I am severely disabled and need expensive medication, some of which I have to pay for myself. Are these self-paid costs covered by the disability allowance?

No. The lump-sum allowance for the disabled only covers current and typical expenses for assistance with the usual and regularly recurring activities of daily living, for care and for increased laundry needs. The expenses covered by the lump sum "for everyday activities" are only those expenses which also arise for non-disabled persons, but which are somewhat higher in the case of disabled persons and which cannot be deferred. All other disability-related expenses - e.g. surgery costs as well as curative treatments, cures, medical costs and doctors' fees - can also be taken into account as an extraordinary burden in accordance with § 33 of the Income Tax Act.
