Come utilizzare

Seleziona il tipo di persona e il reddito imponibile

Il reddito imponibile è il reddito al netto delle deduzioni (contributi previdenziali, oneri deducibili). Per partite IVA forfettarie usa il reddito al coefficiente di redditività. Per dipendenti usa il reddito complessivo del CU.

Scegli regione e comune di residenza

Le addizionali regionali e comunali si calcolano sul reddito imponibile con aliquote deliberate dagli enti locali. L'addizionale regionale varia dall'1.23% (regioni virtuose) al 3.33% (regioni in piano di rientro sanità). L'addizionale comunale va dallo 0% allo 0.9%.

Scegli il tipo di F24 da simulare

"Saldo + Acconti" mostra il versamento di giugno con saldo anno precedente e primo acconto (40%). "Acconto Novembre" mostra solo il secondo acconto di novembre (60%). "Saldo Giugno" simula il saldo dell'anno corrente.

Attiva il Ravvedimento Operoso se hai superato la scadenza

Il ravvedimento operoso consente di regolarizzare spontaneamente un omesso versamento con sanzione ridotta. La sanzione varia dall'1% (sprint 1-14 gg) al 5% (oltre 2 anni). Si aggiungono gli interessi legali al 2.5% annuo.

Domande frequenti

What is the difference between taxable and net income on Form 24?

Taxable income is calculated by applying the brackets (23%/35%/43%) to taxable income. Net tax is obtained by subtracting deductions (dependent employment, family expenses, medical costs). The F24 model reports taxes calculated on last year's tax (historical method). This simulator calculates gross tax without deductions for simplicity - use the full IRPEF calculator for net results.

How does the calculation of IRPEF installments work?

Con the historical method (most common for IVA games), 100% of the IRPEF due in the previous year are paid upfront: 40% by June and 60% by November. The balance is paid by June of the following year. There also exists a predictive method (accounts calculated based on the estimate of the current year), useful if you expect a reduction in income.

What are Regional and Municipal Supplements?

Local taxes are due in addition to the IRPEF. The regional supplement is payable to the region of residence by December 31st of the reference year. The municipal supplement is payable to the municipality. Both are settled up to balance by June of the following year, without advance payment for employees. Value-added tax payments also include the additional regional supplement (30% of the balance) by November.

When is it convenient to use the Busy Sprint vs Long?

Late payment fine (1-14 days of delay) has reduced penalty to 1% of the due amount - most convenient. After 30 days it rises to 1.67%, after 90 days to 3.75%. Over a year it goes up to 4.29%. It's always convenient to regularize before an audit because ordinary penalties are 30% without penalty reduction.
