I recently was hired as a Law Enforcement Officer and foresee thousands of dollars in expenses for equipment, materials and services that are required to perform my job. I also would have thousands of miles on my personal vehicle (I don't get a police car to take home) for required training. These expenses would not be paid for or reimbursed by my employer. Am I understanding correctly that under the TCJA I am not eligible to deduct any of these expenses, and therefore I should not track receipts/mileage? Or should I still track them for use in determining AGI (I saw it suggested somewhere)? Or am I completely off base?
