A quarterly estimated tax reminder texts you before each IRS payment is due so you have time to calculate what you owe, transfer funds, and make the payment — not search for the due date at 11pm on April 15th. The IRS underpayment penalty runs approximately 7–8% annualized (adjusted quarterly). For a $2,000 missed payment, that's $140–$160 per year in avoidable penalties, plus the stress of the underpayment notice.

YouGot delivers recurring reminders via SMS. Set your four quarterly tax reminders once and receive a text 10 days before each due date, every year.

Who Needs Quarterly Estimated Tax Reminders

If you had income without withholding in the current tax year, you likely need to pay estimated taxes. This includes:

Freelancers and independent contractors (1099 income)
Self-employed business owners (sole proprietors, single-member LLCs)
Gig economy workers (Uber, DoorDash, Etsy, Airbnb, etc.)
Investors with significant capital gains or dividend income
Employees with substantial side income above their withholding

The IRS requires you to pay estimated taxes if you expect to owe at least $1,000 when you file and your withholding and credits cover less than 90% of your current-year tax or 100% of last year's tax (the "safe harbor" rule).

The 2025 Quarterly Estimated Tax Due Dates

The IRS uses a slightly irregular "quarterly" schedule — not evenly spaced:

Payment Period	Due Date
Jan 1 – Mar 31 (Q1)	April 15, 2025
Apr 1 – May 31 (Q2)	June 16, 2025
Jun 1 – Aug 31 (Q3)	September 15, 2025
Sep 1 – Dec 31 (Q4)	January 15, 2026

Note: When the due date falls on a weekend or federal holiday, it shifts to the next business day.

Set reminders for 10 days before each due date so you have buffer time for calculation and fund transfers.

Setting Up Quarterly Tax Reminders in YouGot

Step 1: Set All Four Reminders Now

Open YouGot and set four reminders for the current and next tax year. Type each one separately:

YouGot schedules annual reminders at specific dates. Set them once and they fire every year automatically.

Step 2: Add a "Calculate Your Estimate" Pre-Reminder

The week before the payment is due, you need to calculate what you owe. Set a second round of reminders 14 days before each due date:

Step 3: State Estimated Tax Reminders

If your state has an income tax (most do), state estimated tax due dates often mirror federal dates but not always. California, for example, has different Q1 and Q2 dates. Set state reminders separately:

Each of these fires as an SMS on the specified date each year. No calendar management, no annual re-setting — you configure it once.

How Much to Pay: The Safe Harbor Method

Calculating estimated taxes can be complex. The safe harbor method simplifies it:

Safe Harbor Rule: Pay at least 100% of last year's total tax liability (110% if your AGI was over $150,000) spread across four quarterly payments, and you'll owe no underpayment penalty regardless of what you actually earn this year.

Example: You paid $8,000 in federal income tax last year. Divide by 4 = $2,000 per quarter. Pay $2,000 each quarter and you're safe from underpayment penalties, even if you earn significantly more this year.

This method trades potential overpayment (you'll get a refund at filing) for certainty (no underpayment penalty). For freelancers with variable income, certainty has real value.

Key stat: According to IRS data, more than 10 million Americans paid an underpayment penalty in recent years — the majority of them self-employed. The median penalty was approximately $140. It's avoidable with a calendar reminder.

What Happens If You Miss a Quarterly Payment

Missing a quarterly estimated tax payment doesn't result in immediate IRS contact. The penalty is calculated at filing time:

Underpayment penalty rate: Approximately 7–8% annualized (the federal short-term rate plus 3 percentage points, adjusted quarterly).
How it's calculated: The IRS charges interest on the underpaid amount from the due date through the date you actually pay.
When you discover it: Usually when you file your return and see a higher-than-expected tax bill.

The penalty itself is often modest — a few hundred dollars — but it's completely avoidable with a reminder that takes 30 seconds to set.

Frequently Asked Questions

When are quarterly estimated taxes due in 2025?

The 2025 IRS estimated tax due dates are: April 15 (Q1), June 16 (Q2), September 15 (Q3), and January 15, 2026 (Q4). Set reminders 10 days before each date for time to calculate and transfer funds. Use YouGot to set annual SMS reminders that fire automatically every year.

What happens if I miss a quarterly estimated tax payment?

Missing a quarterly estimated tax payment triggers an underpayment penalty, calculated at approximately 7–8% annualized on the amount not paid. The penalty is assessed at tax filing time. It's avoidable by paying at least 100% of last year's tax liability across four equal quarterly payments (the safe harbor method).

Do I have to pay quarterly estimated taxes if I'm self-employed?

Generally yes, if you expect to owe at least $1,000 in federal income tax and your withholding won't cover 90% of your current-year tax (or 100% of last year's tax). Most freelancers and self-employed individuals with meaningful income need to pay quarterly. Consult a tax professional if you're uncertain.

Can I set a quarterly reminder that fires every year automatically?

Yes. YouGot supports annual recurring reminders. Set "Remind me on April 5 every year to pay my Q1 estimated taxes" once and it fires automatically each year. Sign up at yougot.ai.

What's the easiest way to calculate quarterly estimated taxes?

The simplest method: take last year's total federal tax bill, divide by four, and pay that amount each quarter. This is the safe harbor method — it eliminates underpayment penalties even if you earn more this year. For a more accurate estimate, use IRS Form 1040-ES or your tax software's estimated tax calculator.
