Companies could treat 30-40 percent of their investment in blockchain research and development (R&D) as tax-deductible expenses from February.

The Ministry of Finance and Strategy Monday unveiled its plan to encourage R&D on blockchain and the other 15 new technologies, including wearable robots and fine-dust reducing technologies.

Small-and-medium-sized companies could deduct up to 40 percent of their expenses for a tax deduction while the ratio is 30 percent for big enterprises.

The new tax plan would be effective in February after undergoing a deliberation.
