Filing a tax return in Austria is one of the smartest financial moves you can make. The average Austrian employee who files receives a refund of several hundred euros. Yet many people — especially expats and newcomers — skip it because they don't know how or assume it's complicated. It isn't.
Do You Have to File?
Most employees do not have to file — your employer withholds Lohnsteuer (wage tax) throughout the year. However, you must file if:
- You had income from multiple employers simultaneously
- You had additional income not subject to wage tax (freelance, rental, foreign income)
- You received certain tax-exempt income that affects your bracket calculation
- The tax office sends you a request to file
Should You File Even If You Don't Have To?
Almost always, yes — especially if any of these apply:
- ✅ You have work-related expenses (home office, commute, equipment)
- ✅ You have childcare costs or family bonus claims
- ✅ You paid for professional training or education
- ✅ You made charitable donations to eligible Austrian organisations
- ✅ You had irregular income (sick leave, short-time work) during the year
- ✅ You only worked part of the year (started mid-year or left a job)
- ✅ You are an expat with foreign income
The worst case: you get nothing back. The best case: hundreds or thousands of euros refunded.
The Deadline
| Filing method | Deadline |
|---|---|
| Online (FinanzOnline) | 30 September of the following year |
| Paper form | 30 June of the following year |
| With a tax advisor | Up to 31 March of the second following year |
You can also file retrospectively for up to 5 years. This means you can still file for 2021, 2022, 2023, 2024, and 2025 right now if you haven't.
How to File: Step-by-Step via FinanzOnline
Step 1: Access FinanzOnline
Go to finanzonline.bmf.gv.at. You need:
- Your tax ID (Steueridentifikationsnummer) — 9 digits, received automatically when you register your residence
- Your registration code (sent by post after registering for FinanzOnline) OR
- Your mobile phone signature (Handy-Signatur / ID Austria)
If you've never registered, request access codes by post (takes 1–2 weeks) or visit your local Finanzamt.
Step 2: Start a New Return
From the main dashboard, select:
- Eingaben → Erklärungen → Arbeitnehmerveranlagung
- Select the tax year you're filing for
FinanzOnline pre-fills data it already has from your employer and bank (salary, withheld tax, etc.). Review everything carefully.
Step 3: Add Your Deductions
This is where most of your refund comes from. Add everything that applies:
Income-Related Expenses (Werbungskosten)
- Commuter allowance (Pendlerpauschale) — enter distance and commuting days
- Home office days (up to 100 days × €3)
- Work equipment purchased (laptop, desk, tools)
- Professional literature, software subscriptions
- Work clothing (if required and not suitable for everyday wear)
- Union fees (Gewerkschaftsbeitrag)
Special Expenses (Sonderausgaben)
- Charitable donations to eligible Austrian organisations
- Church tax (Kirchenbeitrag) — up to €400/year
- Voluntary pension contributions (Zukunftsvorsorge)
- Housing costs (under specific conditions)
Family-Related
- Family Bonus Plus (Familienbonus Plus) — €2,000/child/year under 18
- Childcare costs (up to €2,300/child under 10)
- Single parent allowance (Alleinverdienerabsetzbetrag)
Extraordinary Expenses (Außergewöhnliche Belastungen)
- Medical costs exceeding your deductible threshold
- Costs related to disability
- Nursing home costs for dependants
Step 4: Review and Submit
FinanzOnline shows a real-time summary of your expected refund or payment. Review every section, then click submit. You'll receive a confirmation number.
Step 5: Receive Your Refund
The tax office typically processes returns within 4–8 weeks. The refund is paid directly to your Austrian bank account (enter your IBAN in FinanzOnline). You receive a tax assessment notice (Bescheid) by post or electronically.
What Documents to Collect Before Filing
You don't upload documents to FinanzOnline — but keep them for 7 years in case of audit:
- Annual wage slip from employer (Jahreslohnzettel) — FinanzOnline pre-fills this
- Receipts for all claimed expenses
- Evidence of commuting distance (address, work location)
- Home office confirmation from employer
- Childcare receipts (name, amount, provider's tax number)
- Medical receipts for extraordinary expenses
- Donation receipts (from eligible Austrian organisations)
Most Commonly Missed Deductions
These are frequently overlooked and can add up significantly:
1. Work Equipment From Previous Years
You can claim equipment purchased in 2021–2025 if you haven't already (file amended returns).
2. Internet at Home
If you work from home, your home internet (work-related portion) is deductible — usually 50–80%.
3. Job-Related Books and Online Courses
Any education or training directly related to your current profession. This includes LinkedIn Learning, Udemy, or industry-specific courses.
4. Professional Association Fees
Memberships in technical societies, engineering associations, legal bodies, etc.
5. Moving Costs Due to Job Change
If you moved for a new job, a portion of your moving costs may be deductible.
6. Bank Fees on Work Accounts
If you maintain a separate account for freelance or business income.
Filing on Paper (Alternative)
If you prefer not to use FinanzOnline, you can file using Form L1 (for employees). Available from any Finanzamt or the BMF website. Submit by post to your local Finanzamt by 30 June.
The paper process takes longer and is more error-prone — FinanzOnline is significantly better.
Using a Tax Advisor (Steuerberater)
For complex situations (multiple income sources, foreign income, self-employment alongside employment), a Steuerberater is worth the cost. In Austria, their fee is itself tax deductible as a special expense.
Benefits:
- Extended deadline (31 March of the second following year)
- Expert knowledge of complex situations
- Representation in case of queries from the tax office
- Often finds deductions you'd miss yourself
Average fee: €150–500 for a standard employee return, depending on complexity.
Example: What a Typical Refund Looks Like
Profile: Employee earning €40,000/year, commutes 25 km each way, worked from home 60 days, bought a laptop for €900
| Deduction | Amount |
|---|---|
| Commuter allowance (large) | €1,476 |
| Pendlereuro credit | €50 direct credit |
| Home office (60 days × €3) | €180 |
| Laptop (work use 70%) | €630 |
| Total deductions | €2,286 |
At a 30% marginal rate: €2,286 × 30% + €50 = ~€736 refund
That's a meaningful sum of money — and filing takes less than an hour.
File Now for Previous Years Too
You can claim refunds going back 5 years. If you've never filed a tax return in Austria, you may be sitting on thousands of euros in unclaimed refunds. File for each year separately — FinanzOnline makes this straightforward.
Filing deadline information and deduction limits are based on 2026 Austrian tax law. Rules change — always verify current limits with the BMF or a qualified tax advisor.
