At one time not so long ago you could deduct the difference between the federal rate and the employer’s rate (they are not obligated to pay the federal rate).
Suffice to state that many are getting screwed.
Yeah, that all went away with the “Tax Cuts and Jobs Act” at the start of 2018.
I used to get a monthly car allowance but always drove over. Good paying job so I just wrote off the difference in mileage, meals and tools.
Technically it may come back in 2025 ...
