UK Inheritance Tax Trust Reporting 2027 — What May Change

The UK government has announced a planned simplification of Inheritance Tax reporting for certain non-taxpaying trust transfers and trust events. The stated aim is to remove the need for some trustees and individuals to submit Inheritance Tax accounts where no tax is due. The government says it intends to make the change effective from 6 April 2027, but the detailed regulations and operational instructions are not yet the same thing as a final, universal exemption from IHT reporting.

This guide explains what is currently announced, what trustees should continue doing, and how the proposal differs from the existing rules for chargeable trust events.

What has been announced?

HMRC’s Tax Update 2026 says the government will simplify IHT reporting requirements for certain non-taxpaying trust transfers and trust events. The stated effect is that some trustees and individuals will no longer need to submit IHT accounts where no tax is due.

The announcement does not, by itself, provide a complete list of qualifying events, a replacement form, a new value threshold or a final test that a trustee can apply to every trust. It says regulations will be laid to make the change effective from 6 April 2027. Until those regulations and supporting guidance are available, treat the measure as an announced future administrative change rather than current law.

Which existing trust events need careful treatment?

Relevant-property trusts can have several IHT events, including transfers into trust, exits from trust and ten-year anniversaries. The tax result depends on the trust, assets, previous transfers, available nil-rate band and the event date.

HMRC’s current trust guidance says trustees may need to use IHT100 and the relevant event form when IHT is due. A non-taxpaying result does not automatically mean that no information is required: an excepted transfer or settlement can have its own conditions, and the reporting route can depend on the event and the applicable regulations.

Why the date matters

The proposed effective date is 6 April 2027. That date should not be used to retrospectively change the treatment of an earlier event, and it does not mean that every event occurring after that date will be exempt from reporting.

For a trust event near the boundary, record the date of the transfer, exit, anniversary or other chargeable event precisely. Keep the trust deed and valuation material that supports the event date. The final regulations may contain transitional or event-specific wording, so a trustee should not rely only on the date shown on a bank transfer or a later filing.

What should trustees do now?

Until the final rules are published, trustees should continue to:

• identify the trust type and the relevant IHT event;
• calculate whether IHT may be due, including earlier transfers and trust history;
• check the current HMRC guidance for IHT100 and the relevant event form;
• observe the current reporting and payment deadlines where they apply;
• retain the trust deed, asset valuations, liabilities, distribution records and calculations; and
• record which policy version or HMRC page was used for the decision.

This preparation is useful even if the future change removes a filing step. A simpler reporting route will not remove the need to substantiate the trust’s assets, beneficiaries, event date or calculation if HMRC asks questions later.

Does “no tax due” mean “no report” today?

No. The two questions are related but not identical:

1. Is there an IHT liability? This depends on the trust event and the detailed IHT calculation.
2. Must information or an account still be delivered? This depends on the current excepted-event and reporting rules.

The announced policy is specifically intended to remove some reporting where no tax is due. It does not authorise trustees to skip a current filing simply because their calculation produces zero. Use the current HMRC route until the final 2027 changes apply and say otherwise.

How this differs from trust income-tax reporting

The announcement concerns Inheritance Tax reporting. It does not remove a trustee’s separate responsibilities for trust income, Capital Gains Tax, Trust Registration Service updates or a trust and estate Self Assessment return where HMRC requires one.

For example, a trust could have no IHT due on a particular event but still have income, gains, registration changes or a separate tax return obligation. Keep the IHT checklist separate from the trust’s annual income-tax and CGT records.

What is not yet safe to publish as a final rule?

Do not rely on any of the following unless later regulations or HMRC guidance confirms them:

• a universal exemption from IHT100 for all non-taxpaying trusts;
• a specific monetary threshold for the new process;
• a new form number or online workflow;
• a rule that removes the need to calculate the event; or
• a conclusion that a trust’s ten-year, exit or lifetime-transfer obligations disappear.

The official announcement is enough to plan for a possible administrative reduction, but not enough to create a final filing decision for a particular trust.

Frequently Asked Questions

Evidence and decision checks

A reliable uk inheritance tax trust reporting 2027 review starts by fixing the tax year and the date on which the relevant event happened. Record the person's or business's status, the income or transaction category, the amount before tax, tax already withheld, and any election or claim being relied on. Do not combine a headline figure with a final liability: the result can change when another income source, a payment date, an ownership interest or a qualifying condition is added.

Keep the source documents behind every important input. Depending on the subject, that may include payslips, invoices, bank statements, contracts, provider statements, travel records, HMRC notices, payroll submissions, valuations or correspondence. Where an amount is apportioned, write down the method and retain the underlying total. If a correction is made, preserve the original figure and explain the reason, date and evidence for the replacement.

Before relying on the result, check the current official guidance for the same tax year and jurisdiction. Distinguish enacted law from a consultation, draft measure, announcement or future proposal, and record the effective date. Reconcile the final estimate to the relevant return, payroll record or HMRC account. A calculator or explanatory guide can support a decision, but it cannot replace the eligibility test or the official filing and payment process.
