If you freelance or run a small side business in the US, the IRS expects four estimated tax payments a year instead of one big bill in April. Missing a due date is the single most common way freelancers rack up penalties, and it is fully preventable. The fix has two parts: schedule all four payments through EFTPS once, at the start of the year, and set up an automatic transfer that pulls a fixed percentage of every incoming payment into a dedicated tax account. Do both and the quarterly deadline stops being a scramble — the payment is already scheduled, and the money is already sitting there waiting.
What Is EFTPS, and Do You Need It?
EFTPS (the Electronic Federal Tax Payment System) is the US Treasury's free system for paying federal taxes online or by phone. It is not a private app and it does not have a subscription fee — it is a government service, and every freelancer who owes estimated tax should have an account. If you already mail checks or pay through your tax software each quarter, EFTPS replaces that with four payments you schedule once and then forget about until the money leaves your account.
You need three things before you start: your Social Security number or EIN, your bank's routing and account number, and about 15 minutes, because EFTPS mails a PIN to your address on file before you can log in and schedule payments. Enroll at least two weeks before your first quarterly deadline so the PIN has time to arrive.
What Are the 2026 Quarterly Estimated Tax Deadlines?
The IRS splits the year into four uneven periods, not four equal quarters:
| Payment period | Due date |
|---|---|
| Jan 1 – Mar 31 | April 15 |
| Apr 1 – May 31 | June 16 |
| Jun 1 – Aug 31 | September 15 |
| Sep 1 – Dec 31 | January 15 (following year) |
When a due date lands on a weekend or federal holiday, it rolls to the next business day — check the current-year dates on IRS.gov before you schedule, since they shift slightly from year to year.
How Do You Schedule All Four Payments in EFTPS at Once?
This is the worked example: once your EFTPS account is active, you can queue every payment for the year in a single sitting instead of logging back in four times.
- Log in to EFTPS.gov with your PIN and internet password.
- Select Payments, then Make a Payment.
- Choose tax form 1040ES (individual estimated tax) and tax type Estimated.
- Enter the payment amount for the first period (see the set-aside math below) and set the settlement date to the due date itself, or one to two business days earlier so it clears in time.
- Confirm, then repeat steps 3 and 4 for the remaining three due dates, entering each period’s amount and its own settlement date.
- Save or screenshot the four confirmation (EFT) numbers EFTPS gives you — that is your paper trail if a payment ever needs tracing.
Because each payment schedules independently, you can queue all four in about ten minutes and then not touch EFTPS again until the amounts need adjusting, for example after a strong quarter.
How Much Should You Set Aside From Each Payment?
The number that trips people up is not the tax rate itself — it is remembering to move money before it feels spent. A commonly used starting point for freelancers is to set aside 25–30 percent of every payment you invoice: roughly 15.3 percent covers self-employment tax (Social Security and Medicare), and the remaining 10–15 percent covers federal income tax at typical freelance income levels. State income tax, where it applies, is on top of that.
Worked example: you invoice a client for $4,000. At a 28 percent set-aside rate, $1,120 moves to your tax account the day the payment clears, leaving $2,880 as spendable income. Repeat that math on every invoice and the quarterly payment amount is just whatever accumulated in that account since the last due date — no separate estimate needed.
If your income varies a lot quarter to quarter, use the IRS Form 1040-ES worksheet once a year to sanity-check the percentage against your actual bracket, then keep using the same flat rate for automation. Precision here matters less than consistency, because the goal is to never be caught short.
How Do You Automate the Set-Aside Transfer?
Most online business banks let you set a recurring transfer rule or a second sub-account earmarked for taxes; a few can split an incoming deposit automatically. Set up whichever version your bank supports:
- Automatic split at deposit (if your bank offers it): configure the rule to route a fixed percentage of every incoming deposit to a separate tax savings account the moment it clears.
- Scheduled recurring transfer (works with any bank): if your income is fairly steady, set a recurring transfer for a flat dollar amount on the same day each week or month, sized to your average invoice volume times your set-aside percentage.
