common-tax-filing-mistakes-and-how-to-avoid-them

Tax season can be overwhelming, even for the most organized individuals without professional help. With complex tax codes and changing regulations, it’s easy to make tax filing mistakes that could cost you money or delay your refund. Understanding these common pitfalls is the first step toward a smoother tax filing experience.

Are you worried about making errors on your tax return? You’re not alone. Each year, millions of Canadians make preventable mistakes that complicate their tax situation. From simple calculation errors to overlooking valuable deductions, these common tax filing mistakes can lead to penalties, audits, and missed opportunities for savings.

 

Let’s explore the most common tax filing mistakes and, more importantly, how you can avoid them to ensure your tax experience is as stress-free as possible.

This reddit thread discusses the problems with not addressing tax deadlines and the issues it causes.

Now, let’s dive into the nitty-gritty, starting with why filing at the right time is crucial.

Filing Too Early or Too Late

Mistake: Rushing to file your taxes before receiving all necessary documents or waiting until after the deadline.

Filing your taxes without all required forms and documentation is like building a house without all the materials. If you do that, the result will be incomplete and potentially flawed. On the other hand, missing the tax deadline entirely can lead to substantial penalties and interest.

Consequences:

  • Amendments, delays, and potential audits can arise from filing early without complete information
  • Penalties of 5% of unpaid taxes for each month your return is late typically result from filing late
  • Missing out on timely refunds that could help your financial situation

How to Avoid: Create a tax document checklist at the beginning of the year. Mark important dates on your calendar, including the typical arrival times for W-2s, 1099s, and other tax documents. If you know you’ll need more time, file for an extension but always remember, an extension to file is not an extension to pay.

Speaking of key details, let’s discuss the importance of getting your personal information right.

Incorrect or Missing Personal Information

Mistake: Submitting returns with typos in your name, Social Security number, or outdated contact information.

These seemingly common tax filing mistakes can cause major headaches. The IRS matches your personal information against their records, and discrepancies can trigger processing delays or even rejection of your return.

Consequences:

  • You may have to resubmit tax returns if they are rejected
  • Processing of your refund can be delayed
  • You may experience identity verification issues

How to Avoid: Double-check all personal information before submitting your return. Verify that names are spelled correctly, Social Security numbers are accurate, and your current address is listed. This simple verification step can save you weeks of processing time.

With personal information checked, let’s move on to choosing the filing status that works best for you.

Choosing the Wrong Filing Status

Mistake: Selecting an incorrect tax filing status that doesn’t accurately reflect your situation.

Did you know that your filing status affects your standard deduction, tax bracket, and eligibility for certain credits? Choosing between single, married filing jointly, married filing separately, head of household, or qualifying widow(er) has significant financial implications.

Consequences:

  • Overpaying taxes by missing out on beneficial filing statuses
  • Underpaying taxes, which could trigger an audit
  • Missing tax credits only available to certain filing statuses

How to Avoid: Review the IRS guidelines for each filing status annually, as your situation may change year to year. When in doubt, consult with a tax professional who can help determine the most advantageous filing status for your specific circumstances.

Got your filing status sorted? Great! Next up, let’s talk about avoiding those pesky math errors.

Math Errors

Mistake: Making calculation mistakes when adding, subtracting, or transferring figures between forms.

Even in our digital age, mathematical errors remain among the most common tax filing mistakes. A simple transposition or addition error can cascade throughout your return, affecting your tax liability.

Consequences:

  • You may need to correct an incorrect tax assessment
  • You might incur underpayment penalties and interest
  • The IRS may send notices requesting clarification or additional payment

How to Avoid: Use tax preparation software that automatically performs calculations and checks for mathematical inconsistencies. If you’re preparing your return manually, take breaks when needed and review all calculations multiple times before submission.

Math is tricky, but don’t let it trip you up; now onto accurately reporting all that income.

Misreporting Income

Mistake: Failing to report all sources of income on your tax return.

The IRS receives copies of all your income documents W-2s, 1099s, and more. When you omit income, intentionally or not, it raises red flags that could trigger closer scrutiny of your entire return.

