It is your responsibility to know the tax laws of your country and local area, and to comply with them.
In many countries, payments you receive from selling goods and services in the marketplace may be taxable as income.
Profits from holding or exchanging cryptocurrency may also be taxable.
Since there is no central site in OmniBazaar that processes all transactions,there is no person or company that can keep track of your transactions, profits, and income, except you.
We encourage you to know and follow the tax laws that apply to you.
