The Estate Earns Interest — and HMRC Wants Tax on It

Yes. If money keeps arriving after someone dies — their savings still earning interest, their shares still paying dividends, a flat they owned still being let — that income is taxable, and the estate is the taxpayer. It has nothing to do with inheritance tax, and it is separate from the tax the person paid while they were alive. The longer probate takes, the more of this income builds up, and someone has to declare it and settle the bill before the beneficiaries receive their share cleanly.

That someone is the personal representative: the executor named in the will, or the administrator where there is no will. From the day after the death until the estate is wound up — a stretch HMRC calls the administration period — the estate stands as its own small taxpayer, and the personal representative reports its income to HMRC on the estate's behalf.

It catches families out because it is invisible at first. Nobody sends a tax demand in the opening weeks. Interest simply mounts up in a frozen account, or a tenant keeps paying rent into a managing agent's account, and the tax question only surfaces months later, when the estate is finally being shared out and a beneficiary is handed a form to copy onto their own tax return.

The short answer: for a while, the estate is its own taxpayer

Think of the money in three separate boxes, because HMRC does. The first is everything the person earned up to the day they died — their wages, pension and interest during their final tax year. That belongs on their own personal tax return, made up to the date of death, and it is the last return they will ever have. The second box is inheritance tax, a one-off charge on what the estate was worth at the moment of death; it is a tax on value, not on income, and it is settled quite separately.

The third box is the one people miss. From the day after the death, the assets carry on doing what assets do. Cash earns interest. Shares pay dividends. A let property collects rent. All of that is new income, arising after the person has gone, and it belongs to the estate rather than to the deceased or to any beneficiary who has not yet been paid. Tax on it is the personal representative's responsibility for as long as the administration lasts.

One feature surprises people, and it works in the estate's favour as often as against it: the estate has no personal allowance and pays only the basic rate, with dividends taxed at the dividend rate, no matter how large the estate is. There are no higher-rate bands at the estate level. The final reckoning happens later, at each beneficiary's own rate, once the income reaches them — which is exactly what the R185 is for.

Three tax bills, and why they get muddled

Families routinely conflate these, and it leads to real mistakes — most often paying inheritance tax and assuming the estate's tax affairs are therefore closed. They are not. Keeping the three apart is the single most useful thing you can do.

• The deceased's final personal return. Covers income up to the date of death. HMRC usually issues this after being told of the death, or you request it. It squares off the person's own tax.
• Inheritance tax on the estate. A charge on the value of everything owned at death, once allowances are applied. Whether it needs a full account at all depends on the estate — we cover when a full IHT400 is required rather than the shorter excepted-estate route separately, because that decision also drives how long the grant takes.
• Income tax during administration. The subject of this page: tax on income the estate earns after the death and before it is distributed.

They run on different timetables and to different tax offices' expectations, and a payment against one does nothing for the others. It is entirely normal for a small estate to owe no inheritance tax at all and still have an income tax job to do, purely because a savings account carried on paying interest for a year while probate ground on.

What actually counts as estate income

The taxable income is the ordinary stuff that assets throw off after the death:

• Interest from banks, building societies and NS&I, credited after the date of death.
• Dividends from shares and funds held in the estate.
• Rental income from any property that continues to be let while the estate is administered.
• Other income such as certain trust distributions or income from a business the estate is running on.

What does not count is just as important. The capital value of the assets themselves is not income — inheriting a £200,000 house is not £200,000 of income, though a gain when it is later sold is a separate capital gains matter for the estate. And money that never enters the estate generates no estate income at all. A life policy written in trust, or a lump sum paid at the scheme's discretion, is paid to the trustees or nominated people directly; it bypasses the estate, so it neither swells the inheritance tax figure nor produces administration-period income. Whether a particular payment lands inside or outside the estate is worth pinning down early — it is the same question that decides whether a death in service lump sum forms part of the estate for probate, and the answer changes both the tax and the timing.

How the estate pays it: the informal route and the formal one

There are two ways this is settled, and which one applies depends on how much income there is and how complicated it is.

