Quarterly Estimated Tax Reminder: Never Miss an IRS Deadline Again

A quarterly estimated tax reminder is the single most valuable financial reminder a self-employed person can set. Miss a deadline by even one day and the IRS automatically calculates an underpayment penalty on your annual return — no warning, no bill, just a surprise charge when you file. Setting four dated reminders takes under two minutes and can save you hundreds of dollars a year.

The Four Deadlines You Must Remember Every Year

The IRS sets four quarterly estimated tax due dates each year:

Quarter	Period Covered	Due Date
Q1	January 1 – March 31	April 15
Q2	April 1 – May 31	June 15
Q3	June 1 – August 31	September 15
Q4	September 1 – December 31	January 15 (next year)

Note the Q2 deadline: April 1 through May 31 — just two months. The Q4 deadline falls in January of the following year. These dates shift when they fall on weekends or federal holidays.

"The IRS doesn't send you a reminder. The penalty isn't a courtesy notice — it's a line item on your tax return that appears silently, months after you should have paid."

Who owes quarterly estimated taxes:

• Freelancers and independent contractors
• Self-employed business owners (sole props, single-member LLCs)
• Partners in a partnership
• S-corp shareholders receiving distributions
• Anyone with $1,000+ in expected tax liability not covered by withholding
• Investors with significant capital gains, dividends, or rental income

Set Quarterly Estimated Tax Reminders in 5 Minutes

The cleanest solution: set four repeating annual reminders, each tied to its deadline date. YouGot accepts these in plain language:

Setting the reminder one day before gives you time to log in and process the payment without risking a same-day banking delay counting against you.

How Much to Pay Each Quarter

The IRS offers a penalty-free safe harbor if you pay at least:

• 100% of last year's total tax (in four equal installments), or
• 90% of your current year's actual tax, or
• 110% of last year's tax if your prior-year AGI exceeded $150,000

Most freelancers use the simplest method: take last year's total federal income tax (line 24 on Form 1040) and divide by four. That's your quarterly payment. Pay that amount four times and you owe no penalty regardless of what you earn this year.

For state taxes, check your state's estimated tax rules — most follow a similar quarterly schedule but with different forms and portals.

The Cost of Forgetting

The IRS underpayment penalty rate has been running around 8% annualized on unpaid balances. On a $5,000 quarterly underpayment:

• One month late: ~$33 penalty
• Full quarter late: ~$100 penalty
• Entire year underpaid: ~$400+ in cumulative penalties

That's real money for a two-minute setup. See yougot.ai/#pricing — the free tier includes recurring annual reminders.

Frequently Asked Questions

When are quarterly estimated taxes due?

For most years: April 15 (Q1), June 15 (Q2), September 15 (Q3), and January 15 the following year (Q4). Deadlines shift when they fall on weekends or federal holidays. Self-employed people, freelancers, and anyone with $1,000+ in expected non-withheld tax liability generally must pay quarterly.

What happens if you miss a quarterly estimated tax deadline?

The IRS charges an underpayment penalty — currently ~8% annualized on the shortfall — automatically applied when you file your annual return. No advance warning arrives; the penalty appears on your Form 1040 when filed. Paying late before the next quarter reduces but doesn't eliminate the penalty.

How much should I pay for quarterly estimated taxes?

The safe harbor: pay 100% of last year's total tax (110% if prior-year AGI exceeded $150,000) divided into four equal payments, or 90% of current year's actual liability. Most freelancers divide last year's Form 1040 line 24 tax by four for a simple, penalty-safe quarterly amount.

Yes — YouGot lets you set four annual reminders with exact dates in plain language. Type 'remind me every April 14 to pay Q1 estimated taxes at irs.gov/payments' and it fires annually. Set reminders one day early to give yourself payment processing time.
