Tax regulations in Spain govern various financial activities, including family transfers, domestic employment, and property transactions. Under Law 29/1987, undeclared money transfers between family members without an obligation of repayment are classified as donations and subject to Inheritance and Gift Tax. Failure to declare such transfers can result in penalties of up to 150% of the unpaid tax amount. To avoid this classification, taxpayers are advised to document loans with signed contracts and repayment schedules. Recent guidance emphasizes that while receiving a loan is not considered taxable income for Personal Income Tax (IRPF) or Corporate Tax, it must be supported by a written contract. This document should specify the lender, borrower, amount, term, interest rate, and payment method to prevent authorities from treating the transfer as a disguised donation. Although any donation must be declared regardless of the amount, a 10,000 euro threshold exists as a control limit where tax authorities are more likely to scrutinize movements to prevent money laundering or tax evasion. Tax rates and exemptions for donations vary significantly across Spain, as the management of the Inheritance and Gift Tax is devolved to the autonomous communities. The degree of kinship also dictates the tax burden, with closer relatives such as parents, children, or spouses typically benefiting from lower costs compared to cousins or unrelated individuals. Domestic workers face specific IRPF rules; because private employers do not act as withholding agents, the annual income threshold for filing a tax return is lowered to 15,000 euros. Additionally, these workers must be registered with Social Security from their first hour of work. Regarding property, individuals over 65 may qualify for an IRPF exemption on capital gains when selling or donating their primary residence, provided it was their habitual residence for at least three continuous years.
