Deductible expenses for self-employed in 2026: The complete guide

What are deductible expenses for the self-employed in 2026 and why they matter to you

Understanding deductible expenses for the self-employed in 2026 is not just an administrative task; it’s a fundamental financial strategy for the health of your business. Every euro you deduct correctly is a euro not subject to taxation, which directly reduces the amount of taxes you pay. In essence, a deductible expense is a cost you incur to generate income, and the Tax Agency allows you to subtract it from your profits before calculating your IRPF. This means more money in your pocket at the end of each quarter and in your annual declaration.

For Hacienda to accept an expense as deductible, it must strictly meet three sacred requirements. If even one fails, the expense is considered non-deductible, and you could face an inspection and possible sanctions. It is crucial that you internalize these three golden rules that will guide all your expense management:

1. Link to economic activity: The expense must be directly and unambiguously related to your work. It must be necessary to obtain your income. Buying a computer for design is a linked expense; buying a console for your free time is not.
2. Documentary justification: You must be able to prove the expense with a complete and valid invoice. A simple receipt or bank statement is not always enough, especially for deducting IVA. The invoice must include all tax data, both yours and the supplier’s.
3. Accounting record: The expense must be correctly recorded in your accounting books. Specifically, in the expense and investment ledger. This record must be chronological and consistent with your activity.

The impact of these deductions is twofold and manifests in two key taxes: IRPF (Personal Income Tax) and IVA (Value Added Tax). For IRPF, expenses reduce your net income, which is the basis on which the tax payable in your annual declaration is calculated. Throughout the year, this is reflected in fractional payments (form 130). As for IVA, the IVA you bear on your purchases (input IVA) is subtracted from the IVA you charge on your sales (output IVA) in the quarterly settlement (form 303). If the input IVA is greater, you can request a refund.

Here’s a critical distinction: not all IRPF deductible expenses are IVA deductible, and vice versa. A classic example is civil liability or health insurance; these are deductible in IRPF as a business expense but do not carry IVA, so they do not affect your quarterly IVA settlement. Another case is travel expenses outside the European Union; an invoice from a hotel in New York can be a deductible expense in your IRPF if the trip is for business, but you will not be able to deduct any IVA because it is not governed by community regulations. Understanding this difference is vital for accurate accounting and for optimizing each tax separately.

The list of common deductions you can’t forget

Once the basic principles are understood, it’s time to delve into the list of the most common deductible expenses for the self-employed in 2026. These are the day-to-day expenses that, if managed correctly, represent the largest volume of tax savings. The first and most obvious group are operating expenses.

Operating expenses are, in essence, the raw material of your work. If you have an online store, they are the goods you buy to sell later. If you are a craftsman, it’s the wood, fabric, or materials you use. For a software developer, it could be code licenses or access to paid APIs. In general, it refers to any good you acquire to incorporate into your production process or the services you provide. The key here is that their cost is directly linked to each sale or project you undertake.

If you have employees, all associated costs are deductible. This includes salaries and wages, extra payments, severance payments, and, of course, the Social Security contributions you pay for them. But don’t forget that your own contributions also count. The self-employed contribution you pay monthly to Social Security is 100% deductible in your IRPF. With the real income contribution system fully in force in 2026, it is more important than ever to keep precise control of this expense. You can consult all the details in our guide on the new self-employed contribution 2026.

Rarely does a self-employed person work completely alone. It is very common to subcontract other professionals for specific tasks, and these costs are perfectly deductible. We are talking about services from independent professionals: the fees of your manager or tax advisor, the costs of a lawyer to draft a contract, the services of a notary, or the work of a freelance graphic designer you hire for a project. Provided they issue you a correct invoice with the corresponding IRPF withholding if applicable, you can deduct both the expense in your IRPF and the input IVA.

Finally, we cannot forget leases and royalties. The most common expense in this category is the rent for your workspace, whether it’s an office, a commercial premises, or a desk in a coworking space. But this section is much broader. This also includes vehicle leasing or renting for business use, machinery or equipment rental, and an increasingly relevant point: software licenses. The monthly or annual fees you pay for computer programs, cloud platforms, or online tools are fully deductible. Platforms like Frihet fall into this category, being a direct investment in the management and efficiency of your business.

Edge cases and complex expenses: What can I deduct as self-employed?

Beyond obvious expenses, there is a gray area where deductions become more complex and require impeccable justification. These are the expenses that Hacienda scrutinizes, and where a mistake can be costly. Mastering these edge cases will set you apart as a professional who manages their taxes expertly.

Vehicle and transport expenses are, perhaps, the biggest point of friction. Hacienda’s general rule is very strict: to deduct vehicle expenses (purchase, maintenance, fuel, insurance) in IRPF, you must prove exclusive use for the activity. This means the car is used solely and exclusively for work. This condition is easily met only by very specific professions such as taxi drivers, transporters, or commercial agents who use the vehicle as their main tool. For other self-employed individuals (an architect visiting construction sites, a consultant visiting clients), proving exclusive use is almost impossible, so the IRPF deduction is usually denied.

