Regularly incurred expenses during the capital construction period are recognized as deductible expenses when calculating corporate income tax.

On May 7, 2024, the General Department of Taxation issued Official Letter No. 1879/TCT-CS:

When starting production and business activities, if an enterprise has not yet generated revenue but incurs regular expenses to maintain its production and business operations (not including investment expenses for constructing fixed assets), and these expenses meet the stipulated conditions, these expenses are considered deductible when determining taxable income.

In cases where, during the investment phase, an enterprise incurs loan interest expenses, these expenses are included in the investment value. In cases where, during the basic construction investment phase, an enterprise incurs both loan interest expenses and earns interest from deposits, the interest expense can be offset against the interest income, and the remaining difference, after offsetting, will be deducted from the investment value.
