Below are tax filing rules for international students across major countries that Indian students most commonly apply to. The rules, deadlines, and refund eligibility differ significantly from one destination to another.
USA
The USA has the strictest tax filing obligation among all major study destinations. Every F-1 visa and J-1 visa holder must file at least one tax form each year, even with zero income. For the first five calendar years, F-1 students are classified as nonresident aliens for tax purposes. This means they're taxed only on US-source income and are fully exempt from FICA taxes, which cover Social Security and Medicare.
Students with no income file only Form 8843, which documents your presence as a student and protects your nonresident immigration status. Those with income must additionally file Form 1040-NR and should not use TurboTax, which is built for US residents and will produce an incorrect return.
Indian students have a specific advantage under Article 21(2) of the US-India Income Tax Treaty, which allows them to claim the standard deduction on their federal return, a benefit not available to nonresident aliens from most other countries.
- Filing requirement: Mandatory for all F-1 visa holders, including F-2 dependents, even with zero income
- Key form: Form 8843 and Form 1040-NR
- Filing deadline: April 15 if income was earned; June 15 if filing Form 8843 only
- Tax-free threshold: No standard threshold; exemptions depend on active tax treaty benefits
- Refund possible: Yes, if taxes were withheld on wages or scholarship payments, or if a treaty reduces your liability
UK
The UK operates on a PAYE (Pay As You Earn) system, where your employer automatically deducts income tax from your wages before you receive your pay. Most international students do not need to file a Self-Assessment tax return unless they have income from multiple sources, earn above the personal allowance, or receive a notice from HMRC.
If you worked only part of the academic year and tax was deducted from your wages, you are likely owed a refund, which you can claim directly through the HMRC portal without filing a full return.
India has an active tax treaty with the UK (UK-India Double Taxation Convention). Under this treaty, scholarship and fellowship income received by Indian students from a UK university might be partially exempt from UK income tax, but you must notify HMRC to claim this benefit.
- Filing requirement: Not mandatory unless income exceeds the personal allowance or HMRC issues a Self-Assessment notice
- Key form: SA100 Self-Assessment return; P60 or P45 for employment income records
- Filing deadline: January 31 (online Self-Assessment)
- Tax-free threshold: £12,570 per year (₹15.6 lakh)
- Refund possible: Yes, claim through HMRC portal if over-taxed through PAYE
Canada
Canada does not legally require international students to file a tax return if they have no Canadian-source income. Even if you earn no income, filing a tax return can help you access GST/HST credits. It also allows you to carry forward Tuition Tax Credits indefinitely and use them to lower your tax bill once you start working.
The Canada Revenue Agency (CRA) considers you a deemed resident if you stay in Canada for 183 days or more in a calendar year, which means your worldwide income becomes reportable in Canada.
India and Canada have an active Double Taxation Avoidance Agreement (DTAA) signed in 1997. If you continue using Indian bank accounts while studying in Canada, the DTAA can prevent double taxation and limit Non-Resident Ordinary interest tax to 15%.
- Filing requirement: Not mandatory if no Canadian-source income, but strongly recommended
- Key form: T1 Income Tax Return
- Filing deadline: April 30
- Tax-free threshold: CAD 16,452 (₹10.9 lakh)
- Refund possible: Yes, if income tax was withheld by an employer during part-time or on-campus work
Australia
Australia treats most international students as tax residents if they study for more than six months. This grants access to the tax-free threshold of AUD 18,200, meaning you pay no tax on the first AUD 18,200 you earn each year. If you earn below this amount but have tax deducted from your wages, filing a tax return allows you to claim a full refund.
Students with no income and no tax withheld do not need to file a return, but they must submit a Non-Lodgement Advice through their myGov account. Under the India-Australia tax treaty (Double Tax Avoidance Agreement or DTAA), certain scholarship income might be exempt from Australian tax, and taxes paid in Australia can be claimed against your Indian tax liability to avoid double taxation.
- Filing requirement: Mandatory if income exceeds AUD 18,200 or if tax was withheld on any income
- Key form: ATO Tax Return via myGov; Non-Lodgement Advice if no income and no tax withheld
- Filing deadline: October 31
- Tax-free threshold: AUD 18,200 (₹11.8 lakh)
- Refund possible: Yes, full refund if income was below AUD 18,200, but tax was deducted by the employer
Germany
Germany has one of the most student-friendly tax systems among major study destinations. The annual tax-free allowance (Grundfreibetrag) is €12,348 in 2026, which means you pay no income tax if your earnings stay below this limit. Students earning up to €603 (INR 64K) per month through a Minijob are exempt from income tax and social security contributions.
Students earning above the Minijob limit are classified as Werkstudenten (working students). Filing is voluntary for most students, but it is worthwhile if you worked during the year.
Under the India-Germany DTAA, income earned by Indian students from teaching or research assistance at German universities may be exempt from German tax for up to two years.
- Filing requirement: Voluntary for most students; mandatory if you receive a notice from the Finanzamt or have multiple income sources
- Key form: Steuererklärung filed through the ELSTER portal
- Filing deadline: July 31 for mandatory returns; up to four years after the tax year for voluntary returns
- Tax-free threshold: €12,348 (₹13.2 lakh) in 2026
- Refund possible: Yes, if tax was deducted and your annual income remained below the tax-free threshold
Ireland
Ireland uses a PAYE (Pay As You Earn) system, where income tax is deducted automatically from your salary. As a result, most international students working part-time do not need to file a formal tax return.
Instead of a fixed tax-free allowance, Ireland uses tax credits. For most PAYE workers, the Personal Tax Credit and PAYE Credit together make roughly the first €18,750 (₹20 lakh) of annual income effectively tax-free. Students earning below €13,000 are also exempt from the Universal Social Charge (USC).
India and Ireland have a DTAA that prevents double taxation. The treaty also caps tax on dividends, interest, and royalties at 10%, which can be relevant if you continue to hold Indian investments or NRO accounts while studying in Ireland.
- Filing requirement: PAYE workers with multiple income sources or who receive a notice from Revenue
- Key form: Form 12 for PAYE workers; Form 11 for self-assessed individuals
- Filing deadline: October 31 for self-assessed returns; PAYE refund claims can be made anytime through the Revenue portal
- Tax-free threshold: €18,750 (₹20 lakh) through combined tax credits; USC not applicable below €13,000 (₹13.9 lakh)
- Refund possible: Yes, if excess tax was deducted through PAYE during the year
New Zealand
New Zealand does not have a tax-free threshold, which means income tax applies from the first dollar you earn. The country follows a PAYE system, so tax is deducted automatically from your salary, and most students with only PAYE income do not need to file a tax return.
If you stay in New Zealand for more than 183 days within a 12-month period, you are considered a tax resident. This means your worldwide income, not just income earned in New Zealand, may become taxable there.
India and New Zealand have a DTAA, which helps prevent double taxation by allowing taxes paid in New Zealand to be adjusted against your Indian tax liability.
- Filing requirement: Required if you are self-employed, earn rental income, or have residual income tax above NZD 5,000 (₹2.65 lakh)
- Key form: IR3 return filed through myIR
- Filing deadline: July 7 (New Zealand tax year runs from April 1 to March 31)
- Tax-free threshold: None
- Refund possible: Yes. IRD automatically issues an end-of-year assessment and refunds excess tax if too much was deducted during the year.
