Companies often invest heavily in R&D to create an edge and remain competitive in their industry. It is essential to know how these R&D expenditures are treated for tax purposes and how they can help a company reduce its tax burden. R&D expenses can be deducted from a company’s taxable income, resulting in a lower taxable amount and therefore a lower overall tax bill.
