If you work overtime, night shifts, weekends, or in physically demanding conditions, Austrian tax law rewards you with meaningful exemptions. These aren't deductions you claim on your tax return — they're built directly into payroll, meaning you see more money in your account every month without having to do anything extra. Understanding the rules helps you verify that your employer is calculating them correctly and ensures you're not leaving money on the table.
Overtime Pay: The First 18 Hours
Not all overtime is tax-exempt — only the premium portion, and only up to a point.
When you work beyond your contractual hours, your employment contract typically provides for an overtime supplement (Überstundenzuschlag) on top of your base hourly rate. In Austria, a 50% supplement is standard. It's this supplement that receives partial tax treatment — not the base hourly rate itself.
The rule for 2026: the first 18 overtime hours per month can receive a tax exemption of up to 50% of your basic hourly rate, subject to a maximum exemption of €200 per month.
How the Calculation Works
Say your gross monthly salary is €3,200 for a 38.5-hour week. Your basic hourly rate is roughly €19.18. You work 18 overtime hours in November, each with a 50% premium.
- Overtime supplement per hour: €9.59
- 18 hours × €9.59 = €172.62 tax-exempt
Since €172.62 is below the €200 monthly cap, the full supplement amount escapes income tax. The base pay for those 18 hours (18 × €19.18 = €344.55) remains fully taxable. Only the supplement gets the preferential treatment.
If you earn a higher hourly rate — say €25/hour — the supplement would be €12.50/hour, and 18 hours gives €225 in supplements. Here the exemption caps at €200, so €25 goes back into normal taxation.
What Happens Beyond 18 Hours?
Overtime hours 19 and above — both the base pay and the supplement — are fully taxable as normal income. There is no mechanism for further exemptions on additional overtime.
Night Work Supplements
If any part of your shift falls between 19:00 and 07:00, the supplement paid for that night-time work is tax-exempt up to €400 per month.
This applies to the specific nighttime premium your employer pays, not to your entire night shift wage. If your collective agreement (Kollektivvertrag) specifies a 25% night supplement and you work 60 night hours in a month at €20 base rate, your night supplement is €300 — fully exempt since it's below €400.
Night work exemptions apply separately from overtime exemptions. A shift worker who works overtime during night hours can potentially benefit from both simultaneously.
Dirty, Hazard, and Hardship Work Bonuses
Austria recognises that some jobs involve genuinely unpleasant or dangerous conditions. Supplements paid for work that is objectively dirty, hazardous, or physically wearing (schmutzige, gefährliche, oder erschwerende Arbeiten) are exempt up to €400 per month.
What qualifies is defined partly by regulation and partly by collective agreements in specific industries — construction, chemicals, waste management, and certain manufacturing roles are common examples. The bonus must be explicitly linked to these conditions; a general pay rise doesn't qualify.
Sunday and Public Holiday Supplements
Work performed on Sundays or Austrian public holidays commands a separate exemption. The supplement for Sunday and public holiday work is exempt up to €400 per month.
Austria has 13 public holidays per year, and Sunday work is regulated under the Arbeitsruhegesetz. Most collective agreements mandate premiums of 50–100% for this work. If your employer pays you a 100% Sunday premium on a €20/hour base, €400 of those supplements per month are tax-free.
Stacking the Exemptions
These four categories are independent. An employee can benefit from all of them simultaneously if their work situation warrants it. Consider a construction worker on a big infrastructure project:
- Works 18 overtime hours in October with a 50% premium on a €22/hour base rate → exempt amount: €198
- Simultaneously works night shifts with €350 in night supplements → €350 exempt
- Receives a €200 hazard bonus for underground work → €200 exempt
- Works on a public holiday with a €150 supplement → €150 exempt
Total tax-exempt supplements: €898 for the month. At a marginal tax rate of 35%, that's roughly €314 in saved income tax — plus the corresponding social security contributions that aren't charged either, since exemptions apply to both.
Social Security Is Also Reduced
This is often overlooked: the tax exemptions for overtime and shift supplements also reduce the social security contributions (Sozialversicherungsbeiträge) on those amounts. Employee contributions total around 18.12% of gross. On €898 of exempt supplements, that's an additional €163 in social security savings.
What You Need to Check on Your Payslip
Your payslip (Lohnzettel) should clearly separate:
- Grundlohn (base pay) — fully taxable
- Überstundenzuschlag (overtime supplement) — first 18 hours' worth potentially exempt
- Nachtzulage (night supplement) — up to €400 exempt
- Schmutzzulage / Erschwernis (hazard/hardship bonus) — up to €400 exempt
- Feiertagszuschlag (Sunday/public holiday premium) — up to €400 exempt
If your payslip bundles everything into one line without distinguishing supplements, ask your payroll department for a breakdown. Employers are required to apply these exemptions correctly — if they're not doing so, you're overpaying tax every month.
Can You Claim These on Your Tax Return?
Generally, no — these exemptions are applied by payroll in real time and should already be reflected in your monthly deductions. However, if you change employers mid-year or receive a lump-sum back payment for overtime worked in a previous period, the annual tax return (Arbeitnehmerveranlagung) reconciliation might be necessary to ensure everything was applied correctly.
If you suspect your employer has been applying the wrong amounts, the Finanzamt can audit your payroll records going back several years.
