Your Situation in 2 Minutes

Eight questions. At the end you'll see your estimated refund and an honest assessment of whether your case is one you can file yourself or one that's worth professional handling. No email or phone number required.

Higher Rate SDLT Refund Assessment

Step 1 of 8

Did you buy a new main home before selling your previous one?

This is the situation the relief is designed for — you completed the new purchase first and paid the higher rate surcharge, with the previous home still owned at that point.

Have you now sold the previous home?

The refund only crystallises once the previous home is sold. If you haven't sold yet, you can still see your projected refund.

What was the completion date of the new main home purchase?

This determines which surcharge rate applied (3% before 31 October 2024; 5% from 31 October 2024).

What was the purchase price of the new main home?

The full chargeable consideration. The surcharge applies to the entire amount.

Was the previous property unambiguously your main residence?

HMRC looks at where you actually lived as your primary home — utilities in your name, council tax, post addressed there, electoral roll. Not just what was on the title.

Has the ownership arrangement changed between purchase and sale?

Examples: separation or divorce affecting joint ownership; equity release; remortgage that altered the share; transfer between spouses or to a trust.

Were any of these features part of your transaction?

Tap any that apply, or "None of these" if none do. These are the situations where claims most often run into difficulty.

Are you a UK resident for SDLT purposes?

Non-residents pay an additional 2% surcharge. This is a separate relief from the higher rate refund and may also be reclaimable.

The Two Groups

The questionnaire above will tell you which group your case falls into. Here's the underlying logic — most claims sit on the left; the cases that genuinely benefit from professional handling sit on the right.

You can DIY if…

  • Both properties were unambiguously your main residence
  • You sold the previous home within 3 years of the new purchase
  • Ownership was straightforward — sole, or joint with spouse
  • No additional properties complicate the position
  • Dates and documentation are clear and consistent
  • HMRC hasn't queried your original return

Cost: £0. Read my DIY guide or go straight to HMRC's page.

Consider professional handling if…

  • The previous property's status as main residence is debatable
  • Joint ownership has changed since purchase (separation, divorce, equity release)
  • You own additional residential properties — including abroad
  • You bought through a company, trust, or partnership
  • You retained an interest in the previous home after sale, or sold to family on non-arm's-length terms
  • HMRC has already opened an enquiry or proposed a penalty

My fee: from 7.5% of the refund. No win, no fee. If HMRC subsequently claws back the refund, I refund my fee in full.

Why this matters — recent tribunal decision

HMRC is actively penalising incorrect claims, and the Upper Tribunal has just confirmed its powers

In Cox v HMRC (decided 7 January 2026), the Upper Tribunal upheld penalties of £32,405 against two taxpayers who had claimed Business Asset Disposal Relief in their self-assessment returns in circumstances where the relief did not in fact apply. The taxpayers were a financial adviser and a company director. They had taken professional advice on the underlying transaction. The penalties were imposed at the minimum 15% rate for careless inaccuracy under Schedule 24 of the Finance Act 2007, and HMRC's refusal to suspend those penalties was confirmed on appeal.

The same Schedule 24 regime applies to SDLT refund claims. A claim submitted on form SDLT16 is a "document … in connection with a claim for repayment of tax" under paragraph 1 — and an inaccurate claim that fails reasonable care can attract penalties of 15% to 30% of the lost revenue on top of the refund being clawed back. HMRC has been actively pursuing this in the SDLT context, particularly on volume-firm claims that don't properly evidence the main-residence position.

The point isn't to scare anyone — most claims are fine. The point is that "the form looks straightforward" is not, by itself, a defence. If your situation has any of the complicating features above, the penalty exposure is real and recently confirmed.

Where Volume Reclaim Firms (and DIY Filers) Most Often Slip Up

The Cox case is a useful guide to where the regime bites. The taxpayers had advice — but it wasn't specific advice on their changed circumstances. That same failure mode shows up repeatedly in SDLT refund claims, particularly on the points below. If any of these apply to your situation, the claim deserves more than a form-filling exercise.

