- Frequently asked questions
Suppose you have lived in your house in Unterägeri for many years and are seriously considering a sale for the first time. Your first question is about price. The Canton of Zug publishes no official figure for it, unlike the median values by municipality in the Canton of Zurich.
What the federal statistics do record is something else: 820 of the 1,511 buildings with residential use in Unterägeri were built before 1981. Only the city of Zug has a higher share. And more than one resident in five is 65 or older.
Sold one day after the 12th anniversary, the sale already counts as year 13 in Zug, and the tax in the same example falls.

What is a house in Unterägeri worth when there are no official price statistics?
The Canton of Zug keeps no price list by municipality, unlike the Canton of Zurich. Averages from property portals help just as little. They put a penthouse flat and a farmhouse, a 1965 build and a 2020 build into the same average.
Official records do show when buildings went up. 820 of the 1,511 buildings with residential use in Unterägeri were built before 1981, which is 54.3 per cent. Only the city of Zug has a higher share, at 61.3 per cent. Across the canton, the figure is 48.9 per cent. It describes the age of the houses, not their price.
Your price depends on location, plot and building, each assessed on its own and measured against comparable sales in the area. For a house from before 1981, what matters most is what has been renewed since. This item-by-item check is what lies behind the house valuation and the flat valuation. Your own range, in writing and with reasons, comes from the free assessment.
How much property gains tax do I pay on a sale in Unterägeri?
For property gains tax, the Unterägeri tax rate plays no part. Your return decides: the gain as a share of the investment costs, divided by the years owned. The result is your tax rate, never below 10 and never above 60 per cent, applied to the whole gain (§ 199 Zug Tax Act).
The longer you own, the lower the ceiling. Year 12: 57.5 per cent, then 2.5 points less each year, down to 25 per cent after 25 years. The way years are counted matters: after five years, every year started counts as a full one. Dates run from the land registry application. The municipality of Unterägeri carries out the assessment.
If your gain is under CHF 5,000, you pay nothing. A documented extension lowers the gain; a fresh coat of paint, being mere maintenance, does not. Replace your owner-occupied home with a new one in Switzerland, as a rule within two years. The tax on the reinvested part is deferred. Deferred is not waived.
Worked example
Example, Unterägeri: sale after 12 years
Suppose your purchase was registered in 2014 at CHF 400,000. The sale at CHF 1,000,000 is registered in 2026, exactly 12 years later to the day. You have not renovated and are not buying a replacement home.
- Sale price
- CHF 1,000,000
- Purchase price (in this case equal to the investment costs)
- – CHF 400,000
- Property gain
- CHF 600,000
- Total return: 600,000 as a percentage of 400,000
- 150%
- Tax rate: 150% divided by 12 years of ownership
- 12.5%
- Upper limit in year 12, well above the rate
- 57.5%
- Property gains tax: 12.5% of CHF 600,000
- CHF 75,000
- Remaining for you before mortgage repayment and selling costs
- CHF 925,000
What does selling in Unterägeri cost besides tax – notary and land registry?
The Canton of Zug takes no percentage of the price for a change of ownership. The land registry charges for time instead. An hour costs CHF 180, billed in quarter hours, each one started counted in full.
For a sale, the office quadruples that amount until the CHF 6,000 mark is reached. Past that point, the single rate applies again. Without another agreement, seller and buyer each pay half, but both are liable for the whole. The register for Unterägeri is kept centrally by the cantonal Land Registry and Geoinformation Office, Aabachstrasse 5, Zug.
For the notarisation, you go as a rule to the municipal clerk of Unterägeri, the official notary of the municipality. A law firm is not permitted to handle an ordinary house purchase. Cost: CHF 300 to 4,000 under the cantonal tariff, plus 10 to 50 per cent if the work takes more than an hour. So reckon in francs, not in a share of the purchase price.
More than half of all buildings with residential use predate 1981: what does that mean for a sale?
At 54.3 per cent, Unterägeri ranks 2 of 11 for the share of buildings with residential use from before 1981, behind the city of Zug at 61.3 per cent. The canton figure, weighted by all buildings with residential use, is 48.9 per cent. For many of these houses, heating, roof or windows will sooner or later be due for renewal.
A construction year before 1981 is neither a duty to renovate nor an automatic deduction from the price. What buyers want to see is evidence. Collect invoices, quotes and photos of heating, roof and windows in your sale documents.
