CPA and tax preparation in Sherwood

Sherwood CPA help for Washington County households

Sherwood is in Washington County, with City Hall on SW Pine St, and it is one of the 24 cities inside Metro's service boundary. For a tax return, that means Metro's regional income tax can apply here, while the Multnomah County tax paid by Portland residents who live in that county generally does not.

Many Sherwood returns start out simple: two W-2s, a mortgage, children and a retirement account or two. They get more involved when one spouse works in Portland, when someone starts a business from home, or when a household has its first year above a local tax threshold. Those are the moments when a CPA earns their place.

Sherwood's ZIP code, 97140, adds a wrinkle of its own. TriMet treats it as only partly inside its district, so two Sherwood businesses with the same ZIP code can have different payroll taxes.

Most of these questions have clear answers once the facts are on the table. The work is in gathering them: where each person in the house worked, which addresses fall inside which district, and which side income needs its own forms.

Metro SHS and wages earned in Multnomah County

The Metro Supportive Housing Services (SHS) personal income tax applies to Sherwood residents once taxable income passes the threshold. For tax year 2025, that threshold is $125,000 for single filers and $200,000 for joint filers, and the tax is 1% of income above it. For tax year 2026, it rises to $128,000 and $205,000. Full year residents file Form MET-40 with the City of Portland Revenue Division.

Preschool for All (PFA) is different. Sherwood residents are not Multnomah County residents, so they owe PFA only on income sourced in Multnomah County. A Sherwood couple who both work in Washington County will usually never file it.

Now picture a household where one spouse commutes to an office in Multnomah County. Part of that spouse's wages can count as county income, and on a joint return the household is measured against the $200,000 joint threshold for tax year 2025. Above it, a nonresident return on Form MC-40-NP may be due, with PFA figured on the household's Multnomah County taxable income above the threshold.

SHS returns follow the federal calendar and are typically due on 4/15. An extension gives more time to file but not more time to pay, so even a household that extends should estimate the SHS amount and pay it on time.

Home based businesses in Sherwood

Sherwood requires a city business license from any business or individual who advertises or otherwise presents themselves to the public as being in business, and from anyone located in the city. Home based businesses inside city limits need two things: a valid business license each year and a separate Home Occupation Permit, which goes to the Planning Department for review. Allow time for that review before you open, since the permit and license work together.

If your business has more than one location, Sherwood treats each branch as a separate establishment that needs its own license. Building and landscape contractors headquartered outside the city can use a Metro license, entering the Metro license number on the city form.

On the tax side, a home business brings its own questions: whether you qualify for a home office deduction, how to separate personal and business spending, and when to pay quarterly estimates. A CPA can set up simple bookkeeping from the start so the first Schedule C, the federal form for sole proprietor income, is not built from a shoebox of receipts.

Contractors based in Sherwood should look at both rules: the city license for being located in Sherwood, and Metro's regional contractor license for work across the region. Keeping both current, and recording their costs as business expenses, keeps the books clean.

Payroll and TriMet in 97140

TriMet lists Sherwood's ZIP code, 97140, as only partly inside its district. That means some Sherwood work addresses fall inside the TriMet district and some do not. An employer or self employed person here should check the exact address on TriMet's district map instead of relying on the ZIP code.

Inside the district, employers pay the TriMet transit payroll tax on wages for work done there, and self employed people pay it on net self employment earnings. TriMet lists the rate at 0.8237%. Separately, employers withhold the statewide transit tax of one tenth of 1% from employee wages, whether or not the address is inside TriMet.

Self employed people working from home should check their home address too. If it falls inside the TriMet district, net self employment earnings for work done there carry the transit tax, and that amount belongs in your quarterly estimates. Save a screenshot for your records.

If you are not sure which side of the line you are on, TriMet's interactive map gives the answer for a specific address, and it takes only a minute.

Planning ahead for a growing Sherwood household

Raises, a second job or a profitable side business can move a household across the SHS line without much warning. A review in the fall, before year end, shows whether withholding covers federal, Oregon and Metro tax together. It is far easier to adjust a paycheck in October than to find the money in April.

For tax year 2026, the Revenue Division raises its quarterly estimated payment threshold for local personal income taxes to $5,000. If your employer does not withhold SHS and you expect to owe more than that, quarterly payments may be expected. Sole proprietors also pay the SHS personal tax rather than the Metro business tax, so business profit flows straight into that calculation.

If the business keeps growing, a CPA can also help you decide whether an LLC or an S corp election makes sense, and what that would change on your returns.

Households that moved to Sherwood from Multnomah County during the year should also mention it. Part year residents can owe PFA on income earned while they lived in the county, plus county sourced income after the move.
