Business Loan Origination Fees and Closing Costs on Schedule C: Why You Amortize Them Instead of Deducting Upfront (2026 Guide)

Published: October 27, 2026 · Reading time: 12 min

TL;DR: When a freelancer or sole proprietor borrows for the business, the interest is deductible on Schedule C, but the fees paid to get the loan (origination fees, points, and related closing costs) are generally spread over the life of the loan, not deducted in the year you pay them. In our worked example, $1,150 of fees on a $40,000, five-year loan produces a deduction of about $367 in the first year, not $1,150. If you pay the loan off early, the unamortized balance may become deductible that year. Standby and commitment fees follow different rules. This is general education, so confirm your numbers with a CPA or EA.

Most freelancers meet loan fees at closing. A lender hands over a settlement statement, an origination fee is skimmed off the proceeds, and the money that lands in your business account is less than the loan amount. Then tax season arrives and a question appears: is that fee a business expense I deduct this year, or something else?

The answer is "something else," and the difference is easy to get wrong. Many people deduct the whole fee in year one because it feels like any other business cost. This guide explains the rule, shows the math on a realistic loan, and covers the edge cases: early payoff, line-of-credit fees, legal fees, and loans that funded personal spending too.

What the Rule Actually Says

Loan fees sit at the intersection of two ideas.

First, a fee charged for the use of money is interest, and interest that covers future years is not deducted early. The Instructions for Schedule C (the 2025 edition, the most recent one I fetched) say in their line 16 interest instructions:

"If you paid interest in 2025 that also applies to future years, deduct only the part that applies to 2025."

For a cash-method taxpayer, the Internal Revenue Code backs this up. Section 461(g)(1) says interest that is properly allocable to a period after the close of the tax year in which it was paid:

"shall be charged to capital account and shall be treated as paid in the period to which so allocable."

Second, the costs of getting a loan are not deducted when paid. Treasury Regulation 1.446-5 covers "debt issuance costs," which it defines as transaction costs a borrower incurs that must be capitalized under Treas. Reg. 1.263(a)-5. Its rule is:

"If these costs are otherwise deductible, they are deductible by the issuer over the term of the debt as determined under paragraph (b) of this section."

Paragraph (b)(1) explains the mechanism: "these costs are treated as if they adjusted the yield on the debt." In practice, the fees reduce the issue price of the loan, which creates original issue discount (OID), and OID is deducted over the term.

IRS Publication 535 says the same thing in plainer terms for points and origination fees. The IRS discontinued Publication 535 after the 2022 revision and points to a topic-by-topic map of other resources, so the 2022 edition is the last one that discusses loan fees in detail. Its rules on this point come from regulations that have not changed.

"Because points are prepaid interest, you generally cannot deduct the full amount in the year paid."

That sentence is in a passage explaining that charges called "loan origination fees, maximum loan charges, discount points, or premium charges" are interest if they are "solely for the use of money."

Which Charges Fall Where

A closing statement mixes different kinds of charges. Sorting them is the first job.

Two notes on the table. First, the Schedule C instructions do not mention loan fees by name, so the "line 16b" placement is an application of the interest rules, not a quoted instruction. A preparer may handle presentation differently, and that is a reasonable thing to confirm. Second, the "usual treatment" column assumes the loan is used in your business. If it is not, the next section applies.

The Constant-Yield Method

When loan costs are not trivial, the regulations do not let you simply divide by the number of years. They require the constant-yield method. Publication 535 (2022) puts it this way:

"You generally deduct OID over the term of the loan. Figure the amount to deduct each year using the constant-yield method, unless the OID on the loan is de minimis."

Constant yield tracks the true cost of money over time. Early in the loan, when you owe the most, a larger share of the fees is treated as deductible. Late in the loan the share shrinks. That is why year one in the example below is larger than a simple straight-line slice.

The de minimis exception

Tiny amounts have a simpler path. Treasury Regulation 1.1273-1(d)(2) sets the de minimis amount as 0.0025 multiplied by the product of the stated redemption price at maturity and the number of complete years to maturity. For installment loans the regulation substitutes the weighted average maturity for the years to maturity, and it allows a self-amortizing loan to use 0.00167 in place of 0.0025.

If the OID is below that amount, Publication 535 (2022) says you can choose one of these approaches: constant yield, straight-line over the term, in proportion to stated interest payments, or all at maturity. The choice is made by deducting consistently on your timely filed return for the year the loan was issued.

On a $40,000, five-year loan, the de minimis amounts are small (about $226 using the weighted-average-maturity test and $334 using the 0.00167 alternative, per the worked example below). Most real-world fee packages exceed that, which is why the constant-yield method is the safe default to ask your preparer about.

Worked Example: A $40,000 Equipment and Working-Capital Loan

Dana is a freelance video producer who files Schedule C and uses the cash method. On January 1, 2026 she borrows $40,000 from a bank for a five-year term to buy camera and lighting gear and cover slow-paying client months. All of the money goes into the business.

