Form 111 and Form 190: How to Report Withholding Tax on Employees and Professionals Without Errors

Any self-employed professional or company that pays salaries to employees, or hires the services of professionals (lawyers, consultants, architects, designers…), almost always takes on an additional obligation to the Spanish Tax Agency (Hacienda): withholding part of that income and paying it in on a quarterly basis via Form 111, then summarising the full year in Form 190. These are two sides of the same obligation, and the most common mistake -the one that causes the most headaches when a notice arrives from the Tax Agency- is that the two don’t match. This guide covers who must withhold, what percentages apply, and how to check that the annual Form 190 matches the sum of the four quarterly returns.

Who has to file Form 111?

Form 111 must be filed by self-employed individuals and companies acting as “payers” and, therefore, as withholding agents for personal income tax (IRPF) on behalf of third parties: anyone paying salaries to employees, anyone hiring a professional who issues an invoice with tax withheld, and also anyone paying certain types of income such as prizes, courses, lectures or intellectual property royalties. Form 111 is not required for services from another self-employed professional who does not apply withholding (for example, those taxed under the objective estimation method, or certain activities not subject to withholding), nor for invoices between companies where no specific withholding obligation exists. Filing is quarterly, within the first twenty calendar days of the month following the end of each quarter, except for the fourth quarter, which is filed during January. Even if no withholding tax was due in a given quarter, if the company has employees or professionals registered, there is generally still an obligation to file the form, even with a nil result.

Withholding rates: employees, professionals and directors

There is no single percentage: each type of recipient has its own rules. Employees have a variable percentage withheld, calculated based on their salary and personal and family circumstances (children, disability, type of contract) under the general IRPF withholding procedure; it isn’t a fixed rate but the result of a formula that the company (or its accounting firm) must recalculate whenever the employee’s circumstances change. Self-employed professionals who invoice for services (law, consulting, training, architecture, etc.) are generally subject to a 15% withholding rate, reduced to 7% during the year they start their activity and the following two years, provided the professional has not carried out a similar activity in the previous year; a reduced rate also exists for those who invoice low amounts and request it expressly by notifying the payer. Directors and board members are subject to a higher rate, with a specific reduction when the paying company has a reduced net turnover. The typical mistake here is applying the default 15% to a professional who actually qualifies for the reduced 7% rate, or failing to update it once they have been active for more than three years.

Reconciling the quarterly Form 111 with the annual Form 190

Form 190 is the annual informative return that summarises, recipient by recipient and by income category (employment, professional activities, directors, etc.), all withholdings made during the year. In theory, the sum of the tax bases and withholdings declared in the four Form 111 returns for the year should match exactly what is reported in Form 190. In practice, mismatches arise for very specific reasons: a professional who registered or deregistered mid-year and is recorded in the wrong quarter, an incorrectly entered tax ID (NIF) that prevents the Tax Agency from correctly cross-checking the data against the recipient’s invoice, withholdings corrected via an amended quarterly return that are never carried over to the annual total, or simply a change of accounting firm that breaks the continuity of the historical record. Before filing Form 190, it’s worth manually adding up the year’s four Form 111 returns, recipient by recipient, and comparing the result against the Form 190 draft: any discrepancy, however small, should be explained before filing, because the Tax Agency automatically cross-checks this data against declared invoices and payroll, and a mismatch usually triggers a formal request for information.

At Zythos Business we manage our clients’ withholdings with that same logic of constant reconciliation: quarter by quarter, we check that what’s declared in Form 111 matches payroll and professional invoices before filing, so that January’s Form 190 is a simple summary rather than a surprise. If you’re self-employed or run a small business and want to stop chasing down mismatches every January, we can make sure your withholdings are correctly calculated and reconciled from the very first quarter.
