Quarterly Estimated Tax Reminder: Avoid IRS Penalties Every Year

According to the IRS, underpayment penalties affected millions of taxpayers in recent years, with average penalties of $150–$500 for a single missed quarter. For high earners and consistent freelancers, a missed quarter can cost far more. The penalty isn't a flat fine — it's an interest charge that accrues from the day the payment was due.

The Four Quarterly Estimated Tax Deadlines

These dates don't move much year to year. Mark them permanently:

Important: When April 15 falls on a weekend or holiday (which happens in some years), the deadline moves to the next business day. The June 15 and September 15 deadlines follow the same rule.

Notice that Q2 only covers April–May (2 months), not a full quarter. Many freelancers miss this because it feels counterintuitive — the June payment covers less income than the other quarters.

Who Must Pay Quarterly Estimated Taxes

You must pay quarterly estimated taxes if you expect to owe at least $1,000 in federal tax after subtracting withholding and credits. This includes:

• Freelancers and contractors receiving 1099-NEC income
• Self-employed business owners (sole proprietors, LLCs taxed as sole proprietors)
• Gig workers (Uber, Lyft, DoorDash, Airbnb hosts, Etsy sellers)
• Investors with significant capital gains or dividend income
• Real estate investors with rental income
• Anyone with a W-2 job who has significant additional income from freelancing, consulting, or investments

If you're on a W-2 salary with no other income, your employer withholds throughout the year and you don't need quarterly estimated payments (unless your withholding is insufficient).

How to Calculate Your Quarterly Payment

The Safe Harbor Method (Simplest, No-Penalty Guarantee)

Pay 100% of your prior-year tax liability divided by 4. If your prior-year AGI was over $150,000, pay 110% of your prior-year liability divided by 4.

Example: Last year you paid $12,000 in federal taxes. Your quarterly safe harbor payment is $12,000 ÷ 4 = $3,000 per quarter. Pay that amount each quarter and you avoid underpayment penalties even if you owe more at filing.

Find your prior-year tax liability on Form 1040, Line 24 (Total Tax).

The Current-Year Estimate Method (More Accurate, Lower Payments)

Estimate your current-year income, subtract business deductions and the QBI deduction (20% of qualified business income for eligible self-employed), calculate your projected income tax plus self-employment tax, then divide by 4.

This method requires more calculation but avoids overpaying significantly. Many freelancers use accounting software (QuickBooks, FreshBooks, Wave) to track income and generate estimated quarterly tax calculations automatically.

Setting Up Quarterly Estimated Tax Reminders

The most reliable approach: set reminders for both the preparation date (2 weeks before) and the due date.

Setting All Four Deadlines in YouGot

YouGot makes this straightforward — enter each reminder once in plain language:

Remind me every April 1 that my Q1 estimated federal tax payment is due April 15 — calculate based on Q1 income and pay via IRS Direct Pay. Remind me every June 1 that my Q2 estimated tax payment is due June 15 — Q2 covers only April-May income, not the full quarter. Remind me every September 1 that my Q3 estimated tax payment is due September 15 — calculate based on June-August income. Remind me every January 1 that my Q4 estimated tax payment is due January 15 — final quarterly payment for September-December income.

Also set due-date reminders as a backup:

Remind me every April 15 to confirm my Q1 estimated tax payment was submitted successfully to IRS Direct Pay before 8pm ET today.

Freelancers and self-employed workers can explore YouGot's freelancer landing page for more tools designed around irregular income schedules.

Try These Quarterly Tax Reminders

Remind me every April 1 to calculate my Q1 freelance income and pay my quarterly estimated taxes via IRS Direct Pay before April 15. Text me every June 1 that Q2 estimated taxes are due June 15 — this quarter only covers April and May, not three full months. Remind me every September 1 to run my Q3 income summary in QuickBooks and submit my estimated tax payment before September 15. Alert me every January 1 that my Q4 estimated tax payment is due January 15 and I should also gather documents for the upcoming tax filing season. Remind me every March 15 to schedule a meeting with my accountant to review Q1 estimated payments and plan for the rest of the tax year.

State Quarterly Estimated Taxes: Don't Forget These

Most freelancers remember federal estimated taxes but forget that most states with income tax also require quarterly estimated payments on the same schedule. California, New York, and most other states with income tax impose similar underpayment penalties.

Check your state's tax agency website for state-specific quarterly due dates — they often match the federal schedule but some states have slightly different dates.

Remind me every April 1 to pay both federal (IRS) and California FTB estimated taxes before their respective April 15 deadlines.

IRS Direct Pay: The Simplest Payment Method

For one-time or quarterly payments, IRS Direct Pay (irs.gov/payments) is free, fast, and posts same-day if submitted before 8pm ET. No account setup required — just your bank routing and account numbers, your prior year AGI for identity verification, and the payment amount and tax period.

Alternatively, EFTPS (Electronic Federal Tax Payment System) requires a one-time setup but allows you to schedule future quarterly payments in advance — useful if you want to automate the payment itself, not just the reminder.

See YouGot's pricing — the free tier is sufficient for four annual recurring reminders.

Frequently Asked Questions

When are quarterly estimated taxes due?

April 15 (Q1), June 15 (Q2), September 15 (Q3), January 15 of the following year (Q4). When a deadline falls on a weekend or federal holiday, it shifts to the next business day. Note that Q2 covers only April–May income (2 months), not a full quarter.

Who needs to pay quarterly estimated taxes?

Anyone who expects to owe at least $1,000 in federal tax after subtracting withholding and credits. This includes freelancers, contractors, gig workers, self-employed business owners, and anyone with significant investment, rental, or side income not subject to withholding.

How do I calculate my quarterly estimated tax payment?

The safest method: pay 100% of your prior-year tax liability divided by 4 (110% if your prior AGI exceeded $150,000). This 'safe harbor' method guarantees no underpayment penalties even if you owe more at filing. Find your prior-year tax liability on Form 1040, Line 24.

What happens if I miss a quarterly estimated tax payment?

The IRS charges an underpayment penalty — currently around 7–8% annually — on the amount underpaid for each quarter. The penalty accrues from the missed due date, so paying everything at filing doesn't eliminate the per-quarter penalty charges.

Can I pay estimated taxes online?

Yes — IRS Direct Pay at irs.gov/payments is free, posts same-day (before 8pm ET), and requires no account setup. EFTPS allows advance scheduling. Credit and debit card payments are accepted through IRS-authorized third parties but charge a processing fee of 1.82–1.98%.
