Quarterly charges

Entrepreneurs or professionals under the simplified system have to file four self-assessments in accordance with the model determined by the Minister of Finance and the Civil Service.

In the first twenty days of the months of April, July and October, ordinary self-assessments (form 303) will be made in which a part of the tax liability derived from the simplified system, corresponding to the first, second and third quarters, respectively, will be paid on account.

The final self-assessment tax return (form 303) in which the tax liability derived from the simplified regime for the tax year is determined is filed during the first thirty days of January of the following year.

The payment on account will result from applying a percentage indicated in the Order approving the modules of the simplified system to the tax payable on current transactions.

For the calculation of the income corresponding to each of the first three quarters, the modules and corrective indices referring to 1 January of each year shall be taken.If they cannot be determined on that date, those of the previous year or those existing at the date of the start of the activity, if this is after 1 January, shall be taken.

Entrepreneurs or professionals who carry out activities under the simplified regime shall file form 303 regardless of whether they simultaneously carry out other activities under the general regime.
