Frequently Asked Questions

How accurate is this calculator?

Our calculator uses real-time data from Spanish government sources and actual installation costs from Costa del Sol. Results are within 5-10% of actual costs for most installations.

When do I receive the tax incentives?

IRPF deductions appear in your next annual tax return. IBI discounts start from the next tax period after you notify your Ayuntamiento. The ICIO exemption is processed at the permit stage before installation.

Are direct government grants included in this calculator?

No. Direct regional grants are excluded because their availability, funding windows, and payment timelines are unpredictable. This calculator uses only stable, reliable tax mechanisms. Treat any direct grant you may receive as an additional bonus.

Can foreigners access these incentives?

IRPF deductions require Spanish tax residency. IBI discounts and regional grants are available to all property owners. Our team helps navigate the requirements for your situation.
