1099-INT for Accountants: Who Gets It (and Who Doesn’t)

When you’re closing out the year and preparing information returns, Form 1099-INT often looks deceptively simple. It’s “just” interest income—but the rules around who should receive it, thresholds, exceptions, and reporting nuances can trip up even experienced accountants.

This guide walks through who gets a 1099-INT, when it’s required, edge cases to watch, and some common mistakes that lead to notices, mismatches, and unhappy clients.

What Is Form 1099-INT?

Form 1099-INT is used to report interest income of $10 or more paid to a U.S. person in a calendar year. Payors (banks, credit unions, brokers, businesses, and some individuals acting in a trade or business) must file this form with the IRS and furnish copies to recipients.

Interest reported on 1099-INT includes:

  • Bank deposit interest
  • Interest on corporate bonds
  • Interest on U.S. Treasury obligations
  • Certain interest on savings accounts, CDs, and money market accounts
  • Interest on deposits with brokerage firms
  • Interest paid by a business to another party in the course of business, in some situations

For accountants, the core question is: when does a client need to issue a 1099-INT, and when should they receive one?

Who Must Issue a 1099-INT?

1. Financial Institutions and Brokers

The most obvious filers are:

  • Banks and credit unions
  • Savings and loan associations
  • Brokerage firms
  • Mutual fund companies
  • Other financial institutions that pay interest

Any of these that pay $10 or more in interest to a payee during the year must issue a 1099-INT, unless an exception applies (such as payments to corporations).

Example:
A regional bank pays a customer $60 of interest on their savings account in 2025. The bank must issue a 1099-INT to the customer and file it with the IRS.

2. Businesses Paying Interest in the Course of Trade or Business

Non-financial businesses may also have to issue 1099-INT if they pay interest as part of their trade or business.

Common situations:

  • A business issues a promissory note to a lender and pays interest
  • A real estate developer pays interest to investors on funds used for a project
  • A corporation borrows from an individual or partnership and pays interest

If the payor is in a trade or business, and interest paid is $10 or more during the year to a non-exempt recipient, a 1099-INT is generally required.

Example:
A small S corporation borrows $50,000 from an individual shareholder at 5% interest. It pays $2,500 of interest during the year. The corporation must issue a 1099-INT to the shareholder.

3. Government and Certain Organizations

Government entities and certain tax-exempt organizations may also have 1099-INT reporting obligations, particularly when:

  • Paying interest on overpayments or tax refunds
  • Paying interest in connection with awards, settlements, or judgments
  • Paying interest on bonds or other obligations outside of traditional mutual fund reporting

While some of these are handled through specialized reporting channels, accountants serving public entities or large nonprofits should confirm whether a 1099-INT filing is necessary.

Who Receives a 1099-INT?

1. Individuals (U.S. Persons)

Any U.S. individual who receives $10 or more of reportable interest income during the year should receive a 1099-INT from the payor—unless they are otherwise exempt (e.g., a corporate payee in certain contexts).

Reportable recipients include:

  • Sole proprietors
  • Investors
  • Individual lenders
  • Employees who loaned money to the company separately from wages (interest on loans, not on wages)

Example:
Your client, an individual investor, holds several CDs at multiple banks. Each bank that paid $10 or more in interest will send a 1099-INT. Your client may receive multiple forms.

2. Partnerships, LLCs, Trusts, and Estates

Entities such as partnerships, LLCs taxed as partnerships, and many trusts and estates are not exempt from receiving 1099-INT. They are treated like individual recipients for reporting purposes (unless an exception applies).

Example:
A family trust holds a bond portfolio in its name, earning $5,000 of interest in a year. The brokerage will issue a 1099-INT to the trust’s EIN.

3. Some Corporations (But With Exceptions)

In general, corporations are exempt from receiving most 1099 information returns, including 1099-INT. However, payors still often need W-9s to confirm entity type and TIN.

