Stamp Duty Land Tax Return Fees: HMRC, Solicitor, and Penalties

HMRC does not charge a fee to file a Stamp Duty Land Tax return. Stamp Duty Land Tax return fees, in the sense buyers usually mean them, come from the solicitor or conveyancer who prepares and submits the return on your behalf, and typically run £50 to £150. The tax itself is separate, calculated on the purchase price, and is often the far larger number on your completion statement.

What HMRC Charges to Process the Return

Nothing. HMRC’s Stamp Taxes Online service lets solicitors and conveyancers submit returns electronically at no cost, and paper returns are processed without a fee either.¹ The only money HMRC expects is the SDLT itself. If your transaction falls below the tax threshold or qualifies for full relief, you may owe no tax at all, and even then the filing costs nothing on HMRC’s side.

What Solicitors and Conveyancers Charge to File

The line on your completion statement labelled for the SDLT return is the solicitor’s charge, not a government fee. Professional fees for handling the submission typically fall between £50 and £150. A straightforward residential purchase sits at the lower end; transactions involving multiple buyers, reliefs, or mixed-use property sit higher.

That charge covers gathering the required data, completing the form, submitting it electronically, and obtaining the SDLT5 certificate that Land Registry needs before it will register your ownership. Some firms roll this work into a single fixed conveyancing fee alongside title searches and mortgage registration, so it may not appear as a standalone line item. If you want to know exactly what you are paying for the SDLT filing, ask your solicitor to break out their disbursements before you commit.

What the Tax Itself Costs

The tax bill dwarfs any professional filing fee. SDLT is calculated on a progressive basis, meaning each portion of the purchase price is taxed at its own rate. For standard residential purchases (not first homes or additional properties), the current bands are:²

Up to £125,000: 0%
£125,001 to £250,000: 2%
£250,001 to £925,000: 5%
£925,001 to £1.5 million: 10%
Above £1.5 million: 12%

On a £350,000 home, you pay nothing on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the remaining £100,000 (£5,000). Total SDLT: £7,500. Both the return and the tax payment are due within 14 days of completion.¹

First-Time Buyer Relief

If you have never owned property before, you qualify for a lower rate structure, provided the purchase price does not exceed £500,000. Under first-time buyer relief, you pay no SDLT on the first £300,000 and 5% on the portion between £300,001 and £500,000.² On a £400,000 first home, that works out to £5,000 in SDLT instead of £7,500 under the standard rates.

Every buyer on the transaction must be a first-time buyer. If you are purchasing with a partner who already owns property, the relief disappears entirely and you revert to standard rates.² Properties priced above £500,000 also lose the relief completely. You still need to file the return and claim the relief on the form; it is not applied automatically.

Surcharges for Second Homes and Non-Residents

Buying a second home or a buy-to-let property adds a 5% surcharge on top of the standard SDLT bands.² The first £125,000 is taxed at 5% rather than 0%, and every band above it rises by the same 5 percentage points. On a £350,000 buy-to-let, SDLT jumps from £7,500 under standard rates to £25,000. The surcharge applies whenever you will own more than one residential property after the purchase completes.

Non-UK residents face a separate 2% surcharge on top of whatever rates otherwise apply, including the additional property surcharge if relevant.³ A non-resident buying a second home pays 7 percentage points above the standard bands on each slice. These higher rates make it especially important that your return accurately reflects your residency status and property ownership, since errors in either direction can lead to a penalty or a refund you never claim.

When You Don’t Need to File a Return

Not every property transaction requires an SDLT return. The most common exemption is a freehold purchase where the total price is below £40,000. In that case, you owe no tax and no return.⁴ Other exempt transactions include:

Property left in a will, even if there is an outstanding mortgage on it.
Transfers on divorce or dissolution under an agreement or court order.
Gifts where no money, goods, services, or debt transfer is involved.
New or assigned leases of less than 7 years, where the price falls below the residential or non-residential threshold.

If your transaction does not fall into one of these categories, you need to file a return even when the tax bill is zero. A purchase at £130,000 that falls within the nil-rate band still requires a return. Skipping it triggers penalties and prevents Land Registry from registering your ownership.¹

Late Filing Penalties and Interest

The return and any tax owed must both reach HMRC within 14 days of the effective date, whether you file online or by post, and whether the tax bill is £500,000 or zero.¹ Miss it by even one day and an automatic £100 fixed penalty applies. If the return is still outstanding after three months, the penalty increases to £200.⁵

Returns that remain unfiled for more than 12 months trigger a tax-based penalty that can reach up to the full amount of SDLT due on the transaction.⁵ On a property where £10,000 in SDLT was owed, that is up to £10,000 in additional penalties on top of the original tax. These penalties stack, so a return filed 14 months late could incur the £100, the £200, and the tax-based penalty together.

Separate from penalties, HMRC charges interest on any SDLT that remains unpaid after the 14-day deadline. The current late payment interest rate for SDLT is 7.75%.⁶ Interest accrues from the day after the deadline until the tax is paid in full. On a £20,000 SDLT liability, a six-month delay adds roughly £775 in interest before any penalties are counted.

Appealing a Penalty

You can appeal a late filing penalty if you had a reasonable excuse for missing the deadline. HMRC sets a high bar: the excuse must have genuinely prevented you from filing the return yourself or arranging for someone else to file it. Accepted examples include a solicitor suffering a serious medical emergency or a posted return being lost due to postal disruption. Forgetting or being unaware of the deadline does not qualify. Appeals must be sent to HMRC within 30 days of the penalty notice, either by letter or using form SDLT46.⁷

Amending a Return and Claiming Refunds

HMRC gives you 12 months from the filing date to amend your return. The filing date is 14 days after the effective date of your transaction, so if your purchase completed on 1 March, the amendment window closes around mid-March of the following year.¹ Minor corrections like spelling mistakes or wrong vendor details can be made by calling the SDLT helpline. More significant changes, such as adding or removing a buyer, require a written request with a copy of the contract.

If you overpaid SDLT and the 12-month amendment window has passed, you can make a formal overpayment relief claim within four years of the effective date of the transaction. The claim requires the original UTRN, the amount paid, and the correct amount you believe was due. One common scenario is reclaiming the higher-rate surcharge after selling a previous main residence. In that case, you have three years from the new property’s purchase date to sell the old one, and then 12 months after the sale to file the refund claim.²
