Accelerated Depreciation in Spain (Amortización Fiscal Acelerada)

What Is Accelerated Depreciation in Spain?

In Spain, companies can deduct the cost of tangible and intangible assets against their Corporate Tax liability as those assets depreciate over their useful lives. The amount of depreciation allowed each year for fiscal (tax) purposes may differ from the amount recognised in the financial accounts.

Accelerated depreciation refers to any method that allows a company to deduct more of an asset’s cost earlier than straight-line accounting would suggest. This creates a timing difference: taxable income is lower in the early years of an asset’s life and higher later, effectively functioning as an interest-free loan from the tax authority equivalent to the tax on the accelerated portion.

For foreign companies investing in Spain through subsidiaries, manufacturing facilities, technology infrastructure, or intellectual property, understanding the available depreciation rules is essential for modelling the effective post-tax return on capital expenditure.

How It Works in Spain

The Official Depreciation Tables

The primary reference for fiscal depreciation in Spain is the set of official depreciation tables published in Annexe to the Reglamento del Impuesto sobre Sociedades (Real Decreto 634/2015). These tables specify, for each asset category:

• Maximum annual depreciation coefficient (coeficiente máximo lineal): The fastest rate permitted under the straight-line method
• Maximum useful life: The slowest rate — the minimum annual deduction
• Period of depreciation: The range between maximum and minimum

Companies can choose any rate within their asset’s range, providing legitimate flexibility to accelerate deductions in high-profit years or decelerate in loss years.

Degressive and Digit-Sum Methods

Beyond straight-line, companies can apply:

• Degressive (declining-balance) method: Applies the maximum straight-line rate to the net book value rather than cost, front-loading deductions
• Sum-of-digits method: Assigns a larger fraction of cost to early years by reference to a declining sequence of digits

Both methods are permitted for most asset categories except buildings, furniture, and fixtures, provided the total depreciation does not exceed 100% of cost.

Free Depreciation (Libertad de Amortización)

Free depreciation is the most powerful regime: it allows a company to deduct the full cost of qualifying assets in any pattern it chooses — including 100% in year one. The key qualifying categories are:

1. R&D assets: Tangible and intangible assets exclusively used in R&D activities (per Article 12.3 LIS)
2. Assets acquired under SME incentives (Empresas de Reducida Dimensión): Companies with turnover below €10 million can apply free depreciation to new assets up to a limit (currently €25,000 per year) under Article 102 LIS
3. New employee investments (free depreciation with job creation): Available to SMEs that increase their average headcount and invest in new assets; the free depreciation amount is linked to the average cost of the new employees (Article 102 LIS)
4. Canary Islands Zone (ZEC) and Canary Islands Investment Reserve: Specific investment incentives applicable to assets acquired in the Canary Islands

Intangible Assets

From 2016, following the removal of a specific super-deduction, intangible assets with finite useful life are depreciated at their accounting rate (which must reflect the actual economic life). Goodwill from business combinations is deductible at up to 5% per year for Corporate Tax purposes, regardless of any accounting impairment recognition. Internally generated intangible assets (including patents developed through R&D activities) are deductible at the higher of their amortisation rate or the R&D asset free depreciation rate.

Key Regulations

• Ley 27/2014 (LIS), Articles 12 and 102: depreciation rules and SME free-depreciation regime
• Real Decreto 634/2015 (RIS), Annex: official depreciation tables
• Ley 27/2014, Article 35: interaction between R&D assets and R&D tax credits
• Ley 19/1994 (Ley de la ZEC): Canary Islands investment reserve and specific depreciation incentives
• Spanish GAAP (PGC): accounting depreciation framework, which serves as the baseline from which fiscal adjustments are calculated

Practical Implications for Foreign Investors

Capital-Intensive Manufacturing and Technology

Foreign companies establishing Spanish manufacturing plants, data centres, or technology infrastructure benefit from Spain’s relatively generous maximum depreciation rates for machinery and computer equipment. Modelling the fiscal year-1 and year-2 Corporate Tax position using maximum or free depreciation (where available) is standard practice in greenfield investment analysis.

SME Regime Access

The SME regime (Empresas de Reducida Dimensión) threshold of €10 million turnover makes the free depreciation and other SME incentives accessible to most Spanish subsidiaries of foreign groups in their early years. Even subsidiaries of large multinationals that have just started operating in Spain will qualify until their local turnover exceeds the threshold — a valuable window for maximising early-year deductions.

Deferred Tax Implications for IFRS Reporting

Under IFRS (and local Spanish GAAP), the difference between fiscal and accounting depreciation creates a temporary difference that must be recognised as a deferred tax liability on the balance sheet. For finance teams of listed multinationals, this means accelerated depreciation increases the deferred tax liability and reduces the effective tax rate in the income statement — a double benefit in the short term but one that reverses as the assets age.

How BMC Can Help

Our tax team assesses the available depreciation methods and regimes for new investments in Spain, models the optimal depreciation strategy over a multi-year planning horizon, and prepares the annual tax adjustments for Modelo 200 to capture the maximum permitted fiscal deductions. We also advise on whether SME regime access is available given the group’s Spanish turnover history and how R&D assets can be structured to qualify for free depreciation alongside the R&D tax credit.
