How to File Sales Tax in Washington


How to Register: You can register your business online or by downloading a paper Business License Application and mailing it in.

Registration Cost: There is a $19.00 non-refundable application fee and $5.00 non-refundable fee for each Trade Name you register. Some of the licenses available on-line have additional fees.

Filing Requirements: Monthly and Quarterly taxpayers must file and pay their taxes electronically. For taxpayers who are not required to file and pay electronically pre-printed returns are mailed about four weeks before the due date.

Due Date: Monthly returns are due the 25th of every month. (e.g. The June tax return is due July 25.)

Quarterly returns are due the end of the month following the tax quarter. (e.g. The Quarter 1 (Jan, Feb, Mar) tax return is due April 30.)

Annual returns are due January 31.

Where to File: Department of Revenue-Washington State

What Will You Need: File your return electronically using E-file, the Department’s online filing tool. To use E-file, you must create an online account. You will need your Tax Registration/UBI Number and Pre-Assigned Access Code (PAC).

If filing via paper, your nine-digit Tax Registration Number is printed above your name and address on the tax return. Write this number on: the deduction detail pages (if reporting deductions on your tax return), any related forms, and your check.

Renewal: An expiration date is printed on the top right-hand corner of your Business License document. Business Licensing Service will send you a renewal notice approximately 45 days before your license expires.
