Companies operating in Spain must keep accounting records in accordance with the Commercial Code and the General Accounting Plan, with accounting obligations covering recording, preparation and presentation of financial information.
Commercial companies must keep, legalise and maintain at least a Journal and an Inventory Book and Annual Accounts; entries must be recorded day by day or in grouped totals of periods not exceeding a quarter, and books must be legalised at the Mercantile Registry within four months after financial year end.
Directors must prepare annual accounts within three months after year end, the general meeting must approve them within six months and accounts must be filed with the Mercantile Registry within the month following approval, with failure to file leading to registry closure and potential fines.
Accounting books and documents must generally be retained for six years from the date of the last entry of the financial year; tax law has a four-year limitation period, but practical guidance often recommends retention of ten years to cover overlapping obligations and potential claims.
The purpose of Spanish bookkeeping is to provide reliable financial statements and tax records, enable the Mercantile Registry and tax authorities to verify compliance and support management and creditor decisions.
Properly maintained Spanish accounting books and annual accounts, legalised and filed as required, with accounting and tax documents retained for at least six years and often up to ten years.
