There is nothing special you need to do. You will still just enter your W-2 on your return as you always would.
Your return is meant to reconcile what you had withheld or paid in during the year with your actual tax liability. So, if you increased your withholdings, it is possible you may get a bigger refund or at least owe less than you would have when you were having less withheld.
Thank you for your reply. My question is how to account for the married status withholding the first 6 months. Withholding as married status is less than a single status. However when filing for 2024 as single, it doesn't account for that first 6 months and I end up owing the difference for those 6 months even though I was not single.
You will need to file a W4 form with your employer to adjust your withholdings for this current year. Please download Form W4 for the W4 and instructions in order to fill this out and submit to your employer as soon as you can.
As far as accounting for the married status for the first six months, there is no adjustment you can make for 2023. You are required to file single for the year and unfortunately, there are no allowances for life changes in the return. The only thing you could have done was to file a W4 change in 2023.
DO NOT DELAY IN FILING THIS WITH YOUR EMPLOYER IN 2024 !!
