Tax Attorney in Oregon
Federal IRS representation for Oregon taxpayers — audits, back taxes, liens, levies, Offer in Compromise filings, and U.S. Tax Court petitions. Oregon stacks a graduated personal income tax (4.75% to 9.9%), a corporate income tax (6.6% to 7.6%), and the Corporate Activity Tax (CAT) on gross receipts — one of the heavier state-tax structures in the country, despite having no general sales tax. Our team handles the federal side and coordinates with Oregon counsel where state matters reach the Oregon Tax Court.

If you owe back taxes in Oregon, here is what shifted in 2026
The IRS resumed full passport-revocation referrals under IRC §7345 for taxpayers with seriously delinquent federal tax debts above the inflation-adjusted threshold (currently $62,000 for 2026). The Oregon Department of Revenue also accelerated Corporate Activity Tax (CAT) enforcement on the 0.57% gross-receipts surcharge that hits Oregon businesses with more than $1 million in commercial activity — an audit cycle that has produced multiple appeals through the Oregon Tax Court since 2022. On the federal side, the IRS expanded automated bank-account levies under IRC §6331 with a 21-day hold before funds are released. Acting before the levy hits is materially easier than reversing it after.

What this page covers and why state-specific representation matters in Oregon
Victory Tax Lawyers, LLP is a California-licensed tax-law firm whose primary practice is federal IRS resolution. We represent Oregon individuals 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.
Oregon tax practice has a particular shape. The state imposes a graduated personal income tax (4.75% to 9.9% at the top bracket) administered by the Oregon Department of Revenue under ORS Chapter 316. Oregon corporations pay a 6.6% to 7.6% corporate income tax under ORS Chapter 317, plus a Corporate Activity Tax (CAT) of 0.57% on Oregon-sourced commercial activity above $1 million under ORS Chapter 317A. Oregon is one of five states with no general sales tax, which shifts the entire collection burden onto income and gross-receipts taxes. Multnomah County and the Portland Metro area stack additional local income taxes — the Preschool for All tax, the Metro Supportive Housing Services tax, and the Portland Arts Tax — on top of state and federal liabilities.
If your problem is federal, you do not need an attorney admitted in Oregon. You need an attorney admitted somewhere with active U.S. Tax Court bar membership and federal-practitioner credentials under Circular 230. For state matters that reach litigation, the Oregon Tax Court is the dedicated tribunal — we work with Oregon counsel on those filings while staying engaged on the federal posture.
Your tax rights as an Oregon 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 to a resident of Portland, Bend, Medford, or Coos Bay. Oregon adds its own taxpayer-rights provisions under ORS Chapter 305. The major 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 your tax attorney between you and the IRS for the remainder of the matter. Oregon Department of Revenue interviews carry parallel rights under ORS 305.230.
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 federal collection and preserve U.S. Tax Court review.
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 can litigate without paying the deficiency first. Miss the 90 days and your only remedy becomes pay-then-sue in District Court 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. Oregon has a parallel state-level settlement-offer program for state liabilities.
Right to a Collection Statute
IRC §6502 generally gives the IRS 10 years from the date of assessment to collect, after which the federal 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.
Oregon-specific: Tax Court appeal rights
Under ORS Chapter 305, a taxpayer who disputes a state assessment may appeal first to the Magistrate Division of the Oregon Tax Court, then to the Regular Division if the magistrate decision is adverse. Oregon is one of the few states with a dedicated, specialized tax court rather than a general-jurisdiction tribunal.
How Victory Tax Lawyers helps Oregon 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. We pressure-test the math before submission so the offer reaches Appeals if rejected at intake. Oregon's parallel settlement-offer program for state liabilities is filed separately with the Oregon Department of Revenue.
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 your facts and your runway. Oregon DOR payment plans run on a parallel track for state balances.
Lien release and withdrawal
A Notice of Federal Tax Lien under IRC §6321 attaches to your Oregon real and personal property and is recorded with the county recorder and the Oregon Secretary of State UCC database. We pursue release after payment, certificate of discharge for specific property, 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). Oregon DOR garnishments operate under ORS 18.700 and run separately from federal levies.
