The stamp duty problem

Buyers overpay stamp duty every day. It is your opportunity to show them you are looking out for them.

Stamp Duty Land Tax calculations are more complex than most buyers realise. Multiple property ownership, mixed-use properties, uninhabitable properties, property condition and a range of reliefs and exemptions mean many buyers pay more than they should - or do not claim reliefs they are entitled to. Cornerstone identifies and recovers those overpayments on a no-win, no-fee basis.

"Our buyer paid stamp duty on a property that qualified for a relief they did not know about."

SDLT reliefs for first-time buyers, mixed-use properties, uninhabitable condition and multiple dwellings relief are not automatically claimed. Buyers who are not specifically advised often miss significant entitlements.

"We are not giving our buyers anything additional that makes them want to refer us."

Vendors and buyers who feel genuinely looked after refer agents. A service that finds them money back on one of their biggest transaction costs is a tangible, memorable thing to offer - and it costs the agent nothing.

"The sale nearly fell through because the buyer could not find the additional funds."

Where a stamp duty saving frees up buyer budget, it can ease the affordability pressure on a transaction that was at risk. Cornerstone describes this as potentially freeing up further budget for the buyer to aid the sale.

"We want to offer clients more than just finding them a property."

The agencies with the strongest referral businesses are the ones that offer the most rounded service around the transaction. SDLT advice through Cornerstone is one way to extend your service without adding to your team's workload.

How Cornerstone Tax works for estate agents and their clients

Six things to know about how the Cornerstone service works.

Cornerstone's service is designed to be as simple as possible for estate agents to introduce. No training, no onboarding, no overhead. Just an introduction and a potential saving for your client.

1

SDLT review on referral

Estate agents refer their buying clients to Cornerstone for a stamp duty review at any point in the transaction. Cornerstone reviews the purchase and identifies whether any SDLT reliefs, exemptions or corrections apply to reduce the liability.

2

No-win, no-fee service

Cornerstone only charges when they achieve a saving. Their standard success fee is 25% of whatever they save the client. If no saving is possible, neither the agent nor the buyer pays anything. The risk sits entirely with Cornerstone.

3

Fully indemnified advice

All advice provided by Cornerstone is fully indemnified by their professional indemnity insurance. This means the estate agent introducing the service is not exposed to liability for the advice given - it is Cornerstone's professional responsibility.

4

No onboarding required for agents

There is no training programme, no onboarding process and no system to learn. Estate agents simply introduce their buyers to Cornerstone. The Cornerstone team handles everything from initial review to any HMRC submissions required.

5

Helping push transactions through

Where a Cornerstone SDLT saving frees up additional buyer budget, it can help a transaction that was under financial pressure complete. The saving can be the difference between a buyer who can afford the stamp duty and one who cannot.

6

Private clients, solicitors and accountants

Cornerstone serves estate agents' clients directly, and also works with solicitors and accountants. This means they are often already known to the professional advisers involved in a transaction - streamlining the referral process.

How estate agents introduce Cornerstone to their buyers

From introduction to outcome - three simple steps.

The Cornerstone process is deliberately simple for estate agents. Your team introduces the service. Cornerstone handles everything else.

1

Mention Cornerstone to your buyer

At any point in the transaction, mention to your buyer that Cornerstone offers a no-win, no-fee SDLT review. There is no training required for this conversation - just an awareness that the service exists and may save them money.

2

Cornerstone reviews the purchase

Cornerstone reviews the specific purchase details - property type, condition, use, buyer circumstances - and calculates whether any SDLT reliefs or corrections apply. This review is conducted by qualified tax specialists.

3

Saving recovered (where applicable)

Where a saving is identified, Cornerstone handles all communication with HMRC and the relevant paperwork. The buyer receives the saving minus Cornerstone's 25% success fee. The estate agent has added value to the transaction at no cost.

4

No saving - no charge

If Cornerstone cannot identify a saving, neither the buyer nor the agent pays anything. The review has cost your client nothing and your team nothing.

5

Referral relationship maintained

The buyer remembers that their estate agent found them a specialist who saved them money on their stamp duty. That memory contributes to the referrals and repeat business that makes up a significant proportion of every successful agency's instructions.

Frequently asked questions

Common questions from estate agents.

What types of property purchase are most likely to generate a stamp duty saving?
Properties with potential SDLT reliefs include: mixed-use properties (part residential, part commercial), uninhabitable properties where the residential rate may not apply, purchases where multiple dwellings relief applies, and situations where first-time buyer relief was not correctly claimed. Cornerstone's review covers all available reliefs and exemptions.
Is there any cost or risk to the estate agent?
No. There is no cost, no onboarding and no overhead for the estate agent. Cornerstone's no-win, no-fee model means neither the agent nor the buyer pays anything unless a saving is found. All advice is fully indemnified by Cornerstone's professional indemnity insurance.
Does the agent get any commission for referring clients to Cornerstone?
Cornerstone's standard model is that the buyer benefits from the full saving minus Cornerstone's 25% success fee. If you would like to understand the commercial arrangements for referral partnerships in more detail, contact the Cornerstone team through the Kerfuffle network.
How does a buyer access the Cornerstone review?
Estate agents introduce their buyers to Cornerstone directly. Cornerstone then contacts the buyer to begin the review. The whole process is handled by Cornerstone - the estate agent simply makes the introduction.
Can Cornerstone review a stamp duty calculation after completion?
Yes. SDLT reviews and corrections can often be made after a purchase has completed if the buyer believes they may have overpaid. Cornerstone can review historic transactions as well as those currently in progress.
