Each quarter:

  • Keep a register of income, purchases, expenses, and investment assets.
  • File VAT returns (unless the activity is exempt).
  • Make the income tax advance payment (unless your invoices are required to include IRPF withholding).
  • Remit the IRPF withholding if you have employees on payroll or hire professionals.

At the end of the year, file these declarations:

  • Annual summary of VAT, rental income, payroll and professional withholding.
    • Operations with third parties exceeding €3,000.
    • The income tax return.

In addition to that, you must pay the freelance contribution to Social Security every month.

Quarterly, in the first days of January, April, July, and October. In some cases, it may be advisable to file a monthly return if you want to quickly claim a VAT refund.

All those necessary for the activity. Each expense must be carefully analyzed to see whether or not it can be deducted.

For high returns, once you reach around €60,000 you can consider whether it makes sense to set up a company. Keep in mind that a company involves more bureaucracy than a self-employed individual.

If it is done voluntarily before receiving the Tax Agency’s notice, there will be a surcharge of 1% and an additional 1% for each month that has passed since the tax filing deadline. From the second year, the surcharge will be 15% plus late interest. This surcharge will be reduced by 25% if paid voluntarily once the Tax Agency sends us the assessment.

If a return is filed late in response to a request from the Tax Agency, there will be a penalty of between 50% and 150% of the amount not paid, plus late interest. The penalty can be reduced by 30% if payment is made within the deadlines set by the Tax Agency, and by an additional 40% if no appeal is filed. In the end, the whole thing can amount to a minimum penalty of around 35%.

Freelance: They are only required to keep a record of invoices issued, purchases, expenses, and investment assets. To do this, they must provide the invoices they issued and received, as well as proof of other expenses.

First of all, define the job position to determine the appropriate collective bargaining category.

Process the Social Security enrollment; for this, the worker’s basic data is required:

  • ID card / NIE (number and details)
  • NAF (Affiliation Number)

Enrollments must be completed before the start of services, and the employment contract must be drawn up and signed.

Currently, there are two basic types of contracts: permanent and fixed-term (temporary). A fixed-term contract applies to production circumstances or to replace an employee:

  • Production circumstances: any occasional and unforeseeable increase over the company’s normal activity or fluctuations in workload that result in a mismatch.
  • Substitution: any circumstance that involves reserving the job of the person being covered.

There are two cases to distinguish, common contingency and occupational contingency:

  • Common contingency: the benefit begins on the 4th day.
  • Occupational contingency: the benefit begins the day after the sick leave starts.

There are some exceptions: sick leave for menstruation, disability, and organ donation (from the first day), or termination of pregnancy/gestation from the 39th week (from the day after).

They can last for a maximum of 545 days.

There are two types of dismissals, disciplinary and objective, and these can be proper (justified) or improper (the reason cannot be justified, or the cause that motivates it is not sufficiently justified).

  • Disciplinary dismissal: Based on a serious, culpable breach by the employee. It requires a written notice detailing the facts and a prior hearing.

First, it is essential to consider the Corporations Act to determine what conflict we are dealing with and what legal options are available.

  • It is important for the company’s bylaws to anticipate the various conflict situations that may arise.
  • It is also very important to establish a shareholders’ agreement in advance that sets out the conflict resolution mechanisms, buy-sell clauses, division of responsibilities, exit procedures, and so on.

The first step would be to try to resolve the conflict within the Board of Directors. Going to institutions like the Barcelona Arbitration Tribunal to try to resolve the conflict with a mediator.

The final option should be the judicial route, through the commercial courts.
