Verdict
On the OECD tax wedge for a single average worker, Spain taxes labour more lightly than Portugal — a 2% smaller wedge as a share of total labour cost. But the wedge is a blunt comparison: it models one standard worker, ignores your actual income, family and deductions, and says nothing about what the taxes fund. The composition matters too — a country can have a similar wedge built from very different mixes of income tax versus employer contributions.

Frequently asked questions
Does Spain or Portugal have the lower tax wedge?
Spain has the lower tax wedge of the two: 40.2% of labour cost versus 42.3% for Portugal — a gap of about 2% of total labour cost for a single average worker. Both are measured against the OECD average of 34.9%. These are modelled averages, not personal tax.
Which keeps more take-home pay, Spain or Portugal?
Spain leaves the worker with more of their gross wage: a net personal average tax rate of 22.1% means they keep about 77.9% of gross, versus 71.5% in the other country. Note this "net rate" excludes employer social security, which still adds to the total wedge.
Why is the employer social-security difference between Spain and Portugal important?
Employer social security is part of the tax wedge but never appears on the payslip: it raises the cost of employing someone without raising gross pay. Spain charges 30.4% of labour cost in employer contributions versus 23.8% in Portugal. A high employer wedge means a worker on the same net pay costs the employer much more.
Should I compare Spain and Portugal on the tax wedge alone?
No. The tax wedge is a model of an average single worker at 100% of the average wage — it ignores your income level, brackets, family status, deductions and what those taxes buy (healthcare, pensions, schooling). Use it as a directional signal, read each country's full page, and consult a tax adviser before relocating. Not tax advice.
