LBTT Calculator
Work out the Land and Buildings Transaction Tax on a property in Scotland. It checks whether the 8% Additional Dwelling Supplement applies from what you'll own after buying, covers first-time buyer relief, and handles mixed-use and six-or-more-dwelling purchases.

How to calculate LBTT on a buy-to-let
Work out LBTT band by band. If ADS applies, add 8% of the full price. A buy-to-let bought by someone who'll own more than one dwelling pays both.

Split the price into LBTT bands
Up to £145,000, £145,001 to £250,000, £250,001 to £325,000, £325,001 to £750,000, and anything above.
Tax each slice and add them up
0%, 2%, 5%, 10% and 12%. Each rate applies only to its own slice, never to the whole price.
Add 8% ADS on the whole price
If you'll own more than one dwelling after buying and the price is £40,000 or more, add 8% of the full purchase price, unless you're replacing your main home and the old one is sold by completion. That total is your bill.
Worked example
A £250,000 buy-to-let in Scotland, bought by someone who already owns their home, so ADS applies.
LBTT = (£145,000 × 0%) + (£105,000 × 2%) = £2,100
ADS = £250,000 × 8% = £20,000
Total = £2,100 + £20,000 = £22,100

How LBTT works on a buy-to-let
The 8% Additional Dwelling Supplement
If you'll own more than one dwelling after buying, you usually pay ADS on top of LBTT. It's 8% of the whole purchase price, not band by band, so a £250,000 flat carries £20,000 of ADS on its own. That includes buying a new main home before you've sold the old one.
Buying your first and only dwelling to let out? ADS doesn't usually apply. Companies generally pay ADS on residential purchases of £40,000 or more, even if they own no other dwelling, unless relief applies.
LBTT starts at £145,000
LBTT is charged in slices: nothing up to £145,000, then 2%, 5%, 10% and 12% on the parts of the price above each threshold.
If every buyer qualifies for first-time buyer relief, the nil-rate band rises to £175,000, worth up to £600.
