Why we specialise in your profile

Our staff understand the reality of developers, designers and technology consultants first-hand because part of our team comes from the tech sector. We understand how you work: clients in the USA and UK, remote engagements, payments in dollars and the need for a tax adviser who speaks your technical language.

20% of our clients in this profile invoice up to €20,000 a year, 70% invoice between €20,000 and €60,000, and the remaining 10% exceed €60,000. We know the Spanish tax challenges at each level and adapt the strategy to your actual turnover.

Mini FAQ for technology and strategy consultants

Consultants and developers invoicing only a few companies have a simpler Spanish tax structure: one IAE activity code, recurring invoices and few suppliers. This enables an efficient service at €25.90/month without compromising quality.

Developers, software engineers, IT consultants, DevOps professionals, data engineers, web and UX designers, strategy and management consultants, business analysts, freelance project managers, financial consultants and any specialist with one IAE activity code invoicing one or a few companies.

Yes, if you invoice businesses in the EU. We handle ROI registration at no extra cost and file Modelo 349 quarterly. You do not need ROI registration if you invoice outside the EU.

Yes. Assets costing more than €300 are depreciated over their useful life, normally four years for computer equipment. You deduct the full VAT in the purchase quarter, and the depreciation expense reduces your personal income tax each year.

If you invoice a Spanish company and carry out a professional activity, you normally apply 15% personal income tax withholding, or 7% during the first two years. You do not apply Spanish withholding when invoicing a foreign company. We confirm the exact rate.

We record the ECB exchange rate on the invoice date. If it differs when you receive payment, we document the positive or negative exchange difference so you are taxed only on the amount actually received in euros.

Yes, with no penalty. If you diversify clients, you can move to BASIC (€29.90); if you hire employees, to PLUS (€47.90); or if you open new business lines, to MAS (€60.90). We close the current quarter before moving your account.

Yes, at no extra cost. We select the most suitable IAE activity code, file forms 036/037, register you with Social Security under RETA and review incentives such as the reduced initial contribution.
