Skip to content Full accounting and tax support for companies and sole traders in Spain: from registering the business with the tax and social security authorities to day-to-day bookkeeping, reporting and tax planning. We work with both local companies and foreign structures setting up in Spain, in Russian, Ukrainian, Spanish and Catalan. Our team combines accountants, tax advisors and lawyers, so bookkeeping is handled in coordination with the company's legal and tax support, not in isolation.
We register the new company or sole trader with the Agencia Tributaria (obtaining a CIF/NIF), the General Treasury of Social Security, and, where relevant, regional and municipal bodies. We select the correct economic activity codes (epígrafes IAE), file the initial activity declarations (modelo 036/037), and advise on the most suitable tax regime.
Why us: we choose activity codes and the tax regime with future optimisation in mind, not just formal compliance.
We register the company with the Spanish Chamber of Commerce and, where needed, with the Commercial Registry (Registro Mercantil): drafting the bylaws, recording the details of founders and directors, and obtaining the certificates and extracts required to open a bank account, take part in tenders, or carry out foreign trade activity.
Why us: we handle the registration so the data matches across the tax, commercial and banking registries — avoiding mismatches that later block a bank account or a tax filing.
We manage staff registration: registering employees with Social Security on hiring (alta) and deregistering them on termination (baja), drafting employment contracts, calculating and filing social security contributions, managing sick leave, holidays and bonuses, and supporting labour inspections.
Why us: we run payroll in coordination with the company's accounting and tax filings, so payroll figures and tax returns never diverge.
We handle the company's day-to-day bookkeeping: processing invoices, delivery notes and bank statements, tracking income and expenses, maintaining the accounting books (Libro Diario, Libro Mayor), and preparing the data for subsequent tax and financial reporting. We work with both paper and electronic document flows.
Why us: we close the books every month, not once a quarter, so the data is already reconciled and ready by the time returns are due.
We carry out a tax audit of the company: checking the correct calculation and payment of taxes (VAT, corporate tax, IRPF, IAE), identifying risks of reassessments and penalties from the tax authority, reviewing whether accounting policy complies with current legislation, and preparing recommendations to fix any issues found before a tax inspection.
Why us: we audit preventively, before the inspector's visit, not after a request from the tax office arrives.
We prepare and file the company's tax and accounting reports: quarterly and annual VAT returns, corporate income tax (Impuesto de Sociedades), IRPF withholding returns, and the Annual Accounts (Cuentas Anuales) for the Commercial Registry. We keep to filing deadlines and track regulatory changes.
Why us: we keep a filing calendar for every client and submit returns ahead of time, with no late-filing penalties.
We take on full management of the company's financial and tax reporting — from day-to-day bookkeeping through to consolidated reporting for owners and investors: monthly management reports (P&L, cash flow), monitoring of receivables and payables, and coordination with external auditors where needed.
Why us: owners get more than formal tax reporting — a management-level view of where the company's money is actually going.
We handle bookkeeping for sole traders (autónomos): tracking income and expenses, calculating and filing quarterly and annual IRPF and VAT returns, optimising the taxable base through correct recording of deductible expenses, and advising on the switch from autónomo to an S.L. as turnover grows.
Why us: we work out when switching to an S.L. actually pays off, and support that transition — not just day-to-day bookkeeping.
We analyse the company's financial and business performance: revenue and expense trends, profitability by business line, cost structure, and liquidity and debt indicators. We produce a report with concrete recommendations on where the company is losing margin and how to restructure costs or its tax position.
Why us: the analysis is produced by the same team that keeps the company's books, so the recommendations rest on real data, not a one-off extract.
We advise on taxation and lawful tax optimisation: choosing the right legal form and tax regime, structuring transactions and corporate groups, applying double-taxation treaties, and planning major transactions (selling a business, selling property, distributing dividends) with their tax consequences in mind.
Why us: advice comes from a registered tax advisor (no. 8772) — recommendations hold up under a subsequent tax inspection.
