When Are Quarterly Estimated Taxes Due in 2025?
The Four Quarterly Due Dates for 2025
Despite the name “quarterly,”. The four payment periods aren’t evenly spaced. The first two are only two months apart. Here are the 2025 deadlines (per IRS Form 1040-ES instructions):
- Q1 — April 15, 2025: Covers income earned January 1 through March 31
- Q2 — June 16, 2025: Covers income earned April 1 through May 31 (yes, just two months)
- Q3 — September 15, 2025: Covers income earned June 1 through August 31
- Q4 — January 15, 2026: Covers income earned September 1 through December 31
June 15 falls on a Sunday in 2025, so the Q2 deadline shifts to Monday, June 16. All other dates land on weekdays and stand as listed.
The Q4 payment is technically for 2025 income, but it’s not due until January 15 of the following year. If you file your 2025 tax return and pay any remaining balance by February 1, 2026, you can skip the Q4 estimated payment entirely — but that’s a tight turnaround. Most people just pay the estimate in January.
Who Needs to Make Estimated Payments
The general rule per IRC §6654: if you expect to owe $1,000 or more in federal tax after subtracting withholding and credits, you need to make estimated payments. That catches a lot of people who don’t think of themselves as “quarterly filers.”
The obvious group is self-employed individuals — freelancers, consultants, sole proprietors, single-member LLC owners. You have no employer withholding taxes for you, so estimated payments are your substitute.
But plenty of W-2 employees need to pay quarterly too. If you have significant investment income (dividends, capital gains, interest), rental income, or a side business, your W-2 withholding probably doesn’t cover the full tax on everything. A teacher who earns $30,000 in rental income on the side isn’t going to have tax withheld on those rents unless they adjust their W-4.
Retirees with pension income and Social Security benefits sometimes need estimated payments if their withholding elections don’t cover the tax. Partners and S-corp shareholders receiving K-1 income almost always do.
High-income W-2 earners are another group that gets caught. If you earn $400,000 in salary and your withholding is set to cover that amount, but you also realize $100,000 in capital gains from stock sales, the withholding won’t cover the gains. The IRS doesn’t care that you didn’t know about the gains until December — they want quarterly payments.
The Safe Harbor Rules: How to Avoid Penalties
You won’t owe an underpayment penalty if your estimated payments (plus any withholding) meet one of these two tests (per IRC §6654(d)):
- 90% of current-year tax: Your total payments cover at least 90% of the tax shown on your 2025 return.
- 100% of prior-year tax: Your total payments equal at least 100% of the tax shown on your 2024 return. This jumps to 110% if your 2024 adjusted gross income exceeded $150,000 ($75,000 if married filing separately).
The prior-year safe harbor is the one most people rely on. If you owed $30,000 in federal tax for 2024 and your AGI was over $150,000, you need to pay at least $33,000 (110%) in estimated payments and withholding during 2025 to avoid penalties. Even if your actual 2025 tax turns out to be $50,000, you won’t owe an underpayment penalty as long as you hit the $33,000 threshold.
This is the most common planning strategy for people with unpredictable income. You can’t know in April what your capital gains will be in October. But you can look at last year’s return, calculate 110%, divide by four, and send those payments. Anything else you owe gets settled at filing time — penalty-free.
How to Calculate Your Estimated Tax Using Form 1040-ES
The IRS publishes Form 1040-ES with a worksheet for calculating estimated payments. The basic process:
Start with your expected adjusted gross income for 2025. Subtract your expected deductions (standard or itemized). That gives you estimated taxable income. Apply the tax brackets. Add self-employment tax if applicable. Subtract expected credits (child tax credit, education credits, etc.). The result is your estimated total tax.
Now subtract any withholding you expect from W-2 jobs or other sources. The remaining amount is what you owe in estimated payments. Divide by four for equal quarterly installments.
The worksheet is straightforward for people with stable income. For freelancers whose income swings wildly from quarter to quarter, the worksheet can feel like guessing. If that’s you, the prior-year safe harbor is your friend — or consider the annualized income installment method, which we’ll cover below.
How to Pay: EFTPS, Direct Pay, and Other Options
You’ve got several ways to send estimated tax payments to the IRS:
- IRS Direct Pay (irs.gov/payments): Free. Pay directly from your bank account. No registration required. Select “Estimated Tax”. And the correct tax year. You get immediate confirmation.
- EFTPS (Electronic Federal Tax Payment System): Free. Requires enrollment (takes about a week to set up). Allows scheduling payments in advance. This is what most businesses use, and it works for individuals too.
- Credit or debit card: You can pay through IRS-approved processors, but they charge a fee — typically 1.85% to 1.98% for credit cards or a flat fee around $2.50 for debit cards. Only makes sense if you’re earning rewards that exceed the fee.
