See the Related Link below this answer. Agreeably, you may have to try and figure a way to relate number of families to number of returns. There are only 2 tax brackets and all the lower one would be in the < $30,122 category here..in fact many of that category aren't even counted as stated below. So about 1/3 of the returns are not just in the low bracket but NO bracket and don't pay but may even get money back. The IRS data in the link to the left include all of the 130 million tax returns filed in 2004 that had a positive AGI, not just the returns from people who earn enough to owe taxes. From other IRS data, we can see that 89 million of the tax returns came from people who paid taxes into the Treasury. That leaves 43 million tax returns filed by people who used exemptions, deductions and tax credits to completely wipe out their federal income tax liability. Not only did they get back every dollar that the federal government withheld from their paychecks during 2004; but some even received more back from the IRS. This is a result of refundable tax credits like the Earned Income Tax Credit, which are not included in the aggregate percentile data here. The Tax Foundation is a wonderful, non biased, non political very well respected group that compiles a huge amount of reliable information on taxes of all sorts. See the Related Links below.
