Frequently Asked Questions
Common questions about quarterly tax payments
Who needs to make quarterly tax payments?
You generally need to make quarterly payments if you expect to owe $1,000 or more in taxes when you file your return and your withholding and refundable credits are less than 90% of the current year's tax or 100% of last year's tax (110% if your prior year AGI exceeded $150,000).
What happens if I don't make quarterly payments?
If you don't make required quarterly payments, you may be subject to underpayment penalties. The penalty is calculated based on the amount you underpaid and how long the payment was overdue. The current underpayment penalty rate is updated quarterly by the IRS.
Can I adjust my quarterly payments during the year?
Yes, you can adjust your quarterly payments if your income changes during the year. You can use the annualized income installment method if your income is uneven throughout the year, which may allow for smaller payments in earlier quarters.
What's the safe harbor rule?
The safe harbor rule protects you from underpayment penalties if you pay either 90% of the current year's tax or 100% of last year's tax (110% if your prior year AGI exceeded $150,000). Meeting either threshold ensures you won't face penalties, even if you owe additional tax when filing.
How do I make quarterly tax payments?
You can make quarterly payments online through the IRS Direct Pay system, by phone, by mail with Form 1040ES, or through the Electronic Federal Tax Payment System (EFTPS). Online payments are typically processed faster and provide immediate confirmation.
What if I miss a quarterly payment deadline?
If you miss a quarterly payment deadline, make the payment as soon as possible to minimize penalties. You can't make up for a missed quarterly payment by paying more in the next quarter - each quarter is calculated separately for penalty purposes.
