Annual Reports
Filed on time, in every state where you operate.
Mainstay handles the filings, registered‑agent service, and annual compliance that keep your business standing — so the legal scaffolding is never the thing in your way.
We started Mainstay because the people forming companies deserve a filer who treats the work like a craft — accurate the first time, returned on a calendar you can plan around, and answered by a person who knows your file.
From a desk in Sioux Falls, our team prepares and files entity documents in all 50 states. We act as registered agent for thousands of LLCs and corporations, forward service of process the day it arrives, and keep our clients on the right side of every annual deadline.
No upsells. No drip campaigns. Just the paperwork, done the way you'd do it if it were yours.
Each filing is reviewed by a human formations specialist before it leaves the office. State rejections are an internal failure, not a billable revision.
Established 2014. Our oldest registered‑agent clients have been with us since the year we opened. Continuity is the product.
