Tax evasion is a big problem that hurts governments all over the world. It causes them to lose a lot of money and makes things unfair.
I’m curious about why people hide part of their income even though they might get caught and punished. This question has been interesting to economists and lawmakers for a long time.

In 1972, Allingham and Sandmo started a big conversation with their work. They used expected utility theory to understand why people might not pay all their taxes. Their paper in the Journal of Public Economics helped shape how we think about public economics today.

- It’s key for lawmakers to understand why people might not pay taxes to fix the problem.
The Economic Significance of Tax Evasion
Understanding tax evasion’s impact is key to good tax policies. It’s a big problem worldwide, causing huge losses for governments. It also makes social inequality worse.

Global Impact of Tax Evasion
Tax evasion hurts the global economy a lot. It makes governments lose a lot of money. This affects how much money they can spend on public things.
Revenue Losses for Governments
Governments lose a lot of money because of tax evasion. This means they can’t spend as much on important things. It slows down economic growth.
Social Inequality Consequences
Tax evasion makes social inequality worse. When some people don’t pay taxes, others have to pay more. This makes things unfair and increases differences between people.
In short, tax evasion has big effects on both government money and fairness. We need good tax rules to fix these problems and make things fairer.
Historical Context of Tax Evasion Research
The study of tax evasion has a long history. It goes back before the work of Allingham and Sandmo in 1972. Knowing this history helps us see how tax evasion research has grown.
Pre-1972 Approaches to Tax Evasion
Before 1972, people mostly looked at tax evasion through descriptive and non-theoretical studies. These studies gave us facts about tax evasion but didn’t have a clear way to analyze them.
Descriptive and Non-Theoretical Studies
Most studies were descriptive, telling us about tax evasion. They showed us how common it was. But, they didn’t have a theory to explain it all.
Limitations of Early Research
These early studies had big problems. They couldn’t explain why people evaded taxes or how policies might change things. This showed we needed a better way to study tax evasion.

Without a good theory, making tax laws better was hard. Allingham and Sandmo’s work in 1972 changed this. They started a new way to think about tax compliance.
“Income Tax Evasion: A Theoretical Analysis” (1972) by Michael G. Allingham and Sandmo
In 1972, Michael G. Allingham and Agnar Sandmo changed how we see income tax evasion. Their work, “Income Tax Evasion: A Theoretical Analysis,” was a big step forward. It helped us understand why people might not pay their taxes.
Background of the Authors
Michael G. Allingham is a famous economist. He works a lot on public economics. Agnar Sandmo is also well-known, focusing on public finance and tax policy. Together, they made a big impact with their 1972 paper.
Academic Contributions
Allingham and Sandmo’s work has made a big difference in public economics. Their ideas on tax evasion have been very important. The Journal of Public Economics says their paper was a key moment in tax evasion theory.
“The Allingham-Sandmo model has become a cornerstone in the literature on tax evasion, providing insights into the factors that influence taxpayer compliance.”
Research Motivation
Allingham and Sandmo wanted to know why people don’t always pay their taxes. They created a model to explain this. They looked at how things like audits and penalties affect tax payments.
| Author | Contribution |
|---|---|
| Michael G. Allingham | Developed the theoretical framework for tax evasion analysis |
| Agnar Sandmo | Provided insights into public finance and tax policy |
Their research has changed how we think about tax evasion. It helps make policies that encourage people to pay their taxes. Allingham and Sandmo’s theoretical analysis is still very important today.

Their work is also important because it was published in the Journal of Public Economics. This shows how influential their research is. It helps us talk about tax compliance and evasion in a better way.
The Allingham-Sandmo Theoretical Framework
The Allingham-Sandmo model changed how we see tax evasion. It created a framework that looks at how people act when they’re not sure. This has helped a lot in talking about tax rules and breaking them.
Core Assumptions of the Model
The Allingham-Sandmo model is based on key ideas. It says rational taxpayer behavior is at the center. This means people make smart choices based on what they think will happen.
Rational Taxpayer Behavior
The idea of rational taxpayer behavior is key. It says people think carefully about tax evasion. They look at the good and bad sides, like getting caught and fines.
Allingham and Sandmo said, “The taxpayer is assumed to maximize expected utility,” (Income Tax Evasion: A Theoretical Analysis, 1972). This means they make choices based on what they think will happen. Things like how scared they are and how much money they make play a part.

