Stamp Duty Planning: How to Avoid SDLT Overpayment Before You Buy

Stamp Duty Land Tax (SDLT) is one of the biggest costs buyers face after purchasing property in England and Northern Ireland. But did you know that thousands of people overpay stamp duty every year - simply because they don’t understand how the rules apply to their property?

At SCA Tax, we’ve helped countless buyers reclaim overpaid stamp duty. But even better than a refund is planning ahead to avoid the overpayment in the first place.

Why Stamp Duty Overpayments Happen

Stamp duty is not always straightforward. The way your property is classified can dramatically change your SDLT bill. Common causes of stamp duty overpayment include:

• Mixed-use properties: Buying a shop with a flat above? You may qualify for mixed-use rates instead of residential.
• Probate property purchases: Acquiring a property through probate or inheritance can raise unique SDLT issues. Without expert guidance, you could pay more tax than necessary.
• Corporate and group relief – Business or group structure purchases often qualify for SDLT relief, but many buyers (and even solicitors) overlook it.
• Second homes and buy-to-let purchases: The surcharge often catches buyers by surprise.

Without expert guidance, it’s easy to pay thousands more than necessary.

Examples of Stamp Duty Mistakes

• Mixed-use miscalculation: A family purchased a building with both commercial and residential elements but paid the full residential rate. Proper SDLT planning could have saved them £15,000.
• Probate property purchase: A property investor bought a probate property through their business. Because the property came via probate, SDLT wasn’t actually due, yet they were charged incorrectly. With expert help, they recovered £25,000.

These errors are far more common than people think.

The Benefits of Stamp Duty Planning

Instead of waiting until after you’ve overpaid and applying for a stamp duty refund, you can plan ahead to make sure you:

• Pay the correct rate from the start
• Take advantage of all available reliefs
• Avoid unnecessary surcharges
• Save thousands in upfront costs

A pre-purchase SDLT review can be just as valuable as a survey or legal check and protects your finances before you commit.
