Certain Washington state businesses qualify to have a reseller permit. The Department issues permits to businesses that regularly make purchases for resale or meet other specific criteria. It is free for any business to apply for a reseller permit.
If you don’t have a reseller permit but need to make purchases for resale without paying sales tax, you can pay retail sales tax on purchases and:

The “taxable amount for tax paid at source” deduction is based on the amount paid for the materials, not including the sales tax. It’s important to note that sales tax must be collected on the total price of the item or contract when the materials are resold. This sample question demonstrates how this works:

Q: I’m a custom contractor. I recently bought lumber and paid sales tax at the time of purchase. Later, I built a fence with that lumber and collected sales tax. Is there a way to get the sales tax I paid back from my purchase of that lumber?

A: Yes. In order to be paid back for the sales tax that you paid originally, you can take what is called a “taxable amount for tax paid at source” deduction on your return.

Example:

ABC Company purchased lumber for $100 from a Seattle store, plus sales tax of $9.50(rate of 9.5%).
State portion of sales tax: $6.50 ($100 x 6.5% or 0.065)
Local portion of sales tax: $3.00 ($100 x 3.0% or 0.030)

ABC was later hired to build a fence in Tacoma using the lumber purchased in Seattle. The total amount earned for the contract was $500, plus $46.50 in sales tax (rate of 9.3%).
State portion of sales tax: $32.50 ($500 x 6.5% or 0.065)
Local portion of sales tax: $14.00 ($500 x 2.8% or 0.028)

This is how the deduction would look on your Combined Excise Tax Return.
