The Real Cost of a Washington LLP — What You Pay and When

The upfront cost of a Washington LLP centers on the state filing that registers the partnership as a limited liability partnership with the Secretary of State, submitted through CCFS. This is the fee that converts your general partnership into a registered LLP on the state's records and gives you your Unified Business Identifier (UBI) number.

What the registration fee covers

The state filing fee pays for the state to review and record your registration and to add the LLP to its public database. It is a single charge at formation, not a recurring one. The receipt card on this page reflects the current amount so you are working from live figures rather than a number that may have drifted.

Online versus paper

Washington processes online filings through CCFS much faster than paper filings sent by mail. Filing online is the standard path for most partnerships. If you need your registration handled unusually quickly, Washington offers expedited processing for an additional fee, useful when a deadline — a lease, a contract, a bank appointment — is bearing down.

An LLP is not a one-and-done expense. Washington attaches ongoing costs to keeping the partnership active and in good standing, and budgeting for them from the start prevents the unpleasant surprise of a lapse.

Annual report

Every registered Washington LLP files an annual report with the Secretary of State, and that report carries a state fee. The report keeps the state's record of your agent, principal office, and partner information current. It is not a tax return and it does not report your finances — it is a maintenance filing. The receipt card shows the current annual report fee. Missing the deadline can lead to loss of good standing, so treat this as a fixed yearly cost.

Registered agent service

If you use a commercial registered agent instead of serving as your own, that service charges an annual fee. This is separate from anything the state charges. What you get for it is a professional Washington address kept out of your personal record, guaranteed availability to accept service of process, and prompt forwarding of documents — plus continuity that does not depend on any one partner staying at the firm.

The cost that surprises businesses new to Washington is the Business & Occupation (B&O) tax. Washington has no personal or corporate income tax, but it makes up for it with a gross-receipts tax that applies broadly.

How the B&O tax works

The B&O tax is levied on the gross receipts of a business — the total revenue it brings in — rather than on net profit. That means a business can owe B&O tax even in a year it does not turn a profit, because the tax is measured on revenue, not income. The tax is administered by the Department of Revenue, and the rate depends on the classification of your business activity, with different rates for services, retailing, and other categories.

Why it matters for budgeting

Because it is measured on gross revenue, the B&O tax scales with how much business the LLP does, not with how profitable it is. For a professional services LLP, this is a real and recurring cost that should be modeled into pricing. It is entirely separate from your Secretary of State registration and annual report — a different agency, a different filing, a different schedule.

Sales tax, where applicable

If your LLP sells taxable goods or certain services, you also collect and remit Washington sales tax through the Department of Revenue. This is money you collect from customers rather than a cost of the entity itself, but it is another filing obligation to track.

Beyond the headline state fees, a realistic budget for a Washington LLP includes several items that partnerships routinely forget until they hit them.

Business licensing

Most Washington businesses must register through the state's Business Licensing Service, and there can be state and city license fees layered on. Depending on your industry and the cities you operate in, city endorsements and professional licenses add their own costs. These are separate from the LLP registration.

Professional licensing

Because LLPs are common among licensed professionals, the cost of maintaining each partner's professional license — and any firm-level registration your board requires — is part of the true cost of operating, even though it has nothing to do with the LLP filing itself.

Foreign registration

If your LLP was formed in another state and is registering to do business in Washington as a foreign LLP, there is a filing fee for that authority, and you typically need a certificate of good standing from your home state, which your home state may charge for.

Changes and amendments

Updating your registered agent, changing your principal office, or amending other details in your record may carry state fees when you file the change through CCFS. These are occasional rather than recurring, but they belong in a complete picture of costs.

When you register a Washington LLP through Mainstay Filing, the amount shown on the receipt card is the amount charged. We do not advertise one figure and bill another. The card itemizes the state filing fee and our service so you can see exactly what goes to Washington and what goes to us before you commit.

What Mainstay Filing charges for

Our flat yearly fee covers preparing your LLP registration accurately, submitting it through CCFS, returning your filed record, and serving as your registered agent for every year we represent you. The annual report is part of that same fee too — we prepare and file it when it comes due, not as an add-on service. State fees — the registration fee, the annual report fee, expedited handling if you choose it — are passed through as the state sets them.

What you control

Some costs are optional. Expedited processing is only worth paying for if you have a real deadline. A commercial registered agent is a choice only when you handle compliance on your own; when Mainstay serves as your agent, the role rides inside the yearly fee rather than appearing as a line of its own. And the B&O tax and licensing costs are a function of your business activity, not the LLP filing — but knowing they exist from day one is the difference between a budget that holds and one that springs leaks.
