The tension between EU law, the rights individuals derive therefrom and domestic tax regimes has been a recurring theme of tax litigation in the last 15 years. In particular, the limitation period for claims to recover overpaid output VAT provided by VATA 1994 s 80(4) has endured a prolonged assault by claimants pleading a range of positions, from offence to accrued legal rights in the absence of transitional periods to fundamental attacks on the validity of the statutory mechanism. Some have yielded results, while others have faltered. However, the latest decision of the Supreme Court in this battleground has come down firmly on the side of HMRC and the exhaustive nature of the domestic statutory repayment scheme for overpaid VAT.
