Singapore Expats in Portugal — Tax Guide 2026

By Taxpert Editorial · Last reviewed: 26 April 2026

Singapore does not have a Double Taxation Treaty with Portugal. However, Singapore operates a territorial tax system — meaning Singapore only taxes income sourced in Singapore, not worldwide income. For many Singapore-based expats moving to Portugal, this means most income (foreign dividends, offshore employment income) was already not taxed in Singapore, minimizing double taxation risk in Portugal.

Double Taxation Treaty: No DTT
Tax relief mechanism: Unilateral FTC (Art. 81 CIRS)

Key facts

No Singapore-Portugal Double Taxation Treaty
Singapore's territorial tax: Only Singapore-sourced income taxed in Singapore — most expats' foreign income was already exempt
CPF (Central Provident Fund): Singapore allows withdrawal of CPF on permanent emigration — taxable in Portugal as Cat. H
Singapore dividends: One-tier exempt in Singapore — Portugal may tax as Cat. E at 28%
No Singapore capital gains tax — Portugal 28% applies to portfolio gains

Watch-outs for Singapore expats

⚠

No DTT: Unilateral Portuguese FTC (Art. 81 CIRS) applies but is less comprehensive than treaty protection.

⚠

CPF withdrawal: Permanent emigration from Singapore triggers CPF withdrawal eligibility. Time the withdrawal to optimize Portuguese tax impact — consider filing year and regime.

⚠

Singapore dividends: Since Singapore doesn't tax dividends, there is no FTC available in Portugal on Singapore dividend income — the full 28% Portuguese rate applies.
