The Agència Tributària de Catalunya (ATC) has published the final register corresponding to the 2021 financial year of all vehicles that are taxed by the tax on CO2 emissions, which the Catalan Government implemented last year.


As a measure of support for citizens, and given the current situation, the Generalitat de Catalunya has frozen tax rates and has not increased them as was foreseen by law this financial year.



The tax rates have been frozen and the increase provided by law for this financial year does not apply


Taxpayers can check the details of the definitive register and the fee they have to pay at the ATC's electronic headquarters, accessing it with the NIF and the registration number (for a specific vehicle) or with digital identification, using the idCAT Mobile or other digital certificate, which allows you to view all the vehicles you own.


Payment dates and channels


Vehicles with direct debit will receive a charge on their account from 7.11.2022 to 21.11.2022.


Regarding vehicles that do not have it domiciled :


  • If you already paid tax the previous year, you can make the payment until 21.11.2022.




To make it easier to pay for vehicles that were already on the register the previous year, the owner will receive a reminder at his address, along with a payment letter with the amount to be paid.


  • Newly taxed vehicles must pay according to the date indicated in the notification they will receive at their address.


If the payment has not been direct debited, you can pay through the ATC's electronic headquarters, on telephone 012, on the ATC telephone number (93 551 51 51), in collaborating financial institutions, at Post offices, and all ATC offices and delegations, by prior appointment.


In the event that, upon receiving the notification to pay the tax, any incorrect information is found, taxpayers can file an appeal by accessing the same consultation page of the register ( atc.gencat.cat/co2padro ) with NIF and registration number or, also, with idCAT Mobile or another digital certificate.



Who pays the tax?


The tax must be paid by natural and legal persons who, during the year 2021, have had their tax domicile in Catalonia and have owned a vehicle (touring vehicle, van or motorcycle). Legal entities without fiscal residence in Catalonia but who, during 2021, have had an establishment, branch or office there and have owned a vehicle domiciled in Catalonia are also required to do so.



Who is exempt?


100% electric vehicles, mopeds, trucks or vehicles over 3.5 tonnes, coaches, vehicles authorized to transport more than 9 people (including the driver) and vehicles adapted for the driving of people with reduced mobility. Vehicles with historic vehicle registration and classic vehicles enjoy a bonus of 100% of the full fee and are therefore not taxed either. Likewise, owners of vehicles that, together, do not exceed the 6 euros fee to be paid do not have to pay the tax.




Where does the collection go?


Everything collected from the tax goes entirely to the Climate Fund and the Natural Heritage Fund, and returns to people through investment in actions to improve the environment; promote sustainable mobility and energy transition with the installation of solar panels or biomass boilers; prevent forest fires and adapt forests to the climate emergency; conserve natural parks; renew the radar network of the Meteorological Service of Catalonia to predict extreme phenomena, and promote research and business innovation to mitigate climate change.
