Do You Pay Stamp Duty When Selling a House in the UK? (Who Pays It, When It Applies & Common Confusions) 2026 Guide
The short answer is no, you don’t pay Stamp Duty when you sell a house in the UK. Stamp Duty Land Tax is a purchase tax paid by the buyer rather than a sale tax paid by the seller, and this is one of the most persistent misunderstandings in UK property because the term “stamp duty” tends to get used loosely in conversations about house sales by people who haven’t recently sold or bought.
The longer answer involves several edge cases, related taxes that do apply to sellers, and the specific timing rules around when SDLT actually becomes payable. The fuller picture is worth understanding because some of these misunderstandings affect real decisions, particularly if you’re trying to work out what your net proceeds will be from a sale.
Who Actually Pays Stamp Duty
Stamp Duty Land Tax in England and Northern Ireland is paid by the buyer of the property, not the seller, and the equivalent taxes in Scotland (Land and Buildings Transaction Tax, LBTT) and Wales (Land Transaction Tax, LTT) also fall on the buyer rather than on you as the seller.
The legal basis for this is straightforward enough: SDLT is a tax on the acquisition of property, calculated on the purchase price the buyer pays for it. Your role as the seller in the SDLT process is only indirect, since the buyer’s solicitor handles the calculation and payment as part of their conveyancing work. You receive the sale proceeds in full from the buyer’s solicitor, and the buyer’s solicitor then submits the SDLT return and pays the tax directly to HMRC from funds the buyer has provided for that purpose.
What You Actually Pay When You Sell
As a seller in the UK, you’ll pay various costs and taxes during a sale, but Stamp Duty isn’t one of them. The actual financial obligations you’ll face on the seller’s side typically include several things worth understanding properly.
Capital Gains Tax on Non-Main-Residence Properties
Capital Gains Tax can apply to your sale, and this is the one that catches sellers out most often because it’s a real cost and it can be substantial. CGT applies when a property other than your main residence is sold for more than you paid for it, with rates in 2026 sitting at 18% for the basic rate band and 24% for the higher rate band, applied to the gain rather than the full sale price.
CGT doesn’t apply to the sale of your main residence (where Private Residence Relief provides full exemption for most homeowners), but it does apply to second homes, holiday properties, rental properties, properties owned through buy-to-let arrangements, inherited properties that you’ve subsequently sold, and properties bought to renovate and sell quickly where HMRC may treat the activity as trading rather than investment.
The Other Costs You Actually Face
You’ll also pay estate agency fees of typically 1 to 3 percent of the sale price plus VAT for high street estate agents (online agents charge less, sometimes a flat fee), conveyancing fees of around £700 to £2,000 plus disbursements, mortgage exit fees if you have an outstanding mortgage being redeemed at completion (typically £50 to £300 plus any early repayment charges of 1 to 5% of the outstanding balance depending on the product), and removal costs which aren’t strictly a sale cost but are typically associated with the move.
The combined cost on your side as a seller typically totals 2 to 5 percent of the sale price, varying significantly by property value, your specific fee arrangements, and your mortgage situation. None of this is Stamp Duty, which is why the question gets confused so often.
The Confusions That Come Up Most Often
Several misunderstandings appear regularly when people talk about Stamp Duty and selling, and they’re worth clearing up because they affect real decisions.
Confusing the Onward Purchase with the Sale
The first is when someone says they’re “paying Stamp Duty on my onward purchase”. This is technically correct but it’s the buyer’s SDLT on the new property, not Stamp Duty on the sale of the old one. If you’re a homeowner selling one property and buying another, you’ll pay Stamp Duty on the property you’re buying but nothing on the property you’re selling, and the two transactions are taxed separately even though they typically happen on the same day.
The second comes up when someone says they “had to pay an extra 5% because I owned another property at completion”. This is the additional dwelling surcharge applied to buyers of second homes, holiday properties, or rental properties (currently 5% above standard rates), and again it’s paid by the buyer rather than the seller of the original property. If you’re selling your main residence and your buyer happens to be purchasing it as a second home, you don’t incur the surcharge yourself.
Mistaken Deductions and First-Time Buyer Misconceptions
The third confusion is when sellers think “Stamp Duty was deducted from my sale proceeds”, which shouldn’t happen. You should receive the full sale price minus only your own fees and any outstanding mortgage, because SDLT is collected from the buyer’s funds by the buyer’s solicitor. If something has been deducted from your sale proceeds in the name of Stamp Duty, that needs investigating because something has gone wrong.
