You don't pay tax on the money itself, only on the interest it earns

The balance sitting in your savings account is not taxed. You can deposit $10,000 and leave it there untouched without owing anything to the IRS. The tax comes only when your bank pays you interest — the money the bank gives you for letting them use your deposit.

If your account earns $50 in interest over a year, that $50 is taxable income. The original $10,000 stays yours, tax-free. This matters because many people confuse the two and worry they'll owe tax on their entire balance, which is not how it works.

The tax rate on interest depends on your overall income and tax bracket. Interest counts as ordinary income, so it's taxed at the same rate as wages or salary — anywhere from 10% to 37% depending on how much you earn in total.

Key Takeaways

  • Your savings account balance itself is never taxed; only the interest your bank pays you is taxable income.
  • Banks report interest to the IRS on a 1099-INT form when you earn $10 or more in a calendar year.
  • Interest is taxed as ordinary income at your regular tax rate, which varies based on your total yearly earnings.
  • You may owe estimated tax payments if interest and other income push you over a certain threshold, though most people handle this through regular withholding.

How banks report your interest to the IRS

Your bank sends you a Form 1099-INT by January 31 each year if you earned $10 or more in interest during the previous calendar year. This form lists the total interest paid to your account. The bank also sends a copy to the IRS, so the agency already knows what you earned.

You report this interest on your tax return, usually on Schedule 1 (Form 1040) or directly on the 1040 itself, depending on the year and your situation. If you earned interest but didn't receive a 1099-INT because it was under $10, you still report it — the IRS expects you to count all interest income.

If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You add them all together when you file. Some people use a spreadsheet or tax software to track this; others wait for all their forms to arrive and add them up then.

When interest is small enough that you might owe nothing

Even if you earn interest, you may not owe any tax on it if your total income is low enough. The standard deduction — the amount of income you can earn before owing federal tax — varies by age and filing status. For 2024, a single person under 65 has a standard deduction of $14,600. If your total income, including interest, is below that, you owe no federal income tax.

This means someone with $500 in a savings account earning $15 in interest, plus $10,000 in wages, owes no federal tax because their total income is $10,015, well below the standard deduction. The interest is still reported on a 1099-INT, but it doesn't result in a tax bill.

State income tax works differently depending on where you live. Some states don't tax interest at all. Others tax it the same way the federal government does. A few have special rules for retirement accounts or accounts held by people over a certain age. Check your state's tax authority website or ask a tax preparer about your state's rules.

High-yield savings accounts and interest tax

High-yield savings accounts pay more interest than traditional savings accounts — sometimes 4% or 5% annually instead of 0.01%. This means you earn more interest, which also means you owe more tax on that interest. The tax treatment is identical; the only difference is the amount.

If you have $50,000 in a high-yield account earning 5%, you'll earn roughly $2,500 in interest over a year. That $2,500 is taxable income. If you're in the 22% tax bracket, you'll owe about $550 in federal tax on that interest. With a traditional savings account earning 0.01%, you'd earn $5 and owe roughly $1 in tax.

Some people move money to high-yield accounts specifically because the interest outweighs the tax. Others stay in lower-yield accounts to minimize tax. The math depends on your tax bracket and how much you have saved. A tax preparer or accountant can help you think through whether the higher interest is worth it for your situation.

Money market accounts and CDs are taxed the same way

Money market accounts and certificates of deposit (CDs) earn interest just like savings accounts do. The interest is reported on a 1099-INT and taxed as ordinary income. The only difference is how much interest they typically pay — CDs often pay more, especially if you lock your money away for a longer period.

If you have a CD that matures and you don't roll it into a new CD, the interest earned is still taxable in the year you earned it, even if you don't touch the money. Some CDs pay interest monthly or quarterly; others pay it all at maturity. Either way, it's taxable in the year earned.

One exception: if you cash out a CD early, you may owe an early withdrawal penalty. That penalty is not tax-deductible, so you lose money twice — once to the penalty and again to tax on the interest you earned.

What happens if you don't report interest income

The IRS receives a copy of every 1099-INT your bank sends you. If you don't report the interest on your tax return, the IRS will notice the discrepancy when it matches your return against the forms it received. This can trigger a notice asking you to explain the difference or pay the tax you owe plus penalties and interest.

The penalty for not reporting income is usually 20% of the unpaid tax, plus interest that accrues daily. If the IRS determines the omission was intentional fraud rather than a mistake, the penalty can be as high as 75%. For most people, it's an honest mistake — they didn't realize the interest was taxable or didn't receive the 1099-INT — and the IRS handles it as a correction rather than prosecution.

If you realize you missed reporting interest in a prior year, you can file an amended return (Form 1040-X) for that year. This is usually faster and less costly than waiting for the IRS to contact you.

Frequently Asked Questions

Do I have to pay tax on interest if I'm retired?

Interest is taxable regardless of your age or employment status. However, the standard deduction is higher for people 65 and older — $17,550 for a single filer in 2024, compared to $14,600 for younger filers. This means you can earn more interest before owing tax. Some states also offer tax breaks on interest for retirees; check your state's rules.

What if I earned less than $10 in interest?

You won't receive a 1099-INT, but you still report the interest on your tax return if you file one. The IRS expects all interest income to be reported, regardless of amount. If your total income is below the standard deduction, you may not owe tax, but you should still report it accurately.

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

No. Savings account fees are not deductible. You report the full interest amount on your tax return and pay tax on it, even if fees reduced your net earnings. For example, if you earned $100 in interest but paid $5 in fees, you report $100 as taxable income.

Is interest from a joint savings account split between both owners for tax purposes?

Not automatically. The bank reports the full interest amount on a 1099-INT to whoever is listed as the account owner or primary account holder. If the account is truly joint and both people contributed equally, you may need to split the interest on your individual tax returns. This requires coordination between the account holders and sometimes a conversation with a tax preparer.

Do I owe tax on interest if I'm a dependent on someone else's return?

Yes, you owe tax on your interest income. However, your standard deduction may be lower than an independent filer's. For 2024, a dependent's standard deduction is the greater of $1,300 or their earned income plus $450, up to the standard deduction for a single filer. If your interest income is below that threshold, you owe no tax.
