As the end of the fiscal year approaches, international companies operating in Spain must ensure that their accounting, tax, and corporate obligations are fully up to date. Beyond a legal requirement, year-end compliance is a strategic opportunity to review performance, optimize future planning, and safeguard the company’s financial reputation. This legal checklist highlights the key obligations that every company with operations in Spain should complete before closing the fiscal year — helping you avoid last-minute stress, administrative delays, or potential fines.
1. Close the Accounting Year
The year-end closing marks the starting point for all subsequent accounting and tax processes. In the legal checklist we must include this.
- Companies must record all income, expenses, provisions, and adjustments for the financial year, ensuring accurate and transparent bookkeeping.
- The closing date is typically 31 December, unless a different fiscal year has been adopted.
- The accounts must comply with the Spanish General Accounting Plan (PGC) or the PGC for SMEs, depending on company size.
Proper closing ensures a reliable financial picture and prepares the ground for the preparation and audit of annual accounts.
2. Preparation and Approval of Annual Accounts
The management body (whether a sole director, joint directors, or board of directors) is responsible for preparing and signing the company’s annual accounts.
- Deadline: within three months after year-end (i.e., by 31 March if the year ends on 31 December).
- All directors must sign and date the accounts.
- Failure to do so can result in corporate liability and administrative penalties.
Once prepared, the annual accounts must be approved by the General Shareholders’ Meeting within six months of year-end.
3. Legalization of Mandatory Books
Within four months after the fiscal year ends (by 30 April for most companies), all mandatory books must be legalized electronically before the Mercantile Registry corresponding to the company’s registered office. In the legal checklist we must include this.
These include:
- General ledger and inventory book
- Minutes book
- Annual accounts book
Legalization certifies that the books have not been altered afterward and protects directors and shareholders from potential liability. Late submission, however, can be interpreted as a lack of diligence. So, in the legal checklist we must include this.
4. Plan and Review Tax Filings
A proactive tax review before year-end is crucial to ensure compliance and avoid errors. Key filings include:
Quarterly returns (Modelo 111, 115, 303, 130/131):
- Employee and professional withholdings
- VAT returns
- Personal income tax for self-employed professionals
Annual returns:
- Modelo 190 / 180 / 390: Summaries of withholdings and VAT
- Modelo 347: Annual informative return for suppliers and clients over €3,005
- Modelo 200: Corporate Income Tax return, due within 25 days after six months from year-end
Reviewing your tax position before closing the year allows you to detect possible adjustments, optimize deductions, and plan liquidity for upcoming payments.
5. Determine Whether an Audit Is Required
An audit of annual accounts is mandatory if, for two consecutive years, at least two of the following three thresholds are exceeded:
- Total assets: €2,850,000
- Net turnover: €5,700,000
- Average employees: 50
If your company meets these conditions, the auditor must be appointed before the year-end and the audit report must be included in the accounts filed with the Mercantile Registry.
Auditing provides an additional layer of transparency, reinforcing trust among investors, shareholders, and business partners. So, in the legal checklist we must include this.
6. Review Corporate Governance and Board Obligations
Before closing the year, ensure that:
- All board resolutions and meeting minutes are up to date.
- Decisions regarding dividend distribution, restructuring, or share capital changes have been properly recorded.
- The company’s corporate information at the Mercantile Registry reflects its current structure and management.
Keeping your corporate governance documentation in order helps prevent administrative issues and strengthens the company’s legal standing.
7. Common Pitfalls to Avoid
Many companies overlook small but critical compliance details that can lead to major consequences:
- Not filing annual accounts may result in the closure of the company’s registry file and financial penalties.
- Late submission of books or audits can block access to financing or public contracts.
- Neglecting tax deadlines can lead to surcharges and reputational risks.
Maintaining a clear compliance calendar — ideally with professional assistance — is the best safeguard. So, in the legal checklist we must include this.
