Selling two or more properties that complete on the same day is not unusual — particularly for landlords selling a portfolio, beneficiaries winding up an estate, or partners dissolving a joint property holding. Each property is a separate CGT calculation, but you do not have to file a separate 60-day return for each one.
You can report several disposals on one return
HMRC's "Report and pay Capital Gains Tax on UK property" service lets you report more than one disposal on a single return. Within your CGT-on-UK-property account you add each property to the same return — so two or three completions on the same day go on one 60-day return, not several separate ones.
The 60-day deadline still runs from completion. If the properties complete on 1 October, the return covering all of them is due by 30 November, with any tax paid by the same date.
If a further disposal completes later in the same tax year, you do not start from scratch — you add it through your CGT-on-UK-property account, which tracks your year-to-date position.
Each gain is computed individually, then combined
On the return, the gain for each property is worked out separately:
- Proceeds of that property, minus
- Base cost of that property, minus
- Reliefs applicable to that property (PRR, lettings relief if applicable)
The individual gains are then brought together on the return, the annual exempt amount (£3,000) is applied once, and the tax due on the combined position is calculated.
The annual exempt amount applies once
The £3,000 annual exempt amount is per person per tax year — not per property and not per return. If you sell two properties in the same year, you cannot claim £3,000 against each.
If one property produces a gain and another a loss, the loss is set against the gain before the annual exempt amount is applied. Reporting the disposals on one return makes this netting straightforward.
Paying the tax
With the disposals on a single return, there is one payment for the combined tax due, by the 60-day deadline.
Joint ownership with different co-owners
If the properties are owned by different combinations of people — for example, property A is owned 50/50 by you and your spouse, and property B is in your sole name — each person reports their own disposals. You report your share of A and the whole of B on your return; your spouse reports their share of A on theirs. Each person's annual exempt amount applies to their own gains for the year.
Estate and executor scenarios
If you are an executor selling multiple inherited properties, the same approach applies — the disposals are reported on the estate's return (where you are acting as personal representative) or on your own return (where you inherited the property and are now selling it personally). Personal representatives have the full £3,000 annual exempt amount in the tax year of death and the two following tax years; after that the estate has no annual exempt amount and full CGT applies.
The year-end Self-Assessment
The 60-day report is provisional. On the year-end Self-Assessment return, all disposals of UK residential property in the tax year are brought together, the annual exempt amount is applied once across all gains, and any overpayment or underpayment made through the 60-day return is reconciled.
Practical steps
When multiple completions happen close together:
- Collect the completion statement for each property as soon as it is available
- Note the completion date(s) — day zero for the 60-day clock
- Calculate the gain on each property separately
- Report the disposals together on one CGT-on-UK-property return, applying the annual exempt amount once
- Pay the tax due by the 60-day deadline
Coordinating multiple disposals under time pressure is one of the most common reasons for using an agent. LetsFile can manage multiple disposals from the same portfolio sale — reported by a Chartered Accountant/Chartered Tax Advisor within 24 hours of receiving all your documents.
