Simulator ISEE 2026 - Estimated Calculation DPCM 159/2013
Calculate the indicative ISEE for the 3 DSU variants: Ordinary (N-2), Current (reduced income >25%), University (scholarship and differentiated tax). DPCM 159/2013 formula: ISR + 20%×ISP / equivalence scale. Include foreign assets IVIE/IVAFE. Values [ASSUMED] - check with CAF or INPS.

Frequently Asked Questions
What is ISEE and how is it calculated?
Equivalent Economic Situation Indicator is the Italian means-test for access to subsidized services (daycare, university, housing, ADI). Formula: ISEE = ISE / q, where ISE = ISR + 20% × ISP (DPCM 159/2013). ISR = total household income (previous year), ISP = net wealth (movable and immovable assets), q = equivalence scale calculated based on family composition.
What is the difference between Ordinary, Current, and University ISEE?
The Standard ISEE uses income from year N-2 and assets as of 31/12 N-2. The Current ISEE is requested when current income has dropped by more than 25% compared to N-2 (unemployment, layoff fund): the ISR uses current income, the ISP remains N-2. The University ISEE applies to scholarships and tiered university fees (L. 232/2016): if the student is independent (own residence ≥2 years + autonomous income ≥threshold), they use their own household; otherwise they use the parents' household.
What does foreign wealth mean in the calculation of ISEE?
Foreign assets (IVIE for real estate, IVAFE for financial activities) must be declared in the DSU and included in the ISP. No franchise applies to foreign assets (the €6,000/member franchise only applies to Italian movable property). Values come from the RW frame of the tax return declaration. The simulator includes a specific field for foreign activities - do not omit it for an accurate estimate.
How does the DPCM equivalence scale 159/2013 work?
Scale of equivalence (q parameter) divides household income to reflect economies of scale. Base values [ASSUMED]: 1.00 (1 member), 1.57 (2), 2.04 (3), 2.46 (4), 2.85 (5), 3.22 (6), +0.35 for each additional member. Adjustments: +0.20 for households with ≥3 children, +0.20 for single parent with minor child, +0.30 for moderately disabled, +0.50 for severely disabled/invalid 100%.
Where is the DSU presented to obtain official ISEE?
The DSU (Substitute Declaration) is available for free at a CAF (Tax Assistance Center) or online on the INPS portal. The DSU is valid for one year from submission, except ISEE Current which needs to be renewed every 6 months. The calculated ISEE is advisory: the certified value may differ based on certified data (CU, 730, notarized acts) and CAF/INPS interpretation.
Does this simulator replace CAF or INPS?
No. This tool is only advisory and uses parameters [ASSUMED] that require verification. The ISEE certified certificate can be obtained exclusively by presenting a DSU to a CAF or through INPS. The simulator values may deviate from the official ISEE for differences in certified data, particularly in certain income categories (income, assistance benefits, exempt income) and normative interpretations. Do not use this tool for formal decisions on access to social services.
How is it used?
- Select the ISEE variant
Choose between Ordinary ISEE (DSU standard), Current ISEE (current income decreasing by >25%), or University ISEE (scholarship and university tax). The variant determines the reference period for the income.
- Insert core composition
Indicate the number of household core members, dependent children and potential presence of disabled individuals. These data determine the equivalence scale parameter (q) in DPCM 159/2013 Attachment 1.
- Insert income and wealth
Insert ISR (taxes paid 2 years prior to year N-2 from 730/IRPEF) and ISP: movable assets (current accounts, stocks), main residence (IMU value), remaining mortgage, other properties, and foreign activities (IVIE/IVAFE from Quadro RW). For ISEE Current, also insert current year's income.
- Interpret the result
The simulator calculates ISR, ISP, and ISE = ISR + 20%×ISP and ISEE = ISE / equivalence scale (DPCM 159/2013). The result is indicative: the official ISEE is obtained by presenting the DSU to a CAF or directly to INPS. Values [ASSUMED] - verify with CAF before professional use.
