2694.This section deals with the basis of assessment. It identifies the amount of taxable social security income, which feeds into the computation of net taxable social security income in section 658. The section invokes sections 65, 68, 584 and 585 of ICTA.
2695.In ICTA the basis of assessment for a foreign social security benefit is given by the rules of Schedule D Case V. The social security income Part does not repeat those rules but cross-refers the reader to them. The rules are in section 65 of ICTA and include the remittance basis. Section 65 is modified by the rules for Irish income in section 68 of ICTA. Sections 584 and 585 of ICTA are also relevant. Section 584 gives relief for income taxed on an arising basis if that income cannot be remitted to the United Kingdom. Section 585 gives relief for income taxed on a remittance basis if the remittances are delayed.
