Exception 2: Employers may exclude from wages any 2018 reimbursements to or payments on behalf of employees for moving expenses incurred for a move that took place prior to January 1, 2018, and which would have been deductible had they been paid prior to that date. See Notice 2018-75.
Moving expenses are deducted on Form 3903 Moving Expenses. For lists of deductible and nondeductible moving expenses, see the IRS Instructions for Form 3903.
