Seattle, WA Tax Help: IRS & State Back Taxes, Levies, Audits (2026)
Tax help in Seattle: who this guide is for
If you live or run a business in Seattle and the IRS or the Department of Revenue has started writing to you, this page explains what actually happens next, where the local offices are and what they can and cannot do, and how cases from King County get resolved without anyone taking a day off to sit in a federal building.
I am an Enrolled Agent, federally licensed to represent taxpayers before the IRS, and my firm handles back taxes, levies, audits and unfiled returns for clients across Seattle and its suburbs, including Bellevue, Tacoma, Everett, Redmond, Kent and Renton. Everything here is general information, not individual advice; the last section explains how to get a free review of your own notices.
Your IRS office in Seattle, and what it can actually do
The IRS Taxpayer Assistance Center serving Seattle is the IRS Taxpayer Assistance Center, Seattle, at 915 Second Ave., 32nd Floor, Seattle, WA 98174. By appointment only; call 844-545-5640. irs.gov's general weekday TAC hours are Monday through Friday, 8:30 a.m. to 4:30 p.m., and this office was also open on two of the IRS's special Saturday dates in 2026. Confirm hours and services in the IRS office locator. Other offices in the area include Tacoma Taxpayer Assistance Center (named by the IRS; address not confirmed on an official page), Everett Taxpayer Assistance Center (named by the IRS; address not confirmed on an official page) and Silverdale Taxpayer Assistance Center (named by the IRS for the Kitsap Peninsula; address not confirmed on an official page).
It helps to know what a Taxpayer Assistance Center is for. It can verify your identity, take a payment, give you transcripts and answer account questions. It does not negotiate: nobody at the counter can settle a balance, release a levy on their own authority or decide an audit. Those decisions sit with collection, examination and appeals units that work by mail, phone and fax, which is why most representation happens without a visit to the office at all.
The Taxpayer Advocate Service is different. It is an independent office inside the IRS that steps in when normal channels have stalled or a levy is causing hardship. The local office for Seattle: Taxpayer Advocate Service, Seattle office, 915 Second Avenue, MS W-405, Seattle, WA 98174, (206) 946-3707. It is a genuine safety valve, but it is not a shortcut around filing the missing returns or answering the notice in front of you.
The Washington side: Washington State Department of Revenue
Washington has no general personal income tax, so a Seattle taxpayer's state-level problem is almost always a business and occupation tax account, a sales tax account, or, for some individuals, the state's capital gains excise tax. Washington's legislature has also enacted a new state income tax on very high earners that does not begin collecting until a future tax year, so most residents will not encounter it for some time. The other common state letter in Seattle comes from a former state of residence.
Washington State Department of Revenue local office: 2101 4th Ave., Suite 1400, Seattle, WA 98121, 206-727-5300, open Monday through Thursday.
Federal and state collection are separate tracks: an IRS installment agreement does nothing to stop a Washington garnishment, and a state payment plan does not pause the IRS. Every Seattle case we take is mapped across both agencies before anything is negotiated. Our Washington state page covers the state side in detail.
Seattle taxes people forget about
Beyond the IRS and the Department of Revenue, Seattle has local obligations that show up as surprise bills, usually when a business or a rental has been running for a few years without them:
Seattle business license tax: anyone doing business in Seattle generally needs a business license tax certificate and must file a return every reporting period, even when no tax is owed; the city's own gross-receipts tax applies above an annual revenue threshold that is separate from the state B&O tax and is paid on top of it.
Payroll Expense Tax, known as JumpStart: Seattle's largest employers pay a tax on their Seattle payroll once both a company-wide payroll threshold and an individual high-compensation threshold are met in the same year, and the law specifically bars employers from withholding the tax out of employee paychecks.
Sweetened Beverage Tax: distributors of sweetened beverages in Seattle owe a per-ounce tax, with a reduced rate available to smaller, certified manufacturers.
Sales tax: Washington's retail sales tax is state-administered and destination-based, and the state recently expanded the list of taxable services, so a Seattle business that never collected sales tax on its services before may now owe it going forward.
King County property tax: the County Assessor values property and the Treasury bills and collects it in two installments each year.
