When you buy a house or land in the UK, there is a special tax that you will have to pay known as Stamp Duty Land Tax or SDLT. SDLT, what is it all about? How is it calculated? And many other common questions about it will be answered here.

Stamp Duty Reserve Tax

Stamp Duty Land Tax (SDLT)

A Stamp duty is a tax paid when buying a property or share in the UK. It depends on the property value and the buyer’s situation.

  • Stamp Duty Land Tax (SDLT): This applies to purchases of land or houses.
  • Stamp Duty Reserve Tax (SDRT): This applies to purchases of shares electronically.

How to Calculate Stamp Duty Land Tax? 

Stamp Duty Land Tax (SDLT) is payable when buying a house or land. Here is a simplified work: 

Threshold Below £125,000 = No SDLT; if the house costs above £125,000, you will pay SDLT on the amount exceeding this threshold.

Rates: The SDLT rates are gradual; the higher the price of the house, the higher the rate. 

For example, on the purchase of a house costing £350,000, the off-the-shelf part will charge 0% on the first £125,000, 2% on the next £125,000, and 5% on the balance of £100,000.

Example: 

Facility Price: £350,000

SDLT Calculation:

0% on the first £125,000= £0

2% on the next £125,000= £2,500

5% on the last £100,000= £5,000

Total SDLT= £7,500

What is Stamp Duty Reserve Tax?

Stamp Duty Reserve Tax (SDRT) is an electronic tax on share purchases. This kind of tax does not ask for stamping a document with a paper stamp. Such cases are usually 0.5% of the share purchase price.

An Example: 

Share Purchase Price: £1,000 

Calculation for SDRT: 0.5% of £1,000 = £5 

Total SDRT: £5. 

How Much is Stamp Duty Land Tax? 

SDLT depends on the price of the house and whether that house is primary or secondary. A house bought worth £350,000 as a main home is charged the SDLT as above. But, if it is the second home, you would incur an additional 3% on top of the usual rates.

Is Stamp Duty Tax Deductible for CGT? 

The gains tax is the former capital gains tax applicable as profit brought forth through sales of shares and houses. Stamp duty is indirectly not deductible from CGT but may form part of the cost of a property for the calculations of CGT. In doing so, it can minimize the yield profit, which in turn minimizes the amount of CGT tax payable. 

Can You Deduct Stamp Duty from Capital Gains Tax? 

Stamp Duty may not be deducted directly from CGTs but will be added to the asset cost. Buying a house for £200,000 in December and also paying £10,000 in SDLT means the total cost is £210,000; this will represent the amount at which it will be sold at £300,000 with a profit of £90,000 taxable under CGT.
