What taxes are
A tax is money people pay to the government so it can run public services. A public service is something the government provides for everyone, like firefighters, schools or roads.

The key words
| Word | What it means |
|---|---|
| Tax | Money paid to the government to run public services |
| Income tax | A tax on the money you earn from work |
| Sales tax | Extra money added to the price when you buy something |
| VAT | Value Added Tax, a tax included in the price of goods and services in many countries |
| Tax return | A form you fill in each year to show how much tax you owe |
| Taxpayer | Any person or business that pays taxes |
| Public service | Something provided for everyone, like schools or fire services |
Common types of tax
Rules and rates differ from country to country, so always check the official tax authority where you live. In general, you will meet these:
| Tax | How you meet it |
|---|---|
| Income tax | Taken from what you earn at work |
| Sales tax or VAT | Included in or added to the price in shops |
| Other taxes | Taxes on property, companies or specific goods, depending on the country |
Where the money goes
Taxes pay for things most of us use without thinking about the bill: schools, hospitals, roads, public transport, police and fire services, and support for people who need help.
That is why it helps to see tax as a shared fund. Everyone adds a little, and everyone can use the services.
Taxes in your own life
- Look at your first payslip: it shows tax taken before you are paid.
- Check receipts and prices to see if VAT or sales tax is included.
- Keep your documents in one place so a tax return is easier.
- Use official sources when you are unsure. Mondosol cannot give tax advice.
