Key Insight

Analysis of tax and penalty data from 2002 to 2023 reveals a fluctuating trend in the number of cases and the amount of tax and penalties arising from audits across different tax types (GST, Corporate Income Tax, and Individual Income Tax). While the number of cases shows a general downward trend from 2002-2023, the tax and penalty amounts have increased significantly since 2013, particularly for Corporate Income Tax, indicating greater enforcement or higher non-compliance in this area.  GST cases and amounts have seen some fluctuation, but Corporate Income Tax has demonstrated substantial year-on-year variations.  Further investigation is needed to understand the drivers behind these fluctuations.

Small Interesting Points of Note

The tax and penalty amounts are significantly higher for GST and Corporate Income Tax than Individual Income Tax.  The split of Income Tax into Corporate and Individual Income Tax occurred in 2009. This shows a need for further disaggregation to provide a fuller picture, as earlier years lack the same level of specificity.

Methodology

• Data was extracted from the provided JSON response and cleaned.  Numerical values were converted to appropriate numeric types for calculations.
• Trends were assessed by examining the year-over-year changes in the number of cases and tax/penalty amounts for each tax type.
• Statistical summaries (min, max, average) were calculated for number of cases and tax/penalty amounts for each tax type across the entire period. Note:  These are not included in the Key Insight as these values provide little context without further examination.
• Anomalies were identified by visual inspection of the trends and data values, but no formal statistical anomaly detection was performed.
• The overall increase in tax and penalties since 2013 is noted and warrants further exploration.
