Corporate tax rate The Corporate Tax Rate represents the percentage of tax your organisation pays on the interest earned from your maintenance fund. This setting ensures that your maintenance plan reflects the net growth of the fund after tax deductions, providing a more accurate closing balance projection. How it works Each year, the system calculates interest on your maintenance fund using the Interest Rate on Funds . The Corporate Tax Rate is then applied to that interest amount to determine how much tax is deducted before it’s added to your balance. Example: Fund opening balance: $50,000 Interest rate: 2% → Interest earned: $1,000 Corporate tax rate: 28% Tax deducted: $280 Net interest added to fund: $720 This ensures that the growth of your maintenance fund matches what you would actually expect after taxes are paid. Updating the tax rate You can update the corporate tax rate at any time to reflect your organisation’s current tax obligations. As with other financial settings, any change affects future calculations only — past years that have already been approved remain unchanged. Keeping this rate accurate ensures that your plan’s closing balance and fund growth projections remain realistic. Summary The corporate tax rate is applied to interest earned from your maintenance fund. It ensures your closing balance reflects net (after-tax) growth. Updating the rate affects future projections only. This setting helps maintain an accurate and compliant financial forecast.