- Manual-but-triggered (the fallback): if your bank supports neither, pair a calendar reminder with your invoicing tool’s “payment received” notification, so the transfer happens the same day money arrives instead of drifting to whenever you remember.
Whichever method you use, name the destination account something unambiguous, like "Taxes — do not spend," so it does not get pulled into everyday spending decisions.
If you are already automating other parts of your freelance admin — invoicing, client onboarding, follow-ups — the same trigger-based thinking applies here. 15 Workflow Automations That Save Solopreneurs 5 Hours a Week covers more of these payment- and invoice-triggered setups if you want to extend the same pattern past taxes.
What Happens If You Miss a Payment or Underestimate?
The IRS charges an underpayment penalty calculated on however much you owed and how late you paid it — it is not a flat fee, and it compounds the longer a shortfall sits. There is a built-in safety net called the safe harbor rule: if your total withholding and estimated payments for the year equal at least 100 percent of last year's tax bill (110 percent if last year's adjusted gross income was over $150,000), you generally avoid the penalty even if you end up owing more at filing time. Aiming your set-aside percentage at last year's effective tax rate, rather than trying to predict this year's income exactly, is the simplest way to stay inside that safe harbor.
If you do miss a due date, pay as soon as you notice rather than waiting for the next quarter — the penalty calculation runs by day, so a payment made two weeks late costs less than one made two months late.
What If Your Income Is Irregular From Month to Month?
A flat percentage set-aside still works with irregular income, because it scales with whatever comes in rather than assuming a steady paycheck. The part that needs adjusting is the recurring-transfer method: if some months bring in $10,000 and others bring in $1,500, a fixed weekly transfer amount will overshoot in slow months and undershoot in busy ones. Two adjustments handle this:
- Prefer split-at-deposit over a flat recurring amount whenever your bank supports it, since a percentage of each deposit tracks actual income instead of an average.
- Recheck the running total against the upcoming due date about two weeks out, and top up the tax account manually if a big invoice landed outside the automated rule, for example a one-off project paid by wire transfer instead of your usual invoicing tool.
If you also draw a mix of 1099 freelance income and a W-2 paycheck with withholding, the safe-harbor math changes slightly: withholding from the W-2 job counts toward your total for the year even though it is not an estimated payment. In that case, treat the set-aside percentage as covering the 1099 income only, and use the prior-year safe-harbor comparison (100 or 110 percent of last year's total tax) to check whether your W-2 withholding plus your quarterly payments together clear the bar.
Common Mistakes That Undo the Automation
The system above only works if a few details are handled up front:
- Scheduling the EFTPS settlement date exactly on the due date, with no buffer. Bank transfers can take one to two business days to post. Set the settlement date one to two business days ahead of the actual deadline so the payment still counts as on time even if a bank holiday slows things down.
- Treating the tax sub-account as untouchable. The most common way this breaks is dipping into the tax account during a slow month “temporarily.” If cash flow is genuinely tight, lower the set-aside percentage deliberately and recalculate, rather than borrowing from an account that already has a due date attached to it.
- Forgetting to re-enroll payments for the next tax year. EFTPS does not automatically roll last year’s four scheduled payments into the new year — queue the next year’s four dates and amounts once you have a rough income estimate for the year ahead, ideally in the same sitting as your fourth-quarter payment.
- Assuming EFTPS covers state estimated tax. EFTPS is federal only. If your state has its own income tax, check whether your state’s department of revenue offers a similar online scheduling system, and set aside a separate percentage for it, since the state due dates do not always match the federal ones exactly.
Keeping the System Running
Once EFTPS has all four dates queued and your bank is routing a percentage of every deposit into the tax account, the only recurring task left is a five-minute check each quarter: confirm the scheduled amount still matches what has accumulated, and adjust it up or down if the quarter ran heavier or lighter than usual. If you track recurring admin tasks like this one in a notes system, a simple linked-notes setup works well for a running log of due dates and amounts — see How to Use Obsidian: A Beginner’s Guide to Linked Notes for a beginner walkthrough of setting that up.
None of this requires new software or a subscription. It requires ten minutes in EFTPS, one rule in your bank's online settings, and a habit of letting the money move before you see it as spendable. That is the whole system.