The decision to declare income is very important in the Allingham-Sandmo model. It looks at how much income people choose to report. They think about the good of not paying taxes and the bad of getting caught.
The model shows how complex this decision is. It involves how scared people are and the rules around taxes. Experts say, “Deciding to evade taxes is not easy. Many things, like the chance of getting caught and how bad the penalties are, matter.”
Understanding these ideas helps us see how taxes work. The Allingham-Sandmo model gives us important insights into tax rules and breaking them.
Mathematical Formulation of the Model
The Allingham-Sandmo model gives us a way to think about tax evasion. It helps us see how people decide to follow tax laws.
Key Variables and Parameters
The model looks at several important things. These are income, tax rate, penalty rate, and how likely it is to get caught.
Income, Tax Rate, and Penalty Rate
The model says income, tax rate, and penalty rate matter a lot. They decide if someone will follow the tax laws. For example, a high tax rate might make people want to hide money. But a big penalty might make them think twice.
Probability of Detection
How likely it is to get caught is very important. If there’s a good chance of being caught, people might pay their taxes more often.

| Variable/Parameter | Description | Effect on Tax Compliance |
|---|---|---|
| Income | Taxpayer’s total income | Increased income may lead to increased tax evasion |
| Tax Rate | Rate at which income is taxed | Higher tax rates may encourage tax evasion |
| Penalty Rate | Rate of penalty on evaded taxes | Higher penalty rates deter tax evasion |
| Probability of Detection | Likelihood of detecting tax evasion | Higher detection probability increases compliance |
In conclusion, the Allingham-Sandmo model is a detailed way to study tax evasion. Knowing about these key parts helps make better tax rules. This can help people follow the tax laws more.
Policy Implications of the Allingham-Sandmo Model
The Allingham-Sandmo model shows how to stop tax evasion. It helps governments make better plans to get people to follow tax rules.
Deterrence Factors: Audit Probability and Penalty Rates
Deterrence is key in tax rules. The model talks about two important things: audit chance and penalty rates. Audit probability is how likely a check will happen. Penalty rates are the fines for not paying taxes.
“The threat of audit and the severity of penalties are critical in deterring tax evasion,” as emphasized by the model. A higher chance of audit and harsher penalties make people less likely to cheat on taxes.
Effectiveness of Enforcement Mechanisms
How well tax rules are enforced matters a lot. It’s not just about audits, but also how well tax authorities catch and punish cheaters. Efficient enforcement mechanisms make people think they might get caught.

Tax authorities need to think about costs when enforcing rules. More audits and penalties can stop cheating, but it costs money and might upset taxpayers. Finding a good balance is key.
In short, the Allingham-Sandmo model gives us important lessons on stopping tax evasion. By knowing what works and how to enforce rules, governments can get more taxes and make people follow the rules better.
Critiques and Extensions of the Original Model
The Allingham-Sandmo model has been very influential. But, it has faced many criticisms and updates. It has greatly shaped how we think about tax compliance.
Theoretical Limitations
The Allingham-Sandmo model is foundational but has its limits. It has simplifying assumptions and leaves out some behaviors.
Simplifying Assumptions
The model assumes taxpayers are risk-averse and audit chances are set. Critics say these might not match real life.
Omitted Behavioral Factors
The model also leaves out social norms and the moral costs of cheating. Studies show adding these can change the model’s results a lot.

A study compared different tax models. It showed how important behavior is:
| Model | Key Features | Impact on Compliance |
|---|---|---|
| Allingham-Sandmo | Risk aversion, audit probability | Baseline compliance rate |
| Extended Model | Includes social norms, moral costs | Increased compliance rate |
“Adding behavior to tax models is a big step. It helps us understand taxpayers better.”
— Journal of Economic Psychology
The Allingham-Sandmo model’s updates show how tax theory is growing. It now uses insights from behavioral economics to get a clearer picture of taxpayer actions.
Relevance to Modern Tax Compliance Theory
Modern tax compliance theory has changed a lot since the Allingham-Sandmo model. It now includes insights from behavioral economics. This change helps us understand how taxpayers act today.
Behavioral Economics Perspectives
Behavioral economics has made tax theory better. It shows that money isn’t the only thing that matters. Psychological and social factors also play a big role.
Non-Monetary Motivations
Things like tax morale and wanting to follow rules matter a lot. Studies show people are more likely to pay taxes if they think it’s fair. They also want to do their part for society.
Psychological Factors in Compliance
How likely someone thinks they’ll get caught and the shame of cheating also matter. Knowing this helps make better rules for taxes.

| Factor | Influence on Compliance | Policy Implication |
|---|---|---|
| Tax Morale | Positive | Enhance public trust in tax authorities |
| Perceived Fairness | Positive | Ensure equitable tax burden distribution |
| Probability of Detection | Positive | Increase audit frequency and visibility |
In conclusion, the Allingham-Sandmo model is still important today. It laid the groundwork for modern tax theory. By understanding what motivates people, we can make taxes better.
Conclusion: The Lasting Impact of Allingham and Sandmo’s Work
Allingham and Sandmo’s 1972 study changed public economics a lot. Their work is still important today. It helps us understand how to make tax rules better.
Their ideas help us see why people might not pay taxes. They looked at how likely audits are and how penalties work. This helps us make tax rules that work better.
Today, their ideas are still used in tax rules. Tax systems keep changing, but their ideas help keep tax evasion low. This is very important.
In short, Allingham and Sandmo’s work is very important. It helps us make tax rules better. Their ideas will keep helping us for a long time.
