At a typical 1.5% Texas tax rate, the typical win on your own takes about $250 a year off the tax bill, and you keep all of it. The typical agent win takes off about $235, and the agent keeps about $59–$94 of that. Filing is free, online or by mail, and there's no agent contract to renew or cancel each year.
