The research a small firm cannot run on its own

Signal is a public-facing tax-research desk for CPAs and small-business owners. Each benchmark below compiles the kind of memo a big-firm partner gets from an internal research department on day one of busy season. Statute, eligibility, typical recovery range, common substantiation miss, IRS source link, all on one page.

This is research, not professional advice. Use it with your CPA, or ask us to run a custom benchmark for your firm at no cost.
