Panama's territorial tax system: documenting foreign-source income your company receives
Panama taxes companies on income from Panamanian sources, so revenue earned from operations abroad is generally outside the tax. That has made Panama a common base for regional companies. It also makes documentation the thing tax authorities and banks ask about first.

A Panama City consulting company advises clients in Colombia, Guatemala and the US. A small part of its work is for Panamanian clients. Its accountant splits revenue into two lines every month: foreign source, generally outside Panama's income tax, and Panamanian source, taxed. The split is only as good as the documents behind it.
A territorial system
Panama's income tax applies to income from Panamanian sources. Income from activities carried out and consumed abroad is generally foreign source and outside the tax. This territorial principle is a main reason regional companies are based in Panama.
What counts as foreign source depends on the activity. Services delivered to clients abroad, with the work and its effects outside Panama, are the clearer cases. Services delivered to Panamanian clients, or with effects in Panama, are Panamanian source.
Substance rules
Panama's place on EU tax lists in recent years led it to introduce rules on foreign-source passive income, such as dividends, interest and royalties, for certain entities, requiring economic substance in Panama to keep such income untaxed. Companies with passive foreign income should check whether these rules apply.
Documents that support the split
Keep, for each client:
- The contract, showing the client's location and where the service is delivered.
- Invoices, with the client's foreign details.
- Payment records, showing where the money came from.
Tax audits and bank reviews both start with these.
Banks ask the same questions
Banks and their correspondents need to understand a company's sources of funds. A Panamanian company receiving payments from several countries will be asked who its clients are and why they pay. The documents above answer that too.
Where Rivet fits
A Rivet business account accepts registered companies after verification, including Panamanian companies. Approved companies get US account details in their own name on every plan and euro and sterling details from the Growth plan. Each payment is matched to its invoice, which keeps the record of who paid and for what in one place. Rivet is not a bank; regulated partner institutions hold the funds.
