IRS audit data tells a consistent story: self-employed income is the least-verified category in the U.S. tax system — and inadequate recordkeeping is the primary driver of the gap.
The IRS projects a $696 billion gross tax gap for tax year 2022. Underreporting on timely filed returns accounts for $539 billion of that — more than three-quarters — with business income as the primary source.

For W-2 wage earners, the IRS estimates roughly 1% noncompliance. For Schedule C proprietorship income — with no employer withholding and no third-party reporting — that figure reaches 55%.

About half of the individual income tax gap accrues to proprietorships, partnerships, and S-corps — income sources where there is little or no third-party data for the IRS to verify what was filed.

That gap is a recordkeeping problem before it is anything else — and recordkeeping is exactly what DeductSam does for you.

I'm a firefighter who picked up side income to support my family — a small business and a rental on top of the day job. I never had time for the tax side, so each spring I'd dump a year's paperwork on my CPA, hope for a good return, and move on — with no real understanding, and plenty of missed opportunities.
So I started using AI tools to actually learn the system, built myself an assistant that tracked my expenses and taught me as it went. When friends saw it, they all asked the same thing: could they use it too?
