A dad wants to give his daughter the flat he rents out before she starts university. A mom wants to hand her son shares in the family business. It feels like a simple gift between family. But tax rules do not always see it that way. Giving away something valuable, even to someone you love, can still count as a taxable event.
According to the House of Commons Library, Capital Gains Tax brought in £13.3 billion in the 2024/25 tax year, and most of that came from a small group of people making big gains. Knowing the rules before you hand something over can save your family from a costly surprise.
Some people think Capital Gains Tax only shows up when you sell something for cash. That is not true. If you give an asset away, or hand it over to someone else, HMRC still counts that as a disposal. It does not matter that no money changed hands.
HMRC looks at what the item was worth on the day you gave it away, and that becomes your selling price for tax purposes. This is the heart of transfer assets CGT planning. You need to check if the item has gone up in value since you first got it. If it has, that growth in value might be taxed the moment you give it away, not later.
This surprises a lot of families. A parent might have bought some shares years ago and now wants to give them to a child. They think there is nothing to tell HMRC about since no cash was involved.
But if those shares are worth more now than when they were bought, HMRC still wants to know about that extra value. According to gov.uk’s guide on Capital Gains Tax, giving something away as a gift counts as disposing of it, in the same way as selling it does.
If your family is thinking about handing down property, shares, or other valuable things, it helps to get proper advice early. ETC Tax’s private client tax team can walk you through what counts as a disposal in your situation. And if the gift involves a business, the corporate and business tax team can help you plan the transfer the right way.
For the 2025/26 tax year, every person gets a Capital Gains Tax free amount of £3,000. This is called the annual exempt amount. Any gain above that gets taxed. If your gain falls in your basic rate band, you pay 18%. If it falls in your higher rate band, you pay 24%. These rates cover most things people gift, including houses that are not your main home, shares, and even crypto. These numbers changed after the Autumn Budget in 2024, when the government made property and non-property assets share the same rate.
Here is something worth knowing:
The £3,000 free amount does not roll over. If you do not use it this year, it is gone. It cannot be saved for next year. Because of this, spreading out gifts across a few different tax years can help you use more of your free amount overall. This part of transfer assets CGT planning often gets missed because people are focused on the gift itself, not on when it happens.
Knowing your numbers ahead of time saves stress later. According to the government’s guide on Capital Gains Tax allowances, the free amount only covers gains above certain reliefs and losses, so working out the real gain matters a lot before you commit to giving anything away.
ETC Tax’s private client tax service can help you check your numbers, and our tax consultancy services team can help with more detailed planning around timing gifts across tax years.
If you are giving something to your husband, wife, or civil partner, the rules are much kinder. Transfers between spouses or civil partners who live together are treated as no gain and no loss.
That means there is no Capital Gains Tax to pay right when the gift happens. The person who receives it simply takes on the same starting value the giver had. Tax is only worked out later, when that person eventually sells it or gives it to someone else.
This rule can be a smart tool for families. A couple can move an asset to whichever partner has a lower income, or one who has not used their yearly free amount yet, before selling it or passing it down the family line.
But this only works while the couple is actually living together in that same tax year. If a couple has separated, they need to check carefully whether this rule still applies to them, since the special treatment can end.
The gov.uk guidance on gifts to a spouse or charity confirms that these special rules only cover spouses, civil partners, and charities, and that normal rules apply to everyone else. If you and your partner are thinking about moving assets between each other as part of a bigger plan, ETC Tax’s private client tax advisors can help make sure it is done the smart way. Our tax partner pro service is also useful if your own adviser wants a second opinion on a family transfer.
Sadly, the kind spousal rule does not apply to children, grandchildren, parents, siblings, or most other family members. These people are called connected persons in tax rules.
When you give something to a connected person, HMRC still treats it as if you sold it at full market value, even if you got nothing for it, or sold it for a token price. So if you sell a house to your son for a small amount, HMRC still uses the full worth of that house to work out your gain.
This is where transfer assets CGT planning gets trickier. You may need a proper valuation, and the tax bill can be big if the item has grown a lot in value over time. A few important things to remember:
According to HMRC’s manual on connected persons, the word relative only covers a brother, sister, ancestor, or direct descendant, and does not stretch to nephews, nieces, aunts, or uncles.
ETC Tax’s private client tax team and our tax disputes and investigations advisors can help if HMRC ever questions a family transfer.
Sometimes, a special rule called Hold-Over Relief can push the tax bill down the road instead of getting rid of it. This mostly applies to gifts of business assets, shares in companies that are not listed on the stock market, farmland, and certain gifts connected to Inheritance Tax.
Where it works, the person giving the gift does not pay Capital Gains Tax right away. Instead, the person receiving it takes on a lower starting value, and the postponed gain becomes taxable only when they eventually get rid of the asset themselves.
Here is an easy way to picture it. Say someone gives away a business asset worth £50,000 that originally cost them £17,000. The taxable gain is £33,000. If both people agree to claim Hold-Over Relief together, no tax is owed at the time of the gift.
Instead, the person receiving it now has a starting value of £17,000, and they will pay tax on the whole gain whenever they sell it themselves.
Both people involved need to make a joint claim using a special form, and this must happen within four years of the end of the tax year the gift was made in. This relief usually does not cover ordinary homes that are not used for business, which makes gifting a house one of the trickier parts of family tax planning. According to HMRC’s official helpsheet on relief for gifts, both the giver and receiver must agree to the claim in writing. ETC Tax’s private client tax and innovative tax reliefs teams can check if this relief fits your situation.
