Hey there, @Taki -
For filing information, I would consult a tax professional. If you have over $20,000 in card payments and over 200 credit card transactions, a 1099-K Form will be generated and sent to the IRS for your account. If you don't reach the thresholds, you will have to consult a tax professional on that as well.
Please let me know if you have any other questions.
