Portugal has spent more than a decade using the income-tax code as a talent-attraction tool, and in the last two years it tore up a big part of that toolkit and rebuilt it. If you run payroll for anyone employed in Portugal, this is not abstract policy. These regimes change the actual income tax withheld from real people's paychecks, sometimes to zero, and they are mutually exclusive, so the first question on a new hire is often "which regime, if any, is this person on," and an error there shows up directly in net pay. There are three regimes to know: NHR, which is closing to new entrants; IFICI, its narrower successor; and IRS Jovem, which was recently expanded.
Let me take them in order, because the order is how they replaced one another.
NHR: the regime that is closing
The Regime Não Habitual Residente, NHR, ran for years as Portugal's headline lure for foreign talent and returning nationals. For ten years it gave qualifying residents a flat 20 percent income-tax rate on certain high-value Portuguese-source work and broad exemptions on many kinds of foreign income. It did exactly what it was designed to do, and then it did a bit too much of it: it became politically tied to the housing-affordability backlash, and the government closed it to new entrants.
The important word for payroll is "new." NHR shut its doors to new applicants from 2024, with a transitional carve-out for people who were already in the pipeline. But anyone who was validly registered keeps their status for the remainder of their ten-year window. So NHR does not vanish from your payroll; it ages out, worker by worker, over the next several years. You will be running NHR withholdings for existing beneficiaries well into the 2030s while never enrolling anyone new. That "grandfathered but closed" state is exactly the kind of thing that gets mishandled when someone assumes a closed regime is a dead one.
IFICI: NHR's narrower successor
In NHR's place, Portugal created the Incentivo Fiscal à Investigação Científica e Inovação, IFICI, sometimes called "NHR 2.0." It was introduced by the 2024 state budget law under Article 58-A of the tax-benefits statute and given its operating rules by Portaria 352/2024. The headline is familiar: a flat 20 percent IRS rate on employment and self-employment income for ten consecutive years from becoming resident. The difference is who qualifies.
Where NHR was broad, IFICI is deliberately targeted at the talent Portugal actually wants to grow: scientific research and higher-education roles, technology and innovation, certified startup employees, R&D personnel, and specific highly qualified professions tied to companies making relevant investments. And it comes with real administrative gates. Eligibility runs through different registration bodies depending on the activity, the science foundation for researchers, the investment agency for certain roles, the startup agency for certified-startup staff, the tax authority for others, and registration has to happen by 15 January of the year after someone becomes resident. Miss the window and the benefit is at risk. One more line that matters: if someone previously held NHR, they cannot switch into IFICI. These regimes cannot be combined.
IRS Jovem: the one most of your payroll will actually feel
If NHR and IFICI are about attracting a relatively small population, IRS Jovem is the one that touches ordinary Portuguese payroll at scale, because it applies to young workers generally, and the 2025 state budget made it far more generous. The reform lifted the age ceiling to 35, dropped the old education requirement, and set a clear ten-year exemption schedule under Article 12-B of the personal income-tax code.
Here is the shape of it. In the first year of earning income, 100 percent of eligible pay is exempt from income tax. In years two through four, 75 percent is exempt. In years five through seven, 50 percent. In years eight through ten, 25 percent. From year eleven, full tax. The exemption is capped at 55 times the social-support index, which works out to about 29,542 euros of exempt income in 2026. Two details make this genuinely tricky to administer. First, the clock counts calendar years from the first year the person earned any Category A or B income, not years with the current employer, and it does not reset when they change jobs, so a new employer inherits a worker who might be in year one or year six. Second, IRS Jovem touches only income tax; social-security contributions are unaffected, so the employer still pays the full contribution on the whole salary.
Walk it through with a round number. Take a 26-year-old earning 2,000 euros a month who is in their first year of earning income. Their income-tax withholding that year is zero, because 100 percent is exempt, even though social security is deducted as normal. Fast-forward to their fifth year of income and only half their pay is exempt, so the tax withheld jumps. Same person, same salary, very different net pay, and the only variable is which year of the schedule they are in. Now imagine they join you in what is, unknown to you, their fifth year: if you start them at year one, you will under-withhold their income tax for months, and the correction lands on them.
Why this matters for anyone running Portuguese payroll
Put the three together and Portugal has turned its tax code into an active talent strategy with a lot of moving parts. A given worker might be on legacy NHR, on IFICI, on IRS Jovem, or on none of them, and the regimes are mutually exclusive, so you cannot apply more than one. For IRS Jovem in particular, the correct withholding depends on a per-person year count that follows the worker across employers and that no single payslip reveals on its own. The right year is invisible on the payslip until a year-end reconciliation or the worker's own tax return reveals a mismatch, at which point the question is whether the right regime and the right year were applied all along.
We track all of these tax regimes at Flux, so payroll stays correct. Flux records which regime applies to each worker, and for IRS Jovem the exemption year they are in, and applies the right income-tax treatment each month. That is what keeps a young worker from paying tax they do not owe, and an employer from facing a correction for one who was under-taxed.
