WA DOR Login: My DOR Tax Filing, Business Licenses & SAW Access

To complete a WA DOR login, navigate directly to the official My DOR portal at https://secure.dor.wa.gov, enter your SecureAccess Washington (SAW) User ID and Password, and click Log in to My DOR. Immediately following credential verification, you must complete a mandatory Multi-Factor Authentication (MFA) challenge using a one-time verification code sent to your registered email or mobile number. The My DOR online system is the centralized digital gateway operated by the Washington State Department of Revenue for business owners, tax preparers, and individual taxpayers. Through a single unified SAW profile, users manage Unified Business Identifier (UBI) accounts, file Business and Occupation (B&O) combined excise tax returns, renew state business license endorsements, and submit Working Families Tax Credit applications without mailing paper forms.

Required Credentials & System Prerequisites

• SecureAccess Washington (SAW) User ID & Password: A registered SAW account is required for all users. Your SAW User ID must be between 4 and 32 characters (not case-sensitive), paired with a strong password. You can use an existing SAW credential created for other state agencies like L&I, ESD, or DOL.
• DOR Letter ID & UBI/Account Number (First-Time Account Linking): To link a business tax account or license to your profile for the first time, you need your 9-digit Unified Business Identifier (UBI) or Tax Registration Number, plus the official Letter ID printed on physical correspondence mailed by the Department of Revenue.
• Verified MFA Contact Channel: Active access to the primary email address, secondary backup email, or SMS-capable mobile phone number bound to your SAW profile to receive real-time Multi-Factor Authentication security codes.
• Supported Web Browser Configuration: Up-to-date versions of Google Chrome, Mozilla Firefox, Microsoft Edge, or Apple Safari with cookies enabled and pop-up blockers disabled for dor.wa.gov and secure.dor.wa.gov.

How to Sign In to WA DOR Online

1. Open your web browser and navigate directly to https://secure.dor.wa.gov (or visit https://dor.wa.gov and click the Log in button in the top right corner). Going directly to the My DOR login screen bypasses the double sign-in required when routing through the external SAW portal.
2. Enter your credential into the SAW User ID field and type your secret key into the Password field. Toggle Show Password if you need to verify character accuracy before submitting.
3. For First-Time Users vs. Returning Users: Returning users simply click Log in to My DOR. First-time users must click Sign up next to New user? (or click Check if you have a Secure Access Washington (SAW) user ID to verify if an email is already registered with another Washington agency). After creating a new SAW profile, log in and select Access your account using a letter ID on the services screen to link your tax or licensing records.
4. On the Multi-Factor Authentication Choose Method screen, select your preferred delivery option (registered email address or mobile SMS text message). Retrieve the one-time numeric code, paste it into the Multi-Factor Authentication Enter Code field, check Yes, remember my device if using a private workstation, and click Submit.
5. Once authenticated, you will land on the My DOR Services page. Click Get Started to enter your primary account summary dashboard, where you can select specific business entities or individual tax programs.

Excise Tax Filing, Business Licensing & Tax Credits

• Combined Excise & B&O Tax Filing: File monthly, quarterly, or annual Business and Occupation (B&O) tax returns, retail sales tax reports, and leasehold or forest tax returns. Users can upload bulk data files, save draft returns, amend prior filings, or use the express Report no business activity tool.
• Business Licensing Service (BLS) Management: Apply for a new Washington Business License, renew annual license endorsements, register or cancel a Doing Business As (DBA) trade name, and update physical location or mailing addresses under the Manage Licensing Account panel.
• Third-Party Tax Preparer & Administrator Delegation: Manage account permissions by granting secure role-based access to CPAs, bookkeepers, or automated tax compliance platforms like Avalara (including adding secondary 2FA email routing under Manage My Profile).
• Working Families Tax Credit & Unclaimed Property: Individual residents can submit applications and track refund disbursements for the Working Families Tax Credit, file consumer use tax returns, and submit digital claims for unclaimed money or property held by the state.

Fixing Common Login Errors & MFA Lockouts

Account Security & Phishing Prevention

• 🔒 Guard Against Business License Renewal Phishing: The Washington Department of Revenue warns businesses about fraudulent emails claiming your license or endorsement is expiring and demanding immediate payment via third-party links. Authentic automated renewal notifications only come from [email protected] and simply instruct you to read a secure message inside your My DOR inbox.
• 🔒 Verify Official State Domains: Never enter your SAW User ID or password on any website that does not end in .wa.gov. Always verify that your browser address bar displays https://secure.dor.wa.gov before authenticating.
• 🔒 Configure Redundant MFA Channels: Log in to your SAW profile settings and register both an Additional Email Address and a Mobile Phone Number. Having multiple verified channels prevents business-halting lockouts if a primary email server goes down on tax filing day.
• 🔒 Never Share SAW Credentials with Third Parties: Instead of giving your personal SAW username and password to an accountant or employee, use My DOR's built-in Manage Account Permissions tool to assign them an independent user role that can be revoked at any time.
