Portland, OR Bookkeeping Services — No Sales Tax, Four Other Filings
Last Updated: October 6, 2026Portland has no sales tax and one of the most layered local tax stacks in the country. The city charges a Business License Tax at 2.6% of net income, with businesses under $75,000 in gross receipts exempt for tax years beginning in 2026, rising to $100,000 from 2027. Multnomah County adds its Business Income Tax at 2% of net income, exempt under $100,000 of gross receipts. Above those sits Oregon’s Corporate Activity Tax at $250 plus 0.57% of commercial activity over $1 million, plus state income tax. Four separate measures of the same business, each with its own threshold — and every one of them derived from the books.

Running the Numbers in Portland
Portland’s business base is dense with exactly the kind of company these taxes bite: independent agencies and consultancies, athletic and outdoor brands, breweries and food producers, software firms, and a very large population of sole proprietors and single-member LLCs working as contractors.
The pattern we see repeatedly is a business comfortably under one threshold and over another — exempt from the county tax but not the city, or under the CAT threshold on Oregon-sourced activity while booking considerably more in total. The thresholds are measured differently, so you cannot reason from one to the others. You have to be able to produce each number.
Portland Tax Cheat Sheet
| Item | Rate / Fee | Deadline |
|---|---|---|
| Portland Business License Tax | 2.6% of net income. Exempt if gross receipts from all business activity are under $75,000 for tax years beginning in 2026, and under $100,000 from 2027 | Annually, with the city return |
| Multnomah County Business Income Tax | 2% of net income. Exempt if gross receipts, in and outside the county, are under $100,000 | Annually, on the combined return |
| Oregon Corporate Activity Tax | $250 plus 0.57% of taxable Oregon commercial activity above $1 million — measured on receipts, not profit | Annually, with estimates for larger taxpayers |
| Oregon income / excise tax | On Oregon taxable income, separately from the CAT | Annually, with estimated payments |
| Sales tax | None in Oregon | — |
City of Portland Revenue Division, Multnomah County and Oregon Department of Revenue, checked 3 October 2026. The Portland Business License Tax gross-receipts exemption is $75,000 for tax years beginning on or after 1 January 2026 and $100,000 from 1 January 2027. Rates and thresholds change — confirm with each authority or your CPA.
Four Filings, Four Different Thresholds
The Portland stack is unusual because the taxes do not measure the same thing. The city and county taxes are charged on net income but their exemptions are tested on gross receipts. The state CAT is charged on Oregon commercial activity — receipts, not income. State income tax is on taxable income.
So a consultancy with $120,000 of gross receipts and $60,000 of net income is above the county exemption and above the city exemption, pays both on net income, and is nowhere near the CAT threshold. A distributor with $1.2 million of receipts and $30,000 of net income pays very little city and county tax but is in CAT territory.
You cannot shortcut from one answer to another, and estimating any of them from a bank balance does not work. The only efficient approach is a properly reconciled set of books that produces gross receipts and net income on demand.
The Exemption Thresholds Move — and They Are Tested on Gross
Portland raised its Business License Tax gross-receipts exemption to $75,000 for tax years beginning on or after 1 January 2026, rising to $100,000 from 2027. That is genuinely helpful for the smallest businesses, and it is also a moving target that an owner is unlikely to track.
The trap is that the exemption is tested on gross receipts from all business activity, not Portland activity and not profit. A sole proprietor doing $90,000 of work, most of it for clients outside the city, is tested on the full $90,000. Someone who assumes the test follows their taxable income, or their Portland-only revenue, will get it wrong in both directions.
We keep gross receipts recorded cleanly and separately from net income precisely so this test can be applied correctly — and we flag it when a client approaches a threshold rather than after they have crossed it.
Sole Proprietors and Contractors Are in Scope Too
A point that surprises people: these are business taxes, not corporate taxes. A sole proprietor or single-member LLC operating in Portland can owe the city Business License Tax and the Multnomah County Business Income Tax on the same income reported on their personal return, once they are over the gross-receipts exemptions.
For the large number of Portland freelancers, consultants and creative contractors operating without an entity, that means business bookkeeping matters even though there is no company. Business income and expenses have to be separated from personal spending cleanly enough to produce a defensible net income figure for two local returns.
Our Standard plan at $75/month covers exactly this: five hours, monthly reconciliation, and a profit and loss that stands up.

Portland Bookkeeping FAQs
What is the Portland Business License Tax?
A city tax of 2.6% on net income from business activity in Portland. Businesses are exempt if gross receipts from all business activity are under $75,000 for tax years beginning on or after 1 January 2026, rising to $100,000 from 1 January 2027. Note that the exemption is tested on gross receipts while the tax is charged on net income — two different figures.
What is the Multnomah County Business Income Tax?
A county tax of 2% of net income, with an exemption where gross receipts from all business activity inside and outside the county are under $100,000. It is filed alongside the Portland city return, and like the city tax it applies to sole proprietors and single-member LLCs as well as companies.
Do Portland freelancers really owe city and county business tax?
Once over the gross-receipts exemptions, yes — these are taxes on business activity rather than on corporate entities, so an unincorporated consultant or contractor can owe both. That is why separating business from personal spending matters even without a company: both returns need a defensible net income figure.
Oregon has no sales tax, so is bookkeeping simpler here?
In one way, genuinely yes — no sales-tax collection, remittance or reconciliation. In another, no: Portland businesses face a city tax, a county tax, the state CAT and state income tax, each measured differently, and selling outside Oregon can create sales-tax obligations in other states. The compliance load moved rather than disappeared.
Do you have a Portland office?
No. We are a fully virtual bookkeeping company — founded in Vienna, Virginia on May 25, 2005 and headquartered in San Juan, Puerto Rico today, US-registered with delivery centers in India, which we disclose on our About page. We are not going to imply a Portland storefront we do not have. What we do have is Portland clients served remotely since 2005, a dedicated bookkeeper on plans from $75/month, and a 100% money-back guarantee on your 1st retainer, refundable on the unused balance.
