Most small employers land on a monthly deposit schedule, which means depositing payroll taxes by the 15th of the following month. If your lookback total tops $50,000, you move to a semiweekly schedule tied to your payday, with deposits due the following Wednesday or Friday. Either way, the deposit has to go through electronically, not by mail.
TL;DR:
- If your lookback total exceeds $50,000, you move from monthly to semiweekly deposits based on your previous year’s filings, regardless of pay frequency.
- Hitting $100,000 in tax in one day triggers an immediate deposit deadline the next business day and converts your status to semiweekly for over a year.
- Deposits must be made electronically through EFTPS, with same-day transfers up to $1 million accepted if submitted before 3:00 p.m. Eastern time.
- Employers should reconcile every payroll and deposit confirmation weekly to catch missed payments early and avoid penalties.
- Outsourcing deposit management to a virtual accounting service can reduce errors and ensure compliance during payroll growth.

What Is the IRS Deposit Schedule for Form 941?
The IRS does not let you pick your deposit schedule. It assigns one based on a lookback period, a four-quarter window running from July 1 of the second preceding year through June 30 of the preceding year. Add up the total tax reported on line 12 of your Form 941 returns filed during that window.
Report $50,000 or less during the lookback and you’re a monthly depositor. Report more than $50,000 and you’re bumped to semiweekly. New employers with no lookback history default to monthly status for their first calendar year, and employers who previously filed Form 944 follow a special lookback rule based on their prior-year Form 944 liability.
Before January 1 each year, confirm your status with a few quick steps:
- Pull line 12 totals from all four Form 941 returns in your lookback window.
- Add them together and compare the sum to the $50,000 line.
- Check whether you filed Form 944 in either lookback year, since that changes the calculation.
- Document your conclusion so you’re not guessing mid-quarter if the IRS ever asks.
A common misread here: employers assume how often they run payroll determines their schedule. It doesn’t. The lookback totals decide it, which is why a fast-growing business can jump from monthly to semiweekly without ever changing its pay frequency.
Monthly Schedule: What to Deposit and When
If you’re a monthly depositor, the rule is straightforward: deposit taxes for all paydays falling within a calendar month by the 15th day of the following month. Taxes withheld and owed for January paydays are due by February 15, for example, no matter how many pay runs happened that month.
A few things to keep in mind as you build your calendar:
- If the 15th lands on a weekend or a legal holiday recognized in the District of Columbia, the deposit is due the next business day.
- Every payday in the month gets bundled into one deposit, not deposited separately per pay run.
- If your total quarterly tax liability is under $2,500 and you haven’t triggered the next-day deposit rule, you can skip deposits and pay the balance when you file Form 941 instead.
Picture a business paying employees on the 5th and 20th of March. Both paydays’ taxes get combined into a single deposit due by April 15. Simple, until a holiday shifts the date. That’s where a payroll calendar or a service that tracks it for you earns its keep.
Semiweekly Schedule: Payday Mapping and Deposit Deadlines
Semiweekly depositors work off a payday map rather than a monthly cutoff, which trips up a lot of employers moving up from monthly status. The rule splits the week into two windows.
- Paydays falling on Wednesday, Thursday, or Friday require a deposit by the following Wednesday.
- Paydays falling on Saturday, Sunday, Monday, or Tuesday require a deposit by the following Friday.
- Each deposit period stands on its own, so a payday near the end of a quarter can create a separate deposit obligation even if the next payday falls just a few days later in the new quarter.
Say a business pays employees every other Friday. A Friday payday means the deposit is due the following Wednesday, four business days later. Switch that payday to a Monday instead, and the deposit deadline moves out to Friday of the same week. The day of the week the money hits employee accounts, not the pay period it covers, is what sets the clock.
$100,000 Trigger and the De Minimis Exception
One rule overrides every schedule: if you accumulate $100,000 or more in tax on any single day within a deposit period, you must deposit it by the next business day, no exceptions for weekends or your usual schedule. Monthly depositors who hit this threshold get reclassified as semiweekly depositors for the rest of that year and all of the next.
Statistic to remember: hitting the $100,000 mark isn’t just a bigger deposit. It permanently changes your status for over a year, which is why growing payrolls need active monitoring, not a once-a-quarter glance.
On the other end, the de minimis exception lets you skip deposits entirely if your total tax liability is under $2,500 for the current or prior quarter, and you never triggered the $100,000 rule.
A short monitoring routine catches both extremes:
- Log accumulated tax per payroll run once liabilities start climbing into the tens of thousands.
- Set an internal alert well before you approach $100,000.
- Reconcile every payroll run against your running quarterly total, not just at quarter-end.
How to Make Your Deposits (EFT, EFTPS, and Cutoffs)
Federal tax deposits have to be made electronically. Paper checks mailed to the IRS for Form 941 deposits are not accepted. The Electronic Federal Tax Payment System, or EFTPS, is the free Treasury-run system most small employers use, and same-day wire transfers exist as a backup option.
Timing matters here. EFTPS accepts same-day payments of $1 million or less if you submit before 3:00 p.m. Eastern time on a business day. Deposits above that amount carry earlier cutoffs, so larger payrolls need to plan further ahead.
Many employers hand this off to a bank or payroll provider authorized to deposit on their behalf, which is fine as long as you keep your own records to confirm it actually happened.
- Enroll in EFTPS directly, even if a payroll provider also deposits for you, so you always have visibility.
- Keep EFTPS confirmation numbers for every deposit, matched to the pay period they cover.
- Never assume a third party’s deposit went through without checking your own confirmation.
Pro Tip: Reconcile EFTPS confirmations against your payroll journal weekly, not quarterly. Catching a missed deposit within days is a fixable mistake; catching it three months later at Form 941 filing time is a penalty.
Deposits vs. Form 941 Filing: Don’t Confuse the Two
Deposits and filing run on separate clocks, and mixing them up is one of the more common ways employers end up with a failure-to-deposit penalty. Form 941 itself is due the last day of the month following the end of the quarter, but your deposits for taxes owed during that quarter are due far earlier, on the monthly or semiweekly schedule already covered.
Frequent errors worth checking for:
- Depositing based on the pay period covered instead of the actual payday, which shifts your deadline.
- Missing a next-day trigger because nobody was tracking accumulated tax between payrolls.
- Forgetting to reconcile total deposits made during the quarter against line 12 of Form 941 and Schedule B, where required.
When something doesn’t fit a standard case, Publication 15 (Circular E) has the full due-date tables, and the Form 941 instructions cover edge cases the general rules don’t.
When to Outsource Deposit Management
We’ve watched plenty of small business owners run monthly deposits smoothly until growth changes the math: more payroll runs, a payday that lands wrong two quarters in a row, or a sudden jump past the $100,000 trigger nobody was watching for. That’s usually the point where deposit management stops being a fifteen-minute task and starts becoming a liability.
A virtual accounting department handles EFTPS enrollment, builds your deposit calendar, reconciles every confirmation against payroll, and flags threshold triggers before they cause penalties. It’s the kind of oversight that keeps a growing payroll from quietly outgrowing your systems.
