Last reviewed: 25 September 2026. This guide assumes that you are tax-resident outside Spain and rent out premises located in Spain without operating through a Spanish permanent establishment. Confirm your residency, who the tenant is, the agreement and any applicable double-tax treaty before using the general rules below. A business lease does not itself establish whether a permanent establishment exists.[10]
If your tenant is obliged to withhold Spanish non-resident income tax (IRNR) and the correct withholding has been made, you normally do not file Form 210 for that rental income. If the tenant is not a withholding agent, Form 210 may instead be necessary; it can also be used to request repayment of excess withholding. This is the crucial distinction missing from many generic Form 210 checklists.[1][2][5]
First check: does the tenant have to withhold?
AEAT expressly says that rent paid to a non-resident for business premises is subject to withholding provided the tenant is obliged to withhold. The withholding agent declares and pays it on Form 216 and identifies the recipient in the annual Form 296. Where the correct withholding has been made, AEAT says the taxpayer need not submit a separate IRNR return for that income.[1] The withholding agent’s Form 216 is not the landlord’s Form 210.[1][8]
A counterexample is a private individual renting outside the scope of an economic activity: AEAT identifies such a payer as not a withholding agent, and says the non-resident landlord remains obliged to declare the rental income. Do not assume every commercial-looking contract automatically causes a valid withholding; establish the payer’s actual status and obtain its withholding documentation.[2][5]
If withholding was missing, insufficient, excessive, or reported against the wrong taxpayer or period, reconcile the contract, invoices, payments and certificates before deciding whether and how to file or seek a refund. A withholding figure must not simply be entered as a credit without documentary support: AEAT requires supporting documents when retentions are deducted from a Form 210 liability.[5] If an applicable treaty affects the outcome, establish treaty residence and supporting certificate rather than presuming an exemption or a lower rate.[5][10]
Taxable amount and allowable expenses
For income without a permanent establishment, the starting point is generally the gross rent, not an automatic net-profit figure. An EU resident, or resident in an EEA state with the required tax-information exchange/assistance framework, can potentially deduct qualifying expenses in determining Spanish taxable income. For an individual, AEAT requires expenses permitted under the Spanish personal income-tax rules and proof that they are directly related to the Spanish income and have a direct, inseparable economic link with the Spanish activity. Its example expressly includes Iceland, Norway and Liechtenstein in the EEA expense discussion.[5][7] A company must test the separate corporate-tax expense rule in article 24(6), rather than assume that the individual rules apply to it.[10]
Keep invoices and allocation records; insurance, repairs or management fees are not automatically deductible merely because they concern the property. The landlord must establish legal eligibility, direct connection, relevant periods and ownership share. AEAT requires a tax-residence certificate from the relevant authority when expenses are claimed under article 24(6).[5][7] For declarations submitted from 1 January 2027, the amended Form 210 introduces an annex breaking down deductible property expenses, along with fields for days and ownership share; this applies irrespective of the income’s accrual date.[4][11]
For timing, AEAT says rental income accrues when it becomes due, or on receipt if payment comes earlier. An unpaid instalment is therefore not invariably ignored; equally, a genuine rent-free period or variation needs to be checked against the contract and facts, not presumed taxable at the old rent.[5]
Which tax rate applies?
The general domestic IRNR rate for this type of income is 19% for tax residents of the EU and qualifying EEA states, and 24% for other taxpayers. AEAT’s current table includes Iceland and Norway at 19% and gives Liechtenstein 19% from 11 July 2021; its worked example likewise applies 19% to an EU, Icelandic, Norwegian or Liechtenstein resident for 2024 accruals.[6][7][10] Check the date of accrual, certified tax residence and any applicable treaty before filing. A UK passport does not establish tax residence; where the taxpayer is UK tax-resident, the domestic general rate is ordinarily 24%, subject to the facts and treaty analysis.[6][10]
The tenant’s withholding is based on the applicable IRNR rules and its status as a withholding agent. A potentially deductible expense for the landlord does not justify assuming that the tenant should withhold on a net rent figure; compare the actual withholding and final liability with professional help if they differ.[1][5][10]
When is Form 210 due if you need to file?
