Overpayment

What is Overpayment? 

Overpayment in tax occurs when individual taxpayers or businesses pay more to tax authorities than what is actually owed in that particular tax period.  The excess amount is usually recoverable as a tax refund (although not in total) by the taxpayer if they file a refund claim within a specific time frame.   

 

Causes of Overpayment 

Here are some of the main causes: 

  • Misunderstanding tax withholding instructions is one of the most common causes of overpayment.    
  • Entering incorrect data 
  • Misjudging income or failing to account for deductible expenses. 
  • Not updating tax withholding after life changes like marriage, having a child, or a new job.  
  • Incorrectly filing as an employee instead of an independent contractor or vice versa. 
  • Improper use of credits and exemptions like the Earned Income Tax Credit (EITC) or the Child Tax Credit.   
  • Exceeding allowable contributions to IRAs or HSAs can lead to excess tax payments. 

 

Steps to prevent overpayment 

To avoid overpaying, there are a few proactive measures one can take. Using IRS resources, such as Publication 596 for the EITC or Form 1040-ES, can help determine eligibility and ensure accurate claims as well as aid in accurate quarterly payment calculations. Regularly reviewing withholding preferences and adjusting Form W-4, especially after major life changes like marriage or the birth of a child, is important. Maintain records of deductions, such as charitable contributions, student loan interest, and medical expenses, to claim all eligible tax benefits. 

 

Claiming Refund 

Taxpayers can claim a refund for overpaid taxes by filing the appropriate tax form. Individuals use Form 1040, 1040-SR, or 1040-X, while corporations use Form 1120, 1120X, or 990-T. 

Refunds can be received via direct deposit into a bank, credit union, or financial institution, or by paper check mailed to the taxpayer. The IRS also allows taxpayers to apply part or all of their refund toward purchasing Series I Savings Bonds. 

The total refund amount depends on various factors, including any outstanding debts owed to the government. To claim a refund, taxpayers must file their claim within three years of the original due date of the return (or within two years of tax payment, whichever is later).

Minimum Taxable Income

What is the minimum taxable income?  

Minimum taxable refers to the least amount of gross income that an individual, estate, or trust must from the tax year, in order to be mandated to file a federal income tax return with the IRS. This threshold is income-based and varies with the types of filing status, age, dependency status, and kind of income, as prescribed by IRS rules. This means it is the point above which income exceeds either standard deductions, personal exemptions when due, or any other adjustment – part of income is taxed or requires return to file for refunds. 

 

What are the Filing Thresholds?

The IRS has laid out yearly income levels for determining if a tax return is necessary. These tie into the standard deduction, which bumps up slightly each year with inflation and even more for persons over 65 or blind. Here is a snapshot for 2024 (as of March, 2025, looking back):  

  • Single: $13,850 (under 65); $15,700 (aged 65 or older).  
  • Married Filing Jointly: $27,700 (both under 65); $30,700 (both 65 or older).  
  • Head of Household: $20,800 (under 65); $22,650 (65 or older).   
  • Dependent: $1,250 from work or $400 from things like interest (whichever’s more than their standard deduction).  

These numbers assume a fairly simple income situation, without interesting twists like self-employment or strange credits.  

 

Types of Income Considered

  • Gross Income: All the wages; salaries; tips; interest; dividends; rental income; business income; and other sources, before deductions or exemptions.  
  • Earned Income: Money received from work, such as wages, or profit from self-employment.  
  • Unearned Income: Passive income, such as by interest, dividends, or capital gains.  

Exclusions (not counted toward the minimum) may include tax-exempt interest or certain social security benefits except to the extent that they create separate filers within requirements.

 

What are Special Cases?

Some situations tweak the rules: 

  • Self-Employment: Net $400 or more from a side hustle or business? A return’s needed, even if total income’s low, thanks to self-employment tax. 
  • Dependents: Kids or others claimed on someone’s return have lower triggers—$1,250 from work or $400 from investments—if it beats their deduction. 
  • Social Security Benefits: Usually tax-free but paired with other income over a limit (like $25,000 for singles), a return might be due. 
  • Refundable Credits: Income below the line? Filing can still unlock goodies like the Earned Income Tax Credit (EITC) or Additional Child Tax Credit (ACTC). 

 

How It’s Calculated

  • Start with gross income from all sources. 
  • Subtract exclusions (e.g., tax-exempt interest) to determine the income that counts toward the filing threshold. 
  • Compare this to the applicable minimum based on filing status and age. If it’s higher, a return is required unless other rules apply (e.g., self-employment). 
  • After filing, taxable income is further reduced by the standard deduction or itemized deductions and any remaining personal exemptions (pre-2018 tax law), but the “minimum taxable income” concept focuses on the filing trigger, not the final tax liability. 

