Why intangible assets deserve attention on the balance sheet
For many Swiss SMEs — especially Sagls active in technology, design, pharmaceuticals or specialised consulting — the real value of the business lies not only in machinery and inventory, but in patents filed with the Swiss Federal Institute of Intellectual Property (IPI), registered trademarks, software licences and know-how accumulated over time. These items can represent a significant share of economic assets, yet their accounting treatment is often neglected until year-end closing or a tax audit.
In Switzerland, SMEs that prepare financial statements under Swiss accounting standards (Swiss GAAP FER) must rigorously distinguish between research costs, development costs, intangible assets acquired from third parties and those generated internally. The Sagl, with its minimum share capital of CHF 20'000 and lean management structure, is the corporate form in which these distinctions arise most frequently: a founder contributing a patent in kind, an acquisition of a trademark portfolio or an investment in R&D can permanently alter equity, amortisation and the tax base.
This guide explains how to recognise, value and amortise patents, trademarks and know-how in a Sagl's balance sheet, with reference to the Code of Obligations (CO), FER recommendations (in particular FER 10) and federal tax implications in force in 2026.
Types of intangible assets and recognition criteria
Not everything of economic value can be capitalised on the balance sheet. The following table summarises the main categories and the usual accounting treatment under Swiss GAAP FER:
| Intangible asset | Typical example in a Sagl | Balance sheet recognition | Amortisation |
|---|---|---|---|
| Acquired patent | Purchase of a patent from an external inventor or another company | Yes — at acquisition cost | Yes — over remaining useful life (max. legal term) |
| Internally developed patent | Research costs and IPI filing fees borne by the Sagl | Generally no — charged to the income statement | Not applicable |
| Registered trademark | Swiss or international trademark registration (Madrid System) | Yes if acquired; generally no if created internally | Yes — over useful life (often 5–10 years) |
| Know-how / trade secrets | Production processes, formulas, customer databases | Only if acquired under contract and reliably measurable | Yes — over contractual or estimated term |
| Software licence | Perpetual ERP licence or multi-year prepaid software licence | Yes if multi-year right of use | Yes — over licence term |
| Goodwill | Acquisition of business units at a premium | Yes — difference between price and net asset values | Yes — over useful life (5 years if not determinable, max. 20 years; FER 10) |
The cornerstone principle is identifiability and cost attribution: the asset must be separable or arise from a contract, and its cost must be reliably determinable. Know-how generated internally by the Sagl's workforce does not as a rule meet these criteria and remains an off-balance-sheet asset until it is transferred or acquired from third parties.
Valuation: capitalisable costs and contributions in kind
A Sagl can acquire intangible assets in three main ways, each with distinct accounting rules:
Purchase from third parties
The carrying amount equals the purchase price plus directly attributable costs: legal fees, transfer taxes, brokerage commissions and registration fees with the IPI. Annual maintenance expenses (patent renewal, trademark fees) do not increase the balance sheet value: they must be charged to the income statement as period costs.
Example: a Ticino-based Sagl purchases a patent for CHF 80'000, with CHF 3'500 in notarial and legal expenses. Carrying amount: CHF 83'500 in the «Patents and licences» account.
Contribution in kind at incorporation
When a shareholder contributes a patent or trademark upon founding the Sagl, an audit by a licensed auditor is mandatory under Arts. 777c and 628 CO. The value certified by the auditor becomes the acquisition cost of the asset and counts towards share capital or share premium.
The Federal Tax Administration (FTA) and the auditor will verify that the value has not been artificially inflated to reach the minimum capital of CHF 20'000: the auditor's report must document the method, comparables and remaining useful life.
Internal development and IPI costs
Research costs (exploratory phase, feasibility study) must always be recorded as expenses. Patent filing costs, claim drafting, translations and intellectual property consultant fees can be significant, but under established FER practice they remain period expenses if the patent is developed internally.
Prudent exception: if the Sagl explicitly acquires a right from a third party (e.g. assignment of a pending patent application), the acquisition cost is capitalisable.
Know-how by contract
Know-how acquired through an assignment or exclusive licence agreement can be recognised if the contract clearly defines its scope, term and consideration. The value equals the agreed price; in the absence of a market price, an actuarial valuation or discounted cash flow method is the minimum documentation required by the auditor.
Know-how generated by the Sagl's employees, not protected by patent and not subject to an assignment agreement, cannot be recognised.
Amortisation: useful life and methods
Intangible assets recognised on the balance sheet must be systematically amortised over their economic useful life, regardless of the legal term of the title. A Swiss patent may enjoy protection for up to 20 years from the filing date, but if the technology becomes obsolete in 8 years, amortisation must reflect this shorter window.
