Business valuation is the process of determining the economic value of a company or equity interest using recognised financial methodologies, producing a documented, defensible value range for use in transactions, tax filings, shareholder disputes, or strategic planning. In Spain, valuation methodology for tax purposes is governed by Article 18 of the Corporate Income Tax Act (LIS) for related-party transactions and Article 9 of the Inheritance and Gift Tax Act (ISD) for inherited or donated business interests, with the Spanish Tax Agency (AEAT) empowered to substitute declared values with its own assessment when submissions are insufficiently supported. The principal methodologies — discounted cash flow (DCF), comparable transaction multiples, listed company multiples, and adjusted net asset value — must be selected based on the purpose and characteristics of the business and comply with International Valuation Standards (IVS); for listed companies, the CNMV requires independent fairness opinions in related-party transactions and squeeze-out situations.
Our valuations comply with International Valuation Standards (IVS) and are accepted by courts, tax authorities, and leading financial institutions. Independence and methodological rigour are the foundations of every report we issue.
Why Poorly Substantiated Valuations Destroy Value in Transactions and Create Tax Contingencies
Business valuations fail when the methodology is not matched to purpose, the assumptions are not challenged rigorously, or the independence of the valuer is compromised. In M&A negotiations, a poorly substantiated valuation creates a weak anchor in pricing discussions — the counterparty’s adviser will find and exploit every weakness in the model. For tax filings involving related-party transactions, inherited business interests, or shareholder exits, a valuation that cannot withstand AEAT scrutiny generates a contingency that negates the transaction’s intended efficiency. The AEAT has the power to substitute the declared value with its own assessment — and does so when the submitted valuation is insufficiently documented. For shareholder disputes, a report that lacks the independence and procedural rigour required by Article 335 LEC is excluded as evidence. In each scenario, the cost of a weak valuation vastly exceeds the cost of a rigorous one.
Our Business Valuation Process: Methodology, Modelling, and Defensible Documentation
Every engagement begins with a conversation about purpose: the methodological choices for an M&A negotiation differ from those for a tax compliance filing, a shareholder dispute, or a management incentive scheme. We select and apply the methods best suited to the purpose, the sector, and the characteristics of the business. For most commercial companies, we build a discounted cash flow model, construct a comparable transaction multiples analysis, and reconcile the two approaches into a documented, defensible valuation range. For holding companies and real estate-heavy businesses, adjusted net asset value carries significant weight and requires individual fair-value assessment of each material asset. For intangible-heavy businesses — technology, IP, brands — we apply recognised methodologies including the relief-from-royalty and multi-period excess earnings methods. We document every assumption, every methodological choice, and every source — because the credibility of a valuation depends on the quality of the reasoning, not just the arithmetic. Our due diligence and transfer pricing specialists contribute where the valuation intersects with financial analysis or related-party pricing.
Real Results in Business Valuations: 350+ Reports, 100% Accepted by Courts and AEAT
- 350+ valuation reports issued across transactions, tax filings, disputes, and regulatory purposes.
- EUR 4B+ in aggregate business value assessed.
- 100% acceptance rate by the AEAT and Spanish courts: methodology, documentation, and independence meet the standards applied in any review.
- Second-opinion reviews of counterparty valuations that identify aggressive assumptions and unsupported methodological choices before they become the basis of a transaction price.
- Purchase price allocations (PPA) under IFRS 3 following acquisitions: allocation of acquisition price to identifiable assets, intangibles, and goodwill.
Business valuations in Spain for tax purposes must comply with the methods recognised under Article 18 LIS (transfer pricing) and Article 9 ISD (Inheritance and Gift Tax). The AEAT may substitute the declared value with its own assessment — capitalisation of profits or assets — when the submitted valuation is insufficiently documented. For M&A transactions, valuations must comply with IVS as market best practice. For listed companies, CNMV rules require Fairness Opinions in related-party transactions and squeeze-out situations. The integration of valuation with succession planning is particularly important for family businesses: the value used in a tax-efficient donation or inheritance must be defensible before the AEAT while also reflecting the genuine business value on which the family’s long-term financial planning rests.
When a business valuation is required
A formal business valuation is required in a wider range of circumstances than most business owners anticipate:
- M&A transactions: any business acquisition or disposal requires an independent assessment of fair value to inform pricing negotiations and provide a defensible basis for the transaction price.
- Transfer pricing: Spanish tax law and OECD guidelines require that transactions between related parties — including share transfers within a group and intercompany loans — be priced at arm’s length, which requires a documented valuation methodology.
