tax and ni

[caraxx]

How do I pay tax and ni if I get paid cash in hand? do I pay at end of year for them both?

you will need to register with HMRC as self employed and will fill out a tax return every year.
keep your accounts upto date and remember to write down all your earnings.I use invoice books (one per family)from ebay that copy with carbon paper .I write on them all the hours used and how much they need to pay(I get paid in arrears)then give parent the top copy and I keep the other as proof of what I have earned .
If you have earnings above the tax threshold then you will be told what you need to pay.
you will pay NI if you earn over a certain amout(cant remember how much but its not a lot)If you have a low income you can apply for exemption .Easiest way to pay is direct debit
