The Tax Cuts and Jobs Act expanded the number of small business taxpayers eligible to use the cash receipts and disbursements method of accounting and exempted these small businesses from certain accounting rules for inventories, cost capitalization and long-term contracts. The new law also amended Section 163(j) to disallow a deduction for net business interest expense of any taxpayer in excess of 30% of a business’s adjusted taxable income plus floor plan financing interest. This program is an in-depth discussion of these issues and many others related to accounting methods after tax reform.
