The evidence pack for Modelo 210
Keep the return reproducible by income type, accrual period and ownership share.
Direct answer
The useful evidence file starts with the cadastral reference, ownership share and exact income type, then links rent, eligible costs or cadastral values to the relevant accrual period. One annual bank total is not enough.
Working route
Separate taxable events
Keep rented periods, imputed-income periods and any disposal in distinct workpapers with their official income codes.
Reconcile property and owner data
Preserve title, cadastral data, invoices, bank evidence and ownership percentages for each taxpayer.
Keep calculation lineage
Record the rule and residence status used for each deduction or rate, plus the generated return and receipt.
Hard stop
Residence-based expense eligibility, a sale, inherited ownership or mixed rental and private periods require a case-specific review.
