But what is a family loan?
And, well, nothing else matters. We might struggle to agree on what to have for New Year's Eve dinner, but one thing's for sure: they'll be there for the most important things.
This type of loan is frequently used to cover the down payment on a home, one of the main obstacles when applying for a mortgage, especially among younger buyers.
Difference between a family loan and a donation
According to article 618 of the Civil Code , a donation is defined as an act of liberality by which a person freely disposes of something in favor of another, who accepts it.
For its part, article 1740 of the Civil Code regulates the loan or simple mutuum, which always implies the obligation to return what was received.
| Family loan | Donation |
| There is an obligation to return | No refunds |
| It can be interest-free (0%) | It's a free delivery. |
| It is not taxable, but it must be declared. | It is subject to Inheritance and Gift Tax |
| Requires a contract | Requires writing or justification |
| It is declared using form 600 (exempt) | Tax is paid according to the autonomous community. |
That difference is key for the Treasury, since money received without a contract or repayment can be considered a disguised donation .
How to get a family loan?
For a loan between family members to be valid and not generate tax problems, it must be formalized correctly from the beginning.
The usual process consists of:
- Agree on the amount borrowed.
- Define whether the loan will have interest or will be 0%.
- Set a realistic return period.
- Draft and sign a contract.
- Declare the loan to the Tax Office using form 600.
Requirements to formalize a loan with a family member
Even if it's an agreement between close friends, the loan must meet certain basic requirements:
- Existence of a written contract.
- Clear and consistent market conditions.
- Defined return schedule.
- Justifiable bank transactions (transfers, not cash).
The more it resembles a "real" loan, the fewer problems there will be in the event of a possible audit by the Tax Agency.
Contract for family loans
The family loan agreement must include, at a minimum:
- Date and full details of lender and borrower.
- Total loan amount.
- Interest rate (including 0%).
- Return period and method.
- Possibility of early repayment.
- Consequence in case of non-payment.
Although it is not mandatory, signing it before a notary provides additional legal security, especially when several family members are involved.
What is form 600? Steps to declare it to the Tax Office
The 600 form is the document through which the Tax Office is informed of the existence of a loan between individuals.

Usual steps:
- Sign the loan agreement.
- Download form 600 from the regional tax agency.
- Submit it within the deadline (usually 30 business days).
- Keep a sealed copy.
