Stamp Taxes calculator and stamp duty land tax on lease transactions calculator

Budget 2008 changes

These calculators are being updated to reflect the recent Budget changes. You can still use them but you might not get an accurate answer if your transaction relates to:

  • the grant of a lease
  • acquisition of shares

The tax/duty payable may be less when the changes are taken into account.

The Stamp Taxes calculator and the stamp duty land tax lease calculator are available for you to calculate your stamp duty land tax liability and where appropriate the Net Present Value (NPV) for lease properties. Both calculators have been updated to include those changes announced in the 2006 Budget.

In accordance with the Budget on 22 March 2006, both the Stamp Taxes calculator and the lease calculator deal with pre and post budget calculations.

The calculator tool cannot be used for any transaction that includes a mixed disadvantaged areas relief (DAR) element. This rule applies where the property itself is mixed use, or where there is more than one property involved. The tool will give an incorrect answer in these cases. We apologise for this inconvenience.

Backdating a renewal lease

In the limited circumstances in which paragraph 9A applies the earlier start date should be entered as the effective date on the Lease Calculator.

When completing the SDLT1, Q4 should be the date the new lease was granted.

On the expiry of a lease often the tenant remains in occupation while negotiations for a new lease take place and then after a time a new lease is granted.

The term of this new lease is sometimes expressed to commence from the day after the expiry of the old lease. The normal rule in England, Wales and Northern Ireland is that the term of a lease cannot commence earlier than the date the lease is granted.

Finance Act 2006 disapplies this rule where the ‘backdating’ described above takes place so that for stamp duty land tax (SDLT) purposes the term of the new lease commences on the date stated in the new lease. This treatment applies only where the old lease was subject to SDLT when originally granted. This change applies where the new lease is granted on or after 19 July 2006.
