Can You Pay Stamp Duty with a Credit Card?

In short: Stamp Duty Land Tax must be paid to HMRC within 14 days of completion. Normally your solicitor files the return and pays the tax from funds you send them before completion. HMRC doesn't accept payments by personal credit card, so you'll need to fund it by bank transfer. If you're short of funds, speak to your mortgage broker before you commit to buy, as adding stamp duty to borrowing can change your loan-to-value.
