Portugal’s Incentive for Scientific Research and Innovation, known as IFICI, may allow qualifying new Portuguese tax residents to benefit from a special 20% Personal Income Tax rate on certain employment and self-employment income.
For freelancers and technology professionals, an important question is whether this rate applies to all income earned from the same qualified activity, including invoices issued to foreign clients.
Does the 20% rate apply to all freelance income?
Not necessarily.
Under a restrictive interpretation of Article 58-A of the Portuguese Tax Benefits Code, the benefit may depend not only on the professional activity performed but also on the entity for which the activity is carried out.
This means that income received from the qualifying company or entity may benefit from the 20% rate, while income invoiced to unrelated foreign clients may be taxed under the general progressive IRS rates.
The decisive factor is the legal basis under which the taxpayer was admitted to IFICI.
Are invoices issued to foreign clients considered foreign income?
Not automatically.
A service does not become foreign-source income merely because:
- the client is based abroad;
- the invoice is issued to a foreign company;
- payment comes from a foreign bank account; or
- the contract is governed by foreign law.
Where the freelancer lives in Portugal and performs the services from Portugal, the income will generally be treated as Portuguese-source Category B income.
The client’s country is therefore not enough to determine the source of the income.
Can the foreign-income exemption apply?
IFICI beneficiaries may benefit from the exemption method for certain income obtained abroad.
However, the exemption only applies where the income is genuinely foreign-source.
If the services are performed from Portugal, the income will generally not qualify for the foreign-income exemption, even if the client is located in Germany, the United States or another country.
Practical example
Assume that an IFICI-qualified technology consultant:
- invoices €10,000 to the eligible entity supporting the IFICI registration; and
- invoices €100,000 to unrelated foreign clients;
- performs all services from Portugal.
Under the restrictive interpretation:
- the €10,000 may qualify for the 20% rate;
- the €100,000 may be taxed at the general progressive IRS rates;
- the €100,000 would not normally qualify for the foreign-income exemption.
How should the income be reported?
Where the services are performed from Portugal, the income should generally be reported as Category B income in the Portuguese IRS return.
It should not be reported in Annex J merely because the client is abroad.
For taxpayers under the simplified regime, the income will generally be reported in Annex B. Taxpayers with organised accounting will normally use Annex C.
Important distinction between IRS and VAT
The VAT treatment may be different from the IRS treatment.
A Portuguese freelancer invoicing a foreign business may not charge Portuguese VAT because the reverse-charge mechanism applies.
However, this does not mean that the income is foreign-source for IRS purposes.
VAT place-of-supply rules and IRS source rules must be analysed separately.
Conclusion
The IFICI benefit does not necessarily follow the profession alone.
For freelancers with several clients, the 20% rate may be limited to income sufficiently connected with the qualifying entity or activity supporting the IFICI registration.
Income invoiced to foreign clients but earned from work performed in Portugal will generally remain Portuguese-source income and may be taxed at the general progressive IRS rates.
Because the outcome depends on the specific IFICI eligibility route, each case should be reviewed before the annual IRS return is submitted.