However, with IVA, the rule is slightly more flexible. The law allows deducting 50% of the input IVA on vehicle expenses, presuming mixed use (50% professional, 50% personal), as long as you can demonstrate a certain need for use in your activity. To exceed that 50% and aim for 100%, the burden of proof rests on you and is very demanding (vehicle signage, keeping it in a company garage outside working hours, not having another personal vehicle, etc.). As for other transport expenses such as taxis, VTCs, trains, or planes for work trips, they are 100% deductible as long as they are properly justified with a complete invoice and the purpose of the trip is clear.

Concept	IRPF Deduction	IVA Deduction	Key Requirement
Vehicle purchase and maintenance	100% if exclusive use (very difficult to prove)	50% by default (presumption of mixed use). 100% if exclusive use is proven.	Proof of exclusive use (travel log, signage, etc.)
Fuel	100% if exclusive use.	50% by default. 100% if exclusive use is proven.	Complete invoices (no tickets) and payment with company card.
Public transport (taxi, train, plane)	100%	100% (if applicable)	Complete invoice and justification of the professional reason for the trip.

Another battleground is the home allocated to the activity for those who work from home. You can deduct home expenses in proportion to the square meters you use for your business relative to the total. For example, if your office occupies 15 m² in a 100 m² house, you can deduct 15% of expenses such as IBI, community fees, or mortgage interest. But for utilities (electricity, water, gas, internet), the rule is different and more favorable since a few years ago. A 30% is applied to the proportion of the home allocated to the activity. Following the previous example, you could deduct 30% of 15% of your utility bills, i.e., 4.5% of the total bill. It’s a specific calculation that you must apply rigorously.

Per diems and representation expenses are also subject to strict limits. You can deduct subsistence expenses (meals) when you travel for work outside your usual municipality. The limit in 2026 within Spain is 26.67 € per day if there is no overnight stay, and 53.34 € if there is. Abroad, these figures rise to 48.08 € and 91.35 € respectively. To deduct them, it is essential to pay with an electronic means (card) and have a complete invoice from the establishment. Meals with clients or suppliers (representation expenses) are deductible with an annual limit of 1% of the net amount of your turnover.

Finally, training and subscriptions are deductible as long as they are directly related to your activity. A specialization course in digital marketing for a community manager is perfectly deductible. However, a master’s degree in art history for the same professional would not be. The same applies to subscriptions to professional magazines, databases, or publications; they must be linked to the sector in which you operate. The objective is to improve your professional skills, not your general culture.

Deductions in the digital age: Software, hardware, and online marketing

The business of a self-employed person in 2026 is inherently digital. We spend a significant part of our budget on online tools and services that are as essential as office rent. Fortunately, the vast majority of these digital expenses are 100% deductible, provided the justification requirements are met.

Software as a Service (SaaS) is the daily bread for any modern professional. We are talking about monthly or annual subscriptions to platforms that help you manage, create, or promote your business. This includes comprehensive management tools like an ERP with artificial intelligence, CRMs for client management, design platforms like Adobe Creative Cloud, cloud storage like Google Drive or Dropbox, and of course, your business management platform Frihet. As these are services used exclusively for the activity, their fee is 100% deductible. The main challenge is often obtaining a complete invoice, especially from foreign providers, but most serious platforms offer a billing panel for downloading it.

Hardware investments are also crucial. The purchase of a laptop, a mobile phone, a server, a printer, or monitors is a deductible expense. However, unlike a software subscription, these assets are not deducted all at once at the time of purchase (unless their value is very low). They are considered investment goods and their cost is deducted over several years through an accounting process called amortization. Hacienda publishes official amortization tables that establish the fiscal useful life of each type of asset. For example, computer equipment usually has a maximum linear depreciation coefficient of 25% per year, which means you deduct its cost over 4 years. This process more accurately reflects the wear and tear and loss of value of the asset over time.

Online marketing and advertising are the growth engine for many self-employed individuals. All expenses aimed at promoting your business are deductible. This covers a wide spectrum of services: pay-per-click campaigns on Google Ads or Meta Ads (Facebook, Instagram), hiring an SEO or SEM agency, the cost of email marketing tools like Mailchimp or ConvertKit, or subscribing to analytics platforms like SEMrush. Again, the key is justification. Make sure to set up your billing profile on these platforms as a company, with your NIF and tax address, so they issue correct invoices with itemized IVA (or with reverse charge if they are intra-community).

Common mistakes: Expenses Hacienda NEVER accepts

As important as knowing what you can deduct is having it crystal clear what expenses will never be accepted by the Tax Agency. Trying to deduct disallowed costs is one of the fastest ways to receive a notification from Hacienda, a parallel assessment, and a possible sanction. Avoiding these mistakes will save you money and a lot of headaches.

