Thank you Kangaroomama, I think I would provide receipts yearly to avoid unnecessary paper work.

I never provided receipts. I had a separate account for my business and my clients transferred the money to my business account. Everything was there, who pays how much etc. Parents were already getting tax relief because I was registered and gave them my registration number.

Would families be OK. if I provide yearly receipts? And what else do I need to show them so that they know I'm an honest person and pay my taxes?

Thank you,