People sometimes also think they “pay Stamp Duty if I move from a smaller house to a bigger house”, but the Stamp Duty is paid on the bigger house being purchased rather than on the smaller house being sold. The sale of your smaller house attracts no Stamp Duty at all. And first-time buyer relief applies only to the purchase side, not to any subsequent sale, so the relief works on the buying side only.
When SDLT Becomes Payable
For buyers (which you might be if you’re also buying an onward property), the timing of SDLT matters because there’s a strict deadline involved. SDLT must be paid and the SDLT1 return filed with HMRC within 14 days of completion in England and Northern Ireland, while Scotland’s LBTT and Wales’s LTT both have 30-day filing deadlines instead. The deadlines are administrative rather than the actual liability dates, which arise on completion itself.
Late filing triggers an automatic £100 penalty after the deadline, rising to £200 after three months and a percentage-of-tax penalty after six months, plus interest on any unpaid amount. For you as the seller though, the SDLT timing is irrelevant to your direct obligations because the buyer’s solicitor handles the SDLT return and payment from the buyer’s funds, so you don’t need to track the deadline yourself.
The Unusual Cases Where Sellers Might Be More Involved
A few unusual situations involve sellers more directly in SDLT considerations, though they don’t affect most standard sales.
If you and your buyer have other connected transactions between you, HMRC can treat them as “linked” for SDLT purposes and apply higher rates, which is uncommon but can arise in family transactions, partnerships, and certain commercial sales. Sales between connected parties (selling to a spouse, civil partner, or company in which you have an interest) can trigger different SDLT treatment than an arm’s length sale, and independent tax advice is worth obtaining if this applies to your situation.
For leasehold properties, complex lease arrangements involving assignments, underleases, or surrenders can trigger SDLT in unusual ways. The buyer of the lease pays the SDLT, but you might have reporting obligations in certain assignment situations. Sub-sales, where a property is sold and then immediately re-sold (typical of property development chains), follow specific SDLT rules to avoid double taxation, and the middle party in such arrangements may have specific filing obligations.
These scenarios are unusual for standard residential sales and don’t affect most sellers, but they’re worth knowing about if your situation looks more complex than a typical sale.
What If the Buyer Doesn’t Pay Their SDLT
You have no direct exposure if your buyer fails to pay their SDLT, because the liability rests with the buyer and HMRC enforcement targets the buyer rather than you. The only exception is in very specific scenarios where you’ve been party to an arrangement designed to avoid SDLT, which doesn’t arise in standard sales.
After completion has happened, your involvement in the SDLT process is essentially finished. The buyer’s solicitor handles the return and payment, and the Land Registry registers the title transfer once HMRC has confirmed receipt of the SDLT. If you’ve sold properly and the buyer mismanages their SDLT afterwards, that’s the buyer’s problem rather than yours.
How Cash Sales Work with Stamp Duty
When you sell your property to a top cash buying company like Sell House Fast, the same SDLT structure applies as with any other sale. The cash buyer pays the SDLT on their purchase, and you don’t pay any Stamp Duty on the sale yourself.
The difference with cash sales is usually that the cash buyer covers your legal fees as part of their offer, which reduces your net cost of the sale considerably. The cash buyer’s SDLT bill is unaffected by who pays the conveyancing fees, but for you as the seller, the practical implication is that the headline offer figure ends up closer to the actual amount you receive because the legal costs and other deductions that would normally come out of your sale proceeds get absorbed by the buyer instead.
The Bottom Line
You don’t pay Stamp Duty Land Tax when you sell a house in the UK. SDLT is a purchase tax paid by the buyer rather than a sale tax paid by you, and the misunderstanding comes from the way “stamp duty” gets referenced in conversation about house moves, where the same household is often both selling one property and buying another and the SDLT on the purchase gets associated with the sale that funded it.
What you do pay as a seller includes Capital Gains Tax (on second homes and rental properties), estate agency fees, conveyancing fees, mortgage exit charges, and various smaller costs. The cumulative seller-side costs are real and worth budgeting for, but Stamp Duty isn’t among them, and anyone who tells you otherwise has the basic structure wrong.
