Hidden reserves and depreciation: what to know
Hidden reserves and depreciation are two sides of the same coin: the difference between an asset’s book value and its real value. Understanding them means understanding why two companies with the same economic profit can pay very different taxes.
What hidden reserves are
A hidden reserve exists when an asset is carried on the balance sheet at a value lower than its real value, or when a liability is carried at a value higher than its actual value. The difference is “hidden” because it appears nowhere on the balance sheet: it is concealed within the individual items.
Hidden reserves arise in three main ways:
- Undervaluation of assets: depreciation faster than the actual wear and tear, valuation of inventory below cost, failure to revalue real estate.
- Overvaluation of liabilities: prudential provisions higher than the real risk.
- Failure to book capital gains on assets whose market value has risen.
The Swiss Code of Obligations (CO) expressly permits the creation of hidden reserves, a historical reflection of the prudence principle. This is a distinctive feature of Swiss accounting law: accounts serve first to protect creditors, then to inform.
Why they matter for tax
As long as a capital gain remains inside a hidden reserve, it is not profit and is therefore not taxed. The moment the reserve is released — because you sell the undervalued asset, or reduce an excessive provision — that value emerges as taxable profit for the financial year.
Hence the management value of hidden reserves: they are a tool for deferring tax and levelling out results over time. In a good year you set aside, in a weak year you release and cushion the impact. Be careful, though: it is deferral, not elimination. The tax gets paid sooner or later.
Depreciation: the most common lever
Depreciation is the accounting allocation of an asset’s cost over its useful life, and it is the most frequent channel through which hidden reserves are formed. In Switzerland there are two approaches:
- Straight-line depreciation: a constant amount each year on the acquisition value.
- Declining-balance depreciation: an amount calculated on a fixed rate applied to the residual value, and therefore decreasing over time.
The cantonal administrations publish tables with the maximum rates allowed for tax purposes by category of asset: vehicles, furniture, machinery, IT, real estate. As long as you stay within those rates, depreciation is recognised without argument. More aggressive depreciation is possible in accounting terms but may be added back for tax purposes.
Immediate depreciation and normal depreciation
Many cantons allow, within certain limits and for certain categories, immediate depreciation in the year of acquisition or over a short period. It is a powerful planning tool: it concentrates the cost in a high-profit year, compressing that year’s tax. The logic is always the same: you shift taxable income over time, you do not eliminate it.
The choice between normal and accelerated depreciation depends on your expected profitability curve. Depreciating everything at once is only advantageous if you have enough profit to absorb it; in a loss-making company you risk “wasting” the deduction.
The other side of the coin
Hidden reserves are not free. Some side effects need to be considered:
- Profit distribution: an artificially prudent balance sheet shows less profit available for distribution to shareholders.
- Access to credit: banks read a weaker asset base than the real one.
- Sale of the company: in a sale the buyer pays on the real value, and the accumulated hidden reserves become a matter for negotiation and, when released, for taxation.
- Liquidation: on winding up the company all hidden reserves emerge and are taxed in one go.
The balance to strike
Optimal management is neither “create as many hidden reserves as possible” nor “show all the profit”. It is finding the level of prudence consistent with your objectives: minimising tax over time without compromising your asset image when you need credit or want to sell.
At SIH ONE we treat depreciation and hidden reserves as multi-year planning levers, not as items to close off at year end. We check the cantonal rates applicable to your assets and simulate the tax impact of different policies before entering them on the balance sheet.
