The Inland Revenue Board of Malaysia has released new guidance on restrictions to the deductibility of interest expenses. The rules are based on the recommendations of the OECD in Action 4 of its base erosion and profit shifting (BEPS) Action Plan. The rules are intended to prevent tax base erosion through the use of excessive interest expense deductions to reduce domestic tax. There are parts that have been customized based on domestic circumstances. The Malaysian rules cap allowable interest expense deductions at 20 percent of a taxpayer's income before interest, tax, depreciation, and amortization (EBITDA). Disallowed deductions for one year can be carried forward to the subsequent year.
