One specific statistic got a lot of media attention this last tax season: approximately 47% of Americans would pay no federal income tax in 2009. The Tax Policy Center recently published a report explaining why so many people would be tax-free.
The first factor in so many people not  having to pay income taxes is the recession. Many people lost their  jobs, or had their pay cut as a result of the economic downturn. The  lower your income, the less you pay in taxes. If your income gets low  enough, you will not be subject to federal income taxes. 
 
The biggest factor in the high number  of people who didn’t have to pay income tax: tax credits and deductions.  The increase in deductions, credits and dependent exemptions has lowered  tax liabilities almost across the board, often low enough to remove  all tax liability. 
So, is this a good thing? A bad thing? It’s up for debate. Yes, our country is neck-deep in budget deficits, and more tax revenue would certainly help solve that issue. On the other hand, nearly every family has suffered some economic losses in the last few years, and that extra cash in their pockets goes a long way in helping stay afloat. Either way, I will be keeping an eye on this trend over the coming years to see how it all plays out.
