Which regime is better for an expat in Italy: Forfettario or Semplificato?

It depends on your situation, income, and expenses.

Flat-rate regime (Forfettario): often the most convenient if your annual revenue is below €85,000, you have few expenses, and you want simplified management. It offers favorable taxation and streamlined compliance.

Simplified regime (Semplificato): useful if you have high expenses, need to recover VAT, or want to combine this accounting regime with the Impatriati tax relief.
