# How to calculate net income from the Single Person?

# Gross annual income from the CUD

Since 2015, the employer has delivered the “single certification” which in fact replaces the old CUD, but it is practically the same thing. Retirees, on the other hand, as usual, receive the single certification from INPS (or from another pension institution).

As always, the first needs of the taxpayer are to understand the meaning of the data found on the model, read them, interpret them, extrapolate the most significant data, to be used also for a correct compilation of the 730 model, for the purposes of the tax return. For example, let’s see how to extrapolate the RAL, that is the gross annual income received with the paycheck.

Starting from 2015, the CUD model has been replaced by the 2015 Single Income Certification. In order to read the items included in the new 2015 CUD model, it is necessary to consult the article on how to read the 2015 Single Certification.

## Where to find it

The new Unica certification is made up of two parts: the first part relates to tax data, while the second relates to social security data. One could be led to think that the gross income is the one present on the second page, in the first line (Tax data, point 1: compensation of employees and similar), in reality that is not the gross, but it is only the taxable amount on which to calculate the personal income tax (which in fact is calculated in the next line, at point 11, withholding income tax.

The RAL (gross annual income) can only be read in the second part of the Certification, precisely in the first line of the fourth page (Social security and welfare data, point 1). Here, if the employee is hired with a project contract, he will find the RAL in section 2 “Collab. coordinated and continuous “, point 9. If, on the other hand, he is hired with a contract as a subordinate (fixed or permanent), he will find the RAL in point 1.

## Calculation

Once the gross annual income is found, how is the net calculated? Just take the RAL and subtract the IRPEF applied and the social security contributions paid by the worker.

Let’s assume that the RAL is 20,000 euros. From these it is necessary to subtract:

- the amount on the second page of the CUD, under the item “Withholding taxes”, point 11 “IRPEF withholding taxes. Let’s suppose they are equal to 3,050 euros.
- the amount on the fourth page of the CUD, under “Social security and social security data”, point 6 “Contributions to be paid by the worker withheld”. Suppose they are equal to 2,000 euros. If the worker is on a project basis, he must take the amount shown in point 11 “contributions to be paid by the collaborator withheld”.

At 21,000 euros it will therefore be necessary to subtract 3,050 and 2,000 euros:

21,000 – 3,050 – 2,000 = 15,950 euros is the net annual income.

To find out the net monthly income (i.e. the monthly paycheck), just do 15.950: 12 (or 13 or 14, if the worker has a thirteenth and fourteenth.

# How to calculate net income from the Single Person

Taxpayers each year can calculate independently or with the collaboration of a qualified intermediary (accountant, accountant, CAF, etc.) the amount of their annual taxable income by completing the tax return. For the simpler situations you can use the Model 730, while when other more complex types of income fall into your income situation (for example, when you have a VAT number), the Single Model is used.

What if instead I wanted to do the opposite calculation, that is, from the Single Model obtain the net income? This is a headache that often touches university students grappling with a new school year and the fateful enrollment application to fill out, where to enter a whole series of income information, which often send not only the student, but the whole family into crisis. . So arm yourself with a little patience and a simple calculator: that’s enough to get the net income from the Unico model.

In the Single Model, to obtain net income, you must go to part RN and subtract, from the amount of the line where the total income is indicated, the amount of the line where the net tax is indicated. So: total income – net tax = net income.

In Form 730, on the other hand, you must go to the “IRPEF settlement statement” section and subtract, from the amount of the line where the total income is indicated, the amount of the line where the net tax is indicated. So, again: total income – net tax = net income.

To obtain the total net income (i.e. the total income of all family members), all you have to do is add up all the net income obtained from the various Single Models or 730 Models.

You haven’t filed your tax return yet and therefore you don’t have the Unico form or the 730? Then you can very well get the net income from the CUD: just go to part “B” (relating to income from employment and similar) and here subtract, from the amount indicated in line 1, the amounts of personal income tax withheld during the year.
