Seattle, WA Towing Company License Guide (2026)

First decision: what kind of towing company are you?

Washington defines a registered tow truck operator around impounding, transporting, or storing unauthorized vehicles and disposing of abandoned vehicles. Seattle’s Chapter 6.214 uses a similar definition. That is the core path covered here.

Washington also has a separate Vehicle Transporter license for transporting vehicles a business does not own. If you only perform owner-requested roadside or transport work and never impound unauthorized vehicles, ask DOL which endorsement fits your services and ask Seattle whether Chapter 6.214 applies.

Seattle’s tow-company regulatory license

Seattle says a towing company covered by its rules must have the city business license tax certificate and a regulatory towing license. The regulatory license costs $525 per year, runs January 1 through December 31, and is not prorated.

What Seattle asks you to prepare

The City tells applicants to gather:

• state and local business registration numbers;
• physical addresses of secured vehicle-storage areas;
• class, plate number, and VIN for each tow truck;
• impound rates;
• the state inspection report for each storage lot; and
• the state permit for each tow truck.

This is why the state and location work comes first. Seattle also says changes to application information must be reported within seven days.

The general Seattle certificate is separate

Seattle’s business-license page has a narrow 2026 exemption for an out-of-city business with no Seattle place of business and no more than $4,000 of annual Seattle gross income. It expressly says that exemption does not cover regulatory licenses or specialized permits. Because the towing page says tow companies need both licenses, a small out-of-city operator should confirm the general-certificate treatment rather than assuming the towing license disappears.

Washington RTTO license: the state layer

Washington DOL issues the RTTO license, but the Department of Revenue’s Business Licensing Service processes it as an endorsement on the state business license.

DOL says you must complete two major prerequisites before applying: local zoning approval and a business-site inspection. The application package includes the Business License Application, Vehicle Transport/Disposal Addendum, official fee information, the inspection report, and a driver list.

Bond, insurance, and truck permits

The current state requirements include a $5,000 bond, at least $100,000 liability insurance for bodily injury or property damage per occurrence, and $50,000 garage-keepers/legal liability coverage for vehicles in the operator’s custody.

The current DOL fee schedule lists the RTTO original license at $100 and renewal at $100. Each tow-truck permit is $50 per truck for the original permit and $50 per truck for renewal. DOL says vehicle-transport and disposal business endorsements renew every year.

If you add another storage or impound site away from the main business location, review the separate RTTO branch-license process. DOL says each additional vehicle-storage or impound area away from the main location must be licensed separately. The branch license itself currently has no license fee, although processing fees may apply.

Your location is part of the license

An RTTO location affects zoning approval, storage security, inspections, vehicle redemption, and the state license. Do not lease a yard and assume it can be approved later.

If the business or tow yard is in Seattle

Use SDCI’s property and permit research tools before committing to an address. Seattle classifies towing services as a transportation-facility use, and its use-intensity guidance lists towing services with outdoor storage as a higher-intensity use.

SDCI says uses must be established by permit. A new or changed use can require an establish-use or construction permit. The answer depends on the exact zone, established use, site history, and project.

Secure storage is a state requirement too

Washington requires the RTTO application to list secure storage and redemption areas. Additional storage lots must be approved before use and inspected annually. State rules set fencing, gate, and security standards, with limited waiver provisions. A home office does not replace the need for a compliant licensed storage setup when you take vehicles into custody.

Costs and Seattle private-property impound limits

There are two different kinds of numbers to keep straight: government licensing costs and what you are allowed to charge a vehicle owner. Do not mix them.

Seattle private-property impound caps effective April 20, 2026

Seattle limits what tow companies may charge for private-property impounds. These caps do not apply to private accident tows. The City’s current maximums are:

The City says additional labor and service fees are not allowed for Class A, D, or E private-property impounds beyond the authorized categories. The $15 City impound fee must be shown separately on the receipt and is not subject to sales tax.

