TL;DR

  • Spanish consulates and the UGE-CE in Madrid expect every digital nomad visa applicant to show that they are covered by social security somewhere. For US citizens, that means either registering with Spanish Social Security in Spain, or producing a Certificate of Coverage issued by the US Social Security Administration under the US-Spain Totalization Agreement.
  • The US-Spain Totalization Agreement has been in force since 1 April 1988 (SSA Spain pamphlet). It is the legal hook that lets a US employee or self-employed person stay enrolled in the US system instead of paying into Spain’s.
  • The Certificate of Coverage is not Form SSA-1945 (a different form for a different domestic purpose). It is requested through SSA’s Office of International Programs, either online at opts.ssa.gov or by mail/fax. SSA does not publish a standard turnaround time; practitioners report cases routinely take several months.
  • The agreement was written for detached employees (employer sends worker temporarily for up to five years) and for self-employed people who normally work in one country and temporarily transfer their trade to the other. The “I just want to live in Spain and keep my US job” scenario sits in an awkward middle space, and practitioner reports describe SSA historically declining Certificates of Coverage on that basis. Talk to a US-licensed CPA before assuming you qualify.
  • The Spanish DNV income threshold for 2026 is EUR 2,849 per month for a single applicant – 200% of the 2026 SMI (EUR 17,094/year, Real Decreto 126/2026) applied to the international teleworking visa via Ley 14/2013 and the Spanish immigration framework.
  • US citizens also need to think about the Beckham-style special tax regime, the Foreign Earned Income Exclusion, FBAR and FATCA. This article is informational. Get professional advice before you move.

The scene is a glass-walled consular interview room in Los Angeles, or New York, or Miami. You have your apostilled FBI background check, apostilled birth certificate, translated employer letter, twelve months of bank statements, and a private health policy from a provider authorised to operate in Spain. You have everything on the consulate’s checklist. Then the question comes back across the desk.

“And your Certificate of Coverage?”

You haven’t heard of a Certificate of Coverage. You ask what it is. The answer involves the words “totalisation agreement”, “Social Security Administration”, and “Office of International Programs”, in roughly that order. You leave with a note to call your employer’s HR team in the morning, wondering what this means about your carefully-timed plan for accommodation and travel and school relocation…

Remote Work Europe has been tracking Spain’s DNV since it launched under the Startups Law in late 2022, as we knew how eagerly it was anticipated. There are many success stories to date, however the Americans-specific friction around social security coverage is one of the parts of the process least well documented in general DNV guides, which tend to treat applicants as a single group. US citizens face a specific bilateral framework, with specific paperwork, that other applicants do not.

What the Spanish DNV actually requires from US applicants

The Spanish digital nomad visa, legally the visado y autorización de residencia para teletrabajo de carácter internacional, sits inside Ley 14/2013 on entrepreneurs and international mobility, as amended by Ley 28/2022 (the Startups Law) – see BOE consolidated text, articles 74 bis, 74 ter, 74 quater and 74 quinquies. The general DNV mechanics, income thresholds, family rules, the 80/20 sourcing rule, are covered in our existing piece on Spain’s 2026 digital nomad visa and won’t be repeated here.

What that piece covers more briefly, and what this one is about, is the social security coverage requirement.

Article 74 ter of Ley 14/2013 says applicants must demonstrate compliance with social security obligations. The text is general; it does not name the United States, it does not mention the totalization agreement, and it does not mention Certificates of Coverage. A foreigner can obtain a Spanish Social Security Number (NAF) on passport alone via form TA.1, but full alta in the TGSS generally requires an NIE.

The Certificate of Coverage enters the picture through consular practice. The consulate-by-consulate checklists on exteriores.gob.es – for example the Houston, San Francisco and Washington DC telework visa pages – operationalise the statutory rule one of two ways. Either the applicant registers with Spanish Social Security (as an employee through their foreign employer registering as a Spanish employer, or as self-employed by signing up to RETA, the autónomo regime), or they prove they are covered under a bilateral social security instrument that exempts them from registering in Spain. For US citizens, that instrument is the US-Spain Totalization Agreement, and the document that evidences coverage is the Certificate of Coverage. (Spanish consular pages tend to frame this generically as “an international Social Security agreement”, with “Certificate of Coverage” being the practitioner shorthand.)

Pay into Spain’s system, or document that you are paying into another system Spain recognises through a bilateral agreement. There is no third option that involves not paying anywhere.

