Tax Attorney in Seattle, WA
Federal IRS representation for Seattle individuals and businesses — audits, back taxes, liens, levies, Offer in Compromise filings, and U.S. Tax Court petitions in the Tom Lantos U.S. Courthouse on Stewart Street. The King County tech corridor concentrates Amazon, Microsoft, Starbucks, T-Mobile, Boeing, and Costco equity exposure at a depth few cities can match. The 2022 Washington Capital Gains Tax under RCW 82.87 (upheld in Quinn v. State 2023) sits on top of a Business & Occupation gross-receipts regime that operates on a different axis than federal income tax. The California Franchise Tax Board still chases many post-2020 Bay Area transplants under FTB Publication 1031 residency rules. Federal IRS practice plus Washington Department of Revenue work, handled together.

If you owe back taxes in Seattle, here is what changed in 2026
The IRS resumed full passport-revocation referrals under IRC §7345 for taxpayers with seriously delinquent federal balances over the inflation-adjusted threshold ($62,000 for 2026). Seattle engineers on H-1B status, founders with international banking, and remote-work professionals with travel to Asia or Europe face real revocation exposure. Three Seattle-specific 2026 pressure points sit on top of that: the Washington Department of Revenue is in its third compliance cycle on the 7% state Capital Gains Tax (RCW 82.87) following the Washington Supreme Court's Quinn v. State ruling, with first-cycle nonfilers now in audit; the California Franchise Tax Board continues to pursue Seattle tech workers who relocated from the Bay Area on equity that vested before the move, citing California source-of-income rules under Cal. Rev. & Tax. Code §17041 and FTB Publication 1031; and the Washington DOR has tightened B&O tax enforcement on Seattle service businesses and out-of-state remote sellers. Acting before the IRS levy hits, the DOR Notice of Determination becomes final, or the FTB issues a Notice of Proposed Assessment is materially easier than reversing any of them after the fact.

What this page covers and why Seattle-specific tax representation matters
Victory Tax Lawyers, LLP is a California-licensed tax-law firm whose primary practice is federal IRS resolution. We represent Seattle individuals, founders, executives, and businesses before the Internal Revenue Service, the U.S. Tax Court, and the IRS Independent Office of Appeals through a Form 2848 Power of Attorney, which is recognized in every IRS district nationwide. Federal tax practice is not constrained by state-bar admission; under 31 CFR §10.3 (Circular 230), attorneys, CPAs, and enrolled agents may represent taxpayers before the IRS regardless of the taxpayer's state of residence.
Seattle tax practice has a specific shape. Washington has no personal income tax — it is one of seven states without a state PIT. Most individual-side federal enforcement comes from the IRS rather than a state department of revenue. But the absence of a state PIT does not mean Washington tax is simple. Three structural features matter on every Seattle case: the new 7% state Capital Gains Tax on long-term gains above an inflation-adjusted threshold ($262,000 for 2026), codified at RCW 82.87 and upheld as constitutional in Quinn v. State, 196 Wn.2d 410 (2023); the Business & Occupation tax under RCW 82.04 — a gross-receipts tax on every Washington business activity that operates on a fundamentally different axis from federal income tax (no deduction for COGS or business expenses); and the state Estate Tax under RCW 83.100, which kicks in at a $2.193 million exemption — roughly one-sixth of the federal threshold — meaning many Seattle estates owe state tax even when no federal tax is due.
Where Seattle diverges from the rest of Washington is the density of equity compensation, the volume of recent California transplants still inside the four-year FTB residency-audit window, and the cluster of Amazon, Microsoft, Starbucks, T-Mobile, Boeing, Costco, Expedia, Zillow, F5, Tableau, Nordstrom, and REI employees whose Form W-2 Box 12 V codes and 1099-B brokerage events generate audit-bait reconciliations at a density that resembles a Bay Area page more than a typical Pacific Northwest page. If your problem is federal, you do not need an attorney admitted in Washington. You need an attorney with active U.S. Tax Court bar membership and federal-practitioner credentials under Circular 230. If your problem also involves the California FTB chasing equity across the state line after a relocation, the firm's California-bar credential is materially useful — we appear in front of the same state revenue agency every week.
