The first year, nobody tells you. Tuition comes in — Venmo on Friday, a check on Monday, cash from the family that never quite got the app working — and every dollar of it lands in your account whole. No federal line taken out. No Social Security line. It feels like the cleanest money you've ever earned.
Then April arrives, your preparer runs the numbers, and there's a figure at the bottom of the page with four digits in it and a due date two weeks away.
That's the shock, and it's almost never because you did anything wrong. A job withholds tax from every paycheck on your behalf; self-employment doesn't. The obligation was accruing the whole time — you just weren't paying it as you went. This article is about how to pay as you go.
One thing up front, and it's not boilerplate: the right amount for you depends on your entire household return — a spouse's W-2 withholding, other income, credits, filing status, your deductions. This is general information, not tax advice. Get a preparer who has seen a family child care return before, ideally before your first filing, not after.
The part that shocks first-year providers: self-employment tax
Most people budget for income tax. Almost nobody budgets for the second tax sitting on top of it.
When you work for someone else, Social Security and Medicare come out of your paycheck — and your employer quietly pays a matching share you never see. When you work for yourself, you are both halves. That's self-employment tax, and per the IRS the rate is 15.3% of net self-employment earnings: 12.4% for Social Security and 2.9% for Medicare. It kicks in once your net earnings from self-employment reach $400, and it's calculated on Schedule SE, filed with your Form 1040.
This sits on top of ordinary federal income tax, which is why a provider in a modest bracket can still see a total bill far larger than her bracket suggests.
Two softeners worth knowing. SE tax is figured on your net earnings — profit after business deductions, not gross tuition collected — so every legitimate deduction reduces both taxes. And you can deduct the employer-equivalent portion of your SE tax when figuring adjusted gross income; that lowers income tax, not the SE tax itself.
The first of those is the whole argument for taking deductions seriously. For a home daycare the biggest one is usually the house itself, which runs through the time-space percentage that decides how much of your home counts as business use — and everything else flows from tracking expenses and receipts as they happen through the year rather than reconstructing them in March.
Who has to make estimated payments
The IRS rule is straightforward: you generally need to pay estimated tax if you expect to owe at least $1,000 for the year after subtracting withholding and refundable credits. A solo provider with 4–8 children and no other withholding in the household will almost certainly clear that.
If your spouse has a W-2 job, there's a second option: increasing their withholding on a Form W-4 to cover your daycare income instead of writing quarterly checks yourself. Withholding counts as paid evenly across the year, which makes it forgiving in a way quarterly payments aren't. For some households it removes the chore entirely — worth asking your preparer.
The four payment periods (and why they aren't quarters)
They're called quarterly payments, but the periods are famously uneven. Here's the actual structure the IRS uses:
| Income earned during | Payment normally due |
|---|---|
| Jan 1 – Mar 31 | April 15 |
| Apr 1 – May 31 | June 15 |
| Jun 1 – Aug 31 | September 15 |
| Sep 1 – Dec 31 | January 15 of the following year |
Look at the second and third rows. Period two covers two months; period three covers three. That's not a typo you can ignore — the June payment arrives faster than you expect, and it's the one providers most often miss.
Dates shift when they land on a weekend or holiday. Per the IRS, if a due date falls on a Saturday, Sunday, or legal holiday, the payment is on time if you make it on the next day that isn't one of those. So don't memorize the four dates as gospel — check the current year on irs.gov each January, or have your preparer hand you that year's dates.
Safe harbor: how to stop worrying about being exactly right
The underpayment penalty is what makes estimated tax stressful. You don't know your final number in June, so how can you pay the right amount? You don't have to. The IRS provides a safe harbor: generally, you avoid an underpayment penalty if your withholding and estimated payments for the year total at least the smaller of
- 90% of the tax shown on your current year's return, or
- 100% of the tax shown on your prior year's return — 110% if your adjusted gross income that prior year was greater than $150,000.
That second option is the useful one, because it's a number you already know. Take last year's total tax, divide by four, pay that on each due date, and you've generally protected yourself from the penalty even if this year turns out much better than last. You'll still owe the difference at filing — safe harbor prevents the penalty, not the balance — but a known bill in April beats a bill plus a penalty.
Two caveats. Safe harbor based on the prior year assumes you actually filed a prior-year return covering twelve months. And the penalty is figured period by period on Form 2210, so paying the full year's worth in December doesn't undo three missed deadlines. Steady beats heroic. For the full mechanics of how that penalty actually gets calculated and what to do if you've already missed a payment, see our underpayment penalty guide. And if your income genuinely drops mid-year — a family withdraws unexpectedly and doesn't come back — the even four-way split isn't your only option; see our guide to adjusting a remaining quarterly payment after a real income drop.
The habit that makes this painless: skim every payment as it arrives
Here's the practical version, and it costs about fifteen seconds per payment.
