According to the IRS, about $1 billion in refunds remains unclaimed due to non-filing every year. This costly misstep gains even more significance when considering that unclaimed refunds for the year 2015 alone reached an astounding $1.4 billion. This underscores the vital need to explore tax filing errors and adopt preventive measures to prevent these financial pitfalls.

As the annual tax season makes its return, we find ourselves facing a familiar challenge: the art of tax filing. It’s like a yearly puzzle where we accidentally step on some tricky spots. No worries, though – we’ve got your back.

In this blog, we’re going to unravel these common tax-time traps and give you easy ways to avoid them. Whether you’re a seasoned pro or new to the tax scene, getting the hang of these ten tax filing mistakes and learning how to steer clear of them will make the whole tax experience smoother and more confident.

Q: What is the most common mistake when filing taxes?

The most prevalent mistake while filing taxes is often related to mathematical errors in calculations and entering numbers incorrectly. Such errors can lead to discrepancies in reported income, deductions, and credits, potentially triggering audits or delays in processing.

Q: How do I avoid mistakes on my tax return?

To prevent errors on your tax return, follow these steps:

Organize Documents: Gather all necessary documents like W-2s, 1099s, and receipts.
Use Reliable Software: Utilize trustworthy tax software to minimize calculation errors.
Double-Check Information: Review personal details, income, and deductions for accuracy.
Seek Professional Help: Consult tax experts for complex situations.
E-File for Accuracy: Electronic filing reduces the chances of manual errors.
Review Before Submission: Carefully review your entire return before submitting it to the IRS.
Keep Copies: Maintain copies of your filed return and supporting documents for your records.
By taking these precautions, you can significantly lower the risk of errors on your tax return.

Mistake 1: Miscalculations in Math

As per the IRS, mathematical errors rank as one of the most frequent errors encountered during tax filing.Often, these errors stem from arithmetic blunders or transcription mistakes when transferring figures from one schedule or form to another. The consequences of such mistakes are significant and can lead to immediate correction notices from the IRS. They tend to scrutinize the math aspect of returns, and any errors can result in either a reduction in your expected tax refund or an increase in the tax bill you owe. Ultimately, these mistakes can leave you with less money in your bank account than anticipated.

To avoid falling into this mathematical trap, consider using tax software that has the capability to automatically handle calculations for you. However, it’s crucial to ensure that the initial numbers you input are accurate. If you’re not comfortable with handling these calculations yourself, enlisting the services of a tax professional is a wise choice. Additionally, retaining copies of your filed returns for at least seven years is a practice that can prove invaluable if any discrepancies arise.

Mistake 2: Errors in Deductions or Credits

When it comes to deductions and credits, making errors is a common pitfall that taxpayers can easily stumble into. These errors can encompass a variety of issues, such as failing to itemize when it’s necessary or making mistakes in crucial entries such as those related to taxable income, withholding, and estimated tax payments. It’s equally possible to mistakenly claim deductions or credits that you’re not eligible for, adding another layer of complexity to the situation.

The repercussions of these errors are substantial, often resulting in corrective notices being issued by the IRS. In turn, this can lead to diminished refunds, increased tax obligations, and potentially even penalties and interest charges if these errors aren’t addressed promptly. To shield yourself from these negative outcomes, it’s prudent to use tax software that offers prompts for deductions and credits while also verifying your eligibility. Staying current with the latest tax tables and forms is another strategy to minimize the likelihood of such mistakes.

Mistake 3: Name Errors

A seemingly simple oversight that can cause significant complications is mismatching names with the Social Security identification numbers on record with the government. While this issue tends to surface more frequently with newlyweds, it can affect anyone who has undergone a name change and failed to notify the Social Security Administration.

The repercussions of such an error can lead to delays in the processing of your return. To avert this scenario, ensure that the name you use on your return matches precisely with the name on your Social Security card. Additionally, if you’ve experienced a name change, it’s imperative to update your information with the Social Security Administration promptly.

And so forth, the article continues to detail the remaining tax filing mistakes and their corresponding strategies to avoid them. The focus remains on providing readers with comprehensive insights into these pitfalls and empowering them with the knowledge needed to navigate the tax filing process successfully.

