Forms and guidance to help you fill in and send HM Revenue and Customs (HMRC) your Stamp Duty Land Tax (SDLT) paper return.
You don’t pay SDLT if you buy a property in:
Fill in the SDLT1 return
You can file paper SDLT returns, but filing SDLT returns online is faster, more secure and lowers the risk of errors or incomplete returns. If you’re not represented by a solicitor or an agent, you must use the paper return.
For most straightforward cases, such as simple residential conveyances, the SDLT1 is all you’ll need. Order the SDLT1 online or by phone.
Send the completed SDLT1 together with payment of any SDLT that’s due on the transaction. No other paperwork is needed as the SDLT1 includes a payslip.
For more complicated transactions you may need to fill in more forms.
Each SDLT1 form and payslip has its own Unique Transaction Reference Number (UTRN) printed on it, so you can only use it for that particular transaction.
You can’t use photocopies of the SDLT return for different transactions.
See the SDLT1 guidance notes to help you fill in the paper return and forms.
HMRC will reject returns (SDLT1, 3 or 4) that don’t include a valid local authority code.
Transactions that need extra forms
You may have to fill in extra forms as well as the SDLT return. These are:
- SDLT2 if there are either more than 2 buyers or more than 2 sellers
- SDLT3 if either more than one property is bought or, there’s only one property but you can’t fit all the address details into the space given on the SDLT1 form
- SDLT4 if there’s a complicated lease, multiple grants of lease or a complicated commercial transaction
Order extra forms
Order forms SDLT2, SDLT3 and SDLT4 online or by phone.
SDLT 2: more than 2 purchasers or vendors
If there are more than 2 buyers or sellers fill in a separate form SDLT2 to give details of additional sellers or buyers.
If the number of additional sellers or buyers combined is more than 99, complete a schedule for the rest.
The schedule should include all the details asked for on form SDLT2.
SDLT 3: more than one property
When the transaction involves more than one property, fill in form SDLT1 and form SDLT3 for each additional property.
If there are more than 100 properties in total, complete a schedule for the rest.
The schedule should include all the details asked for on form SDLT3.
SDLT4: complicated leases, commercial transactions and some residential situations
Fill in form SDLT4 as well as form SDLT1 if any of the following applies:
- the land or property transaction is part of a business sale agreement
- the buyer is a company
- you’ve asked HMRC for advice on how the law applies to the transaction, using Clearances and Approvals 1 (CAP1), or another route
- any part of the consideration is dependent or uncertain
- arrangements have been made with HMRC under the deferment provisions
- there are mineral rights reserved
Check if you’ll need to fill in this form if the transaction:
- is the grant of a new lease or exchange of missives of let
- relates to the grant of multiple leases
Fill in an extra form for each lease. If the transaction involves more than 100 properties, complete a schedule for the rest of the properties.
The schedule must include all the details asked for on form SDLT4 and in SDLT4 guidance notes.
When you submit your return, if it’s correct and complete, you’ll get a SDLT5 certificate. Post it to the Land Registry with your application for registration.
Avoid mistakes and delays when filling in the paper return
When HMRC gets your SDLT return they’ll check to make sure the information you’ve given is clear, correct and complete.
If anything’s missing, wrong or unclear, they’ll write to you using form SDLT8 for the correct or missing information and won’t send you a SDLT5 certificate until you’ve given it.
Filling in your SDLT return online will make sure your return is correct and complete, as you can’t submit it if it isn’t.
You also avoid the risk of missed filing deadlines, penalties and late payment charges that can happen if you make a mistake on a paper return.
When and where to send the return
In case of postal delays, allow at least 3 working days for your return to reach HMRC.
You must send HMRC your SDLT return and any tax due within 30 days of the effective date of the transaction to:
BT Stamp Duty Land Tax
HM Revenue and Customs
Use this address for submitting your SDLT1 return only.
You shouldn’t include any other correspondence with the SDLT return as this may delay HMRC sending you the SDLT5 certificate.
Send any other correspondence to the Stamp Duty Land Tax Office.
Pay your SDLT
Pay SDLT electronically using the reference number shown on your payslip, even if you don’t file your SDLT return online.
