Stamp duty for first-time buyers: the threshold, the traps, the timing
Where the relief starts and stops, and why the completion date matters more than the day your offer is accepted.
Read the note
Relief is decided on the day you complete, not the day your offer is accepted. If the thresholds move between the two, the bill moves with them. They last moved in April 2025, and several buyers who exchanged in March paid more than they had budgeted.
Both buyers must qualify. If one of you has ever owned property anywhere in the world — including a share of an inherited flat — the relief is lost for the whole purchase, not half of it.
We calculate the duty in writing when we quote, and again on the morning of exchange. If the figure changes, you hear it from us before you hear it from the lender.
General information, not advice. The figures that apply to you depend on your circumstances and the date you complete.
