How do I file sales tax in Oregon?

You don't. Oregon imposes no general sales tax in 2026, so there is no Oregon sales tax permit to hold and no Oregon sales tax return to file — not even a zero return. You still owe sales tax in states that do impose one, so test each destination state against its own threshold rather than against Oregon's.

How often do I file sales tax returns in Oregon?

Never, because Oregon levies no general sales tax and therefore assigns no filing frequency. Filing cadences (monthly, quarterly, annual) are assigned at registration by the states that do impose a sales tax, based on your expected liability there.

When are Oregon sales tax returns due?

There are no Oregon sales tax returns and so no due dates. Your deadlines live in the states where you actually hold a permit — check each of those revenue agencies' filing calendars rather than a generic rule.

Do I need a Oregon sales tax permit at all?

Not for sales tax. Oregon issues no general sales tax permit because it imposes no such tax. Other business-level taxes and licenses can still apply to in-state activity, so confirm your obligations with the Oregon revenue agency if you have people, an office, or inventory there.

Oregon has no general sales tax

Oregon does not levy a general state or local sales tax, so sales delivered into Oregon carries no sales-tax registration, collection, or filing obligation — there is no economic nexus threshold to cross and no rate to charge.

Oregon has no state or local general sales tax. Sellers do not need to register or collect sales tax on transactions shipped to Oregon customers. Oregon does impose a Corporate Activity Tax (CAT) on certain businesses with Oregon-source revenue over $1M, but this is not a sales tax.

What still deserves a look in Oregon

Sales-tax-free does not mean tax-free. Several no-sales-tax states impose other business-level taxes on in-state activity — confirm what applies to you with the Oregon revenue agency.
Shipping from Oregon changes nothing about your duties elsewhere. Sales delivered into other states are tested against those states’ thresholds, not Oregon’s absence of one — start with the nexus calculator to see where you owe.
Storing inventory in Oregon (a 3PL, an FBA centre, your own warehouse) creates no OR sales-tax duty, because there is no OR sales tax to collect.
