Meaning
Fiscal state occurring when the volume of debt provided by related parties exceeds the amount of equity investment according to established ratios. Regulatory scrutiny of thin capitalisation prevents multinational groups from shifting profits out of the country through excessive interest payments. The law limits the amount of interest expense that can be deducted for tax purposes.
Debt Ratio
Standard limits for the ratio of debt to equity are two to one for general enterprises and five to one for financial institutions. If the borrowing exceeds these levels, thin capitalisation rules trigger a disallowance of the interest associated with the excess debt. Companies must demonstrate that the financing follows market conditions to avoid this adjustment.
Interest Disallowance
Excess interest is treated as a dividend distribution rather than a deductible business expense. This reclassification under thin capitalisation law increases the effective tax rate of the domestic subsidiary. The rule applies even if the loan is secured by a third party guarantee if that guarantee is backed by a related entity.
Financial Structure
Planning for the capital needs of a factory requires a balance between shareholder loans and paid in capital. Effective management of thin capitalisation risks involves the documentation of the commercial reasons for the specific funding mix. Tax authorities monitor these internal flows to ensure that the capital structure reflects the actual needs of the operation.
