Buyers are overpaying the stamp duty surcharge, says ...

National estate agency Jackson-Stops claims that the 3% stamp duty surcharge on additional homes is still confusing buyers, despite being in operation for over two years.

The firm says that the most common reason for buyers overpaying their stamp duty bill is due to misunderstanding of the 3% surcharge.

The additional stamp duty requirement, introduced in April 2016, applies to the purchase of second homes and buy-to-let properties.

The agent cites figures from Her Majesty's Revenue & Customs (HMRC) showing that at least 15,700 buyers overpaid stamp duty in the last year. HMRC has also said that it receives calls about the stamp duty surcharge every day.

Jackson-Stops gives an example where it saved a buyer from paying an additional £18,000 on the purchase of a £600,000 home as they were not required to pay the surcharge. This left the buyer's bill at £20,000 rather than £38,000 had the surcharge been applied.

"Some assume that owning any other property triggers liability for [the stamp duty surcharge]," says a spokesperson for Jackson-Stops.

"But it should not apply when replacing your “principal place of residence” and, if you move before selling your previous home, you have three years to claim the 3% surcharge back, when you do."

The agency cites another example of the owner of a buy-to-let property who was not required to pay the stamp duty surcharge after selling their main residence to live abroad, returning and then buying a replacement property as a main residence.

It says it also knows of a buyer of a four-bed cottage with one-bed studio who mistakenly paid a £20,000 surcharge, but was able to claim it back.

Another issue to be aware of is mixed-use properties, says the agency.

Despite higher Capital Gains Tax liabilities, properties that include offices or agricultural land can fall under commercial stamp duty rates.

Jackson-Stops refers to a buyer of a farmhouse with 50 acres this applied to where the stamp duty difference was £186,750.

Purchasing of multiple dwellings also often causes confusion, according to the agency.

"The process takes into account the tax that would be paid on the individual average price, as opposed to taxing, say, five £200,000 houses as if they were a single £1 million property," it says.

"It applies a minimum rate of 1% but, again, can make a substantial difference. Ultimately, HMRC deals with all purchases on a case-by-case basis."
