Deductible expenses for freelancers 2026: Complete updated list

If you work as a freelancer in Spain, every euro you deduct reduces your taxable income for personal income tax (IRPF) and VAT. In 2026, tax authority criteria remain consistent: an expense is deductible if it is tied to your business activity, documented with an invoice, and recorded in your accounting books. Many freelancers miss thousands of euros annually by not deducting legitimate expenses like mobile connectivity for work travel, digital tools, or trips to clients.

At eSIM Ahora we wrote this guide because our freelancer clients travel constantly (developers attending conferences, designers meeting overseas clients, consultants at trade shows) and ask whether they can deduct their travel eSIM. Short answer: yes, if the trip is business-related and you keep the invoice. Long answer is in this complete list of deductible expenses for freelancers 2026, updated with current limits, concrete examples, and common pitfalls.

What makes an expense deductible

Tax authorities apply three filters simultaneously. If your expense passes all three, you deduct 100% (with limited exceptions covered later). If it fails even one, deduction is zero.

Filter 1: Connection to business activity. The expense must be necessary to generate income. A laptop for a graphic designer passes; a laptop for the designer's child does not. Tax authorities do not require the expense to be essential, only that it have an objective relationship to your work.

Filter 2: Complete invoice documentation. You need an invoice or receipt with your tax ID, detailed description, VAT itemized (where applicable), and issuer details. A grocery store receipt without your tax ID does not qualify. A simplified invoice (up to €400) works for VAT deduction, but tax authorities prefer full invoices in audits.

Filter 3: Accounting record. The expense must appear in your expense log with date, vendor, description, taxable amount, and VAT. Many freelancers save invoices in folders but never record them; in an audit, tax authorities reject those expenses even if you have the paper.

Mixed-use expenses (business + personal) are prorated. If you use your car 60% for work and 40% for personal use, you deduct 60% of fuel, insurance, and maintenance. Tax authorities accept reasonable criteria: business kilometers vs. total, days of use, floor space of office (if you work from home). What they reject is inventing a percentage without justification.

Setup and advisory costs

When you register as a freelancer, you pay registration fees, notary costs (if you establish an LLC), accounting firm charges for registration forms, and possibly a lawyer to review contracts. All 100% deductible.

Accounting and tax advisory fees. Deduct 100% of your monthly accounting firm cost. In 2026, Spanish accounting firms charge between €40 and €120/month depending on business complexity. If you invoice over €600,000 annually, fees rise to €150-€300/month due to additional accounting requirements.

Professional association dues. If you are an architect, lawyer, engineer, doctor, etc., your professional association fee is 100% deductible. Business associations (like trade chambers) also qualify. Recreational or political associations do not.

Training and courses. Deduct courses, master's programs, certifications, and conferences if related to your business. A digital marketing course for an ecommerce freelancer: deductible. A cooking course for a programmer unrelated to their work: not deductible. Tax authorities have rejected language courses in audits without documented professional use. Save the course syllabus and a paragraph explaining its relevance to your work.

Office space and utilities

If you rent an office, deduct 100% of rent, property tax, building fees, water, electricity, internet, and cleaning. If you work from home, prorate based on square footage.

Home office example. An 80 m² apartment with 12 m² of dedicated workspace = 15% business-related. Deduct 15% of rent (or depreciation if you own), property tax, building fees, home insurance, utilities, and internet. You cannot deduct 100% of electricity arguing you work all day; tax authorities use the floor-area method unless you provide technical proof.

Internet and landline phone. Deduct 100% if used only for work. If the line is mixed (work + streaming + personal calls), prorate. Standard practice: 50% if it is your only line, 100% if you have a separate business line.

Mobile phone and data during travel. Deduct your monthly plan if you use the phone for client calls, order management, or business social media. If you travel and purchase extra data (roaming or eSIM), 100% deductible if the trip is business-related. Many freelancers buy an eSIM in the range of $3–$8 for 3–10 GB to use at trade shows, supplier visits, or conferences; the invoice counts as a connectivity expense, the same as a Movistar or Vodafone plan. See plans for Spain.

Office supplies and equipment

Computers, tablets, printers, ergonomic chairs, desks, filing cabinets: 100% deductible if used only for work. If a laptop is shared for personal use, prorate (typical: 70%–80% business if you work 8 hours/day on it).

Depreciation vs. direct expense. Assets over €300 (VAT included) are depreciated over several years per tax authority schedules. A MacBook Pro at €2,500 depreciates over 4 years (technology equipment = 26% annually max). You can deduct 100% of VAT in the purchase year, but the cost is spread. Assets under €300 go to direct expense that year.

