Signing and submitting our tax return electronically (without a private mandate)
Last update
This step-by-step tutorial uses screenshots to explain how to sign and submit your tax return electronically via MyGuichet.lu in the case of joint taxation without a private mandate. In other words: how does one proceed when both taxpayers have their own certificate to sign the tax return electronically?
This tutorial will shortly be available in English.
Please also consult our other tutorials, in which we explain:
