Häufig Gestellte Fragen
When are quarterly taxes due?
Q1: April 15, Q2: June 15, Q3: September 15, Q4: January 15 of the following year. If a due date falls on a weekend or holiday, it moves to the next business day.
What happens if I underpay?
The IRS charges an underpayment penalty (currently ~8% annual rate). To avoid penalties, pay at least 90% of current year tax or 100% of prior year tax (110% if AGI > $150,000).
Can I pay through withholding instead?
Yes. If you have a spouse with W-2 income, you can increase their withholding to cover your self-employment tax, eliminating the need for quarterly payments.
