What's the difference between LDDS and Livret A?
The LDDS works exactly like the Livret A: same rate, same fortnightly calculation, same tax exemption. The only difference is the ceiling (12,000 euros vs 22,950 euros) and fund allocation: the LDDS finances sustainable development and solidarity economy projects.
Optimal savings strategy
Fill your Livret A first (higher ceiling), then switch to the LDDS. Together, you can save up to 34,950 euros of 100% secure and tax-exempt savings. If you're eligible, the LEP offers an even better rate.
