4. Corrections of self-assessments for previous periods (maximum 3 years):

Corrections to the declarations may be made within a period of three years from the date on which the initial declaration should have been submitted. After this 3-year period, declaration corrections cannot be submitted through the single window system, but rather you must contact the affected Member State of consumption directly.

For each Member State of consumption in which self-assessment adjustments from previous periods have occurred, the following data must be filled in:

EM Country Code of consumption, exercise and period of the self-assessment whose VAT quota is intended to be corrected, as well as the correction of the VAT quota (which may be positive or negative).

The amount that must be entered in “correction of the VAT rate (EUR)” is the positive or negative difference in the VAT rate declared in the period to be corrected. That is, for example, if the intention is to correct the quota declared in Q1 2022 with respect to the EM consumption Germany, in which 300 euros of VAT quota were declared and as a consequence of a rectification of invoices the quota that should have been declared would be 250 euros, it will be necessary to record:

Consumption EM Country Code: From Germany)

Tax year: 2022

Period: 1T

Correction of the VAT amount (EUR): - 50