 

Reporting

  • Individuals fill Form 1040 (or variants like 1040-SR for seniors) to report income and determine if tax is owed or a refund is due. 
  • Dependents may use Form 1040 if their income exceeds the threshold or to claim refunds. 
  • Self-employed individuals file Schedule C (business income) and Schedule SE (self-employment tax) with Form 1040. 

 

Exceptions and Adjustments:

  • Foreign Income: U.S. citizens or residents with foreign income must include it in gross income, potentially triggering a filing requirement even if below domestic thresholds. 
  • Married Filing Separately: The threshold drops to $5 if one spouse itemizes deductions, regardless of income level. 

 

Penalties:

  • Failing to file when income exceeds the minimum threshold can result in penalties of 5% of unpaid tax per month, up to 25%, plus interest, unless reasonable cause is shown. 
  • Not filing to claim a refund within three years forfeits the refund. 

Electronic Filing (E-Filing)

What is Electronic Filing? 

The process by which individuals, businesses, and tax professionals submit tax documents to the IRS or state revenue agency over the Internet is known as E-filing. The documents included here are income tax returns (like Form 1040 for individuals or Form 1120 for corporations), information returns (like Form 1099), employment tax returns (like Form 941), and extension requests (like Form 4868). This process has effectively replaced the physical paper forms, mailing, and manual processing with an efficient digital workflow.

 

Options for e-filing:

  • Tax Preparation Software: Individuals and businesses prepare and e-file their returns with Modernized e-File (MeF) system (like Tax1099).
  • Tax Professionals: Authorized e-file providers or Electronic Return Originators (EROs) can prepare and transmit returns on behalf of taxpayers.  
  • Direct Filing Systems: IRS Direct File permits eligible taxpayers to file directly with the IRS without the need for third-party software.  

After electronically transmittal of the returns to the IRS, an acknowledgement receipt is generated (instantly or within hours), processing the returns successfully. 

 

History of E-Filing   

E-filing traces its origins back to the early 1980s when an electronic filing program was launched on a pilot basis by the IRS. It was intended to slow down the rate of paper usage and operational costs. Originally, it was opened to a limited audience of tax preparers in selected cities. Here’s other significant milestones determining the extended growth of this program:  

  • 1987: Introduction of direct deposit for the purpose of refund payments being electronically deposited.  
  • 1990: In this year, the IRS processed 4.2 million e-filed returns, thus marking a growing acceptance of this service.  
  • 2003: The IRS moved to the Modernized e-File (MeF) system, a web-based application producing applications of Extensible Markup Language (XML) for more flexibility and efficiency.   
  • 2020: IRS allows taxpayers to directly e-file via Free File Fillable Forms, thus, for some taxpayers, there was no need to involve third-party intermediaries.   
  • 2024: The concept of Direct File pilot was introduced by the IRS to be free and IRS managed for taxpayer electronic filings, based on the 2022 Inflation Reduction Act provisions. 

By 2018, 89% of U.S. tax returns were filed electronically, reflecting a shift from paper-based filing to a near-universal digital standard. Today, e-filing is the preferred method for most taxpayers due to its speed and reliability. 

 

How Electronic Filing Works 

The e-filing process involves several steps, depending on the method chosen: 

  1. Preparation: Taxpayers gather necessary documents (e.g., W-2s, 1099s) and input data into tax software or provide it to a tax professional.
  2. Validation: The software checks for errors, such as incorrect Social Security numbers or missing forms, ensuring compliance with IRS requirements.
  3. Transmission: The return is converted into a digital format (often XML) and transmitted securely to the IRS via the internet. For MeF, this involves authorized providers or direct submission to IRS servers.
  4. Acknowledgment: The IRS processes the return and sends an electronic acknowledgment (typically within 24-48 hours) confirming acceptance or identifying rejection reasons (e.g., duplicate filings or data mismatches).

Taxpayers can pay dues/ balances electronically (e.g., via bank withdrawal or credit card) or receive refunds through direct deposit. 

For businesses, additional systems like the Information Returns Intake System (IRIS) or Filing Information Returns Electronically (FIRE) facilitate e-filing of forms.

Note: From TY 2023, the IRS mandates e-filing of 10 or more than 10 information tax returns (1099s).

 

Benefits of Electronic Filing

E-filing offers numerous advantages over traditional paper filing: 

Speed

Returns are processed faster, and receipts are received in hours instead of weeks. Refunds get transferred directly into a bank account within a span of ten days, instead of 6-8 weeks for paper returns.  

 

Precise & Accurate

Electronic filing is more accurate than paper filing due to several key factors. It is less prone to human errors, such as incorrect data entry or misinterpretation of tax codes. Some of the software contains built-in error-checks that tend to reduce mistakes such as missing or incorrect data.  

