TaxDown Free tier

What TaxDown actually does

TaxDown is a Madrid-based service built specifically around Spain's annual personal income tax return — the Renta declaration — combining an automated calculator with human tax-expert review.

The core product

The platform covers Spain's Renta declaration plus related filings such as self-employed (autónomo) returns, investment and cryptocurrency income reporting, and responses to notifications from the AEAT, Spain's tax agency. TaxDown reports more than 150 in-house tax professionals and over two million declarations processed to date, and it's backed by investors including Mediaset, Atresmedia, Base10 and the Spanish public investment fund Enisa across multiple funding rounds. Anyone can use the free calculator to get an estimated result before deciding whether to pay for anything — a genuinely useful way to see roughly where you stand before committing.

What's new or notable

TaxDown's current paid structure runs three named tiers rather than a single flat plan. PRO, starting at €35/year, covers calculation and optimisation, expert fiscal review, filing with the AEAT on the customer's behalf, help responding to AEAT notifications, and a 24-hour AI assistant with annual support responding within 24 hours. LIVE, from €45/year, adds real-time expert advisor access over chat and WhatsApp with priority responses in minutes, plus extra forms like Modelo 030 for address changes. FULL, from €65/year, goes further still with a personal advisor who handles the filing end-to-end, a review of the past four years of returns for missed deductions or errors, specialised support for complex situations like crypto, expat status or multiple properties, and additional administrative forms (Modelos 149, 151, 210). TaxDown is explicit that the final price depends on the complexity of an individual's tax situation and is always confirmed before payment, so the "from" prices are a starting point rather than a guaranteed final cost.

Who should use TaxDown

Great fit if…

• You want a straightforward Spanish tax return filed with expert review — PRO covers calculation, optimisation and AEAT filing for a modest starting price.
• You want fast human help during filing season — LIVE's WhatsApp and chat access with priority response times suits anyone who wants quick answers, not just an AI assistant.
• Your tax situation is genuinely complex — self-employment, crypto, expat status or multiple properties are exactly what FULL's specialised support and multi-year review are built for.

Skip it if…

• You don't pay Spanish taxes — TaxDown covers the Spanish system only; there's no equivalent product for any other country's tax authority.
• You want the whole thing free — the free tier only produces an estimate; filing, expert review, or help with a tax authority notice all require a paid plan.
• You need price certainty upfront — the exact cost depends on your situation's complexity and is only confirmed once TaxDown has assessed it.

Pricing in detail

All three paid tiers are priced "from" a starting point, with the final price confirmed before payment based on the complexity of the filing.

Where it falls short

• Spain-only coverage — TaxDown only handles the Spanish tax system, with no filing capability for any other country's tax authority; a separate, differently branded product exists for Mexico.
• Paid plan required to actually file — the free tier stops at an estimate; submitting a return, getting expert review, or getting help with a tax office notice all sit behind PRO, LIVE or FULL.
• Final price isn't fixed upfront — the price a given filer pays depends on how many income sources, investments or special situations their case involves, so the "from" prices aren't guaranteed final costs.

Privacy & data

Filing a tax return through TaxDown means sharing genuinely sensitive personal and financial data — income sources, investment details, and in some cases crypto holdings — with the platform, so it's worth knowing how that's handled. TaxDown is registered with Spain's AEAT as a Social Collaborator for filing purposes, which comes with its own regulatory data-handling obligations, and it is subject to GDPR as a Spain-based company. Its LIVE and FULL plans route advisor communication through WhatsApp, which means some support conversations pass through a third-party messaging platform rather than TaxDown's own app exclusively — worth being aware of if you'd rather keep tax discussions inside one system. Beyond that, TaxDown's public pricing pages don't detail specifics like its own encryption standards, so its own privacy policy is the place to check for more detail.

How we checked this

This review is based on TaxDown's official pricing page (taxdown.es/precios), checked on 2026-09-04, for tier names, starting prices and included features. We did not create an account or file a real return, so the exact final price for any specific tax situation should be confirmed directly with TaxDown before paying.
