Retired workers who earn self-employment income can claim a valuable tax deduction that many overlook. Medicare premiums and long-term care insurance costs qualify as "above-the-line" deductions, meaning you can reduce your taxable income even if you don't itemize.

Here's how it works. If you're self-employed in retirement, you can deduct 100 percent of Medicare Part B and Part D premiums directly from your gross income. The same applies to long-term care insurance premiums, up to age-based limits set by the IRS. These deductions reduce your adjusted gross income before you claim the standard deduction.

The catch: You must have self-employment income to claim these deductions. W-2 retirees cannot use this break. Your net self-employment earnings must equal or exceed the insurance premiums you're deducting.

For 2024, IRS limits for long-term care insurance vary by age. Taxpayers age 40 and under can deduct up to $530 annually. The ceiling rises to $1,410 for those 50 and over. Medicare premiums carry no such caps.

Financial planners emphasize the importance of proper documentation. Keep records of all premium payments, including receipts and 1098-QC forms from insurers. When filing Schedule C (for self-employed income), you'll claim these deductions on line 29, labeled "Deductible part of self-employment tax."
