After the annual return is submitted, if a tax refund is due to the taxpayer, the tax authorities will issue a notice indicating overpayment of tax. A refund will be issued within 10 days of the issuances of the notice and any refund must be claimed within 3 months.
Taxpayers have the right to claim a tax refund with interest if tax paid is incorrect due to their own misinterpretation of the law or miscalculation numbers. The right to claim a refund in the case of taxpayer error is valid for 5 years after taxes are assessed.
If the tax paid is incorrect due to an error of the tax authorities, taxpayers also have the right to claim a tax refund with interest. The right to claim a refund in the case of tax authority error has no time limit.
If a taxpayer has paid one-half of a disputed tax assessment and successfully appeals that assessment, any taxes overpaid will be refunded with interest.
The amount of interest received with a refund is calculated daily based on the one-year time deposit interest rate set by the Directorate General of the Postal Remittances & Savings Bank of Taiwan each year.