Audit and exam defense
Correspondence audits, office exams, 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 with proposed adjustments, and take the case to the IRS Independent Office of Appeals if needed. Oregon DOR audits run on parallel timelines under ORS Chapter 314.
Penalty abatement
First-Time Penalty Abatement administrative relief and Reasonable Cause requests under IRC §6651. Common reasonable-cause arguments for Oregon filers include the 2020 Labor Day fires, 2024 Cascadia winter-storm disaster declarations, serious illness, and reliance on a preparer (subject to Boyle limits).
12 types of Oregon tax issues we handle
Federal IRS practice areas, with Oregon-specific framing where relevant.
Unfiled federal and state returns
Oregon filers must reconcile Form 1040 with Form OR-40 each year. We reconstruct prior years using IRS Wage and Income transcripts, then work with the Oregon Department of Revenue for state-side compliance.
IRS audit defense
Correspondence, office, and field audits out of the Portland and Salem IRS offices. We respond, document, and protest examination changes through Appeals or U.S. Tax Court.
Trust Fund Recovery Penalty
Under IRC §6672, the IRS can pierce the corporate veil for unpaid payroll trust funds. Oregon LLC and S-corp owners often discover this after a business shutters and the entity dissolves.
Wage and bank levies
CP90 / LT11 final notices, bank account levies on Umpqua Bank, KeyBank, and U.S. Bank accounts, and accounts-receivable levies for Oregon business owners.
Federal tax liens on Oregon property
NFTLs recorded with the Oregon Secretary of State UCC database and county recorder cloud title on homes, timberland, vineyards, and commercial property across the state.
Passport revocation defense
IRC §7345 certifications to the State Department. We work to decertify before travel for Portland-area tech contractors, Intel international engineers, and cross-border professionals working in British Columbia or Asia.
Offer in Compromise filings
Doubt as to Collectibility OICs for Oregon filers with limited equity, often paired with Currently Not Collectible status during processing. Oregon settlement-offer applications run on a parallel track.
Innocent Spouse Relief
Form 8857 relief under IRC §6015. Oregon is an equitable-distribution state for divorce, but joint federal returns still create joint-and-several federal liability.
Corporate Activity Tax (CAT) appeals
The CAT under ORS Chapter 317A imposes 0.57% on Oregon-sourced commercial activity above $1 million. Apportionment, exclusions for groceries and motor fuel, and unitary-group questions have driven significant Oregon Tax Court litigation since 2020.
U.S. Tax Court petitions
Deficiency petitions filed in the Tax Court within 90 days of the Notice of Deficiency, with trial sessions in Portland. Petitioners outside the Portland metro often designate Seattle as an alternate venue.
Self-employment back taxes
Oregon has a high concentration of 1099 contractors — tech consultants, vineyard labor brokers, gig-economy drivers around Portland and Eugene. Unpaid SE tax under IRC §1401 compounds quickly with state-tax stacking.
Cryptocurrency reporting issues
Portland and the broader Silicon Forest corridor are crypto-active metros. We address unreported gains, Form 1099-DA exposure, and John Doe summons defense for taxpayers with Coinbase, Kraken, and decentralized-exchange activity.
Nine common causes of tax debt in Oregon
1. Stacked Portland Metro local income taxes
Portland residents and high earners in Multnomah County face the Metro Supportive Housing Services tax (1% on income above $125,000 single / $200,000 joint) plus the Multnomah County Preschool for All tax (an additional 1.5% to 3% on the same income brackets). Filers who relocate or whose withholding does not capture these local taxes often owe several thousand dollars at filing.
2. Small business payroll lapses
An Oregon LLC stops depositing 941 trust funds during a slow quarter. The IRS asserts TFRP against the owner personally under IRC §6672. The state side becomes an Oregon Employment Department unemployment-insurance collection.
