Gifts you receive are not taxable income. However, money that you receive as compensation for services performed would be self-employment income and you would be required to file a schedule C to report your income, deduct business expenses, and pay tax on your net profit. It sounds like you think this was a gift, and if this is the only money you received, the IRS is unlikely to ask you about it. But if this was compensation for services performed, it would be on your honor to report it as taxable income. It doesn’t matter if you haven’t withdrawn the money to spend it. The fact that you received it in your account is enough, if it is taxable.
