Cross-Border Tax Intelligence
Forensix reads every receipt line by line and tags each item as deductible — or not — under both HMRC and Hacienda rules. You hand your gestor a filing-ready evidence pack instead of a shoebox of tickets.
Drag to your income for the UK side. The Spanish side — IRPF, Autónomo social security, your cross-border net — is what Forensix maps for you, free.
Estimate for a 2025/26 employee. Self-employed, regional and cross-border figures are free after sign-up. Always confirm with a gestor.
If you operate as a UK Sole Trader or Ltd Company while living in Spain (Autónomo), your tax liability spans two jurisdictions. Traditional apps only catalog expenses in a single currency and code under a single country. Forensix implements the dual-ledger bridge.
UK allows deduction of business expenses incurred "wholly and exclusively" for trade. Pre-commencement expenses are deductible up to 7 years. Capital allowances (AIA) let you write off 100% of tech assets in year one.
Spain (Agencia Tributaria) requires formal invoices (Factura Completa) with your NIF/NIE. Travel must be strictly documented. Groceries are disallowed. Representación (client food) is capped at 1% of turnover.
We handle the reconciliation dynamically. We track if an invoice meets Spanish NIF requirements and flag potential liabilities, while keeping standard HMRC deductions separate. Your accountant gets clean, compliant ledger sheets.
Upload up to 15 receipts at once. No waiting in line for individual scans to complete. Our parallel processing engine performs OCR text recognition, parses vendors, currencies (GBP, EUR, USD), dates, total values, and extracts tax IDs (NIF) instantly.
We don't just dump a flat 50€ expense for a supermarket run. Our AI parses receipts item-by-item. It segregates personal groceries from client representation meals and flags single-item deductibility parameters. Perfect for proving expenses to Spanish tax inspectors.
Query your overall business finances in plain English or Spanish. Learn if buying a new camera is deductible, calculate your effective Spanish Autónomo social contributions, or project your UK corporate tax. Toggle between a standard clean interface and a hard-boiled "Detective Noir Theme".
"The rain is pounding Madrid tonight. I looked at your numbers. Mercadona files look clean, but you're drowning in Starbucks vice spend. Let's dig in."
Export a clear Gestor Pack when it is time to file: your transactions grouped by category, NIF-matched where possible, with GBP and EUR conversions and the figures your accountant actually needs. Less back-and-forth, faster filing.

Under the UK-Spain Double Taxation Treaty, if you are a Spanish tax resident (present 183+ days in a calendar year), you are liable to pay tax in Spain on your worldwide income. If you invoice via a UK Ltd company, you pay UK Corporation Tax, but may owe personal tax and Autónomo social contributions in Spain. Forensix segregates expenses in both ledgers so your accountants in both countries can coordinate correctly.
Spanish accountants (Gestores) require very strict reporting. If you upload plain receipts, they will refuse to deduct them unless they display the vendor NIF (tax identification) and your personal NIF/NIE. The Gestor Pack exports a clean PDF statement grouped by category with NIF codes matched and validated, saving hours of review.
You drag and drop up to 15 PDFs or image files. They are processed in parallel using the Gemini multimodal JSON extraction API, which maps out vendor, NIF, date, total amount, taxes, currency, and parses itemized receipt lines.
