What happened

A long-haul owner-operator faced a review of meal and travel expenses claimed on the simplified per-diem method. We documented eligible travel days against logbooks and applied the correct long-haul meal deduction rate. The claims were substantially upheld, protecting a meaningful annual deduction.

Transportation files run on logbooks, per-diem meal claims and fuel tax reporting reconciled across every jurisdiction driven.

The rules this turned on

CRA audit and review

A review is won on documentation created at the time, not on explanations offered afterwards. The CRA asks for the source records behind a figure, and an unsupported claim is simply disallowed.

Why it bites: Most reassessments we reverse are not the result of a wrong position — they are the result of a correct position with no contemporaneous paper trail behind it.

Personal tax (T1)

T1 returns are due April 30, and June 15 for the self-employed — but any balance owing is due April 30 regardless, with interest compounding daily from that date.

Why it bites: The June deadline misleads a great many self-employed filers into paying two months late without realising it.

Expense claims

An expense is deductible where it was incurred to earn income and is reasonable in the circumstances. The business-use portion must be supported, which for vehicles means a logbook.

Why it bites: The CRA rarely argues that an expense category is wrong; it argues that the proportion claimed was never substantiated.

What this means for your business

Every engagement above was priced as a fixed fee agreed before the work started, and paid only once the client had reviewed the result. If any of this looks like your situation, the first step is a free 15-minute call — we will tell you plainly whether there is anything worth doing.
