Key Insight

This dataset reveals a significant growth in the number of taxable companies across most economic sectors in Singapore between 2004 and 2013. The Financial sector consistently shows the highest assessable and chargeable income, highlighting its dominant role in the Singaporean economy. The Wholesale & Retail Trade sector displays the largest number of companies throughout the period. Note that data on assessable, chargeable and net tax assessed is incomplete, limiting the scope of the analysis.

Small Interesting Points of Note

There is a noticeable increase in the number of companies in the Construction sector, potentially reflecting growth in infrastructure development. Data for 2004-2007 only includes assessable income while data from 2008-2013 only has chargeable income. Further, there are significant gaps in 'net_tax_assessed' data which limits our understanding of overall tax revenue.

Methodology

• Data was extracted and cleaned.
• The number of companies was aggregated for each sector and year.
• Trends in the number of companies were observed across years and sectors.
• Assessable income, chargeable income and net tax assessed values (where available) were reviewed to understand financial trends.
• Missing values were noted; these present a significant limitation in drawing robust conclusions.
