In the second part of the eTax Solothurn guide, we have completed the following sections of our Swiss tax return (for the canton of Solothurn): insurance, pensions, retirement and finance (taxable assets).

Now we’ll continue with the categories, and in particular the interesting part about real estate!


Step 1: Properties (incl. real estate)

This chapter deals with real estate. This includes single-family homes, condominiums, rented real estate and rights of use such as the right of habitation or usufruct. Income from photovoltaic installations is also regarded as property income.

Whether and what you should enter here depends entirely on your housing and property situation. The following three scenarios (A, B and C) show you what is relevant in your case.

Real estate — Overview

Real estate includes all land and buildings, as well as rights registered in the land register (e.g. building rights). In the canton of Solothurn, the tax value is generally based on the cadastral value and is automatically calculated by the tax authorities.

If you own a property outside the canton of Solothurn, please indicate the tax value applicable in that canton. The conversion into Solothurn values is carried out by the tax office. Property abroad is declared at market value.

Scenario A: Renting

If you live in a rented property and do not own any real estate, you do not need to enter anything in this section.

The “Ownership / real estate” module is exclusively for owners and persons with a right of habitation or usufruct. As a tenant, you skip this section entirely. Your housing situation will be taken into account later in the deductions, not here.

Scenario B: Owner-occupied property

If you own a single-family home or condominium that you live in yourself, you must declare it here.

A lot of information is pre-filled or automatically calculated, for example:

Property data: number of rooms, apartments, garages and cadastral value

Property data: number of rooms, apartments, garages and cadastral value

Your task is to check the information and complete it if necessary (e.g. year of construction, number of rooms, garage).

Rental value
As a property owner, you will be charged a rental value. This is a fictitious income, just as if you were renting your own property. It is calculated automatically according to location, building type, year of construction and group of communes.

The most advantageous variant depends on your individual situation. The software automatically takes your choice into account.

Photovoltaic
Income from photovoltaic installations (e.g. feed-in tariffs) is treated as property income and must be entered here. Investment costs for energy-saving measures can also be taken into account, provided they are incurred during the tax year.

Scenario C: Rented property

If you own a property that is fully or partially rented out, taxation differs considerably from that of an owner-occupied property.

Rental income
Instead of declaring a rental value, here you declare gross rental income plus any other income (e.g. excess expenses).

In the case of multiple rentals or professional management, instead of providing individual data, you can also send a separate statement or management statement and enter only the totals here.

Real estate expenses when renting out
In particular, real estate forming part of private assets is deductible:

Not deductible are, among others, expenses that increase value, acquisition/sale costs and rents for owner-occupied accommodation.

Motor vehicles

In this section, you declare private motor vehicles such as cars or motorcycles that you own.

Motor vehicle details with purchase price, year of acquisition and tax value

Motor vehicle details with purchase price, year of acquisition and tax value

Enter the most important information:

The tax value is calculated automatically by eTax Solothurn:

So you don’t need to calculate the tax value yourself, just make sure that the purchase price and year of acquisition are entered correctly.

Notes:

If you don’t own a motor vehicle, you can skip this section.


Step 2: Other

Inheritances and donations

In this section, you declare the donations, heritages and inheritance advances that took place during the tax year (here: 2022) — regardless of whether money, material goods or real estate were passed on.

Donations, inheritances or inheritance advances received
If you have received assets, seize them separately for each transaction:

Typical examples are gifts of money, inheritance advances from parents or a contribution of wealth from an inheritance.

Donations or advances from heirs
If you have made gifts or inheritance advances yourself, you must also declare them — again, with the date, recipient and amount.

Important information
Are tax-exempt:

In these cases, it is not necessary to file a separate gift tax return.

However, if you have received free gifts from persons domiciled in the canton of Solothurn, or if you have received real estate in connection with the canton of Solothurn, you must within three months additionally send a gift tax return to the tax office of the canton of Solothurn (special taxes department).

This section has no influence on your taxable income, but it is central to proof of assets and origin. Please enter the information completely and truthfully.

Undivided inheritances

If an estate has not yet been divided (community of heirs), you do not file a separate tax return for the community of heirs. Instead, you are taxed on your share of income and assets in proportion to your share of the inheritance - from the day of the deceased’s death.

As usual, I only write and review things that I use in my personal daily life, or that I trust.
