When Poor Records Destroy Legitimate Deductions —
Lessons from Sami v. Commissioner (T.C. Memo 2026‑69)
The Tax Court’s decision in Suleiman Sami v. Commissioner (T.C. Memo 2026‑69) is a powerful reminder for business owners, gig‑workers, influencers, and anyone filing a Schedule C: if you don’t keep proper records, the IRS will treat even legitimate business expenses as personal — and disallow them.
Mr. Sami ran a transportation service, ticket‑resale business, and social‑media influencer operation. He incurred real business expenses: vehicle mileage, tolls, celebrity‑related marketing events, credit‑card processing fees, and more. But his recordkeeping was inconsistent, incomplete, and often reconstructed after the fact.
The Court emphasized:
“Mr. Sami did not keep books and records for his business.”
“A taxpayer must maintain records sufficient to enable the Commissioner to determine the correct tax liability.”
And even where expenses were clearly business‑related, the Court repeatedly noted: “The exact amounts of the expenses, however, are murky.”
As a result:
❌ Cost of goods sold disallowed
He couldn’t prove certain ticket purchases were actually resold.
❌ Contract labor disallowed
He paid relatives to drive — but had no documentation.
❌ Many marketing and event expenses disallowed He attended Grammys, Emmys, celebrity meet‑and‑greets — but lacked business‑purpose substantiation.
✔ Some vehicle expenses allowed — but reduced by 20% The Court applied the Cohan rule and cut his deduction because his mileage estimates were incomplete.
✔ Credit‑card processing fees allowed
These were well‑documented.
Key Lesson for Business Owners & Influencers The IRS does not care how legitimate your business is — only how well you document it.
Even when the Court believed Mr. Sami did incur business expenses, it still disallowed them because he failed to maintain:
- mileage logs
- receipts
- proof of business purpose
- records of payments to helpers
- proper separation of personal vs. business charges This case is a textbook example of how poor recordkeeping converts real business expenses into nondeductible personal expenses.
Practical Takeaway for CPAs & Clients
If you operate a Schedule C business — transportation, consulting, gig work, influencer marketing, ticket resale, or anything similar — you must:
- Keep contemporaneous mileage logs
- Maintain receipts and proof of business purpose
- Separate personal and business bank/credit card activity
- Document payments to helpers or contractors
- Use accounting software or a simple ledger Otherwise, the IRS will reconstruct your income, deny your deductions, and impose penalties — just as it did here.
