We built the tool
we wished existed
REPSShield started from a real problem: a real estate investor with a strong REP status claim lost a significant deduction in an IRS examination — not because they lacked the hours, but because they could not prove them in the format the IRS requires. A spreadsheet summary was not enough. A reconstructed calendar was not enough. A CPA letter was not enough.
We built REPSShield so that documentation problem never has to happen again.
Help real estate professionals track REP status with confidence and stay IRS-compliant
Qualifying as a Real Estate Professional under IRS Section 469 is one of the most powerful tax strategies available to active real estate investors. It can unlock the ability to deduct rental losses against W-2 income, convert passive losses into active deductions, and dramatically reduce tax liability.
But the IRS places the burden of proof entirely on the taxpayer. You must demonstrate that you spent more than 750 hours in qualifying real property activities, and more time in real estate than in any other occupation — with contemporaneous documentation for each hour.
REPSShield exists to carry that burden automatically, so real estate professionals can focus on their properties instead of their paperwork.

Why spreadsheets and manual logs are not enough
Most real estate professionals underestimate how high the IRS's documentation bar actually is. Here is what that means in practice.
The IRS expects contemporaneous logs
Tax court rulings consistently show that reconstructed logs — pieced together weeks or months later — carry little weight. REPSShield creates timestamped, contemporaneous documentation at the moment activities occur, the same standard the IRS applies.
Spreadsheets fail at scale
Tracking hours across 5, 10, or 20 properties in a spreadsheet means re-categorizing every entry by hand against IRS rules you have to memorize yourself. One missed category or uncounted hour can invalidate a year of losses. REPSShield enforces the IRS framework automatically.
The 750-hour test is only half the equation
Most investors focus on the 750-hour threshold and overlook the equally important more-than-half-time test. They also miss that REP status and material participation are two separate determinations — and you can fail material participation on individual properties even after qualifying as a REP. REPSShield tracks all of these simultaneously.
CPAs need IRS-formatted evidence, not summaries
Your CPA cannot protect you in an audit with a summary you hand them in April. They need the underlying contemporaneous log showing each activity, each property, each date, and the IRS category it belongs to. REPSShield generates this automatically in a format your CPA can attach directly to your return.
Our Story
Built by an engineer who lived the problem
REPSShield was founded in 2023 by Edgar Estrada, a software engineer with over 10 years of experience in real estate data compliance. After watching investors lose legitimate REP deductions — not because they lacked the hours, but because they could not prove them in the format the IRS requires — Edgar set out to build the tool that should have existed all along.
Edgar started by talking to CPAs who specialize in real estate taxation. The same story came up in every conversation: clients arrive in March or April with a spreadsheet they filled in from memory, or a calendar export with no activity categorization. CPAs were spending hours manually auditing these logs before they could even begin preparing the return. And when the IRS pushed back, neither the investor nor the CPA had the evidence to defend the deduction.
He built the first version of REPSShield for a small group of CPAs and their clients. The feedback was clear: the IRS documentation format matters as much as the hours themselves. An audit-ready log needs timestamped entries, IRS-category labels, property attribution, and a Form 8582-compatible summary. REPSShield generates all of that automatically.
Today REPSShield syncs with Google Calendar, Outlook, and Apple Calendar to capture qualifying activities as they happen. Its AI engine categorizes entries against the 14 IRS-recognized activity types and flags anything that may not qualify. At tax time, investors export a PDF report that their CPA can attach directly to the return — one that is formatted to withstand IRS scrutiny.
Edgar continues to build REPSShield in public, shipping features based on direct feedback from real estate investors and CPAs.
The IRS does not care how hard you worked to qualify. They care whether you can prove it, in their format, with documentation you created at the time. That is the only standard that matters in an audit.
— Edgar Estrada, after reviewing 40+ REP audit case files