Where the Certificate of Coverage comes in

The US-Spain Totalization Agreement entered into force on 1 April 1988 (SSA Spain pamphlet). It does three connected things. It eliminates double Social Security taxation for cross-border workers who would otherwise have to contribute to both systems. It lets workers combine coverage periods from both countries to qualify for benefits. And it sets the framework under which Certificates of Coverage are issued.

A Certificate of Coverage is the document that proves a worker is covered exclusively under one country’s system. When SSA issues a US Certificate of Coverage, the worker, and their employer if applicable, are exempt from paying social security taxes in Spain on the covered earnings. When Spain issues the equivalent in the other direction, it works the same way for the US side.

One source of confusion worth clearing up early. Form SSA-1945 is not the Certificate of Coverage. SSA-1945 is a domestic disclosure form titled Statement Concerning Your Employment in a Job Not Covered by Social Security, used primarily by US state and local government employers under Section 419 of the Social Security Protection Act of 2004 (SSA-1945 official form). It has nothing to do with international agreements. If a consulate, employer, or random forum post tells you to file SSA-1945 for your DNV application, that is incorrect.

The actual mechanism lives at the Social Security Administration’s Office of International Programs. The Certificate of Coverage page is at https://www.ssa.gov/international/CoC_link.html. The online request portal is at https://opts.ssa.gov/s/. Employers and self-employed individuals can request certificates online through the portal, by mail, or by fax. SSA does not publish a standard processing time; practitioners report cases routinely take several months and sometimes longer.

That timeline matters. If your consulate appointment is six weeks away, you cannot wait until afterwards to start the certificate process. The Spain-specific SSA pamphlet lists what SSA needs: full name, dates and places of birth, citizenship, country of permanent residence, US and Spanish social security numbers where applicable, dates of work, and addresses of the employer or self-employment activity in both countries. (The pamphlet lists slightly different fields for employee versus self-employed certificates; check the relevant section before applying.)

The employer problem

For US employees, this is where the process tends to stall.

The Certificate of Coverage is requested by the employer, not the employee. Many US employers, particularly smaller ones without an established international mobility function, have never encountered a totalization agreement before. The phrase “US-Spain Certificate of Coverage” arrives in HR inboxes as a foreign-language problem, in both senses.

The agreement’s detached-worker rule was also designed for a specific scenario: a US employer sends an employee to Spain temporarily for up to five years, to work for the employer or a qualifying affiliate (SSA Spain pamphlet, “Eliminating dual coverage for employees”). The classic case is a Madrid office assignment. What it was not obviously designed for, and what is now the high-volume case, is a US employee choosing to move to Spain unilaterally and keep their US job remotely. (And if they actually have a Madrid office, that could derail the application anyway…)

Practitioner reports (notably from Celia Alliance and other US-Spain immigration specialists) describe SSA historically declining Certificates of Coverage for digital nomad scenarios, on the grounds that the agreement was meant for employer-initiated assignments rather than employees relocating of their own accord. More recent practitioner accounts suggest a shift from 2024 or 2025 onward, with certificates being issued for some DNV cases. The picture is in flux; no public SSA guidance names “digital nomad” or “Spain DNV” scenarios specifically, and the shift sits in practitioner commentary rather than codified policy.

The practical takeaway is that an American applicant cannot assume the Certificate of Coverage will be granted just because the agreement exists. The realistic options are:

  • Persuade the employer to apply, and accept that the application may be refused. If SSA grants the certificate, the employee stays in US Social Security, and Spain accepts that for the DNV. If SSA refuses, the employee will need a different route.
  • Have the employer register as a Spanish employer with the TGSS. This is the route some consulates have insisted on, and it is bureaucratically heavy for a US employer with no other connection to Spain. There are services that help, but the cost and HR overhead can be a deal-breaker.
  • Restructure as a contractor. If the US employer is willing, the employee converts to a 1099 contractor relationship and registers in Spain as autónomo. This shifts the social security question from “Can we get a Certificate of Coverage as an employee?” to the self-employed pathway, discussed in the next section. It also has tax and employment-law consequences in both countries that need professional advice before being attempted.
  • Use an Employer of Record. A Spain-based EOR becomes the employee’s legal employer for Spanish purposes, handling Spanish social security registration and payroll, while the US worker continues to do the work for their US team. RWE covers EOR mechanics in EOR in Europe. EORs solve the consular checklist problem, at a recurring cost.

Each of these has trade-offs. None is universally right.

If you’re self-employed bringing US clients

Self-employed Americans face a different version of the same puzzle.

Under the US-Spain agreement, the general rule for self-employed workers is residence-based: self-employed workers who reside in the US are covered by US Social Security; self-employed workers who reside in Spain are covered by Spanish Social Security (SSA Spain pamphlet, “Eliminating dual coverage for self-employment”). There is an exception for those who normally operate in one country and temporarily transfer their trade or business to the other for up to five years; they remain covered by the country they came from.

