Real People, Real Relief
I owed the IRS $71,000 and was terrified. Sentinel negotiated an Offer in Compromise and I settled for $8,400. They gave me my life back. I can't recommend them enough.
The IRS had levied my bank account. Sentinel got the levy released in days and set up a payment plan I could actually afford. Calm, professional, and they handled everything.
Six years of unfiled returns kept me up at night. They filed all of them, cut the penalties way down, and I'm finally caught up and sleeping again. Worth every dollar.
They defended me through a full IRS audit and I ended up owing almost nothing. Having real Enrolled Agents in the room changed everything. I never spoke to the IRS once.

Frequently Asked Questions
Can you really settle my tax debt for less than I owe?
Often, yes — through an Offer in Compromise, many clients settle for a fraction of what they owe. It depends on your income, assets, and expenses. We'll tell you honestly on your free call whether you're likely to qualify and what a realistic outcome looks like.
The IRS levied my bank account / garnished my wages. Can you stop it?
Yes, and fast. Once we file a power of attorney we contact the IRS immediately to request a release and halt further collection while we work out a resolution. Time matters here, so reach out as soon as you can.
I have years of unfiled returns. Am I in trouble?
You're not alone, and it's fixable. We prepare and file your back returns, work to reduce penalties, and get you back into compliance — which is almost always the first step to any settlement.
Will I have to talk to the IRS myself?
No. As licensed Enrolled Agents and CPAs, we're authorized to represent you before the IRS at every level. Once you hire us, we handle all communication — you don't have to speak to them at all.
How long does resolution take?
It varies with your situation — a levy release can happen in days, while an Offer in Compromise may take several months. We'll give you a realistic timeline up front and keep you updated at every step.
How much does it cost, and is my consultation private?
Your initial consultation is free and completely confidential. If we take your case, we quote a flat fee up front based on the work involved — no hourly surprises. For most clients the savings far outweigh the fee.
