Food truck owners crossing into Washington
What does an out-of-state food truck LLC need to operate in Washington?
The $10 card comes before the $180 filing
The first Washington requirement a food truck touches is not the corporate one. Every food worker in Washington must hold a valid food worker card, per chapter 246-217 WAC, and the card costs $10 from a local health department or the state's authorized online course.
The card is personal, not corporate. Every person handling food on the truck needs one, the card or a copy must be available at work for the health department to check during an inspection, and a worker may start up to 14 days before getting the card if the employer provides the food safety training.
No card from another state works here. The Department of Health is explicit that a Washington State food worker card is required to be employed as a food worker in the state, so an out-of-state crew crossing the line takes the Washington course, however many food handler permits it already holds.

14 daysThe Department of Health states a Washington food worker card is required in the state, no other state's card is accepted, and a worker may start 14 days before the card with employer training. — Washington State Department of Health, retrieved 2026-09-29
The permits are county-shaped, not state-shaped
Washington's food safety rules live at the county level. Local health departments offer the food worker training, test, and card, and the Department of Health routes food establishment operators to their local health department for information specific to their operations.
That geography is the food truck's defining cost. A truck working festivals in three counties deals with three health jurisdictions, each with its own permit for the food establishment, each with its own inspections, and a commissary arrangement each county accepts.
The corporate filings, by contrast, are one-and-done statewide: the Foreign Registration Statement with the Secretary of State and the tax registration with the Department of Revenue cover the whole state. A food truck's compliance perimeter is drawn by the county map, not the state line, which is what separates this trade from the salon owner with one fixed address.

The 30-day carve-out a festival schedule defeats
The corporate question for a food truck is whether the Washington stops add up to doing business. The statute's carve-out for an isolated transaction completed within thirty days, not in the course of repeated transactions of a like nature, is what a single festival run fits and a season does not.
One three-day festival is an isolated transaction. A summer of weekend stops, even at different events, is a course of repeated transactions of a like nature, and the statute's exclusion is written in exactly those words.
Crossing the line regularly also settles the tax side. Physical presence in Washington that need only be demonstrably more than a slightest presence gives the state substantial nexus under RCW 82.04.067, and a truck parked in Washington on service days is property in the state. The doing-business page and the B&O page carry both tests in full.

The corporate filing, once the season is real
Once the stops are a schedule, the corporate filing follows the same path as every other trade here. The Foreign Registration Statement costs $180 plus an online processing charge, with a certificate of existence from the home state attached, dated within 60 days of the submission.
The name question is worth a look before the certificate is ordered. A truck brand that sells sauces or merch on the side may have a name worth protecting in Washington records, and the registration is what puts the LLC's name on the state's searchable record.
The penalty for skipping it lands in the same place for a truck as for a contractor. An unregistered LLC cannot maintain its own action in a Washington court, which matters the first time a caterer or an event promoter owes money, and the bar lifts only after the registration and the back fees are paid.

What a food truck does not need from the state
Washington does not run a state food truck license the way it runs an electrical contractor license. The trade's state-level pieces are the food worker card, which is personal, and the food safety rules the counties enforce, which attach to the operation.
What the truck does not escape is the tax side of the food business. The Department of Revenue's registration is where the tax classifications for the food line get sorted out, and an out-of-state LLC with property in Washington, a truck on a service day included, has substantial nexus on the physical-presence limb alone.
The honest budget for a first Washington season is the $10 per crew member, the county permits, the $180 corporate filing, and the tax registration. The dishonest one is the season that starts on the county line with a card from home and a schedule of weekends. The expansion checklist orders the rest, and the cost breakdown prices the corporate side of it.
The Department of Revenue requires an LLC to file with the Secretary of State before the Business License Application, which assigns the UBI number used for taxes. — Washington Department of Revenue, retrieved 2026-09-29
Questions
Can my out-of-state food truck use its home state health permit in Washington?
No. Washington's food worker card does not accept cards from other states, and the food establishment permits are issued by the local health jurisdiction where the truck operates. Contact the local health department for each county before booking stops there, because the Department of Health routes operators there for operation-specific requirements.
How many food worker cards does my crew need?
One per person handling food, each at $10. The card is required per chapter 246-217 WAC, it must be with the worker or a copy available at work for health department checks during inspection, and a new worker may start up to 14 days before the card if you provide the food safety training.
Does one weekend event in Washington trigger the LLC registration?
Not by itself. An isolated transaction completed within thirty days, not in the course of repeated transactions of a like nature, is on RCW 23.95.520's list of activities that are not doing business. One event fits that; a season of them does not.
Where do I get the food worker card from out of state?
All local health departments offer the training, test, and card online, and the only authorized online training program is www.foodworkercard.wa.gov. Other websites that appear to offer a similar card are not valid in Washington.
