## What Is a Source Country?

A Source Country is the state in international taxation where income arises, which may tax non-residents on such income under domestic law and treaties.

*Also known as: Source State, Country of Source.*

## How Source Country works

A Source Country is the jurisdiction where income is treated as arising, such as where services are performed, property is located or a paying company is resident, and domestic source rules decide which income falls within its taxing reach over non-residents. The United States, for example, taxes nonresident aliens only on US-source income and effectively connected income, and IRS guidance states that most US-source income of foreign persons bears a 30% statutory tax, usually collected by withholding. Where a double tax treaty applies, the source country's rights are often reduced or removed, while the residence country generally relieves any remaining double taxation by exemption or credit.

## Source Country vs Residence Country

Unlike the residence country, which generally taxes a resident's worldwide income, a Source Country taxes only income connected to its territory and usually yields priority under treaty relief rules.

## Example

Illustrative example: A consultant resident in Country A receives dividends from a company in Country B. Country B, as the source country, withholds tax at its domestic rate unless the consultant claims the treaty rate, and Country A then taxes the dividend while granting a credit for the Country B tax, subject to local rules.

## Common misconception

**Myth:** Income earned by a non-resident is only taxable in the country where the earner lives.

**Reality:** A Source Country may tax a non-resident's locally sourced income under domestic law, and a treaty generally limits rather than removes that right for many income types.

## Frequently asked questions

### What is the difference between source country and residence country?

A Source Country taxes income because the income arises within its territory, whereas a residence country taxes a person because of personal connections such as a home or presence, generally on worldwide income.

### Can the source country tax a non-resident?

A Source Country can generally tax a non-resident on locally sourced income, often through withholding, although a double tax treaty may reduce the rate or allocate the right exclusively to the residence country.
