Quarterly Estimated Taxes: Dates Every Small Business Owner Should Know

Owners who do not have taxes withheld from their income, such as sole proprietors, partners, and many LLC and S-Corp owners, usually pay estimated taxes during the year instead of all at once in April.

The federal due dates are generally April 15, June 15, September 15, and January 15 of the following year. When a date falls on a weekend or holiday, it moves to the next business day. Your state may have its own schedule.

Missing or underpaying a quarter can lead to penalties and interest. A quick mid-year check of your income and expenses helps you set each payment at a realistic amount, rather than guessing.