 

Convenience:

There could be an urgent need of filing taxes or tax forms at any hour, on any day. Therefore, they require the flexibility to file from anywhere in the world connected to the Internet. This eliminates the need to visit post office, and make sure deadlines are met without the risk of mail delivery delays.

 

Security

Data is encrypted for transmission, making it much easier to store sensitive information, and electronic records are much easier to access than paper files.

 

Reduced Costs:

The IRS saves costs in the process as savings in administrative costs because taxpayers can save costs from using free filing options or reduced late penalty by early submission.  

 

Ecological Impact:

It reduces waste in paper, complements the objectives of environmental sustainability.  

Electronic filing allows businesses to comply with the electronic submission requirements set by the partnerships with over 100 partners or requiring the filers of 10 or more information returns. 

 

Requirements and Eligibility

Access to e-filing is almost everywhere but still has some specific requirements and eligibility conditions such as: 

  • Software: For taxpayers to e-file, the use of IRS-certified software or an e-file provider is necessary. For businesses, a Transmitter Control Code (TCC) may also be needed for systems like IRIS or FIRE. 
  • Identity Verification: Individual social security number (SSN) or Individual Taxpayer Identification Number (ITIN), while in businesses, needs an Employer Identification Number (EIN).  
  • Filing Thresholds: All businesses filing 10 information returns required to e-file, as of 2023, according to Treasury regulations, are those who file 10 or more information returns such as Forms W-2 and 1099. Big corporations, for instance, those with assets over $10 million, are also mandated to e-file their major returns. 

  • Supported Forms: Most conventional forms such as 1040, 941, and 1099 can be e-filed; however, some niche forms such as certain trusts or international filings still need paper submission. 

 

Practical Applications and Options

E-filing caters to diverse taxpayer needs: 

  • Individuals: Use IRS Free File, Direct File, or commercial software for Form 1040 and related schedules. Extensions can be requested via Form 4868 electronically. 
  • Businesses: File employment taxes (Forms 940-945), corporate returns (Form 1120), or partnership returns (Form 1065) through MeF or third-party providers. IRIS supports free 1099 filing. 
  • Tax Professionals: EROs use specialized software to file multiple clients returns, adhering to e-file mandates for preparers handling 11 or more returns annually. 

Special Cases- Exempt organizations (Form 990), excise tax filers, and international taxpayers have tailored e-file options, though some exceptions apply. 

 

Future of E-Filing

The IRS continues to enhance e-filing through initiatives like Direct File, which aims to expand eligibility and integrate state tax filing. Advances in artificial intelligence and cloud technology may further simplify preparation and submission. While stricter e-file mandates for businesses reflect a push toward full digitization. As of March 28, 2025, e-filing remains a dynamic tool, evolving to meet taxpayer needs and government efficiency goals.

TIN Matching

What is TIN Matching? 

TIN Matching is a process that ensures that a payee’s TIN and name align with the IRS database. This process is designed to ensure that correct information is reported before submitting tax filings.

The IRS maintains a database specifically for TIN Matching. When a business or authorized user submits a TIN and corresponding name, the system checks for a match.  

 

Why is it Necessary?  

Mistakes in tax reporting can lead to compliance issues. If a business submits an incorrect TIN/name combination, it may receive an IRS B-notice, requiring additional verification. If the error isn’t fixed, the business may have to apply backup withholding, deducting taxes from payments made to the payee.  

TIN Matching helps businesses avoid these issues by confirming tax details ahead of time. It also ensures compliance with IRS regulations, streamlines vendor onboarding, and reduces the risk of dealing with fraudulent information. Simply put, it’s a safeguard against tax reporting mistakes that could cost businesses time and money. 

 

Benefits of TIN Matching

It offers several benefits, including: 

  • Preventing IRS B-notices and penalties  
  • Speeding up vendor onboarding   
  • Ensuring tax compliance 
  •  Detecting identity errors before they become problems. 
  • Improving business efficiency  
  • Minimize manual verification efforts

 

How Does TIN Matching Work? 

The TIN Matching process starts with a business’s collecting TINs from vendors, independent contractors, or other payees using Form W-9. These TINs can be: 

  • Employer Identification Numbers (EINs) for businesses 
  • Individual Taxpayer Identification Numbers (ITINs) for certain individuals 
  • Social Security Numbers (SSNs) for sole proprietors or individuals 

Once collected, the business submits the TINs for verification through the IRS Taxpayer Identification Numbers Matching system. The system then checks if the name/TIN combination matches the IRS database. If there are discrepancies, the business needs to correct the information before filing.

Preparer Tax Identification Number (PTIN)

What is Preparer Tax Identification Number? 

