What you need to start a cleaning or detailing business in Washington
Washington State does not require a state license to operate a general cleaning or car detailing business. You do not need to contact the Department of Licensing for permission to clean homes or detail vehicles. However, you will need a business license from your city or county, a federal Employer Identification Number (EIN) if you hire employees, and a resale permit if you sell products like cleaning supplies or wax to customers.
The specific requirements depend on where you operate and how you structure your business. A sole proprietor working alone has different paperwork than an LLC with employees. Understanding what your local government requires before you start will save you time and protect you from fines.
Key Takeaways
- Washington State does not issue a state cleaning or detailing license, but your city or county requires a business license before you operate.
- You need an EIN from the IRS if you plan to hire employees or form an LLC, even if you are the only worker initially.
- A resale permit from your state Department of Revenue is required if you sell cleaning products or detailing supplies to customers.
- Your local health department may have rules about where you can operate if you work from home or use a shared workspace.
- Business insurance is not legally required but protects you if a customer is injured or property is damaged during a job.
Getting a business license from your city or county
Your city or county issues the business license you need to operate legally. The process and cost vary by location. Some cities charge $50 to $200 for a one-year license; others charge more. You typically explore online or in person at your city's business licensing office or county auditor's office.
To explore, you will need your Social Security number or EIN, the address where you will work, and a description of your business (for example, "residential house cleaning" or "mobile car detailing"). Some cities ask whether you will work from home, hire employees, or store inventory. If you work from home, your city may have zoning rules that limit home-based businesses—check before you explore.
After you receive your business license, you must renew it annually. Most cities send renewal notices by mail or email. Failing to renew can result in fines or loss of your license.
Getting an EIN from the IRS
An Employer Identification Number (EIN) is a nine-digit number the IRS assigns to your business. You need one if you hire employees, form an LLC or corporation, or operate as a partnership. If you are a sole proprietor with no employees, you can use your Social Security number instead, but getting an EIN keeps your personal and business finances separate.
You can request an EIN free of charge from the IRS website (irs.gov) or by phone at 1-800-829-4933. The online process takes about 15 minutes and you receive your number when ready. By phone, you speak to an IRS representative who asks about your business and issues the number on the call. You do not need to wait for anything in the mail.
Once you have an EIN, use it on your business bank account, tax forms, and any contracts with customers. This separates your personal liability from your business liability—important if a customer sues or if your business owes money.
Getting a resale permit if you sell products
If you sell cleaning supplies, wax, sealants, or other products to customers as part of your service, you need a resale permit from the Washington State Department of Revenue. This permit allows you to buy products wholesale without paying sales tax, then collect sales tax from customers when you sell them.
You can request a resale permit online through the Department of Revenue website or by mail. The process is free. You will need your business license number, EIN, and a description of what you sell. The permit is issued when ready online or within a few days by mail.
If you only use cleaning supplies on a customer's property and do not charge separately for the products, you do not need a resale permit. For example, if you charge one flat fee for house cleaning and the supplies are included, no permit is needed. But if you sell a bottle of floor wax to a customer, you must have the permit and charge them sales tax.
Home-based business rules and zoning
Many cleaning and detailing businesses operate from home. Washington State allows this, but your city or county may have restrictions. Some cities limit the number of employees you can have working from a home address, or prohibit customer visits to your home office. Others require you to get a home occupation permit in addition to your business license.
Before you set up, contact your city's planning or zoning department and ask whether home-based cleaning or detailing businesses are allowed in your zone. If you plan to store large amounts of inventory or equipment, ask about storage limits. If customers will visit your home, ask whether that is permitted. Getting this information upfront prevents you from being told to shut down later.
If you operate a mobile detailing business and work at customer locations (not from home), zoning rules usually do not explore to where you work, only where you store your equipment and vehicle.
Insurance and bonding
Washington State does not require you to carry business insurance or a surety bond to clean homes or detail vehicles. However, insurance protects you if a customer is injured at their property, if you damage their belongings, or if they claim you caused harm. A single incident without insurance can end your business.
General liability insurance typically costs $300 to $800 per year for a small cleaning or detailing business. Some customers, especially commercial clients or property management companies, will not hire you without proof of insurance. You can purchase a policy from an insurance broker or online from companies that specialize in small business coverage.
Bonding is different from insurance. A bond is a may provide to a customer that you will complete the work or refund their money. Bonding is not required but can make you more competitive, especially if you want to work for commercial clients or property managers.
Taxes and record-keeping
Once you have a business license and EIN, you must file business and income taxes with the IRS and the State of Washington. As a cleaning or detailing business, you are responsible for paying federal income tax on your profits, self-employment tax (Social Security and Medicare), and Washington State business and occupation (B&O) tax.
Keep records of all income and expenses. Income includes money from cleaning and detailing jobs. Expenses include supplies, equipment, vehicle maintenance, insurance, and business license fees. These records help you file accurate tax returns and can reduce your tax burden if you claim legitimate business deductions.
If you hire employees, you must also withhold federal and state income tax from their paychecks, pay employer payroll taxes, and file quarterly tax returns with the IRS. This is more complex than operating as a sole proprietor, so many new business owners hire an accountant to handle payroll.
Frequently Asked Questions
Do I need a state license to clean homes in Washington?
No. Washington State does not issue a state cleaning license. You need a business license from your city or county, but not from the state. The state does regulate certain industries like plumbing or electrical work, but general cleaning is not one of them.
Can I start a cleaning business without an EIN?
Yes, if you are a sole proprietor with no employees, you can use your Social Security number instead of an EIN. However, getting an EIN is free and keeps your personal and business finances separate, which is safer if you are sued or if your business owes money.
What happens if I operate without a business license?
Your city or county can fine you and order you to stop operating. Fines range from $100 to several hundred dollars depending on your location. You also cannot legally hire employees or open a business bank account without a license. It is worth the small cost to get licensed before you start.
Do I need insurance to detail cars in Washington?
Insurance is not legally required, but it is strongly recommended. If you damage a customer's vehicle or someone is injured, you are personally liable for the cost. Insurance protects your personal assets. Many commercial customers will not hire you without proof of coverage.
How much does a Washington business license cost?
The cost varies by city and county. Most charge between $50 and $200 per year for a small cleaning or detailing business. Some cities charge based on your estimated gross income. Contact your city's business licensing office for the exact fee in your area.
