What is the Corporate Tax in Spain?

The corporate tax in Spain (Impuesto sobre Sociedades) is a mandatory annual tax levied on the profits earned by legal entities such as corporations, limited liability companies, and subsidiaries of foreign firms operating in Spain.

Unlike personal income tax, which applies to individuals, corporate tax applies to companies  (whether Spanish or foreign) that generate income within Spanish territory.

All businesses subject to this tax must file a return, even if they have not generated profits during the fiscal year.

The taxable base is calculated from the accounting result (profit or loss), adjusted by specific fiscal corrections such as non-deductible expenses, depreciation rules, or exempt income.

How Corporate Tax works in Spain

Corporate tax is calculated annually, but companies must also make advance payments (known as pagos fraccionados) during the fiscal year.

Here’s how the process works:

1. Determine your accounting profit (net result for the year).
2. Apply fiscal adjustments to arrive at the taxable base.
3. Multiply by the applicable tax rate (25%, 23%, or other special rates).
4. Deduct any tax credits or deductions (e.g., R&D, green investments, regional incentives).
5. Submit the annual corporate tax return (Form 200) to the Spanish Tax Agency between July 1 and July 25 each year.

Companies that operate under specific regimes — such as holding companies, permanent establishments, or foreign subsidiaries — may have additional requirements.
