Every euro matters, and if you worked abroad, it is important to know that income tax overpayments are very common and can be refunded. However, many people still do not declare their income abroad and lose the money that legally belongs to them. This guide provides clear answers to the most common questions, based on more than 20 years of experience.
When working abroad, income tax is calculated and deducted from your salary. After the end of the tax year (for example, in the UK – from April 6 to April 5, in most other countries – from January 1 to December 31) or after finishing work and leaving the country, a tax return is submitted. The tax authority reviews the information and, if an overpayment is found, the money is refunded.
Usually, the process takes from a few weeks to several months depending on the country, the workload of the tax authorities, and the completeness and accuracy of the submitted documents. Well-prepared applications are processed faster.
If you do not have some forms, payslips can usually be used, or you can request copies from your employer.
Yes. It is a legally regulated part of the tax declaration process in every country.
Not always. The refund amount depends on the country’s rules, your income, applied tax credits, employment period, and the amount of tax paid. In some cases, when annual income does not exceed the tax-free threshold or tax credits apply, a large part of the tax may be refunded, but each case is assessed individually.
Yes. Tax refunds do not affect your future employment opportunities.
No. Only overpaid income tax is refunded. Social insurance contributions remain untouched and your pension rights or social guarantees are not affected.
Most countries have double taxation agreements. If taxes were paid correctly abroad, usually no additional tax obligations arise in your home country. In specific cases, it is recommended to check with your local tax authority.
No. Only the overpaid part of income tax is refunded. This is a standard and legal tax practice.
No. Even short-term or seasonal work can result in an overpayment if income tax was deducted.
Yes. Missing documents can often be recovered by contacting your employer, tax authorities, or using payslips and other proof of income.
You can declare taxes on your own, but mistakes (incorrect data, missed deadlines, unclaimed allowances) often delay or reduce refunds. Specialists help prepare documents, submit declarations, and communicate with authorities.
The next step is to fill out the registration form: Start your tax refund process. If you want to estimate your potential refund, use the tax refund calculator.
