• Medicare Tax: Unlike Social Security, there is no wage limit for the standard 1.45% Medicare tax; it applies to all earned income.
• Additional Medicare Tax: High earners (over $200,000 for individuals or $250,000 for joint filers) pay an extra 0.9% Medicare tax on income exceeding those thresholds.
• Self-Employment: Self-employed individuals pay the full 12.4% Social Security tax on their net earnings up to the annual limit.
• Senior Deduction (New for 2025): Under the One Big Beautiful Bill Act, taxpayers aged 65 and older can claim a new $6,000 deduction (up to $12,000 for couples) to reduce overall taxable income.

The Social Security Administration officially adjusts these limits annually based on the national average wage index.