That said, practitioners should remember:

  • Certain payments to corporations require other types of reporting (e.g., 1099-DIV, 1099-B).
  • Some specialized situations or misclassification can trigger “over-reporting” (e.g., payors issuing 1099-INT to corporations even when not strictly required).

When in doubt, check current IRS instructions to confirm the corporate exemption still holds for the type of payment.

Who Doesn’t Get a 1099-INT?

To avoid over-reporting and wasted time, it’s equally important to know who typically does not receive 1099-INT:

1. Corporations (Generally)

As noted, most corporations (including S corporations and C corporations) are exempt from Form 1099-INT reporting, unless a specific exception exists. Payors should confirm corporate status via Form W-9.

2. Tax-Exempt Organizations (Certain Cases)

Tax-exempt organizations, such as 501©(3) charities, usually do not receive 1099-INT for interest on their accounts. Financial institutions typically code these accounts appropriately.

3. Nonresident Aliens (Usually on 1042-S Instead)

Nonresident alien individuals typically do not receive 1099-INT. Instead, reportable U.S.-source income is usually reported on Form 1042-S, subject to different withholding and reporting rules.

If your client has foreign investors or nonresident alien lenders:

  • Ensure you collect Form W-8BEN / W-8BEN-E
  • Confirm whether 1042-S is required instead of 1099-INT

4. Interest Under $10

If total reportable interest to a payee is less than $10 in a calendar year, no 1099-INT is required to be issued. However, the recipient may still be required to report the income on their return.

Example:
A checking account earns $7.50 interest. The bank is not required to issue 1099-INT, but the taxpayer should still report the $7.50 on their tax return.

Edge Cases and Gray Areas

1. Personal vs. Business Interest Payments

If a payment is purely personal (not in the course of a trade or business), 1099-INT is not required—even if the amount is large.

Example:
A parent loans a child $100,000 for a home purchase, structured with an interest rate and schedule. The parent is not engaged in a lending business. No 1099-INT filing obligation exists, though the interest may still be taxable to the parent and deductible (in some circumstances) by the child.

In contrast, if the lender is a business regularly making loans, the 1099-INT obligation usually applies.

2. Brokered CDs and Pooled Investments

Interest earned through brokerage accounts, brokered CDs, or pooled investment vehicles can be reported on:

  • 1099-INT
  • 1099-OID
  • Combined 1099 composite statements

Each broker or financial intermediary determines how to allocate and report interest. For accountants, the question is not who gets a form (the brokerage handles that), but how to properly classify and reconcile interest on the tax return.

3. U.S. Treasury Interest vs. Municipal Bond Interest

  • U.S. Treasury obligations: Often reported on 1099-INT, but partially or fully exempt from state income tax.
  • Municipal bond interest: Generally tax-exempt for federal purposes and typically not reported on 1099-INT; instead it may appear on 1099-INT in Box 8 (tax-exempt interest) or be reported on 1099-DIV depending on structure.

The key for accountants: carefully track where the interest is reported and how it flows onto the return (e.g., Schedule B, Form 1040 lines, and state returns).

Common Mistakes Accountants Should Watch For

Even with clear rules, 1099-INT filing season is notorious for avoidable errors. Here are some common mistakes and how to prevent them:

1. Issuing 1099-INT to Exempt Entities

Mistake:
Issuing 1099-INT to corporations or tax-exempt organizations when not required.

Why it’s a problem:

  • Wastes time and money
  • Can confuse recipients and cause reconciliations issues
  • May trigger unnecessary inquiries or amended returns

Prevention:

  • Obtain and review Form W-9 for each payee
  • Track entity type and exemption status in your accounting system
  • Train staff on which payments/recipients are exempt from 1099-INT

2. Missing Interest Paid as Part of a Business Loan

Mistake:
Forgeting to issue 1099-INT for interest paid to individual lenders or partnerships when a business borrows money.

Example:
Your client’s LLC borrows from three individuals. All interest is paid in December, and the bookkeeper miscodes the payments as principal, not interest. No 1099-INTs are issued.

