New Business Interest Expense Limit: Regardless of its form, every business will be subject to a net interest expense disallowance. Starting in 2018, net interest expense in excess of 30% of your business’s adjusted taxable income will be disallowed. However, your business won’t be subject to this rule if its average annual gross receipts for the prior three years is $25 million or less. Also, real property trades or businesses can choose to have the rule not apply if they elect the Alternative Depreciation System (ADS) for real property used in their trade or business. Since ADS is a slower way to depreciate property, real property trades or businesses will need to look at the trade-off between currently deducting their business interest expense and deferring depreciation expense. If you find yourself in this predicament, we can model out both scenarios to determine the best course of action.
