| Authorization, direction, and primary benefit | No general state preapproval, employer-direction, ratification, or primary-benefit test stated |

| Employer policy, preapproval, and caps | No general statutory preapproval, specification, cap, deadline-extension, de minimis, or nonwaiver rule identified; RCW 49.52.050 protects wages already owed by statute, ordinance, or contract |
| Payment deadline, method, and interest | No general state reimbursement deadline, payment method, advance or stipend rule, or reimbursement-interest rule; RCW 49.48.010 separately covers bank fees caused by a dishonored wage instrument |

Washington has no general reimbursement mandate
The current Title 49 index identifies chapters for minimum wages and labor standards, wage payment and collection, and wage deductions and rebates. It contains no general chapter requiring an ordinary private employer to repay necessary employee business expenses.
Washington therefore supplies no universal necessary-expense test, mileage rate, employer-direction or primary-benefit standard, employee-fault schedule, receipt deadline, policy cap, payment clock, or reimbursement-specific remedy. A right created by a contract or a narrower law would need its own legal basis.
What trips people up
RCW 49.48.010(1) does use the word “reimburse,” but only for a bank fee charged after an employer's wage instrument is returned for insufficient funds. The employee must present the instrument within 30 days. That narrow paycheck-fee rule does not cover mileage, phones, tools, travel, supplies, or other ordinary business expenses.
RCW 49.52.050(2) separately prohibits a willful, intentional deprivation of wages by paying less than the amount the employer is obligated to pay under a statute, ordinance, or contract. It protects an existing wage obligation; it does not itself make every employee-paid expense reimbursable.
Common questions
Must every Washington employer reimburse mileage?
No general Title 49 provision creates a statewide mileage rate or universal mileage-reimbursement duty for ordinary private employment.
Is there a statewide receipt-submission deadline?
No general business-expense submission procedure appears in Title 49. The 30-day presentation rule in RCW 49.48.010(1) applies only to a dishonored wage instrument and the resulting bank fee.
Can an agreement create a reimbursement obligation?
An agreement may supply an independent obligation. RCW 49.52.050(2) expressly refers to wages an employer is obligated to pay by contract, but it does not define which business expenses a contract covers or create a universal expense entitlement.
