What actually reduces your tax bill on savings interest

You cannot avoid taxes on savings account interest entirely if you earn it — the IRS requires you to report all interest income. But you can reduce the amount of interest you earn in the first place, which lowers your tax burden. The main strategies are moving money to accounts that earn less taxable interest, using tax-advantaged accounts where interest grows tax-free, and timing withdrawals to stay below income thresholds that trigger higher tax rates.

The most direct route is opening a Roth IRA or Roth 401(k), where interest and investment gains are never taxed as long as you follow withdrawal rules. If you cannot use those accounts or have already maxed them out, a Health Savings Account (HSA) offers the same tax-free growth on interest if you use it for medical expenses. For money you need to access sooner, I Bonds (Series I Savings Bonds) defer federal tax until you cash them, and state tax never applies.

Key Takeaways

  • Roth IRAs and Roth 401(k)s let interest grow completely tax-free, but you cannot withdraw the money before age 59½ without penalties unless you meet specific exceptions.
  • Health Savings Accounts work like Roth accounts for interest if you spend the money on medical bills, and you can withdraw it tax-free for that purpose at any age.
  • I Bonds delay federal tax until you cash them and never trigger state income tax, making them useful for money you will not need for at least one year.
  • Keeping your total income below certain thresholds can lower your tax bracket and reduce the rate at which your interest is taxed.
  • Regular savings accounts and money market accounts earn taxable interest no matter what you do, so they are the wrong place for money you want to shelter from tax.

Tax-free accounts where interest does not count as income

A Roth IRA is the most common way to earn interest without paying tax on it. You contribute money you have already paid income tax on, and then all interest, dividends, and investment gains stay inside the account tax-free. When you withdraw money in retirement (age 59½ or later), you owe nothing to the IRS. The catch is you cannot touch the money before 59½ without a 10% penalty, except in narrow cases like a first-time home purchase (up to $10,000 lifetime) or a Roth conversion exception.

If your employer offers a Roth 401(k), it works the same way — contributions are after-tax, and all growth is tax-free in retirement. The withdrawal rules are identical to a Roth IRA. A Health Savings Account is less known but often more flexible: you can earn interest on the balance, and that interest is never taxed as long as you spend the money on medical expenses (doctor visits, prescriptions, dental work, vision care, and many other health costs). You can withdraw HSA money tax-free for medical bills at any age, and you can even reimburse yourself for old medical expenses years later.

All three accounts have annual contribution limits. For 2024, a Roth IRA caps at $7,000 per year ($8,000 if you are 50 or older). A Roth 401(k) limit is $23,500 ($31,000 if 50 or older). An HSA limit depends on your health plan type but ranges from $4,150 to $8,300 per year. If you have already maxed these out, you cannot shelter more interest this way.

I Bonds: federal tax deferral with no state tax

I Bonds (Series I Savings Bonds) are issued by the U.S. Treasury and earn interest that combines a fixed rate plus an inflation rate that adjusts every six months. The federal tax on that interest does not come due until you cash the bond — you can hold it for decades and pay nothing until then. State and local income tax never applies to I Bond interest at all.

The tradeoff is that you must hold an I Bond for at least one year before you can cash it, and if you cash it before five years, you lose the last three months of interest as a penalty. After five years, you can cash it anytime with no penalty. You can buy up to $10,000 per person per calendar year through TreasuryDirect.gov, and an additional $5,000 using your tax refund. Interest rates change every six months (May and November), so the rate you lock in depends on when you buy.

I Bonds are useful for money you know you will not need for at least one year and can afford to leave untouched for longer. They are not a high-yield option — current rates are lower than many high-yield savings accounts — but the tax deferral and state tax exemption make them worth considering for a portion of your savings.

Keeping income below tax bracket thresholds

Your interest income counts toward your total income for the year, and your total income determines your tax bracket. If you can keep your total income below certain thresholds, you may drop into a lower bracket and pay a lower tax rate on everything, including your interest.

