Introduction: The dilemma of immobilizing capital or hiring flexibility

Anyone starting a business in Madrid will, sooner or later, face a decision that will shape their cost structure for years to come: Should I rent a traditional office or work from a coworking space? The question seems simple, but behind it lie financial, tax and operational implications that many founders and CFOs discover only after they have signed a three-year commitment contract.

The office market in Madrid has changed. Prices for conventional rentals in central areas such as Chamberí, Salamanca, or Paseo de la Castellana have continued to rise, while the supply of flexible spaces It has become professionalized to the point of offering everything a company needs, without the burden of initial investment or contractual rigidity.

This article doesn't aim to sell one option over the other. What it does is lay out the numbers, analyze the tax implications of each model, and explain why more and more established companies—not just freelancers—are migrating to coworking as a strategic business decision.

Direct comparison: traditional office vs. coworking

Before going into nuances, it's worth looking at the Differences between coworking and a traditional office At a glance. This table summarizes the factors that most impact the profit and loss statement:

Concept

Traditional office

Coworking

Initial investment

High-level: legal deposit (2 months' rent according to the LAU), possible additional agreed guarantees, renovation, furniture, IT equipment

Minimal or none: the space is ready to work from day one

Contract of permanence

Typical: 3 to 5 years, with penalties for early termination

Flexible: monthly, quarterly or hourly, without penalty

Supplies

Tenant's responsibility: electricity, water, internet, cleaning, security

Included in the monthly fee

Administrative management

The company is responsible for: insurance, maintenance, incidents

Outsourced to the space operator

Scalability

Limited: changing offices involves moving, a new deposit, renovations

Immediate: expand or reduce positions as needed

Support services

Independent contracting of each supplier

Reception, meeting rooms, networking events and, in centers like ILCOWORKING & LEGAL SERVICES, the possibility of additionally contracting legal and tax advice

The table speaks for itself, but the details matter. Let's break down each aspect.

Financial analysis: when coworking turns capex into opex

This is where the conversation stops being a matter of preference and becomes a purely financial decision. The difference between capex (capital expenditure) and opex (operating expenditure) is not an accounting technicality: it has direct consequences for your cash flow, your borrowing capacity, and your tax burden.

The real cost of setting up a traditional office

Renting an office space in a business area of Madrid involves, at a minimum, the following expenses before anyone can start working there:

  • Legal bond: The LAU (Urban Leases Law) requires a mandatory deposit of two months' rent for leases for uses other than housing (art. 36.1 LAU). However, it is common for the landlord to request additional guarantees (bank guarantees, additional deposits, or personal guarantees) that can significantly increase the initial outlay. In areas like Chamberí or Salamanca, with rents that can range approximately between 1,200 and 3,500 euros per month for a space of 60-100 m², the sum of the legal deposit and additional guarantees can represent a considerable amount of tied-up capital.

  • Reform and adaptation: An open-plan space is rarely ready to function as an office. Partition walls, electrical installation, air conditioning, raised flooring, and painting can cost, as a guideline, between 300 and 600 euros per square meter.

  • Furniture and equipment: Tables, ergonomic chairs, cabinets, meeting room equipment, switchboard, business router. A reasonably equipped workstation can cost approximately between 800 and 2,000 euros.

  • Registration of supplies and contracts: Electricity, symmetric fiber optic internet, water, liability insurance, cleaning contract, air conditioning maintenance.

All of this is capexAn investment that ties up capital and is amortized over several years. Capital that you cannot allocate to product, marketing, or recruitment.

Which includes a coworking fee

The model of expenses included in coworking fee It works in a radically different way. A monthly fee—which in Madrid can range, as a guideline, from 200 to 500 euros per fixed position depending on the area and services—usually covers:

  • Furnished and equipped workstation

  • Symmetrical fiber high speed

  • Air conditioning, electricity and lighting

  • Daily cleaning and maintenance

  • Access to meeting rooms (with a number of hours included)

  • Reception and management of correspondence

  • Common areas: kitchen, lounge, relaxation areas

  • Professional community and networking events

Is pure opex: current operating expense which, provided that the tax requirements demanded by the AEAT are met (link to the economic activity, documentary justification and accounting registration), is deductible in the year in which it occurs, without depreciation or fixed assets.

The impact on the profit and loss statement

For a company of 3 to 10 people, the difference can be decisive. The following figures are indicative estimates based on typical Madrid market ranges and do not constitute a commercial offer:

Traditional office scenario (indicative estimate for 5 positions in the central area of Madrid):

  • Legal deposit + additional guarantees: variable depending on what is agreed with the landlord

  • Basic renovation: 15,000 – 30,000 euros (indicative)

  • Furniture and equipment: 5,000 – 10,000 euros (indicative)

  • Recurring monthly cost (rent + utilities + cleaning + maintenance): 2,000 – 4,500 euros (indicative)

  • Estimated outlay in the first year: between 48,000 and 96,000 euros approximately

Coworking space (5 fixed workstations):

  • Initial investment: virtually zero

  • All-inclusive monthly fee: approximately between 1,000 and 2,500 euros for the whole package

  • Estimated outlay in the first year: between 12,000 and 30,000 euros approximately

Note: These ranges are for guidance only and may vary depending on location, operator, and services contracted. We recommend requesting a personalized quote.

The difference is not marginal. And most importantly: in the coworking scenario, the monthly fee is an operating expense that, provided the legal and tax requirements are met, can be fully deducted in the year it is paid, whereas in a traditional office a significant portion is an investment that is amortized over several years.