Operating rules that affect daily work

RTTO rules continue after the license is issued. Key examples include:

• Hours and releases: normal business hours are 8:00 a.m. to 5:00 p.m. on weekdays, excluding holidays. When closed, an operator must post a contact number and keep personnel available to release impounded vehicles within the rule’s required period.
• Posting: redemption locations must display required licenses, charges, redemption rights, complaint information, and tender information.
• Custody and records: vehicles must remain in a secure registered area, and operators must keep required transaction records and a master log.
• Private impounds: the RTTO cannot act as the property owner’s agent to sign the impound authorization or independently choose the vehicle for impound.

Seattle adds its own private-impound receipts, fee limits, complaint enforcement, and $15 City impound fee.

Taxes, business setup, and employees

Washington taxes

Washington DOR says towing charges are generally reported under Retailing B&O tax and retail sales tax must be collected. Limited reseller-permit situations can apply when a repair shop properly resells the towing service, but that is not a general exemption.

Use the Washington Business Licensing Service for the state business license and endorsements. Keep trade names, locations, employees, and ownership information consistent with RTTO and Seattle records.

Use the Washington Business License Application to register as an employer. DOR says that filing sets up workers’ compensation with Labor & Industries and unemployment insurance with the Employment Security Department; new hires must also be reported through the state process.

If you hire drivers or other employees

Seattle B&O changed in 2026

Starting January 1, 2026, Seattle increased its B&O liability threshold from $100,000 to $2 million and added a $2 million standard deduction for taxpayers above the threshold. Businesses below the threshold may owe no Seattle B&O tax but still must file the applicable return and report gross revenue.

For 2026, a new Seattle general-business-license applicant pays the Tier 1 fee of $73 by default, or $37 if starting July 1 or later. An LLC, trade name, or EIN does not replace the tow licenses. See BLG’s business license vs. LLC vs. DBA vs. seller’s permit guide and Washington business license guide for the broader setup layer.

Seattle, King County, and where your yard is actually located

Seattle is in King County, but King County is not a second general business-license office for an ordinary business located inside Seattle. King County’s Local Services licensing program says its general local business-license functions apply to businesses in unincorporated King County and to specific county-regulated activities.

The important line for a towing company is the actual business and storage address. If your yard is inside Seattle, Seattle zoning and land-use rules apply to that site. If it is outside Seattle, the local zoning authority for that other city or unincorporated King County must handle the location approval required by the state RTTO process.

You can use BLG’s Seattle business license guide for the broader city layer and the King County business license guide when you need to sort city versus unincorporated-county jurisdiction.

Important 2026 changes

Private-property impound rates changed April 20

Seattle’s current private-property maximum-fee schedule took effect April 20, 2026. Do not reuse a 2025 rate sheet.

Seattle business tax rules changed January 1

The Seattle B&O threshold moved to $2 million, a $2 million standard deduction was added, and the small out-of-city general business-license exemption increased from $2,000 to $4,000 of annual Seattle gross income. Regulatory licenses remain outside that exemption.

Streetcar-obstruction impounds changed March 18

Washington HB 2495 took effect March 18, 2026. It allows an authorized representative of a city with more than 700,000 residents to direct an immediate RTTO impound when a vehicle in streetcar right-of-way obstructs streetcar operations or jeopardizes public safety. Legislative staff identified Seattle as the city affected. It expands who may authorize that narrow impound; it does not award towing contracts.

What if the application path does not fit your situation?

If a form seems to force the wrong business type, stop before changing your answers just to make the portal accept them. Save the error or question, then contact the agency that owns that layer. Use Seattle Consumer Protection for the city tow-company classification, SDCI for the site, and Washington DOL/Business Licensing Service for the RTTO or vehicle-transporter endorsement.

If two agencies give you different instructions, ask each one which specific license, code section, or form controls its part. A towing company can legitimately have several layers at once.
