Before You Prune: Making Sense of an Inherited Portfolio in 2026
Few financial events are as awkward as inheriting a ready-made portfolio. The paperwork arrives alongside grief and administration, and with it a quiet pressure to do something decisive: either leave every holding untouched as a mark of respect, or sell the lot before the next market headline. Neither impulse is a plan. For UK investors, the more useful first move is usually a decision about process — how to stabilise, understand and then replant inherited capital — rather than a decision about individual tickers.
Separate the estate from the portfolio
Before any investment question can be answered, the legal one must be. Executors need authority before assets can be sold or transferred, and probate can take months rather than weeks. During that period, valuations are being fixed for inheritance tax and for the eventual capital gains base cost. Trading prematurely can create avoidable complications, particularly where holdings are held in paper form, in a nominee account with an outdated mandate, or inside a pension with named beneficiaries who need to be confirmed.
The practical point is simple: an inherited portfolio often spends its first season in a holding pattern. That is not a failure of strategy. It is the correct interim state while title, valuations and tax positions are established.
The tax canvas is not blank
UK capital gains tax generally gives assets acquired on death a base cost equal to their probate value. In plain terms, the gain that accrued during the deceased's lifetime is usually wiped out for CGT purposes, and future gains are measured from the date-of-death valuation. That uplift is a meaningful planning feature, but it is not a licence to sell everything without thought. Later gains still count, the annual exempt amount is modest relative to many portfolios, and the interaction with income tax, estate administration and wrapper rules needs care.
Spouse-to-spouse transfers are another area where the mechanics matter. An ISA can generally be transferred to a surviving spouse through an additional permitted subscription, preserving the tax shelter rather than forcing a sale and re-subscription. Pensions may offer dependant or beneficiary drawdown, and a spouse or dependant may be able to continue tax-sheltered investment rather than encash at once. Other beneficiaries may face income tax on withdrawals, so the death-benefit options should be checked before any instruction is given.
These are not reasons to delay indefinitely. They are reasons to establish the tax position before the portfolio is disturbed.
Stabilise before you strategise
A sensible early step is to identify immediate cash needs. Are there inheritance tax payments, funeral costs, outstanding debts or professional fees to meet? Does the inherited portfolio provide income that someone now relies on? Is there an emergency reserve outside the invested assets? If cash is needed soon, it should come from the least disruptive source — often cash or short-dated holdings — rather than from a rushed sale of long-term growth assets.
At this stage, the aim is not to optimise. It is to prevent a temporary administrative problem from becoming a permanent portfolio decision. A short holding pattern is not a strategy, but it is often the right interim strategy.
Audit what you actually own
Inherited portfolios are rarely tidy. One may contain a cluster of direct shares from a former employer, several funds bought over decades, an old with-profits policy, a self-invested personal pension and a handful of certificates in a drawer. Another may look diversified by fund name but hold the same dozen global companies beneath the labels.
The audit should look through the wrapper to the underlying exposure. What is the split between equities, bonds, cash and property? How much is concentrated in one company, sector or currency? What charges are being paid, and to whom? Are there guaranteed pension terms, exit penalties or legacy platform arrangements that would be expensive to disturb? Are any holdings unquoted, illiquid or difficult to value?
This is also the moment to gather statements, valuations and cost records. A simple spreadsheet is enough. The goal is not to become an amateur fund analyst; it is to replace inherited assumptions with a clear picture.
Match the portfolio to your own written policy
An inherited portfolio reflects someone else's time horizon, risk tolerance and tax position. Yours will differ. If you already have a written investment policy, compare the inherited holdings against it: asset allocation, liquidity, income needs, concentration limits and wrapper placement. If you do not have one, write it now. A short document setting out purpose, time horizon, risk capacity and rebalancing bands is more valuable than a long list of favoured funds.
Sometimes the inherited holdings are perfectly sound but sit in the wrong wrapper. Sometimes they are too concentrated for anyone's policy. Sometimes they are conservative when the beneficiary needs growth, or growth-oriented when the beneficiary needs income. The policy gives you a neutral test. Without it, every sale feels like a judgment on the person who died.
Replant in stages
Once the audit and policy are in place, the replanting can begin — usually in tranches rather than one dramatic transaction. Sell clear misfits first: concentrated positions, high-cost legacy funds, holdings that duplicate existing exposure, and anything too illiquid for the plan. Use capital gains allowances and loss harvesting where appropriate, and consider moving assets into ISAs or pensions only after checking the tax cost of doing so. A bed-and-ISA transfer, for example, can be sensible for taxable holdings, but it is not automatically free of CGT.
Retain what still earns its place. A diversified core holding does not need to be sold merely because it was inherited. The question is whether it fits the policy, not whether it carries sentimental weight.
Leave room for family history
Inherited capital often carries memory as well as risk. A holding in a former family employer, a fund bought by a parent, or a share certificate kept for decades can be difficult to sell. It is reasonable to acknowledge that. A small, explicitly sized sentimental sleeve can be acceptable if it does not undermine the wider plan; what is less helpful is allowing an emotional attachment to set the portfolio's concentration without anyone naming it.
The measured approach is to separate the decision about the plan from the decision about the objects. The plan comes first. The objects can then be kept, reduced or released within limits that have been chosen deliberately.
Know when to bring in help
Complex estates — those involving trusts, foreign assets, unquoted shares, business relief or multiple pension schemes — usually warrant professional support. A solicitor or executor handles the legal administration; a tax adviser can model the CGT and income tax consequences; a regulated financial adviser can help with the investment policy and replanting sequence. Fee transparency matters, and so does keeping the number of advisers proportionate to the complexity of the estate.
For most UK investors, the lesson is unhurried. An inherited portfolio does not need to be redeemed on day one, nor preserved exactly as it was found. It needs a process: stabilise the administration, establish the tax position, audit the holdings, write the policy, and then replant in stages. The garden can wait a season. The plan should not wait forever.
