Mid-2026 UHNW Briefing: US Tax, UK Rules and PPLI

Four developments deserve separate review in 2026: the introduced Senate PPLI bill, enacted US tax changes, the UK's residence-based tax rules, and private wealth-migration research. They have different legal status and evidential weight. This midyear briefing, updated in September, explains what each changes and which family records are needed before acting. A proposal is not enacted law, a migration forecast is not a measured outcome, and a policy's tax treatment does not automatically travel with its owner.

The Senate PPLI proposal: check the bill and its status

Senator Ron Wyden introduced S. 4279, the Protecting Proper Life Insurance from Abuse Act, on April 13, 2026. The official bill-status record checked September 16 lists introduction and referral to the Senate Finance Committee on that date and contains no enactment entry. Introduction establishes neither passage nor a reliable probability of passage. The Senate PPLI proposal analysis examines the introduced definition, proposed tax consequences and transition terms.

An introduced bill does not itself amend the treatment of a contract. Current reviews still need section 7702 qualification, section 817(h) diversification testing and the ownership analysis illustrated by Revenue Ruling 2003-91. Separately, record how proposed changes could affect the actual contract if enacted. Current compliance is not a promise of future grandfathering.

US tax changes: calculate the effect on the actual taxpayer

The 2025 law commonly called OBBBA is Public Law 119-21, approved July 4, 2025. Under section 2010(c), the federal basic exclusion amount is USD 15 million for 2026, with inflation adjustments after 2026. The provision has no scheduled sunset under current law; Congress can still change it. It is not a fixed USD 15 million amount for every future year.

A household net-worth figure is not an estate-tax calculation. Prior taxable gifts, ownership, includible assets, deductions and available credits matter. Two spouses do not automatically have one unrestricted USD 30 million allowance, and there is no general USD 40 million household threshold below which review becomes unnecessary. A deceased spouse's unused exclusion generally requires a valid portability election; the IRS estate-tax FAQs explain the filing framework. State-law exposure requires its own calculation.

Itemized deductions and QSBS need their own dates

From tax years beginning after December 31, 2025, section 68 reduces otherwise allowable itemized deductions by 2/37 of the smaller of those deductions or the positive excess of taxable income before those deductions and this limitation over the start of the 37% bracket. Other deduction limits apply first. The 35% shorthand describes the regular federal tax benefit of a fully affected deduction against 37% income; it is not a universal deduction rate.

For qualified small business stock, section 1202 distinguishes acquisition dates, issuance dates, holding periods and other conditions. Qualifying stock acquired after July 4, 2025 can use 50%, 75% or 100% exclusions after three, four or at least five years. A sale occurring in 2026 does not by itself qualify for the new regime. The OBBBA planning review covers the limits and compares policy economics separately.

UK rules: separate FIG eligibility from inheritance tax

HMRC confirms that the four-year Foreign Income and Gains regime replaced the remittance basis on April 6, 2025. Broadly, it applies to qualifying UK residents within their first four resident tax years after at least ten consecutive nonresident tax years. Relief requires a claim for eligible income or gains. The November 2025 Budget discusses the implemented non-dom reforms; it does not make future amendments impossible. Migration estimates are discussed separately below and do not establish the reforms' causal effect.

Under HMRC's 2026 FIG helpsheet, unused years cannot be carried forward. Someone whose first resident tax year was 2022/23 could have only 2025/26 remaining within the four-year period, assuming all eligibility conditions are met. Being a recent arrival does not establish a new four-year window in 2026. Claims can also remove specified allowances, so compare the full return consequences before claiming.

Leaving the UK and qualifying for FIG are different questions. Under HMRC's long-term-residence guidance, the general inheritance-tax test looks for UK residence in at least ten of the twenty tax years immediately before the relevant tax year, with special and transitional rules. The departure guidance explains that exposure can continue for three to ten tax years after leaving, depending on residence history and applicable rules. A move does not automatically end UK inheritance-tax exposure.

Insurance needs a separate UK review. HMRC's personal portfolio bond guidance describes an annual charge where the PPB rules apply. Continuing the same policy contract after moving does not guarantee continued tax deferral. Review the benefits, investment-selection rights, issuer servicing permissions and local treatment before premiums, transfers or withdrawals. The insurance-jurisdiction guide organizes those questions; it does not certify portability.

Migration estimates and competitiveness scores measure different things

Henley & Partners' June 24, 2025 release projected 142,000 millionaires relocating internationally in 2025 and the country net flows shown below. Its global migration series identifies 2025 as provisional and uses relocation lasting more than six months. These figures are private research estimates, not a verified final census of moves, and net flows are not total departures.

Henley's June 16, 2026 report release introduced a different measure: a competitiveness framework using 12 dimensions and 38 weighted indicators. It reports scores out of 100 of 85.3 for the UAE, 79.5 for Singapore, 75.8 for New Zealand and 74.3 for the Cayman Islands. It places the UK, Germany and France among jurisdictions under pressure. These are the publisher's assessments, not counts of migrants, tax opinions or insurer ratings. Our wealth-mobility and PPLI-portability review explains the methodological distinction.

The planning implication is conditional: if a move is under consideration, test it against the actual assets and obligations. The scores do not establish that every family maintains relocation capacity, that one country is universally preferable or that advance structuring always preserves wealth. A policy that remains in force can still face different tax, investment or servicing rules after a change of residence.

A practical second-half review sequence

Build the review around actual decisions and dates. A pending sale, planned move, premium payment or filing deadline determines the sequence. Legislative monitoring belongs alongside current compliance. It does not replace it. The working list below is a proposed review method, not evidence that every wealthy family has the same needs or should reorganize its assets.

1. Review existing insurance: reconcile the contract, funding, investments, control rights and available compliance records with current requirements. Keep any proposed-law scenario separate.
2. Recalculate US inputs: confirm available estate exclusion, prior transfers, QSBS acquisition and issuance records, and deduction limitations. Compare after-tax cash flows and policy costs.
3. Establish the UK timeline: document residence years, any FIG claim, the income or gains involved and possible inheritance-tax exposure after departure.
4. Test a prospective move: use a hypothetical twelve-month planning horizon to identify documents and decisions. That horizon is an exercise, not a legal deadline or proof that a move can be completed in time.
5. Assign actions: record which adviser or institution must resolve each issue, the evidence required and the relevant deadline before implementing transfers.

Keep a single decision record for each action: the owner, the relevant law, the date, supporting documents, alternatives considered and unresolved issues. Obtain the appropriate legal or tax advice before implementing a change. Migration research may help frame questions, but it cannot determine the tax result, required coverage or suitability of a particular policy.
