Deductions & credits

4592 or 4952?

"The IRS allows certain taxpayers to take a tax deduction for the interest expense on some loans using Form 4952. However, the tax ramifications of investment interest can be complicated, as the IRS only allows a deduction for certain types of investment interest. Additionally, the Alternative Minimum Tax (AMT) could completely disallow the use of your investment interest deduction."

 

"allows certain taxpayers..... allows for certain types of investment.... Additionally AMT..." - Is there a rational explanation for this pick and choose type of policy? I mean, there should be, it's just very complicated?
