Gifted Deposits and Stamp Duty: What You Need to Know
A gifted deposit from parents or family does not change your stamp duty bill. But if a parent is added to the property deed, the 5% additional dwelling surcharge can apply — a costly mistake that is easily avoided.
Key Takeaways
- •A cash gift to fund your deposit does NOT change your SDLT liability (confirmed by GOV.UK)
- •A parent added to the title deed who already owns property triggers the 5% surcharge — potentially £20,000+ on a £400,000 home
- •All lenders require a formal gift letter; most require source-of-funds verification under AML rules
- •A gift that is repayable is a loan — lenders and HMRC treat it differently
- •Gifts over £3,000 per year may be subject to IHT if the donor dies within 7 years

Does a Gifted Deposit Affect Stamp Duty?
No. SDLT is calculated on the purchase price of the property, not on the source of your funds. Whether your deposit comes from your own savings, a gifted lump sum from parents, an inheritance, or a combination of all three, the stamp duty calculation is identical. HMRC does not ask where the money came from when calculating your SDLT liability.
This is confirmed by HMRC guidance on SDLT: the chargeable consideration is the price paid for the property, not the funding arrangements the buyer uses to meet that price. A £350,000 purchase carries a standard SDLT bill of £7,500 regardless of whether the buyer contributes £10,000 from savings and £25,000 from a gift, or has saved the full deposit independently.
One special exception: If a mortgage is assumed as part of the transaction (i.e. a gifter also transfers a property with an outstanding mortgage), SDLT may be calculated on the outstanding debt as well as the cash consideration. This does not apply to straightforward cash gifts toward a buyer's deposit.
The Deed Ownership Surcharge Trap
The most expensive mistake buyers make when accepting family help is adding a parent to the property deed. This is sometimes suggested as a way to help with mortgage affordability — combining the parent's income to access a larger loan. But it carries a severe SDLT consequence.
If a parent already owns their own home (as most parents do), adding them to the deed of the new purchase means the transaction is counted as an additional dwelling purchase. This triggers the 5% additional dwelling surcharge (from October 2024), applied to the full purchase price:
| Purchase Price | Standard SDLT (child only) | SDLT with Parent on Deed | Surcharge Cost |
|---|---|---|---|
| £250,000 | £2,500 | £15,000 | +£12,500 |
| £350,000 | £7,500 | £25,000 | +£17,500 |
| £400,000 | £10,000 | £30,000 | +£20,000 |
| £500,000 | £15,000 | £40,000 | +£25,000 |
Additional dwelling surcharge: 5% on full purchase price. Applied when any buyer on the deed already owns a residential property (with limited exemptions).
Critical: The surcharge is non-refundable in most cases
Unlike some SDLT scenarios, paying the higher rate because a parent is on the deed does not automatically entitle you to a refund later when the parent transfers their share back. Removing a co-owner is a separate disposal — it may trigger SDLT again and incur capital gains tax. Always speak to a solicitor before adding anyone to a property deed.
The alternative — where a parent guarantees the mortgage without appearing on the deed — avoids the surcharge entirely. Guarantor mortgages are available from some lenders and achieve the same affordability benefit without the SDLT cost. See the first-time buyer guide for alternatives.
What Lenders Require for Gifted Deposits
UK lenders are required under the Money Laundering Regulations 2017 (as amended) to verify the source of funds for all deposits, including gifted amounts. The following are standard requirements across most high street lenders:
Formal gift letter
A signed letter from the gifter confirming: the amount, that it is an unconditional gift with no expectation of repayment, and that the gifter will have no interest in the property. Most lenders have standard templates.
Source of funds verification
The gifter must provide evidence of where the money came from: bank statements (typically 3 months), pension lump sum documentation, evidence of property sale proceeds, or inheritance/probate paperwork. Cash gifts without a verifiable trail will be refused by most lenders.
ID verification for the gifter
Under anti-money laundering regulations, the solicitor handling the conveyance must verify the identity of anyone contributing funds. The gifter will typically need to provide passport or driving licence and a recent utility bill or bank statement as proof of address.
Timing of the gift
Most lenders require gifted funds to be in the buyer's bank account for at least 3 months before the mortgage application, or at minimum to be visible in the account at the time of the affordability assessment. Late gifts (transferred days before exchange) may delay underwriting.
