I found a 5-year-old SQUIRREL savings bond taken out in 1992, what are the repayment terms, interest, taxation
Everything depends on the option you will take at the time of reimbursement:
Anonymity or declaration of identity with flat rate deduction or declaration in income.
Depending on the option taken, there will be a very significant difference in the amounts to be collected.
I therefore advise you to go and do simulations on these 3 options with the Caisse d'Epargne, then make your choice according to your personal situation (anonymity, tax bracket .......)
