NY Part-Year Resident form and bonuses (IT-203)

Hi,

 

We left NYC August 31 2023, also part of the year I worked in CT office as a non resident. My employer withheld some tax for CT. Could you please help me how to calculate income that I need to enter as NY wages.

 

Timeline:

Jan-Aug 2023 - lived and worked in NYC, periodically visited CT office;

March 2023 - received bonus for work done in 2022;

Aug 2023 - last month of NY residency (moved to another state);

Dec 2023 - received part of the 2023 bonus (employer withheld NY tax);

 

How to calculate NY wages?

What portion of Dec 2023 bonus payment should be included in NY wages?

Since I worked in CT I will fill their form and as I understand I can deduct tax paid to CT from NY tax. What portion? All CT non resident tax or part of it proportionally days I was NY resident?

 

Thank you!
