The PEA and the ordinary securities account both allow for stock market investment, but their tax treatment diverges on several key points. Recently increased flat tax, rising social contributions, deposit limits, investment universe: the differences between these two wrappers can be measured in concrete percentages. This article compares the updated tax data for 2026 to clarify the terms of the choice.
Taxation of PEA and ordinary securities account in 2026: updated comparative table
The reforms that came into effect at the beginning of 2026 modify the tax equation of the two wrappers. The table below summarizes the key parameters.

| Criterion | PEA (after 5 years) | Ordinary securities account |
|---|---|---|
| Income tax (capital gains) | Exempt | 12.8% (flat tax) |
| Social contributions | 18.6% | 18.6% |
| Overall rate on gains | 18.6% | 31.4% (PFU) |
| Deposit limit | 150,000 euros | None |
| Investment universe | Eligible stocks and ETFs (EU) | All global markets, all products |
| Number of accounts per person | One only | Unlimited |
The single flat-rate withholding tax has increased to 31.4% since January 1, 2026, up from 30% previously. This increase results from the rise in social contributions from 17.2% to 18.6%. For a PEA held for more than five years, only these social contributions apply, bringing the tax burden to 18.6% instead of 17.2% previously.
The tax gap between the two wrappers remains 12.8 points on capital gains after five years. A gain of 10,000 euros on a mature PEA leaves 8,140 euros net. The same gain on an ordinary securities account leaves 6,860 euros net. This difference accumulates year after year.

To delve deeper into the advantages of the securities account and the PEA, the comparison must also include transaction fees and the specific constraints of each wrapper.
Tax on financial transactions: a hidden cost on the securities account
Classic comparisons between PEA and CTO often overlook an expense item that weighs on active strategies. Since April 2025, the tax on financial transactions (TTF) is set at 0.4% on purchases of eligible French stocks (companies whose market capitalization exceeds a certain threshold).
This rate applies to each purchase, not just upon resale. An investor who makes several portfolio rotations in a year on a securities account bears this tax with each transaction. On a PEA, the TTF also applies to eligible French stocks, but the lower turnover related to the long-term horizon of the PEA mitigates its relative weight.
Concrete impact on an active trading strategy
A frequently traded portfolio accumulates the TTF with each entry into a position. For an investor who buys and sells French stocks several times a quarter via a CTO, the annual cost of the TTF can exceed that of the brokerage fees themselves. This additional cost remains invisible in gross performance statements, but it erodes net profitability.
The PEA, due to its long-term holding logic (minimum of five years for the tax advantage), mechanically generates fewer taxable transactions. The TTF at 0.4% therefore enhances the appeal of the PEA for investors targeting French or European stocks over the long term.
PEA deposit limit and diversification: where the securities account gains the advantage
The PEA limits deposits to 150,000 euros. Once this limit is reached, no new contributions are possible, even if the portfolio’s valuation has decreased in the meantime. The securities account has no such limits.
The investment universe constitutes another major constraint of the PEA. Only shares of companies headquartered in the European Union, Norway, or Iceland are eligible, as well as certain ETFs that replicate global indices synthetically. In practice, an investor wishing to hold U.S. stocks, government bonds, commodities, or derivatives directly must go through a securities account.
Three situations where the CTO becomes the logical choice
- The investor has already reached the 150,000 euro limit on their PEA and has additional liquidity to invest in the stock market
- The strategy relies on assets not eligible for the PEA: shares of U.S. or Asian companies held directly, bonds, structured products
- The investment horizon is short (less than five years), which nullifies the tax advantage of the PEA since early withdrawals trigger the closure of the plan or the application of the PFU
PEA before 5 years: the tax penalty that changes the calculation
A withdrawal from a PEA before five years of holding leads to its closure (except in specific cases such as business creation). The gains realized are then subject to the PFU of 31.4%, exactly like on a securities account.
The tax advantage of the PEA is therefore conditional. It only materializes after five full years. An investor anticipating a need for liquidity in the short or medium term loses the entire tax benefit in the event of a premature withdrawal, while having endured the diversification constraints of the PEA during the holding period.
This point directs the reflection towards a complementarity rather than an opposition. The PEA captures the long part of the portfolio (European stocks, eligible ETFs, horizon greater than five years). The securities account accommodates what does not fit into the PEA, whether by nature (non-EU stocks, bonds) or by timing (need for liquidity in less than five years).
The determining parameter remains the gap of 12.8 points of taxation on capital gains after five years. For an investor primarily placing in European stocks with a long horizon, saturating the PEA first before opening a complementary CTO remains the most tax-efficient sequence.
