Son lived in NY until he enlisted in Navy 8/7/14. Has been in IL, CT, GA and currently in WA where he'll be for about 4 years. Does he still pay NY state tax?

He is only in NY when he gets leave which is only about once a year.  His W2 has his total wages earned for 2016 in the "state tax" area.  Can he amend his W-2 or submit orders with it?

It depends, but he does probably still pay NY tax.  Since he is active-duty military, his state of legal residence remains what it was when he entered the Navy:  New York.  New York tax law is a bit complex when it comes to military income, but here's a website that sums it up well:    http://www.military.com/money/personal-finance/taxes/state-tax-information.html#NY.  Unless he is maintaining a residence outside of New York, New York does tax his income.  Here is an additional FAQ about Military residence:  https://ttlc.intuit.com/replies/3302301

If he is stationed in another state, he does not file a tax return to the other state, only New York.

Tip:  If he can legally establish residency in Washington state by having the DD Form 2058 accepted and processed by DFAS, he may find this advantageous.  Washington has no state income tax.
