How to pay contractors in Spain

How to choose: four questions for paying Spanish contractors

Euros reach a Spanish IBAN cheaply and fast, so the decision turns on four other questions.

1. How many autónomos, and how much they bill

Pricing splits into a percentage of each payout and a flat monthly fee per contractor. Against a 3% fee, a $29 seat is cheaper once a contractor invoices more than $967 a month, and a $49 seat once they invoice more than $1,633. Below those amounts, or for irregular invoices, the percentage model wins, and a pure transfer service with no subscription costs least of all.

Headcount matters as much as volume. One autónomo with a correct monthly invoice needs a signed contract and a bank transfer. Five means five invoices to check for IVA and retention lines and five contracts to keep current; a platform that collects invoices and pays in batches then earns its fee.

If you pay one contractor occasionally: a usage-based transfer rail. If you pay a standing team: a contractor management platform, priced on your real invoice totals.

2. Whether the invoice you receive is right, and who checks it

A Spanish invoice to a foreign business looks different from one to a Spanish client. Check four things before the first payment:

• No 21% IVA. A service to a business outside the EU is not subject to Spanish IVA; to an EU business it is an intra-Community supply the contractor reports on modelo 349 (agenciatributaria.gob.es, checked 2026-09-28).
• No IRPF retention line. You are not a withholding agent unless you operate in Spain through a permanent establishment.
• An ES VAT number, for EU payers. A contractor supplying services taxed in another member state must be registered in the ROI register of intra-Community operators (agenciatributaria.gob.es, checked 2026-09-28). Check the number in VIES.
• A QR code, from 2027. Under Verifactu, autónomos’ billing software must comply before 1 July 2027 and companies’ before 1 January 2027 (agenciatributaria.gob.es, checked 2026-09-28).

If an auditor or due diligence needs contract, invoice and payment matched per contractor, a raw transfer leaves that to you.

If you only need the money to arrive: a transfer rail. If you need the documents generated or collected with each payout: a platform that produces contracts and closing documents alongside the payment.

3. Where your euros come from

The only conversion question is on your side:

• You hold EUR in an EU account. Pay by SEPA or SEPA Instant. Euro payments within SEPA carry the same terms as domestic ones, and instant ones cost no more than ordinary ones (clientebancario.bde.es, checked 2026-09-28).
• You hold USD or GBP. Convert before the money reaches Spain. Wise showed USD 9.87 to send USD 1,000 to a Spanish account funded by bank transfer (wise.com, checked 2026-09-28). A USD wire into a EUR account is converted by the receiving bank at its own rate.

If you already hold euros: your own bank, or any platform with SEPA payout. If you fund in another currency: a provider that converts at a disclosed rate and pays out locally in EUR.

4. How dependent the autónomo is on you

Spain draws two separate lines. The first is legitimate: an autónomo who earns at least 75% of their income from one client and meets the other statutory conditions is a TRADE, and that contract must be in writing and registered with the public office (Ley 20/2007, checked 2026-09-28). The second is employment: the Workers’ Statute applies to paid work done within another party’s organisation and direction (boe.es, checked 2026-09-28).

Your hours, your tools, your manager assigning daily tasks and no other clients: that is an employment profile, whatever the label. Deliverables, own equipment, own schedule, other clients: a genuine contractor, even at high dependency.

If the engagement is independent: a transfer rail or contractor management platform. If it is independent but single-client, and you want someone else holding the contract to reduce the risk: a Contractor of Record; read the indemnification clause, not the product name. 4dev works as a Contractor of Record, signing as the contracting party for each contractor, which reduces reclassification risk. If it is really a job: an Employer of Record such as Deel, Remote, Multiplier, Oyster, Rivermate or Native Teams, or your own Spanish entity.

Payout rails into Spain in 2026

Sources: SEPA timing, instant-transfer pricing and domestic-equivalent terms from the Banco de España’s Portal del Cliente Bancario; Wise figures from wise.com (both checked 2026-09-28).

There is no currency control: EU law prohibits restrictions on payments between member states and with non-EU countries (TFEU Art. 63, checked 2026-09-28). Since 9 October 2025 every euro-area bank must offer a free verification of payee that compares the name you enter with the name on the IBAN before you send (ecb.europa.eu, checked 2026-09-28).

