An $85,000 collectible sale can push Medicare Part B premiums from $203 to $528 monthly for single filers due to IRMAA rules.
A retiree selling a 1967 Ford Mustang for $85,000 faced an unexpected Medicare premium hike after the IRS classified the gain as a collectible. The $85,000 gain triggered an Income-Related Monthly Adjustment Amount (IRMAA), raising Part B premiums from $203 to $528 per month for a full year.
Collectible gains are taxed at up to 28%, higher than the 15% or 20% long-term capital gains rate for stocks. The surcharge applies if modified adjusted gross income (MAGI) exceeds Medicare thresholds, with the impact delayed by two years. Retirees near these brackets risk premium spikes from asset sales.
Installment sales may spread gains across tax years but must be structured before closing. Voluntary sales do not qualify for SSA-44 relief, leaving retirees exposed to both tax and Medicare costs.
