Income tax, consumption tax and capital gains

The main ways money is taxed: when you earn it, when you spend it, and when an asset grows.

The idea

Income tax is charged on what you earn — wages, business profits, sometimes interest and rent. It is often deducted automatically from pay; self-employed people usually have to set it aside and pay it themselves. Sales or consumption taxes are charged when you buy things, and are usually included in the price you see. They affect everyone who spends, whatever their income.

Capital gains tax, where it exists, is charged on the profit when you sell something that has grown in value, such as shares or property — not on the whole sale price, only the gain. Many countries treat some gains differently, for example on a main home or on investments held in special accounts.

Most people pay several kinds of tax without thinking about them as a total. Seeing them together shows how much of your money goes to tax, and where planning might help.

Why it matters

Knowing which taxes apply to you helps you budget accurately — especially if you are self-employed or selling assets — and avoid unpleasant surprises.

A real example

The situation
After a successful first year freelancing, Beatriz receives a large tax bill she had not planned for.
What happened
Because no tax had been deducted during the year, she had spent the money. She now moves a share of every payment into a separate tax account the day it arrives.
The takeaway
Income tax still applied; it just was not taken for her.

How people actually behave

Taxes that are deducted automatically or built into prices feel invisible, while taxes paid as one bill feel large and painful — even when the amount is the same.

Common mistakes

  • Forgetting to set aside tax on income that has none deducted.
  • Assuming the whole sale price of an asset is taxed, rather than the gain.
  • Ignoring consumption taxes when comparing prices across places.

Questions to think about

  • Which taxes do you pay directly, and which are hidden in prices?
  • Do you have any income where tax is not deducted automatically?

Try it: Your tax picture

  1. List the kinds of tax you paid last year: on income, on spending, on anything you sold.
  2. Estimate each one.
  3. Note any income where you need to set tax aside yourself.