From 2029, the imputed rental value and the deduction for maintenance costs on owner-occupied homes will be abolished. Anyone planning a renovation is therefore best advised to weigh timing and tax effects together. The guide Renovate or sell? sets out both paths side by side.
More than one resident in five is 65 or older: what follows for owners?
In Unterägeri, 2,021 of 9,527 residents are 65 or older, which is 21.2 per cent. The canton figure, weighted by population, is 18.9 per cent. Walchwil alone is higher (22.2 per cent), and Oberägeri ties with Unterägeri for rank 2 of 11.
Anyone who owns a house at this age faces a choice sooner or later. Either you sell it yourself, or you transfer the house to your children during your lifetime. Each path has its own tax and family consequences.
The guide Selling your house in later life describes a sale from your point of view. What applies to a gift to the next generation is explained in Transferring your house. Both paths deserve time; a decision under pressure rarely pays.
Value capture levy and building land: what applies in Unterägeri?
For newly zoned building land, the same rule applies across the canton: a levy of 20 per cent of the increase in land value falls due. The municipality keeps 60 per cent of it and 40 per cent goes to the canton. Whether rezoning, upzoning or development plans also cost something is set by each municipality in its building regulations.
Unterägeri has opted to charge one. Article 48 of its building regulations, adopted on 3 March 2024 and in force since 27 February 2025, requires 20 per cent of the increase in land value. Under cantonal law, it covers the part above a threshold of 30 per cent extra value or extra use. For upzoning, the floor area ratio must also rise by more than 0.3 or the building volume ratio by more than 1.2. Zoning changes made in the revision that introduced these regulations trigger no levy in principle. Substantial gains from them are settled by contract with the municipality.
On building land, a procedure is under way. On 24 February 2026 the Federal Department of the Environment, Transport, Energy and Communications (DETEC) approved the cantonal structure plan amendment «settlement boundary Unterägeri». For the planned zoning of the Schönwart/Wyden area, the canton must ensure protection of the Lorze-Sihl glacial landscape, an entry in the federal inventory of landscapes. Whether this zoning goes ahead is therefore not decided. For your own plot, no levy arises unless a planning change affects that very parcel.

The full process in detail What is your property in Unterägeri worth?
Which questions do owners in Unterägeri often ask?
How do I find the right estate agent in Unterägeri?
First ask where the price figure comes from, as there are no official statistics for Unterägeri. I handle sales across the Canton of Zurich and German-speaking Switzerland. A careful agent values land and building separately and calculates the tax under § 199 of the Zug Tax Act. The 12 checking questions serve as a checklist for this.
Inherited house in Unterägeri: does the value at inheritance count, or the old purchase price?
As a rule, the old purchase price: the municipality takes over the price and date of purchase of the person who left you the house. The inheritance itself does not yet count as a sale for tax purposes. The earlier period of ownership therefore counts too, which can lower the ceiling on the rate. How heirs go about a sale is shown on the inheritance page.
Do I pay a property transfer tax in Unterägeri?
No. Zug has no property transfer tax at cantonal or municipal level. Two fees apply instead: the land registry fee based on time, multiplied by 4 on a sale up to CHF 6,000 and usually split equally. On top comes notarisation by the municipality of Unterägeri, CHF 300 to 4,000 under the cantonal tariff.
Do I have to expect a value capture levy in Unterägeri?
Yes, as soon as a rezoning, an upzoning or a development plan affects your plot and the cantonal thresholds are exceeded. Unterägeri then charges 20 per cent of the increase in land value under Article 48 of its building regulations, in force since 27 February 2025. Land zoned for building for the first time falls under the cantonal levy instead, also 20 per cent. Without a planning change, no levy arises.
Do I have to renovate a house from before 1981 before selling?
No, the construction year alone does not oblige you to renovate before a sale. In Unterägeri the question affects many owners: 54.3 per cent of buildings with residential use date from before 1981, rank 2 of 11 in the canton. Complete records on heating, roof and windows matter more than a hasty renovation. Whether renewing first pays off is shown in Renovate or sell?.
What happens after the assessment if I decide not to sell?
Nothing. The free assessment is information, not an instruction. An instruction only exists once you expressly give one. If your figures favour keeping the house, that is what I will recommend. When and with whom you sell is up to you.
