Frequently asked

Washington Articles of Amendment questions.

What are Articles of Amendment at the Washington Secretary of State?

They are the filing you submit to the Washington SOS to officially change something in your original formation document, the entity name, address, business purpose, share structure, or management. The change is not legal until Washington accepts the amendment. We prepare and file the correct Washington amendment for whatever you are changing on the record.

When do I need to file an amendment in Washington?

When you change information that appears on your public Washington record: a new company name, a change in authorized shares, a shift in management structure, or an updated business purpose. Internal changes usually go in the Operating Agreement instead. We determine whether your change actually requires a Washington amendment.

How do I change my company name with Washington?

You file Articles of Amendment with the Washington Secretary of State stating the new name, which must be available and meet Washington naming rules, and the change takes effect when accepted, after which you update the IRS, banks, and licenses. We check name availability and file the Washington amendment so the change goes through cleanly.

Is an amendment the same as an annual report?

No: an annual report is a routine periodic filing to keep information current; an amendment is a one-time change to your formation document. Filing the wrong one delays your change. We file the correct Washington document so your update actually takes effect rather than bouncing back.

What can I not change with an amendment?

Some changes need a different filing: converting entity type uses a conversion or merger, dissolving uses a dissolution, and internal-only terms go in the Operating Agreement, not a Washington amendment. We map your specific change to the right Washington filing so it is not rejected as the wrong document.

How much does a Washington amendment cost?

Washington sets an amendment filing fee that varies by state and entity, with expedited options costing more. Because it changes, we show the current Washington figure and pass it through at cost. Our service pricing is on the pricing page rather than quoted where a number could go stale.

Do I need to update other agencies after a Washington amendment?

Yes: after Washington accepts a name or structure change, you generally update the IRS, your bank, licenses, and any states where you are foreign-qualified, or records fall out of sync. We flag the downstream Washington and federal updates so the change is reflected everywhere, not just at the SOS.
