Rendimiento neto (net income)

Rendimiento neto is your income from self-employment minus the deductible expenses of your activity; it is the figure used to calculate both your income tax and your RETA contribution bracket. Keeping your expenses well documented makes this number more accurate.

In practice, rendimiento neto is worked out by adding up what you have invoiced, excluding VAT, and subtracting the deductible business expenses: your monthly contribution, rent for your premises, utilities used for the business, supplies, accounting fees or depreciation. For income tax it is checked quarter by quarter in the prepayments and settled in the annual return. For RETA contributions, social security starts from the same figure, adds back the contribution itself and applies a deduction for general expenses set by the rules.

The typical mistake is to confuse net income with turnover. Invoicing a lot does not mean earning a lot, and choosing a contribution bracket based on income alone often means overpaying. The opposite slip is common too: counting as an expense something without a full invoice or with no link to the business. That expense can be rejected in a review and your net income jumps up.

Rendimiento neto is related to estimación directa simplificada, estimación objetiva and the cuota de autónomos. It comes from your income and expense ledgers and ends up in your quarterly prepayment and annual return. In kontora every invoice you issue and every expense is booked in double entry, so your year-to-date net income is visible at any moment.
