Working Freelance and Sorting Your Taxes in Buenos Aires

If you are freelancing, consulting, or remote-working from Buenos Aires for more than a few months, you should register as a monotributista. It is cheap, fast, and gets you legitimate. The alternative — being paid into a UK account and quietly ignoring the Argentine side — works for short stays but unravels quickly if you are here long-term, looking for a long lease, or trying to access healthcare.

What Is the Monotributo

The monotributo is Argentina's simplified tax regime for self-employed people and small businesses below certain revenue thresholds. You pay a single flat monthly fee. That fee bundles three things: income tax (impuesto a las ganancias), social security contributions (jubilación), and basic healthcare (obra social). One payment, one form, no quarterly declarations. It is genuinely simpler than the British self-assessment process.

There are eight categories (A through H) based on annual gross revenue. The boundaries are updated for inflation a few times a year. As of early 2026, most British freelancers I know sit somewhere between A and D — meaning they pay roughly ARS 25,000 to ARS 90,000 per month (USD 25 to USD 80 at the blue rate). That is your tax. That is also your healthcare. That is also your pension contribution.

What You Need Before You Register

You cannot register without three things:

1. A CUIT (Clave Única de Identificación Tributaria) — your Argentine tax ID. You get one from AFIP (the tax agency) once you have residency. Foreigners with precaria or DNI can apply.

1. A clave fiscal nivel 3 — your online AFIP login. You set this up at any AFIP office with your DNI. Allow a morning for the queue.

1. An Argentine bank account — needed for direct debit of the monthly monotributo payment. Macro, Santander, ICBC, and Galicia all accept foreign residents with DNI. Brubank (online-only) is the easiest option for newer arrivals.

The order matters. DNI → CUIT → clave fiscal → bank account → monotributo registration. Allow about a month from start to finish if you push it.

Foreign-Currency Invoicing (the Important Bit)

If your clients are abroad — UK consultancy, US tech company, EU agency — you can invoice them in their currency through the factura E (export invoice). This is a legitimate, AFIP-recognised mechanism for service exports. Three things to know:

• You receive in your foreign-currency bank account. Argentine residents can hold a USD account, and recently a GBP account is also possible at some banks. The foreign currency lands in your account directly — there is no obligation to convert it to pesos.
• You declare the income at the official exchange rate (the dollar oficial), not the blue rate. This is favourable to you because the official rate is roughly 30% below the blue rate, so your effective tax is lower than it looks.
• You may be VAT-exempt. Service exports are typically zero-rated for IVA (Argentine VAT). You charge no IVA on the invoice, and the export incentive (the "incentivo al exportador") sometimes adds a small refund.

This is the British freelancer's sweet spot. You earn in dollars or pounds. You declare at the (low) official rate. You pay a flat USD 30-80/month. You convert dollars to pesos at the blue rate when you need to spend locally. The arithmetic, for many people, is dramatically better than UK self-employment.

Get an Accountant

Do not try to handle the AFIP web interface yourself in your first year. The website is famously bad, the deadlines are easy to miss, and a good Argentine contador will save you hundreds of hours of frustration. Budget ARS 60,000-120,000 per month for a freelancer-tier accounting service (USD 50-100). They will:

• Register you with AFIP and get your CUIT and clave fiscal
• Set up your monotributo category and direct debit
• Issue your facturas E each month
• File your annual declaration (DDJJ)
• Tell you when to recategorise (every 6 months, based on actual revenue)
• Manage your obra social membership

The UK Side

Argentina-resident does not automatically mean UK-non-resident. The UK Statutory Residence Test (SRT) determines whether you remain liable for UK tax. The short version:

• If you spend fewer than 16 days in the UK in a tax year and you have established a "home abroad", you are non-resident.
• If you spend 91+ days, the rules get complicated and you should consult an accountant.
• File a P85 with HMRC when you move. This formally notifies them and may unlock a refund of overpaid tax on your final UK pay.
• The UK-Argentina Double Taxation Convention prevents you from being double-taxed on the same income, but you must file claims correctly to access the relief.
