Are tax deductions voluntary?
What kind of "deductions" are you talking about? Many deductions, like the standard/itemized deductions, come after the AGI, and do not affect the AGI, so I don't see how this would make any difference. Maybe you are talking about deductions that come before the AGI? If you want to increase your AGI legitimately, here's a way: Every year, itemize deductions on your federal return, and over-withhold your state income tax (assuming your state has income tax) by a lot, and/or make voluntary extra payments to your state income tax. As a result, you will get a huge refund on your state taxes the following year. Then you will need to include this refund as income on line 10 of the federal return that year, which will be included in the AGI. (Of course, you will also be able to deduct a lot of state income tax paid every year in the federal itemized deductions, but those come after the AGI.)
