Section 72 cover is usually whole of life cover, so it pays out whenever death comes, not only within a set term. Couples can choose joint life second death cover, which pays when the second of you dies. That matches the tax, since everything passing between spouses is exempt.
The policy must be written as a Section 72 policy from the start, and the cover must be at least eight times the yearly premium. Some providers guarantee the premium will not rise. New applicants are accepted up to age 74 with both Irish Life and Zurich.
