A deferred tax liability (DTL) under IAS 12 arises when a company's accounting profit exceeds its taxable profit in a period — meaning the company will pay higher taxes in future periods when the difference reverses. Common sources of DTLs include: accelerated tax depreciation generating lower current taxes but higher future taxes, internally generated intangibles not recognized for tax but creating future taxable gains, revaluation of assets to fair value in IFRS accounts, and timing differences on revenue recognition. Unlike deferred tax assets, DTLs are not subject to a probability criterion and are recognized for all taxable temporary differences.

In a Purchase Price Allocation (PPA) context, DTLs are a key output: when fair value uplifts are recognized for identifiable intangible assets (brands, customer relationships, technology) in the PPA, a corresponding DTL is recognized for the tax that will be paid when those intangibles are amortized or realized. The DTL effectively reduces the fair value of the acquired intangibles on a net basis, lowering the goodwill adjustment. The DTL calculation requires knowing the applicable corporate tax rate in the relevant jurisdiction (25% in France, 11–21% in Switzerland depending on canton).

In a financial due diligence, material DTLs must be analyzed: they represent future tax cash payments and are a component of the debt-like item adjustment in the enterprise value to equity bridge. If the DTL relates to temporary differences that will reverse in the short term (within 3 years), they are often classified as debt-like and deducted from the equity value at closing.

At Hectelion, we identify and analyze deferred tax liabilities in our due diligences and PPA assignments, integrating them correctly into the enterprise-to-equity bridge.