IRS Preparer Tax Identification Number (PTIN) is a unique 8-digit identification number given to tax professionals or tax preparers who prepare IRS forms on behalf of their clients. Any individual who is compensated for preparing, calculating and filing income tax returns on behalf of individuals and business are required to have a valid PTIN. Most IRS forms require a PTIN when filing.   

 

Why is an IRS PTIN Important?   

The IRS first introduced PTIN in 1999 to protect the privacy of tax preparers. Since then, this initiative has led to a more secure method of identification and reduced reliance on Social Security numbers.   

The primary purpose of PTINs is to provide a way for the IRS to track and regulate tax return preparers. By requiring tax professionals to use PTINs, it enhances the accuracy and compliance of the tax return process. They also allow the IRS to identify and communicate with tax professionals regarding their responsibilities. 

For tax professionals, having a PTIN is a regulatory requirement and adds to their professional credibility. 

 

Applying For a PTIN 

In order to apply for a PTIN, the tax preparer must have the following information:    

  • Social Security number  
  • Personal information (name, mailing address, date of birth)  
  • Business information (name, mailing address, telephone number)  
  • Previous year’s individual tax return (name, address, filing status)  
  • Explanations for felony convictions (if any)  
  • Explanations for problems with U.S. individual or business tax obligations (if any)   
  • Credit/Debit/ATM card   
  • Any U.S.-based professional certification information (If applicable). 

 

Once all the information is gathered, follow these easy steps to obtain a PTIN: 

Step 1 – Create an account by providing a name and email address. 

Step 2– Complete the online application by providing personal information, previous year’s tax return, credentials, and more. 

Step 3– Pay the $19.75 fee by credit/debit/ATM card or eCheck. 

Step 4– After completion of the online application, the PTIN will be provided. 

 

 

Renewing a PTIN 

PTIN applicants must renew their PTIN every calendar year for it to be valid. Failure to renew and have a current PTIN could result in penalties, injunction, and/or disciplinary action by the IRS Office of Professional Responsibility.   

Renew your PTIN in 3 easy steps: 

Step 1– Log in to existing PTIN account 

Step 2– Complete the online renewal application by verifying personal information and answering a few questions. 

Step 3– Pay the $19.75 renewal fee and upon completion, the PTIN will be renewed. 

 

Reporting Period (Tax Year)

What is a Reporting Period? 

A reporting period is a defined period or specific time frame used for financial reporting. It breaks down financial activities into designated time periods to help stakeholders assess financial progress and make informed decisions. It is especially essential for accounting, tax filing, and financial reporting.   

Without a defined reporting period, financial statements may lack accuracy and consistency, making it harder to assess a company’s financial health. A specific reporting period will provide a clear timeframe and make financial reporting easier.

When it comes to tax filing, the reporting period (Tax Year) refers to the 12-month period (either calendar or fiscal year) that covers a tax return. A tax year typically lasts 12 months or 52 to 53 weeks and is the period of activity that is considered when calculating tax and filing tax returns. It is required under the Internal Revenue Code and the Income Tax Regulations.   

Most taxpayers in the U.S. use a calendar year, i.e., the 12 months from January 1 through December 31. Some also use the fiscal year, which is a 12-month period that ends on the last day of any month except December.   

 

Types of Reporting Periods (Tax Year)  

Calendar Tax Year  

The calendar tax year is the most common reporting period. It follows the annual calendar and runs from January 1 to December 31.  This year-long period is simple since it aligns with the conventional calendar. It is commonly used by individual taxpayers.

Example: If you earned income from January 1, 2024, to December 31, 2024, you would report this income on your 2024 tax return, which is due by April 15, 2025.

 

Fiscal tax year  

A fiscal tax year refers to any 12-month period that ends on a day other than December 31. Businesses, mostly seasonal businesses, often use a fiscal year to better match their income and expenses.   

Example: A retail business that experiences peak sales during the holiday season might choose a fiscal year ending on January 31. This way, the entire holiday season’s revenue and expenses are included in one tax year that simplifies financial analysis and planning.

 

Short Tax Year 

A short tax year is a tax year that is less than 12 months. It is used when a new business starts in between a tax year.  It can also occur when a business decides to change its taxable year or accounting period, which requires the IRS’s approval using Form 1128. 

Example: If a company starts on August 1 and uses a calendar year, its first tax year will be from August 1 to December 31, resulting in a short tax year of five months.

 

State Tax Year 

Every single one of the states handle taxation independently of the federal system. With most of the states following the same system as the federal government where taxpayers need to file tax returns based on the calendar year and use April 15 as their required filing date.

Exceptions: While most states follow this system, there can be exceptions with different filing deadlines or fiscal years. It’s always important to check the specific requirements for your state to ensure compliance.
