# Estimated tax payments
If you expect to owe tax on business income that has no withholding, you pay estimated tax during the year. For a sole proprietor, these payments cover your personal income tax and self-employment tax.
Due dates
For an individual, the usual due dates for calendar-year filers are April 15, June 15, September 15 and January 15 of the next year. If a date falls on a weekend or holiday, it moves to the next business day. Check Form 1040-ES on irs.gov for the current year. Corporations have their own schedule.
Recording a payment
- Pay from the business bank account, or record the payment when it leaves the bank.
- Use an equity account for owner draws rather than an expense account. Create one in the chart of accounts if you do not have it.
- Record the date, the amount and the bank account. Match it on the bank review once the bank import is in.
- Keep the payment confirmation from the IRS or your bank with your records.
Why it doesn't count as an expense
Estimated tax is a prepayment of your own income tax. It doesn't count as a cost of running the business. Recording it as an expense would understate profit and would change the tax-line totals. For a sole proprietor or partner, it is an owner draw.
For a C corporation, the payment is tax on the company's own income, and it is recorded differently. Ask your accountant which account to use.
Things to check
- Whether you owe a penalty for underpayment. This depends on safe harbour rules, so ask your accountant.
- The payments made in the year, against the amount on your return.