For example, in 2024, a single filer pays 12% federal tax on income between $11,601 and $47,150, and 22% on income between $47,151 and $100,525. If your interest income pushes you from $47,100 to $47,200, that extra $100 of interest is taxed at 22% instead of 12%. Conversely, if you can keep your total income at $47,150 or below, all your interest stays in the 12% bracket.

This strategy works best if you have some control over your income — for instance, if you are self-employed and can time invoices, or if you are retired and can choose when to take distributions from retirement accounts. For most people with a regular paycheck, interest income is small enough that it does not push them into a higher bracket. Check your expected total income for the year and see where it falls on the IRS tax tables; if you are close to a bracket edge, reducing interest income by moving money to a tax-free account may save you more than the interest itself would earn.

Why high-yield savings accounts still mean taxes

A high-yield savings account earns more interest than a regular savings account — sometimes 4% to 5% annually — but every dollar of that interest is taxable income. The bank will send you a 1099-INT form at the end of the year reporting all interest earned, and you must report it on your tax return. There is no way around it: if the money sits in a taxable account and earns interest, you owe tax on it.

High-yield savings accounts are useful for emergency funds and money you need to access quickly, because they are liquid and FDIC-insured. But they should not be your strategy for sheltering savings from tax. If you have money you do not need for several years, a Roth IRA or I Bonds will save you far more in taxes than a high-yield savings account will earn in interest.

Money market accounts and CDs: still taxable

Money market accounts and Certificates of Deposit (CDs) work the same way as savings accounts from a tax perspective: all interest is taxable income, reported on a 1099-INT, and owed to the IRS. A money market account may offer slightly higher interest than a savings account, and a CD locks in a rate for a set term (three months to five years), but neither one reduces your tax bill.

The only exception is if you open a Roth IRA CD or an HSA CD — some banks offer these products, and the interest inside them grows tax-free. But you are limited by the annual contribution caps for those accounts, so this only works for a portion of your savings.

Reporting interest income correctly on your tax return

If you earn more than $10 in interest from any single account during the year, the bank or financial institution must send you a Form 1099-INT by January 31. You receive one copy and the IRS receives another. You must report all interest income on your tax return, even if you do not receive a 1099-INT (for instance, if you earned less than $10 from a particular account).

Interest goes on Schedule B (Interest and Ordinary Dividends) if you file a full tax return, or directly on your 1040 if you use the short form. If you have interest from multiple accounts, add it all together and report the total. The IRS matches the 1099-INT forms they receive from banks against your return, so underreporting interest can trigger an audit notice.

If you have moved money to tax-free accounts like a Roth IRA or I Bonds, that interest does not appear on a 1099-INT and does not get reported on your tax return. That is the whole point — it is not taxable income.

Frequently Asked Questions

Can I put money in a Roth IRA just to avoid taxes on interest?

Yes, but only up to the annual limit ($7,000 in 2024, or $8,000 if you are 50 or older). You also must have earned income at least equal to what you contribute. If you earn $5,000 that year, you can only contribute $5,000 to a Roth IRA, even if you have more savings. Once you hit the limit, any additional savings must go elsewhere.

What happens if I withdraw money from a Roth IRA before age 59½?

You can withdraw your contributions (the money you put in) anytime tax-free. But if you withdraw earnings (the interest and gains), you owe income tax on them plus a 10% penalty. Exceptions exist for first-time home purchases (up to $10,000), disability, and a few other cases. Check IRS rules before withdrawing.

Do I Bonds earn enough interest to be worth the one-year lock-in?

That depends on current rates and your tax bracket. I Bonds currently earn less than many high-yield savings accounts, but the tax deferral and state tax exemption can make up the difference if you are in a high tax bracket. Use a calculator to compare the after-tax return of an I Bond against a taxable savings account at your tax rate.

Can I report interest income as zero if I earned less than $10?

You must report all interest income, even if it is $1. The bank may not send you a 1099-INT if you earned less than $10, but you still owe tax on it. The IRS expects you to track and report all interest yourself.

What if I have interest from accounts in my child's name?

Your child must report the interest on their own tax return if they earned it. Interest income is taxable to whoever earned it, regardless of age. If your child earned less than the standard deduction for the year, they may owe no tax, but they still need to file a return to report it.
