Spanish Form 210: new filing deadlines from 2026

Practical filing checklist

• Identify the taxpayer and exact ownership percentage.
• Separate owner-use days from let days.
• Determine whether rental income can be grouped.
• Classify the expected result: payable, nil or refund.
• Check the 2026 transitional rules before applying the new April timetable.
• Prepare supporting documents and expense evidence before the 2027 form is used.

The deadline checker on this page is an organisational aid. It does not replace a review of the accrual date, grouping conditions, ownership percentages or the actual result of the return.

Preparing for the form used from 2027

Returns filed from 1 January 2027 include more detailed information on days, ownership share and rental expenses. The expanded expense schedule distinguishes, among other items, finance costs and repairs, community fees, contract costs, legal defence, third-party services, utilities, insurance, taxes and charges, doubtful debts and separate depreciation of movable assets, the building and improvements.

The existence of an expense field does not itself mean that every non-resident taxpayer is entitled to use it. The ordinary Spanish rule still distinguishes between residents in the EU/EEA mutual-assistance area and residents in other countries. Owners resident outside the EU/EEA should separate the ordinary filing position from any later rectification or repayment claim based on developing case law.

Why the result of the return matters

Before placing a Form 210 deadline in a calendar, classify four things: the type of income, the accrual year, whether the income is grouped or separate, and whether the return is payable, nil or refundable. The same property can generate different filing windows during the same year if it is partly rented and partly available for owner use.

For jointly owned property, the ownership percentage also matters because Form 210 is filed by taxpayer. A single property therefore does not necessarily mean a single tax return.

Deadlines that do not move to April

The reform does not place every rental return in April. A rental return with a nil result remains due from 1 to 20 January of the following year. A return with a refund result may be filed from 1 February of the following year within the applicable statutory period.

Property sales follow a different rule. A non-resident seller files Form 210 during the three-month period that begins once one month has elapsed from completion. The first month is reserved for the purchaser's 3% withholding through Form 211. For that reason, describing the seller's deadline simply as “four months from the sale” can be misleading.

Separate returns: the special 2026 transition

The new timetable does not start in the same way for grouped and separate rental returns. For separate returns, the new April deadline initially applies to income accrued from October to December 2026. If tax is payable, those returns are filed from 1 to 20 April 2027.

By contrast, separate rental income accrued from April to September 2026 keeps the previous 2026 deadlines that were already running. This transitional rule prevents a filing period from being changed after it had effectively started.

Grouped rental income with tax payable

Spanish rules allow certain rental income to be grouped in one Form 210 when the grouping conditions are met. For grouped income arising in 2026 and later years where the result is tax payable, the return is filed from 1 to 20 April of the following year. Direct debit is available from 1 to 15 April.

Grouping should not be assumed automatically. The income must satisfy the statutory conditions and each taxpayer must still report the proportion corresponding to that person's ownership. Where several people own the property, the filing position must be checked contributor by contributor.

Imputed income: the ordinary filing window now starts in April

Non-resident owners who keep a Spanish urban property available for their own use may have to report imputed real-estate income on Form 210. For imputed income arising in 2026 and later years, the ordinary filing period runs from 1 April to 31 December of the following year. If payment is made by direct debit, the final date is 23 December.

The change is not retroactive to 2025 imputed income. A 2025 return remains under the previous calendar and may be filed during 2026. This creates a practical transition: the new April opening date is first relevant in 2027 for 2026 imputed income.

A useful consequence to remember is that there is no ordinary January-to-March 2027 filing window for 2026 imputed income. The window opens on 1 April. A late 2025 return filed from 2027, however, must use the form then in force, including the newer fields for days and ownership share.
