Business travelers: Take note of updates to per diem rates
The IRS recently issued guidance on how businesses, self-employed individuals and qualified employees can use the per diem rules to substantiate their business travel expenses for tax purposes. The guidance in Revenue Procedure 2019-48 modifies 2011 guidance to reflect changes made by the Tax Cuts and Jobs Act (TCJA).
The per diem rules themselves haven’t significantly changed. Primarily, RP 2019-48 deletes guidance for taxpayers who, before the TCJA, were allowed to deduct certain unreimbursed business travel expenses. Here’s a refresher on what changed under the TCJA and the rules for using per diem rates.
