Form 945 is the annual return the Internal Revenue Service requires from businesses that withhold federal income tax from non-payroll payments. Unlike employment-related filings, this form applies to specific distributions such as annuities, government payments, and other benefits not covered by payroll. Many taxpayers feel uncertain about these obligations, and understanding federal tax liability begins with identifying when an annual return must be filed. By clarifying these rules, you can determine whether your company is subject to filing.

Filing requirements vary depending on the type of money withheld and the persons or parties responsible for it. For example, an employer identification number is necessary when reporting withheld federal income tax from tax-favored retirement plans, gambling winnings, or certain government payments. Each employer must review figures carefully to avoid notices and fees. The reported totals must align with maintained records, and when the date falls on a weekend or holiday, the next business day rule applies. This ensures the return is processed correctly and without delays.

This guide aims to provide precise knowledge and support for individuals, businesses, and other eligible taxpayers who must manage these requirements. We will cover key filing rules, show how to create accurate reports, and explain options if notices are received. While the rules may seem complex, this structured walkthrough simplifies the process into steps you can follow and review. By the end, readers will have the information to complete Form 945 accurately.

Who Must File and Withhold Federal Income Tax

Businesses and individuals making non-payroll payments must determine if Form 945 is required. The Internal Revenue Service directs taxpayers to report federal income tax withheld from annuities, government payments, and other types of distributions. Filing obligations arise when federal tax liability is created, and the annual return records these amounts to keep taxpayers compliant.

The form applies when tax is withheld from retirement plans, gambling winnings, or voluntary government payments. An employer identification number is required, and reported figures must match deposit records. Responsibility falls on those managing withholding, such as company officers or financial managers. Failure to meet these obligations can result in added costs for businesses and workers.

Examples of Non-Payroll Payments

Examples of non-payroll payments that require reporting include the following:

  • Pension and retirement plan distributions: Withheld federal income tax applies to eligible tax-favored retirement plans and annuities.

  • Gambling winnings: Money withheld from casinos, lotteries, or similar activities must be reported as part of the total amount.

  • Military retirement payments: Workers and estates receiving benefits are included in federal reporting requirements.

  • Indian gaming profits: Distributions subject to withholding must be listed with other items on the annual return.

  • Voluntary withholding on government payments: Taxpayers may choose to have amounts withheld from specific government sources.

Backup Withholding and Responsibilities

Businesses must account for backup withholding when taxpayers provide incorrect identification numbers. These amounts are reported with regular withholding, and the Internal Revenue Service reconciles them on the annual return. Filing is required once federal tax liability exists, even for small amounts, and thorough reporting ensures employers and employees meet their responsibilities.

Determining who must file starts with reviewing payment categories in federal guidance. Employers must check the type of distribution, confirm withholding, and ensure deposits match reported amounts. Each return must be supported with accurate records, allowing taxpayers to manage filing confidently while avoiding unnecessary fees.

Filing Requirements, Employer Identification Number, and Key Deadlines

Meeting filing requirements for Form 945 begins with understanding who must submit the annual return. Businesses and individuals withholding federal income tax from non-payroll payments must file with the Internal Revenue Service. Filing is mandatory once federal tax liability exists, and accuracy depends on providing correct identification and deposit records. Establishing compliance at this stage prevents notices and added fees.

Employer Identification Number and Filing Obligations

An employer identification number is required to complete Form 945. The Internal Revenue Service uses it to match deposits, notices, and annual returns to the correct account. Missing or incorrect numbers delay processing and may lead to higher costs. Keeping records accurate ensures the number remains properly linked to the business entity.

Filing obligations extend to companies making distributions from tax-favored retirement plans, entities paying government benefits, and organizations handling other items such as annuities or gambling winnings. Each filer must determine eligibility based on money withheld and confirm that deposits match the total amount due. Failing to meet these obligations places businesses and responsible persons at risk of IRS enforcement actions.

Key Filing Deadlines

Form 945 is due annually, with the filing date falling in January for the prior tax year. If the deadline falls on a weekend or legal holiday, the Internal Revenue Service accepts the return on the next business day. Deadlines change based on whether the return is mailed or filed electronically, making early preparation necessary for accuracy. Businesses should review requirements before January to avoid last-minute issues.

The Internal Revenue Service provides guidance on deadlines, employer identification number rules, and filing eligibility for Form 945, available here: About Form 945, Annual Return of Withheld Federal Income Tax. Meeting requirements with accurate records and timely preparation helps taxpayers file correctly, report federal tax liability, and avoid unnecessary costs.

Gathering Information Before Filing

Preparing Form 945 begins with collecting the records and identifiers needed to accurately report withheld federal income tax. Every taxpayer must ensure the information matches deposits and other items already submitted to the Internal Revenue Service. Maintaining these documents supports compliance, reduces the risk of errors, and helps responsible persons manage reporting obligations effectively.

