Coworking, serviced office or lease: what you sign

A desk in a coworking space, a private office inside a business center and a whole floor on a lease can land in the same spreadsheet with a similar monthly number. That does not make them interchangeable. Each format sells you a different thing, and what you buy decides what you can claim when something goes wrong.

The last row has a name in the law. A lease is the contract under which one party grants temporary use and enjoyment of a thing in exchange for a price in money, and a lease of real property or of a material part of it must be made in writing. The other three rows have no name of their own in the Argentine Civil and Commercial Code.

Comparing only the monthly fee leaves out what you pay once: furniture, connectivity, a deposit or a guarantee. What it really costs to rent an office builds that calculation for the lease case.

In a lease, the document names a property, a permitted use, a term and a price, and the Civil and Commercial Code fills in whatever the contract leaves out. Currency, rent updates, term and renewal are negotiated clause by clause in the commercial lease guide.

If the operator is a tenant of the building, ask whether your agreement is a sublease and whether the head lease permits that use. Check the owner’s consent or required notification, as applicable, and what happens to your agreement if the head lease ends. The operator’s own tenancy does not by itself determine the type of agreement it signs with you. The procedure is covered in the commercial lease guide.

In coworking and in serviced offices, the document is an agreement drafted by the operator. Check that the agreement states which desk or office you use, from when until when, what the price covers, when the operator may suspend the service, how meeting rooms are booked and what happens if you leave early. Occupying an office with a door does not turn the contract into a lease, and a plan that includes reception and coffee does not automatically make it a services contract.

The Civil and Commercial Code has no chapter for coworking and no figure that names it. What it does have are two neighboring figures and a rule for doubtful cases: when the classification of a contract is in doubt, it is a services contract if the obligation consists in carrying out a certain activity, independently of its result, and a works contract if an efficacious, reproducible or deliverable result is promised. A lease, by contrast, is defined by the temporary use and enjoyment of a thing in exchange for a price in money.

A coworking contract’s classification depends on the agreed obligations, not merely the plan’s name: it depends on what the document promises. If what you buy is a defined space for your team's exclusive use, the figure leans toward a lease. If what you buy is an ongoing service that happens to include a space, it leans toward a services contract. The wording you sign outweighs whatever the operator's brochure calls it.

And the classification changes what you can claim. A lease carries its own rules: the landlord must hand over the property as agreed and keep it fit for the agreed use, subleasing follows a procedure, and the gaps in the contract are filled by the lease chapter. In a services agreement, the rules of that chapter and whatever you wrote apply. In both cases, legal rules fill the gaps left by what the parties agreed, unless a rule is expressly mandatory.

On minimum commitments, the law sets none for a membership: the minimum term, the notice period and the penalty for leaving early are whatever the contract says. In an office lease the parties also set the term, and if the contract stays silent, the Code supplies three years for uses that are not housing.

When the team works from a coworking space, a second decision shows up, and it is one to make before you sign: which address the company is registered at. The taxpayer's address before ARCA is the one Law 11.683 takes from the Civil Code, and ARCA resolution 5809/2026 spells out what that means for a legal person: the place where top, executive or management administration is exercised. If the company runs a single unit of business, that administration is presumed to happen at its seat.

That criterion should guide your choice of plan. An address where mail is simply received is not, on its own, the place where the company is managed. And when the address changes, the new one must be declared within ten administrative business days of the change.

Separate initial corporate registration from an address change. For a legal person’s CUIT application and tax-address declaration, RG 5803/2025 article 11 refers to the documents in Annex II and digital certification, with a paper-filing alternative in the specified cases. For an address change, RG 5809/2026 article 8 lets you select an ARCA-verified address; if it is absent or different, attach one of the proof documents specified by RG 5803. Do not automatically treat the individual taxpayer document list as your company’s formation file: confirm what the particular procedure requires.

The Inspección General de Justicia is the national corporate registration and oversight authority competent for these CABA registrations. RG 4/2022 on SAS address verification was repealed effective 12 April 2024. RG 11/2026, effective 23 September 2026, amends article 60 of Annex A to RG 15/2024: a complementary electronic seat does not replace the physical one. Do not automatically extend that amendment to every entity type or SAS filing. Confirm the specific regime and seat-setting instrument for your company with IGJ or your notary; elsewhere consult the competent registry.

• The contract or authorization in your company's name, with the full address, the desk or office and the term.
• The proof document that fits your filing. If the operator cannot give you a lease, a loan-for-use contract or the owner's authorization, ask which document will support the address.
• If your agreement is a sublease, the legal notification and owner’s consent applicable under the head lease.
• Written confirmation of whether the price covers using the address for filings, for mail or for both, and for how long.

None of these rules mentions coworking as a figure of its own: what gets assessed is the place you work from and the document you present. Whether your case qualifies is decided by whoever reviews the filing, so it is worth confirming before you sign the plan rather than after.

A coworking plan is sold per desk, per office or per day, and the published price carries its own detail: currency, period and the VAT treatment the operator reports. In PlataStar's coworking directory, each venue shows the address, the amenities and the plans the operator publishes, along with the date those facts were read from the operator's own site. A plan with no published price is not shown.

What the tax covers is covered in the real costs of renting an office. Comparing one price with VAT against another without it is comparing badly.

In a lease, the contract defines what the landlord hands over and who does the works. The law obliges the landlord to deliver the property as agreed and to keep it fit for the agreed use; everything else is settled in the same document. A coworking price, by contrast, is sold as a package: reception, cleaning, internet, coffee and meeting rooms come through the front door, while room hours, printing and out-of-hours access may be included or billed separately: check plan by plan.

A two-column spreadsheet is enough to compare them: desk price or rent, VAT, services, meeting rooms, usage hours, deposit or guarantee, and what you pay once. Offices for lease covers the lease side and the coworking directory covers the published plans.

The useful question is not which option is cheaper, but which one puts your team closer to what it will need over the next year.

• How many people work with you today, and how many in six months? Ask how desks are added and on what term, and what options for expansion or for moving floors the lease allows.
• Do you need privacy for calls, client files or difficult conversations? An office with a door inside a coworking space gives privacy; ask what minimum term the operator requires, because the law sets none for a membership.
• How many client meetings do you have each week, and where do you hold them? Ask how rooms are booked and what allowance the plan includes.
• Do you need to register the company's address? Read the section above before booking: the contract and the documents the operator issues decide whether you can.
• How long can you commit? Minimum term, notice period and early-exit penalty are three contract facts, not three details.

When the team is small, keeps changing size and has not settled on a neighborhood, favor the plan with the shortest minimum term the operator publishes. When you know how many desks you need, want your own tables and a price locked for a year, a lease or a serviced office becomes the sensible calculation. How many square meters your office needs turns that decision into floor area.

The operator drafts the coworking contract and you sign it before you occupy the desk: read it with the same checklist you would use for a lease.

• Minimum term, notice required not to renew, and the penalty for leaving early.
• Price, currency, adjustment index and the date of each adjustment.
• What the plan covers and what is billed separately: rooms, printing, overtime hours, parking, out-of-hours access.
• VAT: whether the price is with or without it, and which invoice type they issue in your company's name.
• Use of the address: mail, filings or both, and which documents the operator provides to prove it.
• Who owns the property and, if your agreement is a sublease, what the head lease permits and what notification or consent is required.
• Liability for damage, equipment and data left on the premises, and whether insurance is required.
• Deposit or guarantee: amount, refund conditions and timeline.
• What happens if the operator closes the venue or changes address during your contract.
