Yes, the interest your savings account earns is taxable income

The money you deposit into a savings account is yours and not taxed. But the interest the bank pays you on that money counts as income to the IRS, and you owe federal income tax on it. Most states tax it too. This applies to regular savings accounts, money market accounts, and certificates of deposit (CDs). The only exception is accounts specifically designed to avoid tax—like Roth IRAs or 529 education savings plans—but those have strict rules about what you can use the money for.

The bank reports what you earned to both you and the IRS on a form called a 1099-INT, which arrives by January 31 each year. You then report that interest on your tax return. If you owe taxes on the interest and don't report it, the IRS will catch the discrepancy because they receive the same 1099-INT the bank sent you.

Key Takeaways

  • Interest earned in a regular savings account is taxed as ordinary income at your federal tax rate, plus state income tax in most states.
  • Banks send you a 1099-INT form by January 31 reporting all interest paid during the previous year, and they send a copy to the IRS.
  • You must report savings account interest on your federal tax return, even if the amount is small or the bank did not send you a 1099-INT.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means you owe more tax on the earnings, but the after-tax return is often still better.
  • If you earn less than $10 in interest during the year, the bank may not send a 1099-INT, but you still owe tax on that income if you have any tax liability.

How the IRS taxes savings account interest

Savings account interest is treated as ordinary income, which means it is taxed at the same rate as your wages or salary. If you are in the 22 percent federal tax bracket, you pay 22 percent tax on your interest earnings. If you are in the 12 percent bracket, you pay 12 percent. The rate depends on your total income for the year, not just the interest.

On top of federal tax, most states also tax savings account interest as income. A handful of states—including Florida, Texas, Tennessee, and Wyoming—do not have state income tax at all. Others, like Illinois and Mississippi, exempt interest income from state tax but tax other kinds of income. Check your state's tax rules to know whether state tax applies to you.

The tax is due when you file your annual return, typically by April 15. You do not pay it to the bank; you pay it to the IRS (and your state, if applicable) when you file. The bank simply reports what you earned.

When banks report interest to the IRS

Your bank sends you a 1099-INT form by January 31 of the year after you earned the interest. This form shows the total interest paid to your account during the previous calendar year. The bank also sends an identical copy to the IRS, so the agency knows exactly how much interest you received.

Banks are required to send a 1099-INT if you earned $10 or more in interest during the year. If you earned less than $10, the bank may not send the form—but you still owe tax on that income. The IRS expects you to report all interest, whether or not you receive a 1099-INT.

If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You will receive one form from each institution. When you file your taxes, you add up all the interest from all your accounts and report the total.

The difference between high-yield and traditional savings accounts

A high-yield savings account pays significantly more interest than a traditional savings account—sometimes 4 to 5 percent annually, compared to 0.01 percent or less at many large banks. This means you earn more money, but you also owe more tax on those earnings.

The math still usually favors high-yield accounts. If you have $10,000 in a high-yield account earning 4.5 percent, you earn $450 per year. At a 22 percent federal tax rate plus, say, 5 percent state tax, you owe about $130 in taxes, leaving you $320 after tax. In a traditional account earning 0.01 percent, you earn $1, owe almost nothing in tax, and keep roughly $1. The high-yield account is still far ahead even after taxes.

The tax you owe on high-yield savings is still ordinary income tax, reported the same way on a 1099-INT. The only difference is the amount of interest, not the tax treatment.

How to report savings interest on your tax return

When you file your federal return, you report interest income on Schedule 1 (Form 1040), line 8. If you use tax software, the program will ask you to enter the interest amount and will place it in the correct location automatically. If you file by hand, you write the total interest from all your 1099-INT forms on that line.

The interest then flows into your total income, which determines your tax bracket and your overall tax liability. You do not pay tax on interest separately; it combines with all your other income.

If you file a state return, you report interest income there too, unless your state does not tax interest. The state form varies by state, but most ask for interest income on the first page or in an income section. Your state tax software or instructions will show you where.

What happens if you do not report savings interest

The IRS receives a copy of every 1099-INT your bank sends you. If you do not report the interest on your return, the IRS will notice the gap between what you reported and what the bank reported. This can trigger a notice asking you to explain the discrepancy or pay the tax you owe plus penalties and interest.

The penalty for not reporting income is usually 20 percent of the unpaid tax, plus interest that accrues daily. If the IRS determines the omission was intentional fraud rather than an honest mistake, the penalty can be as high as 75 percent. Even small amounts of unreported interest can start an audit.

If you made an honest mistake and forgot to report interest, you can file an amended return (Form 1040-X) to correct it. Filing an amendment before the IRS contacts you shows good faith and may reduce or eliminate penalties.

Tax-advantaged alternatives to regular savings accounts

If you want to save money without paying tax on the interest, certain accounts let you do that—though they come with restrictions on how and when you can use the money.

A Roth IRA lets you save for retirement and withdraw the interest tax-free in retirement, as long as you follow the rules (you must be at least 59½ and have held the account for at least five years). A 529 plan lets you save for education expenses and withdraw interest tax-free if you use the money for tuition, fees, or room and board. A Health Savings Account (HSA) lets you save for medical expenses and withdraw interest tax-free for may have access to medical costs.

These accounts do not eliminate taxes; they defer them or eliminate them only for specific uses. Money in a Roth IRA is still taxed when you earn it (you contribute after-tax dollars), but the growth is not. A 529 plan grows tax-free only if used for education. If you withdraw money for other reasons, you owe tax on the interest plus a 10 percent penalty in most cases.

A regular savings account has no restrictions—you can withdraw money anytime for any reason—but you pay tax on all the interest. The choice depends on whether you want flexibility or tax savings.

Frequently Asked Questions

Do I have to report savings interest if it is less than $10?

Yes. The bank does not have to send you a 1099-INT if you earned less than $10, but you still owe tax on that income. You must report all interest on your tax return, regardless of the amount. If you have multiple accounts that each earned less than $10 but together total more, add them all up and report the total.

What if I earned interest in a joint savings account?

The bank reports the full interest amount on a 1099-INT to whoever is listed as the account owner or primary holder. If the account is truly joint, you and the other owner should split the interest income proportionally based on your ownership stake and report your share on your own tax return. You may need to contact the bank to request a corrected 1099-INT if it does not reflect your actual share.

Can I deduct savings account fees from the interest I report?

No. You report the full interest amount the bank paid you, not the net after fees. Savings account fees are not deductible on your personal tax return. However, if you have a business savings account, you may be able to deduct business-related fees as a business expense.

Does a CD earn interest that gets taxed the same way?

Yes. A certificate of deposit (CD) earns interest that is taxed as ordinary income, reported on a 1099-INT, and handled the same way as savings account interest. The only difference is that you agree to leave the money in the CD for a set period (three months to five years, typically). If you withdraw early, you pay a penalty, but the interest itself is still taxable.

What if I moved money between savings accounts during the year?

Moving money between your own accounts does not create taxable income. Only the interest the bank pays you is taxable. If you transferred $5,000 from one savings account to another, that transfer is not income. But the interest earned on that $5,000 while it sat in either account is taxable.
