"We are so fortunate to have A1 do our taxes. Honorable, integrity, very personal..."
Founded in 1987 on Oklahoma City's east side, A-1 Accounting & Tax has spent nearly four decades quietly building one of the most loyal client books in the metro. We serve individuals, families, retirees, small businesses, and self-employed professionals — many of whom we've worked with for twenty years or more.
Karen, Michael, and the rest of our team approach every return the same way: carefully, personally, and with a real interest in the people sitting across the desk. We're not a chain — we're the firm you call when you actually want someone to answer the phone.
From a simple W-2 return to multi-year IRS resolution and ongoing bookkeeping for your small business — we handle the entire range, in-house, with people you'll see year after year.

Get help todayDon't wait for April. Year-round strategy sessions to minimize liability, optimize retirement contributions, structure new ventures, and prepare for life events that move the needle.
Plan aheadA-1 isn't built for volume — it's built for relationships. Most of our clients started years ago, came back the next April, and never left. Their kids are clients now. Some of their grandkids, too.
Honor. Integrity. The kind of personal attention you only get from a firm that's truly local — and truly invested in the community it serves.
We sit on the east side of Oklahoma City off Douglas Boulevard. Drop in, sit down, and let's talk through whatever you've got — a return, a letter from the IRS, a new LLC, a curiosity about whether you're missing deductions. There's no charge for the first conversation.
We genuinely like meeting your family. The lobby is kid-friendly with toys, magazines, and a quiet corner for the grandparents. Most of our clients bring everyone in — that's by design, not by accident.
Karen and the team take continuing education seriously. Tax law changes constantly — and we keep current so you don't have to. When something new shifts your situation, we'll be the ones who notice first.
Many of our clients have been with us for 15, 20, even 30+ years. We learn your story, your business, your goals — and that depth of context shows up in every return we file and every recommendation we make.
Taxes can feel intimidating. Our clients consistently describe us as patient, calm, and easy to understand. There are no dumb questions in our office — only ones we haven't gotten to yet.
A small, deeply experienced team you'll actually get to know — not a rotating cast of seasonal preparers.
Principal · Tax & Advisory
Karen has been preparing taxes on the east side of OKC since 1987. Clients describe her as sweet, patient, and constantly up-to-date on the latest tax law. She's the heart of the practice.
Senior Tax Preparer
Knowledgeable, calm, and easy to work with — Michael is the steady hand many of our newer clients meet first. He specializes in individual returns and small business consulting.
Bookkeeping & Payroll Lead
Sarah runs the monthly close for our small-business clients. QuickBooks-certified, deeply organized, and the person who makes sure your books are always audit-ready.
Enrolled Agent · IRS Resolution
David handles audits, letters, back taxes, and the trickier IRS conversations. Twenty years representing taxpayers before federal and state revenue agencies.
Office Manager · Client Services
Linda is the friendly voice on the phone and the person who keeps the office running. Scheduling, intake, and the warm welcome you get the moment you walk through the door.
Tax Associate
Jason joined us after completing his accounting degree at OU. He works alongside Karen on individual returns and brings strong skills with newer cloud accounting tools to the firm.
We invest in memberships, certifications, and partnerships that make us better — and that means better outcomes for the people we serve.

Michael was very easy to work with and very knowledgeable.
We are so fortunate that my husband and I have A1 to do our taxes. They are honorable, have integrity and very personal in their interaction with us. They do an excellent job. We have never had any trouble with our taxes and tax returns. Thank you A1!
I've been coming to Karen since 2008 and she is super nice. The whole entire staff is very family-oriented and super nice. I do not want anyone preparing my income tax, but A-1 Accounting & Tax Services!
Karen is constantly keeping up to date with the changes in tax law. She is very helpful to explain any questions you have and is just a sweet lady. They have a kid friendly lobby and plenty of magazines to choose from. My family and I will never go anywhere else.
It was great.. wonderful.. I liked Michael who did taxes.. he was patient.. calm and understanding.. the best place ever I will be doing taxes. Thank you for all you did.
I love this place. They are always so nice and friendly. I also love that it's a kid friendly environment.
Great service. I've been going here 12 years — they are the best!
Top notch service. Michael Johnson is incredibly helpful and does a good job.
The Johnsons are such a blessing! Professional throughout!
A small, steady firm where careers are built — not burned out.
We hire slowly and keep our people for years. If you're looking for a desk where you can do good work, learn from experienced colleagues, and actually go home at a reasonable hour during the off-season — let's talk.
We're a few minutes east of downtown Oklahoma City, just off N Douglas Boulevard. Easy parking, kid-friendly lobby, and a fresh pot of coffee on most mornings.
Whether you're filing for the first time, switching from another preparer, or sitting on an IRS letter you don't know what to do with — send a note. We answer every message ourselves.
Call us, walk in, or send a message — we'll handle the rest.
