Higher interest rates have changed how businesses think about borrowing. Loans for equipment, expansion, real estate, and working capital now carry heavier payment burdens than they did just a few years ago. But recent federal tax law updates have made the business interest deduction rules more favorable again. Under revised Section 163(j) computations, many companies can deduct more of their interest expense in 2026 and beyond. At Nidhi Jain CPA, we translate these technical changes into practical planning moves for business owners.
What Section 163(j) Is Designed to Do
Section 163(j) limits how much business interest expense can be deducted each year. The rule was created to prevent excessive leverage from generating unlimited tax deductions. In general, deductible business interest is capped at 30% of adjusted taxable income, with excess carried forward. How adjusted taxable income is calculated, however, makes a major difference. Businesses working with a CPA often discover that small formula changes can produce large deduction shifts.
Why the Computation Is Now More Favorable
In recent years, the calculation tightened because depreciation and amortization were no longer added back when computing adjusted taxable income. That reduced the income base and therefore reduced the allowed interest deduction. New law updates restore a more EBITDA-like calculation for limitation purposes, adding back depreciation and amortization again. This increases the limitation threshold and allows more current-year interest deductions. Companies coordinating with a tax advisor should revisit prior projections under the updated formula.
What This Means in a High-Rate Environment
When rates are elevated, interest expense becomes one of the largest line items for leveraged businesses. If deductions are limited, the after-tax cost of borrowing rises even further. A more generous limitation formula directly lowers effective borrowing cost by allowing larger deductions today instead of years later. This is especially important for asset-heavy businesses maintaining loans alongside strong bookkeeping records that clearly separate interest from principal.
Carryforwards Still Matter
If your interest expense exceeded the limitation in prior years, the disallowed portion did not disappear — it carried forward. With the more favorable computation returning, some businesses may now unlock those carryforwards sooner. That can reduce taxable income in 2026 without new borrowing. Proper tracking and reconciliation are essential here, and a clean bookkeeping and accounting history makes recovery of suspended deductions much easier.
Interaction With Expansion and Equipment Financing
Interest deductibility should be evaluated alongside depreciation strategy, equipment purchases, and entity structure. Financing a large asset may now produce both immediate depreciation benefits and stronger interest deductions in the same year. That combined effect can materially change project ROI. Before signing new loan agreements, owners often consult a tax planning consultant to model tax-adjusted borrowing costs.
Debt, Taxes, and Mortgage Planning
Lower taxable income from higher interest deductions can help with cash flow, but may affect how lenders evaluate earnings for commercial loans or mortgages. Timing and presentation matter. We regularly align tax deduction strategy with financing readiness and business tax filing projections, so tax efficiency and borrowing goals support each other.
At Nidhi Jain CPA, we focus on business-forward tax planning, accurate records, and law-aware strategy so interest expense works as a tool — not a burden.
