Income can be earned through investments with capital in the form of capital gains, dividends, and interest. Each year, investors pay taxes on interest income from bonds, mutual funds, certificates of deposits (CDs), and demand deposit accounts. Some types of interest are fully taxable, while others are partially taxable.

Key Takeaways

Types of Interest Income

Interest is a part of the lending and investing industry. Lenders charge borrowers interest for using their capital as debt, such as loans and mortgages. The money these lenders earn in interest is referred to as interest income.

Investors deposit money into different investment vehicles to generate a return, usually as interest. This is referred to as interest income. The main types of interest income that an investor can earn include:

How Is Interest Taxed?

Regular taxable interest is taxed as ordinary income like an individual retirement account (IRA) or retirement plan distribution. Interest income is added to the taxpayer’s other ordinary income, such as wages or salary. This total income is used to calculate marginal tax rates.

This rule applies to interest that is both fully taxable at all levels and for interest that is taxable only at the federal level. Certain U.S. government obligations are taxable at the federal level only. Municipal bond interest is exempt from all taxation unless the alternative minimum tax (AMT) applies.

Taxpayers can exclude interest income redeemed from Series EE and Series I bonds issued after 1989 when used to pay for qualified higher educational expenses if they meet additional requirements for the Educational Savings Bond Program.

Marginal Tax Rates

The IRS sets the tax rates yearly based on inflation. When filing tax returns in 2024, taxpayers will apply 2023 marginal rates. When filing tax returns in 2025, marginal tax rates for 2024 apply.

Form 1099-INT and Form 1099-OID

Any institution that provides interest to an individual must send Form 1099-INT to all recipients by January 31 each year. Banks and investment firms must send out the form for interest over $10.This form shows the amount and type of interest paid during the year.

The 1099-INT form has several different boxes that list various types of interest income:

Taxpayers may also receive Form 1099-OID for taxable interest. Form 1099-OID reports original issue discount instruments; if a taxable bond or other debt instrument was issued at a discount, part of the original issue discount may be included each year as interest income. A Form 1099-OID is issued to taxpayers with taxable original issue discounts of $10 or more.

Taxpayers may also be named nominee recipients for taxes and receive a Form 1099 for interest in their name that belongs to someone else. The IRS has a set of instructions for reporting this income as part of Schedule B to Form 1040. You must also prepare a 1099 form to remit to the IRS unless the nomination came from a spouse.

Tax Returns

An accountant or tax preparation program or software will input all data from the forms (1099-INT, W2s, and others) to Form 1040, the standard Internal Revenue Service (IRS) form all individual taxpayers file every year.

Investors can also report all interest income received for the year on Part 1 of Schedule B: Interest and Ordinary Dividends of 1040. Any investor who receives a Form 1099-INT must be able to transcribe the information correctly on Schedule B of their tax return or IRS Form 1040.

Tax-Exempt Income

Types of tax-exempt income include:

Taxpayers must report taxable and non-taxable income on their tax return, even if they did not receive the appropriate 1099 forms.

Interest vs. Dividends

Interest income is generally taxed as ordinary income and is subject to the same tax rates as wages and salaries. Dividend income, such as qualified dividends, may be subject to long-term capital gains rates based on the taxpayer's income level and length of holding.

Dividends are paid out of a company's after-tax income. Interest is paid from pre-tax income. Companies that pay dividends face double taxation: once on their profits and again on the dividends they pay to shareholders. Alternatively, interest payments are tax-deductible for companies and more favorable as they can be used to lower tax liability.

Where Is Taxable Interest Reported to Taxpayers?

Taxable interest appears on Form 1099-INT. Box 1 of the form shows the interest income earned from the issuer.

What Is the Tax Rate on Interest Income?

The taxable rate on any interest income depends on the tax bracket or marginal tax rates in which a taxpayer falls. For a taxpayer in the 22% tax bracket, interest income is also taxed at this rate.

Do Taxpayers Have to Report Interest Income From a Personal Loan?

From the point of view of the borrower, personal loans are considered debt and not taxable income, which means borrowers don't have to report any interest to the IRS. However, if you lend money to family or friends in the form of a personal loan, any interest you earn is considered taxable income and must be reported to the IRS using Form 1099-INT.

The Bottom Line

Investors save money to generate dividends, capital gains, or interest. Regardless of what form it takes, this is all considered income. Taxpayers must report it along with any other income sources received during the tax year. Investors should be on the lookout for Form 1099-INT from financial institutions or investment firms after the end of January. This form shows how much interest was earned and what will be reported to the IRS.
