As I understand it, after 59.5 years, any Roth IRA withdrawals incur no tax, provided the account is at least 5 years old. Therefore, if my only income after that age were from Roth IRA withdrawals, I would pay no income tax.
After that age, if I had additional income that was taxable, could the rate at which the additional income is taxed be affected by the amount I withdraw from the more-than-five-year-old Roth IRA that year?
