TaxDown lets people prepare and submit Spanish income tax returns online from a phone or computer. It is available on Android, iOS, and web, and can import tax details using Cl@ve PIN, a digital certificate, or a reference number. Its Rita engine selects applicable questions and checks more than 250 deductions and allowances; an expert reviews each return before submission. The service covers employment income, self-employment, rental income, investments, and tax notices. For rentals, it calculates income and expenses and identifies deductible costs and exemptions; for investments, it calculates gains and losses and integrates investment platforms. The Free plan calculates a result but does not include expert review or filing. PRO costs €35 a year and includes one return, expert review, filing, and basic support. LIVE costs €45 a year and adds advisers by chat or WhatsApp; FULL costs €65 a year and adds a personal adviser and review of the last four returns. FULL is unavailable under the regional tax regime and excludes traceability and second residence-procedure filings.
