Statutory Time Limits
Unless the legislation specifically provides for discretion, Stamp Duty time limits are mandatory. HMRC Stamp Taxes is unable to extend the statutory time limits.
Examples are the 2-year limit for claiming repayments (section 10 Stamp Duties Management Act 1891) and the 30-day period for giving notice of appeal against an assessment made under section 12 Stamp Act 1891 (section 13(2) SA1891).