Essential Identification and Forms

  • Employer identification number: This number is required to link deposits and notices to the correct taxpayer account.

  • Forms 1099 and W-2G: These forms confirm distributions, annuities, and gambling winnings subject to withholding.
  • Prior year Form 945: This form is helpful for comparison to ensure figures remain consistent across annual returns.

Records of Deposits and Transactions

  • Federal tax deposit confirmations: These provide proof of amounts already transferred to the Internal Revenue Service.

  • Bank account details: These are required to manage electronic transfers and reconcile totals.

  • Backup withholding records: These are needed if incorrect taxpayer identification numbers triggered additional withholding.

Notices and Supporting Documentation

  • IRS notices or correspondence: These reference previously identified issues or adjustments.

  • Internal worksheets: Business officers reviewed them to confirm that the total amount withheld matches the reported figures.

  • Third-party reports: These are generated by payroll processors or financial institutions that handle government payments and other distributions.

Maintaining these documents creates a complete picture of annual tax liability. Employers and other responsible parties can use the information to verify eligibility, determine the correct filing category, and confirm that deposits equal reported amounts. 

Preparing early ensures that deadlines are met and filings remain accurate. Comprehensive records protect businesses and workers, allowing taxpayers to confidently manage obligations and avoid unnecessary fees.

Step-by-Step Instructions for IRS Form 945

Completing Form 945 requires accuracy at every stage to ensure federal tax liability is reported correctly. Businesses and individuals responsible for withholding must confirm that all non-payroll payments are included, deposits are accurate, and totals align with Internal Revenue Service expectations. Following a structured process helps filers avoid errors, manage their records, and demonstrate compliance if the return is later reviewed.

Step 1: Gather Identification and Records

Start with a checklist of essential documents. Collect the employer identification number, Forms 1099, and W-2G related to distributions, annuities, or gambling winnings. Include deposit confirmations and any notices received from the Internal Revenue Service. Having these materials ready creates a foundation for completing the annual return accurately.

Step 2: Complete the Header Section

Enter the business name exactly as it appears on IRS records and the correct employer identification number. Add the business address, including state and ZIP code. If the filing represents a final return because the business has closed, mark the “Final Return” box and attach the required supporting information.

Step 3: Report Withheld Federal Income Tax

Line 1 requires the total amount of federal income tax withheld from distributions, government payments, and other types of non-payroll income. This figure includes tax-favored retirement plans, military retirement benefits, and other items subject to withholding. Ensure the numbers reconcile with deposit records to prevent discrepancies.

Step 4: Enter Backup Withholding

Line 2 is for backup withholding, which applies when taxpayers fail to provide accurate identification numbers. These amounts must be combined with regular withholding to reflect the full liability. Transparent reporting ensures the Internal Revenue Service can reconcile deposits with reported figures.

Step 5: Calculate Total Taxes and Deposits

Add lines 1 and 2 to determine the total tax liability for the year. Report all deposits made during the prior year, including carryovers or corrections from earlier filings. The total amount must match federal tax deposit records to avoid issues with processing.

Step 6: Balance Due or Overpayment

If the total liability exceeds deposits, enter the difference as the balance due. Smaller liabilities under specific thresholds may allow payment at the time of filing. If deposits exceed liability, record the overpayment and indicate whether it should be refunded or applied to the following year’s return.

Step 7: Monthly Tax Liability Summary

Complete this section if you are a monthly depositor and the total tax liability is $2,500 or more. List the amount for each month, ensuring the totals equal the figure entered on line 3. If liability reached $100,000 or more in any month, complete Form 945-A instead of this summary.

Step 8: Third-Party Designee and Signature

Authorize a designee if you want another person to discuss the return with the Internal Revenue Service. Depending on whether the filer is an individual, a partnership, or a corporation, the appropriate officer or responsible person must sign on. A valid signature finalizes the form and confirms responsibility for reported amounts.

Step 9: File Electronically or by Mail

Electronic filing through the IRS Modernized e-File system or authorized providers is preferred, as it provides immediate confirmation. If mailing, send the form to the correct processing center based on location and whether a payment is enclosed. Confirm deadlines to ensure the return is received on time.

The Internal Revenue Service provides official instructions for each return line, including filing guidance and examples. You can access the agency’s resource here: IRS Form 945 Instructions. Following each step carefully ensures the form is accurate, deposits are correctly matched, and taxpayers meet their obligations. A structured approach creates confidence in compliance, allowing filers to manage responsibilities without unnecessary stress.

Payment, Deposits, and Backup Withholding

Managing deposits for Form 945 ensures that withheld federal income tax is applied correctly to federal tax liability. Every filer must understand how schedules vary depending on total amounts withheld, the type of non-payroll payments involved, and whether deposits qualify under monthly or semiweekly rules. Careful planning allows taxpayers to align deposits with Internal Revenue Service requirements while limiting added costs.

