# Panama's territorial tax system: documenting foreign-source income your company receives

Panama generally taxes only income from Panamanian sources. Why companies earning abroad still need careful records, and the substance rules that changed in recent years.

## Key takeaways

- Panama generally taxes companies only on income from Panamanian sources.
- Income from activities carried out and consumed abroad is generally foreign source and not subject to Panamanian income tax.
- Panama has added rules on economic substance for some foreign-source passive income, partly in response to EU listings.
- Contracts, invoices and payment records showing where the activity takes place support the classification.

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:

1. The contract, showing the client's location and where the service is delivered.
2. Invoices, with the client's foreign details.
3. 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.
