查到這個， medigap 和前2年報稅收入無關。以前上小孫班長的課，都聽過， 但是， 忘記了

Are Medigap plans based on income?

 

 

Can Medicare charge me more based on my income? Yes Medicare can but this has nothing to do with MEDIGAP. Most people only pay for their Medicare Part B premium of $174.70 per month -with Medicare Part A generally covered at no cost to you.Sep 16, 2022
