Questions about this calculator
What does a purchase cost besides the price?
IMT, stamp duty and the registration steps, with the IMT Jovem exemption able to remove part of it for buyers under 35. The calculator totals the lot as one all-in figure.
Do non-residents pay more?
The rules treat non-resident buyers differently, and the calculator applies the set that matches your residency instead of assuming one case for everyone.
Is IMT Jovem automatic?
No. It has conditions of its own. The calculator shows what the exemption saves when they are met - and what you owe when they are not.
Is stamp duty included too?
Yes. IMT and the stamp duty on the purchase are computed together, because the cash you need at the deed is the sum of both and never IMT alone.
