TaxDown

What TaxDown does

TaxDown helps individuals and self-employed people prepare and submit Spain’s income tax return from a phone or computer. It also covers rental and investment income, deductions, tax notices and other listed filings.

Its system imports tax details using Cl@ve PIN, a digital certificate or a reference number. TaxDown says its experts review each return before submission and that it has handled more than two million returns.

Fees and plans

The Free plan calculates the return and shows the result. Calculation is free and does not require a card, but expert review and filing need a paid plan.

PRO costs €35 a year and includes one return, calculation, optimization, expert review, filing, covered notices and support within 24 hours. LIVE costs €45 a year and adds chat or WhatsApp advisers with faster replies. FULL costs €65 a year and adds a personal adviser, review of the last four returns, and models 149, 151 and 210. FULL excludes traceability, second residence procedures and the foral tax regime.

For self-employed users, STANDARD costs €2990 a month with a minimum three-month term. It includes autónomo registration, quarterly income-tax and VAT filings, an income-tax return, a 24-hour AI assistant and chat support within 24 hours. PREMIUM costs €5990 a month with the same minimum term and adds a personal manager, priority WhatsApp, tax-authority notices and tax planning.

Subscriptions bought from March 15 through December 31 renew between February and March. Cancellation is available on the website, with access continuing to the end of the billing cycle. TaxDown accepts major cards, Google Pay and Apple Pay.

Where it runs

TaxDown runs on the web and has apps in Apple’s App Store and Google Play. The service supports Android and iPhone, and the return can be prepared and filed from a phone or computer.

Protection and rules, as TaxDown publishes them

TaxDown says it is a Social Collaborator of Spain’s tax agency, AEAT. It says connections with Hacienda use Cl@ve, data is encrypted, and nothing is filed without confirmation.

The company states that it uses data encryption, firewalls, Amazon Web Services security and an integration with the tax agency. It says it does not sell or share data and uses it only for the return. Sign-in methods match those used by Hacienda, including Cl@ve PIN, a digital certificate, a reference or the prior year’s tax box.

Strengths

A free calculation lets a reader see a result before paying. Paid individual plans include expert review and filing, while higher plans add human advisers.

TaxDown says its engine checks more than 250 deductions and benefits. It also calculates rental income and expenses, identifies deductible costs and exemptions, and handles investment gains and losses.

Catches

The free tier does not include expert review or filing. Individual subscriptions renew in the February-to-March period described above, and cancellation does not end access until the cycle finishes.

FULL is not available for the foral tax regime and does not include traceability or second residence procedures. The self-employed plans require at least three months, so the monthly prices do not describe a one-month commitment.

Who may want another service

TaxDown may not fit someone who needs the foral regime, traceability or a second residence procedure under FULL, or who wants filing without a paid plan.

Verdict

TaxDown suits Spanish residents and self-employed users who want online preparation, a free calculation and optional expert involvement. Its individual tiers set clear annual prices, while LIVE and FULL add human contact. The autónomo tiers bundle recurring filings and support but require a three-month minimum. Readers with foral-tax needs or excluded residence procedures should check the stated limits before choosing a plan.
