I've used TaxAct to file my taxes and have been happy with it. My question is, if I use another program such as TurboTax, if I can increase my tax return by saving on paying as many taxes. I'm guessing that maybe another program may have more tax saving options than another. I've read several reviews on TurboTax vs another tax program and TT always came out on top, though it never covered my question in the reviews (maybe 'cause it can't).

What really brought me to this question is that I used to hear advertisements from Tax Preparers on TV (such as H&R Block...) how they could increase your tax return by around $300 vs. what the other guy can do. How can they do that? If they can claim doing that, then maybe a tax program can do the same? Who knows?
