Double Taxation Relief: Germany: alterations to the amount of relief
Regulation 9 of SI2012/459
If the amount of the German bank levy paid changes, there will then be a corresponding change in the amount that can be claimed as relief in the UK. If this happens the responsible member is required to recalculate the amount of relief due and amend the claim.
The responsible member must also amend the claim if the actual amount of the German bank levy stays the same but a person receives a payment from the German authorities in respect of the levy.
Regulation 11 of SI2012/459
Where the amount of the German bank levy or the bank levy against which relief is claimed is altered then, provided a claim has already been made for double taxation relief, the claim or assessment may be revised for up to 6 years from when all material determinations have been made.
Regulation 12 of SI2012/459
Where the amount of relief becomes excessive the responsible member or relevant entity must inform HMRC within 12 months of the adjustment to the German bank levy.
