How it works
Revenue Scotland's residential bands have applied since 1 April 2021: 0% up to 145,000, 2% from 145,001 to 250,000, 5% to 325,000, 10% to 750,000 and 12% on anything above. The widget measures how much of the price lands in each band and adds the pieces, so 235,000 gives 1,800 and 875,000 gives 63,350 - both Revenue Scotland's own examples. First-time buyer relief stretches the nil band to 175,000, which saves at most 600 and has no price ceiling. The Additional Dwelling Supplement is different in kind: it is 8% of the entire price, charged for contracts from 5 December 2024 when you will own more than one dwelling and are not replacing your main residence, and it is not due on a price under 40,000. A 300,000 buy-to-let therefore carries 4,600 of LBTT plus 24,000 of ADS.
Calculation method
- LBTT = sum over bands of (portion of price inside the band x band rate)
- Bands from 1 April 2021: 0% to 145,000; 2% to 250,000; 5% to 325,000; 10% to 750,000; 12% above
- First-time buyer: the 0% band ends at 175,000 instead of 145,000 (saving up to 600)
- ADS = 8% x whole price when an additional dwelling and price >= 40,000 (from 5 December 2024)
- Total = LBTT + ADS; effective rate = total / price x 100
Worked examples
Home mover
Inputs: Price 235,000; home mover
Result: LBTT 1,800
Revenue Scotland example: 90,000 in the 2% band.
Upper bands
Inputs: Price 875,000; home mover
Result: LBTT 63,350
Revenue Scotland example: 2,100 + 3,750 + 42,500 + 15,000.
Buy-to-let with ADS
Inputs: Price 300,000; additional dwelling
Result: Total 28,600 (LBTT 4,600 + ADS 24,000)
LBTT 2,100 + 2,500; ADS 8% x 300,000.
First-time buyer
Inputs: Price 250,000; first-time buyer
Result: LBTT 1,500; relief saves 600
2% x (250,000 - 175,000) instead of 2% x 105,000 = 2,100.
An estimate for planning, not tax or legal advice. Your solicitor submits the LBTT return and confirms whether ADS or any relief applies.
Limitations
- Residential purchases by individuals only: non-residential, mixed property, leases and linked transactions are not covered.
- Whether ADS applies (ownership on the effective date, main-residence replacement, shares under 40,000) is taken from your choice, not tested.
- The 6% ADS transitional rate for contracts made on or before 4 December 2024 is mentioned but not computed.
Where publishers use it
- A Glasgow or Edinburgh letting agent's landlord page showing ADS on a typical tenement flat
- A Scottish solicitor-estate agent listing with the tax at the offers-over price
- A first-time buyer course in Scotland explaining why the relief is worth at most 600
- A holiday-let investment article for the Highlands comparing LBTT and ADS
- A relocation guide for people moving from England who expect SDLT rules
Questions
What is the LBTT on a 235,000 home?
1,800. The first 145,000 is at 0% and the remaining 90,000 sits in the 2% band. Revenue Scotland publishes this exact example.
How much does first-time buyer relief save in Scotland?
At most 600. It raises the nil band from 145,000 to 175,000, taking 30,000 out of the 2% band; any first-time buyer paying 175,000 or more saves the full 600, and there is no upper price limit.
How is the Additional Dwelling Supplement worked out?
It is 8% of the whole purchase price, not of the slices above a threshold, for contracts entered into from 5 December 2024. Earlier contracts completing later keep the 6% rate. It is not due when the price is under 40,000.
Can I get the ADS back?
Often, yes: if you sell your previous main home within 36 months of buying the new one, and the new home is your main residence, you can claim a repayment from Revenue Scotland. This widget shows the tax due on completion.
Do companies pay ADS?
Usually yes - Revenue Scotland applies ADS to most purchases of dwellings by companies and certain trusts even when it is their first property. Company purchases are not modelled here.
