Adjustment of tax paid: repayments
If we are satisfied that too much tax or interest has been paid, the amount overpaid is repayable unless:
- the claim for repayment is made more than four years after the date of payment, or last payment, of the tax or interest - IHTA84/S241 (1), or
- there is a change in the view of law or practice (IHTM30451).
The four year limit does not apply where the charge to Inheritance Tax itself - (as distinct from the amount of tax charged) was based on an error of fact (for example, the assumption that a person has died when they are alive). For this purpose an alleged error in valuation is not an error of fact.