Deposits are generally made through the Electronic Federal Tax Payment System, which provides confirmation numbers for recordkeeping. Businesses must track the total amount of deposits throughout the year and verify that these match the figures reported on the annual return. Timing matters, since the due date for deposits changes when liability reaches specific thresholds or when the date falls on a weekend or legal holiday.

Key Deposit Rules and Considerations

  • Electronic deposits required: All deposits must be processed electronically, except for minimal exceptions.

  • Monthly vs. semiweekly schedules: Liability under $50,000 typically uses monthly deposits, while larger figures trigger semiweekly schedules.

  • Following the business day rule: Any liability of $100,000 or more requires a deposit on the following business day.

  • Carryover adjustments: Overpayments from earlier filings can be applied to current deposits and balance accounts.

  • Backup withholding reporting: Taxpayers must include amounts withheld when identification numbers are missing or incorrect.

  • Recordkeeping of confirmations: Documentation must support each deposit to protect against disputes or errors.

The Internal Revenue Service checks deposits to confirm that withheld funds from distributions, annuities, gambling winnings, and other items were submitted correctly. Responsible persons must ensure deposits match the annual return to avoid scrutiny. Organized records and awareness of backup withholding strengthen compliance and help businesses protect employees while meeting federal tax obligations.

Penalties, Interest, and Relief Options

Failing to file Form 945 or missing required deposits creates additional costs for taxpayers. The Internal Revenue Service applies structured charges when businesses do not meet their federal tax liability on time—understanding how these charges work and the relief available allows employers and responsible persons to manage obligations more effectively.

Common Charges Applied

  • A failure-to-file charge is added when the annual return is not submitted by the required deadline, based on the unpaid amount.

  • A failure-to-pay charge is imposed when taxpayers do not cover their total due amount, even if the return is filed correctly.

  • Late deposit charge: This charge is applied when deposits are not made on schedule; the rate varies depending on the lateness of the deposit.

  • Daily interest: Accrues on unpaid balances until the figure is settled, compounding the total cost for taxpayers.

Relief Options Available

  • Reasonable cause abatement: Granted when documented circumstances, such as serious illness or natural disasters, prevent timely filing or payment.

  • First Time Abate: Available to eligible taxpayers who have a clean compliance history and meet filing requirements in other years.

  • Administrative relief:  Provided in limited cases where Internal Revenue Service guidance recognizes qualifying circumstances.

The Internal Revenue Service describes how reasonable cause relief works for taxpayers who meet eligibility criteria. Details are available here: IRS Penalty Relief for Reasonable Cause. Understanding how charges are applied and which relief measures exist helps businesses prepare, respond to notices, and limit additional costs. A clear understanding of these options supports responsible tax management and encourages proactive compliance.

Trust Fund Recovery Penalty and Personal Liability

When businesses fail to remit withheld federal income tax from non-payroll payments, the Internal Revenue Service may impose a Trust Fund Recovery Penalty. This penalty is one of the agency's most serious actions, as it assigns personal liability to individuals who control the funds. Understanding how it works helps taxpayers identify risks, safeguard compliance, and prepare responses if contacted by the agency.

Key Features of the Trust Fund Recovery Penalty

  • Definition: The Trust Fund Recovery Penalty applies when withheld federal income tax is not deposited. These funds are considered government property once taken from distributions, annuities, gambling winnings, or non-payroll payments.

  • Who is responsible: Liability extends to persons with authority over the money, such as company officers, partners, or managers who manage deposits and returns. Third parties, like bookkeepers with signature authority, may also be held responsible.

  • Amount imposed: The penalty is equal to the total amount of tax not deposited. Interest accrues until the figure is resolved, increasing the burden for those found liable.

  • Impact on estates and individuals: The liability follows the responsible person, not the business. Estates of deceased individuals can also be charged, and bankruptcy does not discharge the obligation.

  • Investigation process: The Internal Revenue Service interviews and reviews records to determine who knew and controlled funds. Persons identified may receive notices requesting documentation and testimony.

  • Defenses available: Demonstrating a lack of authority, absence of willfulness, or evidence that another party controlled deposits can reduce or eliminate liability: detailed records and timely responses to notices provide essential support in these cases.

Assigning personal liability ensures that federal income tax from employees, retirees, or other taxpayers is withheld and remitted to the federal government. Understanding this penalty's reach reinforces the importance of timely deposits and accurate reporting for businesses. Responsible persons who ignore these duties expose themselves to financial harm beyond the business entity.

Businesses and individuals can proactively manage their obligations by recognizing how the Trust Fund Recovery Penalty works and who may be targeted. Maintaining clear records, ensuring deposits match annual returns, and designating responsible officers properly help reduce risk. Awareness of these rules also strengthens internal controls and promotes accountability across financial operations.

