• Register Your Business: Before applying, ensure your business is registered with the Washington Secretary of State if applicable (corporations, LLCs, partnerships).
• Apply Online: Use the Washington State Department of Revenue’s Business Licensing Service (BLS) website to apply for your seller's permit. This is the fastest and most efficient method.

• Receive Your Permit: After processing, you will receive your seller's permit number, which must be displayed or referenced on sales tax returns.

Operational Considerations

• Sales Tax Collection: Once you have the permit, you must collect sales tax on taxable sales and file returns regularly with the Department of Revenue.
• Recordkeeping: Maintain detailed sales records and tax collected to ensure compliance and simplify bookkeeping and reporting.
• Renewals and Updates: As of 2026, seller's permits do not typically require annual renewal but update your account promptly if your business information changes.
• Integration with Payroll and Accounting: Consider automating sales tax collection and reporting through accounting software to streamline compliance.
