An Oregon LLC is a federal pass-through by default: a single-member LLC is a disregarded entity and a multi-member LLC is a partnership, with profit flowing to the owners' personal returns. Oregon then taxes that income at a personal rate up to 9.9% and applies the Corporate Activity Tax on gross receipts above $1 million, but charges no state sales tax. An S-corporation election on Form 2553 can move part of the profit out of the 15.3% self-employment tax once net income passes $40,000-$60,000.
An Oregon LLC is a federal pass-through by default, so it pays no entity-level federal tax. A single-member LLC is a disregarded entity taxed on Schedule C of the owner's Form 1040; a multi-member LLC is a partnership that files Form 1065 and issues K-1s to members. Profit flows to the owners' personal returns in both cases. The LLC can override the default by electing S-corporation or C-corporation treatment when that lowers total tax. The federal default is the starting point for every Oregon LLC before any state tax or election is considered. The LLC itself is a state-law entity, not a federal tax classification, so the same Oregon LLC can be taxed four different ways: disregarded, partnership, S-corp, or C-corp. Choosing among them is a tax decision made after formation, and it can change from year to year as profit grows.
Yes. Oregon taxes pass-through LLC profit at a personal income tax rate up to 9.9%, applied on the owner's Oregon return. Oregon also applies the Corporate Activity Tax on commercial activity above $1 million in gross receipts. The Corporate Activity Tax is a gross-receipts tax separate from income tax, so it applies to revenue rather than net profit once the $1 million threshold is crossed. Oregon charges no state sales tax, which lowers the compliance burden for retail and ecommerce sellers. A Wyoming or New Mexico LLC carries no state income tax at all. An owner who lives outside Oregon and runs the business from another state weighs whether Oregon-source income creates an Oregon filing obligation at all. A founder whose priority is a light tax profile with owner privacy forms in Wyoming or New Mexico and foreign-qualifies into Oregon only when local operations require it.
No. Oregon charges no state sales tax, one of a handful of US states with none, so an Oregon LLC collects no state sales tax on in-state sales. This benefits retail, restaurant, and ecommerce sellers who avoid sales-tax collection and remittance at home. The personal income tax up to 9.9% and the Corporate Activity Tax on gross receipts above $1 million offset the benefit for higher earners. Sales shipped into other states can still create sales-tax nexus under each destination state's own economic-nexus rules. The absence of a sales tax also means no state resale certificate or sales-tax registration to maintain in Oregon, which removes a recurring compliance task that sellers in most other states carry. Income tax and the Corporate Activity Tax remain the state charges to plan for as revenue scales.
An S-corp election becomes worthwhile once net business income passes $40,000-$60,000 per year. Below that, the payroll-compliance cost outweighs the self-employment tax saved. An LLC elects S-corporation treatment by filing IRS Form 2553. The election keeps pass-through treatment but splits income into a reasonable salary subject to payroll tax and distributions that avoid the 15.3% self-employment tax on the non-salary portion. The election adds payroll filings and a reasonable-salary requirement, so it fits an owner with steady profit above the threshold. The reasonable salary must reflect what the work is worth, because the IRS challenges a salary set artificially low to shift profit into distributions. The saving comes from the distribution portion, which escapes the 15.3% self-employment tax while the salary portion still carries payroll tax.
Default LLC owners pay 15.3% self-employment tax on net business income: 12.4% Social Security up to the annual wage base of $168,600 plus 2.9% Medicare with no cap. This is on top of federal and Oregon income tax. An S-corp election moves the non-salary portion of profit out of self-employment tax, which is the main reason owners elect it above $40,000-$60,000 in net income. The election adds payroll compliance and a reasonable-salary requirement. Self-employment tax is a federal charge and applies regardless of the state where the LLC is formed.
It depends on Effectively Connected Income. A non-resident-owned Oregon LLC with no US-source effectively connected income files Form 5472 with a pro-forma Form 1120 each year but owes no US income tax. With US ECI, the profit is subject to US income tax. A foreign-owned single-member LLC files Form 5472 annually; a multi-member LLC files Form 1065 with K-1s. An ITIN at $299 is available where personal US tax filing requires one. Anonymousllc.co partners with US tax preparers familiar with non-resident filings. Many non-resident service businesses that never set foot in the US have no effectively connected income, so their US federal income tax is zero and the annual obligation is the information return alone. Oregon-level tax follows only if the LLC has Oregon-source income, which a fully remote foreign owner may not generate.
Form 5472 is an IRS information return required for any US disregarded entity with 25% or more foreign ownership. A non-resident-owned single-member Oregon LLC files it annually alongside a pro-forma Form 1120. The form reports transactions between the LLC and its foreign owner, and the penalty for not filing starts at $25,000. It is an information return, not an income tax return, so filing it does not by itself create a tax bill. Anonymousllc.co connects non-resident owners with preparers who handle the 5472 and pro-forma 1120 each year.
Under the March 21, 2025 FinCEN interim final rule, domestic reporting companies are exempt from BOI reporting, so a US-formed Oregon LLC is currently exempt. The exemption covers entities created in the United States. Foreign reporting companies formed outside the US remain obligated to file BOI reports at $150 per report. The rule status can change, so Anonymousllc.co tracks FinCEN updates through the BOI status tracker and files on request if the requirement returns for domestic entities. Most Oregon LLCs are domestic and file nothing right now. BOI reporting is a federal ownership disclosure to FinCEN, separate from income tax and from Oregon's public member listing. It does not affect how the LLC is taxed; it is an anti-money-laundering filing, and its current exemption for domestic entities is the reason a US-formed Oregon LLC has no BOI step at present.
An Oregon LLC is $397 all-in through Anonymousllc.co: a $297 service fee plus the $100 state fee, covering state filing, registered agent year one, operating agreement, EIN, and four to five US bank applications. A Wyoming anonymous LLC is also $397 all-in and carries no state income tax, which suits an owner who wants privacy and a lighter tax profile and foreign-qualifies into Oregon. New Mexico is $347, Delaware $407, and Nevada $722. Formation completes in 5-10 business days regardless of the state chosen. The tax treatment of the LLC does not change the formation price: the $397 covers the entity, and the S-corp election, the 5472 filing, or an ITIN are handled separately as the owner's tax situation requires. Anonymousllc.co sets up the entity and connects the owner with preparers for the annual filings.