3. Unfiled returns after divorce
Years of unfiled returns trigger substitute-for-return assessments under IRC §6020(b). Oregon DOR mirrors federal SFRs through its data-share agreement and assesses state tax based on the federal substitute return.
4. Sold real estate without 1031
Portland, Bend, and the Willamette Valley wine country saw aggressive 2021-2024 real-estate appreciation. Investment-property sales without a like-kind exchange under IRC §1031 triggered surprise capital-gains balances at the 9.9% Oregon top rate.
5. Corporate Activity Tax surprise assessments
Oregon businesses crossing the $1 million commercial-activity threshold first time often miss the CAT quarterly estimates required under ORS 317A.137. The shortfall plus penalties and interest can run six figures for mid-sized distributors and contractors.
6. ERC clawback exposure
Employee Retention Credit claims submitted by promoter mills are being clawed back through CP207/CP207L letters. Many Oregon restaurants, dental practices, and contractors face the audit wave.
7. Crypto trading without records
Portland and Eugene crypto holders received 1099-K and 1099-MISC reports from exchanges. The IRS matches them to filed returns and issues CP2000 notices for the gap. Oregon DOR conforms to federal capital-gains treatment and assesses state tax on the same gap.
8. Wildfire-disrupted filing
Oregon filers affected by the 2020 Labor Day fires (Almeda, Echo Mountain, Beachie Creek complexes) received disaster-zone extensions. Many filers missed the extended deadlines or never reconstructed records lost in the fires, triggering unfiled penalty stacks.
9. Pass-through entity tax confusion
Oregon's elective Pass-Through Entity Elective Tax (PTE-E) under ORS 316.043 lets S-corps and partnerships pay state tax at the entity level to work around the federal SALT cap. Misapplied elections produce double-taxation outcomes and amended-return cycles that surface as unpaid balances.
Who is on the hook: eight tax-liability scenarios
Joint filers
Joint federal returns create joint-and-several liability under IRC §6013(d)(3). One spouse can be pursued for the entire balance. Innocent Spouse Relief under IRC §6015 is the principal escape valve. Oregon mirrors the federal rule under ORS 316.367.
Responsible persons for payroll
Trust Fund Recovery Penalty under IRC §6672 reaches anyone who had check-signing authority and willfully failed to pay over withheld taxes — not just officers.
Oregon CAT responsible persons
Under ORS 317A.131, a person required to file the CAT return who fails to do so may be personally assessed. Officers and managers of unitary groups can be reached for unpaid CAT obligations.
Transferee liability
IRC §6901 reaches a transferee of assets where the transfer rendered the transferor insolvent and tax debts remain unpaid. Oregon family-LLC restructurings and intergenerational vineyard or timber transfers can trigger this.
Successor business under §6324
Asset purchases where the buyer continues the seller's business operations can carry forward IRC §6324 estate-tax liability and analogous successor exposure for income tax. Oregon Department of Revenue requires a bulk-sale tax clearance certificate to break the chain on the state side.
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 Oregon asset-protection structures using rural-property LLCs and Bend or Lake Oswego trust arrangements.
Multnomah County / Portland Metro local taxpayers
Unpaid Multnomah County Preschool for All tax, Metro Supportive Housing Services tax, and Portland Arts Tax stay with the individual filer. The City of Portland Revenue Division administers collection and can assess interest and civil penalties for unfiled or unpaid local returns.
Estate and decedent returns
A decedent's final 1040 and the estate's 1041 are the executor's responsibility. Personal liability for the executor attaches under 31 USC §3713(b) if distributions are made before federal tax claims are satisfied. Oregon imposes a state estate tax under ORS Chapter 118 with a $1 million exemption threshold — well below the federal threshold — so Oregon estates of mid-net-worth decedents file an Oregon Form OR-706 even when no federal Form 706 is required.
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.
Penalties abated
First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests address wildfire-disaster periods, serious illness, and preparer reliance.
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 are reversed 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 Oregon 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.
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 to that court is national, not state-bound. Amir Boroumand (Cal Bar #269570) supplements the firm's federal practice.
