Washington · Sales tax closure
Close a Washington business tax account.
Washington is the one state where closing with the Department of Revenue starts the others. Revenue shares what you submit with Business Licensing, Employment Security, and Labor and Industries. The excise tax return and payment are still due by the 25th of the following month, and inventory you kept can carry use tax.
Who you are dealing with
Washington Department of Revenue
- Handles:
- Business licence, retail sales tax, and Business and Occupation tax, all reported on the combined excise tax return
- System:
- My DOR
- Form:
- Close my account in My DOR, described by Revenue as the fastest way, or the paper Business Information Change Form. Tick the Business Closed box on the final excise tax return and enter the date the business closed
State fee. $0 to close. What can cost money is use tax on inventory converted to personal use where sales tax was never paid on it, which is a tax bill rather than a fee.
When you have to close
You close when the business stops operating in Washington. Tick Business Closed on the final excise tax return and enter the closing date, which is what tells Revenue this is the last one.
Final returns come first
Complete the excise tax return and pay all outstanding tax by the 25th of the following month. Account for use tax on any inventory converted to personal use where sales tax was not paid. Washington also asks you to keep the records for five years after closing.
How long it takes
Washington does not publish a turnaround for the closure itself. The item with a date on it is the excise tax return, due with payment by the 25th of the month following. For a corporation the Revenue Clearance Certificate is usually the slow step, because the Secretary of State will not accept a dissolution without it.
What we do
We confirm which accounts are open, file the final returns if they are still outstanding, submit the cancellation to each agency, and follow up until both are confirmed closed. You get the written confirmations. One flat price, and the state charges nothing to close.
What makes Washington harder than average
- Washington shares your closure, and that is genuinely unusual. Revenue states that the information you provide is shared, where applicable, with Business Licensing, your Unemployment Insurance account at Employment Security, and your Workers Compensation account at Labor and Industries. Almost every other state makes you tell each agency yourself. Do not assume this behaviour anywhere else.
- Shared notice does not file your returns. Employment Security still wants the final quarterly report within 10 days of closure and still wants it even if there was no payroll. Revenue telling them you closed is not the same as satisfying that.
- Inventory you kept can carry use tax. Anything you took for personal use on which sales tax was never paid is a use tax question on the final return, the same trap as Texas, and it is the part a business winding down rarely values before filing.
- A corporation cannot dissolve until Revenue says so. The Secretary of State wants a Revenue Clearance Certificate with the dissolution, so the tax side has to be clean before the entity side can finish. Starting at the Secretary of State means discovering this in the wrong order.
- Five years of records. Washington asks businesses to keep records for five years after closing, which is longer than most people plan for and worth knowing before the filing cabinet goes.
Questions and answers
Do I have to close separately with Employment Security and Labor and Industries?
Usually not for the notification itself. Revenue states that the information you provide when closing is shared, where applicable, with Business Licensing, Employment Security, and Labor and Industries. You do still owe Employment Security your final quarterly report, and that is a separate obligation from being notified.
How do I mark the excise return as final?
Tick the Business Closed box and write the date your business closed. The return and payment are due by the 25th of the following month.
I have stock left that I kept for myself.
That can create use tax if sales tax was never paid on it. It goes on the final return. Tell us roughly what is left and we will account for it rather than leaving it to surface later.
Why is my dissolution stuck?
Most likely the Revenue Clearance Certificate. A dissolving corporation needs one from the Department of Revenue to file with the Secretary of State, and Revenue will not issue it to a business that is not current.
What do you need from me to start?
The legal name and UBI number, the closing date, the figures for the final reporting period, whether you are a corporation needing a clearance certificate, and roughly what inventory was retained.