- Succession and estate planning: transferring business assets to the next generation through donation or inheritance triggers ISD obligations assessed on the fair value of the transferred assets. The empresa familiar exemption applies to the excess value above the assessed value, making accurate valuation critical.
- Shareholder disputes and exit rights: when a shareholder exercises exit rights (drag-along, tag-along, buy-sell) or a dispute arises about the value of a shareholder’s stake, an independent valuation is required to resolve the disagreement.
- Litigation and expert evidence: insurance claims, fraud investigations, and commercial disputes frequently require expert valuation testimony. Our valuations experts have experience as court-appointed peritos and independent experts in arbitration proceedings.
- Employee equity plans: employee share option plans and restricted stock unit programmes require periodic valuations for tax and accounting purposes.
Valuation methodologies: which approach for which context
The appropriate valuation methodology depends on the type of business, the purpose of the valuation, and the quality of available financial data:
DCF (Discounted Cash Flow): the theoretically most rigorous methodology, based on the present value of projected free cash flows discounted at the weighted average cost of capital (WACC). Appropriate for businesses with predictable cash flows and a clear long-term outlook. Sensitive to assumptions about growth rates and discount rates — robust sensitivity analysis is essential.
Comparable company multiples (CCA): applying EV/EBITDA, EV/Revenue, or P/E multiples derived from publicly traded comparable companies or recent private transactions to the subject company’s financial metrics. The most commonly used methodology in practice, subject to careful adjustment for size, leverage, growth, and liquidity differences between the subject and comparables.
Comparable transaction multiples (CTA): applying multiples from completed M&A transactions in the same sector. Particularly relevant when transaction pricing is the primary reference point (e.g., in M&A contexts).
Net asset value (NAV): appropriate for asset-holding companies (real estate, investment vehicles) where the underlying asset values are more meaningful than earnings multiples.
Dividend discount model (DDM): used for businesses that generate predictable dividend streams and where the dividend policy is stable.
In most business valuation engagements, we apply multiple methodologies and triangulate the results, providing a valuation range rather than a single point estimate — which is more honest about the inherent uncertainty in any business valuation.
Business valuation in Spain: specific considerations
Spanish business valuations have several features that distinguish them from valuations in other European markets:
- Closely held companies: the overwhelming majority of Spanish businesses are family-controlled and unlisted, which means that marketability discounts and minority interest discounts (where applicable) require careful calibration against Spanish market evidence.
- Regional economic differences: EBITDA multiples for equivalent businesses in Madrid, Catalonia, and other regions can differ due to the regional economic context, investor base, and market depth.
- Tax valuation rules: for ISD, IP, and tax purposes, Spanish tax authorities apply their own valuation methods (typically based on capitalised earnings or adjusted book value) which may diverge from market-based valuations. Documenting the reconciliation between tax-method valuations and market-based valuations is important for transactions with a fiscal dimension.

Principal Valuation Methodologies and When to Apply Them
Discounted Cash Flow (DCF): The DCF methodology values a business based on the present value of its projected future free cash flows, discounted at a rate reflecting the risk of those cash flows (the weighted average cost of capital, or WACC). DCF is most appropriate for businesses with stable, predictable cash flows and a clear growth trajectory — particularly useful when comparable transaction data is limited or when the business has unique characteristics that make multiples comparison unreliable. The DCF is sensitive to assumptions about terminal growth rates and WACC; sensitivity analysis across these parameters is an essential part of any robust DCF-based report.
EBITDA Multiples: The EBITDA multiple methodology values a business as a multiple of its normalised EBITDA, benchmarked against comparable transactions and listed company multiples in the same sector. This is the most widely used methodology in Spanish mid-market M&A transactions and PE valuations. The critical variable is EBITDA normalisation — adjusting for owner-managed compensation above or below market, non-recurring costs or revenues, and structural working capital requirements that inflate or deflate reported EBITDA.
Net Asset Value (NAV): NAV is most appropriate for holding companies, real estate investment vehicles, and businesses whose value is primarily in their assets rather than their earnings. Adjusted NAV incorporates a mark-to-market valuation of all assets (including unrealised gains on property or investments) and deducts the full liability stack including deferred tax obligations on unrealised gains — a step that many simplified NAV calculations omit and that sophisticated buyers or tax authorities will adjust for.
Hybrid Approaches: Complex businesses — conglomerates with distinct divisions, companies with a mix of trading and property assets, businesses in transition between growth and maturity — require hybrid methodologies that apply the most appropriate method to each component of value and aggregate into an overall range.