What the Spanish contractor needs to get paid

To invoice you legally, an autónomo:

• Is in the tax census. Registration goes through modelo 036; the simplified modelo 037 was abolished from 3 February 2025 (agenciatributaria.gob.es, checked 2026-09-28).
• Is registered in RETA. In 2026 the contribution rate is 31.5% and the base is chosen from 15 brackets of real net monthly income, with minimum bases from €653.59 (net income up to €670) to €1,928.10 (over €6,000) (Orden PJC/297/2026, checked 2026-09-28). New autónomos pay a flat €80 a month for the first 12 months, €88.64 with the intergenerational equity levy, and anyone can change their base up to six times a year (seg-social.gob.es, checked 2026-09-28).
• Holds an ES VAT number if you are an EU business. Supplying services taxed in another member state requires registration in the ROI register (agenciatributaria.gob.es, checked 2026-09-28).
• Holds a EUR account in their own name or their S.L.’s name.

A non-EU national on Spain’s digital nomad visa can invoice you too: a self-employed holder may do at most 20% of their work for companies in Spain and needs a contract with the foreign company of at least three months (exteriores.gob.es, checked 2026-09-28).

Documents and tax on your side

IVA. A service to a business outside the EU is not subject to Spanish IVA. To a business in another EU country it is an intra-Community supply, reported by the contractor on modelo 349 (agenciatributaria.gob.es, checked 2026-09-28), and you account for VAT in your own country under the reverse charge. The standard rate of 21% (agenciatributaria.gob.es, checked 2026-09-28) belongs on invoices to Spanish clients.

Withholding. The obligation to withhold IRPF falls on resident companies, resident individuals in business and non-residents operating in Spain through a permanent establishment (agenciatributaria.gob.es, checked 2026-09-28). A foreign client without one pays gross. For a US payer, pay for personal services is sourced where the work is performed, and foreign-source income paid to a non-resident is not subject to NRA withholding (irs.gov; irs.gov, checked 2026-09-28). Collect a Form W-8BEN from an autónomo (W-8BEN-E from an S.L.) and file no 1099. The 1990 US–Spain income tax convention, amended by a 2013 protocol (irs.gov, checked 2026-09-28), matters only for US-source income, such as work done while visiting the US.

What to keep, per contractor:

1. The signed services contract with scope, rate, currency and IP assignment; for a TRADE, the registered written contract.
2. Each invoice as issued, with the Verifactu QR code once the contractor’s software must comply.
3. Proof of payment matching each invoice.
4. W-8BEN or W-8BEN-E (US payers), or the VIES check of the ES VAT number (EU payers).

Verifactu and e-invoicing: what reaches you

Verifactu governs the contractor’s billing software: corporate taxpayers must comply before 1 January 2027 and other taxpayers, including autónomos, before 1 July 2027 (agenciatributaria.gob.es, checked 2026-09-28). From then every invoice carries a QR code (agenciatributaria.gob.es, checked 2026-09-28).

The B2B e-invoicing mandate in Real Decreto 238/2026 applies only when the customer has its seat, a permanent establishment or residence in Spain. It starts 12 months after a ministerial order for businesses above €8 million in turnover and 24 months after for everyone else (boe.es, checked 2026-09-28). A foreign client is outside it.

Where payments to Spain break

• A retention line on the invoice. Templates built for Spanish clients deduct 15% IRPF. Pay the net and nobody remits that 15%, so the contractor is short. Ask for an invoice without it.
• 21% IVA on a foreign business’s invoice. It can mean the contractor lacks your VAT number and treated you as a consumer. Ask for a corrected invoice before paying.
• No ES VAT number in VIES. For an EU payer, an invoice from a contractor outside the ROI register leaves the reverse charge unsupported.
• A payee name mismatch. Verification of payee flags a trade name on the invoice that differs from the account holder’s name, and a payer’s bank or platform may hold the transfer until the names are reconciled.
• USD sent to a EUR account. The receiving bank converts at its own rate; pay in the invoice currency.
• A first-payout KYC hold. Collect the contractor’s ID and census registration at onboarding, not on payday.
• Reclassification. The payment goes through; the risk sits in the relationship. A worker found to be a falso autónomo who was never registered with Social Security brings fines of €3,750 to €12,000 per affected worker (LISOS Art. 40, checked 2026-09-28). The 2021 Rider Law’s presumption of employment applies to delivery work managed through digital platforms (Ley 12/2021, checked 2026-09-28). See the Contractor of Record rating.
