What documents do I need?

The documents you need depend on your service type. Here's a complete checklist for each one. Don't have everything yet? Upload what you have — we'll tell you if anything is missing.

For Imputed Income (property not rented)

• Passport or National ID — identifies you as the taxpayer
• NIE Certificate — your Spanish tax identification number
• IBI Receipt (current year) — shows the cadastral value of your property
• Property Deed (escritura) — confirms ownership. Only needed the first time.

For Rental Income

All of the above, plus:

• Rental contract(s) — one per tenant or rental period
• Rental income records — bank statements or platform reports (Airbnb, Booking)
• Expense receipts (EU/EEA residents only) — mortgage interest, insurance, repairs, management fees, IBI, community fees

For Property Sale

All of the basic documents, plus:

• Original property deed (acquisition) — shows purchase date and price
• Sale deed — shows sale date and price
• 3% retention certificate (Modelo 211) — confirms buyer's withholding
• Acquisition costs — notary, registry, agent fees at purchase
• Sale costs — notary, registry, agent, plusvalía, energy certificate
• Improvement receipts — if you made structural improvements

Tips for better uploads

• Scanned PDF is best — clearest and easiest to read
• Phone photos work too — but make sure the document is flat, well-lit, and all text is readable
• Upload complete documents — all pages, not just the first one
• One file per document type — don't combine different documents in one file