The terms:

• Stated interest rate: 8.5 percent, 60 equal monthly payments, first payment January 31, 2026
• Origination fee: 2 percent, or $800, withheld from the proceeds
• Attorney fee to review the loan documents: $350
• Total loan costs: $800 + $350 = $1,150
• Cash received: $40,000 − $1,150 = $38,850

The monthly payment works out to $820.66. I computed the figures below with a short Node script (monthly compounding for the yield, with the loan costs treated as reducing the issue price as the regulation requires). The regulation's own examples compound annually, so a preparer's software may differ from these numbers by a few dollars. The structure is what matters.

First, the de minimis check, assuming each monthly payment falls exactly one month after the last, with the first one month after funding (so the 12th payment is a complete year after funding and the loan matures exactly 5 years out). With a stated redemption price of $40,000 and a weighted average maturity of about 2.26 years, the test amount is $0.0025 × $40,000 × 2.2555 = about $225.55. The alternative figure is $0.00167 × $40,000 × 5 = $334. Dana's $1,150 of costs is above both, so the OID is not de minimis and the constant-yield method applies.

Here is what each year looks like.

Totals are computed from unrounded monthly figures, so adding a column by hand can differ by a cent or two.

Three things stand out:

1. The all-at-once mistake overstates 2026. If Dana deducted the full $1,150 in 2026, her deduction would be $783.49 more than the constant-yield amount of $366.51 for that year. That is an overstatement an examiner can adjust, and it would leave her with no loan-cost deduction at all in 2027 through 2030, when the constant-yield schedule would have allowed one.
2. Straight-line is not the default here. Because the OID is not de minimis, the constant-yield column is the one the regulation points to. Straight-line ($230 a year) is shown only so you can see the gap.
3. The deduction flows through Schedule C. Every dollar reduces net profit on line 31, which feeds both income tax and self-employment tax calculations. How much that saves depends on Dana's other income and filing status, so this example does not put a dollar figure on the tax saved.

What if Dana pays the loan off after three years?

Suppose Dana sells equipment and pays the loan off at the end of 2028, after 36 payments, with an outstanding balance of $18,054.10. Through 2028 she has deducted about $925 of the $1,150 of loan costs ($366.51 + $312.85 + $245.66). That leaves roughly $225 unamortized.

Publication 535 (2022) says:

"If your loan or mortgage ends, you may be able to deduct any remaining OID in the tax year in which the loan or mortgage ends."

It lists refinancing, prepayment and foreclosure as ways a loan can end. It also cautions that if you refinance with the original lender, you generally cannot deduct the remaining OID in the year of the refinancing, and may instead deduct it over the term of the new loan. So the payoff story matters: a payoff from sale proceeds is a different fact pattern from a refinance with the same bank. Keep the payoff letter and ask your preparer to treat it correctly.

Loans That Also Funded Personal Spending

Everything above assumes the money went into the business. Many freelancers borrow once and spend twice. A business loan used partly to buy a laptop for the business and partly to cover a personal bill is a mixed-use loan.

Interest allocation follows the use of the proceeds. Temporary Regulation 1.163-8T(c)(1) allocates debt "in accordance with the use of the debt proceeds." If 70 percent of a loan funded business purchases and 30 percent funded personal spending, 70 percent of the interest is a business deduction and 30 percent is personal (and generally nondeductible).

For the fees, the IRS sources quoted in this article do not give a separate formula. Applying the same proceeds split to the loan costs is the consistent approach, and it is what you should discuss with a preparer. Our HELOC versus business loan guide covers how to keep a clean trace, and the owner's contribution versus owner's loan post covers when moving money between you and your business creates its own paperwork.

Line-of-Credit and Commitment Fees

A revolving business line of credit often carries an annual fee or a fee for keeping funds available. These are not the same as an origination fee.

Publication 535 (2022) says:

"Fees you incur to have business funds available on a standby basis, but not for the actual use of the funds, are not deductible as interest payments. You may be able to deduct them as business expenses."

The word "may" matters. If the funds are for inventory or certain property used in your business, the same publication says the fees are indirect costs that you "must generally capitalize them under the uniform capitalization rules." Most service freelancers will not be in that position, but a reseller or maker may be. See UNICAP and the small business exception for the threshold discussion.

The practical approach is to record these fees separately from origination fees and ask your preparer which line they belong on. For credit cards, see our business credit card guide. For short-term invoice financing, see factoring versus a line of credit.

What About the Interest Limitation?

Some readers hear "business interest" and worry about the Section 163(j) limit. The Instructions for Schedule C tell sole proprietors that if they are a small business taxpayer or meet one of the other filing exceptions for Form 8990, they report all their deductible interest on lines 16a and 16b. Many freelancers fall in that group, but confirm that you do. Our Section 163(j) guide explains who does and does not.

