Actually, the Tarasque is an imaginary creature in a game, so you can't actually kill it since it's not real.

:P

Joking aside, in 2e it regenerates at 1HP per round and resists/reflects lots of attacks, but you can get it to 0HP reasonably. There's even detailed information on how to harvest various treasure from its carapace once you've done so. But... "even the slightest piece of the Tarrasque can regenerate and restore the monster completely." And "slaying of the Tarrasque is said to be possible only if the monster is reduced to -30 or fewer hit points and a wish is then used."

In DnD 3.0 you had to reduce it to -30 and use a Wish spell to kill it permanently, otherwise it inevitably regenerated. The entry in the Monster's Manual states that anything else which normally would kill instead just reduces it to -10hp.

In 3.5e it has 858 hp, regenerates 40hp/round, and is pretty-hard to damage in the first place. That said, reducing it to 0hp and then administering a coup de grace is on the table; the Tarrasque gets to make its +38 Fortitude save, of course, but there's nothing like the earlier -30&wish or inevitable regeneration in its description.

In the 4th edition Monster's Manual, it's listed under Abomination, and now lives in the world's core, returning there to sleep when it reaches 0hp; there are no rules to kill it, though it is suggested that - if the Tarrasque leaves the world - it could be killed.

In 5e the Tarrasque is pretty tame by comparison: no regeneration or choice to not take full damage from an attack. That said, you need to do 676 damage against its AC25; it's immune to poison, fire, and nonmagical weapons; it reflects back ranged spells and some others. So you've got to get crawling on it with magical weapons and touch spells. Don't worry, though--if you get swallowed but your fellows manage to kill it, you can crawl out with 30' movement. So not only is it possible to kill the 5e Tarrasque, but it's been explicitly contemplated in the rules.

So it does seem to vary from edition to edition.
