(How) do I have to prove the allocation between home office and commuter allowance in my tax return?
I have an office job and work irregularly, sometimes from home and sometimes in the office. Depending on my workload, I can claim the home office allowance or commuter allowance on my taxes.
But how do I divide it up? Can I simply estimate the ratio and offset it against my working days? Do I have to document it myself? Do I need an "official" confirmation from my employer?
Ideally, you entered this in a calendar or the like. If you don't mind, you can appreciate it. But be careful that the total number of working days is not too high.
You do not need a certificate from the employer if the information is plausible.
How many miles do you get to work? Is there a big difference between distance pan and home office flat?
Distance pack is about twice as high for me, so a noticeable difference
No reason to deviate from the real days.
At best you entered this in your calendar as many days a year you were in the home office and how many at work. Of course, a certificate from the employer is sufficient. Your employer should have recorded your working hours.
Otherwise you can appreciate it. As long as it's plausible.
In case of doubt, however, you must prove the advertising costs if the tax office does not accept your estimate.
estimates; think that's going through when it's not too unrealistic.