Gift vs Loan: The Critical Distinction
The word "gift" has a precise legal meaning in this context. A true gift is given with no expectation of repayment and no strings attached. If the arrangement is actually a loan — even an informal one between family members with no interest charged — it must be declared as such to the lender.
| Feature | True Gift | Family Loan |
|---|---|---|
| Repayment expected? | No | Yes (even informally) |
| Must be disclosed to lender? | Yes (gift letter required) | Yes (as a commitment) |
| Impact on affordability? | None (not a debt) | Reduces borrowing capacity |
| SDLT impact? | None | None (if cash-only) |
| IHT risk? | Yes — PET rules apply | No (debt is not a gift) |
| Risk of fraud allegation? | Low (if properly documented) | High if misrepresented as gift |
Mortgage fraud warning: Signing a gift letter declaring money is a gift when it is actually a loan is mortgage fraud — even if the parties are family members and no interest is charged. Lenders and the FCA take this seriously. If discovered, the mortgage can be called in immediately and prosecution may follow.
Inheritance Tax Implications
Cash gifts from parents to children are not immediately subject to inheritance tax. However, HMRC operates a 7-year rule on significant gifts through the Potentially Exempt Transfer (PET) framework. Understanding this is important for families making larger gifts.
Annual exemption: £3,000
Each parent can give up to £3,000 per year completely free of IHT considerations, regardless of when they die. Two parents can therefore give £6,000 per year combined. Unused allowance from the previous year can be carried forward once, allowing up to £12,000 from two parents in a single year.
Larger gifts: PET rules
Gifts above the annual exemption are treated as Potentially Exempt Transfers. If the gifter dies within 7 years of making the gift, it becomes subject to IHT on a sliding taper scale:
First-time buyer status: unaffected
Receiving a gifted deposit does not affect your status as a first-time buyer for SDLT relief purposes. The relief depends on whether you have previously owned a residential property — not on the source of your funds. A child receiving a large gift from parents who own multiple properties is still a first-time buyer if they have never personally owned a home.
Can Parents Gift Money Specifically for Stamp Duty?
Yes — there is no restriction on gifting money specifically to cover a stamp duty bill rather than the deposit itself. From HMRC's perspective, a cash gift is a cash gift regardless of what it will be spent on. The gifter does not need to specify "this is for the SDLT" — and in fact, keeping the purpose informal may make lender gift letter requirements simpler.
This approach is increasingly common as stamp duty costs have risen since 2021. A standard buyer purchasing at £500,000 owes £15,000 in SDLT — a substantial amount that many first-time buyers struggle to accumulate alongside a 10% deposit (£50,000). Parents gifting money specifically to cover SDLT allows the buyer to put their entire savings toward the deposit, preserving LTV.
Example: Split gifting strategy
Whether the gift is labelled for SDLT or deposit purposes, the lender will require the same documentation (gift letter, source of funds, ID). The practical distinction matters for your own financial planning: knowing your deposit is separate from your SDLT fund prevents last-minute funding shortfalls on exchange day.
Frequently Asked Questions
Does a gifted deposit change my stamp duty liability?
No. SDLT is calculated on the purchase price, not on where your deposit came from. A £350,000 property carries the same stamp duty whether the deposit is from savings, a gift, or a combination. The only way a gift changes your SDLT is if the gifter is added to the title deed while already owning property — which triggers the 5% additional dwelling surcharge.
Do I need to declare a gifted deposit to HMRC?
No separate HMRC declaration is needed for the gift itself in the context of your SDLT return. Your solicitor submits the SDLT1 return on your behalf, reporting the purchase price and transaction details. The gift is not a taxable event for you as the recipient. However, your lender and solicitor will require documentation of the gift under anti-money laundering regulations, and the gifter should be aware of the potential IHT implications if they die within 7 years of making a large gift.
Can parents gift money specifically to cover stamp duty?
Yes — this is legally straightforward and increasingly common. There is no restriction on using gifted funds for SDLT rather than the deposit. The lender requires a gift letter regardless of the intended use. For IHT purposes, the gift is treated identically to a deposit gift: amounts within the £3,000 annual exemption are clear; amounts above may be PETs and subject to the 7-year rule. Always document the gift formally, even between close family members.
