How Much Is Stamp Duty in the UK in 2025?

When purchasing property in the UK, it’s mandatory to pay Stamp Duty Land Tax (SDLT), and the amount you pay depends on the value of the property. The higher the price, the higher the stamp duty. The tax applies to both residential and commercial properties, but the rates differ.

For first-time buyers, as of April 2025, the relief is available on properties up to £625,000. For properties priced between £300,000 and £625,000, a reduced rate of 5% applies. If the property is priced over £625,000, the discount does not apply.

What are the Changes in Stamp Duty for 2025?

Effective from 1 April 2025, several significant changes have been implemented in the Stamp Duty Land Tax (SDLT) system for England and Northern Ireland. These adjustments aim to address housing market dynamics and ensure a fairer distribution of the tax burden.

1. First-Time Buyer Relief Adjustments

• Nil-Rate Threshold Reduced: The nil-rate threshold for first-time buyers has been lowered from £425,000 to £300,000. This means that first-time buyers will pay 0% SDLT on properties up to £300,000.
• Relief Cap Reduced: The maximum property value eligible for first-time buyer relief has been capped at £500,000, down from the previous £625,000. Properties exceeding this value will not qualify for the relief.

2. Higher Rates for Additional Properties

• Increased Surcharge: The additional property surcharge has been increased from 3% to 5%. This surcharge applies to purchases of second homes and buy-to-let properties.
• Updated SDLT Rates for Additional Properties:

3. Non-UK Residents Surcharge

• 2% Surcharge Continues: Non-UK residents are subject to an additional 2% SDLT surcharge on top of the standard rates. This applies to all residential property purchases in England and Northern Ireland.

4. Temporary Relief Period Ends

• End of Temporary Threshold Increase: The temporary increase in the residential nil-rate threshold from £125,000 to £250,000 has ended. This change was initially implemented to support the housing market but was set to conclude on 31 March 2025.

These changes are designed to make the housing market more accessible for first-time buyers and to ensure that additional property purchases contribute a fair share to the tax system. For detailed information and to calculate your SDLT liability, please refer to the official HMRC guidance.

What Are the Stamp Duty Rates for Second Homes or Buy-to-Let Properties?

The rates for second homes and buy-to-let properties have been subject to an additional 3% surcharge over the standard rates. Here’s how it works:

For second homes or buy-to-let properties, you’ll pay the standard stamp duty on the first £125,000 and the additional 3% surcharge applies for every band above that, on top of the usual rates.

What Are the Exemptions and Reliefs for Stamp Duty?

Though you must pay stamp duty when purchasing property, exemptions and reliefs can reduce the amount or waive it completely.

Exemptions:

• Inherited property
• Divorce or separation
• Partnership dissolution
• Short leases
• Gifted properties

Stamp Duty Reliefs:

• First-time buyers: Relief available for homes up to £625,000 (with a reduced rate for homes between £300,000 and £625,000).

Is Stamp Duty Based on Completion or Exchange?

The completion date is used to determine the Stamp Duty and not the exchange of contracts.

Exchange of contracts refers to the situation where the buyer and seller have entered into the transaction legally.

Completion is done upon the issuance of an official handover of the property and acceptance of the property by the buyer. Stamp duty liability on completion (the effective date of the transaction) unless the contract has substantially been performed before (e.g., the buyer has taken possession or paid most of the price before completion).

Can You Pay Stamp Duty Before Completion?

Technically, you cannot submit the SDLT return before completion. However, you can ensure payment is made in advance by preparing it with your solicitor. They typically file the return on the day of completion but will have everything ready for the payment to be processed.

The 14-day deadline for submitting the SDLT return and paying the duty starts from the completion date, not the exchange of contracts. However, it’s advisable to have your solicitor prepare the payment in advance to ensure it’s ready to submit without delays.

How Do You Pay Stamp Duty?

File an SDLT return with HMRC and pay duty within 14 days of being completed. When you have a solicitor, agent, or conveyancer, they’ll normally submit your return and settle the tax on your behalf on the day of completion. Then they add their fees to the tax.

You will normally have your solicitor or conveyancer responsible for paying Stamp Duty on your behalf. They are more likely to file your return and remit the amount to be paid on the date of completion.

Whether or not you are required to pay tax on a property, you must submit a property tax return to HMRC. Failure to submit the return within 14 days of the completion of the transaction may lead to a fine. Remember, you can’t pay stamp duty using your personal credit card.

Can You Pay Stamp Duty in Instalments?

The SDLT payment is normally due within a 14-day time frame and in full after the completion of a property transaction. Nevertheless, HMRC provides a payment deferral facility to the qualified buyers. Yet, it is important to comply with all of the eligibility requirements, get permission, and comply with the agreed-upon instalment schedule.

To pay in instalments, you have to apply to HMRC, where they evaluate your financial position. On approval, you will be given a monthly payment schedule, but interest will be charged. That is usually less than the interest charged on credit cards. This is a bit flexible alternative that can help ease the burden on your bank account, but you must determine whether it fits your situation.

Can You Add Stamp Duty to Your Mortgage?

While you cannot directly add the stamp duty charge to your mortgage as a separate fee, you could borrow additional funds to cover the cost of stamp duty if your mortgage lender agrees. This will depend on your affordability and loan-to-value ratio (LTV). Borrowing extra money for the stamp duty could increase your monthly payments and overall loan amount.

If you do borrow more to cover stamp duty, bear in mind that the extra amount will be subject to interest throughout the mortgage term, and this will affect your loan-to-value ratio.

Can You Get a Stamp Duty Refund?

• Miscalculation of SDLT

What are the Implications of Not Paying Stamp Duty Tax?