  • Main residence status — HMRC looks at where you actually lived, not just title. Patterns of occupation, council tax, utility bills, voter rolls and correspondence all matter.
  • Retained interest after sale — paragraph 3(7)(ba) of Schedule 4ZA requires that immediately after the disposal, neither you nor your spouse or civil partner has a major interest in the sold dwelling. The test is about retained ownership, not who the buyer was — a sale to a sibling at full market value with no retained interest is fine, but any retained beneficial interest (option to repurchase, side-letter, undisclosed share) will disqualify the claim regardless of who the buyer is.
  • Joint ownership changes — if ownership shifted between purchase and sale (separation, divorce, equity release, remortgage), the relief rules become significantly more nuanced.
  • Additional dwellings — buy-to-lets, inherited shares, or properties held abroad can disqualify the claim if not properly addressed.
  • Company, trust, or partnership ownership — Schedule 4ZA is stricter where the buyer is not a natural person, and a generic claim form will often miss this.

FAQ

Why are you telling me I might not need you?

Because for most people, that's the truth. The replacement-of-main-residence refund is one of the more straightforward SDLT reliefs to claim, and HMRC has built a clear process for it. Pretending otherwise would be dishonest, and the cases I genuinely add value to are the complex ones — where being upfront about the simple cases is what builds the trust to handle the harder ones.

Is there a step-by-step DIY guide?

Yes — I've written one. Read the DIY guide here. It covers the form, the evidence HMRC actually wants to see, the time limits, and the common mistakes. Use it alongside HMRC's official page.

What's the time limit for claiming?

You must sell the previous main residence within 3 years of buying the new one (Finance Act 2003 Schedule 4ZA paragraph 3(7A)(a)). The refund claim itself must be filed within 12 months of the sale of the previous home, or 12 months of the original SDLT filing date, whichever is later (paragraph 8(3)).

If you're outside these windows, claims under overpayment relief are sometimes possible but the rules are stricter. Get in touch if you're close to or past the deadline.

How much can I expect to reclaim?

The refund is the higher rate surcharge portion of the SDLT you originally paid. For purchases on or after 31 October 2024, this is effectively 5% of the full property price. For earlier purchases, it was 3%. The questionnaire above gives you an instant figure based on your specific date and price.

What happens if HMRC opens an enquiry into the claim?

If I prepared the claim, I handle the enquiry correspondence as part of the original engagement. The whole point of professional handling is that the claim is built to withstand review at the time of submission, so enquiries are uncommon on properly prepared cases. If one does come up, you're not left to deal with it alone.

If you submitted the claim yourself and HMRC has subsequently raised concerns or proposed penalties under Schedule 24, get in touch — I take on enquiry-stage cases as well.

How are your fees calculated?

My fee is from 7.5% of the refund, no VAT. Most claims are at the floor; cases that involve significant additional analysis, drafting, or correspondence with HMRC may attract a higher fee, which I quote and agree with you in writing before any work starts.

HMRC pays you, you pay me. The refund is paid directly into your bank account by HMRC — I never handle client money. My fee is then invoiced to you afterwards.

Clawback guarantee: If HMRC subsequently claws back the refund, I refund my fee in full.

Are there any upfront fees?

No. The initial assessment is free. If we proceed, my fee is taken only after HMRC has paid the refund into your account. No refund, no fee. The refund is paid directly to you by HMRC — I never handle client money.

How long does the process take?

Initial assessment: usually within 24–48 hours of you sending the details. Preparation and submission once we have the documents: typically a week or two. HMRC processing: currently around 6 to 9 weeks for straightforward claims, sometimes longer.

Do you handle other SDLT reclaims?

Yes — mixed-use property reclaims, uninhabitable property reclaims, and various other overpayment situations. I also do indemnified letters of advice from £350 (no VAT) for complex purchases where your conveyancer needs a formal SDLT opinion before completion. See landtaxadvice.co.uk for the full range.
