Taiwan Securities Transaction Tax Revenue Tops NT$330 Billion in Record First Half

Taiwan’s securities transaction tax is a key gauge of stock-market activity and government revenue. The technology-sector boom has propelled the Taiwan Stock Exchange Weighted Index higher in recent years and attracted large capital inflows, making receipts from the tax an important indicator of investor confidence and economic momentum. With Taiwan stocks repeatedly setting records, fluctuations in the tax take also directly affect the Ministry of Finance’s progress toward its annual revenue target.

Taiwan collected NT$2.5 trillion in total tax revenue in the first half of 2026, up 81.5% from a year earlier, according to the latest Ministry of Finance data. Securities transaction tax receipts reached NT$333.6 billion as exceptionally active trading drove the total to a record and above the level for all of last year. Monthly receipts exceeded NT$80 billion for the first time in June, also setting a record and signaling that market liquidity remained strong.
