Businesses borrow money for five main reasons: to smooth out cash flow between paydays, to buy inventory before selling season, to finance equipment and technology, to purchase real estate, and to fund expansion or acquisitions. The common thread is timing. Debt lets a company spend today the dollars it expects to earn tomorrow, and when the borrowed money produces more revenue than it costs in interest, the trade works. Debt is a standard part of corporate finance, not a distress signal, and the tax code actively favors it over raising money from investors.
Covering Payroll and Operating Expenses
The most common reason a business borrows is the least dramatic one: keeping the lights on between customer payments. Payroll, rent, utilities, and supplier invoices come due on fixed dates. Customer payments arrive on their own schedule. A perfectly profitable company can still run short of cash for weeks at a time.
A revolving line of credit closes that gap. The business draws funds when it needs them and repays once receivables come in. Business lines of credit typically carry annual percentage rates between 10% and 28%, depending on credit profile and whether the line is secured. That interest is the price of predictability, and it buys real protection. Under the Fair Labor Standards Act, employers who willfully or repeatedly violate wage requirements face civil penalties of up to $1,000 per violation, and willful violations can trigger criminal prosecution with fines up to $10,000.1U.S. Department of Labor. Fair Labor Standards Act Advisor – Penalties A single late-paying client shouldn’t cascade into missed payroll, and a credit line is what keeps it from doing so.
One detail catches many first-time borrowers off guard. Lenders almost always require a personal guarantee on a small business credit line, which means the owner’s personal assets are on the hook if the company defaults. The guarantee effectively pierces the liability shield an LLC or corporation would otherwise provide. Sign one with the same seriousness you’d bring to personal debt, because that’s what it becomes if things go wrong.
Buying Inventory Before Selling Season
Retailers and manufacturers routinely need to buy products months before they sell them. A toy company stocks shelves in August for December. A construction supplier locks in lumber prices in spring for summer building. Borrowing to fund those purchases makes the timeline work, and the math often favors it: bulk-purchase discounts can shave 5% to 15% off the cost of goods, easily covering the interest on a short-term loan.
Inventory financing uses the purchased goods themselves as collateral. Under Article 9 of the Uniform Commercial Code, a lender can take a security interest in a borrower’s inventory, giving the lender a legal claim to those goods if the loan isn’t repaid.2Cornell Law Institute. Uniform Commercial Code 9-102 Lenders typically advance 50% to 80% of the inventory’s appraised value, so the business still contributes some of its own capital. The loan gets repaid as goods sell, which makes this a self-liquidating form of debt when things go according to plan.
Purchase order financing is a related option for a business that lands a large contract but lacks the cash to fulfill it. The lender pays your supplier directly once you have a confirmed customer order. Costs run higher than a standard inventory loan because the lender is taking on more risk before any goods have been delivered.
Financing Equipment That Pays for Itself
A single piece of manufacturing equipment can cost hundreds of thousands of dollars. Specialized vehicles, commercial ovens, medical imaging machines, enterprise software platforms — these assets generate revenue for years but demand a massive upfront payment. Equipment financing spreads that cost over the useful life of the asset, typically three to seven years, so the monthly payment lines up roughly with the monthly revenue the equipment helps produce.
The tax code sweetens this considerably. Under Section 179 of the Internal Revenue Code, businesses can deduct the full purchase price of qualifying equipment in the same year it goes into service rather than depreciating it slowly over time.3Office of the Law Revision Counsel. 26 USC 179 – Election to Expense Certain Depreciable Business Assets For the 2026 tax year, that deduction maxes out at approximately $2,560,000 and begins phasing out once total equipment purchases for the year exceed roughly $4,090,000. On top of that, 100% bonus depreciation is available for 2026 following the restoration of full first-year expensing under the One, Big, Beautiful Bill Act signed in mid-2025. A business can potentially write off the entire cost of a financed asset in year one while spreading actual payments over several years.
The risk side is straightforward. Equipment loans are secured by the equipment itself, so if the business defaults, the lender repossesses the asset. Before signing, make sure the equipment will generate enough additional revenue or savings to cover the payments with room to spare. Financing a “nice to have” upgrade the same way you’d finance a revenue-critical machine is where companies get into trouble.
Owning the Building Instead of Renting
Ownership is one of the more powerful moves a business can make, and it requires the most debt. Commercial real estate loans typically require a down payment of 10% to 30% of the purchase price, with most conventional lenders targeting around 25%. SBA-backed loans can bring that down to as little as 10%.
The core advantage is stability. A fixed-rate mortgage locks in your occupancy cost for decades. Landlords can raise rent, decline to renew a lease, or sell the building out from under you. Ownership eliminates all three risks while building equity that strengthens your balance sheet, and that equity becomes collateral you can borrow against later.
