Summary of "Small Businesses in South Africa: Who Outsources Tax Compliance Work and Why?"

Core Content

This paper investigates the outsourcing of tax compliance work by small and medium-sized businesses (SMMEs) in South Africa, analyzing the factors that influence this decision and the associated costs. The study is based on survey data collected from 998 SMMEs registered with the South African Revenue Service (SARS) and is part of a broader initiative by the World Bank to support tax reform and improve tax administration efficiency.

Main Findings

Outsourcing Patterns

• Outsourcing distribution:

  • 43% of SMMEs perform all tax compliance work in-house.
  • 11% outsource all tax compliance work.
  • 46% use a partial outsourcing approach, combining in-house and outsourced tasks.

• Inverted-U shape:

  • The smallest firms (under R300,000 turnover or well under US$50,000) tend not to outsource due to higher cost-burden and lower complexity.
  • Firms with turnover over R14 million also tend not to outsource, as they have sufficient in-house capacity.
  • Middle-sized firms are most likely to outsource, mainly due to the complexity of tax matters and the lack of in-house expertise.

• Legal form and outsourcing:

  • Sole proprietors and close corporations are more likely to outsource compared to PTY Ltd (private companies).
  • Partnerships and close corporations also show differences in outsourcing behavior.

• Turnover and outsourcing:

  • The outsourcing index decreases as turnover increases.
  • The Pearson correlation coefficient between turnover and outsourcing index is -0.210, significant at the 1% level.

• Employment and outsourcing:

  • The more employees a firm has, the less likely it is to outsource.
  • The Pearson correlation coefficient between number of employees and outsourcing index is -0.128, significant at the 1% level.

• E-filing and IT usage:

  • Firms using e-filing are less likely to outsource.
  • Firms that do not always use computers and specialized software are more likely to outsource.
  • Outsourcing and IT appear to be substitutes for SMMEs.

• Reasons for outsourcing:

  • 78% of firms that outsource do so because "tax is a specialist field."
  • Only 10% of firms that do not outsource cite cost as the main reason.
  • 80% of firms that do not outsource claim they have sufficient in-house expertise.

• Partial outsourcing:

  • Partial outsourcing is common across all tax activities.
  • There is no clear determinant of who partially outsources.
  • However, partial outsourcing is more frequent among firms experiencing post-filing issues such as disagreements with SARS assessments, inspections, and penalties.

Cost Analysis

• Costs of partial outsourcing:

  • Partial outsourcing firms face higher tax compliance costs due to duplication of effort.
  • These firms could potentially reduce costs by moving to full outsourcing.

• Modeling tax compliance costs:

  • A base hypothesis was tested: outsourcing tax compliance work to professionals saves money.
  • The study used an OLS regression model to analyze the cost of tax compliance, incorporating variables such as turnover, employment, and outsourcing indexes.

• Regression results:

  • In the Basic model, partial and full outsourcing indexes have positive coefficients, indicating they increase compliance costs.
  • In the Base model, these indexes remain significant.
  • The Restricted model was used to focus on firms that outsource at least some tasks.
  • The Polarized model analyzes firms that either fully outsource or do everything in-house.

• Variable significance:

  • The e-filing dummy variable is not significant.
  • The Western Cape Province dummy loses significance in the Restricted model.
  • In the Polarized model, variables such as VAT and legal form dummies become insignificant due to their impact on the full outsourcing dummy.

Policy Implications

• The study highlights the regressive nature of tax compliance costs, particularly for small firms.
• It suggests that encouraging full outsourcing could help reduce compliance costs and improve accuracy.
• The findings support the idea that IT tools such as e-filing can serve as a substitute for outsourcing.
• There is a need for policy reforms that improve tax administration and reduce the compliance burden on SMMEs.

Conclusion

The paper concludes that while outsourcing is common among middle-sized firms due to the complexity of tax matters, the costs are highest for those who partially outsource. Encouraging full outsourcing and promoting the use of IT tools could be beneficial in reducing the overall tax compliance burden. The study also emphasizes the importance of understanding the relationship between outsourcing and post-filing interactions with SARS to improve the tax environment for SMMEs.
