📋 The $6,000 senior deduction is not automatic. It requires a MAGI calculation, a new form (Schedule 1-A), and if you are married, a joint return. Married Filing Separately disqualifies you entirely.
That last part generated a lot of questions when I posted this a month ago. Several readers couldn't find a clear answer. The law is explicit: no joint return, no deduction. Full stop.
The Social Security taxation point also drew some debate. The 85% taxable threshold applies to combined income (AGI + nontaxable interest + half of SS benefits) above $34,000 single or $44,000 joint. Not total income, not SS income alone. Combined income. The framing matters for the math.
The car loan interest deduction is real but limited. It applies to new vehicles assembled in the U.S., phases out above $100,000 AGI for single filers and $200,000 for joint filers, and caps at $10,000 in interest. On a $40,000 loan at 7%, that is roughly $2,800 in year-one interest. Deductible.
The RMD piece is underrated. A QCD (qualified charitable distribution) lets you satisfy up to $108,000 of your RMD directly to charity. It counts toward the RMD, reduces your adjusted gross income, and keeps that income out of the IRMAA and Social Security taxation calculations.
Tax season closes April 15. If any of these apply to your return, now is the time to check.
