My mom files as a senior - married filing separately. For 2022 she filed with a W-2 around $64K and social security benefits around $ 5K -received a return of $980. Filing the same for 2023 W-2 around $59K and social security benefits around $20K plus – has to pay $1670. Other than the amounts nothing is different with her filing why she must pay this time can someone please explain the difference. I thought the standard deduction was increased. Did Turbotax calculate incorrectly by any chance?
