $50,000 or more, you are assigned a semi-weekly schedule. This assignment is automatic — the IRS does not ask your permission or give you a choice. The agency notifies you of your schedule in writing, usually in a letter sent in December or January before the year begins.

Monthly depositors and the 15th of the month rule

If you are a monthly depositor, you deposit all payroll taxes owed for a calendar month by the 15th of the following month. For example, all taxes withheld and owed in January must be deposited by February 15. All taxes owed in December must be deposited by January 15 of the next year. The deposit covers federal income tax withholding, your share of Social Security tax, your share of Medicare tax, and the employee's share of Social Security and Medicare that you withheld from their paychecks.

Monthly depositors typically have smaller payrolls or lower overall tax liability. The once-a-month schedule gives you more time to gather funds and process the deposit. However, if at any point during the year your accumulated tax liability reaches $100,000 or more on a single day, you must deposit that amount by the next business day, even if you are normally a monthly depositor. This is called the $100,000 rule, and it overrides your normal schedule.

Semi-weekly depositors and the Wednesday/Friday rule

If you are a semi-weekly depositor, your deposit important date depends on which days of the week you pay your employees. The IRS uses a Wednesday/Friday rule: if you pay employees on Wednesday, Thursday, or Friday, you must deposit payroll taxes by the following Wednesday. If you pay on Saturday, Sunday, Monday, or Tuesday, you must deposit by the following Friday. This means you may deposit twice in one week or once every two weeks, depending on your payroll schedule.

Semi-weekly depositors typically have larger payrolls or higher overall tax liability. The more frequent deposit schedule keeps large tax amounts moving to the IRS quickly. Like monthly depositors, semi-weekly depositors are also subject to the $100,000 rule: if your tax liability reaches $100,000 or more on any single day, you must deposit by the next business day, regardless of your normal semi-weekly schedule.

The $100,000 rule and next-business-day deposits

The $100,000 rule applies to all employers, whether monthly or semi-weekly. If your accumulated payroll tax liability reaches $100,000 or more on any single day during a deposit period, you must deposit that amount by the next business day. This rule exists to prevent large amounts of tax money from sitting in your account instead of the IRS's account.

The next business day means the next calendar day that is not a Saturday, Sunday, or federal holiday. If you hit $100,000 on a Friday, your next business day is Monday (unless Monday is a federal holiday). If you hit $100,000 on a Thursday, your next business day is Friday. This rule overrides your normal monthly or semi-weekly schedule entirely. Once you deposit the $100,000, you return to your regular schedule for the remainder of that deposit period.

How new employers are classified

If you are a new employer and have not yet completed a lookback period, the IRS treats you as a monthly depositor until you have 12 months of payroll history. Once your first lookback period ends (June 30 of your first full year in business), the IRS examines your tax liability during that period and assigns you a permanent schedule starting the following January.

Some new employers grow quickly and cross the $50,000 threshold before their first lookback period ends. Even so, you remain a monthly depositor for that first year. Your schedule will change to semi-weekly the following January if your lookback period total was $50,000 or more. If you are unsure whether you are monthly or semi-weekly, check the IRS letter you received when you opened your business account, or contact the IRS at 1-800-829-1040.

When your schedule changes mid-year

Your deposit schedule is set for the entire calendar year based on your lookback period. However, if you accumulate $50,000 or more in payroll taxes during the current year before your normal schedule change date (January 1), you become a semi-weekly depositor when ready. This is called becoming a semi-weekly depositor during the year. The IRS sends you a notice when this happens, and you must switch to semi-weekly deposits right away.

Once you become semi-weekly mid-year, you remain semi-weekly for the rest of that year and the following year. You do not revert to monthly even if your lookback period the following June 30 shows less than $50,000. You stay semi-weekly until a future lookback period shows less than $50,000, at which point you return to monthly the following January. This rule prevents employers from gaming the system by timing deposits strategically.

How to find out your current deposit schedule

The IRS notifies you of your deposit schedule in writing, usually in a letter sent in December or January. This letter states whether you are a monthly or semi-weekly depositor for the coming year. If you have lost that letter or are unsure of your status, you can find your schedule in several places. Log into your IRS online account at IRS.gov using your employer identification number (EIN). You can also call the IRS at 1-800-829-1040 and speak to a representative, or check any recent Form 941 (Employer's Quarterly Federal Tax Return) you filed — your deposit schedule should be noted on that form.

Your payroll software may also display your deposit schedule. Most modern payroll platforms — including ADP, Gusto, Paychex, and QuickBooks Payroll — allow you to enter your deposit schedule, and the software will calculate your deposit due dates automatically. If your software does not show your schedule, contact your payroll provider or the IRS directly. Knowing your correct schedule prevents missed deposits and penalties.

Frequently Asked Questions

What happens if I deposit on the wrong schedule?

Late deposits result in a failure-to-deposit penalty. The penalty ranges from 2% to 15% of the unpaid tax, depending on how late the deposit is. A deposit one to five days late incurs a 2% penalty; six to 15 days late is 5%; and more than 15 days late is 10%. If the IRS has to pursue collection, the penalty can reach 15%. Depositing early never triggers a penalty.

Can I request to change my deposit schedule?

No. The IRS assigns your schedule based on your lookback period, and you cannot request a different one. Your schedule changes automatically each January based on your prior lookback period. If you believe the IRS made an error in assigning your schedule, contact them at 1-800-829-1040 with documentation of your lookback period taxes.

Do I deposit payroll taxes the same way for federal, state, and local taxes?

No. Your federal payroll tax deposit schedule is determined by the IRS rules described here. State and local payroll taxes follow separate schedules set by your state and local tax agencies. You may owe state taxes monthly and federal taxes semi-weekly, or vice versa. Check with your state revenue department and local tax authority for their specific schedules.

What if I have multiple businesses — do I combine their tax liability for the lookback period?

Yes. If you own multiple businesses that share the same EIN, the IRS combines their tax liability for the lookback period. If you own separate businesses with separate EINs, each business has its own lookback period and deposit schedule. Sole proprietors with a single EIN but multiple business activities must combine all activities when calculating their lookback period.

If I am semi-weekly, do I have to deposit twice every week?

Not necessarily. Semi-weekly means you deposit up to twice per week, depending on when you pay employees. If you pay employees only once per week, you deposit once per week on your designated day (Wednesday or Friday). If you pay twice per week, you may deposit twice per week. Your actual deposit frequency depends on your payroll frequency, not on your semi-weekly status.
