I am 65 (and was at the end of the year), my income for the year was under 12k, and it says the new enhanced senior deduction won't affect my taxes? Why?

From what I can see I qualify and I am filing single, but it is only giving me my standard deduction plus additional deduction for my self-employment expenses (totaling 17K), so I still have federal due of $616 and I thought the new senior deduction would have been added and reduced what I owe and or helped to give me a refund

If you are filing as Married Filing Separately you are not eligible for the deduction.  If you are Single and your AGI is over $175,000 or Married Filing Jointly and your AGI is over $250,000 you are not eligible for the deduction.

If you are age 65 or older and meet the requirement, the additional deduction is automatically added on your federal tax return.

Standard deductions for 2025

Single - $15.750 add $2,000 if age 65 or older
Married Filing Separately - $15,750 add $1,600 if age 65 or older
Married Filing Jointly - $31,500 add $1,600 for each spouse age 65 or older
Head of Household - $23,625 add $2,000 if age 65 or older

New Bonus Standard Deduction (OBBB):
An additional $6,000 deduction for taxpayers 65 and older.
This is per eligible individual, meaning a married couple both over 65 could get $12,000.
Important: This bonus deduction is temporary, lasting from 2025 through 2028.
Income limitations: It phases out for taxpayers with modified adjusted gross income over $75,000 for single filers and $150,000 for joint filers.

The amount is calculated on Schedule 1-A, Part V, with that amount flowing to Form 1040 Line 13b

@DoninGA has provided a good explanation but let me expand on why you owe tax and why the senior deduction did not make a difference.

Since your income was under $12,000, your taxable income for Income Tax purposes is effectively zero which aligns with @DoninGA explanation. Adding more deductions (like the $6,000) doesn't help because you can't reduce your income tax below zero because it is already zero due to the standard deduction.

The $616 is "Self-Employment Tax", which is different from your income tax. Deductions like the Standard Deduction or the new Senior Bonus only reduce Income Tax. They do not reduce Self-Employment tax.

SE tax is roughly 15.3% of 92.35% of your net profit. If your net profit was around $4,300–$4,500 after your $17k in expenses, that would result in a tax bill of exactly about $616.
