Form 202: How Corporate Tax Advance Payments Work in Spain

Form 202 is the self-assessment return used by companies and other Corporate Income Tax (CIT) taxpayers to make advance payments toward the liability that will ultimately be settled in the annual Form 200 return. It isn’t a separate tax, but a prepayment: whatever is paid through each Form 202 during the year is later deducted from the final liability on Form 200, and any excess paid is refunded.

Any company or entity subject to CIT with an open tax period must file it, regardless of size, with a few narrow exceptions — for instance, a newly created entity’s first tax period, when no advance payment is due unless the tax-base method has already been chosen. It must also be filed even when the projected result is negative or nil under the tax-base method, since in that case filing remains mandatory even if the amount due is zero.

Quota method (Art. 40.2) or tax-base method (Art. 40.3): how to choose

Corporate Income Tax law allows the advance payment to be calculated in two ways. The general method, under Article 40.2, takes the full tax liability from the last filed return (normally the previous year) as its reference, subtracts deductions, rebates and withholdings, and applies a fixed 18% rate to the result. This is the default option if nothing is reported to the tax authorities.

The method under Article 40.3, known as the tax-base method, calculates the payment on the proportional share of actual taxable income accumulated from the start of the tax year to the month in which each payment is filed (the first three, nine or eleven months of the year), applying a rate equal to 5/7 of the entity’s tax rate, rounded down. At the standard 25% rate, that works out to 17%. This method is mandatory for companies whose net turnover exceeded €6,010,121.04 in the twelve months before the start of the tax period, and optional for everyone else.

The choice has real cash-flow consequences. If the current year is performing worse than the previous one — lower sales, thinner margins, occasional losses — the tax-base method usually works out cheaper, since payments are based on what the company is actually earning now rather than a better result from the past. Conversely, if the current year is clearly outperforming the previous one, sticking with the quota method can be advantageous, as payments stay anchored to an older, lower liability, deferring the larger payment until the annual return. There’s no universally better option: it’s worth reviewing the year-end forecast before deciding.

Switching to the tax-base method isn’t automatic and isn’t done when filing Form 202: it’s exercised through a census return (Form 036 or 037) during February of the year in which it is to take effect, when the tax period matches the calendar year. Once chosen, the option binds the entity for that year and subsequent years unless expressly revoked, again through a census return filed in the corresponding February.

Deadlines: April, October and December

The advance payment is filed three times a year, within the first twenty calendar days of April, October and December (with the usual extension to the next business day if the deadline falls on a holiday or weekend). Under the quota method, each payment is one-third of the amount calculated on the reference liability. Under the tax-base method, each payment is calculated on the accumulated result for the first three, nine and eleven months of the year respectively, deducting amounts already paid in earlier filings for the same year.

The most common mistake is treating Form 202 as a minor formality and calculating it roughly: forgetting to deduct prior advance payments under the tax-base method, applying the wrong percentage, or failing to check whether switching methods makes sense before February closes — getting locked into the wrong option for another year. It’s also common not to file when the result comes out at zero under the tax-base method, when the filing obligation still applies regardless.

At Zythos Business we review each year which method genuinely suits each company before the February window to switch closes, and we calculate advance payments by cross-checking the actual accounts against amounts already paid during the year, so Form 202 never becomes a poorly calculated prepayment or a surprise on the final Form 200.
