A catalog of tax-deduction patterns with available research references.
Browse the full catalog across 55 commonly-flagged deductions in ten categories — Business, Self-Employed, Home Office, Vehicle & Mileage, Real Estate, Energy Credits, Retirement, Education, Healthcare, R&D. Entries may include an IRC or secondary-source reference; verify the facts, current authority, and filing treatment before relying on a pattern.
- Entries show available IRC or secondary-source references for review
- Same shape your firm reviewer sees inside the scanner — redacted to illustrative patterns
- No signup required — browse the illustrative catalog on your own time
Browse the catalog
Pick a category, filter the cards.
Filtered URLs are shareable (the active category is reflected in the query string). Open any card to see the evidence the scanner looks for, the IRC citation that supports it, and the human-review caveat that decides whether it holds up.
For sales & client conversations
A citation chain that survives contact with an auditor.
Catalog entries include the available client profile, estimated range, evidence pattern, and failure-mode note. They are research aids; your firm's professional judgment is the next step, not the AI's.
Use the catalog as a sales asset (a single card goes into a client conversation), or pull a category into a partner meeting. Where an IRC reference is present, use it as a starting point for the next “where do these come from?” question.
