When is the best time to open a PER so that it can truly fulfill its purpose?

A retirement savings plan is neither a miracle product nor a simple year-end tax-saving tool. Its effectiveness depends above all on when it is incorporated into a broader wealth management strategy. If introduced too early, it may lack relevance. If introduced too late, it can sometimes become merely a tax tool, disconnected from a genuine long-term savings plan. Somewhere in between lies a sweet spot where the PER truly reveals its value.
 

Introduced in 2019 in the wake of the Pacte Act, the Retirement Savings Plan (PER) has profoundly reshaped the landscape of long-term savings in France. It is designed to consolidate, under a single umbrella, approaches that were previously scattered across individual products and workplace plans. In its individual form, the PER is available to any adult, regardless of status, but its actual benefits vary significantly depending on age, income level, and career path.
 

In reality, the most favorable period often falls in the middle of one’s working life, between the ages of 30 and 50. At this stage, one’s career is generally stable, income is more predictable, and the tax burden is often higher. It is precisely this combination that makes the PER a relevant option. Voluntary contributions allow you to reduce your income tax today, while giving your capital time to grow gradually until retirement age. The PER thus functions as a deferred tax optimization tool: you make the savings effort at a time when your marginal tax rate is high, resulting in a lower tax burden upon withdrawal.

The Limitations of Opening a PER Too Early
Before age 30, the situation is more nuanced. The PER remains accessible, but it faces two limitations. On the one hand, young workers rarely have a comfortable savings capacity; on the other hand, their tax burden often remains moderate. Opening a PER very early on may nevertheless be justified in certain cases, particularly when the goal is to establish a long-term savings plan from the very beginning of one’s career or to prepare for an upward career trajectory. In this context, the PER is not so much a tool for immediate tax savings as it is a framework for long-term capital accumulation, to be used with caution given the fees and the lock-in period.
 

Conversely, after age 50, the PER takes on a different character. The accumulation period shortens, but the tax benefits can become particularly significant for high-income taxpayers. Contributions still reduce income tax, and the PER can then serve as a bridge to retirement. In its insurance-based form, it can also be part of estate planning, even if that is not its primary purpose. On the other hand, opening a PER late in life—after retirement benefits have been paid out and there is no longer any earned income—loses most of its appeal, since the tax deduction disappears with the absence of earned income.
 

Age, however, is not the only deciding factor. Income level, consistency in saving, and the plan’s fees are just as important. A PER does not require a high income to open, but it does require a level of savings discipline that is consistent with the management, trading, or transfer fees it entails. For high-income earners, it becomes a tax tool in its own right; for those with more modest incomes, it should be compared with other, more flexible investment options before being selected.
 

Finally, the issue of retirement savings is now being approached differently for younger people. Since 2024, it is no longer possible to open an individual PER account in the name of a minor. For families wishing to plan ahead for their children’s long-term savings, the Climate Future Savings Plan offers an alternative, with an investment strategy focused on the ecological transition and an automatically defined time horizon. Here again, the amount set aside matters less than the overall consistency of the approach.
 

When it comes to PERs, there is no “perfect” age, but rather a “good time,” which depends heavily on one’s life circumstances. It is this interplay between timing, tax considerations, and personal goals that transforms a simple regulated product into a true wealth-building tool.
