Frequently Asked Questions & Detailed Tax Guide

What is First-Time Buyer Stamp Duty Relief?

First-time buyers in England and Northern Ireland benefit from a dedicated Stamp Duty Land Tax (SDLT) relief designed to reduce the upfront cost of homeownership. Under the 2026/27 tax year rules, eligible first-time buyers pay **0% Stamp Duty on properties purchased up to £425,000**. If the purchase price is between £425,001 and £625,000, you pay a discounted rate of 5% on the portion exceeding £425,000. If the purchase price exceeds £625,000, you lose the relief entirely and must pay standard residential Stamp Duty rates on the entire purchase price.

Step-by-Step Mathematical Calculation: First-Time Buyer Relief

Let’s calculate the Stamp Duty due for a first-time buyer purchasing a flat in London for £500,000:

  • 1. Check Eligibility: The purchase price (£500,000) is below the £625,000 maximum threshold, so first-time buyer relief applies.
  • 2. Calculate Nil-Rate Portion: The first £425,000 is completely tax-free (0% SDLT). Tax paid: £0.
  • 3. Calculate Taxable Portion: The amount between £425,001 and £500,000 is £75,000, taxed at 5%.
    – Tax due: £75,000 * 5% = **£3,750**.
  • 4. Total Stamp Duty Payable: **£3,750**.
  • 5. Savings: A standard buyer purchasing the same home would pay £12,500, meaning first-time buyer relief saves £8,750 on this transaction.

Tax Expert Pro-Tips: Joint Purchases and Ownership Status

David Vance, CTA FCA, recommends: “To qualify for first-time buyer relief, *all* buyers in a joint transaction must be first-time buyers. If you are buying a home with a spouse or partner who has ever owned or inherited residential property anywhere in the world, the relief is lost. If this is the case, it may be tax-efficient to purchase the property in the sole name of the first-time buyer, provided they can satisfy the lender’s mortgage affordability requirements on their single income.”