Let us walk through a simple example. Picture a landlord who bought a flat years ago for £150,000, and rents it out to tenants.
That flat is now worth £280,000, and she wants to give it to her son. Because her son counts as a connected person, HMRC treats this as if she sold the flat for the full £280,000, even though she is not getting a single pound for it.
The gain here is £130,000. After taking away her £3,000 yearly free amount, she is left with £127,000 that gets taxed, either at 18% or 24%, depending on how much she earns that year. Since this flat is not used for business, Hold-Over Relief does not apply here, so the tax becomes due even though no money actually came her way.
This shows why anyone thinking about giving property to a family member should get the real numbers checked first, before signing anything.
The government’s page on reporting and paying Capital Gains Tax on UK property explains that this kind of gain usually needs to be reported and paid within 60 days of the transfer. ETC Tax’s property tax service works with landlords and property owners on exactly this kind of family transfer, and our private client tax team can help with the wider planning around it.
Business owners often want to bring their children or other family members into the company by giving them shares, instead of selling them. This gets treated the same way as any other gift to a connected person, meaning it is deemed to happen at open market value.
Since private company shares do not usually have a clear price tag, a proper valuation is often needed. If that number looks too low, HMRC might open a closer look into it.
When the shares belong to an unlisted trading company, Hold-Over Relief is normally available. This can push the gain down the road until the next generation eventually sells those shares themselves.
Some business owners choose not to use this relief if their gain already qualifies for Business Asset Disposal Relief, which currently taxes qualifying gains at a lower 14% rate for 2025/26, rising to 18% starting April 2026, up to a £1 million lifetime limit. Sometimes paying the lower rate now works out cheaper than waiting, depending on your own situation.
According to gov.uk’s guidance on Business Asset Disposal Relief, this relief can reduce the Capital Gains Tax owed on qualifying business assets, but strict conditions must be met throughout a set qualifying period.
ETC Tax’s employee share schemes and buying or selling a company teams can help business owners plan the right way to hand shares down.
Crypto is treated the same way as shares or property when it comes to Capital Gains Tax. Giving crypto to a family member, other than a spouse or civil partner, counts as a disposal at market value on the day it happens.
A lot of crypto holders think that since no bank or exchange was involved, HMRC will not notice. That is not true. If the value of the crypto went up since you got it, the gain gets worked out the same way as any other gift to a connected person, and it still needs to be reported.
This catches people out more than you might think, since crypto often moves in and out of wallets quietly, with no obvious paper trail like a bank statement or a signed deed.
But HMRC still expects the same reporting, whether the asset is a house, a share, or a coin sitting in a digital wallet. Anyone planning to pass crypto down to children or grandchildren should treat it with the same care as any other valuable family gift.
HMRC’s cryptoassets guidance confirms that giving away cryptoassets counts as a disposal for tax purposes, in the same way selling them does. ETC Tax’s crypto tax specialists understand these rules closely, and our private client tax team can help make sure crypto transfers to family are reported correctly from the start.
Once you have worked out the gain from a gift, it usually needs to be reported to HMRC. For UK homes and property that are not your main residence, this must generally happen within 60 days of the transfer, using HMRC’s online property reporting service.
For most other things, like shares or crypto, the gain gets reported through the Capital Gains Tax part of a Self Assessment tax return, following the normal yearly deadline. Missing these deadlines can lead to extra charges and interest stacked on top of the tax itself.
This is why building reporting into your plan from day one matters so much. Waiting until the deadline approaches can lead to rushed valuations, missing paperwork, or forgotten forms. Getting organised early, especially with property or business assets, makes the whole process smoother for everyone in the family.
According to gov.uk’s guidance on reporting other capital gains, gains outside of UK residential property can be reported either through a Self Assessment tax return or through HMRC’s real-time service.
ETC Tax’s private client tax team and tax disputes and investigations specialists can help ensure your reporting stays on time and accurate, whatever the asset involved.
Do I have to pay Capital Gains Tax if I give my house to my son?
Yes, in most cases. Gifting property to a child is treated as a disposal at market value, and any gain above your annual exempt amount is taxable, unless the property qualifies for a specific relief such as Private Residence Relief.
Is gifting shares to a family member tax-free in the UK?
Not automatically. Shares given to anyone other than a spouse or civil partner are valued at market value for Capital Gains Tax purposes. Hold-Over Relief may defer the tax if the shares are in an unlisted trading company, but a claim must be made.
Can I gift an asset to my spouse to avoid Capital Gains Tax?
Transfers between spouses or civil partners who live together are treated as no gain, no loss, so no Capital Gains Tax is due at that point. Tax is only calculated when the receiving spouse later disposes of the asset.
What happens if I sell an asset to a family member for less than it is worth?
HMRC still uses the full market value to calculate any gain, not the price actually paid. Selling below market value to a connected person does not reduce your tax bill.
Giving something valuable to a family member can feel simple, but it can also come with a tax bill you did not see coming. This is common with property, business shares, and even crypto. The rules about who counts as family, when relief applies, and when to report to HMRC are not always easy to figure out on your own. Getting it wrong can cost real money.
That is where ETC Tax comes in. Our team helps families across the UK plan these transfers the smart way, whether it is property, crypto, or shares in a family business. Before you hand anything down, talk to ETC Tax’s private client tax advisors first, so your family keeps more of what you worked hard for.
