Which tax jurisdictions Hillsboro is actually in
Hillsboro 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.
- Inside the TriMet district, so the TriMet self-employment tax reaches self-employed people working here — see transit taxes.
- High incomes mean most Hillsboro professional households are above the Metro SHS threshold, often without adequate withholding.
The local economy, and what it means for a tax return
Semiconductor and advanced manufacturing employment dominates, with a supporting professional and contractor base. Equity compensation — RSUs, ESPP and options — is the recurring theme, along with the international questions that come with a globally mobile workforce.
We work with clients around the Sunset Corridor and Ronler Acres, downtown Hillsboro, Orenco Station and the agricultural land west toward Cornelius.

What we do most of in Hillsboro
Tax situations we see in Hillsboro
Foreign accounts have a lower threshold than people expect
A globally mobile workforce brings reporting obligations that have nothing to do with owing tax. Foreign bank and investment accounts above a modest aggregate balance require an annual report, and certain foreign assets require a further form with the return. The penalties are assessed per account and per year regardless of whether any tax was due. It is paperwork rather than liability, and it is the thing most commonly missed on an otherwise well-prepared Hillsboro return.
Working with us from here
About forty minutes from the Clackamas office. Most Hillsboro clients work with us remotely.
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 Hillsboro
Is my ESPP cost basis on the 1099-B correct?
Frequently not. Brokers commonly report the discounted purchase price without the discount that was already included in your W-2 wages. Filing as reported means paying tax twice.
I moved here from another country mid-year.
Residency for tax purposes, treaty positions and foreign account reporting all come into play. Bring the details rather than guessing.
Do I owe Metro SHS?
Hillsboro is inside the Metro district, so yes on income above the threshold — which most professional households here clear.
I still have accounts in my home country. Do I have to report them?
Very likely, once the combined balance crosses the threshold at any point in the year — even if the accounts earn nothing and no US tax is owed. Bring the details; the reporting is routine and the penalties for skipping it are not.
