Selling a property in Essex can trigger a significant Capital Gains Tax (CGT) bill if you do not plan carefully. Whether you are selling a buy-to-let in Colchester, disposing of a inherited family home in Chelmsford, or flipping a renovation project in Southend-on-Sea, understanding CGT rules can save you thousands of pounds. At Rocket Accountants, we help property owners across Essex navigate CGT compliance and claim every available relief.
What Is Capital Gains Tax on Property?
Capital Gains Tax is the tax you pay on the profit when you sell or dispose of an asset that has increased in value. For property, the gain is calculated as the difference between the sale price (or market value) and the original purchase price, minus allowable costs.
The CGT rates on property are higher than for other assets. For the 2025/26 tax year:
Basic rate taxpayers
18%
On gains that fall within your basic rate income tax band
Higher & additional rate taxpayers
24%
On gains above the basic rate band — reduced from 28% in 2024
Everyone has an annual Capital Gains Tax allowance (also called the Annual Exempt Amount). For 2025/26 this is £3,000. If your total gains are below this, you pay no CGT. Married couples and civil partners can combine allowances, effectively doubling the exempt amount.
The 60-Day Reporting Rule: Do Not Miss It
Since April 2020, UK residents must report and pay CGT on residential property sales within 60 days of completion. This is a significant change from the previous system where you had until the January after the tax year ended.
The 60-day rule applies to:
- Sale of buy-to-let properties and second homes
- Sale of inherited property that is not your main residence
- Gifts of property (except to spouse or civil partner)
- Disposal of property held in a trust or by a company
You report the gain through HMRC\'s Capital Gains Tax on UK Property online service. Late reporting triggers penalties starting at £100, plus daily penalties for continued delay. At Rocket Accountants, we handle the entire 60-day reporting process for Essex clients, ensuring you never miss a deadline.
Private Residence Relief: The Main Home Exemption
If the property you are selling has been your only or main residence for the entire period you owned it, you typically pay no CGT at all. This is called Private Residence Relief (PRR). However, the rules become complex if:
- You let out part of your home or the entire property for a period
- You used part of the property exclusively for business purposes
- The garden or grounds exceed half a hectare (approximately 1.2 acres)
- You were not resident in the UK for tax purposes during ownership
- You lived abroad for part of the ownership period
Even if you do not qualify for full PRR, you may get partial relief. The final 9 months of ownership always qualify for relief, even if you were not living there. We calculate the exact relief available for every Essex property sale.
Letting Relief: What Changed in 2020?
Before April 2020, Letting Relief could reduce your CGT bill by up to £40,000 if you let out a property that was previously your main home. This relief has been significantly restricted and now only applies if you share occupancy with your tenant — effectively eliminating it for most landlords.
If you are an Essex landlord who previously relied on Letting Relief, you need to review your tax strategy. Our CGT specialists can help you explore alternative reliefs such as Business Asset Disposal Relief or transferring the property to a spouse to maximise allowances.
Allowable Costs That Reduce Your CGT Bill
You can deduct certain costs from your gain before calculating CGT. These include:
- Estate agent and solicitor fees for the sale and original purchase
- Stamp Duty Land Tax paid when you bought the property
- Costs of improvement works that add value — such as extensions, new kitchens, or loft conversions
- Costs of defending title or establishing your right to the property
Important: Routine repairs and maintenance do not count as improvement costs. You cannot deduct mortgage interest, council tax, or general upkeep. Keeping detailed records of improvement works is essential — we recommend photographing before and after and retaining all invoices.
CGT Strategies for Essex Property Owners
Transfer to a spouse
Transfers between spouses and civil partners are tax-free for CGT purposes. If one partner is a basic rate taxpayer and the other is higher rate, transferring the property before sale can reduce the overall CGT rate from 24% to 18% on some or all of the gain.
Use your annual exempt amount
If you have other assets with gains, consider selling them in a different tax year to spread your allowance. Or if you have unused allowance from previous years — unfortunately, CGT allowances cannot be carried forward.
Offset losses
Capital losses from other assets can be carried forward indefinitely and offset against future gains. We review your full portfolio to ensure no losses go unused.
Consider incorporation
For portfolio landlords with multiple properties, transferring to a limited company can offer tax advantages — including lower corporation tax rates and the ability to deduct mortgage interest in full. However, SDLT and CGT may apply on transfer, so professional advice is essential.
Business Asset Disposal Relief
If your property was used in a furnished holiday letting business or trading activity, you may qualify for Business Asset Disposal Relief (formerly Entrepreneurs Relief), reducing the CGT rate to just 10% on gains up to £1 million over your lifetime.
Inheritance Tax and Property: Planning Ahead
Property often forms the largest part of an estate, and inheritance tax (IHT) at 40% can force families to sell the family home. If you own property in Essex, consider these planning strategies:
- Gifting property during your lifetime — survives 7 years and the gift falls outside your estate for IHT
- Using the residence nil-rate band — an additional £175,000 allowance when passing your main home to direct descendants
- Equalising ownership between spouses to make full use of both nil-rate bands (£325,000 each plus residence nil-rate band)
- Considering a discretionary trust for property ownership, particularly for unmarried couples or complex family situations

Frequently Asked Questions
Do I pay CGT if I sell my main home?
Usually not — Private Residence Relief typically exempts your main home entirely. However, partial relief may apply if you let it out, used it for business, or have a large garden. We can calculate the exact relief for your situation.
What is the 60-day CGT reporting deadline?
You must report and pay an estimate of CGT within 60 days of completing a residential property sale. This is separate from your annual Self Assessment return. We handle this reporting for all our Essex property clients.
Can I deduct mortgage interest from my capital gain?
No — mortgage interest is not an allowable cost for CGT purposes. However, if you operate the property as a furnished holiday letting or through a limited company, mortgage interest may be deductible against income tax or corporation tax instead.
How much is CGT on a second home in Essex?
It depends on your income tax band. Basic rate taxpayers pay 18% on property gains, while higher and additional rate taxpayers pay 24%. After deducting your £3,000 annual exempt amount and any allowable costs, the net gain is taxed at these rates.
