Frequently Asked Questions

When are quarterly taxes due?

For self-employed: April 15, June 15, September 15, January 15 (of the following year). If the 15th falls on a weekend or holiday, the deadline moves to the next business day.

How do I calculate quarterly payments?

Estimate annual net earnings × (Self-employment tax rate 15.3% + your expected income tax bracket). Divide by 4. Use Form 1040-ES to calculate. Pay through IRS Direct Pay or EFTPS. Don't underpay — penalties accrue on underpayment.

What if I can't pay quarterly taxes?

File the return anyway to avoid late filing penalties. Pay as much as you can. The IRS offers installment agreements. Underpayment penalties are based on how much you owe vs how much you should have paid.