For a US freelancer moving to Spain on the DNV intending to stay, the residence-based rule applies. Once you are tax-resident in Spain (generally after 183 days in a calendar year), you are a Spain-resident self-employed person under the agreement, and the natural outcome is Spanish coverage through RETA. Our autónomo Spain digital and self-employment in Spain pieces cover the mechanics.

The exception (US-resident self-employed person temporarily transferring to Spain) is the route through which some American freelancers obtain a US Certificate of Coverage at the DNV stage. Whether SSA accepts that framing has varied case by case in the practitioner reporting. For background on the equivalent EU framework, see A1 certificates and social security in Europe.

The tax shape

The Spanish DNV may unlock access to a special tax regime for some nomads, often called the Beckham regime after the footballer for whom the original 2005 version was created. As modified by the Startups Law (Ley 28/2022, Disposición Final tercera), the regime applies a 24% flat rate on Spanish-source employment income up to EUR 600,000, with the excess taxed at 47%, available for the year of move and the following five tax years (six years total). Confirmed against Article 93 LIRPF consolidated text on BOE and Agencia Tributaria guidance on the special regime for impatriates. RWE has a dedicated piece on Spain’s Beckham Law for remote workers.

For US citizens this interacts with three other things.

The US-Spain Tax Treaty. Signed in Madrid on 22 February 1990 and in force since 21 November 1990 (IRS treaty documents). A 2013 protocol updating the treaty was signed on 14 January 2013 and entered into force on 27 November 2019. It allocates taxing rights and provides a foreign tax credit mechanism. Its saving clause (Article 1(4)) preserves the US’s right to tax its citizens largely as if the treaty did not exist. This is why US citizens keep filing US returns no matter where they live.

The Foreign Earned Income Exclusion (FEIE). Filed on Form 2555. For the 2025 tax year the FEIE amount is USD 130,000; for 2026 it is USD 132,900 (IRS – Figuring the Foreign Earned Income Exclusion; also published in Internal Revenue Bulletin 2026-17). The 2026 base housing amount is USD 21,264 (16% of the FEIE) and the general housing-expense cap is USD 39,870 (30% of the FEIE) before location-specific higher limits. To qualify, an American must meet either the bona fide residence test or the physical presence test (330 full days outside the US in any 12-month period).

The interaction with the Beckham regime. This is where Americans need a US-licensed CPA. A US citizen who elects the Beckham regime is taxed in Spain at 24% on Spanish-source income; on the US side, they still file. Foreign tax credits and the FEIE play out differently depending on income category and source rules. The interaction is genuinely complex and the wrong choice can be expensive.

FBAR and FATCA, don’t forget these

A Spanish bank account is a foreign financial account from the IRS’s perspective.

FBAR (FinCEN Form 114) is required for any US person whose aggregate foreign financial accounts exceeded USD 10,000 at any point during the calendar year. The threshold is aggregate across all accounts, and the filing is electronic to FinCEN.

FATCA reporting on Form 8938 is required when foreign financial assets exceed filing-status- and residence-based thresholds. For taxpayers living abroad those thresholds are materially higher than for US-resident filers: single or married filing separately, more than USD 200,000 on the last day of the tax year OR more than USD 300,000 at any time during the year; married filing jointly, more than USD 400,000 / USD 600,000 respectively (IRS – Do I need to file Form 8938?). Form 8938 is filed with the tax return.

Penalties for non-filing of either are punitive. Both filings are routine for anyone with a Spanish bank account holding everyday living funds.

Practical, not preachy

The Certificate of Coverage question is solvable, but it is not a one-evening admin task. The realistic timeline:

  • Confirm with a US-licensed CPA who handles expat returns whether your situation fits the agreement’s detached-worker or self-employed rules.
  • Start the Certificate of Coverage process with SSA at least three to four months before your consular appointment, knowing the request may be refused and you may need to pivot.
  • Line up a Spanish gestor or abogado to handle the Spain-side registration if the US certificate doesn’t come through.
  • Make the Beckham regime decision with the CPA and the Spanish advisor in the same conversation. Neither professional sees the full picture alone.

This article is informational. It is not legal or tax advice. Americans planning a move to Spain on the DNV should consult a US-licensed CPA familiar with expat tax returns and a Spanish gestor or abogado familiar with the DNV. Consular practice varies between cities, and SSA’s interpretation of the totalization agreement for nomad-style cases is currently in active evolution.