Consequences:

  • Potential audit risk increases significantly
  • Penalties of up to 20% of the underpayment for negligence
  • Interest charges on unpaid tax amounts from the due date

How to Avoid: Create a system to track all income sources throughout the year. Keep a folder (physical or digital) for income documentation, and reconcile this against your records before filing. Remember that even small amounts of interest, dividends, or gig economy earnings must be reported.

Income in check? Perfect! Let’s uncover those hidden deductions and credits waiting for you.

Overlooking Deductions and Credits

Mistake: Missing valuable tax deductions and credits that could lower your tax bill or increase your refund.

Tax credits directly reduce your tax liability dollar for dollar, while deductions reduce your taxable income. Failing to claim eligible deductions and credits is like leaving money on the table money that rightfully belongs to you.

Consequences:

  • You might overpay taxes unnecessarily
  • You might miss refundable credits that could provide additional funds
  • Opportunities for tax-advantaged financial planning might be lost

How to Avoid: Research available tax benefits or work with a tax professional who stays current on tax code changes. Common overlooked deductions include student loan interest, self-employment expenses, and charitable contributions. Valuable credits include the Earned Income Tax Credit, Child Tax Credit, and education-related credits.

After you’ve claimed those benefits, make sure your refund lands in the right place by double-checking your bank info.

Incorrect Bank Account Numbers for Direct Deposit

Mistake: Providing inaccurate routing or account numbers for direct deposit refunds.

With most taxpayers now receiving refunds via direct deposit, this tax filing mistake can cause significant delays and complications in receiving your money.

Consequences:

  • Recovering refunds sent to the wrong account may be difficult
  • The IRS sorting out the error will cause processing delays
  • The IRS might need to issue a paper check instead

How to Avoid: Verify bank account details directly from a check or your online banking portal. Triple-check these numbers before submitting, as even a single digit error can direct your refund to someone else’s account.

Almost there! Just don’t forget the final step, remember to sign!

Forgetting to Sign and Date the Return

Mistake: Submitting a paper tax return without signatures or dates.

It may seem obvious, but this oversight is more common than you might think. The IRS considers an unsigned tax return invalid and will not process it until properly signed.

Consequences:

  • Processing of the return cannot begin until you provide a signature
  • The IRS may impose late filing penalties if you submit the signed return after the deadline
  • You may experience delays in receiving refunds or confirmation of tax payments

How to Avoid: Create a final review checklist that includes signature verification. Better yet, consider e-filing your return, which includes electronic signature verification processes that help prevent this mistake.

Signed, sealed, but don’t put it away just yet! Let’s tackle document retention.

Not Retaining Copies of Tax Returns

Mistake: Failing to keep copies of your filed tax returns and supporting documentation.

Your tax return contains valuable financial information that you may need in the future for loan applications, financial planning, or responding to IRS inquiries.

Consequences:

  • You may have difficulty responding to IRS notices without reference materials
  • Preparing future tax returns without historical context can be challenging
  • Providing financial verification for mortgages or other applications might cause problems

How to Avoid: Maintain a tax record filing system, either physically or digitally. Keep returns and supporting documents for at least three years (the standard IRS audit window), though many experts recommend seven years for added security.

Finally, the biggest no-no is not filing at all! Let’s see why that creates huge problems.

Not Filing at All

Mistake: Assuming you don’t need to file because you don’t owe taxes or didn’t earn enough.

One of the most serious tax filing mistakes is failing to file when required. Even if you don’t owe taxes, you might be eligible for refundable credits that could put money in your pocket.

Consequences:

  • Potential refunds (which can only be claimed within three years of the filing deadline) might be missed
  • Non-filing penalties may accumulate if you owe taxes
  • You may create gaps in your tax history that affect Social Security benefits or loan applications

How to Avoid: Understand the filing requirements based on your income, age, and filing status. When in doubt, file a return as there’s no penalty for filing when it wasn’t required, but there can be significant consequences for not filing when necessary.
