New look, same Cornerstone. Same team, same phone numbers, same service.

Contact us

Call and tell us what you need filed. A short conversation is usually enough for us to tell you what the work involves. We work with clients in all 50 states, so wherever you are is fine.

Reach us

Talk to a person

You do not need to come to us. Our office is in the Westmoor office park off West 104th Avenue, and visitors are welcome — but nearly all of our work is handled by phone, email, and mail. Most of our clients live nowhere near Colorado.

Before you call

Helpful, but not required

You do not need any of this to make the first call. It just makes the first conversation faster.

Which years

Roughly which tax years you need filed, and whether any have been filed already.

Your situation

Whether it is a personal return, a business, or both — and which state or states.

Any IRS letters

If you have received notices, having them nearby helps. Unopened is fine.

Get started

We are ready when you are.

Whether it is this year's return or a stack of years you would rather not think about, the call is the hard part.
