Fixed fee · Audit defense in writing · Built to the IRS's own guide
We turn a property and a few tax facts into an audit-defensible study. You speed up your deductions, often $50,000 to $500,000 in year one. Every study is backed by The Audit Defense Pledge, in writing: lose ground on our study at audit and we refund part or all of your fee. Fixed fee starting at $497, no contingency, ready in 45 days.
The estimate is the pitch. It is instant, free, and nobody calls you unless you ask us to.
Is this you?
What it is
A cost segregation study breaks your building into its parts. Some parts wear out faster than the shell. The IRS lets you depreciate those parts over 5, 7, or 15 years instead of 27.5 or 39. That moves big deductions into your early years, when they help the most.
It works best when your building basis is over $200,000, you are in a high tax bracket, and you can use the losses now, as a real estate pro or a short-term rental host. Our study tells you the exact number before you commit.
The first two rows can move to year one. That is the$78,866 shift in this study.
The law just changed
The One Big Beautiful Bill Act made 100% bonus depreciation permanent. It applies to property acquired and placed in service after January 19, 2025. That means the short-life parts a study finds can often be deducted in full, in year one.
Bought in early 2025? Transitional rules can apply, and some dates fall under a 40% rate instead. We check your dates as part of the study.

How it works
Share the address, a few tax facts, and some photos. It takes about 15 minutes. Extra details make the study stronger.
Your photos, plans, and records become a date-stamped evidence log. We measure site work from satellite imagery too.
We sort building parts into 5, 7, and 15-year groups. We price each part and back it up with court cases.
On the Expert Reviewed tier, an accountant on our team reviews and signs the study before it is released.
A robust, comprehensive PDF with 42 itemized parts, photos, our published library of court and IRS authorities, and a state conformity chart. We leave no stone unturned.
