Savings Account Interest Is Taxable, But the Balance Itself Is Not
The money sitting in your savings account is not taxed based on how much is there. You do not pay income tax on the balance itself, whether it is $100 or $100,000. What gets taxed is the interest your bank pays you on that balance — and only if the interest reaches a certain threshold.
The threshold depends on your filing status and whether you are claimed as a dependent. For the 2024 tax year, you generally report interest income if you earned more than $1,300 in interest (or $2,600 if you are married filing jointly). Below that amount, you typically owe no federal income tax on the interest, though you may still need to file a return for other reasons.
State and local taxes work differently. Some states tax savings account interest at any amount; others do not tax it at all. Your state's rules are separate from the federal threshold, so you may owe state tax on interest even if you do not owe federal tax.
Key Takeaways
- Your savings account balance itself is never taxed — only the interest your bank pays you on that balance.
- Federal income tax on interest applies only if you earned more than $1,300 in interest during the year (or $2,600 if married filing jointly), though thresholds vary by filing status.
- State and local taxes on savings interest vary widely; some states tax all interest income, while others tax none.
- Your bank will send you a Form 1099-INT if you earned $10 or more in interest, which you use to report the income on your tax return.
- Interest earned in a Roth IRA or other retirement account is not taxed in the year it is earned, following different rules than regular savings accounts.
How Banks Report Your Interest Income
When your savings account earns interest, your bank tracks it. If you earned $10 or more in interest during the year, the bank sends you a Form 1099-INT by January 31 of the following year. This form shows the total interest paid to you and goes to the IRS as well.
You use the 1099-INT to report the interest on your federal tax return (Form 1040). Even if you earned less than $10 in interest, you still owe tax on it if it pushes you over the threshold for your filing status — you just will not receive a 1099-INT form. Keep your bank statements to prove the amount if you need to report small interest payments.
If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You add up all the interest from all your accounts when you file your return.
Federal Tax Thresholds by Filing Status
| Filing Status | Interest Income Threshold (2024) |
|---|---|
| Single | $1,300 |
| Married Filing Jointly | $2,600 |
| Married Filing Separately | $1,300 |
| Head of Household | $1,950 |
| may have access to Widow(er) | $2,600 |
These thresholds are the standard deduction amounts for 2024 and change each year. If your interest income is below your threshold and you have no other income, you may not need to file a federal return at all — though filing might still benefit you if you are due a refund from taxes withheld or from tax credits.
If you are claimed as a dependent on someone else's return, the threshold is lower. A dependent's standard deduction for 2024 is $1,300 (or their earned income plus $450, whichever is greater). This means a dependent with a savings account earning $1,301 in interest would need to file a return even though an independent person with the same income would not.
State and Local Taxes on Savings Interest
Nine states do not tax income at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividend income, but is phasing that out). If you live in one of these states, you owe no state income tax on your savings interest.
Every other state taxes interest income, though the rate and rules vary. Some states follow the federal threshold; others tax all interest regardless of amount. A few states offer deductions or exemptions for certain types of savings or for people over a certain age. Check your state's tax authority website or your most recent state tax return to see how your state treats savings interest.
Local taxes (city or county) rarely apply to savings interest, but some municipalities do tax income. If you live in a city that has an income tax — such as New York City, Columbus, or Philadelphia — that tax may apply to your interest income on top of state tax.
Interest Earned in Retirement Accounts Works Differently
If your savings is in a Roth IRA, a traditional IRA, or a 401(k), the interest earned inside the account is not taxed in the year it is earned. This is one of the main advantages of retirement accounts: the money grows tax-free (or tax-deferred) until you withdraw it.
With a Roth IRA, you never pay tax on the interest, even when you withdraw the money in retirement. With a traditional IRA or 401(k), you pay tax on the interest when you withdraw it, not when it is earned. High-yield savings accounts held outside retirement accounts do not have this benefit — you pay tax on the interest every year.
If you are trying to save money tax-efficiently, moving funds into a Roth IRA (if you meet income limits) or a 401(k) (if your employer offers one) can shield interest from annual taxation. Consult a tax professional about whether this makes sense for your situation.
What Happens If You Do Not Report Interest Income
The IRS receives a copy of every 1099-INT your bank sends you. If you do not report the interest on your tax return, the IRS will notice the discrepancy and may send you a notice asking for the missing income and any tax owed, plus penalties and interest.
Even small amounts matter. If you earned $50 in interest and did not report it, the IRS can still pursue it. The penalty for not reporting income is typically 20% of the unpaid tax, plus interest that accrues daily. It is far simpler to report the interest when you file.
If you made an honest mistake and did not report interest in a prior year, you can file an amended return (Form 1040-X) for that year. The IRS generally looks back three years for routine audits, though they can go back longer if they suspect fraud.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
You will not receive a 1099-INT if you earned less than $10, but you still owe tax on it if it pushes your total income over your filing threshold. Keep your bank statements and report the interest on your return. The IRS does not ignore small amounts.
What if I have savings in multiple banks?
Each bank sends its own 1099-INT. Add up all the interest from all your accounts and report the total on your tax return. If the combined interest exceeds your threshold, you must file a return.
Does money I transfer into my savings account count as income?
No. Transfers of your own money — from checking, from a paycheck, from selling something — are not income and are not taxed. Only the interest the bank pays you is taxed.
Can I avoid taxes by keeping my savings under a certain amount?
The amount in your account does not matter for taxes. A $50,000 balance earning 4% interest ($2,000 per year) is taxable, while a $1,000 balance earning 4% interest ($40 per year) is not — because the tax is on the interest, not the balance. You cannot reduce your tax by moving money around.
What if my state does not tax income but I live in a city that does?
You would owe city tax on your interest but not state tax. File both your state return (if required) and your city return, reporting the interest on whichever forms apply. Check your city's tax authority for the specific rules.