Your tax rights as a Seattle taxpayer
Federal taxpayer rights are codified across the Internal Revenue Code and summarized in IRS Publication 1, the Taxpayer Bill of Rights. They apply identically whether you live in Capitol Hill, Ballard, Queen Anne, West Seattle, Fremont, the International District, Beacon Hill, Rainier Valley, Bellevue, Redmond, or Kirkland. The rights you can invoke in a tax-resolution matter:
Right to representation
Under IRC §7521(b)(2), an IRS examiner or collection officer must suspend an interview if you state you wish to consult with an authorized representative. A signed Form 2848 puts a tax attorney between you and the IRS for the remainder of the matter; the agency redirects all future correspondence through the CAF.
Right to Collection Due Process
After a Notice of Federal Tax Lien (IRC §6320) or a Final Notice of Intent to Levy (IRC §6330), you have 30 days to request a Collection Due Process hearing on Form 12153. CDP requests pause collection enforcement and preserve U.S. Tax Court review of any adverse Appeals determination.
Right to U.S. Tax Court review
A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Filing a petition in Tax Court means you litigate without paying the deficiency first. Miss the 90 days and your only remedy becomes pay-then-sue in the U.S. District Court for the Western District of Washington or the U.S. Court of Federal Claims.
Right to an Offer in Compromise
Under IRC §7122, the IRS may accept less than the full liability where doubt as to collectibility, doubt as to liability, or effective tax administration justifies settlement. The offer is filed on Form 656 with Form 433-A(OIC) or 433-B(OIC) financial disclosure attached.
Right to a Collection Statute
IRC §6502 generally gives the IRS 10 years from the date of assessment to collect, after which the debt becomes uncollectible. Several events toll the period: pending OICs, bankruptcy, CDP hearings, and military deployment. Pull your IRS Account Transcripts to verify your Collection Statute Expiration Date before negotiating anything.
Washington-specific: state assessment and appeal rights
For matters at the Washington Department of Revenue, RCW 82.32.050 generally limits assessment of state excise taxes to four years after the close of the tax year, extended for fraud or unfiled returns. A DOR Notice of Determination may be appealed within 30 days to the Washington Board of Tax Appeals under RCW Chapter 82.03. Washington has no state personal income tax, so there is no individual-side state PIT collection-statute clock — but B&O and the new Capital Gains Tax both have their own statute periods.
How Victory Tax Lawyers helps Seattle taxpayers
Offer in Compromise
We prepare and file Form 656 with the supporting financials under IRC §7122. The IRS evaluates Reasonable Collection Potential (RCP) using your monthly income net of allowable expenses plus the realizable value of assets. Seattle filings often turn on the equity-stake question — vested RSU positions in Amazon, Microsoft, T-Mobile, and Expedia, plus pre-IPO ISO holdings in earlier-stage Seattle and Bellevue tech employers, sit awkwardly in RCP analysis. We pressure-test the math before submission so the offer survives at Appeals if intake rejects it.
Installment Agreement
Streamlined IAs (under $50,000), Non-Streamlined IAs over $50,000 with Form 433-F disclosure, and Partial Pay Installment Agreements under IRC §6159 that run only through the CSED. We pick the structure that fits the facts and the runway, not the structure the IRS Automated Collection System proposes by default.
Lien release and withdrawal
A Notice of Federal Tax Lien under IRC §6321 attaches to your Seattle real estate, brokerage accounts, and personal property. We pursue release after payment, certificate of discharge for specific property (often needed to close a King County home sale), subordination to allow refinancing, and withdrawal under the Fresh Start lien-withdrawal program for IAs of $25,000 or less.
Levy release
Wage levies (CP90 / LT11 series) and bank levies under IRC §6331 stop when we secure CNC status, an accepted IA, an accepted OIC, or a CDP request. Time matters: bank levies hold for 21 days before remittance under IRC §6332(c). Brokerage levies on Seattle tech-equity accounts can be devastating if not released before liquidation, particularly on highly-concentrated Amazon or Microsoft positions.
Audit and exam defense
Correspondence audits, office exams at the IRS TAC at 915 2nd Avenue in the Federal Office Building downtown, and field audits. We respond to Information Document Requests, attend the audit in your place under Form 2848, prepare the Form 4549 protest if we disagree, and take the case to the IRS Independent Office of Appeals if the examiner will not move.
Penalty abatement
First-Time Penalty Abatement administrative relief and Reasonable Cause requests under IRC §6651 and §6662. Common reasonable-cause arguments for Seattle filers include the 2020-2022 pandemic disruption, serious illness, broker-statement errors on equity reporting, preparer reliance subject to the United States v. Boyle limits, and good-faith reliance on guidance during the rollout year of the WA Capital Gains Tax.
