How many IRS brackets does Portugal have?

Mainland Portugal uses nine progressive IRS brackets, from about 13 percent on the lowest band up to 48 percent on income above roughly EUR 81,000. Each rate applies only to the slice of income within its band.

What is the family quotient (quociente familiar)?

Married couples filing jointly can opt to split their combined income: total income is divided by two, the tax on that half is computed, and the result is doubled. Because the brackets are progressive, this usually lowers the combined bill. This tool models the simple two-person split.

What is the solidarity surcharge?

On top of regular IRS, Portugal levies an additional solidarity rate of 2.5 percent on taxable income between EUR 80,000 and EUR 250,000, and 5 percent on the portion above EUR 250,000. The tool adds this automatically for high incomes.

Does this include the personal deduction or tax credits?

No. This estimator applies the bracket schedule and solidarity surcharge to your taxable income. Personal collection deductions (health, education, dependants) reduce the final tax afterwards and depend on your receipts, so confirm with the Portal das Finanças.

Is this for mainland Portugal or the islands?

This uses mainland (continente) brackets. The Azores and Madeira apply their own reduced IRS rates, so residents there should use the regional schedules for an accurate figure.

Portugal IRS Income Tax Calculator

Portugal taxes personal income through the IRS (Imposto sobre o Rendimento das Pessoas Singulares), a steeply progressive system with nine brackets. Married couples can split income via the family quotient, and high earners pay an extra solidarity surcharge. This calculator applies the mainland schedule and shows the IRS due, your average rate, and net.

How it works

IRS is marginal — each rate applies only to the income within its band. The mainland brackets used here are:

Taxable income (EUR)	Rate
0 to 7,703	13.0%
7,703 to 11,623	16.5%
11,623 to 16,472	22.0%
16,472 to 21,321	25.0%
21,321 to 27,146	32.0%
27,146 to 39,791	35.5%
39,791 to 51,997	43.5%
51,997 to 81,199	45.0%
above 81,199	48.0%

For married joint filing, the tool divides total income by two, computes the bracket tax on that half, and doubles it (the family quotient). It then adds the solidarity surcharge: 2.5% on income from 80,000 to 250,000, and 5% above 250,000.

Example

For single taxable income of EUR 30,000, the tool taxes each band in turn (13% on the first 7,703, 16.5% on the next slice, and so on up to 35.5% on the top portion), producing total IRS of roughly EUR 7,500 — an average rate near 25%.

Notes

This applies the schedule and surcharge to taxable income. Personal collection deductions reduce the final figure, so treat this as an estimate and confirm via the Portal das Finanças.
