Money & State

The pension system assumes that younger workers will pay today's pensions. AI assumes we need fewer younger workers.

The demographics are hard enough on their own. Now a second calculation is being added, and it is missing from the public debate.

The Austrian pension system is pay-as-you-go. The contributions coming in today go straight back out today as pensions. There is no money sitting in an account waiting for the day you retire. There is a contract between the generations: today’s working generation pays for today’s pensioners. Their children pay for them later. So the whole system rests on a single assumption. That enough people will keep paying in.

Demographically, that assumption has been cracked for a while. The large birth cohorts of the 1960s are retiring now, the generations after them are much smaller, and fewer children are being born than at any point since records began. Today each person over 65 is matched by a good three people of working age; by 2040 it will be around two. Everyone who is meant to be working then has already been born. That number cannot be changed anymore. The only open question is who joins from outside.

The consequences have long been showing up in the federal budget. Every year the government closes the gap between contributions and payouts, and that subsidy keeps growing. Add up all pension-related spending and nearly a quarter of every tax euro flows into pensions. The trend is upward, and the baby-boomer retirement wave has not even fully arrived yet.

That is the calculation without AI. With AI, a second effect comes on top. The pay-as-you-go system draws its contributions almost entirely from payslips. As knowledge work is increasingly handled by AI agents, some of those payslips disappear. Even if the salaries that remain go up: positions that have been cut pay in nothing. The output stays in the country, it even rises. But it is no longer paid out as wages. And so it no longer pays into the pension system.

The effect also works on a delay. Anyone not hired now is missing from the system twice: at once as a contribution, and decades later as a career that never started. The first signals are already there at the entry into working life, in Austria as in the US.

Political debate in Austria has circled the retirement age and the adjustment formula for years. Both are legitimate levers, both aim at the demographic part of the calculation. Neither reaches the second part, the one taking shape right now. If output is increasingly produced by software, you cannot fix a pension system by making people work longer when they can barely sell their work anymore. Broadening the contribution base beyond payslips, taxing output rather than the wage bill, barely features in the Austrian debate at all. The demographics have been visible coming for decades. The second effect almost nobody sees yet.

In depth

What a payslip pays into the system

Of your gross salary, 22.8 percent goes into the pay-as-you-go system as a pension insurance contribution: 12.55 percent paid by the employer, 10.25 percent by the employee. On a gross annual salary of 60,000 euros, that comes to roughly 13,700 euros a year per position.

With that money, the statutory pension insurance funds around 2.56 million pensions currently being paid out. As of 1 July 2024 these went to about 2.3 million people (Statistik Austria). More pensions than recipients sounds odd at first, but the reason is plain: around 282,000 people draw two or more pensions at once, usually their own old-age or disability pension plus a survivor's pension.

On the other side are the people paying in. Around 3.68 million compulsorily insured workers, people making ongoing contributions through their jobs, carried the system in 2024 (annual average, Pensionsversicherungsanstalt). That is not the rule of thumb from the main text: there, each person over 65 is matched by about three people of working age, but that is pure demographics. Not everyone of working age pays in, and not every pension goes to someone over 65. The real number of contributors per pension being paid out is well below three.

Demographics and the federal subsidy in numbers

The fertility rate stood at 1.31 children per woman in 2024, the lowest figure ever recorded (Statistik Austria). The share of people over 65 rises, according to Statistik Austria's main projection, from around 20 percent today to 26.2 percent in 2040.

Workers' contributions are not enough to fund the pensions being paid out. In 2024 the federal government transferred around 15.8 billion euros to the statutory pension insurance (Arbeiterkammer analysis). Including civil-servant pensions, equalisation supplements and other pension-related federal funds, total budget spending on pensions came to around 25.7 billion euros in 2023. That is around 23.5 percent of the federal budget and about 5.4 percent of GDP (figures from the federal financial statement).

The Alterssicherungskommission expects that the federal contribution to the statutory pension insurance alone will exceed four percent of GDP for the first time by 2030, around 20 billion euros measured against today's economic output. EcoAustria expects roughly 19 billion euros in additional cumulative spending by 2030, from the baby-boomer retirement wave alone.

Where the second effect kicks in

A law firm that hires two juniors instead of ten and hands the rest of the work to software stops paying pension contributions on eight positions. The firm's output stays the same, the contribution base shrinks.

You can already see it at the point of entry into working life. The number of first-year apprentices in industry fell 14 percent in 2025 (WKO). In the US, employment of 22- to 25-year-olds dropped by around 16 percent since the end of 2022, specifically in jobs whose routine work AI can take over (Stanford 2025). Both are early indicators with several possible drivers, the business cycle plays a part too, but the pattern fits the mechanics described here.