Form 210 can report rent separately per accrual or, if the statutory grouping conditions are met, aggregate it. For rent accrued from 2024, eligible rental income can be grouped annually, not quarterly. Grouping requires the same taxpayer, income type and rate, generally the same payer and the same property. For rental income not subject to withholding, different payers can be grouped if the other conditions hold, using the appropriate income code 35. Different properties cannot simply be rolled into one grouped property entry.[3][5][7]
The 2026 transition is important:
| Rental-income situation, where Form 210 is needed | AEAT filing window |
|---|---|
| Eligible annual grouping of rent accrued in 2024 or 2025 | 1–20 January of the following year (a past window for 2024/2025 accruals as of this review). |
| Eligible annual grouping of rent accrued in 2026 or later | 1–20 April of the following year; 2026 grouped rent: 1–20 April 2027. |
| Separate returns for income accrued through September 2026 | First 20 calendar days of April, July, October or January for income accrued in the preceding quarter. Thus July–September 2026: 1–20 October 2026. |
| Separate returns for income accrued from October 2026 | 1–20 April of the following year; October–December 2026: 1–20 April 2027. |
These are AEAT’s windows for rental income returns with tax payable under the 2026 amendment; do not automatically apply them to refund or nil-result cases. AEAT’s general Form 210 guidance separately specifies refund and zero-result windows, so check the precise return outcome and official instructions before relying on a date.[3][4][11] Direct-debit windows end earlier: typically 1–15 January for the old annual-grouping window or 1–15 April for the new April window.[3][4] The tenant’s Form 216 has its own quarterly filing cycle (monthly for a large-company withholding agent), and Form 296 is annual; these are not substitutes for the landlord’s calendar where the landlord must file.[8]
A practical decision sequence
- Establish the taxpayer and property. Record the owner’s tax residence, whether the owner is an individual or company, the precise premises and ownership share, the lease terms, and whether the income arises without a Spanish permanent establishment.[5][10]
- Identify the payer and withholding. Ask whether this tenant is a withholding agent; obtain the withholding certificate and reconcile amounts and periods with the rent ledger. Correct withholding can remove the landlord’s Form 210 filing obligation for that income, while excess withholding may support a refund claim.[1][2][5]
- Determine income and expenses. Record due dates and earlier receipts, rent adjustments, documentary support for expenses, residence certificate and any treaty position. Do not treat deductions as available to all non-residents.[5][7]
- Choose the correct return and deadline if one is needed. Check whether separate or annual grouping is permitted and apply the accrual-date transition above. For property-income returns submitted from January 2027, check the new expense annex and property fields.[3][4][5]
- Keep VAT separate. AEAT says a lease of premises is normally subject to 21% VAT and the landlord generally files Form 303. That is a separate obligation from IRNR withholding/Form 210; check the landlord’s VAT position and any special facts rather than assuming the income-tax process settles VAT.[9]
Frequently asked questions
Must every non-resident landlord file Form 210 for commercial rent?
No. When an obliged tenant correctly withholds IRNR on the rent, AEAT says the landlord need not file a Form 210 return for that income. If the payer is not a withholding agent, or a refund of excess withholding is sought, Form 210 may be required or useful. Verify the actual treatment rather than relying on the label “commercial premises”.[1][2][5]
Can I deduct my premises’ running costs?
Possibly, under article 24(6) if residence and expense conditions are met. The rules differ for individuals and entities, and expenses must be demonstrated and directly connected with the Spanish income. Residence certification is required when using the expense provision on Form 210.[5][7][10]
Is Form 210 still quarterly for rent?
Not as a blanket rule. From 2024 the permitted grouping period for rental income is annual; separately declared accruals through September 2026 retain the old quarterly filing window, while those from October 2026 move to the following April window. An annual 2026 grouped return is due in April 2027. Quarterly filing by the tenant of withholding on Form 216 is a different matter.[3][4][8]
Can I put two premises on one return?
Do not presume so. AEAT’s grouping condition for income arising from property is that it comes from the same property, alongside the other grouping conditions. Keep each property, owner, tenant and tax-rate combination traceable.[3][5]
