Lloyds and Halifax SDLT Incentives: Managing Cashback and Payment Risk

Originally published March 2014. Updated October 2026.

A mortgage incentive described as “help with stamp duty” can create a practical problem for the conveyancer: will the money actually be available when the tax needs to be paid?

The buyer may assume that the lender will take care of the cost. The conveyancer may discover that the incentive is payable only after completion, subject to conditions or through a separate payment process.

That difference between an expected benefit and available funds deserves attention before exchange. It should also be addressed in the firm’s CQS Stamp Duty Land Tax Policy.

The original Lloyds Banking Group and Halifax example

Our original 2014 article considered a Halifax mortgage promotion within Lloyds Banking Group. It described an incentive linked to the buyer’s SDLT cost, with payment to the conveyancer expected after completion.

The concern was that a conveyancer might rely on that later payment to fund the buyer’s tax liability, leaving the file dependent on the lender’s payment arriving as anticipated.

That promotion was historical. The offer dates, eligibility conditions and tax bands discussed in the original article should not be treated as current. For any present transaction, check the actual mortgage offer and incentive terms.

The enduring lesson is about funding and timing: a promise of cashback does not establish that the money is available to pay SDLT.

A mortgage incentive does not extend the SDLT deadline

Where an SDLT return is required, it generally needs to be submitted within 14 days of the transaction’s effective date, and any tax due must also be paid within that period.

The effective date is usually completion, but substantial performance can bring it forward. A notifiable transaction may require a return even where no tax is payable.

A lender’s cashback timetable does not alter that deadline. Firms should check HMRC’s current SDLT payment guidance and allow for payment processing time rather than treating the last day as a target.

SDLT applies in England and Northern Ireland. Welsh transactions require a separate approach to Land Transaction Tax, and Scottish transactions to Land and Buildings Transaction Tax.

Check how the incentive will be paid

Before including an incentive in the funding arrangements, establish:

• Eligibility: does the client and proposed transaction qualify?
• Amount: is the payment fixed, capped or linked to a stated cost?
• Recipient: will it be paid to the borrower, conveyancer or another party?
• Timing: is it included with the advance or paid separately after completion?
• Conditions: what information or action is needed before payment is released?
• Contingency: how will the tax be funded if payment is delayed or eligibility is disputed?

Record the answers and retain the supporting offer or written confirmation. Where the terms are unclear, obtain clarification before relying on the payment.

Check the precise lender and mortgage product. Membership of the same banking group does not justify assuming that Lloyds Bank and Halifax use identical incentive arrangements or conveyancing instructions.

Our Halifax conveyancing panel guide explains why the particular lender, firm and office should be identified correctly at the outset.

Make the funding position clear to the client

A completion statement should distinguish between money needed from the client and an incentive expected later.

If cashback will arrive after completion, explain whether the client must initially provide the full SDLT amount and how any subsequent payment will be accounted for.

For example, a buyer may expect a £1,000 cashback payment. If it will arrive only after completion, deducting it from the money requested from the client could leave the firm short of the funds needed for the tax payment.

The firm needs a documented funding arrangement that works without assuming the incentive will arrive on time. If the client cannot provide the required funds, escalate the issue before exchange.

Our earlier article on SDLT budgeting and avoiding a costly surprise before exchange considers the wider problem of buyers overlooking tax costs.

Separate the tax calculation from the funding arrangement

Establishing how SDLT will be funded is different from calculating how much is payable.

Do not assume that a payment marketed as “stamp duty cashback” reduces the buyer’s tax liability. Consider the nature of the arrangement and obtain appropriate advice where its tax treatment is unclear.

The calculation should be supported by the client’s circumstances, transaction documents and the applicable rules. Any relevant relief, surcharge or unusual arrangement needs its own assessment.

For drafting support, see the Stamp Duty Calculations policy wording in the Lexsure Knowledge Hub. Our guide to the 2026 Stamp Duty Land Tax Policy updates explains the related calculation review and pre-exchange controls.

Build the checks into your CQS SDLT policy

A practical SDLT procedure should identify who checks incentive terms, confirms the funding position, approves the calculation and monitors submission and payment.

It should also explain how staff deal with a missing payment or an unresolved funding shortfall. Allocation of responsibility matters particularly when the fee earner, accounts team and post-completion team handle different stages.

Retain evidence of:

• The incentive terms and any lender clarification.
• The SDLT calculation and professional review.
• The funding explanation given to the client.
• Receipt and allocation of funds.
• Return submission and payment confirmation.
• Any subsequent cashback receipt and reconciliation.

Manage the incentive without relying on it arriving late

The useful lesson from the 2014 example remains straightforward: establish the tax liability, confirm how it will be funded and keep control of the payment timetable.

A lender incentive may benefit the client. The conveyancing process still needs to work if that benefit is received later than expected.

This article provides general guidance. Check current tax rules, the mortgage offer and the relevant lender instructions for each transaction.
