Argentina Extends Foreign Income Tax Deadlines to 2026, Spain Warns of Penalties for Undeclared Vacation Homes

Argentina's tax authority, the Dirección General Impositiva (DGI), issued a resolution extending the payment deadlines for foreign‑source income taxes. Taxpayers and intermediaries now have until October 2026 to remit retained taxes on capital income generated in the first half of the year, with semi‑annual payment schedules for future periods. The DGI also introduced an optional simplified regime allowing a fixed annual payment of roughly USD 309,000 for all foreign capital income.

In Spain, the Agencia Tributaria cautions taxpayers who omitted a second‑home property from their 2025 income‑tax return. Individuals can correct the omission voluntarily by filing a complementary declaration, incurring a surcharge of 1% plus an additional 1% per month of delay (capped at 15%). If the tax agency initiates a review, penalties can rise to 50‑150% of the unpaid tax, plus interest. The rules treat the vacation home as a non‑economic asset subject to imputed rental income under article 85 of the IRPF law.
