Companion to Tail Coverage Explained — that article covers when you need a tail; this one covers what it costs.
Tail coverage has a pricing structure lawyers rarely see elsewhere in insurance: it’s quoted as a multiple of a premium you already know, paid once, for a policy that will never renew. That makes the math easy — and the sticker shock real, because the number arrives exactly when a firm is retiring, dissolving, or merging.
The short answer
Expect roughly 150% to 300% of your final annual premium, as a one-time payment. A solo paying $3,000 a year faces a tail bill somewhere between $4,500 and $9,000; a five-lawyer firm paying $20,000 might see $30,000 to $60,000. Where you land in that range depends mostly on the tail’s duration — one year sits at the bottom, unlimited at the top — plus your claims history and practice mix. The two ways to pay less: qualify for a free retirement tail, which many carriers grant after three to five consecutive years on their paper, or avoid needing a tail at all by maintaining prior-acts continuity when the change is a move rather than an exit.
Why it’s priced this way
A tail — formally an extended reporting period — extends your right to report claims after a claims-made policy ends. The carrier is agreeing to accept future claims with no future premiums, on work already performed. All the risk, none of the renewal income — so it’s priced as a lump of the premium that risk was priced from.
What moves the multiple
- Duration. One-year tails price near the bottom of the range; three- and six-year options step up; unlimited tails sit at or past the top. Match duration to your exposure: statutes of limitation on malpractice claims run longer than most lawyers assume once discovery rules apply.
- Claims history. A recent claim doesn’t just raise premiums — it raises the base the multiple is applied to.
- Practice mix. The same practice areas that price the underlying policy price its tail.
- Timing. Tail elections typically must be made within a short window after the policy ends — often 30 to 60 days. Miss it and the option is simply gone, at any price.
The free tail — the retirement benefit worth planning toward
Many carriers waive the tail premium entirely for lawyers who retire from practice after a tenure threshold — commonly three to five consecutive years with that carrier, sometimes with a minimum age. Two planning consequences:
- Carrier-hopping has a hidden cost. Saving a few hundred dollars a year by switching resets the tenure clock — and can reset your retroactive date if handled badly. The free tail on the other side of five loyal years is often worth five figures.
- Retirement timing is an insurance event. If you’re two years from a free tail, that fact belongs in the retirement plan next to the office lease.
Don’t buy a tail you don’t need
The most expensive tail is one bought unnecessarily. Joining another firm or switching carriers usually calls for prior-acts continuity — the new policy covering your old work by honoring your retroactive date — not a tail. A tail is for genuine endings: retirement, dissolution, leaving private practice. The full decision map is here; getting it wrong in either direction costs real money.

FAQ
How much does malpractice tail coverage cost?
Typically 150%–300% of the final annual premium, paid once. Duration is the biggest variable — one-year tails price near the low end, unlimited tails at or above the high end.
Is tail coverage a one-time payment?
Yes — a single premium for the extended reporting period. There are no renewals because there is no ongoing policy.
How do lawyers get a free tail?
Many carriers waive the tail premium for lawyers retiring after three to five consecutive years on their paper, sometimes with age minimums. Confirm the threshold in writing before counting on it.
Can I decide about a tail later?
No — election windows typically run 30 to 60 days after the policy ends. After that the option expires regardless of willingness to pay.