Twelve types of Seattle tax issues we handle
Federal IRS practice areas, with Seattle-specific framing where it matters.
Amazon and Microsoft RSU audits
Amazon stock-comp packages frequently run $200,000 to $500,000 at the cliff-vest mark; Microsoft on-hire grants and refresh tranches sit in the same range. The IRS reconciles Form W-2 Box 12 V codes against broker 1099-B basis and Schedule D. Double-counted basis on RSU sales is the single most common Seattle audit trigger.
ISO exercise and AMT exposure
An incentive stock option exercise creates an Alternative Minimum Tax preference under IRC §55 and the qualification rules of §422. Many Seattle-area engineers exercise-and-hold at pre-IPO Bellevue and Kirkland startups, then face AMT on phantom income with §6662(b)(1) accuracy-penalty exposure on miscalculations.
California departing-resident audits
The California FTB pursues former residents under Cal. Rev. & Tax. Code §17041 and Publication 1031's nine-factor residency test for income sourced to California even after the Seattle move — vested equity, deferred comp, severance, and RSU tranches earned during California service. Post-2020 Amazon and Bellevue Eastside transplants from the Bay Area are heavily targeted.
WA Capital Gains Tax (RCW 82.87)
Washington's 7% Capital Gains Tax on long-term gains above $262,000 (2026 indexed threshold) is novel. The DOR is in its third cycle of compliance review. We address sourcing disputes, the real-estate exclusion under RCW 82.87.050(2), QSBS interaction under IRC §1202, and federal coordination on the same gain.
B&O tax disputes
B&O under RCW 82.04 is a gross-receipts tax (0.471% retailing, 1.5% services, 1.75% royalties/services) with no deduction for COGS or business expenses. Seattle service businesses frequently misclassify activity between Retailing, Service & Other, and Wholesaling categories, generating multi-year DOR assessments.
IRS audit defense
Correspondence, office, and field audits. We respond, document, and protest examination changes through the IRS Independent Office of Appeals or U.S. Tax Court in Seattle.
Trust Fund Recovery Penalty
Under IRC §6672, the IRS pierces the corporate veil for unpaid payroll trust funds. Seattle SaaS LLC owners frequently discover this after a venture-backed shutdown wipes the cap table. Washington has no state PIT, but unpaid WA Employment Security Department unemployment-insurance tax and L&I workers'-comp premiums run parallel.
FBAR and offshore disclosure
Seattle's Asian-American community concentration — Vietnamese in Rainier Valley, Chinese in the International District, Filipino in Beacon Hill, Japanese-American historic Chinatown-ID, plus Korean and Indian populations in Bellevue and Redmond — means FinCEN Form 114 and IRS Form 8938 issues recur. Streamlined Filing Compliance Procedures resolve good-faith nondisclosure without the willful penalty.
Real-estate §1031 and §121
King County home prices roughly doubled 2017-2022. Many sellers missed the IRC §1031 identification deadline or misapplied the §121 $250K/$500K primary-residence exclusion to an investment property.
US-Canada cross-border
Vancouver BC sits 140 miles north. Seattle filers with Canadian retirement accounts face IRC §217 moving-expense issues, RRSP and TFSA reporting under Form 8891 (historical) and current Rev. Proc. 2014-55 guidance, and US-Canada Tax Treaty Article XVIII pension coordination.
Cannabis §280E disallowance
Washington legalized cannabis under Initiative 502 and RCW Chapter 69.50. Federally, IRC §280E still disallows business deductions other than COGS, generating massive federal income-tax exposure for retail dispensaries even when state-side operations look profitable.
U.S. Tax Court petitions
Deficiency petitions filed in the Tax Court within 90 days of the Notice of Deficiency, with Seattle trial sessions at the Tom Lantos U.S. Courthouse, 700 Stewart Street, Seattle WA 98101.
Nine common causes of tax debt in Seattle
1. Amazon/Microsoft RSU vest withholding gap
Employer-default 22% supplemental withholding on a six- or seven-figure RSU vest understates the true marginal rate. The April balance hits as a surprise when the W-2 lands and the broker 1099-B reconciles against Schedule D.
