Inland Revenue Authority of Singapore (IRAS) reports how many taxable companies fall into each chargeable income range, together with aggregate chargeable income and net tax assessed from Year of Assessment (YA) 2004 through YA2022. Income is assessed on a preceding-year basis, and figures are stated as at 31 March following each YA. Two CSV datasets split earlier and later YA ranges for analysts studying corporate tax incidence and firm-size distributions. This IRAS collection supports open-data research on Singapore company taxation by income group.

Inland Revenue Authority of Singapore CSV of taxable companies by chargeable income group for Years of Assessment 2008 through 2024, with company counts, chargeable income, and net tax assessed.

This Inland Revenue Authority of Singapore (IRAS) dataset summarises taxable companies for Years of Assessment 2004 to 2007, grouped by assessed income band. For each year of assessment and income group it reports the number of companies, their assessable income and the net tax assessed, giving a picture of how corporate tax liability was distributed across smaller, mid-sized and larger earners. IRAS cautions that net tax assessed differs from tax actually collected, since GIRO instalments and reviews of prior-year assessments shift collections across financial years. Analysts use the series for historical studies of Singapore's corporate tax base, effective tax burden and the concentration of income among companies.
