Form 1099-INT Interest Income (2012): A Complete Guide

What Form 1099-INT Is For

Form 1099-INT is an informational tax document that reports interest income you earned during the 2012 tax year. If you received at least $10 in interest from banks, savings and loans, credit unions, or other financial institutions, they're required to send you this form. Think of it as a receipt showing how much interest income the IRS knows you earned.

The form reports various types of interest, including regular interest from savings accounts and certificates of deposit (CDs), interest on U.S. Savings Bonds and Treasury obligations, and tax-exempt interest from municipal bonds. Financial institutions use this form to tell both you and the IRS about taxable interest they paid you during the year. The threshold increases to $600 for interest paid in the course of business activities, such as delayed death benefits from life insurance companies or interest on state or federal tax refunds.

In 2012, there were notable updates: exempt-interest dividends from mutual funds were moved to Form 1099-DIV instead of Form 1099-INT, and state tax withholding boxes were added to the form. IRS.gov

When You’d Use Form 1099-INT

Late/Amended

You'll receive Form 1099-INT from financial institutions by January 31, 2013, for the 2012 tax year. If you receive a corrected Form 1099-INT after you've already filed your tax return, you may need to file Form 1040X (Amended U.S. Individual Income Tax Return) to correct your previously filed return.

Common situations requiring late or amended filing include receiving a corrected 1099-INT showing a different interest amount than what you originally reported, discovering you forgot to report interest from an account, or finding that you reported interest on the wrong line of your tax return. If the IRS catches math errors or you simply forgot to attach a form, they'll often correct these automatically, and you won't need to file an amended return. However, if the error affects your taxable income or the amount of tax you owe, you should file Form 1040X.

Generally, you have three years from the original filing deadline to file an amended return and claim a refund. For the 2012 tax year (filed in 2013), you would have until April 15, 2016, to amend unless extensions apply. IRS.gov

Key Rules for 2012

The most important rule is simple: if you received at least $10 in taxable interest during 2012, you must report it on your tax return, regardless of whether you received a Form 1099-INT. All taxable interest goes on Line 8a of Form 1040, and if your total taxable interest exceeds $1,500, you must also complete and attach Schedule B (Form 1040), Interest and Ordinary Dividends, listing each payer and the amount received.

For 2012, the backup withholding rate was 28%. This means if you failed to provide your Social Security number or taxpayer identification number (TIN) to your bank, they would have withheld 28% of your interest and sent it to the IRS. You'll see this amount in Box 4 of your Form 1099-INT and can claim it as a credit on your return.

Tax-exempt interest from municipal bonds isn't taxable at the federal level but must still be reported on Line 8b of Form 1040. Some tax-exempt interest from "specified private activity bonds" may be subject to Alternative Minimum Tax (AMT). Interest on U.S. Savings Bonds and Treasury obligations is exempt from state and local taxes but is federally taxable. Early withdrawal penalties from CDs are deductible from your gross income even if they exceed your interest income for the year. IRS.gov

Step-by-Step (High Level)

Step 1: Gather Your Forms.

Collect all Form 1099-INT statements you received by late January or early February. Don't forget about interest from accounts you closed during the year.

Step 2: Review Each Box.

Box 1 shows your taxable interest income—this is the main number you'll report. Box 2 shows early withdrawal penalties you can deduct. Box 3 reports interest on U.S. Savings Bonds and Treasury obligations (also taxable but reported separately). Box 4 shows any backup withholding. Box 8 reports tax-exempt interest from municipal bonds.

Step 3: Total Your Interest.

Add up all the amounts from Box 1 across all your 1099-INT forms. This is your total taxable interest for the year.

Step 4: Report on Your Tax Return.

If your total taxable interest is $1,500 or less, simply enter the total on Line 8a of Form 1040 or 1040A. If it exceeds $1,500, you must complete Schedule B, listing each payer and amount, then transfer the total to Line 8a. Report tax-exempt interest on Line 8b even though it's not taxable.

Step 5: Claim Deductions and Credits.

If Box 2 shows an early withdrawal penalty, deduct it on Line 30 of Form 1040 (you cannot use Form 1040EZ or 1040A if you have this deduction). If Box 4 shows backup withholding, include it with your federal tax withheld on Line 64 of Form 1040. IRS.gov

Common Mistakes and How to Avoid Them

Forgetting Small Amounts

Many people forget to report interest from small accounts or accounts they closed mid-year. Even if you didn't receive a 1099-INT because the interest was under $10, it's still taxable. Keep your own records.

