You should know that when donating € 50, for example, the church receives € 50, the amount for which a tax receipt is issued. By attaching the tax receipt to your income statement, the tax administration office will decrease your income tax by 66% of the donation. In the end, your financial expense is of € 17 (only in France).
Thank you in advance for your support, and we are always waiting for you in Nancy at our parish.
