Quarterly Tax Deadlines 2026 — Every Date You Need

If you're self-employed or get a 1099, these are the four dates you need to remember. Miss one and you'll owe interest and potentially penalties.

The 2026 Quarterly Dates

| Quarter | Income Period | Due Date | Day of Week | |---|---|---|---| | Q1 | January 1 – March 31 | April 15, 2026 | Wednesday | | Q2 | April 1 – June 30 | June 15, 2026 | Monday | | Q3 | July 1 – September 30 | September 15, 2026 | Tuesday | | Q4 | October 1 – December 31 | January 15, 2027 | Friday |

None of the 2026 deadlines fall on a weekend, so there are no automatic extensions. Mark all four dates on your calendar now. Set a reminder for 5 days before each due date.

How to Make a Payment

The IRS offers several payment methods:

IRS Direct Pay (Recommended)

- Free, instant confirmation, no fees - Requires bank account information - Navigate to irs.gov/payments and click "Direct Pay" - Takes 5 minutes, get confirmation number immediately - You can schedule payments up to 120 days in advance

Credit or Debit Card

- Through third-party processors (IRS.gov lists approved vendors) - 3% convenience fee (so $3,000 payment costs $90 extra) - Instant confirmation - Use only if you need to charge to a card and want the rewards points

Electronic Federal Tax Payment System (EFTPS)

- Free, automated, recurring payments available - Requires enrollment (takes 1–2 weeks) - Can set up automatic quarterly payments - Best if you want "set it and forget it"

Check by Mail

- Mail to your local IRS office with Form 1040-ES - Include your name, address, SSN, tax year, and amount - Takes 2 weeks to process; don't mail on due date - Get certified mail receipt; keep for records - High risk if lost in mail — track with postal confirmation

Pro tip: Use IRS Direct Pay on your phone the night before each deadline. It's instant and you get a confirmation number that proves payment was on time.

What Happens If You're Late

The IRS charges 8% annual interest on unpaid quarterly taxes, calculated from the due date of each quarter. For Q1 2026 (due April 15), if you don't pay until June 15, you owe 8% annual interest for 2 months (roughly 1.3%).

Example: $3,000 Q1 payment due April 15, paid June 15 = $40 in interest owed.

If you're more than 90 days late, you may also owe a penalty (typically 0.5% per month of unpaid tax, up to 25%). Combined with interest, a 6-month-late payment costs roughly $250 on a $3,000 bill.

Bottom line: It's cheaper to pay on time than to pay late. If you can't pay in full by the due date, pay what you can — partial payments reduce interest accrual compared to zero payment.

Who Has to Make Quarterly Payments

You owe quarterly estimated taxes if:

- You're self-employed (freelancer, contractor, sole proprietor) and expect to owe more than $1,000 in total federal tax for 2026 - You receive a 1099-NEC or 1099-MISC and expect to owe more than $1,000 - You have short-term rental income without enough withholding - You have S-Corp distributions and don't have enough payroll withholding - You have other income (capital gains, dividends) without sufficient withholding

You do NOT owe quarterly payments if: - All your income is from W-2 employment with correct withholding - You're retired and living on Social Security / pension - You're a full-time employee with no side income

Safe Harbor — No Penalty Guarantee

If you pay 100% of last year's federal tax (or 110% if you earned over $150,000), you avoid all penalties even if your actual 2026 tax bill is higher. You still owe interest on the shortfall, but not penalty.

Example: You owed $8,000 federal tax in 2025. Pay $2,000 each quarter in 2026 (total $8,000). Your 2026 actual tax turns out to be $12,000. You owe 8% interest on the $4,000 shortfall (~$160), but zero penalty.

This is your safety net — use it if you're unsure of your actual tax liability.

Adjusting Your Payments Mid-Year

If your income drops (lost a client, slow season), you can lower your Q3 or Q4 payment. Recalculate your annual income estimate and adjust. Form 1040-ES provides a worksheet to do this.

If your income surges (new client, bonus), increase your payment to avoid a huge balance-due when you file. You can make an extra payment any time before filing — the IRS doesn't limit payment frequency.
