Many people are afraid of filing for income taxes. But there are cases when you can make mistakes concerned with income tax. So be ready to read about these mistakes and not to do them any more.

1. You must pay the Alternative Minimum Tax (AMT). This tax was originally designed to make sure wealthy earners couldn't take advantage of so many tax breaks that they ended up paying little or no tax. Nevertheless, more people are falling into this AMT bracket. So, to see if you fall under AMT, you should calculate your taxes by regular rules and by AMT regulations.

2. You should forget to five-year average. You can take all of your money out of a qualified retirement plan. If you have done this and didn't roll it over into another retirement plan or an individual retirement plan, then you may qualify for five-year averaging. Then, you will pay the entire tax bill on the withdrawal, but calculate it as if the payout was spread out over five years.

3. Forget to include your mutual fund re-invested dividends. If shareholders won't sell their fund shares, they will have to pay taxes twice on profits. Their task is to add the dividends and gains into their original investment.

4. Demand your home-office deduction. Taxes do not have to be paid on up to $500,000 in benefit, when selling a home. However, there may be some capital-gains tax paid on the home office portion.

5. You should decide not to calculate whether to file jointly or separately. Moreover, each couple should decide this based on their own individual situations.

6. Assume you can't make more retirement contributions. You are able to have several options, in case you didn’t max out your retirement plan contributions last year. However, you can make additional contributions because there are places that your employer can make them to as well.

7. You should forget to claim carry-overs and credits. For example, you can't demand more than $3,000 in investment losses in a single year, but you can carry the unclaimed amount over into future years.

8. Overpay your social security. You may be able to file a claim on your return for excess withholding if you earned more then $72,600 working for two or more employers. This is an alternative because salaries over $72,600 are not subject to Social Security tax.

9. Fail to take gambling losses. Gamblers are allowed to deduct losses up to the amount of their winnings if they keep acceptable records of their losses.

10. Fail to do your homework. You should research and review all allowable deductions and most importantly. Try to keep good tax records.
