How to Deduct Your Phone in Simplified Direct Estimation — 2026 Guide

If you work as a self-employed professional under Simplified Direct Estimation (Estimación Directa Simplificada) in Spain, you can deduct phone expenses in your quarterly VAT filing and annual income tax return. However, Hacienda requires you to justify the professional use of the device and document every dollar. At eSIM Ahora we use eSIM to separate work and personal lines on a single phone, which simplifies tax traceability. This guide explains step-by-step how to deduct your phone without mistakes, what documents you need, and how to calculate the professional ratio.

What phone expenses you can deduct

Under Simplified Direct Estimation, you can deduct the following phone-related expenses:

• Monthly carrier plan (Movistar, Vodafone, Orange, travel eSIM plans like ours).
• Phone purchase (iPhone, Samsung, Xiaomi, etc.) if used for work.
• Professional accessories (headphones with microphone for calls, power bank for travel, car charger).
• Repairs (cracked screen, battery replacement, charging port replacement).

You cannot deduct:

• Personal expenses (entertainment apps, Spotify subscriptions, video games).
• Traffic fines related to phone use.
• Corporate gifts that include phones (unless they are for salaried employees).

The key is demonstrating that the expense serves an exclusive or primarily professional purpose. If you use the same phone for work and personal life, you must calculate a reasonable ratio (explained below).

Tax requirements for deducting your phone

Hacienda applies three criteria to accept the deduction:

1. Connection to your activity. The phone must be used to generate income: calls with clients, WhatsApp Business, corporate email, management apps (Stripe, Holded, Factorial).
2. Invoice under your name or tax ID. The carrier invoice or phone purchase must be in the name of your business activity (tax ID). If you have a Movistar account under your personal name, you must change the ownership to your tax ID.
3. Traceable payment methods. Pay by bank card or transfer. Cash payments above €1,000 between businesses and self-employed professionals have been prohibited since 2021 (Law 11/2021).

If you fail to meet these three requirements, Hacienda may reject the deduction during an audit and recalculate your taxable base.

How to justify professional use

The biggest mistake self-employed workers make is deducting 100% of the phone without justifying use. Hacienda accepts two approaches:

Exclusive use (100% deduction)

If you have a phone dedicated solely to your professional activity, you can deduct 100% of the plan and phone cost. Requirements:

• A separate number from your personal line.
• Registered under your tax ID.
• No personal apps (social media, games, personal banking).
• Call and message history exclusively professional (you can screenshot call logs each quarter as evidence).

At eSIM Ahora, many self-employed professionals use an eSIM for their work line and a physical SIM for their personal line. This allows you to deduct 100% of the eSIM plan without mixing expenses. For example, if you travel in Europe and buy a data plan for Spain with 10 GB for $8–$14 per month, that expense is 100% deductible if you use it only for work calls.

Mixed use (proportional deduction)

If you use the same phone for work and personal life, you must calculate a reasonable ratio. Hacienda does not have an official formula, but accepts these methods:

• Hourly ratio. If you work 8 hours per day (full-time), professional use is roughly 33% (8 hours / 24 hours). If you work 6 hours, roughly 25%.
• Call ratio. Download your call history from your carrier (Movistar, Vodafone, Orange typically offer monthly PDFs). Count professional calls vs. personal calls. If 70 of 100 calls are with clients, deduct 70%.
• Data ratio. If you use data-heavy work apps (Google Meet, Zoom, mobile CRM), you can estimate that 60–80% of data traffic is professional. Use tools like "Settings > Mobile Data > Data Usage by App" on iPhone or Android to generate a monthly report.

Keep documentation of your calculation. In an audit, Hacienda may ask you to justify your chosen ratio.

Deducting the phone's cost

A phone (iPhone, Samsung Galaxy, etc.) is a fixed asset if it costs more than €300 (VAT excluded). You have two options:

Straight-line depreciation (most common)

You spread the phone's cost across its useful life. The General Accounting Plan indicates 5 years for IT equipment, but Hacienda accepts 2–3 years for phones (rapid obsolescence). Example:

• You buy an iPhone 15 for €1,200 (€1,452 with VAT).
• You decide to depreciate it over 3 years (36 months).
• Monthly deduction: €1,200 / 36 = €33.33/month.
• Annual deduction: €400.

If you use it 100% for work, you deduct €400/year. If you use it 60%, you deduct €240/year.

Current expense (if under €300)

If you buy a mid-range phone for €250, you can deduct it as a current expense in the quarter of purchase (no depreciation needed). Enter the expense in box 305 of form 303 (deductible VAT) and in your income tax return as a business expense in the relevant category.

VAT deduction

The VAT on your phone plan and phone purchase is deductible in the quarter you pay it, provided you have the invoice in your name. Example:

• You pay €50/month for Vodafone (€60.50 with VAT). VAT is €10.50/month.
• In form 303 for the quarter (boxes 28–29), you reduce VAT by €31.50 (€10.50 × 3 months).

If you use the phone 70% for work, you can only deduct 70% of the VAT: €31.50 × 0.70 = €22.05. Note the ratio in your accounting records.

Tip: international data eSIM plans typically do not include Spanish VAT if purchased outside the EU or under traveler status. If you are a self-employed professional in Spain and buy an eSIM plan for travel to Japan or the USA, check your invoice to see if VAT is itemized. If not, you cannot deduct VAT (but you can still deduct the expense itself in your income tax return).

