Is a Business Line of Credit Interest Tax Deductible?

Ever had that moment of confusion when you stare at your business expenses and wonder if something is truly deductible? If you’re running a small company, you’ve likely run across the phrase line of credit interest tax deductible. So, is it really a thing, or is it just accounting folklore? Let me explain: in many cases, yes, interest on a business line of credit (LOC) can be deducted for tax purposes. But – and there’s always a but – you need to follow specific guidelines to stay within the rules.

I’m writing this on behalf of Eboost Partners, where I work with small businesses seeking funding options. We help owners who want flexible financing – from $5,000 all the way to $2 million – without drowning them in complicated details. This topic is one I get asked about often, and I get it. Taxes can be frustrating. But with a friendly nudge in the right direction, you can figure out which interest expenses can lower your taxable income.

If you’ve been considering a business line of credit or you already have one, keep reading. We’ll discuss how interest on an LOC works, what the IRS says about it, and whether you can deduct it. And don’t worry, we’ll keep the jargon to a friendly minimum.

What Is a Business Line of Credit?

A business line of credit is pretty much a revolving loan that gives you access to a set amount of money. You borrow what you need and pay interest only on that portion. It’s like having a credit card, but the credit limit (and interest terms) might be more suited for business purposes. If you want more details on what is a line of credit or how to get a business line of credit, you can check out our dedicated post on that topic.

At Eboost Partners, we often see small business owners use a line of credit to fund inventory, manage cash flow, or cover unexpected costs (like seasonal dips or urgent repairs). It’s popular because it’s flexible, and flexibility is often key for a growing company.

How Does Interest on a Business Line of Credit Work?

Here’s the thing: with a business line of credit, you don’t borrow the entire credit limit all at once – unless you actually need every dollar. Instead, you can withdraw smaller amounts over time. And because interest is typically charged only on what you use, you might keep your costs lower compared to a fixed-term loan.

For example, suppose you have a $100,000 limit, and you only take out $20,000 for a couple of months. You’ll pay interest on that $20,000, not on the full $100,000. Once you repay a portion of that principal, the credit becomes available again. This rolling mechanism can save you from paying for resources you don’t really need.

Now, does business line of credit affect credit score? Usually, it can, but only if you make late payments or default. In most cases, regular on-time payments can help build your business credit.

IRS Rules on Deducting Business Loan Interest

The IRS is quite specific when it comes to business deductions. You don’t want to be caught mislabeling personal expenses as business ones. At Eboost Partners, we always remind our clients that a clear division between personal and business finances is crucial.

According to official IRS guidelines, interest is generally deductible if it’s an ordinary and necessary expense. That means it must be directly tied to running your business. So, if you’re a restaurant using a line of credit to buy equipment or a retail shop restocking inventory, the interest on that financing can often be considered a valid deduction.

What Qualifies as Tax-Deductible Interest?

An interest payment qualifies if you’re using the money entirely for business-related activities. That includes paying suppliers, handling payroll, or addressing short-term operational costs. The primary requirement is straightforward: the debt should be in the business name and used for the business.

When Is Interest NOT Deductible?

If you borrow using a business line of credit, but then spend some (or all) of it on personal items – maybe a summer vacation or a home renovation – any interest portion tied to non-business use likely isn’t deductible. Mixing personal and business finances can also cause trouble with the IRS. It’s best to keep them separate.

If you’re dealing with something like a home equity loan vs line of credit, be sure to track what’s used for your company and what’s not.

How to Deduct Interest from a Business Line of Credit

First, track the interest portion of each payment. Your lender should give you a breakdown of how much goes to principal and how much to interest. At tax time, that interest amount can often be listed as an expense on your profit and loss statement.

You also need the correct documents to show if the funds were genuinely for business. Bank statements, invoices, or receipts can help. If you’re using an overdraft line of credit for small, short-term needs, keep records of all charges. It doesn’t hurt to consult an accountant if you’re unsure.

Many business owners ask us, “Do I just include the interest on my typical tax forms?” Usually, yes. Business interest often goes on Schedule C for sole proprietors, or the relevant expense line if you’re filing as a corporation or partnership. But you’ll want to review what IRS form do I use to report business loan interest in the FAQs below for more details.

Examples of Tax-Deductible Uses for a Business Line of Credit

There’s a wide range of ways to use your business LOC that result in deductible interest:

• Purchasing Equipment: If you run a small tech firm and buy new computers or servers with your LOC, the interest on that portion is deductible.
• Inventory Management: Say you own a boutique and need to stock up on extra fashion pieces for a busy season. If you tap your LOC to do that, the interest for that amount often counts.
• Operating Expenses: Maybe you’ve had a slow month, and you’re short on payroll. If you borrow from your LOC to cover wages, the interest can be written off.
• Business Expansion Costs: If you’re opening a second location and need a quick boost of funds for the lease deposit or remodeling expenses (and it’s in the business name), you might be able to deduct the interest as well.

Keep in mind: while the interest is deductible, any late fees or penalties might not be. Always double-check with your tax advisor.

Business Line of Credit vs. Other Tax-Deductible Loans

Not all loans are equal when it comes to deducting interest. Sometimes the line between business and personal becomes fuzzy, especially if you’ve mixed expenses. It may also differ if you’re dealing with a line of credit vs credit card or line of credit vs loan. Let’s look closer at how a business line of credit stacks up against other financing sources.

Business Line of Credit vs. Term Loan Deductions

A term loan might give you a lump sum upfront. If you take out $100,000, you’re paying interest on the entire chunk right away. That interest can also be deductible if used purely for the business. However, a line of credit only charges interest on what you actually borrow at a given time, so if you never fully tap the entire line, you can save on interest costs.

Business Line of Credit vs. Business Credit Card Deductions

A business credit card can help you earn points or manage small purchases. But those interest rates might be higher, and you’ll typically owe interest if you don’t pay the balance monthly. If used correctly, interest on a purely business credit card can also be deducted. That said, mixing personal charges on a business card may lead to confusion or ineligible deductions.

Business Line of Credit vs. Mortgage or Personal Loan Interest

Using a personal loan or mortgage to fund business costs can get tricky. If you have a home equity loan vs line of credit scenario and you spend it on your business, the portion used for business might be deductible. But the record-keeping must be absolutely crystal clear. The same goes for a personal loan that you funnel into business expenses. Some folks do it, but it requires precise documentation.

Conclusion

Can you deduct the interest on a business line of credit? Most of the time, yes – so long as you’re using the funds directly for your enterprise. The IRS sees interest on legitimate business debts as an ordinary expense, and that can reduce your taxable income. But it has to be the real deal. If you’re tempted to borrow for personal splurges and then label it as “business,” think again.

From my perspective at Eboost Partners, the real magic of a business LOC is its flexibility. You borrow what you need, when you need it. Repayment terms can extend up to 24 months, and you can select daily or weekly automatic payments that suit your cash flow. Whether you’re stocking up on products, covering payroll, or tiding yourself over in a rough spell, a business LOC might help you breathe easier.
