Goodwill amortisation

[Chanmuganathan]

Purchased goodwill amortisation has been disallowed in the tax computation for last 15 years. How do I correct this?
Thanks.

re tax - get current year right. Amend and refile online previous year. Submit an overpayment relief claim for the next 3 previous years. Don't think you can go back beyond 4 years.

re accounts - I'm assuming you have a 'material' error so a prior year adjustment will be needed.

re my previous reply - I'm assuming it's the right kind of GW that would allow a tax deduction for its amortisation. It may be 'old' goodwill hence the disallowance.
