Selling a Former Main Residence: Capital Gains Tax Explained

Many homeowners assume that because a property was once their main residence, there will be no Capital Gains Tax to pay when it is sold.

Unfortunately, the position is not always that straightforward.

If you have moved out of a property, let it to tenants, inherited another home or owned multiple properties during the period of ownership, a Capital Gains Tax liability may arise when the property is eventually sold.

Understanding the available reliefs and reporting requirements before completion can help avoid unexpected tax bills and missed deadlines.

What is Private Residence Relief?

Private Residence Relief (PRR) is one of the most valuable tax reliefs available to homeowners.

Where a property has been occupied as your only or main residence throughout the entire period of ownership, any gain arising on disposal will often be fully exempt from Capital Gains Tax.

However, problems can arise where the property has not been your main residence for the entire period of ownership.

When Could Capital Gains Tax Become Payable?

A tax liability may arise where:

• The property was rented out after you moved elsewhere.

• You owned more than one property at the same time.

• The property became a second home.

• You inherited the property and did not occupy it as your residence.

• You moved out for a prolonged period before selling.

In these situations, only part of the gain may qualify for Private Residence Relief.

How is the Gain Calculated?

The gain is generally calculated by deducting:

• The original purchase price.

• Stamp Duty Land Tax.

• Legal fees on purchase.

• Capital improvement costs.

• Estate agent fees.

• Legal fees on sale.

• Any capital enhancements to a property

• "Staging costs" incurred specifically to help sell the property

from the sale proceeds.

Once the gain has been calculated, any available reliefs and annual exemptions can then be considered.

What About Letting the Property?

A common scenario involves a homeowner moving into a new property while retaining and letting their former residence.

Many people assume that because they once lived in the property, the entire gain will remain exempt.

In reality, the gain is normally apportioned between qualifying and non-qualifying periods of ownership.

The calculation can become particularly complex where there have been periods of occupation, letting, absence from the property or changes in ownership.

The Final Period Exemption

Even where a property is no longer occupied as a main residence, the final period of ownership may still qualify for Private Residence Relief.

This can provide valuable relief in many cases and reduce the taxable gain.

However, the interaction between the final period exemption and other reliefs can be complicated and should be reviewed carefully before any disposal.

Do I Need to Submit a 60-Day Capital Gains Tax Return?

If Capital Gains Tax is payable following the disposal of a UK residential property, a Capital Gains Tax on UK Property Return will often need to be submitted within 60 days of completion.

Many taxpayers remain unaware of this requirement and only discover the reporting obligation after the deadline has passed.

Late filing penalties and interest may apply where a return is submitted after the statutory deadline.