Firstly, any type of fine, penalty, or surcharge is a NON-DEDUCTIBLE EXPENSE. This includes traffic fines received during a work trip, penalties for late submission of your taxes (for example, IVA form 303) or enforcement surcharges issued by the Tax Agency itself. Hacienda’s logic is simple: a deductible expense must be necessary to obtain income, and penalties do not fulfill this function. They are the consequence of non-compliance, not a production cost.

Donations and gratuities also have no place in the deductible expenses of a self-employed person’s activity. A donation to an NGO, however laudable, is considered an act of personal generosity and not a business expense. While there are deductions for donations in the income tax declaration, these are applied to the general taxable base, outside the section on income from economic activities. This must be differentiated from representation expenses (meals with clients, low-value promotional gifts) which are deductible with a limit of 1% of turnover, as they are understood to have a commercial purpose.

Finally, the most common mistake is trying to deduct personal expenses without a clear and direct link to the activity. The list here is endless: weekly grocery shopping, clothes (with the exception of specific workwear with the company logo or individual protective equipment), cinema tickets, holiday expenses (even if you take your laptop), or meals you have alone. If you cannot defend to an inspector that this expense was strictly necessary for your business, do not include it. Mixing personal and professional finances is one of the 5 invoicing mistakes that cost you money and can raise suspicion.

How to justify and record your expenses to avoid problems

Knowing which expenses are deductible is only half the battle. The other half, equally important, is knowing how to justify and record them correctly so that they are impregnable against a possible Hacienda inspection. The burden of proof always falls on the self-employed person, so impeccable organization is not an option, it’s an obligation.

The pillar of justification is the complete invoice. For IVA deduction, it is an indispensable requirement in most cases. A simple ticket or simplified invoice is only valid for deducting IVA if the amount does not exceed €400 (IVA included) or in very specific sectors such as hospitality or transport, and even then it is always advisable to ask for a complete invoice. What should it contain? The complete tax details of the issuer and recipient (name, NIF, address), a correlative invoice number, the date of issue, a detailed description of the goods or services, the breakdown of the taxable base, the IVA rate applied, and the tax quota.

Alongside documentary justification, there is the accounting record. As a self-employed person, you are obliged to keep certain record books. The most important one for expenses is the Book of received invoices and investment goods. In it, you must record, chronologically and quarterly, all expense invoices related to your activity. Each entry must include the date, provider details, invoice number, taxable base, IVA type, and tax quota. Keeping this book up to date is not just a formal obligation; it is an essential tool to control your expenses as a freelancer and have a clear vision of your business’s profitability.

This manual process of collecting invoices, verifying data, and transcribing them into a record book is tedious and prone to errors. This is where technology becomes your best ally. Automation with Frihet completely transforms expense management. With a simple photo from your mobile, our optical character recognition (OCR) technology extracts all invoice data and automatically creates the accounting record. No more manual data entry.

Furthermore, Frihet connects to your bank accounts to perform automatic bank reconciliation. The platform cross-references your bank movements with the invoices and tickets you have uploaded, associating each expense with its corresponding payment. This system ensures that you don’t miss any deductions, that every expense is double-checked, and that your accounting is always updated and ready to file your taxes. Letting technology handle the heavy lifting frees up your time to focus on what really matters: growing your business. Discover more about automatic bank reconciliation in our 2026 guide.

Frequently Asked Questions

Can I deduct my home internet connection if I am self-employed?

Yes. If you work from home and have notified Hacienda of your home address as your place of work, you can deduct utility expenses such as internet. The general rule allows you to deduct the result of applying 30% to the existing proportion between the square meters of the home allocated to the activity relative to its total surface area, unless a higher use can be proven.

How are the expenses of a car I use for work and personal life deducted?

It’s complex. For IRPF, Hacienda requires exclusive use for the activity, which is very difficult for most self-employed individuals to demonstrate. However, for IVA, the law presumes 50% use for the activity, so you can deduct 50% of the IVA fees for purchase, fuel, and maintenance, as long as you need it for your work.

Do I need a separate bank account for my self-employed expenses?

It’s not a strict legal obligation, but it is extremely recommended. Having a bank account exclusively for your activity greatly simplifies accounting, facilitates bank reconciliation, and offers a much clearer and more professional image in the event of a possible Hacienda inspection. Avoid mixing personal and professional finances.

What happens if I lose an invoice for a deductible expense?

If you lose an invoice, you legally cannot deduct that expense, neither in IRPF nor in IVA. The first thing you should do is contact the provider and request a duplicate, which has the same legal validity as the original. Using tools like Frihet to digitize invoices the moment you receive them eliminates this risk.

How long should I keep my expense invoices?

You must keep invoices and all accounting documents for a minimum of 4 years, which is the general tax statute of limitations period in Spain. However, the Commercial Code establishes a period of 6 years. For security, and to cover yourself against any eventuality, it is recommended to keep all documentation for at least 6 years.
