Ecobonus 110% and Sismabonus: guide in 8 points

Ecobonus 110% and Sismabonus 110%, which together form the Superbonus (always at 110%). These are the tax breaks for homework on which the government issued two implementing decrees at the beginning of August (sworn statements and technical requirements) and the Revenue Agency a measure with the "implementing provisions". The measures were contained in the relaunch decree, passed into law in mid-July.

Here is a short guide with what you need to know.

1) WHAT ARE THE TIME LIMITS?

The 110% bonuses can be applied to expenses incurred between 2020 July 31 and 2021 December XNUMX.  

2) FOR WHICH JOBS IS THE ECOBONUS VALID (IN GENERAL)?

The list includes several categories of interventions:

• global energy redevelopment of existing buildings or apartments;
• work on the building envelope such as walls, roofs, floors, windows, fixtures, sunscreens, external facades that influence energy (replastering);
• installation of solar panels for the production of hot water or space heating;
• replacement of winter air conditioning systems with systems equipped with condensing boilers, heat pumps (including hybrid or geothermal systems), microgeneration or biomass;
• installation of building automation devices and systems (for example those that allow automatic management of heating or hot water production or summer air conditioning systems).

3) DOES THE 110% RATE ALWAYS APPLY?

No. Basically, the 110% rate only applies to three types of work:

1. thermal coat on at least 25% of the gross dispersing surface;
2. works on the common parts of the buildings which provide for the replacement of winter air conditioning systems with centralized condensing, heat pump systems (including hybrid or geothermal systems, also combined with the installation of photovoltaic systems and related accumulation systems) or microgeneration ;
3. Replacement of winter air conditioning systems in single-family houses with systems for heating, cooling or the supply of domestic hot water with heat pumps (including hybrid or geothermal systems), or with micro-cogeneration systems.

Below is a summary taken from the broader table attached to the implementing decree on the technical requirements:

Surgeries	Maximum deduction (€)	Maximum spend (€)	Deduction rate	Years to spread it over
Global energy redevelopment	100.000		65%	10
Insulation of walls, roofs and floors	60.000		65%	10
Replacement windows and fixtures	60.000		50%	10
Installation of sunscreens	60.000		50%	10
Thermal coat on at least 25% of the gross dispersing surface			110%	5
Solar panels installation		30.000	110%	5
Condensing boilers with seasonal space heating energy efficiency greater than or equal to 90%	30.000		50%	10
Condensing boilers with energy efficiency greater than or equal to 90% on centralized systems		30.000	110%	5
Replacement of winter air conditioning systems with generators equipped with condensing hot air	30.000		65%	10
Replacement of winter air conditioning systems with high efficiency heat pumps		30.000	110%	5
Replacement of winter air conditioning systems with 5-star class biomass boilers		30.000	110%	5
Replacement of traditional water heaters with heat pump water heaters	30.000		65%	10
Building automation systems	15.000		65%	10

BUT ATTENTION: if they are carried out TOGETHER with one of the three works for which the 110% rate is foreseen from the outset (those listed at the beginning of the paragraph), the other interventions also benefit from the bonus with a 110% rate. The spending limits remain, while the number of years over which to spread the deduction is halved from 10 to 5.

4) WHICH DOCUMENTS ARE REQUIRED FOR THE 110% ECOBONUS?

To qualify for the 110% eco-bonus, the works must guarantee the building an improvement of at least two energy classes (or in any case the achievement of the highest energy class that can be obtained), to be certified with the Energy Performance Certificate (Ape), a document that is issued by a certified technician before and after the intervention.

In addition, two other documents must be issued:

• A compliance visa to be sent to the Revenue Agency to certify the existence of the conditions that give entitlement to the bonus; it is issued by accountants, labor consultants and Caf and is used only for the purpose of assigning credit and discounting the invoice (see further on).  
• A certificate (or asseveration) issued by qualified technicians and to be sent to Enea to ensure compliance with energy requirements and the adequacy of the costs incurred.

5) HOW IS THE SISMABONUS CHANGING?

Until July 2020, the Sismabonus had a variable rate between 70 and 85%. With the relaunch decree, the bar rose to 110% for all interventions that improve the seismic class of buildings. There is only one condition: the property must be located in high, medium-high or medium-low seismic risk areas (zones 1, 2 and 3). The maximum expenditure on which to calculate the deduction amounts to 96 thousand euros per year per real estate unit. Finally, like the Ecobonus 110%, the Sismabonus 110% must also be spread over five equal annual installments.

6) WHICH DOCUMENTS ARE REQUIRED FOR THE SISMABONUS?

In addition to any compliance visa (see above), the Sismabonus also requires a document certifying the effectiveness of the works to reduce the seismic risk and the adequacy of the expenses incurred. It is issued by specialized professionals, for example structural engineers.

7) ARE ECOBONUS AND SISMABONUS ALSO VALID FOR A SECOND HOME?

Yes, but not always. The two subsidies also cover work on the second home unless it is a luxury home or a villa. On the other hand, the owners of terraced houses will be able to benefit.

8) HOW DO THE INVOICE DISCOUNT AND CREDIT TRANSFER WORK?

Using the bonus as a tax deduction in the tax return is not the only possibility. There are two more:

1. Discount on invoice equal to 100% of the costs incurred. It is obtained by transferring one's bonus to the company or craftsman responsible for the interventions, who will obtain a tax credit equal to 110% of the cost of the work and can in turn transfer it to banks or financial intermediaries.
2. Transfer of the tax credit. Alternatively, the same taxpayer who is entitled to the bonus can choose to transfer it to a bank, a financial intermediary or – only in the case of the Sismabonus – to an insurance company.
