For U.S. citizens who do not have taxes automatically withheld from their income, the IRS requires that they make quarterly tax payments directly to the IRS. For those interested, we do offer income tax liability estimates to educate and empower you to properly make those quarterly payments. To prepare your estimate, we will need the appropriate data which can be found on our Tax Estimation Checklist. Our rate is the same as our hourly rate for preparing your tax return.​

​

Quarterly Tax Payments Due Dates*:

• ​April 15th (1st Quarter)

• June 15th (2nd Quarter)

• September 15th (3rd Quarter)

• January 15th (4th Quarter)

*Generally, the IRS only enforces that all tax payments be made by January 15th. Owing after that could result in late penalties.

You can make tax payments to the IRS on their website here. If you prefer to pay by mail, you can print off vouchers for your payments by printing this form. The vouchers can be found on pages 10 & 11. Page 9 has a log where you can record your payments. If you haven't already paid us to estimate your tax liability for you, page 8 has a worksheet for you to estimate your taxable income for the year, and page 7 contains a tax rate schedule for computing your estimated tax. Finally, page 5 has a table for you to use to find where to properly mail your check and your Form 1040-ES Payment Voucher.​