The tax benefits are meaningful too. Commercial buildings are depreciated over 39 years under the general depreciation system, letting the owner deduct a portion of the building’s cost every year.4Internal Revenue Service. Publication 946 – How To Depreciate Property Mortgage interest is deductible as a business expense.
Commercial mortgages work differently from residential ones. Many are structured with a balloon payment: the loan amortizes over 20 or 25 years, but the entire remaining balance comes due after 5 to 10 years. At that point, the business either refinances or pays off the balance, which means a company could face a large lump-sum obligation at a time when interest rates are higher or the business is having a rough year. Lenders also evaluate borrowers heavily on the debt service coverage ratio (DSCR), the property’s net operating income divided by annual loan payments. Most lenders want a DSCR of at least 1.25; the SBA sets its minimum at 1.15. Falling below the required ratio after closing can trigger loan covenants or even a demand for early repayment.
Funding Expansion and Acquisitions
When a competitor comes up for sale or a new market opens, the window doesn’t stay open while you save up profits. Debt lets a business act on opportunities that would otherwise pass it by. Opening a second location, acquiring a supplier to control costs, or buying a rival’s customer base all require capital most growing businesses don’t have sitting in a bank account.
Larger deals trigger federal antitrust review.

New HSR Thresholds and Filing Fees for 2026 Filing fees alone run into the hundreds of thousands for large transactions, and the review can delay closing by months.
Acquisition financing usually stacks: senior secured loans carry the lowest interest rate and get repaid first, mezzanine financing sits underneath with higher rates and sometimes equity conversion rights, and seller notes let the previous owner finance part of the purchase price directly. Loan agreements for large growth financing almost always include financial covenants, ongoing requirements the borrower must meet throughout the life of the loan. Common covenants include maintaining a minimum debt-to-equity ratio, hitting a certain interest coverage ratio, and capping capital expenditures. Violating a covenant, even while making payments on time, can trigger a default that lets the lender accelerate the entire balance.
Why Debt Often Beats Equity on Taxes
One of the less obvious reasons businesses prefer debt over equity is the tax treatment. Money you borrow is not taxable income because it creates a corresponding obligation to repay. A $500,000 loan adds $500,000 to your bank account and $500,000 to your liabilities, with no net gain and no tax. By contrast, $500,000 from an investor typically means giving up ownership, and the money the business earns with it is fully taxable.
Interest paid on business debt is generally deductible, which reduces the effective cost of borrowing. If your business is in the 21% corporate tax bracket and you’re paying 8% interest, the after-tax cost of that debt is closer to 6.3%. That tax shield makes debt cheaper than it looks on paper.
There is a cap. Under Section 163(j) of the Internal Revenue Code, businesses can deduct net interest expense only up to 30% of adjusted taxable income.6Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense Interest above that ceiling carries forward rather than disappearing, but it limits the immediate benefit of heavy borrowing. Small businesses that meet a gross receipts test (averaging roughly $31 million or less over the prior three years, adjusted annually for inflation) are exempt entirely.
Loan origination fees and closing costs generally can’t be deducted all at once. They’re amortized over the life of the loan, so a $15,000 origination fee on a five-year loan translates to a $3,000 annual deduction. These costs add up across multiple loans and are easy to overlook when calculating the true cost of borrowing.
SBA Loan Programs for Small Businesses
The U.S. Small Business Administration doesn’t lend money directly, but it guarantees a portion of loans made by participating banks and credit unions. That guarantee reduces the lender’s risk, which translates into lower down payments, longer repayment terms, and better rates than most small businesses could negotiate on their own.
The SBA 7(a) program is the most versatile. It covers working capital, equipment purchases, real estate acquisition, debt refinancing, and business acquisitions, with a maximum loan amount of $5 million.7U.S. Small Business Administration. Terms, Conditions, and Eligibility SBA Express loans, a faster-turnaround subset, cap at $500,000. The SBA guarantees up to 85% of loans of $150,000 or less and 75% of larger loans, which is why lenders will approve borrowers who might not qualify for conventional financing.
The SBA 504 program is designed for major fixed-asset purchases like real estate and heavy equipment, with a maximum loan amount of $5.5 million.8U.S. Small Business Administration. 504 Loans The structure splits the cost three ways: a conventional lender covers roughly 50% with a first lien, a Certified Development Company (funded by an SBA-backed debenture) covers up to 40%, and the borrower puts in at least 10% equity.9Office of the Comptroller of the Currency. SBA’s Certified Development Company/504 Loan Program That 10% floor is well below the 25% to 30% most conventional commercial lenders require, which makes the 504 program especially attractive for a business buying its first property.