Software and subscriptions. Adobe Creative Cloud, Microsoft 365, Salesforce, Notion, Figma, hosting, domain names: 100% deductible. Annual subscriptions are expensed in the fiscal year even if you pay in January and coverage extends through December of the following year.

Vehicles and transportation

Car expenses are the most audited. Tax authorities know many freelancers deduct 100% of a vehicle used for weekend trips.

Passenger vehicles. If you purchase a car registered to your business, you deduct VAT and depreciation only if 100% professional. In practice, almost no one justifies this. Commercial agents and transporters do (driving IS their work). A designer visiting a client once weekly does not. Tax authorities allow you to deduct fuel, parking, and tolls for business trips if you maintain a mileage log (date, origin-destination, kilometers, client/event). Without a mileage log, tax authorities reject fuel expenses.

Commercial vehicles (vans). Deduct 100% of VAT on purchase, depreciation, fuel, insurance, vehicle inspection, and maintenance. Tax authorities do not dispute mixed use of a Mercedes Sprinter van; they assume it is business use.

Taxis, Uber, Cabify. 100% deductible if the trip is business-related. Request an invoice with your tax ID (not a simplified receipt). Transportation apps issue invoices automatically if you configure your freelancer profile.

Public transit. Deductible if you travel to see clients, suppliers, or events. A train ticket Madrid–Barcelona for a client meeting: deductible. A monthly metro pass with no documented business trips: tax authorities reject it. If you work from home and take the metro to visit clients, each individual ticket is deductible; the monthly pass is difficult to justify.

Travel, hotels, and meals

Business travel is deductible if you demonstrate professional purpose: trade show, client visit, training, business development.

Flight, train, and bus tickets. 100% deductible. Keep the ticket + proof of the activity (show ticket, client email, conference program). Tax authorities accept a Barcelona–Berlin flight if you attend a sector conference; they reject a Cancún flight with no justification.

Hotels. 100% of lodging is deductible. You do not deduct the minibar, spa, or pay-per-view movies. The invoice must detail what you bought; if it says "lodging + extras," tax authorities may demand a breakdown.

Meal allowances. Tax authorities allow deduction of meal expenses during travel without an invoice up to €26.67/day in Spain and €48.08/day outside Spain (2026 amounts per Royal Decree 439/2007). If you spend €30 on dinner in Paris, deduct €30 with an invoice; without one, only €48.08. Most freelancers combine multiple meals on the hotel invoice to avoid loose receipts.

eSIM and roaming on business travel. If you travel to Mexico for a trade show, buy an eSIM in the range of $3–$8 for 3–10 GB, and use the data to coordinate with suppliers, handle urgent emails, or post on business social media, the expense is 100% deductible. We issue an automatic invoice with your tax ID after each purchase; it goes into your accounting as "telecommunications services" or "travel expenses." Many digital freelancers (programmers, designers, consultants) work from anywhere; if you spend 15 days in Thailand working for Spanish clients, the eSIM is as deductible as coworking or the café where you sit. See plans for Mexico or Thailand.

Marketing and advertising

Everything you invest to attract clients is 100% deductible.

Google Ads, Facebook Ads, LinkedIn Ads. Deductible. Keep invoices from Google Ireland Ltd. or Meta Platforms Ireland (typical issuers for Spanish accounts). VAT on digital services from EU companies is self-assessed on your quarterly VAT return (reverse charge).

Graphic design, web, and photography. Deduct logos, packaging design, product photo shoots, web development, and maintenance. If you pay a freelancer, request an invoice with 15% IRPF withholding (2026 rate for professionals; 7% for first two years). You report that withholding on your quarterly IRPF form.

Trade shows and events. Booth cost, brochure printing, material transport, booth staff, catering: deductible. Networking dinners with potential clients fall under meal allowances (the €26.67/day limit applies only without invoices; with a named invoice, the full amount counts).

Gifts to clients. Deductible up to €300 per client per year (article 14.1.e of the IRPF Law). If you give 10 bottles of wine at €40 each to 10 different clients: yes. If you give a €1,000 iPhone to one client, you deduct only €300.

Insurance

Deduct insurance that protects your business.

Professional liability insurance. Mandatory in many professions (architects, lawyers, doctors). 100% deductible.

Private health insurance. Deductible up to €500/year for you as the business owner, €500/year for your spouse, and €500/year for each child under 25 (max €2,500 total with spouse and 3 children). Tax authorities raised the cap from €500 to €1,500 for freelancers with no employees under the Startup Law (Law 28/2022), but only if you invoice under €600,000 and have no employees. In 2026, most small freelancers deduct up to €1,500 if solo; those with employees or higher revenue deduct up to €500.

