@birdatiel31 , it is not essential that you have a tax form from the payor -- all you need is something from the payor that shows how much they paid you and for what. For example in the USA , a contractor/consultant may bill for services and get paid -- the invoice and the corresponding payment ( check or direct money transfer ) is sufficient to withstand an IRS audit ( if ). So whatever official or semi-official document ( showing the payor and payee., the date and amount ) that you can get to back-up your claim of the amount earned is good enough. Note that you are getting this for the "if come, may be " case -- generally IRS does not challenge income statements but there is always the odd case.
Good luck
