Information and documentation that you should have ready when you receive in-person assistance at our offices

We remind you that once you have made your appointment to prepare your Income Tax return and for the process to be effective, it is very important to have a series of data and documentation available, which we detail below.
You will only have to prepare the documentation related to your personal situation and any other documentation in cases where, upon examining the tax data that you will be able to access prior to in-person assistance, differences are determined with those actually obtained.