For SMEs applying Swiss GAAP FER, the following practical guidelines apply:
- •Patents: straight-line amortisation over the estimated useful life, with a maximum equal to the remaining legal term. Many Sagls adopt 10–15 years for industrial technologies, 5–8 for software and ICT.
- •Trademarks: if acquired, typical useful life of 5–10 years; ten-year renewal costs are period expenses and do not extend the carrying amount of the recognised asset.
- •Contractual know-how: amortisation over the term of the licence or assignment agreement; if indefinite, a prudent estimate (e.g. 5 years) with annual review.
- •Goodwill: amortisation over the estimated useful life (5 years if not determinable, max. 20 years; FER 10), unless an impairment assessment requires early write-down.
| Asset | Carrying amount | Useful life | Annual amortisation | Residual value after 3 years |
|---|---|---|---|---|
| Industrial patent | CHF 120'000 | 12 years | CHF 10'000 | CHF 90'000 |
| Acquired trademark | CHF 45'000 | 9 years | CHF 5'000 | CHF 30'000 |
| Know-how licence | CHF 60'000 | 6 years | CHF 10'000 | CHF 30'000 |
The straight-line method is the standard for Sagls. Amortisation of intangible assets should be recorded separately from tangible assets, ideally in dedicated sub-accounts in the chart of accounts (e.g. 14xx Patents, 14xx Accumulated amortisation patents) to ensure transparency during audit and tax filing.

Tax implications: profit tax and tax return
For federal direct tax and cantonal/municipal profit tax, intangible assets recognised on the balance sheet under recognised commercial principles are generally tax-deductible for amortisation in line with the accounting treatment, provided the useful life adopted is justifiable. The FTA generally accepts commercial amortisation; accelerations or excessive useful lives relative to actual use may be adjusted on the tax return.
Specific points of attention for Sagls:
- •Contribution appraisal: an excessive value for an asset contributed in kind reduces future amortisation but exposes the company to challenge if the commercial value is lower. Document market comparables and revenue projections.
- •Assignment or licence: royalties received from a patent held by the Sagl are operating income; the gain on disposal of the patent is taxable in the period's profit, net of the carrying amount.
- •Qualified participation: if the Sagl holds participations and disposes of them at a gain, do not confuse accounting goodwill from company acquisitions with intellectual property rights: these are distinct tax regimes.
- •Impairment: if a patent loses value (e.g. invalidity ruling or dominant competitor), an extraordinary write-down is tax-deductible if adequately justified in the manager's minutes.
Note on cantonal taxation: cantons apply different rates on profit tax (on average 12–21% combining federal, cantonal and municipal components). Amortisation reduces taxable profit to the same extent wherever the Sagl is domiciled, but effective rates affect the annual tax benefit of amortisation. Check your canton's tax calendar for filing deadlines.
Documentation and governance in a Sagl
Orderly management of intangible assets protects the Sagl in due diligence, bank financing or auditor review. Maintain an up-to-date register with:
IP rights register
IPI number, filing date, expiry, beneficial owner, historical costs and amortisation schedule.
Assignment and licence agreements
Know-how, confidentiality clauses, territorial limits and term to justify amortisation.
Appraisals and valuations
Contributions in kind, acquisitions and any impairment tests at year-end.
Manager's resolution
Approval of useful lives, impairments and capitalisation policies — mandatory for traceability.
Common mistakes and how to avoid them
Capitalising internal development costs
Inflating assets by recognising internal R&D as a patent without external acquisition is one of the most common causes of audit adjustments. Maintain the CO/FER distinction between research (expense) and acquired asset (capitalisation).
Confusing renewal expenses with improvements
Ten-year trademark renewal or annual patent fees do not increase the balance sheet value. Recording them as investment overstates assets and equity.
Amortisation period equal to maximum legal term
Automatically applying 20 years to every patent ignores technological obsolescence. The auditor and the FTA expect an economic rationale, not only a legal one.
Omitting impairment testing
At year-end, check whether subsequent events (litigation, new regulations, loss of key customers) require a write-down even before amortisation is complete.
Conclusion: invisible assets that must be made visible
For a Swiss Sagl, patents, trademarks and know-how often represent the decisive competitive advantage. Accounting must not turn them into arbitrary figures, but accurately reflect which rights were acquired for consideration, at what cost and for how long they will generate economic benefits. The practical rule is simple: what is purchased from third parties is capitalised and amortised; what is created internally is expensed, except for documented contractual exceptions.
With a structured chart of accounts, an up-to-date register of intellectual property rights and accounting software that clearly separates investments, amortisation and maintenance costs, year-end closing becomes a straightforward process rather than a scramble for justifications. Transparency on intangible assets enhances the balance sheet in the eyes of banks, investors and tax authorities — and enables the Sagl's manager to make informed decisions on licences, assignments and future innovation investments.
