I’m able to write a lot of my tools off for tax.
Doing last years tax, I got mine done with the accountant, my wife got there just as I finished, did her tax. Phew I thought, she won’t see how much I spent this year. Then the accountant said “we will just review both of them now” and brought up my depreciation tables showing all the expensive stuff from the last 5 years and the table for last year. My wife was looking at the screen with a bit of a puzzled look on her face. We got home and she said, so the stuff the accountant brought up on the screen, how do you understand it. I have no idea what it was.
I don’t ask about the baking things she buys, she doesn’t ask about tools or test equipment.
