generally its 3-5 years afterwards...
most likely its 5.

But its cheaper to buy a new CO2 tank than to get it rehydroed, unless you live right near a place that will do it cheap.

hydro date should be stamped on the top of the tank. i think all CO2 are 5 year (unless smaller than a 9oz?) so look at the date (month:year) and go five years past and thats your rehydro date

chrommoly tanks and alluminum with a diameter less than 2 inches never need testing
