...I just finished a IRS audit that lasted 7 months, if I would of keep better records I would not be typing this from jail (joke)
but it would of made it a faster audit,...
The IRS can tie you up on income taxes for months when all the time they were wrong. I just finished a round with them about 2010 income taxes, receiving threatening letters in the mail, sending replys that seemed to go into a bottomless hole, finally receiving a letter saying they owed me a $26.10 refund for 2010, instead of me owing them $2,610. Of course under the laws they can change their opinion for up to 10 years after a return is filed and come after you again. On your tax return, you are assumed guilty until you manage to prove your innocence.
Our income tax system here in the US is a pathetic joke. There is no way you can predict how much taxes you will owe on April 15 (15 months in the future), yet under the laws you are REQUIRED to start in January of the previous year pre-paying 90% of what you WILL owe up to 15 months in the future, or to pre-pay in at least as much as you paid last year. Otherwise you will owe a penalty, plus interest.
As you get older, more and more of your income will (or should) come from retirement, savings, and investment income. These are totally unpredictable and depend on the state of the economy and other outside factors completely out of your control. Yet the IRS laws passed by Congress were written as if this type of income is predictable a year in advance, and you are held accountable if you guess wrong on your withholding amount. What a screwed-up system!
It helps to learn about the tax rules. I have been volunteering with AARP as a Tax-Aid Preparer to do tax returns for several years now. I have learned enough to know that the system is unfair, unworkable, and a jumbled mess created from political lobbying by various groups.
WARNING: Many of us are going to be hit by extra taxes in the 2013 tax year, due to the Alternative Minimum Tax (AMT) rules, among other increases. The AMT rates will cut into your bank account. If you haven't paid in in advance starting January 2013 enough to cover the AMT, you could be scrambling in April 2014 to come up with the unpaid tax (unless Congress passes the usual "fix" to doctor up the AMT rules to raise the AMT kick-in income level).
