How long does it take for an amended Nys tax form to be processed

Plan on several weeks (or even months).

It can take up to 12 weeks from when the return was received for NYS to process and make an update about an amended return. 

Thank you 

How long did this end up taking? I have been waiting for my amended NY state return for 3 weeks so far?

To check the status of a New York amended return, see this New York webpage. They have a dedicated phone number to check on amended returns.
