Deduction of Charges and Depreciation in Switzerland
Swiss tax law allows taxpayers to deduct various charges and depreciation from their taxable income, thereby reducing their tax burden. This tax optimisation represents a fundamental pillar of financial planning for both individuals and companies in Switzerland. The Swiss tax system, characterised by its three-level federalism (federal, cantonal and communal), offers a regulated but flexible framework for these deductions. Mastering these mechanisms provides a significant strategic advantage, enabling optimised tax management while strictly complying with current legislation.
Fundamental Principles of Charge Deductions under Swiss Tax Law
The Swiss tax system rests on the fundamental principle that only net income is subject to taxation. Under art. 27 of the Federal Act on Direct Federal Tax (FITA), taxpayers may deduct expenses necessary to acquire income and general deductions provided by law.
The deductibility of a charge is subject to three cumulative criteria:
- The charge must be connected to the income-generating activity
- It must correspond to an actual expenditure
- It must comply with the principle of tax periodicity
For individuals, deductions primarily concern professional expenses, passive interest, maintenance payments, training costs and certain social contributions. Legal entities may deduct charges justified by commercial usage.

Depreciation Methods Authorised
Swiss tax law recognises primarily two depreciation methods:
The straight-line method distributes the acquisition value of the asset uniformly over its useful life. This approach is generally preferred for real estate.
The declining balance method applies a constant percentage to the residual value of the asset. This method, more advantageous for tax purposes in the early years, is often used for technical equipment and movable assets.
Some cantons allow immediate or accelerated depreciation in specific situations, notably to encourage investment or innovation. These possibilities vary considerably from canton to canton and can be a strategic element in choosing a company's location.
Notable Cantonal Differences
Swiss fiscal federalism generates significant differences in the treatment of deductions between cantons. These differences notably concern:
- Admitted depreciation rates
- Provisions for specific risks
- Social deductions for individuals
- Deductions for energy or environmental investments
The tax planning across cantons constitutes a significant optimisation lever for companies with establishments in multiple cantons.
Frequently Asked Questions about Deduction of Charges and Depreciation
Which depreciation method is most advantageous for tax purposes?
The declining balance method is generally more advantageous for tax purposes in the early years of use, as it generates larger deductions when the asset is new. The straight-line method is more predictable and often preferred for real estate. The chosen method must be consistent from year to year and documented in the financial statements.
Can I deduct commercial provisions from my taxable income?
Yes, commercially justified provisions are deductible for self-employed individuals and companies. They must correspond to risks that are sufficiently certain and quantifiable at 31 December. Provisions for doubtful debts (generally 5% of Swiss receivables, 10% of foreign receivables), provisions for warranties and for pending litigation are the most commonly accepted. Solid documentation is essential.
Is my private vehicle used for work deductible?
For employees, only commuting costs between home and workplace are deductible (public transport or mileage allowance, capped at CHF 3,000 at federal level). For the self-employed, only the professional portion of vehicle costs is deductible, requiring a precise logbook. For companies, vehicles used for commercial purposes are depreciable and costs are deductible, subject to correction for private use.
Are energy renovation costs deductible?
Yes, energy-saving expenditure (thermal insulation, window replacement, renewable heating installation) is deductible as real estate maintenance costs. Since 2020, such expenditure can even be carried forward over the following two tax periods if it exceeds income for the same period. Cantonal subsidies may be added but do not conflict with the tax deduction.
