### Overview
- Presumptive taxation is used in many countries to tax hard-to-tax activities and reduce evasion.
- The paper assesses whether presumptive taxation can raise revenue and whether it undermines macroeconomic stability by lacking the automatic stabilizer properties of progressive income taxation.
- Two simple models are developed; one model’s relevance to presumptive excise taxation in Pakistan is examined.

### Research questions
- Could revenue be increased by adopting presumptive tax methods?
- Would presumptive income taxation contribute to macroeconomic instability because it lacks the automatic stabilizer property of standard progressive income taxation?

### Models and key findings
- Two simple theoretical models suggest:
  - There is scope for increasing revenue under presumptive taxation.
  - Revenue increases under presumptive taxation do not necessarily undermine economic stability.
- The analysis considers the behavior of a risk-averse taxpayer, tax liability, aggregate tax liability, distortionary taxation, and the role of utility functions in determining taxpayer responses.

### Relevance to Pakistan
- The first model is examined for its applicability to presumptive excise taxation in Pakistan.
- The paper discusses policy-relevant implications for countries using presumptive excise approaches to tax hard-to-tax activities.

### Policy implications and considerations
- Presumptive taxation can be a tool to improve net revenue collection from activities subject to evasion or difficult to administer under standard income taxation.
- Adoption of presumptive taxation methods should weigh potential efficiency gains against distributional and stabilization considerations associated with deviating from progressive income taxation.
- Implementing presumptive taxation for global income is presented as a case worth considering in light of possible efficiency gains.