For a straightforward estate with modest income, HMRC operates an informal arrangement. In simple cases you can report the income and pay the tax without registering the estate and filing a full trust and estate return, which spares a grieving family a heavy piece of paperwork. The conditions and any limits are set out on gov.uk and are revised from time to time, so check the current position rather than relying on what a relative remembers from a previous estate.

Where the estate is larger, runs for a long time, has substantial rental income, or is otherwise complex, HMRC will expect the estate registered and a formal return filed for each tax year of the administration. Either way the tax is paid from estate funds — which raises a practical snag, because in the early months the estate's cash may be frozen and inaccessible. Executors frequently end up covering costs personally and reclaiming later; if that is happening to you, our guide on recovering money you have fronted for the estate sets out how to keep the record straight so you are properly reimbursed.

The R185 your beneficiaries will need

When you pay income out to a beneficiary, they need to know what it was and what tax has already been dealt with, because that income has to go on their own tax return — the estate paid tax at the basic rate, but the beneficiary might be a non-taxpayer entitled to reclaim some of it, or a higher-rate taxpayer who owes more.

The document that carries this information is form R185 (Estate Income). The personal representative completes one for each beneficiary, showing the estate income allocated to them and the tax accounted for on it. The beneficiary then uses those figures on their own return. It is a small form, but leaving it out causes disproportionate trouble: a beneficiary who is never given an R185 either cannot complete their return properly or unwittingly gets their tax wrong. Issue it when you distribute income, keep a copy with the estate papers, and the beneficiary's side becomes simple.

What a long probate quietly does to the tax

This is the part that connects the tax to everything else that is dragging. The administration period does not end on a fixed date — it ends when the estate is wound up. The longer that takes, the longer the estate holds income-producing assets, and the more administration-period income there is to report. A probate that runs to eighteen months instead of six is not just eighteen months of worry; it is a longer stretch of the estate being a taxpayer, with more interest and, potentially, more rent to account for.

Several ordinary delays feed this. A property that cannot be sold until the grant arrives may sit let, or empty and costing money, for months — you can market a probate house and even accept an offer, but you cannot complete the sale before the grant, so the asset lingers in the estate longer than anyone wants. An estate that needs the full inheritance tax account joins a longer queue before the grant is even applied for. Each week of delay is another week the estate keeps earning, and keeps owing.

It is worth seeing the contrast with money that is arranged to sidestep all of this. Proceeds held in trust do not join the estate, do not wait for the grant, and do not add to the administration-period income the executor has to untangle — which is exactly why some families use life cover written in trust to provide funds outside the estate. If you are looking at a slow, cash-poor estate and thinking about how your own affairs would land on the people you leave behind, you can get life insurance quotes and ask an FCA-authorised broker how cover written in trust would behave, so the money reaches people without waiting on probate at all.

Scotland and Northern Ireland

Income tax on an estate is a UK-wide matter run by HMRC, so the substance described here — administration-period income, the basic-rate charge, the R185, the informal route — applies whether the estate is being dealt with in England, Wales, Scotland or Northern Ireland. The concept of an administration period does not stop at a border.

What differs is the grant that ends the wait, and therefore how long the estate keeps earning. In Scotland the equivalent of probate is confirmation, applied for through the sheriff court, and in Northern Ireland the grant is obtained through the probate office of the High Court. Neither changes the income tax rules, but both change the timetable, which — as above — is what really governs how much administration-period income piles up.

Frequently asked questions

Does an estate pay income tax on interest during probate?

Yes. Income arising after the death, such as bank interest, dividends and rent, belongs to the estate and is taxable during the administration period. It is separate from inheritance tax and from the deceased's own final return, and the personal representative is responsible for reporting it and paying the tax before the estate is distributed.

What is an R185 and who needs one?

Form R185 (Estate Income) is the statement a personal representative gives each beneficiary, showing the estate income paid to them and the tax already accounted for. Beneficiaries use it to complete their own tax returns, so it should be issued when income is distributed to them and a copy kept with the estate papers.

Can small amounts of estate income be dealt with informally?

HMRC operates informal arrangements for straightforward estates with limited income, which avoid a full trust and estate return. The conditions and limits are set out on gov.uk and change from time to time, so check the current position rather than relying on what applied to an earlier estate a relative dealt with.
