Reforms to Stamp Duty Land Tax which kicked in at midnight caused mayhem in much  of the market yesterday.

Almost before George Osborne had sat down, the announcement triggered an intense wave of activity at estate agents, lawyers and accountants – with deals, particularly in London, being hurried through to exchange before the clock struck twelve. Buyers of properties priced at between £1.5m and £2m had up to an extra £53,750 at stake – a rise of 54% on their anticipated bills.

There were tales of advisers hauling their clients off golf courses to get exchanges through, said the BBC last night.

But agents everywhere yesterday afternoon reported a surge of calls from buyers at all levels wanting to know what the reforms meant for them.

The downright winners are those paying less than £937,500 who were handed an early Christmas present if they are exchanging this week. However, there could also be winners who have exchanged but not yet completed.

The losers are those paying more. It was those potential losers and their advisers who were yesterday pressing for exchange by midnight.

Buyers exchanging before then, regardless of when they complete or how much they are paying, can choose to pay SDLT at either the old or new rate.

From today, the new rates apply on all exchanges.

One London agent, Haus Properties, was among those burning the midnight oil.

Jamie Lester, who heads up the business, said yesterday afternoon: “We were due to exchange on a £2m property this week and the buyer is now pushing to do this today.

“I expect a lot of lawyers will be working late into tonight to exchange on sales between £1.5m and £2m.”

However, other losers are buyers of more ordinary-priced properties who have only just completed – typically last Friday, as the last Friday of a month is the busiest for completions.

One conveyancing firm, Blacks Connect – also inundated with calls yesterday afternoon – said of recent purchasers: “Most will have lost out.”

However, yesterday agents were also busy liaising on deals where there have been exchanges but not completions – and where, under the ‘midnight’ rules,  the buyer can now choose to pay less SDLT.

Announcement of the new SDLT regime sent a particular shock wave through the London market as agents and buyers reached for their calculators.

For example, the purchaser of a £1.9m property would have paid £95,000 under the old structure. Under the new rules, they will be paying £141,750.

In prime parts of London, said Peter Rollings of Marsh & Parsons, 56% of property is worth £1m or more.

Another agent, Cluttons, said that in Clapham, someone buying a two-bed flat would be £18,750 better off, but someone buying the same type of property in Chelsea will be £35,000 worse off.

Liz Peace, of the British Property Federation, said: “A little bit more notice would have been helpful as the sector will have had to get to grips with the changes by midnight. The rapid speed of implementation no doubt reflected any rapid moves to avoid paying.”

At a glance:

The old ‘slab’ system:

0% on properties up to £125,000

1% on properties from £125,001 to £250,000

3% on values between £250,001 and £500,000

4% on properties between £500,001 and £1m

5% on properties between £1m and £2m

7% on properties above £2m

 

The new system:

No SDLT payable at all on properties up to £125,000

The first £125,000 on properties to be free of SDLT

Then payable at 2% payable on the portion up to £250,000

Payable at 5% on the portion up to £925,000

Payable at 10% on the portion up to £1.5m

Then payable at 12% on the portion over that amount.
