If you’ve done your taxes and there’s an amount in box 45 for Alternative Minimum Tax (AMT), then you should read this because it might help. If the box is blank, you don’t have to bother with this post.

Also, this post is going to be a little more geeky and technical. If you’d like a basic introduction to AMT then you might want to check out my AMT for Dummies post first: http://robergtaxsolutions.com/2011/03/the-alternative-minimum-tax-for-dummies/

Now for the geeky part:

AMT is a pretty sneaky little tax. A lot of the issues with AMT revolve around what goes on your Schedule A-Itemized Deductions form. If you do your own taxes you can go in and play with the numbers to see what I mean. Let’s say that your real estate taxes were $4000. If you go into your tax software and change that number to $2000 or $6000, your final tax bill will probably stay the same. The AMT will rise and fall to adjust to the regular tax change. (Make sure you put your real estate tax number back to where it belongs.)

You can’t lie about what you put on your tax return, but sometimes you can choose which deductions you want to take. You may take a deduction for the state income tax that you pay on your wages, or you can take a deduction for the state sales tax that you pay. In most cases, the state sales tax is a smaller deduction, but if you’re using a computer program the computer will always choose the bigger deduction for you. The AMT can make your bigger deduction worthless, so in this case you want to take the smaller one. Why? First, if you claim sales tax instead of income tax as a deduction, you won’t have to pay income tax on your state tax refund next year. Second, in some states, like here in Missouri, although you can’t claim a deduction for your income taxes paid, you can claim a deduction for your sales tax that you paid.

So, the bottom line is you’re not changing what your total federal tax is. You are preventing taxable income on next year’s return and potentially reducing state income tax. For some people, this will do nothing at all because it depends upon your state.

The other category that has room for movement is your miscellaneous deductions; they wind up on line 27 of your Schedule A. For the most part, this includes your Form 2106 Employee Business Expenses. If you’re in the AMT category, you’ve already been dinged pretty hard by the 2% rule, because to claim a deduction here your expenses have to be more than 2% of your adjusted gross income. The AMT is like a double shot – first you lose part of the deduction due to the 2% AGI rule, and then the AMT takes the rest of the deduction away. A lot of people with AMT don’t even bother claiming their employee business expenses because of it. But don’t forget your state income tax return. Here in Missouri, your Schedule A deductions still carry through to the state tax return so you really should include your deductions even if they don’t help your federal return.

A suggestion for AMT payers with employee business expenses: If you’re in a sales position, or any job that has high employee business expenses, and you’re in a position to negotiate a salary increase. You might want to toss in having your business expenses reimbursed. Let’s say for example that you make an annual salary plus commissions of $200,000 a year and you average $10,000 a year in employee business expenses. You put those expenses on form 2106 and after the AGI limitation you only get a $6,000 deduction for it. (200,000 x 2% = 4,000. $10,000 – 4,000 = 6,000) But once you add AMT in there, your $6,000 is worth nothing.

So, by having your employer reimburse your business expenses on an “accountable plan” (that means you submit expense reports for your mileage and meals and stuff) then that money comes to you tax free. It’s a win/win for you and your boss: $10,000 tax free income to you and a $10,000 business expense write off for your employer.

Think about it, what would you rather have; a $10,000 pay raise that you have to pay state and federal income tax on or a $10,000 tax free reimbursement on money that you already spend anyway? I thought so.

AMT is a hard tax to manage. These little tips barely make a dent, but there’s not much there to work with. Hopefully it’s been some help to you.