Five Pre-Engagement Questions for Business Valuation
- Do you know the normalised EBITDA of your business — adjusted for all non-recurring items and owner-managed compensation at market rates — and how it compares to recent transaction multiples in your sector?
- If the AEAT challenges the value you have used in a related-party transaction or inheritance tax filing, do you have a methodology report with sufficient documentation to defend the value before a tax inspector and, if necessary, an Economic-Administrative Court?
- Have you received a counterparty valuation in a shareholder dispute, partner exit, or acquisition process that you suspect does not reflect the business’s real value — and do you need an independent second opinion?
- Are you planning a purchase price allocation (PPA) following an acquisition, and do you have a valuation team that understands IFRS 3 and the CNMV requirements applicable to your specific transaction structure?
- Does your succession plan rely on a specific business valuation for the ISD family business exemption — and has that valuation been prepared with the tax authority’s methodology requirements in mind, not just market best practice?
Worked Example: Family Business Valuation for ISD Exemption
A founder of a Spanish manufacturing company (revenue EUR 18 million, normalised EBITDA EUR 2.1 million) planned to donate 60% of the company’s shares to her two children while retaining 40%. The family was relying on the ISD Article 20.2.c 95% exemption to minimise inheritance and gift tax on the donation.
Valuation challenge: The AEAT’s typical methodology for ISD purposes uses a capitalised earnings approach (applying a capitalisation rate specified in the ISD legislation to the last declared net profit). This often produces a value significantly different — typically lower — than a market-based EBITDA multiple valuation. The ISD method might value the 60% stake at EUR 3.8 million; a market EBITDA multiple approach might value the same stake at EUR 6.3 million. The tax base for ISD and the 95% exemption calculation depend on which value is used.
Our approach: We prepared a dual valuation — the ISD statutory methodology for tax filing purposes (producing a defensible tax base of EUR 3.85 million for the 60% stake, tax liability: approximately EUR 130,000 before the 95% exemption = EUR 6,500 total ISD) and a market-based valuation for family governance purposes (confirming a market value of EUR 6.1 million for the same stake, establishing the baseline for future partner buyout pricing in the family protocol).
Key compliance requirement: The ISD exemption requires documented active management (remuneration above 50% of total employment/business income) and maintenance for five years. We verified these conditions and documented them in the valuation report for AEAT defence purposes.
Valuation in Shareholder Disputes
When shareholders disagree on the value of a company — a partner who wants to exit, a contested buyout, a divorce proceeding affecting company shares — an independent, defensible valuation is the central piece of evidence. Spanish courts can appoint their own expert valuator, but parties who present a well-documented independent valuation at the outset typically have stronger positions in settlement negotiations and court proceedings.
We have prepared valuation reports in contested shareholder disputes, partner exit proceedings under Articles 348 bis and 352 of the Ley de Sociedades de Capital (which provide for partner exit rights and judicial valuation procedures), and divorce proceedings where company shares are community property. The standard we apply is consistent: methodology transparency, sensitivity analysis, and documentation sufficient to withstand cross-examination by the counterparty’s expert. Our valuations team has experience providing expert witness testimony in commercial court proceedings in Madrid and Barcelona.
BMC Ecosystem: Valuations Integrated with M&A, Tax, and Succession
Business valuations do not exist in isolation. A pre-transaction valuation informs the sale price negotiation managed by our business acquisition team. A succession planning valuation is coordinated with our succession planning and tax advisory teams to ensure the ISD exemption conditions are met. A purchase price allocation is coordinated with the accounting team implementing the IFRS 3 acquisition accounting. This integration means that valuation engagements produce not just a number, but a report that is actionable across the legal, tax, and financial dimensions of the client’s situation.
How Long Does a Valuation Take and What Does It Cost?
A standard business valuation report — covering a single entity with straightforward financial history and a clear purpose — requires three to six weeks from receipt of the required financial information. Urgent engagements can be completed in two weeks with immediate data availability. The scope of work and timeline extend for group valuations, businesses with significant intangible asset portfolios, or engagements requiring preparation for CNMV submission.
Valuation fees are fixed per engagement and do not depend on the value conclusion — maintaining the independence that makes a report credible before any audience. We provide a fixed-fee quote at the initial consultation once the scope is understood. For ongoing valuation programmes (for example, annual portfolio company valuations for PE funds, or periodic family business valuations for succession planning purposes), we structure retainer arrangements that provide efficiency without compromising independence.
We accept urgent mandates — including valuations required for imminent transaction deadlines or court submission requirements — on a fast-track basis. Contact our valuations team with your timeline and we will confirm availability and fee at the initial conversation.
