federal taxable income went down in 2023 but federal tax went up significantly compared to 2022

Our 2022 taxable income was 145K. Our 2022 tax was slightly less than 17K.

Our 2023 taxable income was 142K. Our 2023 tax is 21K.

 

So our taxable income went down and our tax went up significantly. I'm not of any tax law change that would account for this.   Possible explanation?
