What happens if HMRC loses or damages your SDLT return?
If HMRC loses or damages your stamp duty land tax return after you send it, you may face a real problem. HMRC may treat it as never received. But if you can prove you paid, it should not charge you twice.
What this rule is about
Someone may lose, destroy or damage a paper SDLT return so badly that HMRC cannot read or use it. Section 82 covers that situation. It also covers other tax documents sent to HMRC.
The point is simple. A missing form should not make you pay the same tax twice.
What the official source says
HMRC’s manual says it uses this rule when an SDLT1 is lost or damaged before its details reach the Central Processing Unit, even though the sender has already sent it to HMRC. That is guidance, not the full wording of the law.
- The return or document must have been sent to HMRC.
- It must be lost, destroyed or unusable.
- HMRC may then treat the return as not delivered.
- If tax is charged again, proof of earlier payment can lead to relief.
What this means in practice
Keep evidence that you sent the return and paid the tax. Once it has recorded the details, HMRC’s manual says it will give credit for tax paid when you sent the original return.
- Keep a copy of the completed return.
- Keep payment confirmations and bank records.
- Keep delivery evidence and HMRC references.
How to analyse it
Start with facts, not assumptions. Ask whether you can show what happened to the original return and payment, whether HMRC recorded its details, and whether you paid the tax already.
- Was a return sent to HMRC?
- Has it been lost, destroyed or made unreadable?
- Did HMRC record its details before that happened?
- Can you prove that tax was already paid?
Example
As an illustration, Mina sends her SDLT1 and pays the tax on time. HMRC damages the form before it records it. If HMRC treats it as missing and asks for tax again, Mina can use her payment evidence to show that she has already paid.
Why this can be difficult in practice
People often focus on finding another copy of the form. Payment evidence may matter just as much, especially when HMRC’s records do not show the original return and the evidence does not clearly identify the transaction.
- A damaged form may be unreadable but still exist.
- Sending evidence may not prove payment.
- Payment evidence may not identify the right transaction.
Key takeaways
- HMRC can treat a lost return as not delivered.
- Keep proof of both filing and payment.
- Earlier tax paid should not be charged twice.
