Frequently Asked Questions
Who needs to pay estimated taxes?
You generally must pay estimated taxes if you expect to owe $1,000 or more in taxes after subtracting your withholding and refundable credits.
What is the safe harbor rule?
Safe harbor protects you from underpayment penalties. Pay either 100% of last year's tax (110% if AGI exceeds $150K) or 90% of this year's tax.
What happens if I miss a payment?
You may owe an underpayment penalty. It's better to make a late payment than skip entirely. The penalty is calculated on the amount and time period of underpayment.
How do I pay estimated taxes?
Pay online at IRS.gov/payments, mail Form 1040-ES with a check, or pay by phone. Electronic payments are fastest and provide immediate confirmation.