Prevention:

  • Review loan schedules and interest expense accounts at year-end
  • Reconcile total interest expense to 1099-INT amounts issued
  • Ask clients about informal loans that may not be clearly labeled in the books

3. Incorrect TINs or Names

Mistake:
Filing 1099-INT with mismatched names and TINs, or using a disregarded entity’s name with the owner’s TIN incorrectly.

Consequences:

  • IRS CP2100/CP2100A “B-Notices”
  • Potential backup withholding requirements
  • Increased risk of penalties for incorrect information returns

Prevention:

  • Collect complete Forms W-9 and verify against prior years
  • Use TIN Matching (if eligible) or third-party tools to validate
  • Ensure disregarded entities are reported under the owner’s name and TIN where required

4. Misclassifying Interest vs. Dividends or OID

Mistake:
Classifying payments as interest (1099-INT) when they should be dividends (1099-DIV) or original issue discount (1099-OID)—or vice versa.

Examples:

  • Distributions from certain corporate obligations miscategorized as interest
  • Deep-discount bonds where part of the return should be OID, not interest

Prevention:

  • Review the nature of the instrument and issuer documents
  • Follow broker or custodian reporting when available
  • For private notes or related-party instruments, carefully analyze terms (stated interest vs. discount)

5. Overlooking Backup Withholding Reporting

Mistake:
Failing to report backup withholding in Box 4 of Form 1099-INT when required, even when interest amounts are correctly reported.

Why it matters:
The IRS uses 1099 data to credit withheld tax to the recipient. If backup withholding isn’t reported:

  • The taxpayer may not get proper credit
  • Reconciliation errors and notices may follow

Prevention:

  • Track backup withholding in your client’s accounting system
  • Reconcile totals before 1099 filing
  • Double-check Box 4 entries for any payees subject to withholding during the year

6. Ignoring the $10 Threshold in Aggregation

Mistake:
Failing to recognize that the $10 threshold applies to total interest paid to a payee by a single payer during the year.

Example:
A business pays $6 of interest in March and $7 in October to the same individual lender. Because total interest is $13 (> $10), a 1099-INT is required, but the business incorrectly looks at each payment separately.

Prevention:

  • Use year-end reports to aggregate all interest by payee
  • Configure your accounting/1099 software to enforce per-recipient aggregation
  • Don’t rely on per-transaction thresholds

Practical Steps for Accountants Managing 1099-INT

To streamline 1099-INT compliance:

  1. Gather Payee Information Early

    • Obtain and validate Forms W-9 for all lenders, investors, and other potential interest recipients.
    • Flag entity type and exemption status.
  2. Review Interest Expense and Loan Accounts

    • Identify all accounts that involve interest payments (loan payable, notes payable, related-party loans).
    • Verify classification between principal and interest.
  3. Reconcile to Financial Institutions’ Reports

    • For clients with multiple bank or brokerage accounts, request year-end interest summaries.
    • Match 1099-INTs received with general ledger income accounts.
  4. Use Software Tools Wisely

    • Leverage 1099 e-filing platforms and accounting software with built-in validation.
    • Maintain a consistent coding system (e.g., vendor types for individuals vs. corporations).
  5. Document Edge Cases

    • For related-party loans, foreign recipients, or hybrid instruments, maintain clear workpapers explaining:
      • Why a 1099-INT was or was not issued
      • How interest was calculated and classified

Conclusion

Form 1099-INT may look straightforward, but for accountants, the real challenge lies in knowing who gets it, who doesn’t, and how to avoid common mistakes that lead to IRS mismatches and client frustration.

By:

  • Understanding which payors have filing obligations
  • Knowing which recipients are reportable vs. exempt
  • Carefully reviewing interest-bearing arrangements, especially business and related-party loans
  • Paying attention to thresholds, backup withholding, and entity classification

you can turn 1099-INT season from a last-minute scramble into a predictable, well-controlled process.

A bit of upfront diligence—especially around gathering W-9s, reviewing interest accounts, and addressing edge cases—goes a long way toward keeping both your clients and the IRS satisfied.
