How to Reduce Your Stamp Duty Bill: Legal Ways to Save

Nobody enjoys paying stamp duty. On a £500,000 property you're looking at £12,500, and it only goes up from there. You can't dodge it completely (not legally, anyway), but there are genuine ways to reduce what you owe. Some of these are well-known, others fly under the radar. Here's what actually works in 2026.

1. Claim First-Time Buyer Relief

The most obvious one. If you've never owned residential property before (anywhere in the world), you could save up to £8,750. The zero-rate threshold jumps from £250,000 to £425,000 on properties up to £625,000. That's a huge chunk of money.

Neither you nor anyone buying with you can have previously owned property, and it needs to be your main home. Your solicitor handles the claim through the SDLT return. We've got a full guide to first-time buyer relief if you want the detail.

2. Negotiate a Separate Price for Fixtures and Fittings

This is the one most people don't think about. Stamp duty is charged on the property, not on moveable stuff like furniture, carpets, curtains, white goods, and freestanding wardrobes. If you agree a separate price for these items with the seller, that amount gets excluded from the stamp duty calculation. Completely legal.

Say you're buying for £300,000 and the seller agrees £5,000 of that is fixtures and fittings. Your stamp duty is calculated on £295,000 instead. Saves you £250 in this case. Not life-changing, but on pricier properties with lots of included furnishings, it can really add up.

3. Negotiate the Purchase Price Below a Threshold

I talked about this in the first-time buyer article, but it bears repeating. That £625,000 threshold for first-time buyer relief is brutal. At £625,000, you pay £10,000. At £626,000, you pay £18,750. Nearly nine grand difference. If you're anywhere near that number, negotiate like your savings depend on it. Because they do.

For standard buyers the bands are less dramatic, but every pound you knock off the price still means less money in higher rate bands. It all counts.

4. Use Transfer of Equity Instead of a Sale

Buying from a family member? A transfer of equity might save you a packet. Instead of a standard sale at market value, the property gets transferred to you -- and stamp duty is only charged on any "consideration" you provide. That includes any mortgage you take on, but not the full market value.

So if your parents own a £400,000 house with no mortgage and gift it to you, there's no stamp duty at all. Zero. If there's a £100,000 mortgage that you take over, stamp duty is calculated on £100,000 rather than £400,000. Massive difference.

Fair warning: the person transferring the property might face capital gains tax or inheritance tax issues, so don't do this without proper tax advice from an accountant.

5. Consider Multiple Dwellings Relief

This one's a bit niche but can save serious money. If the property you're buying contains more than one dwelling -- think a house with a self-contained granny annexe -- you might qualify for MDR. It calculates stamp duty on the average price per dwelling instead of the total.

A £600,000 property with two dwellings? MDR assesses it as two £300,000 units. The stamp duty on that can be significantly less than paying on the full £600,000 as a single purchase.

The catch: the extra unit needs to be genuinely self-contained. Its own entrance, kitchen, and bathroom. A spare bedroom with a kettle doesn't cut it. Get a surveyor to confirm it qualifies before you count on this one.

6. Build Rather Than Buy

Here's one for the ambitious. Stamp duty only applies to what you buy, not what you build. Buy a plot of land for £150,000, spend £250,000 building your dream home, and you've got a £400,000 house where the stamp duty was calculated on the land alone. That's zero stamp duty for a standard buyer (it's within the £250,000 zero band). Buying the same house already built would cost you £7,500.

Self-build obviously comes with its own headaches -- planning permission, builder costs, the fact that everything takes twice as long as you expect. But purely from a stamp duty angle? It's a winner.

7. Reclaim the Additional Property Surcharge

Bought your new place before selling the old one? You'll have paid the 3% surcharge upfront, but sell the old property within 36 months and you can claim it all back. On a £300,000 purchase, that's £9,000 coming back to you. Don't leave it sitting with HMRC.

You claim it by amending your original SDLT return, either online or through your solicitor. The deadline is 12 months from selling your old home or 12 months from the SDLT filing date for the new purchase, whichever is later.

8. Explore Shared Ownership

Shared ownership lets you buy a share (usually 25% to 75%) and pay rent on the rest. The stamp duty advantage? You can choose to pay duty only on the share you're buying. A first-time buyer getting 50% of a £300,000 property would be assessed on £150,000 -- well within the zero-rate threshold. No stamp duty at all.

You can also pay on the full market value upfront, which avoids future stamp duty when you staircase. Ask your solicitor which makes sense for your situation.

9. Timing Your Purchase

You can't predict what the government will do, but paying attention helps. Stamp duty holidays have happened before (remember the Covid one?) and rate changes get announced in budgets. If there's a change coming, the timing of your completion could save or cost you thousands.

If you're selling one property and buying another, coordinating the completion dates so you sell first (or on the same day) avoids the 3% surcharge entirely. Your solicitor and estate agent should be all over this, but don't be afraid to push them on it.
