Tax Tip of the Week 4-28
Film Noir Mode: ON
“We must see your papers,” said the IRS agent from the shadows.
Claiming charitable donations?
Business mileage?
Home office?
Energy credits?
Tips or overtime deductions?
Documentation matters.
If you claim deductions without records, the IRS may deny the deduction and may assess accuracy-related penalties.
Just ask Thomas Langlois. In Langlois v. Commissioner, T.C. Memo. 2025-12, the Tax Court denied unreimbursed employee business expenses and partnership losses for lack of substantiation. He was also hit with accuracy-related penalties. Your Tax Pro may ask annoying questions like:
“Do you have a mileage log?”
“Was it written down at the time?”
“Who did you meet, where, when, and why?”
That is not because we are trying to ruin your day. It is because “trust me” is not a tax strategy.
Your documentation should be contemporaneous. If you drive to Gilford on May 6 to meet a client, record it that day: where you went, who you met, why you went, and how many miles.
Get in the habit of saving receipts and recording your actions.
Because in tax world, if it is not documented, it may not have happened.
We speak Tax, so you don’t have to.
