A Washington reseller permit lets retailers, wholesalers, manufacturers, and certain contractors buy goods for resale without paying sales tax at the register. The Department of Revenue (DOR) issues the permit at no cost through its My DOR online portal, and a standard permit is good for four years. Using it on a purchase that doesn’t qualify triggers a penalty of 50% of the tax that should have been paid, plus the tax itself and interest, so getting both the application and the day-to-day use right matters.
Who Qualifies
The permit is for businesses that actually make purchases at wholesale: retailers buying inventory, wholesalers stocking goods for distribution, and manufacturers buying raw materials or components that become part of a finished product. The DOR looks at the nature of your business and your real purchasing patterns when deciding whether you qualify.
You need the appropriate Washington business licenses and endorsements before applying. Contractors also need a valid Labor and Industries contractor’s license. If your revenue comes primarily from services rather than the sale of tangible goods, expect closer scrutiny of whether your purchases genuinely qualify as wholesale.
The DOR must deny your application if your business isn’t entitled to make wholesale purchases, if the application contains a material misstatement, or if it’s incomplete. The department can also deny an application when doing so serves the interest of collecting taxes owed under the state’s revenue title. Outstanding tax liabilities, unfiled returns, and prior audit findings involving improper permit use all give the DOR reason to say no.
How to Apply
There is no fee to apply for or renew the permit. Applying online through My DOR is the fastest route:
- Log in at dor.wa.gov and open your excise tax account.
- Click the “Apply for/view a Reseller Permit” link.
- Complete the fields covering your business structure, industry classification, and anticipated resale activities.
Paper applications are accepted but take longer. You’ll need a valid Uniform Business Identifier (UBI) tying your business to its state tax records. If you operate under a trade name, include a copy of your trade name registration.
Beyond the basics, the DOR wants evidence that you actually buy goods for resale. Established businesses can point to past excise tax filings showing retail sales and sales tax collected. New businesses without that history should be ready to supply business plans, lease agreements, supplier letters of intent, invoices, or purchase orders. The department may also ask for ownership details and personal identification to screen out fraudulent applications.
The DOR is required to use its best efforts to decide a complete application within 60 days. If it doesn’t rule inside that window, you can request a formal review or resubmit. Incomplete or inconsistent information is the most common cause of delay, so check everything before you send it. Once approved, the permit is issued electronically and lives in your My DOR account, and you present it to suppliers when making tax-exempt purchases.
How Long the Permit Lasts and How to Renew
A standard reseller permit is valid for 48 months from the date it’s issued, renewed, or reinstated. The DOR shortens that to 24 months if any of the following apply:
- You’re a contractor.
- Your business has been registered less than one year on the date the DOR received your application.
- You reported no gross income in the 12 months before applying.
- You were on nonreporting status when the DOR received your application.
- You failed to file tax returns covering any part of the 12 months before the DOR received your application.
A 24-month permit can be renewed for the standard 48-month period once you’ve cleared whatever condition triggered the shorter term.
Renewal is not automatic. You reapply through My DOR and show continued eligibility, meaning you’re still making wholesale purchases and current on your tax obligations. The DOR sends renewal notices before the permit expires, but changed operations, missed filings, or unpaid tax will pull your application into additional review. If renewal is denied, you lose the ability to make tax-exempt purchases until the underlying issues are resolved.
Using the Permit Correctly
The permit only covers purchases of items and services you’ll resell. Buying something tax-free with your permit and then keeping it for your own business use is where most trouble starts.
Use Tax on Items You Don’t Resell
If you buy something tax-free using the permit and then use it in your own operations instead of reselling it, you owe use tax on that item. Washington’s use tax applies whenever you consume tangible personal property or certain services that weren’t subject to retail sales tax at purchase, and the use tax rate matches the sales tax rate that would have applied.
This comes up often with mixed inventory. A restaurant supply company might purchase commercial equipment intending to resell it, then decide to keep a piece for its own warehouse. That equipment now triggers a use tax obligation, which the business must self-report and remit on its excise tax return. Skipping that step is exactly the kind of improper use that draws penalties in an audit.
Drop Shipments and Out-of-State Buyers
Drop shipments involve two sales: a wholesale sale from the manufacturer to the retailer, and a retail sale from the retailer to the customer. The manufacturer doesn’t collect retail sales tax on the shipment but must document the wholesale nature of the sale. It needs one of three documents from the retailer: a Washington reseller permit, a Streamlined Sales Tax (SST) exemption certificate, or a Multistate Tax Commission (MTC) exemption certificate. Without one of those, the manufacturer has to collect and remit sales tax.
Washington belongs to the Streamlined Sales and Use Tax Agreement and accepts the MTC’s uniform multijurisdiction resale certificate. Buyers not required to register in Washington can use those certificates in place of a Washington-issued reseller permit.
What Suppliers Will Ask For
Under Washington law, every sale is treated as retail unless the seller obtains a copy of the buyer’s reseller permit or an approved exemption certificate. Suppliers are also required to verify the validity of their customers’ permits electronically at least once per calendar year. Expect to hand over a current copy of your permit to any new supplier and to be re-verified periodically by suppliers you’ve bought from before.
Denial, Revocation, and the 50% Misuse Penalty
The DOR can revoke an active permit for four reasons:
- Improper use — you used the permit, or let someone else use it, to buy something that didn’t qualify for the exemption.
- Issued in error — the department made a mistake in granting it.
- No longer entitled — your business has changed and you’re no longer making wholesale purchases.
- Tax collection interest — revoking the permit serves the interest of collecting taxes owed.
Revocation comes in writing and takes effect on the date the notice specifies. You have the right to request a departmental review. If the permit was revoked for improper use, the DOR can refuse to reinstate it until all taxes, penalties, and interest on the improperly purchased items are paid in full. That restriction follows the business through reorganization, so restructuring the company to get a clean start won’t help if the old debts remain.
The financial hit for misuse is severe. If the DOR determines you improperly used a reseller permit to avoid paying sales tax, it assesses a penalty of 50% of the tax due on the improperly purchased item or service, on top of the full tax amount and any applicable interest and other penalties. General late-payment penalties under Washington’s tax enforcement provisions can stack on top of that.
The 50% penalty can be waived if the DOR finds the improper use resulted from circumstances beyond your control, but the exception is narrow. Intentional misuse, such as buying materials for personal use or your own business operations while claiming the resale exemption, won’t qualify for a waiver, and cases involving fraud can bring criminal charges.
