我搞明白了一半。

if box 1 (wages) is 230K, box 2 (social security wage) is 114K, box 3 (medicare wage) is 246K. 

pre-tax 401K is not counted in box 1, but it is counted in box 2 and 3. 

For box 3, so it is possible you have 16K pre-tax 401K contribution that is not counted in box 1 for income tax, but counted in box 3 for medicare tax.    There is no maximum wage limit for Medicare tax so 246K is 230K + 16K. 

For box 2, the maximum wage subject to social security is 160K for 2023.  I have no idea why your box2 is 114K.

• 那个数字是前几年的，所以Box2的number会少一些。 -lovecd- ♂ (197 bytes) () 04/30/2024 postreply 10:18:49
