Let a Spanish Property This Summer? October Could Mean Three Tax Returns.

For a non-resident letting on the Costa, October's tax deadline depends on how the owner declares this year's rent. Grouping is an option for qualifying income. Last year's return cannot confirm the choice for 2026.

Separate July-to-September rent with tax to pay means a Modelo 210 — non-resident income tax return for each accrual of rent, per owner, by Tuesday 20 October. Electronic filing with direct debit closes Thursday 15 October.

Validly grouped 2026 rent with tax payable files in April 2027, six months later. The useful check is therefore a written question about your 2026 income. An "annual filer" label leaves that question unanswered.

This covers owners who are non-resident in Spain for tax purposes, have no permanent establishment in Spain and have Spanish rental income with tax to pay. The rules follow tax residence, regardless of passport. Spanish tax residents fall under a different regime.

On 9 July, we said non-resident landlords filed annually with nothing due that July. For owners declaring separately, that was wrong: April-to-June rent with tax to pay still filed 1-20 July. Quarterly grouping ended in 2024; separate filing survived. On 20 July, we reversed our advice without acknowledging it.

The October window opens Thursday 1 October, 16 days from today, and runs to 20 October. You use the existing form.

Our 26 August issue gave the correct dates; our "each quarter's rent" wording there and on 20 July needs precision: one return per accrual, per owner.

Rent accrues when it becomes due, or when collected if that happens earlier. Monthly rent due in July, August and September, declared separately with tax payable, means three returns. A couple owning 50/50 can have three each, covering their respective shares.

The Agencia Tributaria — Spanish tax agency, or AEAT, supplies an illustrative example: an EU-resident individual receives €1,000 monthly, declares separately at 19% and deducts no expenses.

Each monthly return comes to €190; three total €570. The 19% rate covers qualifying EU/EEA residents; the general non-resident rate is 24%.

Holiday-let payments deserve a date check. August rent collected in June can accrue in June and belong to an earlier window. A platform's payout date is not automatically the tax date.

Confirmed September 2026 against AEAT's note on the June 2026 order and its non-resident taxation manual.

A qualifying owner can choose to group a year's rent into one return. The filer records that choice in the box labelled Agrupación — grouping. That choice applies to that return.

Grouping requires the same owner, property, income code, tax rate and payer. Two properties cannot share one grouped return, and grouped rents cannot be offset against each other.

The same-payer condition drops only for rent not subject to withholding, using income code 35 with no payer details. Where a tenant was obliged to withhold tax and did, the owner may have no return to file for that income.

If you file yourself, open last year's filed rental return. An X in Agrupación shows that return was grouped. A separate return has Agrupación blank and a completed Fecha de devengo — accrual date.

The Período/año — period/year box reads "0A" on both. Admirably little help.

Those boxes show how you filed that return. Confirm how to declare 2026 income, taking account of the grouping conditions and any 2026 returns already filed.

This week, send your filer one message naming the property and each owner: "For July-to-September 2026 rent, are we declaring separately or grouping? If separately, how many returns are due from 1-20 October, and are we using direct debit by 15 October?"

In the same message, ask how April-to-June 2026 rent was declared, and request the filed returns and payment receipts. That puts July's position before the person handling your income without presuming the answer.

You remain the taxpayer when you use a gestor — administrative adviser. The owner chooses within the grouping conditions; the filer records it. Our guide to non-resident landlord tax in Spain is the reference to keep beside that check.

For an in-person query, AEAT's Delegación de Málaga — Málaga delegation is at Avenida de Andalucía 2, 29007 Málaga. An appointment is recommended.

The April move, covered on 20 July, remains: validly grouped 2026 rent and October-to-December 2026 rent on either basis file 1-20 April 2027 where tax is payable. Direct debit runs 1-15 April.

January is no longer a filing window for 2026 rental returns with tax to pay. Required zero-result returns for 2026 still file 1-20 January 2027.

For an empty or own-use second home, imputed income has no October deadline. If you had qualifying imputed income in 2025, check that return is filed: its deadline is 31 December 2026, with direct debit until 23 December.

For the property and owner details in that message:

Para el inmueble y cada propietario, ¿las rentas de julio a septiembre de 2026 se declararán por separado o agrupadas? — For the property and each owner, will July-to-September 2026 rent be declared separately or grouped?

If separately, pin down the count and payment method:

¿Cuántas declaraciones hay que presentar del 1 al 20 de octubre y se solicitará la domiciliación del 1 al 15? — How many returns must be filed from 1-20 October, and will direct debit be requested from 1-15 October?

Our read is that a written answer naming the 2026 income gives you more control than an "annual filer" label. It gives you a date and a return count to check for each owner; July belongs in the same exchange, with the receipts.

See you on the paseo — A. and the WaypointSur team, counting the returns as well as the months.
