看这两段：

According to the IRS, changes in circumstances that can affect the amount of your premium tax credit include increases or decreases in your household income. Social Security benefits are counted as income in determining eligibility for premium tax credits in the Marketplace.

Paying your medical insurance premiums in pre-tax dollars instead of after-tax dollars will reduce the total amount of your taxable income. This means less money will be withheld in Social Security and income taxes.

我是晕的。不是很懂具体，比如我用的tax credit 是不是就是 pre-tax dollars...

• 这句话， 我理解你用税前的工资付医疗保险了， 那么你交的社安税就低了， 当然， 你今后的社安金就会低点 -螺丝螺帽- ♀ (409 bytes) () 12/19/2023 postreply 14:13:22
