This is a really good question and I would like to hear more. My situation is similar. I lived in NYC for the first 2 months of 2020 and then moved back to my parent's home upstate. I gave up my NYC residence. But, I did not update my residence with my employer until July. So I payed NYC tax for 7 months.
I used IT-360 to calculate my owed NYC tax for 2 months. The calculated amount is significantly less than what I paid as reported on my w2.
The discrepancy is the reported NYC income on my w2 and my actual income for the 2 months I was there.
Will they believe me?
