Tarifa plana (flat-rate contribution)
The tarifa plana is a reduced monthly social security payment of 80 euros for the first 12 months after registering as self-employed, meant to ease the cost of starting a business. After that period, your contribution switches to the standard bracket based on your actual net income.
