Get your taxes done using TurboTax

Thanks, Jack. If I'm following you, you're saying to compare box 2 on 2018 and 2019's W-2s, as well as box 3?

 

Box 2

2018 Fed. income tax withheld: $3,825 (8.9% of gross)

2019 Fed. income tax withheld: $3,243 (7.63% of gross)

 

Box 3

2018 SS wages: $42,982 

2019 SS wages: $42,523

 

If I've not made any voluntary changes since mid-2018 to my W-4, would the decrease from 8.9% to 7.63% be due to the Tax Cuts and Jobs Act mentioned earlier by Regina? Is the W-4 the relevant form to my issue?
