Imputed rental value is being abolished.
Take advantage of tax benefits now.

The course in Swiss tax policy is set: with the planned abolition of the imputed rental value (Eigenmietwert), the possibility of claiming maintenance costs for tax purposes will also disappear in the future. For you as a homeowner, this means: investments in the value retention and comfort of your property are particularly attractive right now. Anyone who modernizes by the end of 2028 directly reduces their tax burden.

Why waiting doesn’t pay off.

The tax logic is simple: as long as the imputed rental value is taxed as income, value-preserving measures can be deducted. With a marginal tax rate of 20–30%, the tax office effectively pays for a considerable part of your renovation costs.
A calculation example: An investment of CHF 15,000 in new Griesser blinds can reduce your tax bill – depending on the canton and income – by CHF 3,000 to CHF 4,500. After the system change, you will bear these costs entirely yourself.

Deductible services. What you can optimize now.

Griesser offers you tailor-made solutions that are not only technically convincing but also increase your well-being:

Replacement & Renewal: Exchange outdated or defective external venetian blinds and awning fabrics for modern, durable Griesser quality.
Window shutters: Complete renewal of casement, sliding, or folding shutters in aluminum.
Automation & Smart Home: Upgrade manual systems to motor drives or an intelligent Griesser control system. This is considered value-preserving modernization.

Value retention directly from the manufacturer: Our service promise.

Aluminum shutters: The clever choice for your tax planning.

Maintenance-free instead of cost-intensive: While wooden shutters have to be painted expensively every few years (costs that will no longer be tax-deductible in the future!), aluminum from Griesser remains practically maintenance-free. You save yourself all future maintenance costs.
Weatherproof & Dimensionally stable: Rain, snow, or intense sunlight? Aluminum defies the elements for decades without fading or warping.
Security plus: A stable aluminum shutter is a mechanical obstacle and increases the burglary protection of your home – a reassuring feeling that lasts.

Answers
to your questions.

Why is modernization financially so attractive right now?

Currently, the imputed rental value in Switzerland is still taxed as fictitious income. In return, you can fully deduct value-preserving maintenance costs from your taxable income. With the planned abolition of the imputed rental value (expected by the end of 2027/28), this deduction will lapse. So, if you invest in new Griesser blinds or shutters now, you let the tax office co-finance part of the costs – often saving 20% to 30% of the investment sum.

Does the replacement of old shutters or blinds count as "value-preserving"?

Yes. The replacement of existing sun and weather protection systems with modern, equivalent solutions (e.g., new venetian blinds or shutters) is generally considered value-preserving maintenance. The conversion from manual operation to an automated control or a smart home system is also recognized as a deductible modernization in most cantons. Only in the case of a completely new building or luxury additions that were not present before (e.g., a first pergola on a previously open terrace) is it referred to as “value-enhancing”.

By when must the installation be completed to benefit from the tax deduction?

As a rule, the date of invoicing or payment is decisive for the tax return. Since the political implementation of the abolition of imputed rental value is heading towards the years 2027/2028, larger projects should be planned early. If you spread a large project over two calendar years (phasing/staging), you can often break the tax progression even more effectively and maximize your tax advantage.

Is the investment also worthwhile if I want to sell my house later?

Absolutely. High-quality Griesser products not only increase your current living comfort and lower energy costs through better heat management. They also contribute significantly to the value retention of your property. Well-maintained facade elements and modern automation solutions are strong arguments in a later sale and justify a higher market value.
