How Much Does It Cost to Start a Laundry Business in Washington? (2026)
Washington keeps a home laundry pro’s launch paperwork short — a tax registration, a free EIN, a trade name filing if you use a business name, and an optional $180 LLC. The one thing to meet head-on before your first order is the tax rule: Washington taxes laundry services in two parts — your business pays one of the taxes, and you collect the other from customers. If you already own a washer and dryer, the real costs are a starter kit of supplies and — when you’re ready — that LLC and an insurance policy. This post walks every line item. Our companion post walks the rules side in full: Washington rules for a home laundry business.

Step 1: The Washington paperwork — one tax registration, two taxes to understand
Taxes: register before your first order. The Washington Department of Revenue’s industry guidance puts laundry and dry-cleaning services among the retail services that “are subject to the Retailing B&O tax and you must collect sales tax.” That sentence carries two halves. Part one is yours: the Retailing B&O (business-and-occupation) tax is a tax on the business itself, paid on your income from the work — budget for it as a cost of doing business. Part two passes through your hands: on every order you add retail sales tax on top of your price, collect it from the customer, and remit it to the state — the customer’s money, never your revenue. Register with the Washington Department of Revenue (dor.wa.gov) before your first order. This post states no tax rate on purpose: rates depend on where the work is delivered, so confirm the current rate for your area with the Department of Revenue.
EIN: $0. A federal employer identification number is free from the IRS and takes about 10 minutes online. You may not legally need one as a solo operator, but it keeps your Social Security number off forms and makes a business bank account easier to open.
Trade name: register one if you use a business name. Doing business under a name that isn’t your own legal name? Register a trade name as part of your state business setup, before the name goes on bags, cards, or a booking page. Operating under your own legal name? This step may not apply at all.
LLC: $180, and it can wait. A Washington LLC costs a $180 state filing fee — Washington calls the filing a Certificate of Formation, filed with the Secretary of State — and filing online adds a small processing fee on top of the $180. An LLC legally separates the business from you personally. It is not required before your first order: many pros start as sole proprietors with a trade name and form the LLC once weekly revenue is steady, because the $180 buys the same separation in month six that it buys in week one. Business filings live at the state’s official portal: the Washington Secretary of State, Corporations & Charities (sos.wa.gov/corps), where filings run through the state’s CCFS system.
Step 2: The starter kit — your only real shopping list
Your washer and dryer: $0 if you use the ones you own. A home pro’s starter kit is small: a hanging scale (you’ll price by the pound), clear bags so customers get their laundry back in clean, sealed loads, labels or tags so orders never get mixed up, detergent options including an unscented one, and a clean, dedicated folding surface. A typical starter kit runs about $150–$300 depending on how much you already have at home — a ballpark for supplies, not a Washington statistic. Our general wash and fold startup costs breakdown goes deeper on kit choices.
Step 3: Insurance — the one cost not to skip
A general liability policy typically runs $300–$600/year for a small home service business. It turns a damaged garment or a spill in a customer’s home from a personal bill into an insurance claim. Plenty of pros launch without it and add it with their first regulars; budget for it in your first season, even if it isn’t in your first week.
Step 4: The second-machine question — your biggest cost can wait
The one purchase that tempts every new pro is a second washer and dryer. Resist it at launch. A second set is the right buy when your route is full and turnaround time — not demand — is what turns customers away; buying capacity before you have the pounds to fill it just converts your launch budget into idle machines. Start with the set you own, learn your real pounds-per-week, and let the numbers make this decision for you.
Two example budgets, with the math shown
Bare-bones start (sole proprietor, machines you own, lean starter kit):
- EIN: $0
- Starter supplies: $150
- Total: $0 + $150 = $150
Two setup steps sit outside that total, deliberately: registering with the Department of Revenue for the taxes (finish it before your first order) and, if you use a business name, registering the trade name. Neither changes the shape of the start: the kit is the launch cost.
Set-up-properly start (the same start, with the LLC formed from day one):
- EIN: $0
- LLC (Certificate of Formation): $180
- General liability insurance (middle of the typical $300–$600 range): $450
- Fuller starter kit: $300
- Total: $0 + $180 + $450 + $300 = $930
Both budgets assume you already own a working washer and dryer, and most pros land between the two totals — the LLC and the policy can arrive after your first regulars do. The B&O tax is not a launch line in either budget: it is an ongoing cost of doing business, paid on income as it comes in, and the sales tax you collect is never yours to count.
Step 5: Your booking page — free to join, your plan starts when you activate
The last launch cost is how you take bookings and payments. Gig apps bring orders and keep a percentage of every one, permanently — on a busy month, that percentage is the biggest “cost” in the whole business. Owning your booking page flips that. LaundryCareer gives Washington pros their own branded booking page with online booking, card payments, and pickup scheduling for free — nothing is charged when you sign up — you get paid on every order — you pick Plus ($8/month plus 4% when you get paid) or Unlimited ($20/month with 0%) when you activate (Stripe’s standard card fee still applies).
What comes in against those costs? Wash and fold is priced per pound, and typical prices commonly run about $1.50–$2.50 per pound with pickup and delivery (a typical range, not a state statistic). In Washington the sales tax rides on top of that price as its own line — collected by you, owed to the state. The illustration below is gross, figured before that tax line: an honest illustration, not a promise — one 20-pound order at $2.00/lb is $40, so five regular households ordering weekly is about $800/month, and fifteen regulars is roughly $2,400/month. Run your own numbers — your prices, your pounds, your regulars — on our income calculator. See how the whole launch fits together in the state’s biggest city in our Seattle laundry business guide.
Quick answers for Washington pros
Do I have to form an LLC before my first order? No. Many Washington pros start as sole proprietors — registering a trade name if they use one — and form the LLC later. The filing is $180 (Certificate of Formation), plus a small processing fee if you file online.
Do I really collect sales tax on wash and fold? Yes. The Dept. of Revenue counts laundry and dry-cleaning services as retail services, so you add retail sales tax on top of your price, collect it, and remit it. Your business also owes the Retailing B&O tax on its income — separate from the sales tax your customer pays.
What’s the biggest cost most new pros get wrong? Buying a second washer and dryer too early. Your owned machines plus a $150–$300 starter kit can carry a real route; add capacity when full routes — not hope — demand it.
Do these costs change in a smaller Washington city? Barely. The state fees are the same everywhere in Washington and the EIN is free; what changes is your local sales tax rate and your city’s home-occupation rules.
