Spring arrives March 20, but if you haven't finished your taxes, here's a chilling thought: Uncle Sam wants your numbers -- and maybe your money -- in about a month.

Don't fret. Plenty of cool heads await you online. Tens of millions file forms on the Web from their computers or mobile devices, and the number grows every year.

At irs.gov, you can use Free File if your adjusted gross income for 2014 is $60,000 or less. But what if it's higher? The Web can help you overcome America's ritual morass of paperwork.

The Big Three still dominate the many choices for those filing from PCs or mobile devices, and this year TaxACT has staked a better claim for the top spot.

Yes, TurboTax (which raised prices for certain functions) and H&R Block provide a few more niceties, but this time around, TaxACT -- ranked No. 1 by PC magazine -- is a better value even if you opt for more elaborate choices instead of its free federal version. It costs $15 for state filing, and you also can import the prior year's taxes from TurboTax and Block.

Unlike the latter two, TaxACT won't signal audit risk or offer live chat, but it could help your annual headache clear up before the last bit of snow on your front lawn has turned into grass.
