Are Business Loans Tax Deductible? A Guide for Colorado Small Business Owners

If you’re running a small business in Colorado, tax season probably brings a mix of stress and strategy. One of the more confusing topics, especially if you’ve taken out financing, is this: Are business loans tax deductible?

Loans can be a smart way to fund equipment, cover seasonal expenses, or fuel expansion, but the tax side of things often catches people off guard. It’s not always clear what’s deductible, what’s not, and where the IRS draws the line.

Whether you’re a solo operator in Colorado Springs, a retailer in Fort Collins, or building out a second location in Denver, this guide will help you understand what a business loan really means for your tax return—and how to handle it the right way.

What a Tax Deduction Really Means

When something is tax deductible, it reduces the amount of income you’re taxed on. So if your small business brought in $120,000 last year and you had $20,000 in legitimate deductions, you’ll only be taxed on $100,000.

Some expenses are easy to recognize—payroll, office supplies, software subscriptions. Loans, though, can be tricky. The money you borrow isn’t income. But it can affect your taxes in different ways, depending on how you use it and how you track it.

So, Are Business Loans Tax Deductible?

Here’s the short version: The loan itself isn’t deductible. The interest often is.

Let’s say you own a coffee shop in Boulder and you borrow $60,000 to open a second location. That $60,000 doesn’t count as income, so you won’t pay taxes on it. But if you pay $5,500 in interest over the year, you may be able to deduct that $5,500.

It’s a fine line—one that can mean a big difference in your final tax bill.

Understanding IRS Rules Around Business Loans

The IRS small business loans guidelines are pretty clear: the money you borrow to operate your business isn’t taxable, and repaying that money isn’t deductible. But the interest you pay to borrow it? That’s often considered a legitimate business expense.

You might be able to deduct:

• Interest paid on traditional business loans
• Interest from business lines of credit
• Credit card interest, if the card is used strictly for business
• Fees associated with borrowing money

Be careful with mixed-use loans. If you borrow money and use part of it for personal expenses, you can’t deduct all of the interest—just the portion related to the business.

Are Loan Payments Tax Deductible?

No, at least not the full amount. Your monthly loan payment typically includes two things: principal and interest. Only the interest part is deductible. The principal is just you paying back what you already received. It doesn’t reduce your taxable income.

If you’re not sure how much of your payment goes toward interest, look at your loan’s amortization schedule or check with your lender. Keeping accurate records matters—especially if the IRS ever wants proof.

What If You Use a Personal Loan for Your Business?

This happens a lot with small businesses and family-run operations across Colorado. You take out a personal loan to cover business costs, especially when banks are slow to lend.

So, is interest paid on a personal loan tax deductible?

Sometimes. If you used that loan solely for business, and you can prove it, the interest might qualify as a deduction. But if you mixed in personal expenses—rent, groceries, a car—you can’t deduct the full amount.

Keep those receipts. You’ll need them.

Lending Money to Your Own Business

This one’s a common question: If I loan my business money, is it tax deductible?

It depends on how your business is structured and how formal the loan is. If you’re a sole proprietor and you transfer personal funds into your business account, that’s not a loan—it’s a contribution.

But if you own an LLC or S corp and you loan money to it, complete with a written agreement, reasonable interest rate, and payment schedule, you may be able to deduct the interest your business pays you. It must be structured like a real loan. Otherwise, the IRS might not recognize it as one.

Government and SBA Loans in Colorado

If you secured an SBA loan or participated in a state or city-backed lending program, the same rules apply. The funds aren’t taxed when received, and the principal isn’t deductible.

But again, the interest you pay? That’s typically deductible. Same goes for application fees or guarantee fees if they’re clearly tied to the loan’s cost.

So if you’ve worked with Energize Colorado or one of our lending partners, you’ll want to document all related expenses so they’re properly tracked come tax season.

Tax Breaks for Borrowing Money

While the loan itself doesn’t reduce your tax burden, using that money often opens the door to other deductions.

Here’s what we mean:

Used your loan to buy commercial kitchen equipment in Fort Collins? That purchase might qualify under Section 179.

Used it to pay wages while launching a new service in Greeley? Payroll remains deductible.

Covered rent or utilities in Grand Junction with borrowed funds? Those operational expenses are deductible, regardless of where the money came from.

That said, most small business loans, especially those with competitive terms, aren’t intended to cover complex property renovations or structural changes that require building permits. If you’re planning major construction or remodeling, check with your lender first to confirm what’s eligible.

When borrowing is part of a larger growth or reinvestment strategy, it can improve your tax position indirectly but meaningfully.

Keeping Good Records Is Non-Negotiable

If you want to make the most of the business loan tax deduction, you’ll need to stay organized.

That starts with separating business and personal finances. From there:

• Keep a clean profit and loss statement
• Make sure you can determine your balance sheet
• Revisit and update your business plan to reflect new debt or financing
• Track every loan-related payment, including interest
• Maintain digital or paper copies of loan agreements, payment records, and statements

Clean bookkeeping isn’t just good practice—it’s your defense if the IRS questions your return.

What to Watch Out For

There are a few red flags that could cause trouble when claiming tax deductible loans:

• Deducting the full loan amount instead of just the interest
• Deducting interest on a personal loan without showing clear business use
• Failing to document a loan between yourself and your company
• Using borrowed money for capital investments but not tracking depreciation

These kinds of mistakes can cost you, either in missed savings or in audits and penalties. Don’t assume, but verify. 

Understanding accounting basics for small business owners can help you avoid these missteps early. Knowing how to track interest, categorize loan use, and separate business from personal funds will save you time—and reduce the chance of getting flagged during a review.

The Bigger Picture for Colorado Business Owners

Loans give you the capital to expand, hire, improve, and compete, but tax season is when poor tracking becomes a liability.

That’s why Energize Colorado encourages small business owners to work with a qualified accountant or tax preparer who understands local regulations and small business operations, even better if they’ve worked with other businesses in your sector, because retail, construction, tech, and services all have their own rules of thumb.

Frequently Asked Questions About Business Loans and Taxes

Are business loans considered income by the IRS?

No. The IRS doesn’t treat loan proceeds as taxable income because you’re expected to pay the money back. That’s why you can’t deduct the loan principal—it wasn’t counted as income to begin with.

Is business loan interest deductible on federal taxes?

Yes, in most cases. As long as the funds are used for business purposes and the loan is properly documented, the interest portion of your payments is typically tax deductible.

If I loan my business money, is it tax deductible?

Possibly. If you loan money to your business with formal terms—interest rate, repayment schedule, and written agreement—you may be able to deduct the interest your business pays you. Without documentation, the IRS may reclassify it as a capital contribution, not a loan.

Are loan payments tax deductible in full?

No. Only the interest portion of the loan payment is deductible. The principal repayment is not, because it’s simply returning borrowed funds—not a business expense.

What if I use a personal loan or credit card for business expenses?

If the funds are used strictly for business, you can often deduct the interest. But if the loan or credit card is used for both personal and business expenses, only the business portion qualifies. You’ll need clear documentation to support the deduction.