Mistake 4: Incorrect Account and Routing Numbers

Another area where errors can creep in is in entering account and routing numbers, particularly when dealing with multiple accounts. The consequences of these errors can be far-reaching, potentially leading to the loss of refunds as they’re directed to the wrong account or even being returned to the IRS.

To prevent such mishaps, it’s imperative to exercise extreme caution and double-check the accuracy of the numbers you’re inputting. This rule applies even if you’re dealing with a single account. Additionally, if any account details are auto-populated by the software you’re using, make sure to verify that these details are still accurate.

Mistake 5: Failing to Report Additional Income

For individuals with non-W-2 earnings, neglecting to report this additional income is a common oversight. This can include earnings for paid work performed or income from bank and investment accounts, among others. It’s essential to keep in mind that the IRS is automatically informed about this additional income and cross-references it with the information on your return.

The impact of failing to report such earnings can be substantial. It might artificially inflate your refund or lead to your return showing a lower tax obligation than what is accurate. To avoid these pitfalls, it’s crucial to maintain accurate records of any non-W-2 earnings that don’t have taxes withheld. Also, ensure that you retain all Forms 1099 received as they’re essential for accurate tax preparation.

6: Filing Under the Wrong Status

Selecting the incorrect filing status is a common mistake that can have significant implications for your tax situation. There are various options, including single, married filing jointly, married filing separately, head of household, and qualifying widow(er) with a dependent child. However, only one of these options can be chosen.

Filing under the wrong status can lead to reduced refunds or higher tax payments. To steer clear of this error, make sure you have a clear understanding of each filing status. Using tax software can be incredibly helpful as it often guides you through the process and only allows you to select an appropriate status. Some software might even show you the different statuses you’re eligible for, along with the potential impact on your refund or payment for each.

7: Incorrect or Missing Social Security Number

Failing to provide the correct Social Security numbers or omitting them altogether is an error that can cause headaches during the tax filing process. These numbers are crucial for various transactions, including income statements, deductions, and credits.

The consequences of such errors can lead to processing delays for your return. To avoid these setbacks, always double-check that you’ve included all the necessary information before submitting your return. It’s especially crucial to meticulously review Social Security numbers, particularly when dealing with spouses and dependent children.

8: Improper Deduction of Charitable Contributions

Charitable donations are a valuable way to contribute to causes you care about and potentially receive tax deductions. However, improperly handling these deductions can result in errors that impact your tax return. This includes not accurately calculating your donations or claiming deductions for non-cash contributions that aren’t in good or better condition.

The consequences of these errors can lead to reduced refunds or increased tax obligations. To navigate this terrain, take care to meticulously calculate all your charitable donations when filing. Additionally, adhere to all the rules related to donation deductions, ensuring that you’re donating to qualified, tax-exempt organizations.

The blog continues in this vein, delving into the remaining two mistakes and their corresponding avoidance strategies. By providing readers with a comprehensive understanding of these common tax filing errors and the steps they can take to sidestep them, the article aims to empower individuals to approach tax filing with confidence and accuracy.

9: Missing Required Signature

Overlooking the requirement to sign your tax return or forgetting to have both spouses sign, especially when filing jointly, is a mistake that can render your return invalid. This oversight can have serious consequences, as an unsigned return is essentially as if it was never filed at all. Such situations can potentially lead to penalties for failing to file or pay taxes.

To avoid this predicament, it’s advisable to make sure that any required signatures are in place before submitting your return. Some tax return software applications might auto-fill signatures for you, but it’s essential to verify their accuracy. Furthermore, always conduct a thorough review of your return to ensure its completeness and correctness before mailing or e-filing.

10: Missing the Filing Deadline or Not Filing at All

Perhaps one of the most critical mistakes you can make is missing the tax filing deadline or failing to file altogether. Some taxpayers either procrastinate until it’s too late or mistakenly believe they’re exempt from the filing requirement.

The implications of this mistake are substantial. You can face penalties for both failing to file and non-payment, leading to interest charges on your tax balance. In severe cases, you could even be charged with tax evasion.

To steer clear of this significant error, it’s essential to file your taxes on time, even if you’re unable to pay the full amount immediately. If you require additional time, filing for a filing extension by the deadline is an option, but remember to ensure that the taxes are paid. If you find yourself unable to pay the entire amount in one go, it’s recommended to contact the IRS promptly to set up an installment plan.
