Washington County

Tax preparation and bookkeeping in Beaverton, OR

Beaverton combines a large corporate employment base with one of the most diverse small-business communities in the metro, and the two produce very different tax needs from the same postcode.

Which tax jurisdictions Beaverton is actually in

Beaverton is in Washington County. Oregon’s local tax boundaries do not follow city limits or ZIP codes, so this is worth being precise about.

  • Inside the Metro district, so Metro SHS applies to income above $128,000 single / $205,000 joint.
  • Outside Multnomah County, so Preschool for All does not apply on residency — but it can still apply to income sourced to work performed in the county.
  • Not in the City of Portland — no Arts Tax.
  • A Beaverton business serving Portland clients can still owe Portland Business License Tax on the apportioned share.
  • Inside the TriMet district, so the TriMet self-employment tax reaches self-employed people working here — see transit taxes.

The local economy, and what it means for a tax return

Major corporate employers on the west side, a dense professional services layer, and a substantial community of immigrant-owned small businesses in retail, food service and personal services — many of which are first-generation and have never had a bookkeeper.

We work with clients around the Beaverton Central and downtown area, the Highway 217 corridor, the corporate campuses to the west and Cedar Hills and Raleigh Hills.

Who we work with in Beaverton

  • Corporate employees with restricted stock, ESPP and option exercises
  • Family-run food, retail and personal service businesses, many of them first-generation
  • Professional consultancies serving clients across the metro
  • Households navigating a first year of US filing after relocating internationally

What we do most of in Beaverton

Tax situations we see in Beaverton

A first business meets four registrations at once

Opening a business in Beaverton means Oregon registration, an EIN, payroll accounts on the first hire, and — if any of the work is delivered to Portland customers — city and county business registration as well. Each one is straightforward on its own. Discovering all four in the third year, with penalties attached, is not, and it is the most common pattern we clean up in this city.

Working with us from here

About thirty minutes from the Clackamas office, or fully remote — most Beaverton clients prefer remote.

Most clients outside the immediate Clackamas area work with us remotely — secure document exchange, a phone or video appointment, and e-filing. If you would rather sit across a desk, both offices do that too: Clackamas and The Dalles.

Questions we get from Beaverton

I have RSUs from a west-side employer. Anything specific?

Yes — vesting is ordinary income, the sale is a separate capital transaction, and the cost basis reported by brokers is frequently wrong in a way that causes double taxation if not corrected.

I am opening my first business. What do I need to register for?

Depends on the activity, but commonly: Oregon business registration, payroll accounts if you hire, city business registration where you operate, and CAT registration if receipts grow.

Do I owe Preschool for All?

Not on residency — Beaverton is Washington County.

We speak Spanish at home. Can we work with you?

Tell us when you call and we will make sure the engagement works for you, including how documents and explanations are handled. It matters more on a tax return than on most things.
