Savings account interest is taxable income
Yes, you must pay federal income tax on the interest your savings account earns. The IRS treats it as ordinary income, taxed at your regular income tax rate — not at a lower capital gains rate. If your savings account earned $50 in interest last year, that $50 counts as income you owe tax on, just like wages or a bonus.
Your bank reports this interest to the IRS on a Form 1099-INT (Interest Income). You receive a copy, and so does the IRS. When you file your tax return, you add that interest to your other income and pay tax on the total. The amount of tax you owe depends on your overall income and your tax bracket.
State and local income taxes also apply to savings interest in most states. If you live in a state with an income tax, you will owe state tax on the interest as well. A few states — including Florida, Texas, and Wyoming — have no state income tax, so residents there owe only federal tax.
Key Takeaways
- Savings account interest is taxed as ordinary income at your federal tax rate, not at a lower rate.
- Your bank sends you a Form 1099-INT if you earned $10 or more in interest during the year, and sends a copy to the IRS.
- You must report all interest income on your federal tax return, even if you do not receive a 1099-INT.
- Most states tax savings interest as well, unless you live in a state with no income tax.
- High-yield savings accounts earn more interest, which means you owe more tax — but the after-tax return is still usually higher than traditional savings accounts.
When you receive a Form 1099-INT and what it means
Your bank issues a Form 1099-INT when you earn $10 or more in interest during a calendar year. You will receive it by January 31 of the following year. The form shows the total interest paid to you and breaks it down by account if you have multiple accounts at the same bank.
If you earned less than $10, your bank may not send a 1099-INT, but you still owe tax on that interest. You must report it on your return even without the form. The IRS has a record of what your bank paid you, so omitting it creates a mismatch that can trigger a notice.
If you have accounts at multiple banks, you will receive a separate 1099-INT from each one. Add all the interest together when you file your return. Some people have accounts at five or six institutions and receive five or six forms — you need to track and report all of them.
How much tax you actually owe on savings interest
The tax you owe depends on your total income and your tax bracket. If you earn $50 in interest and you are in the 22% federal tax bracket, you owe roughly $11 in federal tax on that interest. If you are in the 12% bracket, you owe roughly $6. If you are in the 37% bracket (the highest), you owe roughly $18.50.
Your state tax works the same way. If your state has a 5% income tax and you earn $50 in interest, you owe roughly $2.50 in state tax. The total tax on that $50 could range from $6 (in a low-bracket, no-state-tax situation) to $20 or more (in a high-bracket, high-state-tax situation).
This is why high-yield savings accounts matter: they earn 4% to 5% interest instead of 0.01%, but the extra earnings are also taxable. A $10,000 balance earning 4.5% generates $450 in taxable interest per year. In a 22% federal bracket plus a 5% state tax, you owe roughly $130 in tax, leaving you with $320 in after-tax gain. That is still far better than earning $1 in interest and owing $0.22 in tax.
Reporting 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, it will ask you for the total interest from all sources. If you file by hand, you add up all your 1099-INT forms and write the total on that line.
The interest then flows into your adjusted gross income (AGI), which affects your tax bracket and may affect other deductions or credits you can claim. Higher interest income can push you into a higher bracket or reduce your may be able to access for certain tax breaks.
For state taxes, most states have a similar line on their return where you report interest income. Some states follow federal rules exactly; others have different thresholds or rules. Check your state tax authority's website or your state return instructions to see where to report it.
Interest from CDs, money market accounts, and other savings products
All interest-bearing savings products are taxed the same way: CDs, money market accounts, savings accounts, and even interest from checking accounts. If it earns interest, it is taxable income. A CD that matures and pays you $200 in interest is taxed just like $200 from a regular savings account.
The bank or financial institution holding the account issues the 1099-INT, regardless of the account type. If you have a CD at one bank and a savings account at another, you will receive two separate forms and must report both.
Treasury bills, Treasury notes, and Treasury bonds also generate taxable interest, reported on a different form (Form 1099-INT or 1099-OID depending on the type). The interest is taxable at the federal level but exempt from state and local income tax.
What happens if you do not report interest income
The IRS receives a copy of every 1099-INT your bank sends to you. If you do not report the interest on your return, the IRS will notice the mismatch between what you reported and what the bank reported. This triggers an automated notice asking you to explain the difference or pay the tax owed.
If you ignore the notice, the IRS can assess the tax, plus penalties and interest. The penalty for not reporting income is typically 20% of the underpaid tax, plus interest that compounds daily. On $50 in unreported interest, that could add up to $15 or $20 in penalties alone.
Reporting the interest takes minutes and costs nothing. Not reporting it can cost far more in penalties than the tax itself would have been.
Tax-advantaged accounts that avoid or defer interest tax
Some accounts let you earn interest without paying tax on it immediately. A Roth IRA or Roth 401(k) allows interest to grow tax-free, and you pay no tax when you withdraw it in retirement (as long as you follow the rules). A traditional IRA or 401(k) defers the tax until you withdraw the money.
A 529 college savings plan allows interest to grow tax-free if you use the money for education expenses. A Health Savings Account (HSA) works the same way for medical expenses.
These accounts have contribution limits and withdrawal rules, so they are not a free pass to avoid tax on all your savings. But if you have money set aside for retirement or a known future expense, putting it in one of these accounts can save you significant tax on the interest it earns.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
Yes. Your bank does not have to send you a 1099-INT if you earned less than $10, but you still owe tax on that interest and must report it on your return. The IRS expects you to report all income, regardless of whether you receive a form.
What if my bank sent me a 1099-INT with the wrong amount?
Contact your bank immediately and ask them to issue a corrected form (a 1099-INT with a "CORRECTED" box checked). Once you receive the corrected form, file an amended return if you have already filed. The IRS will match the corrected form to your amended return.
Can I deduct the tax I pay on savings interest?
No. Interest income is added to your taxable income, but you cannot deduct the tax you owe on it as a separate expense. The tax is calculated as part of your overall return based on your total income and bracket.
Is interest from a joint savings account taxed differently?
No. The interest is still taxable income. If the account is held jointly and both owners contributed equally, you may each report half the interest, but this depends on how the account is titled and your state's rules. Consult a tax professional if you are unsure how to split it.
Do I owe tax on interest if I moved to a different state mid-year?
Yes, and you may owe tax to both states. You typically file a part-year resident return in the state you left and a part-year resident return in the state you moved to. Each state taxes the interest earned while you were a resident there. Your new state's tax authority can tell you how to file.