The Seattle tax problems we see most
Every metro has its own pattern of tax trouble, because it has its own mix of work. In Seattle the cases that reach us most often look like this:
Tech workers with equity compensation: Stock options and restricted stock vesting over several years and across employers create basis-tracking problems, and a large sale can trigger Washington's capital gains excise tax on top of federal tax, a filing that many people moving from no-income-tax jobs elsewhere do not expect.
Aerospace and manufacturing workers around Boeing and its suppliers: Overtime, per diem and multi-state travel create W-2 mismatches and occasional multi-state filing questions that generate IRS notices.
Maritime, fishing and port workers: Share fishermen and similar maritime workers are often treated as self-employed for tax purposes, with no withholding and quarterly estimated payments that are easy to miss during a short, intense season.
Restaurant, hospitality and tourism workers: Tips, seasonal cruise-season staffing and multiple jobs around the waterfront generate IRS matching notices that need records and documentation to answer.
Construction and trades contractors: Cash-flow gaps between draws cause missed payroll deposits, and the city's own business license tax return is often the first filing skipped when cash is short.
Founders and employees at fast-growing Seattle companies: A growing company can cross the JumpStart payroll expense tax thresholds without anyone noticing, and because the employer, not the employee, owes the tax, it is usually discovered well after the fact.
Three things to know about Seattle cases
Washington has no general income tax, so a Seattle resident's tax problem is federal first; the two state-level exceptions are the capital gains excise tax on individuals and the legislature's new high-earner income tax, which does not start collecting until a later tax year.
A Seattle business can face three separate city and state tax systems at once: the state B&O tax filed through the Department of Revenue, the city's own business license tax, and, for large employers, the JumpStart payroll expense tax.
The IRS Taxpayer Assistance Center and the local Taxpayer Advocate Service office share the same downtown building at 915 Second Avenue.
How we work with Seattle clients
The process is the same whether you are in Bellevue, Tacoma and Everett or overseas. You sign IRS Form 2848, which lets us speak to the IRS for you and pulls the notices to our office instead of your mailbox; for state matters we file the state's own power-of-attorney form. We then pull your IRS account and wage transcripts and the state account history, so the first conversation is about real numbers rather than guesses.
From there the order is almost always the same: stop any active levy or garnishment, file whatever returns are missing (a return the IRS prepared for you is usually far higher than the real liability), and only then negotiate the balance through a payment plan, an offer in compromise, penalty relief or currently-not-collectible status, depending on what the financials support. Meetings are by phone or video, documents move through a secure upload link, and signatures are electronic. You never need to visit an office, and neither the IRS nor the Department of Revenue requires an in-person meeting for the vast majority of cases.
Frequently Asked Questions
Do I have to go to the IRS office on Second Avenue to resolve my problem?
No. The Seattle Taxpayer Assistance Center works by appointment through 844-545-5640 for tasks like identity verification and payments. Collection cases, audits and payment arrangements are handled by phone, mail and online, and a representative can do that work for you.
Washington has no income tax. Why would I have a state tax problem?
Washington taxes businesses rather than personal income: the Department of Revenue can assess business and occupation tax, sales tax, or, for some individuals who sell stock or a business, the state's capital gains excise tax. Residents also sometimes get letters from a state they used to live in.
I sold stock or a business and now owe Washington's capital gains tax. Can you help?
Yes, within what the rules allow. The capital gains excise tax applies to individuals, not businesses themselves, and only to gains the state treats as Washington-source, so we start by confirming whether the tax actually applies to your sale before anything is negotiated with the Department of Revenue.
My company is growing fast in Seattle. Do we owe the JumpStart payroll tax?
Possibly, once your citywide Seattle payroll and at least one employee's compensation both cross their respective thresholds in the same year. The tax is owed by the employer and cannot be withheld from employee paychecks, so it is worth checking before it becomes a surprise balance.
Can you handle both the IRS and the Washington Department of Revenue?
Yes. As an Enrolled Agent I am federally licensed to represent taxpayers before the IRS and before state tax agencies, including Washington's. We file IRS Form 2848 for the federal side and work directly with the Department of Revenue on any state business tax account, coordinating both so a plan with one agency does not leave the other unresolved.
