Form 111 and Form 190: How to File Withholdings Without Errors

Form 111 and Form 190 are two sides of the same obligation: reporting to the Spanish Tax Agency the withholdings and payments on account made to employees and professionals. The first is the quarterly return that pays in the withheld amounts; the second is the annual informative summary, which must match, down to the last cent, the sum of the four quarters filed. Mixing the two up, or letting them fall out of sync, is one of the most common reasons the Tax Agency opens an inquiry into self-employed workers and small businesses.

Who withholds, and which rates apply?

The party that pays is the one that withholds, not the one that gets paid. A self-employed worker or a company with employees on payroll, or one that hires services from other self-employed professionals (advisors, lawyers, sales agents, trainers, and so on), is required to apply a withholding to that payroll or invoice, pay it in quarterly through Form 111, and issue the recipient a withholding certificate for their own income tax return.

The rates aren’t the same across the board. For employee payroll, the withholding percentage isn’t fixed: it’s calculated on a progressive scale that factors in annual salary, family situation, number of children, or degree of disability, among other things—which is why two employees earning the same gross salary can end up with different withholding rates. For professionals (self-employed workers invoicing for their services), by contrast, the general withholding rate on invoices is fixed, and a reduced rate applies during the year business activity begins and the two years that follow, as long as the professional hadn’t carried out that activity the previous year. It’s common to see invoices from newly self-employed professionals carrying the reduced rate, then switching to the general rate once that period ends; the typical mistake is continuing to apply the reduced rate after it has expired, which then forces a later correction.

Form 111: the quarterly snapshot

Form 111 records, quarter by quarter, the total employment income and professional fees paid out, along with the withholding applied to each, and represents the actual payment of those amounts to the Tax Agency. It’s filed within the first twenty calendar days of April, July, and October for the first, second, and third quarters; the fourth quarter is filed in January, together with the annual summary. A frequent error is forgetting to declare benefits in kind (for example, health insurance paid for an employee), which also carry a withholding, or filing Form 111 without first cross-checking the quarter’s payroll against the register of invoices received from professionals—letting an invoice with withholding slip through unnoticed.

Form 190: the summary that has to add up

Form 190 is the annual informative return that summarizes, recipient by recipient, everything reported across the year’s four Form 111 filings. It doesn’t involve a new payment—it’s a closing of the books with the Tax Agency, which is why the total withholding figure on Form 190 must match exactly the sum of the four quarterly returns filed. If an error crept in during any quarter (a miscalculated withholding, a duplicated invoice, or an employee hired and let go mid-year that got recorded incorrectly), the mismatch tends to surface precisely when preparing Form 190, often forcing a supplementary or corrective filing for one of the quarters before the annual return can be closed out. That’s why it pays to reconcile each Form 111 against payroll and the invoice register within the quarter itself, rather than waiting until January to discover the gap. Form 190 must be filed throughout the month of January of the year following the one being declared.

At Zythos Business, we review our clients’ withholdings every quarter before filing, precisely so that January’s Form 190 is a routine formality rather than a surprise: we cross-check payroll, professional invoices, and filed Form 111 returns, catch incorrectly applied rates or invoices that slipped through, and get the books and withholding certificates ready before an employee or supplier even asks for them. For a self-employed worker or small business, that quarterly review is the difference between closing out the year without a hitch and scrambling to file last-minute corrections.