Overlooking Multiple Forms

If you have accounts at several banks, you'll receive multiple 1099-INT forms. Double-check that you've accounted for every form—it's easy to misplace one.

Reporting Tax-Exempt Interest as Taxable

Box 8 interest from municipal bonds goes on Line 8b, not Line 8a. While it doesn't increase your tax, it must still be reported because it affects certain calculations and benefits.

Not Filing Schedule B When Required

If your interest exceeds $1,500, you must attach Schedule B. Simply putting the total on Line 8a isn't sufficient and could trigger IRS correspondence.

Ignoring Backup Withholding

If Box 4 has an amount, make sure to include it with your other federal withholding. This is tax you already paid, and forgetting it means you'll overpay.

Mishandling Early Withdrawal Penalties

Box 2 amounts are deductible "above the line" on Line 30 of Form 1040. Don't subtract this from Box 1 when reporting your interest—report the full Box 1 amount and take the penalty as a separate deduction.

Missing Nominee Situations

If you received a 1099-INT for an account you hold jointly or for someone else, you need to file a nominee 1099-INT showing the other person's share and only report your portion on your return. IRS.gov

What Happens After You File

Once you file your 2012 tax return reporting your interest income, the IRS's computers match the 1099-INT forms they received from your financial institutions against what you reported. If everything matches and your return is error-free, your return processes normally, and you'll receive any refund due typically within 21 days of e-filing or six weeks of mailing a paper return.

If there's a discrepancy—such as a missing 1099-INT or a reporting error—you'll receive a CP2000 notice, usually 12-18 months after filing. This "Proposed Changes to Your Tax Return" notice isn't a bill but an inquiry explaining the difference between what you reported and what the IRS received. You can respond by agreeing with the changes, providing additional information, or disputing the notice with documentation.

If you discover an error after filing, you can file Form 1040X to amend your return. Amended returns take considerably longer to process—typically 8-12 weeks for electronically filed returns and up to 16 weeks for paper returns. If your amendment results in additional tax owed, file as soon as possible to minimize interest charges. If it results in a refund, you have three years from the original deadline to claim it.

The statute of limitations for IRS audits is generally three years from the filing date, so keep your 1099-INT forms and supporting documentation for at least that long. IRS.gov

FAQs

What if I never received my Form 1099-INT?

First, contact your bank or financial institution—they should have mailed it by January 31, 2013. You can also check online banking portals where forms are often available electronically. If you still can't get it, you must estimate the amount based on your monthly statements and report it anyway. All interest income is taxable whether or not you received a form.

Do I have to report interest under $10?

Yes. While financial institutions aren't required to send a 1099-INT for amounts under $10, you're still legally required to report all interest income, no matter how small. Keep your own records throughout the year.

Is interest from my savings bond taxable?

Yes, interest from U.S. Savings Bonds is federally taxable (reported in Box 3) but exempt from state and local income taxes. You can choose to report savings bond interest annually or wait until redemption or final maturity. IRS.gov

What's the difference between Box 1 and Box 8 interest?

Box 1 shows taxable interest that increases your federal tax bill. Box 8 shows tax-exempt interest, typically from municipal bonds, which doesn't increase your federal tax but must still be reported because it can affect other calculations, such as determining taxable Social Security benefits or education credits. IRS.gov

I paid a penalty for withdrawing my CD early. How do I claim this?

The penalty amount appears in Box 2 of Form 1099-INT. Report the full interest from Box 1 on your return, then take the penalty as an "above-the-line" deduction on Line 30 of Form 1040. This reduces your adjusted gross income. You cannot use Form 1040EZ or 1040A if you have an early withdrawal penalty to deduct.

What is backup withholding and why was I subject to it?

Backup withholding at 28% happens when you fail to provide your correct Social Security number or taxpayer identification number to your bank, or if the IRS notifies the institution that you underreported interest income previously. The withheld amount appears in Box 4 and counts as federal tax you've already paid—include it with your other withholding on Line 64 of Form 1040.

Do I need to file Schedule B?

You must file Schedule B (Form 1040) if your total taxable interest or ordinary dividends exceed $1,500, if you received interest or dividends as a nominee for the actual owner, or if you had a foreign account. Schedule B requires you to list each payer's name and amount. IRS.gov
