How to calculate rent withholding and Model 115

Step-by-step guide to correctly calculating IRPF withholding and VAT on a commercial or professional property lease.

Enter the base rent

Type the monthly amount agreed with your landlord before VAT — the taxable base of the lease.

Select the rental type

Business premises (withholding + VAT apply) or residential property (no withholding or VAT). The withholding obligation only exists for economic-activity leases.

Calculate the Model 115 amount

The calculator shows you the monthly withholding and the quarterly total for Model 115, which you must file in the first 20 days of April, July, October, and January.

Note the Model 180 figure

Model 180 is the annual informative summary of all withholdings, filed in January of the following year. The calculator gives you the accumulated annual figure in advance.
