One of the most common misconceptions among EU expats in Spain is that you need a residencia, a padrón certificate, or a Spanish bank account to file income tax. You don't. If you have a NIE number, you can file — and if you spent more than 183 days in Spain last year, you are legally required to.
This guide walks you through every step of filing your IRPF declaration via Renta Web in 2026 using only your NIE. It is written for EU citizens who may not have full Spanish documentation but still have tax obligations in Spain.
Do you need to file?
Spanish tax residency is determined by time spent in Spain, not by whether you have a residencia or are registered on the padrón. You are considered a Spanish tax resident — and must file IRPF — if any of the following apply:
- You spent more than 183 days in Spain during the 2025 calendar year
- Your main economic or professional interests are based in Spain
- Your spouse and/or dependent children reside in Spain
General income thresholds
You are generally required to file if you earned more than:
- €22,000 gross from a single employer
- €15,000 gross if you had two or more employers
- €1,600 from investment income or capital gains
- €1,000 from rental income
- Any amount as a autónomo (self-employed)
Below these thresholds you are technically exempt from filing, but it is often worth doing so anyway if you are owed a refund.
What you actually need
Contrary to popular belief, the list is short:
| Document | Required? | Notes |
|---|---|---|
| NIE number | ✓ Required | Your tax identification number in Spain |
| Spanish IBAN | ✓ If expecting refund | Only needed if you are owed money back |
| Employer certificate | ✓ If employed | Certificado de retenciones — request from your employer |
| Investment statements | If applicable | For stocks, funds, crypto, foreign accounts |
| Social Security payments | If autónomo | Deductible — get summary from your SS account |
| Residencia / Padrón | ✗ Not required | Tax residence is based on days in Spain, not registration |

Filing step by step
All filing is done through the Agencia Tributaria's Renta Web platform at sede.agenciatributaria.gob.es. Use Chrome with auto-translation enabled — the interface is Spanish-only.
Access Renta Web
Choose login method — use Número de referencia
Do not attempt Cl@ve PIN unless you are already registered. It requires a prior in-person registration process.
Get your reference number (if needed)
- Your NIE number
- Support number (número de soporte) from your NIE document — or date of birth depending on document type
- Box 505 from last year's tax return — or the last 5 digits of your IBAN if you didn't file last year
The system will issue you a reference code (REF) immediately. Save it — you'll need it every year.
Confirm your fiscal address
You can use any address where you receive mail. Empadronamiento is not required here.
Access your tax file
Review and edit your declaration
- Datos personales — verify NIE, name, marital status, and fiscal address
- Rendimientos del trabajo — check pre-loaded salary data; add manually if missing (employer NIF, gross salary, tax withheld)
- Actividades económicas — if autónomo, add income, expenses, and Social Security contributions
- Ganancias patrimoniales — stocks, crypto, and other capital gains (purchase price, sale price, date)
Common items to add manually
Renta Web pre-loads data from Spanish sources, but several items are commonly missing and must be entered manually:
| Item | Section in Renta Web | Who needs to add it |
|---|---|---|
| Foreign income | Rendimientos del trabajo / Cap. mobiliario | Anyone with income from outside Spain |
| Freelance / autónomo income | Actividades económicas | Self-employed workers |
| Crypto gains / losses | Ganancias patrimoniales | Anyone who bought or sold crypto |
| Foreign bank accounts | Capital mobiliario | Interest from non-Spanish accounts |
| Rent paid (deduction) | Deducciones autonómicas | Tenants in regions with rental deduction |
| Pension contributions | Reducciones base imponible | Anyone contributing to a pension plan |
Deductions worth checking
Many expats leave money on the table by skipping the deductions section. Navigate to Deducciones and check:
- Rent paid — available in many regions for leases signed before 2015, or through regional deductions
- Donations — up to 80% deductible on the first €150, 35% above that, for registered Spanish charities
- Pension contributions — reduces your taxable base directly
- Regional deductions — vary by autonomous community; Madrid, for example, has deductions for school fees and childcare
- Autónomo Social Security — fully deductible as a business expense

FAQs
Can I file with just a NIE and no residencia?
Yes. Tax residence in Spain is determined by days spent in the country, not by whether you hold a residencia certificate or are registered on the padrón. Your NIE is your tax identification number — it's all Renta Web needs to identify you.
What is the support number (número de soporte) on my NIE?
It's the alphanumeric code printed on your NIE document, usually starting with "E" followed by 8 digits (e.g. E12345678). It's used to verify your identity when generating a reference number. If your NIE document is old and doesn't have this field, use your date of birth instead.
What if I didn't file last year?
Use the last 5 digits of your Spanish IBAN instead of box 505 when generating your reference number. If you don't have a Spanish bank account, contact the Agencia Tributaria directly — they can issue a reference number via phone or in-person appointment.
I am owed a refund. How long does it take?
Typically 2–6 weeks for early filers (April), longer if you file in June. Refunds are paid directly to the IBAN you provide in the declaration. You can check the status at any time under Estado de tramitación in your Renta Web account.
Can I file jointly with my Spanish partner?
Yes, if you are married or in a registered partnership (pareja de hecho). Joint filing (declaración conjunta) is sometimes beneficial when one partner earns significantly less. Renta Web calculates both scenarios and shows you which is more advantageous.
Do I need to declare my foreign bank accounts?
If your foreign account balances exceed €50,000 at any point during the year, you must file Modelo 720 separately — this is a declaration of foreign assets, not an income tax form. Interest earned on those accounts must also be declared in your IRPF under capital income.
What if I made a mistake after submitting?
You can file a declaración complementaria (if you underpaid) or a rectificación (if you overpaid or made an error in your favour). Both can be submitted through Renta Web. Do not file a completely new declaration — it will create a conflict.
- You can file Spanish IRPF with only a NIE number — no residencia or padrón needed.
- Tax residency is based on days in Spain, not administrative registration.
- Use Número de referencia to log in — it's the easiest method for expats without a digital certificate.
- Always download the Modelo 100 PDF after submitting — you'll need it for banks, landlords, and visas.
- The 2026 filing deadline is late June 2026. File early if you're expecting a refund.
