New York State Sales Tax (Aircraft) Info

All,

I am about to purchase an aircraft that currently resides in CA. I am
planning to fly it back to NY and register it in New York. I
understand that there is a 4% sales tax on aircraft registered in New
York, due at the time of purchase.

Is anyone aware of any interesting loopholes to this sales tax law? I
understand that in some states, if the airplane resides in a state
outside of the new registration state for more than 90 days, the new
owner is exempt from sales tax.

Does anyone know if this is applicable to NY, or if there are any
other options I should be considering?

Thanks,
James
