Monotributo or a US LLC for a UK Freelancer in Argentina?

A British freelancer who has settled in Argentina may still be paid by clients in the UK. The place where the client sits does not remove the need to account for work performed in Argentina. For eligible independent work, monotributo offers a personal registration and one monthly federal payment. A US LLC may help when a client requires an American contracting entity, but the Argentine treatment of the worker's income remains to be addressed.

ARCA's category K ceiling from 1 August 2026 is ARS 126,610,838.75 in gross annual billings, about US$83,300 at the September house conversion. The standard monthly federal total for services at that level is ARS 1,614,446.04, about US$1,060. Lower categories cost less, and provincial turnover tax is a separate charge.

What the two arrangements actually cover

A monotributista contracts personally and pays ARCA, formerly AFIP, a monthly amount covering income tax, VAT, pension and statutory health-fund components. The health component is enrolment with an eligible obra social; private medical cover has its own premium. An LLC contracts through a US legal entity and may provide a payment route a client prefers. It supplies no Argentine immigration status, and a UK sole-trader registration likewise cannot stand in for an Argentine registration where the business is established locally.

The practical distinction is who earned the fee and where the individual did the work. Sending a client's money to a foreign company account does not answer those questions.

The August 2026 numbers behind the choice

ARCA's table effective 1 August 2026 puts category A's annual gross ceiling at ARS 12,009,410.45, about US$7,900, with a standard monthly total of ARS 49,527.18, about US$33. At category H the ceiling is ARS 81,924,660.37, about US$53,900, and the services total is ARS 522,706.68, about US$344. Category K reaches ARS 126,610,838.75, about US$83,300, with a services total of ARS 1,614,446.04, about US$1,060. These are federal figures: exclusions for certain pension or health contributions and provincial charges can change the amount someone pays.

The February–July 2026 ceiling of ARS 108,357,084.05 is obsolete for September. ARCA looks at gross invoices rather than profit or the amount left after payment fees. Its other eligibility measures include premises, electricity and rent where applicable. Recategorisation normally takes place in February and August using recent activity; someone newly registered has no full year of actual receipts yet.

Dividing category K's annual ceiling by twelve gives roughly ARS 10.55 million, a planning figure rather than a separate monthly limit. A change in the sterling exchange rate can lift the peso value of identical UK invoices into a higher category. Each export invoice's conversion therefore matters when comparing the rolling twelve months.

From residence paperwork to a UK client's invoice

A British citizen may enter Argentina visa-free as a visitor for 90 days. Living and freelancing there calls for an appropriate immigration basis and tax registration: a visitor stamp is not a business registration. The digital-nomad permission covers remote activity abroad but does not itself provide a DNI. While a residence application is pending, a residencia precaria is the provisional certificate that can support local procedures.

A foreign resident without an Argentine DNI can apply for a CUIT, the tax identification number, through ARCA's Presentaciones Digitales. For eligible applicants ARCA specifies Alta CUIT personas humanas - Situaciones especiales and Form 460 F/PD. With a CUIT and clave fiscal, the online tax credential, the freelancer can set up the fiscal electronic mailbox, register an activity and category, and create electronic-invoice points of sale.

For a service performed locally but genuinely used abroad, including by a UK client, ARCA specifies a Factura E through Comprobantes en línea and a separate export point of sale. The invoice can be in pesos or foreign currency; its peso equivalent uses Banco Nación's buying rate from the day before issuance. A UK billing address alone does not make work used by an Argentine operation an export. Argentine domestic clients instead receive a Factura C. Invoices, client details and bank transfer records make the difference between the two kinds of sale traceable.

The money arriving is another part of the transaction

The Factura E records a service export, while BCRA's exterior y cambios rules govern its receipt. Those rules differ from the rules for individuals buying foreign currency. An Argentine receiving bank can explain which service-export category and supporting contract or invoice documents it requires for the actual payment route. A balance at Wise, Payoneer or a US LLC, on its own, says little about settlement under those rules.

Bank charges and intermediaries can make the invoice value, the amount credited and the ARCA peso equivalent differ. If the UK client pays an LLC, the contract belongs to that entity and the subsequent payment to the person doing the work needs its own treatment. Locally, ARCA's federal charge also sits alongside Ingresos Brutos, a provincial or city tax on turnover. AGIP administers it in Buenos Aires City and ARBA in Buenos Aires Province; a unified scheme applies where both taxpayer and jurisdiction qualify. Because the starting point is gross receipts, even low-profit work can incur that charge.

The UK treaty and the LLC's US filing bill

HMRC lists the 1996 UK–Argentina Double Taxation Convention as in force since 1 August 1997. It covers specified income and capital taxes, with Multilateral Instrument changes taking effect on staggered dates beginning in 2026. UK tax residence still follows HMRC's Statutory Residence Test for each UK tax year, with P85 relevant where appropriate after departure. The treaty helps address overlapping taxation; it does not prescribe an Argentine invoice format.

The US side can also create administration. For an LLC treated as a foreign-owned US disregarded entity, the IRS says a required Form 5472 goes with a pro forma Form 1120. The initial penalty for failing to file a required Form 5472 correctly is US$25,000. Ownership, US-related-party transactions and entity elections shape the filing duties; a single-member LLC is neither automatically a US-taxed corporation nor automatically free of reporting obligations.

Once billings exceed category K or another monotributo condition fails, Argentina's general VAT and income-tax regime becomes the comparison. An employee of an Argentine company has a different route through employment and CUIL rather than independent invoices. For a freelancer within the limits, the useful choice is between straightforward personal contracting and an LLC that has a genuine commercial purpose plus its own administrative cost.

A working address outside your home

If you need client meetings or a separate base, compare serviced workspace and address permissions with the obligations of renting your own office. Start with coworking spaces available on PlataStar, then have your accountant confirm the address and invoicing arrangement before paying for a package.
