IMU calculation 2021: how to do it?

In view of the imminent expiry of the deposit, set for June 16, we take stock of instructions to follow.

Per calculate the IMU 2021 deposit you have to start from tax base of the property, to which therate specification set for the reference case.

The rules to keep in mind do not change: for calculate the IMU deposit due by deadline of June 16, 2021 it is necessary to refer to the rates approved by its municipality last year.

When paying the balance, by 16 December, it will be necessary to determine the amount due on the basis of the new regulation and, if necessary, to pay the amount due as an adjustment.

We then make the point in the lines that follow on instructions for calculating IMU 2021, with a profit example numeric.

### Calculation IMU 2021, how to calculate the deposit due on June 16: instructions and numerical example

The introduction of the new IMU which starting from last year also merges the TASI, did not change the rules for calculating the tax payable by all those who do not fall within the exemption cases.

So let’s see, first of all, what is the formula to calculate the IMU 2021.

As already happened in the past years, for the IMU calculation 2021 the following data must be available:

• coefficient of the property;
• rate established by the Municipality.

Obviously it will then be necessary to consider any exemptions or reductions established by their Municipality. The main residence remains exempt from the IMU, with the exception of the luxury ones.

### Calculation IMU 2021: how to determine the tax base

Per calculate the IMU it is necessary to start from tax base, to which the rate established by the Municipality must be applied.

Per calculate the tax base for the purposes ofIMU 2021 deposit it is necessary to consider the different rules envisaged for buildings registered in the land registry, for building areas and for agricultural land.

Starting from buildings registered in the land registry, the tax base consists of the value of the property, determined by applying to the amount of the cadastral income, revalued by 5 per cent, the following multipliers (cadastral coefficients):

Cadastral category Coefficient Type of property
From A / 1 to A / 11 (excluding A / 10) 160 type dwellings: stately, civil, economic, popular, ultra-popular, rural, small villas, villas, castles, palaces of outstanding artistic or historical merit, typical local accommodation
A10 80 Offices or private studios
From B1 to B8 140 Colleges and boarding schools, nursing homes and non-profit hospitals, prisons and reformatories, public offices, schools and laboratories, libraries, museums, galleries, academies, clubs
C/1 55 Shops and shops
C/2, C/6, C7 160 Warehouses and storage rooms, stables, stables, sheds
C/3, C/4, C/5 140 Laboratories for arts and crafts, buildings and premises for non-profit sporting establishments, bathing establishments
D / 1 to D / 10 (excluding D / 5) 65 Factories, hotels and boarding houses, theaters, cinemas, halls for concerts and shows and the like, nursing homes and hospitals, buildings and premises for sports exercises.

Per calculate the IMU 2021 it is therefore necessary to calculate the tax base, determined according to the following formula:

As for the building areas, the tax base is instead constituted by the market value in common trade as of 1 January (or from the date of adoption of the urban planning instruments) considering the following elements:

• territorial area of ​​location;
• building index;
• intended use permitted;
• charges for any land adaptation work required for construction;
• average prices recorded on the market from the sale of areas with similar characteristics.

As for the agricultural and uncultivated land, the tax base consists of the value obtained by applying a multiplier of 135 to the amount of the cadastral income resulting in the land registry, in force on 1 January of the tax year, revalued by 25 percent.

### IMU 2021: how to calculate the down payment. Numerical example

In summary, to calculate the amount due by way of IMU it will be necessary to apply to the taxable base the rate established by the municipality.

Let’s move from theory to practice with a profit numerical example.

Take for example the case of Mr. Bianchi, a taxpayer who owns a second home in the Municipality of Rome belonging to the cadastral category A / 3 and with a cadastral income of € 600.00.

For the calculation of IMU 2021 it will be necessary to proceed in the following way:

• 5 per cent revaluation of the cadastral income> 600 + 5 per cent> 630.00 euros;
• application of the cadastral coefficient> 630.00 * 160> 100,800;
• application of the IMU rate> 100,800 * 10.6%> 1,068.48 euros.

When paying theIMU 2021 deposit it will be necessary pay half of the total due, except for any adjustment to be paid with the December balance on the basis of the new rates approved by the Municipality.

### IMU 2021 calculation: the rates

After analyzing what the instructions to determine the amount of tax due, let us briefly dwell on rates provided.

It is the State that establishes, for each case, thestandard IMU rate. Municipalities have the possibility to increase or decrease it, within the maneuverability margins established by national law.

Below is a table provided by the MEF with the rates and the rules provided for each case:

case in point reference standard rate established by law minimum rate that can be established by the municipality maximum rate that can be established by the municipality ex Tasi surcharge (Article 1, paragraph 755, of Law No. 160/2019)
main house of cadastral category A / 2, A / 3, A / 4, A / 5, A / 6, A / 7 art. 1 C. 740, L. n. 160/2019 Free Free Free not expected
main residence of cadastral category A / 1, A / 8 and A / 9 (* a deduction of € 200 applies) art. 1 C. 748, L. n. 160/2019 0.5 percent * 0 0.6 percent * not expected
buildings of the cadastral group D art. 1 C. 753, L. n. 160/2019 0.86 per cent (0.76 per cent reserved for the state) 0.76 per cent 1.06 percent not expected
buildings built and intended for sale by the construction company, as long as that destination remains and are not in any case leased (goods buildings) art. 1 C. 751, L. n. 160/2019 0.1 per cent (exempt from 2022) 0 0.25 per cent (exempt from 2022) not expected
instrumental rural buildings art. 1 C. 750, L. n. 160/2019 0.1 percent 0 0.1 percent not expected
other buildings (buildings other than the main residence, buildings of cadastral group D, goods buildings, rural instrumental buildings) art. 1 C. 754, L. n. 160/2019 0.86 per cent 0 1.06 percent 1.14 percent
building areas art. 1 C. 754, L. n. 160/2019 0.86 per cent 0 1.06 percent 1.14 percent
Agricultural land (if not exempt pursuant to art.1, paragraph 758, law no. 160/2019) art. 1 C. 752, L. n. 160/2019 0.76 per cent 0 1.06 percent not expected

To determine the IMU rates is therefore the City Council, with a resolution that must be:

• approved by the deadline for the adoption of the budget for the reference year;
• published on the website www.finanze.gov.it by October 28th of the reference year.

Finally, it should be remembered that from 2021 the municipalities will be able to diversify the IMU rates exclusively for the cases that will be indicated with a specific MEF decree. The limitations on the power of diversification will operate, however, only after the date of adoption of the decree and therefore possibly also after the current tax year.
