Typical effective tax rates at different incomes

Key rules

• Effective rate: It is your total tax divided by your total income, and it is always below your marginal rate.
• Marginal rate: It applies only to the next euro you earn, not to your whole income.
• Budgeting: Use a published effective-rate range for your income level, not the top rate.
• Variation: Your real rate depends on the year, your family situation, your income type and your region.

Published effective rates vary by year, family situation, income type and region, so confirm current figures in the tax agency's statistics and simulators before budgeting.

Your effective rate is always lower than the top rate

Your effective rate is the share of your total income that goes to tax. It is always lower than the top rate you hear quoted. Don't budget with the top rate.

The top rate, called the marginal rate, applies only to the next euro you earn. Spanish income tax is progressive, so each slice of income is taxed at its own rate. Only the part that falls inside a higher slice pays the higher rate.

A worked example

These rates are made up to show the logic. They are not Spanish rates.

• The first 10,000 is taxed at 20%. That is 2,000.
• The next 10,000 is taxed at 30%. That is 3,000.
• On 20,000 of income, you pay 5,000 in total.
• Your effective rate is 25%. Your marginal rate is 30%.

The gap between the two is the point. The more of your income sits in the lower slices, the further your effective rate falls below the marginal rate.

How effective rates behave as income grows

Effective rates rise steadily with income. They start low for average earners and become much higher for the highest incomes. Even at the top, they stay below the top marginal rate.

The exact rate at a given income depends on:

• the tax year
• your family situation
• the type of income (salary, savings, self-employment)
• the region you live in, because regions set part of the scale

So any single table of rates is only a guide. Use it to set a budgeting range, not an exact figure.

Where to find real figures

The tax agency publishes statistics on what taxpayers at different income levels actually pay. Studies from public research bodies, such as the Instituto de Estudios Fiscales and FEDEA, also give effective rates by income. These are the best source for a realistic range. The resources below list the official simulators and tables.

For a figure that fits your case, run your own numbers through the official simulator. Then check your region's current scale, since regional rates change.

Official simulators and tables to check current rates

Where to check current rates and estimates

• The AEAT, Spain's tax agency (online office): Use the Renta WEB service to prepare your annual return and see a draft and result before you submit it. Look under the Renta section.

• The AEAT, Spain's tax agency (online office): Use the withholding calculator under the Calculators and Help section to see how much tax your employer should hold back from your pay.

• The AEAT, Spain's tax agency (Renta campaign pages): Read the practical Renta manual for the tax year you file. It sets out the state and regional scales, minimums and deductions region by region.

• The AEAT, Spain's tax agency (published statistics): Look at its income tax statistics to see the effective rates that taxpayers at different income levels actually pay.

• Your region's official gazette: Check the regional law for your region if you want its own scale, minimums and deductions. Each region can change these.

Frequently asked questions

What is the difference between my effective rate and my marginal rate?

Your effective rate is your total tax divided by your total income, while your marginal rate is the rate on your next euro of income. Only the slice of income inside each bracket is taxed at that bracket's rate. For example, if the first 10,000 is taxed at 20% and the next 10,000 at 30%, tax on 20,000 is 5,000. That is an effective rate of 25% against a marginal rate of 30%.

Where can I find real effective rates for different incomes?

You can find real effective rates in the statistics the AEAT, Spain's tax agency, publishes on income tax filers. Studies from research bodies also publish them. The exact rate at a given income depends on the year, your family situation, the type of income and your region.

Can I use the top rate to budget my tax?

No, the top rate overstates your bill, because your effective rate is always below your top marginal rate. Effective rates rise with income, from low for average earners to much higher for the highest incomes. Budget with an effective rate from published statistics for your income level.