Life and accident insurance. Deductible if it covers professional contingencies (disability, work-related accident). Pure life insurance (beneficiary: family) is not deductible.

Credit insurance. If you sell to companies with deferred payment and buy credit insurance, 100% deductible.

Financial and banking costs

Interest on loans to finance business (equipment, commercial vehicle, office renovation) is deductible. Interest on personal loans unrelated to your business is not.

Bank fees. Deduct business account maintenance, transfer fees, and POS fees. If you use a mixed account (business + personal), prorate by volume of business transactions.

Credit card interest. Deductible if you finance business expenses. Hard to justify in audit; tax authorities prefer dedicated financing (loan, lease).

Salaries and Social Security

If you hire employees, deduct 100% of gross salaries, Social Security contributions, and severance. You must file IRPF withholding forms and Social Security forms on time; tax authorities cross-check the data in audits.

Your own freelancer contribution. NOT deductible for personal income tax (tax authorities consider it a personal social contribution, not a business expense). It does reduce your quarterly estimated tax payment (Form 131) if you use direct estimation method. In practice: your freelancer contribution does not lower your annual tax base, but it does reduce quarterly payments.

Supplies and consumables

Consumable materials: paper, toner, USB drives, cables, batteries, office cleaning products, coffee and water for the office (if you receive clients or have employees). 100% deductible.

Tax authorities reject household expenses disguised as business. A solo freelancer deducting €200/month for coffee is suspicious; €20/month is reasonable.

Comparison: eSIM Ahora vs competitors on deductible expenses

At eSIM Ahora we charge a range of $3–$8 for 3–10 GB in most European destinations (Spain, France, Italy, Germany); Holafly charges $19 for 5 days with unlimited data but throttling after 5–10 GB depending on country (as of May 2026). Airalo charges between $5 and $15 for 3–7 GB in Europe, similar to us. The difference for freelancers: all of us issue invoices with itemized VAT, so deductibility is identical. What varies is total cost: if you travel 6 times yearly to European trade shows, Holafly costs $114 USD (≈€104 at May 2026 rates); with eSIM Ahora, between €18 and €48 depending on actual use. For tax purposes, it makes no difference; for cash flow, the savings are €60–€80 you can invest in another deductible expense.

Common errors tax authorities reject in audits

Error 1: deducting 100% of your car without a mileage log. Tax authorities reject fuel, parking, and tolls unless you prove which trips were business. Keep a spreadsheet or app with date, origin-destination, kilometers, and client. No log = zero deduction.

Error 2: mixing personal expenses. The grocery store receipt where you buy office supplies + milk + cereal is not fully deductible. Request separate invoices or buy office supplies at specialty stores.

Error 3: invoices in someone else's name. If your spouse buys a laptop for your business but the invoice is in their name, you do not deduct it. Tax authorities require the invoice tax ID to match your business.

Error 4: not recording expenses in your accounting books. You save the eSIM invoice in a folder but never enter it in your expense log. In audit, tax authorities only accept recorded expenses.

Error 5: made-up proration percentages. "I deduct 90% of my phone because I work a lot" with no justification. Tax authorities accept objective criteria: business vs. total calls (if you have records), hours of use (if you have metrics), or a reasonable percentage (50%–70% for a single line). 90% with no proof: rejected.

Limits and exceptions 2026

FAQ

Can I deduct an eSIM for a business trip abroad?

Yes, 100% if the trip is business-related (trade show, client, business development, training). We issue an invoice with your tax ID; it goes into accounting as a telecommunications expense. If you travel to Japan for a tech conference, an eSIM in the range of $3–$8 for 3–10 GB is as deductible as your flight or hotel. Keep the invoice + proof of the event (ticket, program, confirmation email). See plans for Japan.

What if I use my phone for work and personal use?

Prorate. If it is your only line, the standard is 50% business, 50% personal. If you have two lines (one business, one personal), deduct 100% of the business line. Tax authorities accept reasonable percentages; they reject 100% on mixed lines unless you prove exclusive business use (call records, two operator invoices).

Are weekend travel expenses deductible?

Yes, if you travel on weekends for business reasons (the show is Saturday–Sunday, the cheapest flight leaves Friday, etc.). Tax authorities look at purpose, not the calendar. A Madrid–Munich flight Friday night + hotel Friday–Sunday + return Sunday night to attend a Saturday–Sunday trade show is 100% deductible.

How long must I keep invoices?

Tax authorities can audit the past 4 years (5 if there are fraud indicators). Keep invoices and accounting records a minimum of 6 years (practical recommendation: 7 years to cover the full statute of limitations from the fiscal year end).
