I am an individual tax resident (not a company) and I sell software online (I don't have any contracts with clients). Can you please recommend to me what documents I should submit. My situation: I make a piece of software similar to a wordpress plugin, and I sell it from my website. All of my customers make a $25 payment that is processed through Paypal. I do over 1000 sales a year, and I transfer the money from Paypal to my New Zealand bank account. I pay tax in New Zealand as an individual , not as a registered company.

I can submit these documents:

*My website info

*My Paypal summary of sales

*My tax return

*My bank account showing the income from Paypal

Is there anything else I should submit?
