931 Making of assessments and application of income tax assessment provisions

(1) Capital gains tax assessments are to be made by inspectors or other officers appointed by Revenue.

(2) Subject to any necessary modifications, the rules relating to the assessment of income tax apply for capital gains tax assessment in the same way as they apply in relation to income tax chargeable under Schedule D.

(3) Without prejudice to the general application of those rules, certain income tax assessment provisions are specifically applied, subject to any necessary modifications, for the purposes of capital gains tax. The provisions so applied are those governing —

• the making of assessments (section 918),
• the granting of allowances and reliefs (section 920),
• assessment in absence of return (section 922),
• additional assessments (see section 924),
• transmission to Collector-General of particulars of sums to be collected (section 928),
• double assessment (section 929), and

In the case of persons within the Self Assessment system the provisions of Part 41, in particular sections 954, 955 and 956 should also be consulted. However, as respects the tax year 2013 (and subsequent years) and accounting periods of companies that start on or after 1 January 2013, the provisions of Part 41A (as inserted by Finance Act 2012) apply.

By virtue of section 871 any assessment to capital gains tax may be combined with one relating to income tax or, as the case may be, corporation tax.