Common mistakes Hacienda penalizes

Mistake 1: Deducting 100% without justification

Many self-employed professionals deduct 100% of their plan without owning an exclusive phone. In an audit, Hacienda may recalculate at 30–50% (standard estimate) and charge the difference with a 15% penalty plus interest.

Solution: use the call-ratio or hourly method. Keep call history and an Excel spreadsheet explaining your calculation.

Mistake 2: Invoice under your personal name

If your Vodafone invoice is under your personal name (ID number), you cannot deduct the expense. Hacienda requires the invoice to be under your tax ID.

Solution: call the carrier and change the invoice owner to your tax ID. Vodafone, Movistar, and Orange do this within 48 hours at no cost. If you use our eSIM service, make sure to enter your tax ID in the "Business Name" field when purchasing (generates an invoice automatically with your tax ID).

Mistake 3: Cash payment

Paying for your phone in cash at a retail store may prevent deduction if there is no traceability. Additionally, cash payments above €1,000 between professionals have been illegal since 2021.

Solution: always pay by card or transfer. Keep your bank statement together with the invoice.

Mistake 4: Deducting entertainment expenses

If you pay for Netflix, Spotify, or Apple Arcade with the same card as your professional phone, Hacienda may question your usage ratio. Do not mix personal subscriptions with professional phone accounting.

Solution: use a separate bank card for personal expenses. Or document that Netflix is for professional development (streaming courses, industry documentaries) — but Hacienda rarely accepts this.

Comparison: eSIM Ahora vs. traditional carriers for self-employed professionals

For self-employed professionals who travel frequently (consultants, photographers, sales reps), roaming rates from Movistar, Vodafone, and Orange can be expensive. eSIM Ahora offers data plans in over 190 countries with invoices under your tax ID, which simplifies tax deduction.

At eSIM Ahora we charge rates in the $3–$8 range for 3 GB in short-stay destinations (Morocco, Turkey, Thailand), up to $8–$20 for 10–20 GB in long-stay destinations (USA, Canada, Japan). Unlike Holafly, which charges a flat $19 for 5 days with FUP throttling at 5 GB, we offer plans with no throttling and automatic tax invoices.

If you need global coverage without swapping your physical SIM, eSIM plans are deductible exactly like traditional plans: you need an invoice under your tax ID, must prove professional use, and calculate your ratio if you also use it personally.

Case study: self-employed graphic designer with mixed use

Profile: freelance graphic designer in Barcelona, invoices €3,000/month, uses iPhone 14 for client calls, WhatsApp Business, email, and personal social media.

Monthly expenses:

• Vodafone plan: €40/month (€48.40 with VAT).
• Bought iPhone 14 in January 2026 for €1,000 (€1,210 with VAT).

Deduction calculation:

• Estimated professional use: 60% (based on call history — 60 of 100 calls are with clients).
• Monthly deductible plan: €40 × 0.60 = €24/month.
• Monthly deductible VAT: €8.40 × 0.60 = €5.04/month.
• iPhone depreciation: €1,000 / 36 months = €27.78/month → deductible at 60% = €16.67/month.

Total annual deduction:

• Plan: €24 × 12 = €288.
• iPhone: €16.67 × 12 = €200.
• VAT: €5.04 × 12 = €60.48 (subtracted in quarterly form 303).

Documentation kept:

• Monthly Vodafone invoice (PDF from account portal).
• iPhone purchase invoice (Apple Store, under tax ID).
• Quarterly call history (phone screenshot).
• Excel spreadsheet with 60% calculation (columns: date, phone number, contact type — client/personal).

Alternatives: company card vs. self-employed expense

If you own an LLC (Sociedad Limitada) instead of being self-employed, you can pay for your phone with the company card and deduct 100% without calculating personal ratio, provided:

• The phone is registered under the company (company tax ID).
• Only administrators or employees use it for business purposes.
• You do not use it intensively for personal reasons (Hacienda may classify this as in-kind compensation and add it to your personal income tax base).

For self-employed professionals under Simplified Direct Estimation, there is no category for "company phone" — all expenses are attributed to your personal activity, and you must justify the ratio.

Accounting entry: where to record the expense

In your expense log (Excel, Holded, Sage, Contasimple), enter your phone under code 626 of the General Accounting Plan (Banking services and similar) or 629 (Other services). There is no specific code for "mobile telephones," so most accounting firms classify it as "Supplies" (628) or "Independent professional services" (623).

In your quarterly VAT return (form 303), enter:

• Boxes 28–29: VAT on current acquisitions (monthly plan).
• Boxes 30–31: VAT on investment goods (phone purchase, if over €300).

In your annual income tax return (form 100), enter:

• Boxes 108–109: Deductible business expenses (includes phone plan + phone depreciation).

FAQ

Can I deduct my phone if I work from home?

Yes. Working from home does not prevent you from deducting your phone, provided you use it for business (calls with clients, work apps). Home office deduction is separate from phone deduction — you can deduct both.

What if Hacienda rejects my 70% ratio during an audit?

In an audit, Hacienda may propose a lower ratio (for example, 50%) if they think your justification is weak. You would then recalculate at 50% and pay the difference with a 15% penalty plus interest. To avoid this, keep call history and a document explaining your calculation.

Do data plans with invoices under my tax ID include Spanish VAT?

It depends on the country of purchase. If you buy from Spain (Spanish IP), the invoice includes 21% VAT. If you buy from outside the EU, VAT may not apply (reverse-charge regime). Check your invoice for the VAT breakdown. If there is no VAT, you can deduct the expense in your income tax return but not the VAT in form 303.
