yes I see the same thing in 2022 whereby I received a large refund from NY state. When I do a simple math of calc how much I paid in NY taxes vs wages for NY, I get 10.84%. So just divide W2 box 17 / box 16. When I look at the calc in turbo tax, it is using around 6.8% tax. This is resulting in a large refund. In 2022, I received a refund from NJ as well but in 2023, I had to pay taxes with a penalty. I sort of understand this as I had some additional NJ income that wasn't taxed when earned. I looked into this a bit more and what I see is that my employer is taking out about 7% for NY state tax on a per paycheck basis. However, I am in a field where there is a one-time bonus each year and when that occurs, I see my employer is withholding close to 11% for NY state taxes. I am not sure why that is. Anyway, I went in an adjusted by W4 with the employer for NY state and changed it from 0 allowances to 3. I will see if this helps.
