A 1% excise tax, a quarterly return, and a trust nobody meant to create

Two clocks on a dark wall showing different hours, illustrating Life insurance in trust and US tax
Writing a policy in trust is standard British planning. For an American paying the premiums, it can add an excise tax, a quarterly return and a foreign trust to report.

An adviser recommends writing the life insurance policy in trust. It is sensible British planning: the payout sits outside the estate, so inheritance tax does not reduce what reaches the family. Nobody mentions Form 720, because in a British conversation there is no reason to.

For an American paying those premiums, three separate American rules can engage. An excise tax on the premium, quarterly reporting of it, and possibly foreign trust reporting for the trust itself.

None of that makes the planning wrong. In our practice it simply means the cost is different from the one the adviser quoted, and the paperwork is heavier.

What is the excise tax on premiums?

A federal charge on premiums paid to insurers outside the United States. It applies to the premium rather than to any payout, and it falls due quarterly. Form 720 is the return that carries it.

Who actually has to pay it?

Whoever pays the premium. The instructions to Form 720 state that the person who pays the premium to the foreign insurer, or to any nonresident person such as a foreign broker, must pay the tax and file the return.

The instructions go further. Failing that, any person who issued or sold the policy, or who is insured under it, is required to pay and file.

So the obligation follows the money and then, if necessary, the policy. An American insured under a British policy cannot assume it is somebody else's problem.

How much is it, and how often?

One percent on life insurance and annuity premiums, with the rates set out on the form itself, so an annual premium of £2,000 produces about £20 of tax. However, Form 720 is a quarterly return, so that single payment still lands in one specific quarter with its own deadline.

The frequency is what surprises people. Form 720 is a quarterly return, so a single annual premium still lands in one specific quarter with its own deadline.

Small tax, disproportionate administration. That combination is why the charge is so often missed entirely.

Does the treaty remove the charge?

It can, and the treaty covers this tax expressly. The taxes-covered article of the US-UK treaty lists the federal excise taxes imposed on insurance policies issued by foreign insurers among the taxes it applies to, which is unusual for an income tax treaty.

That is unusual. Most of the treaty deals with income tax, and this is not an income tax at all.

Claiming the benefit is not silent, though. The Form 720 instructions require insurers and reinsurers taking a treaty position to disclose it annually, reporting the exempt premiums.

In practice the insurer's own status drives the answer, so ask the insurer whether it treats premiums from US persons as treaty-exempt.

Why does writing it in trust matter?

Because a trust is a trust, and the trustees are British. Consequently the arrangement falls into the foreign trust category for American purposes, with the reporting that follows. Whether reporting actually applies then depends on who is treated as owning it and who receives from it.

Whether reporting actually applies depends on who is treated as owning the trust and who receives from it.

An American who set up the trust and pays the premiums is the obvious candidate for ownership treatment.

Our article on Form 3520 and foreign gifts sets out the neighbouring reporting most families meet first.

Is the payout taxable?

Generally not, as income. Publication 525 sets out the ordinary position that life insurance proceeds paid by reason of the insured's death are not included in income. That rule assumes the contract qualifies as life insurance under the American statutory definition rather than the policy's own label.

That rule assumes the contract is life insurance for American purposes, which uses a statutory definition rather than the label on the policy.

Most straightforward term assurance looks like life insurance under either system. Investment-linked policies are where the question gets real.

Where a policy might not qualify, the consequence is annual taxation of the growth inside it rather than a tax-free payout.

What about investment bonds and whole-of-life policies?

These need individual advice, and we will not generalise about them here. A UK investment bond is a life policy in form and an investment product in substance, which is exactly the fact pattern the American definition tests.

Britain taxes those products on its own basis, with chargeable event gains and top-slicing relief.

Neither system's treatment predicts the other's. Where a policy has an investment element, get it reviewed before you buy rather than at maturity.

Does inheritance tax planning still work?

On the British side, yes, and that is the point of the arrangement. A policy written in trust pays to the trustees rather than into the estate, so it is not reduced by inheritance tax on the way to the family.

HMRC's guidance on trusts and Inheritance Tax sets out how the regime treats trusts more generally.

The American consequences do not undo that benefit. They sit alongside it as extra cost and extra paperwork.

So the planning usually survives the analysis. It just needs pricing honestly, including the filings.

What if the premiums come from a UK account?

The source of the money does not change who pays the premium for these purposes, so an American paying from a British current account remains the person paying it. What the account does affect is your other reporting, because its balance feeds the FBAR threshold alongside everything else.

What the account does affect is your other reporting, because balances feed the FBAR threshold.

Our comparison of Form 8938 and the FBAR covers those separate obligations.

Who is the policyholder, and does it matter?

It matters a great deal. Where a non-US spouse owns the policy and pays the premiums from their own funds, the American exposure narrows considerably. That is not artificial planning but a question of whose policy it actually is, and it is best settled at the outset.

That is not artificial planning; it is a question of whose policy it actually is.

Decide it at the outset, because changing ownership later can itself be a reportable event.

In our practice this single question resolves more of these cases than any treaty argument.

Group life cover through an employer

Group life cover through an employer — life insurance
From our guide to Life insurance in trust and US tax.

