When one business acquires another in Portugal, the price paid often exceeds the fair value of the identifiable net assets. That excess is goodwill (trespasse or goodwill in accounting terms) — and how a microenterprise records and taxes it is far from intuitive. The rules sit at the intersection of accounting normalisation and the corporate income tax code, and small businesses frequently get them wrong.
This article explains how goodwill is treated for a microentity applying the simplified Portuguese accounting standard, and what the fiscal consequences are.
What is goodwill and when does it arise?
Goodwill represents the future economic benefits that cannot be individually identified and separately recognised — reputation, customer base, location, know-how. In Portugal it typically appears in two situations:
- Acquisition of a business or establishment (the trespasse), where you buy a going concern as a whole.
- Business combinations, where the consideration paid exceeds the fair value of acquired net assets.
It is an intangible asset, but a special one: it cannot be sold separately from the business that generates it.
The accounting framework for microenterprises
Portugal’s accounting system (Sistema de Normalização Contabilística, approved by Decreto-Lei n.º 158/2009) offers different normative levels. Microentities that meet the legal thresholds may apply the Norma Contabilística para Microentidades (NC-ME), a simplified standard, instead of the full set of Normas Contabilísticas e de Relato Financeiro (NCRF).
Initial recognition
Under both NC-ME and NCRF 14 (Concentrações de Atividades Empresariais), goodwill acquired in a business combination is recognised as an asset at cost — the excess of the consideration transferred over the fair value of identifiable net assets acquired.
Subsequent measurement: amortisation vs. impairment
This is where microenterprises differ materially from larger entities:
- Under NC-ME, goodwill is treated like other intangible assets and is amortised over its useful life. Where that life cannot be reliably estimated, the standard generally points to amortisation over a capped period (commonly understood as up to ten years). Confirm the applicable period with your accountant, as guidance has evolved.
- Under full NCRF, goodwill with an indefinite useful life is not amortised but tested annually for impairment.
For most microentities, the practical result is a predictable annual amortisation charge in the accounts.
Tax treatment under the CIRC
Accounting amortisation does not automatically mean a deductible expense. The Código do IRC (CIRC) governs deductibility.
Goodwill acquired in a business combination
Article 45.º-A of the CIRC allows, under conditions, the deduction of the acquisition cost of goodwill arising in a concentration of business activities, spread evenly over a defined number of tax periods (historically twenty, i.e. a 5% annual rate). This is a fiscal regime independent of the accounting amortisation rate, so timing differences are common.
Goodwill not acquired onerously
Internally generated goodwill is never recognised as an asset and is not deductible. Likewise, goodwill associated with assets with an indefinite useful life may fall outside the deductible regime — the CIRC and the depreciation/amortisation rules (Decreto Regulamentar n.º 25/2009) draw careful distinctions here.
Practical takeaway: Keep your accounting amortisation and your fiscal deduction in separate columns. The book charge follows NC-ME; the tax deduction follows article 45.º-A of the CIRC. The two rarely match, and the difference is reconciled in field 7 of your Modelo 22.
VAT and the trespasse
The transfer of a business as a going concern can fall outside the scope of VAT under the Código do IVA (CIVA), where the acquirer continues the activity and the conditions of non-transmissibility (article 3.º, n.º 4) are met. Misclassifying this can trigger unexpected IVA liability, so the contract wording matters.
How EasyFin helps
Goodwill is one of the most error-prone areas for small businesses — the gap between book amortisation and the CIRC deduction trips up even experienced founders. EasyFin connects your accounting to a certified accountant who handles the recognition, the amortisation schedule, the Modelo 22 reconciliation and the IVA treatment of the trespasse correctly from day one.
If you are buying or selling a business and want the goodwill handled properly, get started with EasyFin here and we’ll match you with the right specialist.
Conclusion
For microenterprises, goodwill means juggling two parallel systems: the accounting amortisation under NC-ME and the fiscal deduction under the CIRC. Recognise it correctly at acquisition, document the fair value of net assets, and reconcile the timing differences each year. Done well, goodwill becomes a manageable, deductible cost rather than a tax-time surprise.
