Purnell Tax Solutions — Registered Tax Preparer · CTEC · ERO · 25+ Years Experience

Bank-evidenced pre-fills (gold BANK tag): storage, tolls, insurance, and internet amounts load automatically per year from the completed USC Credit Union statement analysis. Verify business purpose/percentage before they go on the 1040-X — evidenced is not the same as deductible.

Cash = highest audit risk. Every cash payment needs: amount, date, recipient name, business purpose, matching bank withdrawal. Signed acknowledgments from recipients are ideal documentation.

TY2021 assessment caution: tax assessed ($45,023) far exceeds what the filed net profit ($10,117) would generate — a later IRS assessment is on the account. Assessment history is being reconciled; do not anchor savings expectations to original-return figures until that review completes.

TY2020: filed return not yet obtained — baseline TBD. Amounts entered under TY2020 are preserved when you toggle years.

Meals are 50% deductible. Enter full receipt amount — the 50% limitation is applied on the 1040-X, not here.

Vehicle method consistency: standard mileage and actual expenses cannot be combined for the same vehicle in the same year. Vehicle identity (BMW per bank feed vs F-150 per interview) and the method behind the filed $1,173 must both be confirmed first.
