The PEA and the ordinary securities account (CTO) are the two most commonly used wrappers by individuals to invest in the stock market in France. Their operation, taxation, and the securities they accept differ in ways that directly influence the net return of a portfolio. Understanding these differences allows one to structure their savings rather than settling for a default choice.
The First Account Bias: Why Many Investors Start with CTO Unintentionally
The arrival of brokers like Trade Republic, BUX, or Scalable Capital has changed the habits of entering the stock market. These platforms offered only CTOs for several years before opening or announcing the opening of PEAs only starting from 2023-2025.

The result is clear: many investors start with CTO by default, attracted by a simple app, fractional shares, or access to cryptocurrencies. The migration to a PEA occurs later, when the amount becomes significant. This delay sometimes leads to unanticipated capital gains tax costs, as selling positions on the CTO to repurchase them in a PEA triggers taxation on unrealized gains.
To fully understand the differences between securities accounts and PEAs, one must look beyond a simple list of advantages and consider the actual journey of the saver.

Taxation of PEA and CTO: A Gap That Could Narrow
On paper, the tax advantage of the PEA remains clear. After five years of holding, gains are only subject to social contributions. In a CTO, every realized capital gain and every dividend received is subject to the flat tax, which combines social charges and income tax.
This difference in treatment has long been enough to settle the debate in favor of the PEA for any patient investor. The situation could evolve. Recent reports, notably from the Economic Analysis Council in 2024, propose to align the taxation of CTOs and PEAs after five years of holding. Draft finance laws for 2025-2026 being debated in Parliament foresee a comprehensive review of the treatment of capital gains on securities.
Nothing has been voted on at this stage, and neither the timeline nor the final form of such a reform is known. However, the signal is clear: betting all one’s strategy on the sole tax advantage of the PEA carries a regulatory risk in the medium term.
Investment Universe: What the PEA Does Not Allow You to Buy
The PEA limits investment to shares of companies based in the European Economic Area and eligible ETFs. This constraint effectively excludes several asset classes:
- Shares of American, Asian, or emerging market companies purchased directly (excluding eligible synthetic replication ETFs)
- Bonds, derivatives, options, and leveraged instruments
- Cryptocurrencies and foreign small caps not listed on a European exchange
The CTO has no such restrictions. This flexibility explains its growing use among active or diversified profiles. The combined use of PEA and CTO is increasing among those under 35, who favor the PEA as a base for European or global equity ETFs (via synthetic replication) over the long term, while the CTO accommodates assets not eligible for the PEA.
Contribution Limits and Number of Accounts
The PEA imposes a contribution limit per holder (capital gains can exceed this limit; only contributions are capped). Only one PEA is allowed per person. The CTO, on the other hand, imposes no limit and can be opened in unlimited numbers, including joint accounts.
For an investor whose capital exceeds the PEA limit, the CTO becomes a necessary complement, not a choice.
Transmission and Inheritance: An Often Overlooked Angle
The CTO offers an advantage in terms of wealth transmission. Upon the death of the holder, heirs receive the securities with a purge of unrealized gains: taxation on accumulated gains is canceled. This feature makes it a tool for estate planning that the PEA does not offer, as it is closed upon death and gains are subject to social contributions.
For significant estates or long-term transmission strategies, this gap changes the game. A CTO funded over several decades can transmit a net value greater than that of an equivalent PEA, despite a heavier current tax burden.
Combining PEA and CTO: The Most Coherent Strategy
These two wrappers serve distinct purposes, and their complementarity explains why the most experienced investors use both simultaneously. A typical allocation might work as follows:
- The PEA receives priority for low-turnover global or European ETFs, to maximize the tax advantage on compounded gains
- The CTO accommodates assets excluded from the PEA (bonds, direct non-European stocks, structured products) and serves as a tactical pocket
- Contributions first fund the PEA up to the limit, then shift to the CTO
This distribution is not fixed. It depends on the investment horizon, risk tolerance, and potential liquidity needs. A withdrawal from a PEA of less than five years leads to its closure, which penalizes short-term flexibility. The CTO allows withdrawals without duration constraints.
The choice between PEA and CTO is not limited to a fixed comparative table. Ongoing discussions about tax reform, the gradual expansion of PEA offerings among neo-brokers, and wealth transmission strategies create an environment where the right answer depends on the investor’s complete profile, not a single rule.
