ATED relief claims: why a company with a let property can still owe a return

ATED relief does not switch off the filing duty. If your company owns a UK home worth more than £500,000 and lets it commercially to an unconnected tenant, property rental business relief can cut the charge to nil, but you still have to claim it with a relief declaration return. That return is normally due by 30 April each year, and late filing penalties can apply even though you owe no tax.

The mistake is usually an assumption, not a tax bill. A company lets a flat at a proper rent, nothing is payable, and so nothing gets filed. This guide explains who falls within ATED, when the rental relief applies, what HMRC looks for and what a missed return can cost.

What is ATED and who has to pay it?

ATED (Annual Tax on Enveloped Dwellings) is a yearly charge on companies, partnerships with a company member and collective investment schemes that own UK residential property valued at more than £500,000. For 2026/27 the charge runs from £4,600 to £303,450, depending on the property’s value. Reliefs can reduce or remove it, but you have to claim them.

HMRC describes ATED as an annual tax payable mainly by companies that own UK residential property valued above £500,000. Individuals who own property in their own names are not caught. A “dwelling” covers any building used or capable of being used as a home, including gardens and grounds. Hotels, care homes and student halls of residence are not dwellings, although an ordinary student house is.

The band comes from your property’s value at 1 April 2022, or its value on the date you bought it if that was later. The next revaluation date is 1 April 2027, and a property above £500,000 at that point could come into scope from 1 April 2028. If you own something near a band boundary, it is worth getting a valuation ahead of time. The charges are also uprated every year, and the 2026/27 increase was 3.8%.

Does a company with a let property still need to file an ATED return?

Yes. Reliefs are not applied automatically, so you still have to claim them. Where a relief reduces the charge to nil, you submit a relief declaration return through HMRC’s ATED online service. One return can cover several properties if they all qualify for the same relief, but you need a fresh return every year.

HMRC’s position is that reliefs have to be claimed in the annual return or in a relief declaration return. On the GOV.UK page for ATED reliefs and exemptions, the relief declaration return is the route when a claim takes the charge to nil. You do not need to enter property details or a valuation on it. It is a short return, but it is still a return.

If you are not sure whether your company needs to register for the online service or file at all, our ATED return accountant team can check the position for you.

When does property rental business relief apply?

The relief applies when the company lets the property on a commercial basis to a third party, and nobody connected with the owner occupies it or has it available to occupy at any time. It sits alongside other reliefs, such as those for developers and traders, but it is the one letting companies rely on most. The conditions are narrower than many people assume.

Here is what has to be true:

• The Property Is Let On A Commercial Basis
• The Tenant Is A Third Party Not Connected To The Owner
• Nobody Connected To The Owner Occupies It Or Has It Available To Occupy
• The Company Runs A Genuine Rental Business With A View To Profit
• Any Empty Periods Involve Genuine Efforts To Let

GOV.UK states the relief applies where the property is let commercially to a third party and is not at any time occupied or available for occupation by anyone connected with the owner. That connection test catches directors, shareholders and their families. Even if the rent is at a full market rate, a letting to a shareholder’s relative will not qualify.

Occupation is counted day by day. Relief days and non-relief days are counted separately, so one family stay can turn a nil year into an apportioned charge.

The type of company matters too. Relief is not available where the property sits in a company that is not a qualifying rental business, such as a trading company, even if the property is let commercially. If you own a flat inside an operating company and let it on the side, check this before you assume anything.

Empty periods are less of a worry than people think. A company can still claim relief while it is actively trying to let a property, even if market conditions delay a tenant. Keep your evidence of that effort.

Three ways the same flat can end up

Take a company that owns a £650,000 flat in the £500,001 to £1 million band. The table shows how the filing changes depending on how the property is used.

The £1,160 figure is the £4,600 charge apportioned for 92 days out of 365. The real calculation depends on the exact dates, so treat it as an illustration. This is where we would expect most mistakes to happen in practice, because a quiet family stay is easy to forget when the return is prepared months later.

Why HMRC is checking rental relief claims

HMRC has been contacting companies that own UK residential property worth more than £500,000, have not declared profits for 2017 to 2020, and either claimed rental relief or never filed ATED returns. In HMRC’s view, a company with no profit is unlikely to qualify for the relief, so it may have a charge to pay. ICAEW covers the campaign in its report on HMRC contacting companies owning residential property.

The practical lesson is that the relief rests on a real rental business, and your company’s accounts and tax return should show it. Rental income should appear in your annual statutory accounts and in your company tax returns. If the accounts show nothing and the ATED return claims relief, those 2 documents will not agree.

Keep these on file for each property:

• Tenancy Agreements With Unconnected Tenants
• Rent Receipts And Bank Statements
• Letting Agent Appointment Letters
• Marketing Records For Any Empty Periods
• A Log Of Who Has Occupied The Property And When

If you suspect earlier years were missed, speak to an adviser before you file anything. HMRC’s letters invite a disclosure where relief was claimed incorrectly, and a prompt, accurate approach is usually better than waiting to be asked.

What happens if you miss the return?

HMRC charges a £100 penalty straight away for a late ATED return, with daily penalties and further penalties at 6 and 12 months. A return 12 months late can reach £1,600 in fixed penalties, before any extra penalties for deliberate failures. These apply to relief declaration returns as well, even when your charge is nil.

A relief declaration return is penalised in the same way as a return with tax to pay. Burges Salmon puts the total for a return 12 months late at £1,600. HMRC also charges interest and penalties for late payment or inaccurate returns, as noted on the GOV.UK ATED guidance. meritaccountantsburges-salmon

ATED deadlines to diarise

For a property within ATED on 1 April, both the return and any payment are due by 30 April. For 2026/27 that deadline was 30 April 2026, so the next one is 30 April 2027 for the 2027/28 period.

HMRC added the 2026/27 charges to its guidance on 2 December 2025, so it is reasonable to expect the 2027/28 amounts around the same time this year.

If your portfolio is bigger than a flat or two, good bookkeeping helps. Bookkeeping that tags rent by property makes the evidence trail much easier, and Xero bookkeeping can track rent and costs per property for you.

FAQs

Do I need to file an ATED return if my property is rented out?

Yes, if the property is a dwelling worth more than £500,000 owned by a company. If you qualify for rental relief, you file a relief declaration return instead of paying a charge, but you still have to file.

What is the ATED threshold for 2026/27?

The threshold is £500,000, and the 2026/27 charges start at £4,600 for properties worth more than £500,000 up to £1 million.

Does ATED apply to individuals who own property?

Not usually. It applies to companies, partnerships with a company member and collective investment schemes, not to individuals holding property in their own names.

Can a director live in a company-owned property and still claim relief?

Not for rental relief. Occupation by anyone connected with the owner removes the relief for those days, and the charge is apportioned by day.

Can I claim relief if the property is empty between tenants?

You can if you are genuinely trying to let it. Keep evidence such as an agent’s appointment letter and marketing records.
