Missed Q1 Taxes? Here's How to Catch Up Before Q2

Missed the April 15 Q1 estimated tax deadline? You're not alone — April gets all the attention, and Q1 slips. The good news: Q2 is still 23 days away (June 16), and there's a clean path to catch up without filing a formal extension or talking to a CPA. Here's the exact playbook.

1. How Bad Is Missing Q1, Really?

It's fixable. The IRS doesn't send a squad to your house the day after a missed quarterly payment. The consequence is an underpayment penalty — essentially interest on the unpaid amount — which is calculated and assessed when you file your 2026 return in early 2027.

The penalty is roughly 8% annualized on the shortfall. If you owed $800 for Q1 and pay it in June, the penalty runs about $14 (8% annualized for ~2 months on $800). Not catastrophic.

It compounds if you miss Q2 too. If you also miss Q2, the penalty runs from April 15 through whenever you pay — and the shortfall grows. Q1 alone is minor. Q1 + Q2 + Q3 missed is a much larger bill.

The real risk is not catching up before Q2 ends. The penalty grows each quarter you don't pay. A driver who misses Q1, Q2, and Q3 will face a meaningful penalty bill when they file. But catching up at Q2 stops the bleeding.

2. Option 1: Combine Q1 + Q2 into One Payment (Recommended)

The cleanest fix is to pay both Q1 and Q2 estimated taxes together by June 16. The IRS has no rule against making a combined payment — and there's no penalty for paying two quarters at once, as long as you pay the total amount both quarters require.

1

Calculate your Q1 payment amount — what you should have paid by April 15. This is your annual estimated tax divided by 4. Use the QuarterPilot calculator to get your annual estimate, then divide by 4.

2

Calculate your Q2 payment amount — same method: annual estimated tax divided by 4.

3

Add them together — Q1 amount + Q2 amount = your combined June 16 payment.

4

Make the payment at irs.gov/payments — select "Estimated Tax" and include both Q1 and Q2 in the same transaction. Keep your confirmation receipt. The IRS will credit the payment to both quarters.

5

Resume normal quarterly schedule at Q3 — September 15 deadline, pay 1/4 of your annual estimate.

This approach requires you to come up with two quarters' worth of money by June 16. If that's not feasible, go to Option 2.

3. Option 2: Pay What You Can, Settle the Penalty at Filing

If you can't afford a double payment, pay as much as you can by June 16. The underpayment penalty is calculated on Form 2210 when you file your 2026 return — it's not an automatic disaster.

Here's how the penalty math works:

SituationPenalty Impact
Paid 0% of Q1, pay 100% of Q2 by June 16Small penalty on Q1 shortfall (runs ~2 months); resolves at filing
Paid 50% of Q1, pay 100% of Q2 by June 16Smaller penalty on the remaining 50% of Q1
Paid 0% of Q1, paid 0% of Q2 by June 16Larger penalty running longer; more to pay at filing
Pay nothing and wait until filingMaximum penalty; largest bill at filing time

The IRS always calculates the penalty in your favor when you make a catch-up payment. Any payment reduces the penalty proportionally. Paying something is always better than paying nothing.

4. The Safe Harbor Rule: Maybe No Penalty at All

There's a legal escape hatch for the underpayment penalty: the safe harbor rule. If you qualify, the IRS cannot charge a penalty even if you underpaid all year.

You qualify for safe harbor if either:

If you had very low or zero tax in 2025 (you were a new driver, part-time, or had a W-2 job covering most of your tax liability), the IRS penalty for Q1 underpayment is $0. The penalty requires you to have had a meaningful tax obligation last year. A driver who started in late 2025 has essentially no 2025 tax — no penalty possible in 2026.

The safe harbor rule is why many gig drivers who missed Q1 still get no penalty. If last year's total tax was low, the underpayment calculation produces zero penalty.

5. Calculate Your Catch-Up Amount in 60 Seconds

Don't guess. Use the QuarterPilot state calculator to get your exact annual estimate, then divide by 4 for each quarter's amount. Your catch-up payment is Q1 amount + Q2 amount.

Example: A California DoorDash driver earning $35,000/year gross has an estimated annual tax of ~$4,200. Each quarterly payment = $1,050. If they missed Q1, they owe $1,050 (Q1) + $1,050 (Q2) = $2,100 by June 16. Use the free calculator to get your specific number.

For high-income states like California and New York, the catch-up amount can be significant. A driver earning $60,000/year in California may owe $1,500–$2,000 per quarter — making the combined Q1 + Q2 payment $3,000–$4,000. This is uncomfortable but far better than letting the penalty compound across three missed quarters.

6. Don't Forget State Q1 Estimated Taxes

If you live in a state with income tax, you also need to make state estimated tax payments — and you may have missed those too. State underpayment penalties vary by state:

The state catch-up mirrors the federal approach: pay the missed quarter(s) with your next quarterly payment, or settle the state penalty at your state tax filing. Check your state's revenue department website for the specific payment portal and catch-up instructions.

Once you catch up, set up a system so Q3 doesn't also become a crisis:

Frequently Asked Questions

Can I pay Q1 and Q2 estimated taxes together on the IRS website?

Yes. Go to irs.gov/payments, select "Estimated Tax," and make one payment for the combined total. In the payment description or memo, note "Q1 + Q2 estimated tax." The IRS will split it across quarters based on your designation. Keep the confirmation number.

What if I can't afford to pay both Q1 and Q2 by June 16?

Pay as much as you can. Any payment reduces the underpayment penalty proportionally. There's no minimum required catch-up payment — but the penalty accrues until you pay. The IRS also offers an installment agreement if you can't pay the full amount by the Q2 deadline.

Will the IRS charge a penalty for missing just Q1 but paying Q2 on time?

Yes, but it's small. The Q1 underpayment penalty runs from April 15 to the date you pay (or to the date you file, whichever comes first). If you pay Q1 + Q2 together in June, the penalty on Q1 is roughly 2 months of underpayment interest on the Q1 amount. For most gig drivers, that's $10–$40. Not catastrophic.

Is there a way to avoid the penalty even if I underpaid Q1?

Yes — the safe harbor rule. If your 2025 tax liability was under $1,000 (or you paid 100% of it in quarterly installments), the penalty cannot be assessed for 2026. Most gig drivers who started in 2024-2025 have low enough prior-year tax to qualify automatically. The IRS calculates this on Form 2210 at filing.

Should I file an extension if I missed Q1?

No. The annual filing extension (Form 4868) extends your return deadline to October 15 — it does not extend quarterly estimated tax deadlines. Missing Q1 is not fixed by filing an extension; it's fixed by making the payment. An extension only helps if you can't file your annual return by April 2027.

Do I need to notify the IRS that I'm catching up on Q1?

No. There's no notification required for a missed quarterly payment. You simply make the payment (Q1 + Q2 together) and keep your confirmation. The IRS reconciles underpayments when you file your Form 1040 for the year. If you're using a tax preparer, tell them you missed Q1 so they can fill out Form 2210 correctly.