When a family's tuition lands, immediately move a fixed percentage of it into a separate savings account. You do not touch that account except to pay the IRS.
That's it. No forecasting, no spreadsheet. The money is skimmed before it ever feels like yours — exactly how withholding works for everyone else.
The percentage is the part you cannot copy off the internet, because it depends on your deductions, your state, and your household's other income. Ask your preparer for your number. Until then, a working estimate: divide last year's total tax by last year's gross tuition collected, and you have the share of every dollar that actually went to tax. Skim that, plus a couple of points of cushion.
Worked example, entirely illustrative: say your preparer tells you to set aside 25 cents of every tuition dollar. A family pays $250 for the week; $62.50 goes straight to the tax account, $187.50 stays. Do that on every payment for a full quarter and the due date is a non-event — the money's already sitting there. The 25% is a stand-in, not a recommendation. Your number could be meaningfully lower or higher.
Two things make the habit stick. First, a dedicated place to skim into — which is far easier when tuition isn't landing in the same checking account as the grocery money, and is the main reason to open a separate business bank account for the daycare. Second, knowing precisely what came in and when. If some tuition arrives through Venmo, Zelle, or Cash App, also read up on how 1099-K reporting from payment apps works — a form filed to the IRS about your deposits is a bad time to discover your records don't match.
How to actually pay
Paying is the easy part now. Through irs.gov you can:
- Sign in to your IRS Online Account and pay directly (it also shows what you've already paid this year, which is useful when you can't remember whether June happened)
- Use IRS Direct Pay from a checking or savings account
- Enroll in EFTPS, the Electronic Federal Tax Payment System — enrollment takes a few days, so don't start it the night before a deadline
- Pay by debit or credit card through an IRS-approved processor, which charges a fee
- Mail a check with the Form 1040-ES voucher
Whichever you pick, save the confirmation with the rest of your tax records, labeled with the period it covers.
Don't forget your state. Most states with an income tax run their own estimated payment system, with its own due dates and rules. Paying the IRS does not cover it.
A simple annual rhythm
- January — look up this year's four due dates on irs.gov; set a phone alert a week ahead of each
- January — ask your preparer for your set-aside percentage for the year
- Every payment, all year — skim that percentage into the tax account the day it arrives
- Each due date — pay federal, pay state, save both confirmations
- At filing — compare what you paid to what you owed, and adjust next year's percentage
Where DaycareFlow fits
DaycareFlow is not tax software. It doesn't calculate your estimated payments, it doesn't file anything, and it won't replace your preparer.
What it does is fix the input problem underneath all of this. Your set-aside percentage is worthless if you don't know what actually came in. DaycareFlow keeps each child's billing rate and frequency on their profile, tracks paid versus unpaid on a dashboard, and holds a per-child billing record — so when you sit down to figure out what a quarter actually brought in, you're reading a record instead of scrolling three payment apps and a notebook. Automated payment reminders and one-click year-end statements are coming.
And the cleanest tax year is the one where the money showed up on time in the first place. That's the problem we built for.

Frequently asked questions
Do home daycare providers have to pay quarterly taxes?
Generally yes, if you expect to owe at least $1,000 in tax for the year after withholding and refundable credits. Most solo providers with no other withholding in the household clear that easily. If your spouse has a W-2 job, increasing their withholding is sometimes an alternative to writing quarterly payments yourself — ask your preparer which fits your return.
What percentage of daycare income should I set aside for taxes?
There's no universal number, because it depends on your deductions, your state, your filing status, and any other household income. The most reliable way to build your own figure is to divide last year's total tax by last year's gross tuition, then add a small cushion. Ask your tax preparer to confirm the percentage before you rely on it.
What happens if I miss a quarterly estimated tax payment?
You may owe an underpayment penalty, which the IRS figures period by period on Form 2210 — so catching up later in the year doesn't fully erase a missed deadline. Pay as soon as you realize, and pay the remaining periods on time. If the miss was caused by a casualty, disaster, or similar circumstance, ask your preparer about penalty waiver relief.
What is self-employment tax and why do I owe it on daycare income?
Self-employment tax covers your Social Security and Medicare contributions as both employee and employer. The IRS sets the rate at 15.3% — 12.4% Social Security plus 2.9% Medicare — on net self-employment earnings, and it applies once those earnings reach $400. It's calculated on Schedule SE and sits on top of ordinary income tax, which is why first-year providers are often surprised by the total.
How do I pay estimated taxes to the IRS?
Through irs.gov you can pay from your IRS Online Account, use IRS Direct Pay from a bank account, enroll in EFTPS, pay by debit or credit card through an approved processor for a fee, or mail a check with a Form 1040-ES voucher. Save every confirmation with your tax records, and remember to check whether your state requires its own separate estimated payments.