2. ISO exercise plus AMT trap
An ISO exercise creates an AMT preference under IRC §55. Many Bellevue and Kirkland startup engineers exercise and hold, then watch the stock fall before sale and still owe AMT on phantom income. The IRC §53 credit recovers slowly; the cash-flow squeeze in the exercise year is immediate.
3. California exit illusion
A tech worker moves to Seattle in 2023 thinking the California tax bill is gone. The FTB issues a residency audit in 2026 claiming partial-year residency and California-source RSU income that vested before the move under FTB Pub 1031's nine-factor test.
4. Missed WA Capital Gains Tax filing
First-cycle nonfilers under RCW 82.87 are now drawing DOR Notices of Determination. Many Seattle taxpayers assumed the tax did not survive constitutional challenge and skipped the first-year filing; Quinn v. State (2023) closed that argument.
5. Sold a King County home without §1031
King County saw aggressive 2017-2022 appreciation. Investment-property sales without a like-kind exchange under IRC §1031 triggered surprise federal capital-gains balances, and the §121 exclusion does not save an investment property.
6. Self-employment quarterly miss
Seattle's freelance design, music, film, and software-consulting workforce often skips quarterly estimates under IRC §6654. The 15.3% self-employment tax under §1401 compounds the federal income-tax balance, then B&O on the same gross receipts runs on top.
7. Startup payroll lapse
A Seattle SaaS LLC stops depositing 941 trust funds during a fundraise gap. The IRS asserts TFRP against the founders personally under IRC §6672. The state side becomes a WA Employment Security Department unemployment-insurance case plus L&I workers'-comp exposure.
8. ERC clawback
Employee Retention Credit claims pushed by promoter mills are being clawed back through CP207/CP207L letters. Seattle restaurants, dental practices, music venues, biotech consultancies, and SaaS shops face the audit wave.
9. Crypto and DeFi gaps
Exchange 1099-K and 1099-MISC reports do not match the taxpayer's Schedule D. The IRS Automated Underreporter program issues a CP2000 notice for the gap, often with a six-figure proposed deficiency. Form 1099-DA arrives in 2026 under the new broker-reporting regime.
Who is on the hook: eight tax-liability scenarios
Joint filers and community property
Washington is a community-property state under RCW 26.16. Joint federal returns create joint-and-several liability under IRC §6013(d)(3); one spouse can be pursued for the full balance. Community-property allocation analysis applies under Rev. Rul. 56-462 and the federal community-property rules. Innocent Spouse Relief under IRC §6015 is the principal escape valve.
Responsible persons for payroll
Trust Fund Recovery Penalty under IRC §6672 reaches anyone with check-signing authority who willfully failed to pay over withheld taxes — not just CEOs. For Seattle startups, this often catches the head of finance or office manager along with the founder.
WA B&O responsible-party liability
Unpaid B&O and sales tax can attach to corporate officers and members under RCW 82.32.145 for collected-but-unremitted retail sales tax. The DOR pursues these as personal-liability assessments after entity dissolution.
Transferee liability
IRC §6901 reaches a transferee of assets where the transfer rendered the transferor insolvent and tax debts remain unpaid. Seattle family-LLC restructurings and Mercer Island estate transfers sometimes trigger this.
California source-of-income claims
Under Cal. Rev. & Tax. Code §17041 and the FTB's Publication 1031 sourcing rules, equity that vested while the taxpayer rendered services in California remains California-source on sale — even years after the Seattle move. The FTB pursues these as nonresident-source claims well after the relocation looks "clean."
Nominee and alter-ego
The IRS files a nominee or alter-ego lien when assets titled in another's name actually belong to the taxpayer. Common in Seattle asset-protection structures using family-LLC arrangements and Washington-state asset-protection trusts.
WA Estate Tax exposure
Under RCW 83.100, the Washington Estate Tax kicks in at a $2.193M exemption — far below the federal $13.6M threshold. Many Seattle homeowners with appreciated King County real estate, concentrated tech equity, and retirement accounts cross the WA threshold without owing federal estate tax. The personal representative is liable for filing and payment.
Estate and decedent returns
A decedent's final 1040, the estate's 1041, the federal 706 (if applicable), and the WA Estate Tax return run together. Personal liability for the executor attaches under 31 USC §3713(b) if estate distributions are made before federal tax claims are satisfied.
What resolution can look like
Debt reduced
An accepted Offer in Compromise settles the federal liability for less than the full amount. Partial Pay IAs cap the recovery at what you can pay through the CSED. Currently Not Collectible status freezes collection while a founder rebuilds runway.