- Check or money order: Mail to the IRS with a 1040-ES voucher. Slow, no confirmation until your check clears, and the IRS can lose mail. We don’t recommend this unless you have no other option.
For most people, IRS Direct Pay is the simplest choice. You can even set it up the morning a payment is due and still make the deadline.
State Estimated Taxes: Don’t Forget Those
Federal estimated payments are only half the picture. Most states with an income tax have their own quarterly estimated tax requirements with their own due dates, which don’t always match the federal schedule.
New York: NYS estimated tax due dates generally follow the federal schedule (April 15, June 15, September 15, January 15). Pay through the NYS Tax Department website. If you live in NYC, your state estimated payment covers both NYS and NYC income tax — there’s no separate city payment.
California: California uses a different payment schedule: 30% due April 15, 40% due June 16, 0% due September 15 (yes, zero), and 30% due January 15. This trips up California taxpayers who assume it mirrors the federal 25/25/25/25 split. Pay through the FTB website.
Florida, Texas, Nevada and other no-income-tax states: No state estimated payments required. One less thing to track.
If you live in one state and work in another, you may owe estimated payments to both. Remote work has made this even more complicated since 2020.
What Happens If You Underpay
The underpayment penalty is calculated on Form 2210 and works like interest on the amount you should have paid but didn’t. It’s not a flat penalty — it’s applied quarter by quarter based on the federal short-term interest rate plus 3 percentage points. For 2025, that rate is around 7-8%, which makes underpayment penalties more expensive than they’ve been in years.
The penalty applies even if you get a refund. You could owe $40,000 total, make no estimated payments all year, then pay $45,000 when you file and get a $5,000 refund — and still owe an underpayment penalty on each quarter where your cumulative payments were short.
The IRS calculates the penalty automatically when you file, or you can calculate it yourself on Form 2210. Some people choose to accept the penalty intentionally, treating it as the cost of borrowing from the government. At 7-8%, that’s not cheap money, but it’s better than the interest on some credit cards.
The Annualized Income Installment Method
If your income is heavily concentrated in one part of the year — maybe you’re a real estate agent who closes most deals in Q2 and Q3, or a freelancer who lands a big contract in October — the standard equal-payment approach can create penalties for quarters where you genuinely had little income.
The annualized income installment method (Schedule AI of Form 2210) lets you calculate each quarter’s required payment based on the income you actually earned through the end of that quarter, annualized. If you earned almost nothing in Q1, your required Q1 payment is small — even if your total annual income ends up being $300,000.
The math is tedious. You’re essentially preparing four partial-year tax calculations. Most tax software handles it automatically once you indicate you want to use the annualized method. It’s worth the effort for anyone whose income is genuinely uneven across quarters. For freelancers with steady monthly income, the standard method is simpler and works fine.
An Alternative: Adjust Your W-4 Withholding
If you have a W-2 job in addition to self-employment or investment income, there’s a simpler approach than writing four quarterly checks. Increase your W-4 withholding to cover the extra tax. The IRS treats W-2 withholding as paid evenly throughout the year, even if you increase it in December. That’s an advantage over estimated payments, which are assigned to specific quarters.
Here’s what that looks like in practice: you realize in November that you owe $20,000 more than you’ve paid so far. If you send that as a Q4 estimated payment, the IRS could still penalize you for underpaying Q1 through Q3. But if you ask your employer to withhold an extra $20,000 from your remaining paychecks, the IRS treats it as if $5,000 was withheld in each quarter. No underpayment penalty.
This only works if you have W-2 income. And your employer has to be willing to process the increased withholding quickly. But it’s a legitimate — and often overlooked — way to fix a late-year estimated tax shortfall. Talk to your tax preparer about whether it makes sense for your situation.

Frequently Asked Questions
When are quarterly estimated taxes due in 2025?
The four 2025 quarterly estimated tax due dates are April 15, June 16, September 15, and January 15, 2026. You’ll use Form 1040-ES to calculate and submit each payment. These dates cover income earned in unequal periods — Q1 covers January through March, Q2 covers April and May, Q3 covers June through August, and Q4 covers September through December.
Here’s what most people miss: the periods aren’t equal quarters. Q2 is only two months long, which means if you had a strong April or May, you might underpay and not realize it until September. Also, if you live in New York City, you’ve got a city-level estimated tax on top of federal and New York State payments — all three run on different calculation methods. NYC residents with significant self-employment income can face a combined marginal rate north of 50% when you stack federal, state (up to 10.9% under current law), and NYC (up to 3.876%) taxes together.
At The Reed Corporation, we map out all three sets of due dates for NYC clients at the start of the year so nothing sneaks up on anyone. If your income varies month to month — which is common for consultants, freelancers, and business owners — we’ll recalculate estimated payments each quarter using the annualized income installment method under IRC §6654(d)(2) to avoid overpaying early in the year.
