Edit: *personal trainer*

just started a personal training job in january of 2026. i keep records of all payments, i have to just move them from my planner onto a spreadsheet. my question is about clients who give cash payments, most that come just pay cash. often times i do not deposit it in my bank, i have three kids and normally just use it for them, or to fill up gas (i don't work with a lot of people at the moment)

how does this work come tax time for next year? I'll have money set aside for tax purposes.

1. should i be filing quartarly now?
2. best way to track cash payments? Is just keeping track of it on a spreadsheet ok?
