Cantonal knowledge

Tax return in the Canton of Lucerne: what you should know

The Lucerne tax law applies equally throughout the canton – but how much you pay in the end depends heavily on your commune and on the deductions you claim.

79 communes and the system of tax units

The Canton of Lucerne has 79 communes and works with tax units: the taxable income yields the simple tax, which is multiplied by the units of the canton, the political commune and the parish. In tax year 2025, the cantonal tax amounts to 1.55 units – reduced from 1.60 in the previous year.

In 2025, the communal units range from 0.90 (Meggen) to 2.40 (Luthern and Altbüron); the City of Lucerne stands at 1.55, also reduced. This changes nothing about how your tax return is completed: what counts is your commune of residence and, if you move within the canton, as a rule the one at the end of the year.

eSteuern.lu.ch – new from tax year 2025

With eSteuern.lu.ch, the Canton of Lucerne provides a web-based online solution from the 2025 tax return onwards – with no software download. You open an account with your e-mail address and mobile number and start the tax return with the PersID and access code printed on your tax return. Receipts can be uploaded via the app, and after submission a correction window of 72 hours remains open.

eSteuern.lu.ch is an option for anyone who wishes to complete the return themselves; alongside it, the declaration software for download continues to be available. If you want to be sure that every item is recorded correctly and completely, we take care of it for you: we enter your details, discuss the draft with you and prepare the submission.

Typical mistakes that cost Lucerne taxpayers money

In practice, we keep seeing the same points: the new, higher family deductions of the 2025 revision are not used to the full. For commuting by private car, proof of necessity is missing, so that the travel expenses deduction is lost entirely. The insurance deduction is not used in full.

The new degressive social deduction for low incomes also often goes unnoticed, because it depends automatically on the correct details being entered. A specialist checks every item individually and points out missing receipts to you before the return is submitted.

Tax deductions in the Canton of Lucerne: make use of every option

Anyone who knows all permissible deductions and claims them correctly reduces their tax burden noticeably. We check every deduction item systematically for your situation. The following maximum amounts apply to tax year 2025 (cantonal and communal taxes); the canton's official overview is authoritative.

  1. 01

    Professional expenses & commuter deduction

    In the Canton of Lucerne, travel expenses between home and workplace are deductible up to CHF 6'500 per year (federal: CHF 3'300), plus meals away from home at CHF 15 per working day or a maximum of CHF 3'200 per year, as well as other professional expenses at a flat rate of 3 % of net salary (minimum CHF 2'000, maximum CHF 4'000).

  2. 02

    Insurance premiums & savings interest

    With pension fund or pillar 3a contributions, up to CHF 5'200 (married persons) or CHF 2'600 (single persons) is deductible; without such contributions CHF 6'700 or CHF 3'300 – plus CHF 700 per child (tax year 2025).

  3. 03

    Pillar 3a & pension provision

    Payments into tied pension provision are deductible up to CHF 7'258 (tax year 2025, employees with a pension fund); pension fund buy-ins come on top. We assign the certificates to the correct position and check whether the permissible amount has been used in full.

  4. 04

    Child deductions & childcare

    Child deduction of CHF 8'000 per child (CHF 13'200 if the child lives away from home), third-party childcare costs up to CHF 18'000 per child and, newly, a deduction for childcare by parents of CHF 2'000 per child – all for tax year 2025, introduced or increased with the tax law revision.

    Official source(opens in a new tab on steuern.lu.ch)
  5. 05

    Further education costs

    Job-related education and further training: up to CHF 13'000 per person and year (tax year 2025, Canton of Lucerne and federal level). This includes course fees, teaching materials, examination fees and travel costs to the course venue.

  6. 06

    Second-earner deduction & other deductions

    If both spouses are gainfully employed, a second-earner deduction of up to CHF 5'000 is possible in the Canton of Lucerne. In addition, there are donations to tax-exempt charitable institutions and contributions to political parties within the applicable limits.

There are also further items such as debt interest, maintenance payments, property costs or asset management costs. Which deductions can be substantiated in your situation is something we clarify before processing – free of charge and without obligation.

Withholding tax

Withholding tax in the Canton of Lucerne

If your salary is taxed directly at source, an ordinary tax return is not automatically necessary – but in certain cases it is mandatory or possible on a voluntary basis.

01

Who is subject to withholding tax?

In principle, foreign employees without a C settlement permit who are resident or staying in the canton – for example with a B or L permit. The tax is deducted directly from the salary; the Tax Office of the Canton of Lucerne is responsible.

02

NOV – subsequent ordinary assessment

From a gross annual income of CHF 120'000 from employment, the subsequent ordinary assessment is mandatory. Below that, it can be requested voluntarily – in writing by 31 March of the following year; thereafter, the NOV applies until the end of liability to withholding tax.

03

How we support you

We check the tariff code, marital status, other income and possible deductions and assess whether a NOV is worthwhile in your case. We then submit the application on time and prepare the complete tax return.

This information is for guidance only and does not replace an individual assessment. We check your specific situation before processing.

Typical situations in the Canton of Lucerne

Families benefit from the 2025 revision

With the 2025 tax law revision, the child deduction was standardised and raised to CHF 8'000, the third-party childcare deduction was increased to CHF 18'000 per child and a deduction for childcare by parents of CHF 2'000 per child was introduced. We check which of these deductions apply in your situation.

Commuters

Whether to the City of Lucerne, to Zug or to Zurich: in the Canton of Lucerne, the travel expenses deduction is capped at CHF 6'500 per year (tax year 2025). Anyone wishing to deduct the cost of a private car needs proof that public transport is not reasonable – we check this in advance.

Students at the University of Lucerne and HSLU

Lucerne is a university city: University of Lucerne, HSLU and PH Lucerne. Even with a part-time job, internship or scholarship, a properly prepared tax return pays off. For apprentices and students, our fixed price of CHF 35.– per tax year applies.

Low incomes: new social deduction

Since tax year 2025, Lucerne has had a degressive social deduction that specifically relieves low incomes. Whether and to what extent you are entitled to it depends on your net income – we work this out for you.

Property and imputed rental value in the Canton of Lucerne

Anyone who owns residential property in the Canton of Lucerne pays tax on the imputed rental value as income and can in return deduct mortgage interest, maintenance and administration costs. The key is a clean separation: repairs and replacements preserve the value and are deductible; an extension increases it and is not.

Especially in lakeside communes with high property values, a careful compilation of maintenance costs pays off – flat-rate or actual, whichever is more favourable for your tax year.

If your property is located in another canton or you own several properties, a tax allocation is made between the public authorities involved. We record all properties in full so that the allocation remains traceable.

  • Imputed rental value and property details recorded correctly
  • Mortgage interest and list of debts checked
  • Maintenance: value-preserving separated from value-enhancing
  • Flat-rate and actual deduction compared
  • Properties outside the canton taken into account

Additional service: CHF 65.– per property.

Communal comparison

Tax units of the communes in the Canton of Lucerne

In the Canton of Lucerne, the simple tax is multiplied by the tax units of the canton (1.55 in tax year 2025), the political commune and the parish. The following selection shows some of the larger and some particularly low-tax communes.

In 2025, the range extends from 0.90 (Meggen) to 2.40 (Luthern and Altbüron). Depending on where you live, your tax burden can differ considerably – which makes a tax return that fully exploits all permissible deductions all the more important.
