Well this year we owe taxes. Income taxes. For the first time since arriving in France we are liable for income tax.
Though not much.
(I did wonder if I made a mistake filling in my tax return, but if I did I can't find it.)
So today I went online to pay it. You have to give them your bank reference because they suck the money out of your bank account. Then you have to warn the bank that they are going to do it, so we need to buy some paper for the printer, quickly !
The website said "You can pay online any time up to 5 days after the date that your taxes are due, and the payment is actually taken from your account ten days after it is due."