Recordkeeping, Compliance, and Other Items

Accurate recordkeeping is critical for meeting federal tax obligations under Form 945. The Internal Revenue Service expects employers and responsible persons to maintain documents that confirm deposits, identify taxpayers, and reconcile totals reported on the annual return. Organized files support compliance and provide essential evidence during audits or inquiries. Without reliable records, businesses may struggle to prove that withholding and deposits were managed correctly.

Required Records and Retention Period

Employers must keep copies of filed forms, deposit confirmations, and notices for at least four years. Records should include taxpayer identification details, amounts withheld from distributions or annuities, and adjustments applied through prior filings. Maintaining these records allows taxpayers to verify that reported figures match deposits and helps safeguard against disputes. Storing documentation securely also ensures that estates or successor parties have access if responsibility shifts.

Compliance Practices for Businesses

Compliance requires more than filing on time; it also involves reviewing data throughout the year. Employers should reconcile deposits monthly, confirm that withholding from non-payroll payments is recorded accurately, and ensure the employer identification number is tied to the correct entity. Regular internal audits, even on a small scale, help detect discrepancies early. Businesses that manage government payments, retirement plans, or other items benefit from assigning a responsible officer to oversee withholding.

Importance of Supporting Documentation

Supporting records include bank statements, third-party processor reports, and communications from the Internal Revenue Service. These documents provide context for each deposit and strengthen the credibility of the filer’s account. Keeping reviewed documentation available when questions arise demonstrates diligence and proactive management. Clear organization also reduces stress during examinations, making it easier to respond promptly and accurately.

Reliable recordkeeping and ongoing compliance practices reduce the risk of unnecessary costs and help taxpayers manage obligations with confidence. Maintaining complete records satisfies legal requirements and supports better financial management. Businesses implementing structured recordkeeping systems are better prepared for audits and can focus on their operations, knowing that federal responsibilities are appropriately addressed.

Frequently Asked Questions

Do taxpayers need to file if no nonpayroll payments occurred?

Form 945 is required only if federal income tax was withheld from nonpayroll payments such as annuities, gambling winnings, or governmental section distributions. If no such withholding occurred, filing is not required. If amounts were withheld and not reported, the annual return must be submitted. Filing on time ensures accurate records and prevents complications for businesses and individuals responsible for managing federal tax obligations.

What’s the difference between Form 945 and Form 941?

Form 945 reports federal income tax withheld from nonpayroll payments, including government payments and retirement plan distributions. Form 941 covers employment-related withholding, such as wages and Social Security contributions. The distinction lies in the type of payment reported and the filing schedule. Form 941 is filed quarterly, while Form 945 is filed once each year, making careful separation of reporting obligations essential for compliance with Internal Revenue Service requirements.

Can you mail or e-file Form 945?

Taxpayers may file Form 945 electronically through the IRS Modernized e-File system or mail it to the correct processing center. E-filing offers faster confirmation and easier recordkeeping. Mailing remains available for those preferring paper submissions, though deadlines must be carefully observed. The annual return must accurately report withheld amounts from nonpayroll payments and include the correct employer identification number, whether filed electronically or by mail.

What happens if the form is filed late?

If Form 945 is filed late, the Internal Revenue Service may assess additional charges depending on how long the return is overdue and whether any balance remains unpaid. Filing late also increases the risk of accruing interest on amounts owed. Employers and responsible persons should file promptly, even without full payment, since timely filing reduces the severity of costs compared to filing and paying late together.

How long must records be kept for review?

Records supporting Form 945, including deposit confirmations and employer identification number documentation, must be retained for at least four years. These include details on nonpayroll payments, gambling winnings, and governmental section distributions. Organized files help demonstrate compliance if questions arise. Keeping thorough records provides evidence for employers and living estates, protecting them from disputes while ensuring withheld funds are correctly reported to the Internal Revenue Service.

Who can the Internal Revenue Service hold responsible if amounts remain unpaid?

The Internal Revenue Service may hold responsible persons accountable when businesses fail to remit withheld federal income tax. These individuals may include officers, partners, or bookkeepers with authority over financial decisions. Liability equals the total amount owed and can extend to estates. Clear documentation and accurate reporting are necessary to avoid such responsibility. Each party involved must note its duties and act responsibly to ensure compliance.

What relief options exist if you receive an IRS notice?

Taxpayers who receive a notice may request relief if they provide an explanation showing reasonable cause for late filing or payment. Options include First Time Abate relief or demonstrating hardship when full payment cannot be made. Some services are free, such as accessing forms online or contacting the Taxpayer Advocate Service. Local  IRS offices may also help taxpayers understand obligations and available relief programs in Minnesota and other states.
