FAQQuarterly Estimated Taxes questions
When are quarterly estimated taxes due?
Usually April 15, June 15, September 15 and January 15 of the next year. When a date falls on a weekend or holiday, it moves to the next business day.
Who needs to pay estimated taxes?
Generally, anyone who expects to owe $1,000 or more in federal tax for the year after withholding, which includes most self-employed people and business owners.
How do I avoid an underpayment penalty?
In general, you avoid it if you pay at least 90% of this year's tax or 100% of last year's tax (110% if your adjusted gross income was over $150,000) through withholding and estimates.
Is this an extra cost?
No. Quarterly estimate calculations are included in the Business Tax plan.