Employer-provided death in service cover rarely raises the premium charge for the employee, because the employer pays the premium.

The British side has its own treatment, and cover written under a registered scheme sits differently from a standalone policy.

Check whether a lump sum would pay into a trust and who the beneficiaries are. That is where an American employee's reporting question can reappear.

What happens on a claim?

The trustees receive the money and then decide what to do with it. For a beneficiary who is American, a payment from the trust is a distribution from a foreign trust.

So the payout can be free of income tax and still reportable when it passes on.

That sequence catches families at the worst possible moment, which is a reason to map it in advance.

Our article on UK inheritance tax for Americans covers the estate side of the same planning.

Does a mortgage protection policy count?

Usually yes, because it is still life insurance issued by a foreign insurer. Lenders often arrange cover alongside a mortgage, and the premium may be collected with the monthly payment.

Consequently the premium charge can apply to a policy you barely think of as insurance.

Check the paperwork rather than the direct debit description. Where the insurer sits outside the United States, the same questions arise as for a standalone policy.

Critical illness and income protection

These are not life insurance, though they are often sold alongside it in the same conversation. The excise tax provisions distinguish between categories of insurance, and the rates on the form differ accordingly.

Additionally, a payout under a health or disability policy raises its own income question, which is separate from the life cover analysis.

So a combined policy may need splitting between its elements. Ask the insurer for a premium breakdown, since one rarely appears on the schedule.

In our practice bundled protection products are the hardest to analyse and the most commonly sold.

What records should you keep?

Three things, kept together in one folder. The policy schedule showing the insurer and the country it sits in, the annual premium statements, and any correspondence about treaty treatment. Add the trust deed to them where a trust is involved, since the deed answers the reporting question.

Furthermore, keep the trust deed with them if a trust is involved. The deed decides the reporting question that the policy paperwork cannot answer.

Typically that folder is thin and it answers everything. Rebuilding it a decade later, after an insurer has merged, is considerably harder.

A short summary

Four questions settle this: who owns the policy, who pays the premiums, where the insurer sits, and whether a trust holds it.

Answer those and the filing list falls out. The tax is small. The admin is not.

Do it before the first premium. It is much harder later.

Getting life insurance right, step by step

Work through this before signing the application, not after the first premium.

  1. Establish who will own the policy and who will pay the premiums.
  2. Ask the insurer whether it treats premiums from US persons as exempt under the treaty.
  3. If the charge applies, diary the quarterly Form 720 deadlines rather than annual ones.
  4. Check whether the policy has an investment element, and have it reviewed if so.
  5. Decide whether a trust is genuinely needed for the British objective.
  6. If a trust is used, work out who is treated as owning it for American purposes.
  7. Map what happens on a claim, including who receives the money and when.

An illustrative example

Take an illustrative arrangement. An American in Bath takes out £500,000 of term assurance with a UK insurer, premiums of £900 a year, written in trust for her children.

The premium charge, if it applies, is around £9 a year. The quarterly return that carries it is the real cost, along with establishing whether she is treated as owning the trust.

The death benefit itself should not be taxable income. The figures are illustrative; the imbalance between a trivial tax and substantial administration is the point.

Common mistakes we see

First, assuming a small excise tax means no filing. The return is quarterly whatever the amount.

Second, treating a treaty exemption as automatic rather than as a position to establish. Third, overlooking the trust entirely because it holds only a policy.

Fourth, buying an investment-linked policy on British advice alone. Fifth, discovering the beneficiary reporting only when a claim is paid.

How US UK Tax Hub helps with life insurance in trust

We look at four things: who owns the policy, who pays, whether the insurer claims treaty treatment, and whether a trust brings reporting. Those answers decide whether this is a footnote or a project.

Our US federal return service covers the excise return and any trust forms alongside the annual filing, so nothing sits in a gap between advisers.

Questions this raises for readers

There is an excise tax on premiums paid to foreign insurers, at 1% for life insurance and annuities, reported on Form 720. The instructions place the obligation on the person paying the premium, and failing that on anyone who issued or sold the policy or is insured under it.


Form 720 is a quarterly return, so an annual premium still falls into one specific quarter with its own deadline. That administrative frequency, rather than the tax itself, is what makes the charge burdensome. Many people discover it years later, having paid premiums without filing anything.


Possibly. The treaty's taxes-covered article expressly includes the federal excise taxes on insurance policies issued by foreign insurers, which is unusual for an income tax treaty. The Form 720 instructions require insurers taking a treaty position to disclose it annually, so ask your insurer how it treats US policyholders.


It can add foreign trust reporting, because British trustees and an English law trust put the arrangement in the foreign category. Whether reporting applies depends on who is treated as owning the trust and who receives distributions from it. The British inheritance tax benefit itself still works.


Life insurance proceeds paid because of the insured's death are generally not included in income, as Publication 525 sets out. That assumes the contract qualifies as life insurance under the US definition. A payment onward from trustees to an American beneficiary is separately reportable as a trust distribution.


Have it reviewed individually before buying. An investment bond is a life policy in form and an investment in substance, which is exactly what the American definition tests. Britain taxes those products through chargeable event gains, and neither system's treatment predicts the other's.
