IRS denies business deductions

IRS denies dental business deductions lacking substantiation. Two married dentists were largely denied deductions above amounts the IRS allowed for office and marketing expenses related to their dental practice. The couple claimed that ink on receipts had faded due to age or water damage, and instead offered credit card statements to substantiate the disputed items. However, those statements didn’t show the full amount of charges being claimed. Also, the doctors failed to prove that multiple expenses weren’t for nondeductible personal items. (TC Memo 2017-34)
