How to address unknown tax burden
For the last three tax years, my wife and I (who file married, jointly with one dependent) have owed taxes at tax season. The initial two years we owed roughly 2-3k. During tax season last year, I spoke directly with a Turbotax representative to figure out the issue. Their opinion was that we needed to redo our W-4s to adjust our tax our respective tax withholdings so we would overcontribute and receive a return for the 2024 tax year. We both followed his advice which was to remove the dependent on our W-4s. However, this year we owe almost double what we owed the previous two years (between 6 and 7k this year). How do I actually figure out what the issue is? Is there a way to assess which one of our jobs is not withholding the desired amount? I've tried using the IRS withholding calculator but it only seems to provide a recommendation on what to withhold in the future.
