Finland may replace part of its social security system with a universal basic wage as it looks to rein in state spending.
A government-commissioned working group is proposing a tax-free monthly wage of 550 euros.
A two-year trial starting next year will involve up to 10,000 people.
The sum is roughly equal to Finland's unemployment allowance.
Wage-earning participants in the project would pay the money back via increased income tax.
Switzerland is to hold a referendum on whether to introduce basic income for all adults, and the Netherlands and France are considering similar moves.
