How to Calculate Schedule 1-A Total Deduction
All four new deductions in one place — tips, overtime, car loan interest and the senior bonus.
How this number is built
Calculating it yourself
Step 1
Gather the four inputs: reported tips, qualified overtime premium, car loan interest paid, and your age.
Step 2
Apply each statutory cap: $25,000 tips, $12,500 overtime ($25,000 joint), $10,000 car interest, $6,000 per senior.
Step 3
Apply each phase-out separately — they use different thresholds and different reduction rates.
Step 4
Add the four results together; this is your Schedule 1-A total.
Step 5
Multiply by your marginal rate to see the cash effect on your refund or balance due.
What people ask next
Can I claim more than one of these?
Yes. They are independent. A 66-year-old server working overtime with a qualifying car loan could claim all four.
Do these replace the standard deduction?
No. They are additional and are available whether you itemise or not.
