15% tax on $37,499 leaves you with $31,874.15 yearly income.
25% tax on $37,500 leaves you with $28,125.00 yearly income.
That's a $3749.15 difference in a single dollar of income.
If there wasn't a benefit to reducing your taxable income no one would do it, it wouldn't be heard of.
Need I say more?
Like I said, you don't understand how tax brackets work.
If your taxable income is $37,999, you do not pay 15% tax on all of it.
If your taxable income is $37,500, you do not pay 25% tax on all of it.
I'm going to use the tax table I posted before (for 2016).
After all your deductions (including the standard deduction), you are left with a taxable income. If your taxable income is $37,649, you're at the top of the 15% bracket. Your taxable income from $0 - 9,275 is taxed at 10%. So your tax liability is:
($9,275 x 10%) + [($37,649 - 9,275) x 15%] = $5,183.60
If your taxable income is $37,651 (I know it's two dollars, but it puts you in the 25% bracket), your tax liability is:
($9,275 x 10%) + [($37,650 - 9,275) x 15%] + [($37,651 - 37,650) x 25%] = $5,184.00
Forty cents difference on two dollars of income.
Again, tax brackets are marginal. Read the links above.

I'd say I know quite a bit about tax brackets considering I was in the 25% working overtime and putting me into the 35% tax bracket so I'd have to make deductions and write-offs to get me back into 25%.
I just noticed what you said here - the 35% tax bracket is for people making well over $400k a year. The 25% bracket is for people making just over $91k or less. You really must know QUITE a bit about tax brackets in order to reduce your taxable income by that much and still avoid paying AMT.
