Question: How Do I Pay Estimated Taxes? When Must I Make Estimated Tax Payments?
Answer:

What Are the Requirements for Paying Estimated Taxes?
You will need to pay estimated taxes depending on how much you owe and your business legal type.

Non-Corporation
If you are a sole proprietor, partner, or s-corporation shareholder, you will need to pay estimated taxes if both of the following apply:

  • You expect to owe at least $1,000 in tax for this calendar year after subtracting your withholding and credits.
  • You expect your withholding and credits to be less than the smaller of:
    • 90% of the tax to be shown on your tax return, or
    • 100% of the tax shown on last year's income tax return. Your tax return for last year must cover all 12 months.

Corporation
If you are filing a tax return for a corporation, you generally have to make estimated tax payments for your corporation if you expect it to owe tax of $500 or more when you file its return.

When to Pay
Due dates for estimated taxes are based on when income was received:

  • For income received for the period January 1 through March 31, the due date is April 15.
  • For income received for the period April 1 through May 31, the due date is June 15.
  • For income received for the period June 1 through August 31, the due date is September 15.
  • For income received for the period September 1 through December 31, the due date is January 15 of the next year.

How Much to Pay
The IRS general rule is that you must pay the smaller of:

  • 90% of your total expected tax for this year, or
  • 100% of the total tax shown on your last year's return. Your last year tax return must cover all 12 months.
