If the tax paid in advance abroad is overpaid, it is generally necessary to go to the local tax bureau for tax refund. But the specific situation depends on the type and amount of prepaid tax.

If the amount of prepaid tax overpayment is small, you can apply for tax refund directly on the personal income tax app. After selecting the tax refund application on the APP, the system will automatically calculate the tax refund and return the tax refund amount to the applicant's bank account within a few working days.

If the tax paid in advance is too much, it is impossible to apply for tax refund through the personal income tax app, and you need to go to the local tax bureau to apply for tax refund. The specific tax refund process may be different, and it is necessary to follow the regulations of the local tax bureau. You need to bring the tax payment certificate, ID card, bank card and other relevant supporting materials to the local tax bureau for tax refund.

In addition, you can also consult the staff of the local taxation bureau to understand the specific tax refund handling process and matters needing attention. It should be noted that overpayment of taxes generally refers to overpayment of taxes, rather than wrong collection or repeated collection of taxes, which needs to be dealt with according to specific circumstances and relevant laws and regulations.