Penalties abated
First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests address pandemic disruption, serious illness, and broker-statement reporting errors on RSU and ISO transactions.
Liens and levies released
An NFTL withdraws once a streamlined IA is in place under Fresh Start. Wage and bank levies release when the underlying account moves to CNC, IA, or OIC processing. Passport certifications reverse once the debt drops below the §7345 threshold.
Outcomes vary. Past results do not guarantee future outcomes. Each tax case is unique.
Settlement ranges from the firm's case files
The following ranges come from Victory Tax Lawyers cases over the past several years and contribute to the firm's $100M+ aggregate tax-relief figure. Names and identifying facts are removed for confidentiality.
| Matter type | Original liability | Resolution | Approximate result |
|---|---|---|---|
| Installment Agreement | $138,296 | IRC §6159 streamlined IA | $25/month accepted |
| Partial Pay IA | $126,489 | IRC §6159 PPIA through CSED | $50/month accepted |
| Installment Agreement | $128,206 | IRC §6159 streamlined IA | $25/month accepted |
| Partial Pay IA | $116,451 | IRC §6159 PPIA through CSED | $50/month accepted |
| Installment Agreement | $152,296 | IRC §6159 streamlined IA | $25/month accepted |
Past results do not guarantee future outcomes. Each tax case is unique and turns on facts, asset position, monthly disposable income, IRS Allowable Living Expense tables, and the discretion of the assigned Revenue Officer or Settlement Officer. Acceptance rates for Offer in Compromise vary widely — the IRS reported a nationwide acceptance rate of roughly 30 to 40 percent in recent years.
Why a California-licensed firm represents Seattle taxpayers
Federal tax practice is regulated by Treasury under 31 CFR Part 10 (Circular 230). An attorney admitted in any U.S. jurisdiction may represent any taxpayer before the IRS in any state via Form 2848 Power of Attorney. State-bar admission is a state-court question; the IRS is a federal agency, the U.S. Tax Court is a federal court of national jurisdiction, and the IRS Independent Office of Appeals is a federal administrative venue. Whether you live in Capitol Hill, Ballard, Queen Anne, West Seattle, Bellevue, Redmond, or Kirkland, the federal procedural rules are identical.
Parham Khorsandi is a member of the State Bar of California (license #266658) and is admitted to practice before the United States Tax Court — admission there is national, not state-bound. Amir Boroumand (Cal Bar #269570) supplements the firm's federal practice. For Seattle specifically, the California-bar credential is more than a procedural footnote: the FTB's departing-resident audit program reaches former Bay Area residents who relocated to Amazon, Microsoft, T-Mobile, and Expedia roles after 2020, and we appear before the FTB on these matters regularly. Few Washington firms see Cal. Rev. & Tax. Code §17041 source-of-income disputes at any volume.
For Washington Department of Revenue work — B&O assessments, Capital Gains Tax disputes, sales-and-use tax audits, Estate Tax matters — representation runs through a Washington-DOR power of attorney. For litigation that reaches the Washington Board of Tax Appeals on a formal proceeding, or any matter that proceeds to the King County Superior Court on judicial review, we refer to local Washington counsel and stay engaged on the federal side. The 100% remote workflow runs through a secure portal: document upload, signed Forms 2848 and 8821, and weekly status updates without anyone needing to drive downtown.
The seven steps of a VTL tax-resolution engagement
Free consultation
A 30-minute call with an attorney to outline the facts, the IRS, WA DOR, or FTB notices received, and the realistic resolution options.
Engagement letter
A written attorney-client agreement defines scope, fee, and authority. Federal common-law attorney-client privilege attaches from signature forward.
Form 2848 filed
Power of Attorney filed with the IRS Centralized Authorization File so all subsequent IRS notices route to the firm. WA DOR power filed where state matters overlap.
CAF investigation
Account Transcripts, Wage and Income Transcripts, and Record of Account pulled across all open years. CSED dates verified before any negotiation.
Strategy memo
A written analysis recommending OIC, IA, CNC, audit response, CDP, or Tax Court petition based on the financial profile and CSED runway.
Resolution filed
Forms 656, 433-A, 9423, 12153, or Tax Court Petition prepared and filed. Negotiations with Revenue Officers, Settlement Officers, or Appeals Officers handled directly.
