People pay money to their leaders. 
People pay money to help their lands. This is called an income tax. 
Long ago, a leader in China tried this. He taxed people who caught fish. He also taxed people who picked fruit.
In England, a leader used tax for war. He wanted to buy tools and weapons. This helped his army.
Sometimes, people pay more if they earn more. This is a fair way to do it. It helps the country grow.
Many places use these rules today. It is a way to work together.
An income tax is a way to collect money. People or companies pay this money to their government. The amount depends on how much they earn. This is often called taxable income.
Many people pay different rates. Some systems use a progressive tax. This means the tax rate goes up as income goes up. For example, a person might pay nothing on their first bit of money. They pay a small part on the next bit. They pay more on even higher amounts.
This idea is not new. In the year 9 CE, a leader named Wang Mang tried it. He taxed people who caught fish or picked fruit. In England, William Pitt the Younger used tax in 1798. He needed money for a war. In the United States, the first income tax began in 1861. It helped pay for the American Civil War. Later, a new rule in 1913 made the tax part of the US law. Today, many countries use these rules to help run their lands.
An income tax is a way for governments to collect money from people and companies. This money is based on what those people or companies earn. This amount is often called taxable income.
How the tax is calculated can change depending on the rules. Many places use a progressive tax system. This means the tax rate goes up as a person earns more money. For instance, someone might pay 0% on their first $10,000. They might pay 1% on the next $10,000 they earn. Companies usually pay a corporate tax, which is often a flat rate.
Taxing income is a modern idea that needs a money economy to work. Long ago, people paid taxes on land, animals, or social status instead. In 9 CE, Emperor Wang Mang of the Xin dynasty created an early income tax. He taxed 10% of earnings from fishing, herding, and collecting fruit. People had to report their earnings to officials. If they did not, they could face hard labor or lose their property. This specific tax was ended in 22 CE because people were unhappy. 
In England, William Pitt the Younger introduced a progressive tax in 1798. He needed money to pay for weapons during the French Revolutionary War. His tax started at a low rate for incomes over £60. It went up to a maximum of 10% for incomes over £200. In the United States, the first personal income tax began on August 5, 1861. This helped pay for the American Civil War. The rate was 3% for all incomes over $800. 
The United States later passed the Sixteenth Amendment in 1913. This rule made the federal income tax legal under the Constitution. By the year 1918, the government collected over one billion dollars. By 1920, that amount grew to $5.4 billion. Tax rates in the US have changed a lot over time. During World War II, the highest tax rate was over 90%. Today, many countries like Canada, China, and Germany use similar systems to fund their governments.
An income tax is a specific type of tax imposed on individuals or entities. These entities are often called taxpayers. The tax is applied to the income or profits they earn. This amount is commonly referred to as taxable income.
Taxation methods can vary based on the characteristics of the taxpayer. For example, corporations usually pay a corporate tax. This is often applied as a flat rate. Individuals, however, are frequently subject to progressive tax rates. In a progressive system, the tax rate increases as the taxable income increases. For instance, a person might pay 0% on their first $10,000. They might then pay 1% on the next $10,000 they earn.
Calculating taxable income involves several specific steps and rules. Taxable income is generally the total income minus certain expenses. These are known as deductions. Deductions include income-producing expenses or business costs. Some jurisdictions also allow for the recovery of costs from business assets.
History shows that taxing income is a modern innovation. It requires a money economy and accurate accounting. For most of human history, taxes were based on different factors. People paid taxes on wealth, social position, or ownership of land and slaves. Some early practices included tithing, which was an offering of first fruits. In 9 CE, Emperor Wang Mang of the Xin dynasty established an early income tax. He taxed 10% of net earnings from activities like fishing and herding. However, this tax was abolished in 22 CE due to popular discontent. 
The modern era of income tax saw significant developments in Great Britain. In 1798, Prime Minister William Pitt the Younger introduced a progressive tax. He needed funds for the French Revolutionary War. This tax applied to incomes over £60 and reached a 10% maximum for incomes over £200. Although it was initially temporary, it became a fixture of the British system. Later, Sir Robert Peel reintroduced the tax in 1842 to address a budget deficit. This version was imposed on incomes above £150. 
The United States has a distinct history with federal income tax. The first personal income tax was imposed on August 5, 1861. This was to help fund the American Civil War. The rate was 3% on all incomes over $800. Later, in 1894, a peacetime income tax was passed. However, the Supreme Court ruled it unconstitutional. This obstacle was removed in 1913 with the Sixteenth Amendment. Following this, tax collections grew rapidly. In 1918, collections passed the billion-dollar mark for the first time. By 1920, they had risen to $5.4 billion.
Tax rates and rules continue to change based on national needs. In the United States, rates have fluctuated dramatically over time. During World War II, the highest tax bracket exceeded 90%. Today, many large nations follow similar principles. Countries like Canada, China, Germany, and Singapore all use various forms of income taxation. These systems help manage the complex needs of modern, organized societies.
