CT State Amended Filing - Part Year Resident Income Split Correction (Tax Year 2022)

Hello,

 

I'm working on an amended CT state filing for tax year 2022 where I was a part-year CT resident. I'm filing an amendment since I incorrectly allocated my wage split for the Connecticut Resident Period vs Connecticut Nonresident Period. The total wages were correct, but I was overtaxed due to an incorrect wage split between CT and a state with no income tax so I am looking to correct the wage allocation. In TurboTax, when I initiate an amended filing, it only generates a Form CT-1040X. Looking online, it appears that I won't be able to electronically file anyways, but I wanted to confirm that I am filling out the correction forms to mail in.

 

This is my understanding of what I would need to do:

1) Fill out CT-1040X (net change column B and correct amount column C)

- Line 6: Income from CT sources from schedule CT-SI (input corrected CT wages)

- Line 10,12,14,16,18,20: Corrected income tax due to the corrected CT wage allocation

- Line 27: Amount overpaid

- In addition, there's a text field for justification towards the top that I will fill out explaining why this amended filing is needed.

 

2) These don't show up in TurboTax as part of the amended filing, but my understanding is I would fill out a corrected version of the following forms with the correct wage split:

- CT-1040NR/PY (even if similar inputs to 1040X)

- CT-1040AW

- CT-SI

 

This is my first time completing an amended state filing (especially for a part-year resident), so I just wanted to make sure this was the correct process for this situation and to check if I was missing anything. Thank you very much in advance!

    You are filling everything out correctly.  You are also correct that you can't file a 2022 return electronically.  You are probably also aware (but it bears repeating) that the 2022 tax year expires on April 15th so you need to get this in the mail no later than April 14th.  

     

    Good luck!
