Superbonus 110%: what it is and what requirements you must have

The Superbonus 110% was introduced with Decree n.34/2020 (Relaunch Decree, art.119), then converted into Law n. 77/2020. It allows to carry out building renovation interventions aimed at improving the energy of existing buildings (Ecobonus), and for improving safety from seismic risk (Sismabonus), obtaining a tax discount of 110%.

Below is the complete and updated guide on all the news of the Superbonus 110%, from the requirements to the admitted jobs.



How does the Superbonus 110% work?


The Superbonus 110%, introduced by the Relaunch decree, is an incentive that allows beneficiaries to carry out works to improve energy performance and retrain seismic safety without having to incur any type of cost.

The period of validity of this incentive is to be used for beneficiaries who carry out the renovations starting from 1 July 2020 until 31 December 2022 (in some cases until 2023).

Thanks to the Superbonus 110%, you will be able to count on a 110% deduction of the expenses incurred for the redevelopment interventions, with the limitation to no more than two properties owned.

The deductibles also include the expenses necessary for carrying out the works, such as costs relating to design, disposal and the fees of professionals and appraisals.

Those who do not want to use the tax credit have two other options to choose from: the discount on the invoice or the assignment of the credit to a third party such as banks and financial intermediaries, carrying out the work at no cost.


What are the access requirements for the Superbonus 110%?


Some access requirements (or restrictions) are required to take advantage of the Superbonus 110%:


In order to proceed with the disbursement of the bonus, an improvement of at least 2 energy classes must be guaranteed, or, if this is not possible, of a single class, but the highest achievable.

The improvement of the energy classes must be certified through an Energy Performance Certificate (APE), issued by a qualified technician.



The bonus can also be paid if the interventions contribute to reducing the seismic risk. In this case the only requirement is that the properties are located in the seismic zone 1, 2 or 3. Taking advantage of the seismic adjustment it is possible to opt for a deduction of 905 on the purchase of an anti-disaster insurance policy.


What interventions are allowed by the Ecobonus?


Driving and towed interventions are allowed in the Ecobonus. Towed interventions must be carried out simultaneously with at least one of the following driving interventions:

The insulating materials used must comply with the minimum environmental criteria set out in the decree of the Minister of the Environment and the Protection of the Territory and the Sea of ​​11 October 2017.


Interventions on the common parts of buildings to replace existing winter air conditioning systems with centralized heating systems (for example, heat pump and condensing), cooling or domestic hot water supply.

What documents do you need to be able to apply?


The documentation required to access the Superbonus 110% is quite important and demanding, reaching up to 36 different documents, which is why it is advisable to contact professionals who can follow you step by step.


First you need the green light of the condominium to be able to carry out the work on the common parts, as well as a compliance visa by CAF and accountants to be able to proceed with the request for the bonus and the transfer of credit. However, the visa can be requested after the procedures of the Revenue Agency have started. Furthermore, the Energy Performance Certificate (APE) is required, which must be issued by a qualified technician, who certifies the initial energy class, the final one and the improvement of two energy classes (or the highest achievable) following the execution of the works. The data of the interventions must be communicated electronically, as is the communication to ENEA. The qualified technicians must also provide a certification in which they certify the technical requirements on the basis of the project and the actual implementation. For the purposes of assevering the adequacy of expenses, reference is made to the price lists identified by the decree-law of 4 June 2013, no. 63, referring to the prices prepared by the regions and autonomous provinces, to the official price lists or to the price lists of the local chambers of commerce, industry, crafts and agriculture or, failing that, to the current market prices based on the place where the interventions take place . Qualified technicians must issue this sworn statement issued at the end of the work or for each state of progress of the work.


What are the criticalities of the Superbonus 110%?


The main critical factor concerns the complete absence of cases in which building amnesty is required or, in the worst case, in which there are building abuses. In the case of elements to be remedied, the amnesty must be carried out in full on a date prior to the request for the Superbonus 110%, while in the event of building abuses, which cannot be remedied, the property must necessarily be restored as per cadastral data prior to the request. of the Superbonus 110%. The criticality is also related to the difficulty of the entire procedure, from the bureaucracy to the interventions performed. For this reason it is essential to rely on the Superbonus 110% in the hands of qualified and documented technicians.
