You must declare your revenue in compliance with the laws and requirements applicable in your country.
Please be aware of the differences in terms of laws and requirements if you are acting as a company or as an individual.
You are responsible for reporting the amount of your payouts, as required by legislation. As well, you are responsible for the income tax on any money made from Teezily campaigns.
If the profits you have received are a temporary "one off" or a small amount, Teezily invites you to contact your tax service in order to seek the possibility to declare it as an exceptional income.
