Most working students miss out on several hundred dollars every year simply because they never file a tax return. Yet a working student tax return is often the easiest way to get money back that can help pay for college. If you paid income tax during the semester, you'll usually get at least part of it refunded, sometimes even the full amount.

Why filing a tax return for your working student job almost always pays off

As a working student, you typically earn below the annual tax-free allowance. Still, your employer usually withholds income tax automatically once you're in the standard tax bracket and earn more than the monthly exemption threshold.

You get this withheld tax back through your tax return if your total yearly income stays under the exemption limit. This is especially common with a working student job, where your hours — and your income — tend to fluctuate between semester time and break periods.

When filing is actually required

In some cases, filing taxes for your side job isn't optional — it's mandatory. This applies, for example, if you have multiple employers at the same time or if you received wage replacement benefits such as short-time work compensation.

If you've been placed in the tax bracket for second jobs because you're working alongside a main job, it's worth checking whether filing is required in your case. When in doubt, check your tax office's online portal or ask a tax advisor.

Claiming study-related expenses: what actually counts

The biggest lever in a working student tax return is deductible expenses. Many students don't realize they can deduct costs related to their job and studies, even without substantial income from a permanent position.

  • Commuting costs: a fixed rate per mile for the one-way commute, with a higher rate kicking in after a certain distance
  • Work equipment like a laptop, textbooks, or a desk chair for your home office
  • Costs for a second degree or continuing education, if they're professionally relevant
  • Job application costs for your next position, such as printing costs or travel to interviews

Important: without a receipt, an expense usually won't count for tax purposes. That's why it's worth keeping receipts and invoices in a folder or app throughout the year.

Study costs as special expenses or deductible expenses

Whether you deduct study costs as special expenses or as work-related expenses depends on whether it's your first degree or a further degree. For a first degree without prior vocational training, these are usually treated as special expenses, capped at a certain amount per year.

For a master's degree after a completed bachelor's, or for a second degree, you can often deduct the costs without a cap as work-related expenses. This is especially worthwhile if you already have income from a working student job that these costs can be offset against.

Income tax for working students: how the refund process works step by step

Filing a tax return for a working student job sounds more complicated than it actually is. With the right documents and one of the common tax filing tools, it often takes no more than one or two hours to complete.

First, you'll need your annual income statement, which your employer usually submits electronically to the tax authorities and also provides to you as a copy. It lists your gross pay, withheld income tax, and social security contributions.

Next, you enter your income from employment and add your deductible expenses in the relevant section of your return. If you're unsure, use the official tax filing software provided by the tax office or a commercial alternative with a guided interview feature.

Deadlines you shouldn't miss

For a voluntary tax return, you have four years to file retroactively — so in 2025, you can still submit returns for the years 2021 through 2024. If you're required to file, the deadline is usually July 31 of the following year.

If you hire a tax advisor or join a tax assistance association, you often automatically get an extension until the end of February of the year after next. That can be worth it if you have little spare time between your studies and your working student job.

Using your tax refund to help pay for college

Depending on the amount, refunds often add up to $300–$800, sometimes more if you earned more or had significant deductible expenses. This money can help bridge rent payments or cover expensive textbooks.

If you still have financial gaps despite a working student job and a tax refund, it's worth weighing a working student job against a student loan to find the best combination for your situation. It's also worth taking a closer look at hidden college costs, since many students underestimate expenses like exam fees or field trips.

It's also worth checking out student discounts, which can save you several hundred dollars a year in everyday expenses.

Common mistakes with a working student tax return

A classic mistake is skipping the tax return altogether because you assume it's not worth it as a student. With income that fluctuates throughout the year, the opposite is usually true.

Another common mistake is forgetting to claim commuting costs or work equipment because no receipts were kept. Being in the wrong tax bracket when holding multiple jobs also frequently leads to unnecessarily high monthly deductions, which only get corrected once you file your side job tax return.

If you want to be better protected legally in general, it's also worth knowing the common legal mistakes in side jobs, for example around contracts or working hour limits.

Frequently asked questions about the working student tax return

Do I even have to file a tax return as a working student?

Filing is only mandatory in certain cases, such as having multiple employers at once or being in certain tax brackets. But filing voluntarily is almost always worth it if income tax was withheld.

How much money do I typically get back?

It depends on your income and deductible expenses, but refunds often fall between $300 and $800. With higher commuting costs or study expenses, the amount can be significantly higher.

What documents do I need for my tax return?

You'll need your annual income statement along with receipts for deductible expenses like commuting costs, work equipment, or tuition fees. Without proof, the tax office won't recognize most expenses.

Can I deduct tuition fees as a working student?

Yes, depending on the type of degree, either as special expenses up to a certain cap, or — for a second degree — usually without a cap as work-related expenses. This reduces your taxable income accordingly.

By when do I need to file my tax return?

For voluntary filing, you have four years to file retroactively; for mandatory filing, the deadline is usually July 31 of the following year. With a tax advisor, the deadline often extends to the end of February of the year after next.

Bottom line: a working student tax return is almost always worth it

If you work as a working student and pay income tax, don't let convenience stop you from filing a tax return. A working student tax return takes some time, but it often brings back several hundred dollars that can go straight toward paying for college.

Keep collecting receipts throughout the year, check your tax bracket, and if in doubt, use a tax assistance service or filing software to avoid mistakes. If a funding gap remains even after your refund, it's worth looking into additional options like a student loan or a scholarship to keep your college finances stable in the long run.
