Who we help

Trust and estate specialists across two tax systems

Managing trusts and estates across both the US and UK tax systems requires specialist expertise. We prepare the trust returns, estate and inheritance tax filings, and beneficiary reporting that both jurisdictions require.

US-UK Trust & Estate Tax Specialists

Managing trusts and estates across both the US and UK tax systems is highly complex. Families with international assets face strict reporting rules, estate and inheritance tax returns in two countries, and filing duties for trustees and beneficiaries that require specialist cross-border expertise.

At US UK Tax Experts, we prepare trust returns, estate tax filings and gift tax reporting, so every form reaches the IRS and HMRC complete and on time. Getting the reporting right is what helps families avoid penalties and costly mistakes.

Our dual-qualified tax accountants work with families, trustees, and executors to prepare cross-border reporting, claim relief from double taxation on the returns, and keep both sets of filings consistent year after year.

How an engagement runs

Two authorities, one file. Here is what working together actually looks like.

  1. Review

    We look at both sides together: what you file, where, and what has already been filed or missed.

  2. Position

    We set out the treaty position and reliefs that apply to you, with the numbers behind each option.

  3. File

    We prepare and submit to the IRS and HMRC, keeping the two sets of filings consistent with each other.

  4. Keep current

    Two tax calendars means deadlines all year. We track them and tell you before they arrive.

Questions we are asked most

The ones that come up in almost every first conversation with this group.

Most UK trusts are, and that classification brings its own reporting regardless of whether any US tax is due. The tests turn on court and control rather than on where the trust was written, so a trust drafted entirely in the UK can still sit inside the US regime.

Potentially a great deal. Distributions to a US beneficiary become reportable, and accumulated income can be taxed under rules that add an interest charge for the years it was held back. The reporting starts from the year of the move, so the trust's records need to be in order from that point.

They are separate systems with different thresholds, different reliefs and a separate treaty between them. An estate can be exposed to both. Relief is usually available, but it is not automatic and depends on how assets are held and where the deceased was domiciled.

Usually, provided the reporting is done properly and on time. The penalties in this area are driven mainly by missed filings rather than by unpaid tax, which means the risk is largely administrative and therefore largely manageable.

It can. A trust with a US settlor may be treated as a grantor trust, taxing the settlor on trust income personally, and the position can change on their death. The treatment is best confirmed rather than assumed, because the reporting differs substantially either way.
