OK, I have searched the existing 529 plans, and my question is a bit more specific.
I am in New York State. NY has a state-sponsored 529 plan. Their website states that contributions up to $5k per individual or $10k per married coupled filing jointly are tax deductible on the NY state tax return. My wife and I are able to max out that contribution from liquid. This is great since NY state taxes are HIGH, and we would also save some money paying the high NYC tax. The contribution would not alter our bracket, however.
What I can't figure out is if 529 contributions are tax deductible only if I choose my state sponsored plan, or if contributions will be tax deductible to any 529 plan at all.
The follow up question being, if the former is the case, is the tax deduction worth it to choose the NY State Direct plan? Or should I shop around and choose the best 529, even if it's run by a private brokerage? I have done a little tiny amount of research that indicates that NY State Direct Plan is on the better end of 529s, but I'm not sure how to shop around for the best plan.