The UTRN for the transaction is in the ‘reference’ box on the payslip. Keep this safe because:
- you’ll need it to pay your SDLT
- HMRC will use it to trace your SDLT return and payment if you have a query
If you made a mistake on your return
How to amend a SDLT return within 12 months of the filing date
For other more substantial errors (for example, where the underlying identity of any buyer or the property details needs changing or where the new effective date is after the date of notification) you must:
- order a new SDLT1 and file a new return with the correct information
- write to the Stamp Duty Land Tax Office giving reasons for the new return and give the UTRN of the incorrect and correct returns
Amend by post
Write to the Stamp Duty Land Tax Office and explain what you want to amend. Include a copy of your SDLT return. The Stamp Office will write back confirming the amendment and tell you if you need to take any further action.
Amend by phone
Call the Stamp Duty Land Tax Helpline and give your UTRN to the adviser. Tell them what to correct. If they can’t make the amendment over the phone, or if a repayment is due because of your amendment, they’ll tell you what to do next.
If the amendment means you paid the wrong tax
If you paid the wrong tax you can:
- ask for a repayment if you’ve paid too much
- pay the amount you’ve underpaid right away if you’ve not paid enough - you pay interest on this from the filing date, when the tax was originally due
HMRC can make an enquiry into your amended return up to 9 months after you’ve made an amendment. If you got a repayment but the amount you were repaid wasn’t due, you must pay it back.
Amend a return when HMRC opens a formal enquiry
You can still amend your return after HMRC has started to make an enquiry but your amendment can’t take effect until after the enquiry is finished.
If, at the end of the enquiry, HMRC finds that your return is incorrect you’ll be told how to amend it.
HMRC will take into account any amendment you’ve already asked for.
If you’ve made a mistake on your SDLT return that’s more than 12 months old
HMRC Stamp Taxes can amend a buyer’s name, but can’t make amendments that change either the underlying identity of any buyer or the property details.
You can’t correct any other mistakes on your SDLT return more than 12 months after the filing deadline. You may still be able to claim a refund if the mistake means you’ve paid too much SDLT.
To ask HMRC to amend a return older than 12 months write to the Stamp Duty Land Tax Office explaining what the error is, how it happened. Include a copy of your original return.
If you’ve sent a return in error or sent a duplicate return
Include the following information:
- the UTRN
- the reason why they should disregard the return
- whether you have used the SDLT5 certificate to register the transaction
If you’ve filed an unnecessary or duplicate return and incurred a penalty charge that you want to dispute, appeal in writing. This must be within 30 days of the date on the penalty notice.
Claim a refund
Claiming a refund of the higher SDLT rates for additional properties
If you have paid the higher SDLT rates for additional properties on the purchase of a new main residence, and go on to sell your previous main residence within 3 years of paying the higher rates, a refund is available.
The refund is for the amount of SDLT paid above what would have been charged had the property not been an additional residential property.
A refund must be claimed within 3 months of the sale of the previous main residence or within 12 months of the filing date of the return, whichever comes later.
To claim a refund you can complete an online form.
Claiming a refund in other circumstances
The deadline for claiming back tax you’ve overpaid is 4 years from the effective date of the transaction. This is usually the completion date.
Claim the refund by writing to the Stamp Duty Land Tax Office. Give the UTRN and include a copy of the original SDLT return with your claim and:
- explain why you think you’ve overpaid
- say what parts of the SDLT return were wrong
- give revised figures
HMRC will pay the refund to you unless you write to give your permission to pay it to someone else (for example, your solicitor or agent).
If you’ve underpaid SDLT
If you’ve underpaid SDLT tell HMRC as soon as you realise.
If you don’t, you may have to pay a penalty. You’ll normally have to pay interest on any SDLT you pay late.
Add extra details to a paper SDLT certificate
If the mistake on the SDLT certificate is small, you can phone the Stamp Taxes Helpline and ask an adviser to amend the SDLT return. They’ll send you the correct certificate.
You can make the following changes by phone. Corrections to:
- buyer details on either questions 59 or 70 of the SDLT1 paper return
- question 26 or 72 of your paper return if you’ve got a SDLT8 telling you you’ve made a mistake
- a spelling error in the property address
For other errors you’ll need to write to the Stamp Duty Land Tax Office to ask them to correct it. For example, write if you want to:
- add or remove a buyer
- claim a refund
- change the number of titles.
Include a copy of the SDLT return with your letter.
