What Are Quarterly Estimated Taxes—and Who Must Pay?
Quarterly estimated taxes are IRS payments that business owners, freelancers, gig workers, landlords, and others with untaxed income must pay throughout the year. Generally, you must pay if you expect to owe at least $1,000 in federal tax after subtracting withholding and credits from W-2 or other sources.
- Self-employed (sole proprietors/LLC/1099), S-corp shareholders, partners
- Anyone with significant investment, rental, or other non-withheld income

How Much to Pay Each Quarter
Free Tax Write-Off FinderEstimate your total annual tax: net self-employment income × 15.3% (for self-employment tax) + income tax, minus credits. Use the IRS 1040-ES worksheet. Divide the annual total into four equal payments—unless your income varies greatly by quarter, then use the annualized method (Form 2210).
Example:
- Net SE income: $80,000
- SE Tax = $80,000 × 92.35% × 15.3% = ~$11,304
- Subtract half SE tax ($5,652) from AGI, apply standard deduction
- Estimate income tax + SE tax ≈ $19,504/yr
- Quarterly payment ≈ $4,876

Safe Harbor Rules and Penalty Avoidance
Use the IRS safe harbor to avoid underpayment penalties. For 2026, avoid penalties by paying either:
- 90% of your actual 2026 tax (if income is down and predictable)
- 100% of your 2025 total tax (or 110% if 2025 AGI was over $150,000)
Split your safe harbor total evenly across all four deadlines. Even if you underpay in 2026, you’ll owe only the difference in April 2027—no penalty or interest if following safe harbor! Learn more at IRS Pub 505 or our MERNA™ Method page.
How to Make Estimated Tax Payments (IRS Methods)
- IRS Direct Pay: Online with checking/savings—immediate confirmation. IRS Direct Pay
- EFTPS (Electronic Federal Tax Payment System): Pre-schedule all quarterly payments at eftps.gov. Great for automation and record-keeping.
- IRS2Go App: On your phone.
- Mail check & voucher (Form 1040-ES), or pay by debit/credit (fees apply—not recommended).
See more payment details on our tax prep page or the IRS Payments portal.
Penalties for Missing a Quarterly Payment
Missed or underpaid payments trigger an IRS penalty (about 7% yearly as of 2026) on the unpaid amount, calculated from each deadline to when you catch up. Use IRS Form 2210 to annualize if your income is uneven. Waivers are possible for emergencies/disaster/illness.
Best Strategies by Self-Employed Persona
- Freelancers: Use prior-year safe harbor.
- Gig workers: Set aside 25–30% of every payment; track deductions (vehicle, home office, supplies).
- Variable income: Use annualized method for low quarters (Form 2210).
- High earners (>$150k): Pay 110% of prior year; consider S-corp status to reduce SE tax (LLC vs S-Corp Calculator).
Frequently Asked Questions
Are quarterly estimated taxes due on the same dates every year?
No, dates shift if the 15th falls on a weekend or holiday. Always check the IRS Tax Calendar for the current year.
Can I skip Q4 if I file early?
Yes. File early (by Feb 2, 2027 for 2026 tax year), pay what you owe, and the Q4 payment isn’t required.
Do these rules also apply to state taxes?
Most states do require estimated payments but deadlines, methods, and safe harbor rules vary. Check with your state’s tax department.
What if I have W-2 and 1099 income?
Increase employer withholding via Form W-4 to offset some or all of your 1099-side tax. Withholding is treated as if paid evenly year-round—even if withheld as a lump sum late in the year.
What if income varies a lot?
Use the annualized income method so you pay more in high-income quarters and less in slow ones—see Form 2210 instructions or contact our advisory team.
Can the IRS penalty be waived?
Yes, for disasters, major health events, or retirement. File Form 2210 and check for exceptions. See full details at IRS Form 2210.
