Total Schedule 1-A deductions
$15,650
saves about $1,878 in federal income tax
Married couples must file a joint return to claim the tips, overtime and senior deductions. The IRS rules for car loan interest don't list that requirement.
Your income is above at least one phase-out threshold, so some amounts are reduced. The table below shows each limit.
Two people 65 or over only fits a joint return, so we've counted one.
An estimate, not tax advice. Social Security, Medicare and state tax aren't included.

Questions people ask
Do I need to itemize to get these?
No. All four work whether you take the standard deduction or itemize.
I'm married. Can I file separately?
Not for tips, overtime or the senior deduction: those need a joint return. The IRS rules for car loan interest don't list that requirement.
