Stamp Duty Land Tax at Somerset prices
At the Somerset average of £282,498, a home mover pays £4,125 stamp duty. The price reaches the 5% band, which starts at £250,000, so every extra £10,000 adds £500.
First-time buyers are in the strongest position: the average first-time buyer price in Somerset, £232,749, is £67,251 under the £300,000 relief threshold, so they pay no stamp duty at that price, saving the £2,155 a home mover would pay.
By property type: the average flat, terrace and semi are under £300,000, where a first-time buyer pays nothing; the average detached house falls in the 5% relief band.
A second home or buy-to-let at the Somerset average pays £18,250, because the 5% surcharge applies to the whole £282,498.
Going £10,000 over the Somerset average adds £500 of stamp duty for a home mover.