What happens if I miss a quarterly estimated tax payment?
Missing or underpaying a quarterly estimated tax payment triggers an underpayment penalty under IRC §6654. For 2025, the IRS penalty rate is 8% per annum on the underpaid amount — that rate adjusts quarterly based on the federal short-term rate plus 3 percentage points. The penalty accrues from the missed due date through either the date you pay or April 15, 2026, whichever comes first. It’s not a one-time fine; it compounds daily.
The exception most people don’t know about is the safe harbor rule. If you pay at least 100% of your prior-year tax liability (or 110% if your 2024 adjusted gross income exceeded $150,000), you won’t owe any underpayment penalty — even if you end up owing a lot in April. There’s also a waiver available under IRC §6654(e)(3) if the underpayment was due to casualty, disaster, or other unusual circumstances. New York State has its own penalty structure under Tax Law §685(c), and it doesn’t automatically mirror the federal safe harbor thresholds.
If you got hit with a penalty last year and want to make sure it doesn’t happen again in 2025, that’s exactly the kind of thing we sort out early. The Reed Corporation reviews prior-year returns to establish the right safe harbor target, then builds a payment calendar so clients aren’t scrambling every quarter to figure out what they owe.
Do I have to pay quarterly estimated taxes if I’m self-employed?
Yes, almost certainly. The IRS requires quarterly estimated tax payments if you expect to owe at least $1,000 in federal income tax for the year after subtracting withholding and credits — and most self-employed people clear that threshold quickly. Self-employment tax alone (currently 15.3% on net earnings up to $176,100 in 2025, and 2.9% above that) can push you past $1,000 before you’ve even factored in income tax. New York State’s threshold is lower — just $300 in expected state tax liability triggers quarterly requirements.
What a lot of freelancers and sole proprietors get wrong is thinking that paying once a year in April is fine as long as they eventually pay. It’s not. The penalty isn’t about being late on your annual return — it’s about not paying enough throughout the year, period. Even if you file on time and pay in full on April 15, you can still owe an underpayment penalty for Q1 through Q3. The IRS treats each quarter independently. Missing Q1 alone can generate a penalty even if you overpay in Q4.
Self-employed clients who come to The Reed Corporation usually start with a clean income-and-expense projection in January or February. We establish their estimated payment schedule before the April 15 Q1 deadline, then revisit the numbers after Q2 closes in June — because income rarely looks the same at midyear as it did in January.
How do I calculate how much to pay for quarterly estimated taxes?
There are two main methods. The simplest is the prior-year safe harbor: pay at least 100% of your total 2024 tax liability in equal installments across four quarters (or 110% if your 2024 AGI topped $150,000). The second method is the current-year method — estimating your 2025 income, deductions, and credits, then calculating 90% of what you expect to owe and spreading that across the four payment dates. Either method works; the goal is just to avoid the IRC §6654 underpayment penalty.
The part most people miss is that the current-year 90% method can actually save you real money if your income dropped from last year. Paying 110% of a high-income prior year when this year’s income is lower means you’ve given the IRS an interest-free loan. On the flip side, if your income is spiking this year, the prior-year safe harbor protects you from penalties even if your April bill ends up being large. You need to run both scenarios to see which one makes more financial sense in your specific situation.
The Reed Corporation runs this comparison for every client with variable income. We also account for New York City and State estimated tax calculations at the same time, since the state uses Form IT-2105 and has its own thresholds and annualization rules. Getting all three right — federal, state, and city — is where most people need help, and it’s a core part of what we do for self-employed and business-owner clients in NYC.
Are the 2025 quarterly tax due dates different because of holidays or weekends?
One of the 2025 dates actually does shift. The standard Q2 deadline of June 15 falls on a Sunday, so it moves to Monday, June 16, 2025. The other three dates land on weekdays: April 15 (Tuesday), September 15 (Monday), and January 15, 2026 (Thursday). These adjustments follow the standard IRS rule under IRC §7503 — when a due date falls on a Saturday, Sunday, or federal legal holiday, it automatically moves to the next business day.
State due dates usually follow the same pattern, but not always. New York’s Form IT-2105 estimated payments for 2025 follow the same April 15, June 16, September 15, and January 15 schedule, so you’re fine there. Where it gets complicated is if you’re in a federally declared disaster area — the IRS has been issuing automatic postponements for taxpayers in certain states, and in recent years those have sometimes shifted quarterly deadlines by weeks or months. It’s worth checking the IRS disaster relief page around each deadline if your state has had recent FEMA declarations.
One practical thing we do for every client at The Reed Corporation is set up calendar reminders for all four federal and state estimated payment dates at the start of each year, adjusted for any weekend or holiday shifts. It sounds simple, but missing June 16 because you thought it was June 15 is the kind of thing that’s completely avoidable with a little upfront organization.
