Best CPA Firm in Portland OR for Tax Specialists and Accounting

Your Trusted Tax Specialist

Most Portland business owners and individuals pay more in taxes than they should. Not because Oregon’s tax system is impossible to navigate, but because they do not have a trusted tax advisor in Portland actively working to reduce what they owe. That is exactly what Dimov Tax is here to fix. We are a Portland CPA firm and tax specialist built around one goal: keeping more money in your pocket. Our tax accountants know Oregon tax law inside and out, understand the Portland market, and build strategies around your specific situation, not a generic template pulled from a shelf. Whether you need a Portland tax advisor to guide your long-term planning, a tax accountant to handle your annual filings, or a full-service CPA firm to manage your business accounting and bookkeeping, Dimov Tax covers every piece of the puzzle. We work with small business owners, independent contractors, and individuals across Portland and Oregon who are done guessing and ready for real financial results.

"Dimov was great - helped me recuperate taxes for a repaid bonus that I would not have been able to navigate on my own. I had to submit follow up documents and they confidently prepared the form and walked me through what was needed, which ultimately resulted in successful refund. Definitely recommend / would use Dimov again. They were quick with communication when I came to them on short notice, handling everything very professionally." - Kirstin

Individual Portland Filers: Metro SHS, RSUs and Part-Year Residency

Portland individual filers rarely deal with just the Oregon DOR return. The city and county add surcharge exposure most preparers don’t calculate, RSU sourcing that doesn’t reset when you move, and part-year residency positions the Oregon DOR audits more closely than most filers expect. The clients we see most often here: RSUs vested during Oregon residency Metro SHS exposure that surprises high earners Part-year residency claims the Oregon DOR does not accept without scrutiny

Portland Business License Tax Plus Multnomah and Metro Filing

Most Portland operators register with the Revenue Division for the Business License Tax at 2.6% and assume the obligation ends there. It does not. Three separate layers apply: Business License Tax: 2.6%, filed with the Portland Revenue Division Multnomah County Business Income Tax: 2%, with its own registration requirement and deadline calendar Metro SHS: 1%, under a separate jurisdiction entirely, triggered when total gross receipts exceed $5 million Qualifying for an exemption from any of these still requires a filed return with supporting tax pages attached. As a CPA in Portland, we cover all three alongside the Oregon DOR return for tech companies, manufacturers, and food producers operating anywhere inside city and county lines.

Tax Preparation in Portland for RSUs, Residency, and Metro Surcharges

Oregon taxes residents on income from all sources вЂ” and RSUs that vested during your Oregon residency stay taxable here even after you relocate to Washington. Two surcharges apply on top of the state return: Metro SHS: 1% above $128,000 for single filers in 2026 Multnomah County Preschool for All: 1.5% starting at $125,000, with a second tier above $250,000 This affects more filers than most expect: Tech employees with large vesting schedules Athletic industry executives who moved mid-year Part-year residents who assumed filing Oregon was behind them Oregon-specific additions and modifications mean the state return never simply imports from the federal one.

Do Portland businesses with a BLT exemption still need to file?

Yes, a Portland business that qualifies for a Business License Tax exemption still must file a return. Exemption removes the liability, not the filing requirement. The Revenue Division expects a return with supporting tax pages regardless. Skipping it generates a penalty on its own track. We file in every case.

Does Oregon tax RSUs after I relocated to Washington?

Oregon likely does. The state sources equity to where the work occurred during the vesting period, not your address at settlement. Relocation does not reset the sourcing. Our CPA in Portland calculates the Oregon-source fraction before the return goes out.

What happens to Portland tax obligations when gross receipts cross $5 million?

A third obligation appears: Metro SHS Business Income Tax at 1%, under Metro jurisdiction, separate from both the Portland Business License Tax and the Multnomah County return. Three filings now run on independent tracks. None of them prompts you about the others. Separate books for each jurisdiction are not optional. Our bookkeeping services in Portland build that structure before the first return goes out.

How much does Multnomah County Tax add on top of the Oregon return?

Two surcharges apply, neither on the Oregon return. Multnomah County PFA starts at 1.5% above $125,000, with a second tier at $250,000. Metro SHS adds 1% above $128,000 for single filers in 2026. Both run through the City of Portland Revenue Division.

How does the Portland BLT treat S-Corp salaries vs pass-through distributions?

The tax applies to net income. Reasonable salary reduces the entity’s taxable base, then hits the owner’s personal return, where Metro SHS or PFA thresholds may apply. A dedicated accountant in Portland working across both entity and personal returns reviews them together. Errors at one level surface at the other.

My experience was superb! They communicated well and did an exemplary job on preparing my taxes for multiple years and prepared k-1s for my business partners. I’m grateful to have stumbled upon them after having to close my business. They were also very reasonably priced compared to other quotes I received.