Prepayment Penalties

A lender may charge a fee if you pay a loan off early. Publication 535 (2022) addresses this in its discussion of mortgages, saying a penalty for paying off a mortgage early can be deducted as interest. It does not address every other kind of business loan in the same passage, and the treatment of a prepayment penalty on a non-mortgage loan can turn on the loan terms. If you owe one, bring the loan agreement to your preparer instead of assuming.

Related Equipment and Vehicle Loans

If the loan bought a depreciable asset, the interest and the asset are separate tracks. The interest (and the amortized loan costs) go on line 16b year by year. The equipment itself is handled through depreciation, a Section 179 election or bonus depreciation. See Section 179 for freelancers and the lease versus buy comparison. For vehicles, where only the business-use share of interest counts, read the business vehicle loan interest guide.

Common Mistakes

• Deducting every closing charge in year one. The most common error and the one the worked example quantifies.
• Deducting the loan principal or the whole payment. Only interest (and the amortized cost of getting the loan) is a deduction. Principal repayments are not.
• Ignoring the net-proceeds gap. If the lender withheld fees from your proceeds, your bank deposit is smaller than the loan balance. Your records should show both.
• Losing the closing statement. The fee breakdown is the only document that shows what each dollar was for. Keep it with the note and payment history under the retention rules in IRS receipt retention.
• Skipping the payoff letter. An early payoff may unlock the remaining balance, but only if you can show when and how the loan ended.
• Mixing personal and business use without a record. A written split on the day the loan funds is far stronger than a reconstruction later.
• Assuming the accounting method does not matter. The cash-method prepaid-interest rule is a reason to confirm your method; see cash versus accrual for Schedule C.

If You Already Deducted Loan Fees Upfront

If a prior return deducted all of a loan's costs in the first year, do not guess at the fix. Depending on the numbers and the years involved, the answer might be an amended return (see how to amend a Schedule C), a change in accounting method, or no action. A CPA or EA can tell which. The audit-proofing guide explains what documentation helps either way.

How CentSense Helps

Loan fees are a records problem as much as a tax problem. Scan the lender's closing statement the day you receive it, keep the loan agreement, and record the purpose of the money so the business-use split is documented when you need it. CentSense lets you scan receipts, categorize your business expenses and keep your records in one place, so the closing statement, the equipment receipts the loan paid for and the payment history sit together when your preparer builds the amortization schedule.

Frequently Asked Questions

Are business loan origination fees tax deductible for a sole proprietor?

Generally yes, but not all at once. Treasury Regulation 1.446-5 says debt issuance costs that must be capitalized are, if otherwise deductible, deducted over the term of the debt, and the Schedule C instructions say that if you paid interest that also applies to future years, you deduct only the part that applies to the current year. Whether a particular fee qualifies, and how much belongs to business use, depends on your facts, so confirm it with a CPA or EA.

Can I deduct the whole loan fee in the year I pay it?

Usually not. The IRS treats points and similar lender charges paid solely for the use of money as prepaid interest, and Publication 535 (2022) says you generally cannot deduct the full amount in the year paid. Debt issuance costs are generally spread over the loan term under Treasury Regulation 1.446-5. A small de minimis exception can allow other timing choices, but a typical fee on a multi-year loan will often exceed it. Check the test for your loan with a CPA or EA.

Where do amortized loan fees go on Schedule C?

Generally with interest on line 16b, because the regulations treat debt issuance costs like original issue discount, which is a form of interest. The Schedule C instructions do not list loan fees by name, so this placement is an application of the interest rules rather than a quoted instruction. Commitment or standby fees are different: Publication 535 (2022) says they are not interest but may be deductible as business expenses. Confirm placement with your preparer.

What happens to unamortized loan costs if I pay the loan off early?

You may be able to deduct the remaining amount in the year the loan ends. Publication 535 (2022) says that if your loan ends, you may be able to deduct any remaining original issue discount in that tax year, and a loan can end through refinancing, prepayment or foreclosure. It also warns that refinancing with the original lender can change the result, so the timing depends on how the payoff happened. Ask a CPA or EA before you claim it.

Is an annual fee on a business line of credit deductible?

Often yes as a business expense, but it is not interest. Publication 535 (2022) says fees you incur to have business funds available on a standby basis, but not for the actual use of the funds, are not deductible as interest, and that you may be able to deduct them as business expenses. If the funds are for inventory or certain property, capitalization rules can apply. Keep the credit agreement and ask a CPA or EA about your situation.

What if I used part of the loan for personal spending?

Only the business share of the interest is deductible, and the loan costs should generally follow the same split. Interest is allocated by how the loan proceeds are used under Temporary Regulation 1.163-8T, so a loan that funded both business equipment and personal spending needs a documented split. The IRS rules quoted here do not spell out a separate formula for fees, so apply the proceeds split consistently and review it with a CPA or EA.