Compliance close-out
Post-resolution monitoring: future quarterly estimates, return filings, B&O compliance, and protection against IA default. The case closes when the new pattern is stable.
Collection statute warning — federal, Washington, and California
Under IRC §6502(a), the IRS generally has ten years from the date of assessment to collect a tax. After the Collection Statute Expiration Date, the debt becomes uncollectible by operation of law. Several events toll the CSED, including a pending Offer in Compromise (extends by the OIC pendency plus 30 days), bankruptcy filing (extends by the bankruptcy stay plus six months), a Collection Due Process hearing (extends while pending), Innocent Spouse claims, and continuous absence from the United States for six months or more.
On the Washington side, RCW 82.32.050 generally limits the DOR to four years after the close of the tax year for assessment of B&O, sales-and-use, and other excise taxes, with longer periods for fraud or unfiled returns. The new Capital Gains Tax follows its own statute under RCW Chapter 82.87. Washington has no state personal income tax, so there is no individual-side state PIT collection clock to track — but B&O for sole proprietors, the Capital Gains Tax for high-earner sales, and the Estate Tax for decedents all run separately.
On the California side — the third leg that matters for Seattle transplants from the Bay Area — the FTB has a 20-year statute of limitations on collection of California income tax under Cal. Gov. Code §7172 after entry of the assessment, and a four-year statute of limitations on assessment under Cal. Rev. & Tax. Code §19057 (extended to six years for substantial omissions and unlimited for unfiled returns). The FTB collection horizon is twice the federal one. Pull every account transcript before negotiating anything; sometimes a Partial Pay Installment Agreement that runs out the federal statute is the better strategy than an offer that extends it.
Seattle venue: where federal and Washington tax matters are heard
Federal tax matters affecting Seattle taxpayers proceed in federal venues. State matters that reach formal contest proceed through the Washington Department of Revenue and on appeal through the independent Washington Board of Tax Appeals in Olympia — with judicial review available in King County Superior Court.
U.S. Tax Court — Seattle trial sessions
The United States Tax Court hears Seattle cases at the Tom Lantos U.S. Courthouse, 700 Stewart Street, Seattle WA 98101. Trial sessions are scheduled on rotation throughout the year; petitioners designate Seattle as the place of trial under Tax Court Rule 140.
U.S. District Court — Western District of Washington, Seattle Division
The U.S. District Court for the Western District of Washington, Seattle Division sits at 700 Stewart Street, Seattle WA 98101. Federal refund suits under IRC §7422 and criminal-tax matters proceed there.
IRS Taxpayer Assistance Center — Seattle
The IRS operates a TAC at the Federal Office Building, 915 2nd Avenue, Seattle WA 98174. Appointments are scheduled through the IRS office locator or 844-545-5640.
Washington Department of Revenue
The Washington Department of Revenue is headquartered at 1101 S Eastside Street Suite 1, Olympia WA 98501, with a Seattle field office at 2101 4th Avenue Suite 1400, Seattle WA 98121. The DOR administers B&O, sales-and-use, the new Capital Gains Tax, and the state Estate Tax.
Washington Board of Tax Appeals
The Washington Board of Tax Appeals at 1110 Capitol Way S Suite 105, Olympia WA 98504, is the independent state administrative tribunal that hears state-tax appeals from DOR Notices of Determination under RCW Chapter 82.03. Judicial review proceeds to superior court.
King County Treasury and Assessor
The King County Treasury and the King County Assessor share offices at 500 4th Avenue Suite 600, Seattle WA 98104. They handle property-tax assessment and collection. Property-tax appeals run through the King County Board of Equalization.
City of Seattle — Finance and Administrative Services
The City of Seattle Department of Finance and Administrative Services at 700 5th Avenue Suite 4250, Seattle WA 98104, administers the city's business license tax, payroll expense tax (JumpStart), and short-term rental compliance separately from the state DOR.
WA Employment Security Department
The Washington Employment Security Department administers state unemployment-insurance tax and Paid Family & Medical Leave premiums for Seattle employers. The WA Department of Labor & Industries administers workers'-comp premiums. Federal payroll tax (FICA, FUTA, withholding) is enforced by the IRS separately.
Request a free consultation with a Seattle-focused tax attorney
A 30-minute call with an attorney costs nothing. Bring your most recent IRS notice, your last filed return, any WA DOR Notice of Determination, and any California FTB notice if you relocated from California. We will tell you which resolution options actually fit your facts before you sign anything.
