Form 1099-INT Checklist | Tax Year 2021
Purpose
Form 1099-INT reports taxable and tax-exempt interest income paid during the 2021 calendar year. Financial institutions, brokers, and other payers must file this form for recipients who received at least $10 in reportable interest, or $600 or more of interest paid in the course of trade or business. The form ensures proper reporting of interest income to both recipients and the Internal Revenue Service.
Preparation Steps
Step 1: Verify Recipient Taxpayer Identification Numbers
Confirm the accuracy of each recipient’s TIN against IRS records before filing. If a TIN mismatch is detected, you must request a corrected Form W-9 from the recipient. If the recipient fails to provide a correct TIN or you receive an IRS notice of an incorrect TIN, backup withholding at a rate of 24% applies to subsequent payments. Maintain documentation of all TIN verification efforts and recipient communications to support your filing position.
Step 2: Categorize Interest Income by Type
Separate all interest payments into the appropriate reporting categories. Taxable interest from bank deposits, corporate bonds, and similar obligations goes in Box 1. U.S. Savings Bond and Treasury obligation interest belongs in Box 3. Tax-exempt interest from municipal bonds and similar obligations must be reported in Box 8. For specified private activity bonds, report the interest in both Box 8 and Box 9. Ensure no amount is double-counted across categories, and verify that tax-exempt interest is not included in taxable interest totals.
Step 3: Calculate and Report Early Withdrawal Penalties
Identify any interest or principal forfeited due to early withdrawal of time deposits, such as certificates of deposit. Report the forfeiture amount separately in Box 2. This amount represents an above-the-line deduction available to recipients when calculating adjusted gross income. Do not reduce the interest amount reported in Box 1 by the penalty amount. Follow IRS Revenue Rulings 75-20 and 75-21 for detailed guidance on calculating the deductible forfeiture amount.
Step 4: Report U.S. Savings Bond and Treasury Interest
Enter interest earned on U.S. Savings Bonds, Treasury bills, Treasury bonds, and Treasury notes in Box 3. This interest is exempt from state and local income taxes but remains subject to federal taxation. Do not include these amounts in Box 1. If you make a payment on a U.S. Savings Bond or other Treasury obligation, enter your name, address, and TIN on the form, not those of the U.S. Treasury Department or Bureau of the Fiscal Service.
Step 5: Apply Backup Withholding When Required
Withhold federal income tax at the 24% backup withholding rate if the recipient did not provide a TIN, furnished an incorrect TIN, or you received IRS notification of TIN issues. Backup withholding also applies if the IRS notifies you that the recipient underreported interest or dividend income. Apply the withholding to amounts reportable in Box 1, Box 3, and Box 8, but limit withholding to actual cash payments made. Report the total backup withholding amount in Box 4.
Step 6: Handle Bond Premium Amortization for Covered Securities
For taxable covered securities acquired at a premium, determine whether the recipient elected to amortize bond premium under Section 171. Unless you received written notification from the recipient electing out of premium amortization per Regulations section 1.6045-1(n)(5), you must report premium amortization. You may report either a net interest amount in Box 1 with the premium already deducted, or report gross interest in Box 1 and the premium amortization amount in Box 11. For tax-exempt covered securities acquired at a premium, always report premium amortization in Box 13 or as a net amount in Box 8.
Step 7: Report Tax-Exempt Interest Accurately
Enter all tax-exempt interest of $10 or more in Box 8. This includes interest from obligations issued by states, the District of Columbia, U.S. possessions, Indian tribal governments, or their political subdivisions. Include any accrued qualified stated interest on tax-exempt bonds sold between interest dates. Tax-exempt interest may still be subject to backup withholding if TIN requirements are not met. Recipients must report this amount on their tax returns even though it is not taxable for regular income tax purposes.
Step 8: Identify Specified Private Activity Bond Interest
Report interest from specified private activity bonds separately in Box 9. This interest is subject to the Alternative Minimum Tax calculation. Specified private activity bonds are generally private activity bonds as defined in Section 141 that were issued after August 7, 1986. The amount reported in Box 9 should also be included in the total tax-exempt interest reported in Box 8. Recipients need this information to complete Form 6251 for AMT calculations.
Step 9: Report Tax Credit Bond Interest as Taxable Income
Report tax credits allowed from qualified tax credit bonds as taxable interest income in Box 1. These bonds include clean renewable energy bonds, new clean renewable energy bonds, qualified energy conservation bonds, qualified zone academy bonds, qualified school construction bonds, and Build America bonds with the tax credit option. Credits are treated as paid on credit allowance dates of March 15, June 15, September 15, and December 15. Recipients must include these credit amounts in their interest income and separately claim the credits on Form 8912.