For matters that require an attorney admitted in Oregon — for example, an Oregon Tax Court Regular Division appeal or a state-court Corporate Activity Tax constitutional challenge — we coordinate with Oregon counsel and stay engaged on the federal-tax side. Many VTL Oregon cases are pure federal practice and do not require Oregon-bar representation at all.
The seven steps of a VTL tax-resolution engagement
Free consultation
A 30-minute call with an attorney to outline the facts, the IRS 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.
Form 2848 filed
Power of Attorney filed with the IRS Centralized Authorization File so all subsequent IRS notices route to the firm.
CAF investigation
Account Transcripts, Wage and Income Transcripts, and Record of Account pulled across all open tax years. CSED dates verified.
Strategy memo
A written analysis recommending OIC, IA, CNC, audit response, CDP, or Tax Court petition based on the financial profile.
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, and protection against IA default. The case is not done when the offer is accepted; it is done when the new pattern is stable.
Collection statute warning — federal and Oregon
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 or extend 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 Oregon side, ORS Chapter 314 sets a three-year statute of limitations on assessment under ORS 314.410, extended where the taxpayer omits more than 25% of gross income (six years) or files a false return or no return (unlimited). Once a state tax is assessed, the Oregon Department of Revenue's collection authority under ORS 305.895 is not subject to a fixed expiration period in the same way federal CSED operates — the state may continue collection until paid, although practical enforcement priorities and bankruptcy discharge can limit recovery.
Before negotiating any resolution, pull your IRS Account Transcripts and verify your CSED dates. Submitting an OIC restarts an already-running federal clock; sometimes a Partial Pay Installment Agreement that runs out the statute is the better strategy than an offer that extends it.
Oregon venue: where federal and state tax matters are heard
Federal tax matters affecting Oregon taxpayers proceed in federal venues. State matters that reach litigation proceed through the Oregon Department of Revenue conference process and then the Oregon Tax Court, which has two divisions: Magistrate and Regular.
U.S. Tax Court — Oregon trial sessions
The United States Tax Court holds trial sessions in Portland. An Oregon petitioner identifies the preferred place of trial in the petition; the case is generally calendared to the Portland session. Petitioners in eastern or southern Oregon sometimes designate Seattle or Boise as alternates when the calendar is more accommodating.
IRS Taxpayer Assistance Centers
The IRS operates TACs in Portland, Salem, Eugene, Medford, and Bend. Appointments are scheduled through the IRS office locator or 844-545-5640.
Oregon Department of Revenue
The Oregon Department of Revenue administers state personal income tax, corporate income tax, Corporate Activity Tax, and a number of trust-fund obligations. Field offices serve taxpayers in Salem (headquarters), Portland, Eugene, Medford, Bend, Gresham, and Lake Oswego.
Oregon Tax Court — Magistrate Division
The Oregon Tax Court sits in Salem. The Magistrate Division hears most appeals first under an informal procedure; a taxpayer may proceed without an attorney. Decisions may be appealed within 60 days to the Regular Division, where formal rules of evidence apply and Oregon Bar admission is required for counsel.
City of Portland Revenue Division
The City of Portland Revenue Division administers the Multnomah County Preschool for All tax, the Metro Supportive Housing Services tax, the Portland Arts Tax, and the City of Portland Business License Tax / Multnomah County Business Income Tax. Local-tax disputes are heard administratively before reaching the Oregon Tax Court.
Federal District Courts
Oregon is a single federal judicial district — the District of Oregon — with courthouse locations in Portland, Eugene, Medford, and Pendleton. Refund suits and criminal-tax cases proceed in the relevant division. Major Oregon cities served include Portland, Salem, Eugene, Gresham, Hillsboro, Beaverton, Bend, Medford, Springfield, and Corvallis.
Request a free consultation with an Oregon tax attorney
A 30-minute call with an attorney costs nothing. Bring your most recent IRS notice, your last filed return, and any state correspondence from the Oregon Department of Revenue or City of Portland Revenue Division. We will tell you which resolution options actually fit your facts before you sign anything.
