What is the imputed rental value?

The imputed rental value is notional income of people who own residential property and live in it themselves. It is intended to correspond to the potential rental income from this property – even though no money is actually moving around. The imputed rental value must be declared as taxable income in the annual tax return.

In return, homeowners can deduct their mortgage interest and property maintenance costs from their taxable income on their tax return.

 

Why does the concept of imputed rental value exist?

The idea behind the taxation of the imputed rental value is that tenants and owners should be treated equally: Tenants cannot deduct their rental expenses from their taxes, but owners can offset the mortgage interest and the costs of maintaining the house for tax purposes. The imputed rental value tax is intended to compensate for this advantage.

How did the imputed rental value come about?

The imputed rental value was originally introduced in 1915 as a war tax. In 1934 however, it was adopted again in order to cushion the consequences of the global economic crisis. The tax was subsequently extended again and again.

Does the imputed rental value tax also exist in other countries?

In an international comparison, the taxation of the imputed rental value is unique to Switzerland; in most other countries, owner-occupied properties are not taxed as income. The question of whether the imputed rental value tax is still appropriate has been discussed for years. That is why a referendum is being held now.

3 pro arguments for abolishing the imputed rental value tax

  • Simplification: Tax returns will be simpler and clearer for people who own residential property and live in it themselves. This is because they will no longer have to declare notional rental income in their taxable income. At the same time, most deductions for maintenance, renovations and mortgage interest will be eliminated.
  • Affordability in old age: Pensioners in particular benefit from a lower tax burden, as the imputed rental value often accounts for a large proportion of their taxable income.
  • Debt reduction: In Switzerland it is often customary to leave a large part of the mortgage ongoing for tax reasons. This can jeopardize affordability after retirement or become a burden in the event of a sudden death. Furthermore, the state should not create incentives to take on debt for tax reasons.

3 against arguments for abolishing the imputed rental value tax

  • Elimination of deductions: Tax deductions for maintenance, renovations and mortgage interest will be restricted or eliminated, which may affect younger and heavily indebted homeowners in particular. An important exception: If you are buying a property for the first time, you can offset part of the debt interest for tax purposes in the first ten years. 
  • Less investment in buildings: As maintenance costs are no longer deductible, property owners may be less willing to renovate or invest in greater energy efficiency. Among other things, this could burden the construction industry and lead to fewer climate protection measures being taken.
  • Tax losses: The Confederation and cantons are likely to lose billions in revenue, which will have to be compensated for elsewhere.

These are the consequences if the motion is adopted

  1. Homeowners who live in their property themselves no longer have to declare notional income for theoretically possible rental income (imputed rental value) in their tax return. This applies to primary and secondary residences.
  2. At the same time, deductions for maintenance or renovation work on the property are no longer possible in the tax return. Energy-saving and environmental protection measures can also no longer be deducted from taxable income for federal tax purposes. Cantons may continue to grant such deductions.
  3. Mortgage interest for owner-occupied residential property can also no longer be deducted from taxable income. There is an exception for people who are buying residential property for the first time: Married couples can claim a maximum of CHF 10,000 in the first year, CHF 9,000 in the second year and so on, until no more deductions are possible after ten years. For single people it is half of this.
  4. A property tax for second properties is also to be introduced at cantonal level. This is in the interests of the mountain cantons in particular, which want to secure important tax revenues through this.
Subject If imputed rental value remains If imputed rental value is abolished
Imputed rental value Counts as taxable income No longer has to be taxed as income
Debt interest deduction Can be deducted as costs from taxable income with no limit Deduction only possible to a limited extent: for first-time buyers (max. 10 years) and for rented properties
Property tax Not collected The cantons can introduce a property tax on second homes
Deduction for energy-saving measures Is possible for federal and cantonal taxes Is only possible at cantonal level
Flat-rate and/or actual maintenance costs May be deducted for value-preserving renovations Can only be deducted for rented properties

 

If the motion is accepted, implementation is expected to take place from 2028 so that the cantons have sufficient time to adapt. If the motion is rejected, everything will remain as it is today.

As a homeowner, will I benefit from the abolition of the imputed rental value tax?

That depends on the amount of your mortgage, the interest rate, the condition of the property, your municipality of residence and the amount of taxable income. 

Any person whose mortgage interest is lower than the imputed rental value is likely to benefit. This means those who have bought cheaply, who have low interest rates or who have already repaid a large part of the mortgage. The abolition of the imputed rental value tax can also bring major tax advantages for pensioners, as it generally accounts for a higher proportion of their taxable income. First-time buyers of owner-occupied residential property are also likely to benefit, as they can claim part of the mortgage interest as an expense in their tax return for the first ten years. If you buy a new build, you need not expect high maintenance costs in the early days.

However, it is also possible that homeowners will pay more tax after the reform than before: Given the current low interest rates, the imputed rental value is higher than mortgage interest for most homeowners – so almost everyone would probably benefit from abolition. However, anyone who owns an older property in need of renovation can no longer offset the costs of the renovation for tax purposes, at least in relation to federal tax, and this may result in tax disadvantages during the year of the renovation. 

 

Regardless of the imputed rental value: What is important for homeowners

Fundamental questions are often forgotten in the discussion about imputed rental value, for example: 

  • "Will I still be able to afford my own home in the future?" 
  • "What happens if I have to make do with only a part of my previous salary due to illness?"
  • "How do I make sure that my family can stay in familiar surroundings even in the event of death?"

Homeowners should ask themselves such questions regularly – when buying their own home, when having children, when cohabiting or when planning for retirement. 

As part of an individual pension analysis, answers to questions about the affordability of a mortgage can be clarified and sensible solutions found:

  • Term life insurance offers protection for your family and allows, for example, part of the mortgage to be repaid – so that your loved ones can stay in their own home.
  • Disability insurance can close income gaps caused by permanent illness, for example. This ensures the long-term affordability of the mortgage – see table.
  • As part of individual pension planning, it is possible to reliably forecast the cash flows that can be expected after retirement. Various scenarios can be developed on this basis. The affordability of the mortgage plays a decisive role here.

You don't have to answer complex questions about your home on your own: We will advise you personally and would be happy to clarify whether and how your home would remain affordable for you in the event of a great misfortune or in old age.

Example calculation: Affordability in the event of disability

A simple rule of thumb for the affordability of a home is that housing costs should not exceed around a third of gross income. In the example below, this is no longer the case with a long-term illness of 41%. The situation can be alleviated with a private disability pension. At 34%, affordability is just about given. 

  Background: Married couple (person 1 employed), 2 children Situation without protection Situation with protection