Legal flexibility and operational risk

The trap of contractual permanence

An office rental agreement in Madrid for professional use is governed by the Urban Leases Law (LAU), specifically under the regime for leases for uses other than housing (Title III). The LAU establishes a mandatory deposit of two months' rent (Art. 36.1), although the parties may freely agree on additional guarantees without legal limit in this type of lease, unlike what occurs in leases for primary residences. Furthermore, landlords in premium areas typically require:

  • Minimum stay of 3 to 5 years, with penalties for early termination that can amount to several months' rent.

  • Annual rent review, generally linked to the CPI or agreed indices, which introduces uncertainty into financial planning.

  • Works and maintenance clauses which transfer to the tenant the responsibility of maintaining the premises in the agreed conditions.

  • Limited or prohibited subletting, This makes it impossible to make the most of the extra space if the team is reduced in size.

For a startup that doesn't know if in 18 months it will have 3 or 30 people, or for a professional firm that needs to adjust its structure according to the workload, this rigidity can become a burden.

Month-to-month freedom

In a coworking space, the contractual model is radically different:

  • No mandatory stay: Most operators work with monthly or quarterly contracts, with no penalty for not renewing.

  • Immediate operational scalability: You need two more positions next month, you hire them. You downsize the team, you return the positions. No relocation, no renegotiations.

  • Zero risk of construction or maintenance: Any incident at the facilities is the responsibility of the operator.

  • Possibility of changing space: to move from a workstation in a common area to a private office, or vice versa, without changing buildings.

This operational scalability It is especially valuable in three scenarios: growth-stage companies that cannot predict their size 12 months in advance; distributed teams that need a physical hub without committing to a fixed rental; and established professionals who value flexibility as a competitive advantage.

The differentiator that not all coworking spaces offer: legal and tax services at your fingertips

There is one factor that rarely appears in generic comparisons of coworking vs traditional office, And yet it can represent a significant saving of time and money: the possibility of accessing specialized professional services at the workplace itself.

In a traditional office, tax advice, accounting, or legal consulting are external providers that must be found, hired, and coordinated separately. In a standard coworking space, the situation is the same: you have a desk and little else.

ILCOWORKING & LEGAL SERVICES, Located in the Glorieta de Bilbao (Chamberí, Madrid), the space has built its value proposition precisely on this idea. Professionals and companies working there can hire additionally Legal, tax, and accounting advisory services are available through their specialized division, all from the comfort of your workplace. This is a complementary service, separate from the coworking space fee, which users can add as needed.

This option isn't just a matter of convenience; it's a real operational advantage. A freelancer or SME that centralizes their workspace, tax domicile, and accounting services in the same place—contracting each service as needed—eliminates intermediaries, reduces management time, and gains consistency in their administrative structure. For lawyers, consultants, and legal professionals, this integration makes even more sense, as they operate within an environment designed specifically for their professional activity.

The human factor: community versus isolation

Beyond the numbers, there's one aspect that experienced CFOs and founders increasingly value: the professional environment.

A dedicated office, especially for a small team, can become an isolated space where the same four or five people interact for months at a time. This limits cross-business opportunities, reduces exposure to new ideas, and contributes to team burnout.

A professional coworking space offers something that cannot be bought separately: a active community of professionals People from different sectors, with complementary interests, who share coffee, meeting rooms, and, in many cases, clients and projects. Networking doesn't happen at a specific event, but in everyday interactions.

This doesn't mean that every coworking space is a hotbed of synergies. The quality of the community depends directly on the operator's curation, the members' profiles, and the space's culture. Specialized coworking spaces or those with a defined professional profile—such as those geared toward the legal sector—tend to generate more relevant connections than massive or purely low-cost spaces.

Frequently asked questions about taxation and deductions

Is the coworking fee deductible for Personal Income Tax and Corporate Income Tax purposes?

Yes, provided the legal requirements are met. The coworking fee is a current expenditure linked to economic activity And, as such, it can be deductible for both the self-employed (Personal Income Tax under direct estimation) and for companies (Corporate Income Tax). For the Spanish Tax Agency (AEAT) to accept the deduction, the expense must meet three conditions: be linked to professional activity, to have the corresponding documentary justification (invoice with the correct tax information) and be properly recorded in the accounting or in the mandatory accounting records. Unlike renovations or office furniture, which must be amortized over several years, the coworking fee is recorded as an expense in the year it is paid, simplifying tax management.

Can I register my company's address at a coworking space and deduct the associated expenses?

Yes, provided the coworking space offers a service of tax and corporate domiciliation This service is widely recognized. Many professional centers, including ILCOWORKING & LEGAL SERVICES in Madrid, provide this service, allowing freelancers and companies to use the center's address as their registered business address. The fees for setting up a registered business address are also tax-deductible, provided they meet the same requirements regarding business connection, documentation, and registration. It is important that the service includes the receipt and handling of official correspondence to ensure compliance with commercial and tax obligations.

What about the VAT on the coworking fee?

The coworking fee is subject to VAT (currently 21% in Spain), and this VAT is deductible For self-employed individuals and companies carrying out activities subject to the tax, VAT is deductible, as with any other duly justified professional expense. This means that the actual cost of the fee is the net amount, since the input VAT is offset by the output VAT in the quarterly returns (form 303). In a traditional office, the VAT on rent is also deductible, but not the VAT on certain household expenses if personal and professional use are combined.

Conclusion: the smart decision is not the cheapest, but the most efficient

The comparison between coworking and traditional office It's not about who pays less per month. It's about understanding which model best aligns with your business stage, your growth strategy, and your tolerance for financial risk.

If your company needs a fixed space for more than five years, with a stable team and a brand that requires its own presence, a conventional office may make sense — provided you accept the initial investment and contractual rigidity.

But if you value the flexibility, With the ability to scale seamlessly, the transformation of capex into opex, and access to an active professional community, coworking is not a temporary solution: it is a strategic decision.
