Documenting Auto Expenses

In September, the Tax Court in a summary decision upheld the Service’s disallowance of an auto expense deduction of a traveling salesperson due to lack of substantiation (Niyitegyeka, T.C. Summ. 2008-129). It was obvious that the taxpayer traveled for business and would ordinarily be entitled to a deduction, but the submitted evidence was too weak to allow it.

BACKGROUND

Section 6001 requires taxpayers to keep records to substantiate their tax liability. In the absence of such evidence, expenses can be estimated using circumstantial evidence per Cohan, 39 F.2d 540 (2d Cir. 1930). However, section 274(d) overrides the Cohan rule and requires a taxpayer to substantiate auto expenses (along with a few others).

Temp. Treas. Reg. § 1.274-5T(c)(2) expands upon the substantiation rule. The regulation states, “An account book, diary, log, statement of expense, trip sheet, or similar record must be prepared or maintained in such manner that each recording of an element of an expenditure or use is made at or near the time of the expenditure or use.” This means the record does not have to be documented at the exact same time as the expense, but it must be done within a reasonable time so that the time, place, amount, and business purpose can be recorded. The regulation gives the example that maintaining a log on a weekly basis is near enough to the expenditure to count as proper substantiation. The evidence may be written or recorded on an accessible computer memory device. The taxpayer may omit certain confidential information from the records as long as the information is available upon request.

NIYITEGYEKA

In Niyitegyeka, the taxpayer was a traveling salesperson in training. He would go to his employer’s office in Manhattan and then drive to his customers’ locations. The employer’s policy was to not reimburse trainees for expenses related to this type of travel, including hotels, meals, and mileage. The taxpayer traveled often and went as far as Queens, New Jersey, and Connecticut. These facts were not in dispute.

Because the travel was definitely for business and the expenses were not reimbursable, a deduction for business mileage was proper. However, upon examination, the taxpayer did not present any evidence to substantiate the mileage. Thus, the Service disallowed the deduction. The taxpayer claimed that he kept his records in his car, which had been stolen. The taxpayer filed a police report and the car was later recovered, but the business records were gone.

The Tax Court gave the taxpayer the opportunity to present other evidence besides a contemporaneous log or receipts. Accordingly, the taxpayer presented a computer listing, purportedly from the employer, that detailed the dates, names, and amounts of his draw and commission activities.

According to the Tax Court judge who heard the case, this evidence was insufficient to justify granting the deduction, and the IRS’s decision to deny the deduction was upheld. Specifically, the judge took issue with the following:

Accordingly, the court found that the listing was not sufficient evidence to support the deduction that the taxpayer sought. The judge noted that no evidence presented in this case provided “a rational basis on which we may determine even a partial deduction.”

CONCLUSION

In the Niyitegyeka case, because it was an undisputed fact that deductible travel did happen, it seems that had the taxpayer done a bit more work there might have been sufficient substantiation for the Tax Court to approve the deduction.

Keeping track of expenses on a regular basis can be an annoying chore. But as this case clearly emphasizes, failure to do so can be costly.
