Federal tax treatment
By default, a single-member LLC is often disregarded for federal income tax purposes and a multi-member LLC is often taxed as a partnership. An eligible LLC can elect corporate tax treatment. The choice affects federal returns, owner reporting, payroll, and estimated tax planning.
Oregon Corporate Activity Tax
Oregon CAT is measured on Oregon commercial activity, not simply profit. Businesses with Oregon commercial activity of $750,000 or more may need to register. A return and payment obligation generally use the higher more than $1 million thresholds described by the Oregon Department of Revenue, with deductions and exclusions that can affect the calculation.
CAT is not the same as a retail sales tax, income tax, EIN, or annual LLC renewal.
No general state sales tax
Oregon does not have a general state sales tax. A business can still have other tax obligations, including CAT, employer withholding, local taxes, industry taxes, or tax obligations in another state where it sells or operates.
Employer obligations
When hiring, review Oregon withholding, unemployment insurance, new-hire reporting, wage reporting, and workers’ compensation requirements. The EIN is only the federal identifier; it does not finish Oregon employer registration.
Keep the filings separate
- LLC formation: creates the Oregon LLC
- Annual renewal: $100 to maintain the state entity record
- EIN: federal IRS identifier
- CAT registration and returns: based on Oregon commercial activity
- Employer accounts: withholding, unemployment, and related obligations
- Licenses and permits: local, professional, and industry rules
Tax FAQ
Does every Oregon LLC pay CAT?
No. CAT obligations depend on Oregon commercial activity and the applicable thresholds, exclusions, and filing rules.
Does Oregon’s lack of sales tax mean no tax registration?
No. CAT, payroll, local, industry, and other state obligations can still apply.
Does the $100 annual renewal pay Oregon taxes?
No. It is a Secretary of State entity renewal fee, not a tax return or tax payment.
Is an EIN free?
Yes. EINs are free when requested directly from the IRS.
