Selling your home is one of those life moments that feels like a fresh start—new chapter, new possibilities. But then the question creeps in: Will I have to pay taxes on this? It’s a valid worry. Nobody wants a surprise tax bill eating into their profits. The good news? Most people selling their primary home won’t owe a dime in taxes, thanks to some generous exemptions. But there are exceptions, and they can get tricky. Let’s dive into the ins and outs of taxes when selling your house, so you can plan ahead and maybe even save a bundle.
Navigating Taxes on Your Home Sale
When you sell your house, the tax that might come into play is capital gains tax (CGT). This is a tax on the profit you make—essentially, the difference between what you paid for the property and what you sell it for. Sounds simple, right? Well, not always. Whether you owe CGT depends on a few factors, like whether it’s your main home, if you’ve rented it out, or if it’s a second property. Let’s break it down step by step to make sense of it all.
Do You Pay CGT on Your Main Home?
If the house you’re selling is your primary residence, you’re likely in the clear. The UK offers something called private residence relief, which is a lifesaver for most homeowners. As long as the property has been your main home for the entire time you’ve owned it, you won’t owe CGT, no matter how much profit you make. Pretty sweet deal, right?
Private residence relief is one of the most generous tax breaks out there. It’s designed to protect homeowners from getting slapped with a tax bill just for selling their home.

But there are some conditions to qualify for this relief. Here’s what you need to check:
- The property is your only or main home for the entire ownership period.
- You haven’t rented out part of it (though having a lodger who shares your living space is fine).
- No part of the home was used exclusively for business (a home office is okay if it’s not permanent).
- The grounds, including any outbuildings, are under 5,000 square meters (about an acre).
- You didn’t buy the property just to flip it for a quick profit.
If you tick all these boxes, you’re golden. But life isn’t always that tidy. Maybe you moved out for a while or rented part of the house. That’s where things get murkier.
What If You Rented Out Your Home?
Let’s say you lived in your home for a few years, then rented it out to tenants. Does that mean you’re on the hook for CGT? Possibly, but not necessarily. You’ll still get some private residence relief for the time you lived there, plus an extra nine months at the end of your ownership, even if you weren’t living there. This “final period relief” is a nice little bonus from the tax folks.
Here’s an example to make it clear. Imagine you owned a house for 10 years, lived in it for 5 years, and rented it out for 5. You sell it and make a profit of £100,000. Private residence relief covers the 5 years you lived there, plus the last 9 months (0.75 years). That’s 5.75 years out of 10, or 57.5% of the ownership period. So, 57.5% of your £100,000 gain (£57,500) is tax-free. The remaining £42,500 is taxable, but you can subtract the annual CGT exemption (£3,000 in 2025/26), leaving £39,500 subject to tax.
The tax rate depends on your income. Basic-rate taxpayers pay 18%, while higher-rate taxpayers pay 24%. In this case, if you’re a higher-rate taxpayer, you’d owe 24% of £39,500, which is £9,480. Not pocket change, but not the end of the world either.
Can Letting Relief Save You?
If you shared your home with tenants while living there, you might qualify for letting relief. This is another tax break that can reduce or even eliminate your CGT bill. Letting relief applies if you rented out part of your home (like a spare bedroom) while still living there. It’s capped at the lower of three amounts:
- The amount of private residence relief you received.
- £40,000.
- The gain you made from the rented portion of the property.
Let’s say you rented out 10% of your home (a small room) and made a £50,000 gain when you sold. You get private residence relief on 90% of the gain (£45,000), leaving £5,000 taxable. Since the £5,000 gain comes from the rented portion, you could claim letting relief for that amount, wiping out the tax entirely. It’s like a get-out-of-jail-free card for small-scale landlords!
Selling a Second Home? Brace Yourself
Things get pricier if you’re selling a second property, like a holiday home or a buy-to-let investment. These don’t qualify for private residence relief, so you’re likely facing CGT on the full profit. With the annual CGT exemption stuck at a measly £3,000 in 2025/26, you won’t have much wiggle room to reduce your bill.
For example, if you sell a second home and make a £200,000 profit, you subtract the £3,000 exemption, leaving £197,000 taxable. At 24% (for higher-rate taxpayers), that’s a whopping £47,280 in taxes. Ouch. And here’s a kicker: you have to report and pay CGT on property sales within 60 days of completion. Miss that deadline, and you could face penalties.
Second homes are a tax minefield. Sellers need to plan ahead to avoid a nasty surprise when the tax bill lands.

One way to soften the blow is to deduct allowable expenses, like estate agent fees, solicitor costs, or major improvements (think adding a conservatory, not just repainting). These can reduce your taxable gain, so keep those receipts handy.
Inherited Properties: A Special Case
Inheriting a property can feel like a windfall, but selling it often comes with a tax sting. If you already own a home, the inherited property counts as a second home, so no private residence relief applies. The silver lining? CGT is only calculated on the increase in value from the date of inheritance, not the original purchase price.
Say you inherit a house valued at £300,000 and sell it a year later for £350,000. Your gain is £50,000. After the £3,000 exemption, you’re taxed on £47,000—£8,460 at 18% (basic rate) or £11,280 at 24% (higher rate). If the property’s value skyrocketed over decades, the tax bill could be much larger, especially in hot markets.
How to Minimize Your CGT Bill
Nobody wants to hand over a chunk of their profit to the taxman, so here are some strategies to keep your CGT bill in check:
- Deduct allowable costs: Include estate agent fees, legal costs, and improvement expenses to lower your taxable gain.
- Use your annual exemption: The £3,000 CGT allowance can take a small bite out of your bill.
- Time your sale: If you’re close to the tax year end, selling in the next tax year could let you use another £3,000 exemption.
- Offset losses: If you’ve lost money on other investments (like stocks), you can use those losses to reduce your taxable gain.
- Consider joint ownership: If you own the property with a spouse or partner, you can both use your £3,000 exemptions, doubling the tax-free amount.
I’ve always found that a little planning goes a long way. For instance, keeping detailed records of home improvements can save you thousands when it’s time to sell. It’s one of those “boring but worth it” tasks.
How Much Will You Actually Pay?
Calculating your CGT can feel like solving a puzzle, but it’s manageable if you break it down. Start with your sale price, subtract the purchase price and allowable costs, then apply any reliefs or exemptions. The government’s online CGT calculator for property sales is a handy tool to crunch the numbers, but it only works for property—not other assets like shares.
| Scenario | Taxable Gain | CGT Rate | Tax Owed |
| Main Home (Full Relief) | £0 | N/A | £0 |
| Rented Home (Partial Relief) | £39,500 | 24% | £9,480 |
| Second Home | £197,000 | 24% | £47,280 |
This table shows how different scenarios affect your tax bill. The key is knowing which reliefs apply and how to use them.
Final Thoughts: Plan Ahead
Selling your home is a big deal, and taxes shouldn’t catch you off guard. Most homeowners won’t face CGT thanks to private residence relief, but if you’ve rented out your home, own a second property, or inherited one, you’ll need to do some homework. My advice? Don’t wait until the sale is done to think about taxes. Talk to a financial advisor, keep track of expenses, and explore reliefs like letting relief or the annual exemption. A little foresight can save you a lot of stress—and money.
Have you sold a home and dealt with CGT? Or are you planning a sale and wondering about the tax implications? Either way, understanding the rules is the first step to keeping more of your hard-earned profit.
