Cost of a double taxation analysis

Pricing

Fixed fee defined case-by-case after a preliminary consultation, based on the income flows involved, the complexity of the cross-border structure and whether MAP representation is required. The preliminary consultation is a 45-minute paid online session ($250); the engagement letter with the agreed fee is signed before any chargeable work begins.

Double taxation Italy–USA: what clients ask

Do I have to pay tax in both Italy and the US on the same income?

Generally no — the treaty allocates primary taxing rights to one country and grants a credit in the other. Mismatches can occur when entity classification differs (e.g. an LLC treated transparently in the US but as opaque in Italy); this is the most common source of disputes.

How does the foreign tax credit avoid double taxation?

In the US: Form 1116 allows you to credit Italian taxes against US tax on the same income, up to the US tax that would be due on that income. In Italy: art. 165 TUIR allows you to credit US taxes against Italian tax, with similar proportional limits. Timing and allocation rules differ between the two systems.

What are the withholding rates on US dividends paid to an Italian?

Under art. 10: 15% maximum (standard); 5% maximum if the Italian recipient is a company owning at least 25% of the US payer. The default US statutory rate is 30%; treaty reduction requires Form W-8BEN (individual) or W-8BEN-E (entity) on file with the US payer.

Is my INPS pension taxed in Italy or the US if I live in Florida?

Under art. 18: INPS pensions paid to a US resident are generally taxable only in the US (private-sector pensions follow the residence rule). Pensions for former Italian public-sector employees (INPDAP) remain taxable in Italy.

My Italian company has US clients — do I owe US taxes?

Only if the activity creates a US permanent establishment under art. 5 (fixed place of business or dependent agent with contract authority). Pure cross-border sales without US presence generally do not create US tax — but the line is fact-specific and worth mapping before activity scales.

I sold shares in a US company — where are the capital gains taxed?

Under art. 13, capital gains from sale of US company shares by an Italian resident are taxable only in Italy (residence country) unless the seller has or had a US permanent establishment. Real-estate-rich US company shares (USRPHC under FIRPTA) are an exception — those gains are also taxable in the US.

What do I risk if my Italian company operates in the US without formal structure?

PE assertion by the IRS: retroactive US corporate income tax on attributable profits, penalties (typically 20-40% of underpaid tax), interest, and possible state-level liability. The Italian company also remains taxable in Italy on the same income, with credit limited to actual proven US tax. Rule: structure precedes activity.

How does the treaty work for employees in the US with Italian contracts?

Under art. 15: employment income is taxable in the US if the work is performed in the US for >183 days, OR the Italian employer has a US PE bearing the cost. Under both conditions, US tax applies and Italian employer must address withholding obligations. Below 183 days and without PE, remains Italian-taxable only.