Step 10: Report Market Discount for Covered Securities
For covered securities acquired with a market discount, report the accrued market discount in Box 10 if the recipient notified you in writing of a Section 1278(b) election to include the market discount in income as it accrues. Unless the recipient notified you otherwise, use the constant yield method described in Section 1276 to calculate market discount accruals. For covered securities with original issue discount, report market discount on Form 1099-OID rather than Form 1099-INT. Market discount on tax-exempt securities is includible in taxable income as ordinary interest income.
Step 11: Complete FATCA Reporting Requirements
Check the FATCA filing requirement box if you are a U.S. payer reporting on Form 1099-INT to satisfy your Chapter 4 account reporting requirement with respect to a U.S. account as described in Regulations section 1.1471-4. Also check this box if you are a Foreign Financial Institution reporting payments to a U.S. account pursuant to an election under Regulations section 1.1471-4. When this box is checked, you must also include an account number on the form.
Step 12: Handle Nominee Reporting Situations
If you receive interest as a nominee for the actual owner, you must file Form 1099-INT showing yourself as the payer and the actual owner as the recipient. Provide Copy B to the actual owner by the recipient deadline. File Copy A with the IRS along with Form 1096. Important exception: A spouse is not required to file a nominee return to show amounts owned by the other spouse for jointly owned accounts. This exception reduces duplicate reporting for married couples.
Step 13: Furnish Statements to Recipients
Provide Copy B of Form 1099-INT to each recipient by January 31, 2022. The statement must include all information shown on the form filed with the IRS, the legend shown on Copy B of the official form, and an indication that the information is being furnished to the IRS. If you provided Forms 1099-INT to recipients at the time of transactions during the year, do not include those same amounts in another Form 1099-INT for the same recipient covering other payments.
Step 14: File Returns with the Internal Revenue Service
File Copy A of Form 1099-INT with the IRS by February 28, 2022, if filing on paper. If filing electronically, the deadline extends to March 31, 2022. Electronic filing requires software that generates files according to specifications in IRS Publication 1220. Submit paper forms with Form 1096 as a transmittal document. Do not file Copy A forms printed from the IRS website, as they are not scannable and may result in penalties.
Step 15: Maintain Proper Documentation and Records
Retain copies of all Forms 1099-INT filed, along with supporting documentation, including TIN verification records, bond premium calculations, backup withholding computations, and recipient notifications regarding elections. Keep records that substantiate all amounts reported on information returns. Maintain these records for at least three years from the due date of the return, or longer if required by other tax provisions. Proper recordkeeping protects against penalties and facilitates any IRS inquiries regarding your information return filings.
Special Reporting Rules
Covered Securities and Premium Amortization
For taxable covered securities other than U.S. Treasury obligations, report bond premium amortization in Box 11 unless the holder elected out of Section 171 premium amortization. For U.S. Treasury obligations that are covered securities, report premium amortization in Box 12. For tax-exempt covered securities, report premium amortization in Box 13. You may report either net interest amounts with premium already deducted or gross amounts with separate premium reporting. If the premium exceeds interest paid on the obligation, special loss treatment rules under Regulations section 1.171-2(a)(4) apply.
Widely Held Fixed Investment Trusts
Trustees and middlemen must report the gross amount of interest attributable to trust interest holders on Form 1099-INT if the amount exceeds $10. Determine amounts using the safe harbor rules in Regulations section 1.671-5. Furnish a comprehensive tax information statement to trust interest holders by March 15 that includes both the Form 1099-INT information and additional details required under Regulations section 1.671-5(e). Interest income information may be included in summary totals or composite statements.
REMIC, FASIT, and CDO Reporting
REMICs, FASITs, and issuers of collateralized debt obligations must file Form 1099-INT to report interest of $10 or more accrued to regular interest holders or paid to CDO holders. Single-class REMICs must increase the amount in Box 1 by the holder’s share of investment expenses and separately report these expenses in Box 5. Furnish statements to holders by March 15 containing all information required under Regulations section 1.6049-7(f). For REMIC residual interest holders, use Schedule Q of Form 1066 instead of Form 1099-INT.
Filing Penalties and Compliance
The IRS imposes penalties for failing to file correct information returns by the deadline, failing to furnish correct statements to recipients, and failing to file electronically when required. Penalty amounts vary based on how late the filing occurs and the size of your business. Intentional disregard of filing requirements results in significantly higher penalties with no maximum limit. You may avoid penalties if you can show reasonable cause for the failure. File corrected returns promptly if you discover errors after filing to minimize potential penalties.
Key Reminders for 2021 Filing
The backup withholding rate for 2021 remains 24%, unchanged from prior years. No changes to backup withholding thresholds or rates were enacted for Form 1099-INT reporting in 2021. The $10 reporting threshold for most interest payments and the $600 threshold for interest paid in the course of trade or business apply consistently. Electronic filing is mandatory if you file 250 or more information returns during the calendar year. State reporting requirements may differ from federal requirements; therefore, check the applicable state tax department guidelines for combined federal and state filing obligations.
