Tax season is often framed around what to do with your refund,but many of the most costly mistakes happen before you ever submit your return. From waiting too long to file to overpaying for tax preparation, the decisions you make early can impact both your finances and your peace of mind.
At Members Exchange Federal Credit Union (MEFCU), we’re committed to helping our members make confident financial decisions. With a little preparation and awareness, you can avoid common tax season mistakes and keep more of your hard-earned money.
What Are the Most Common Tax Season Mistakes to Avoid?
Many tax filing mistakes are simple,but they can lead to delays, added stress, or even extra costs.
Common errors include:
- Entering incorrect Social Security numbers
- Misspelling names
- Choosing the wrong filing status
- Making calculation mistakes
- Using incorrect bank account information for direct deposit
Even small oversights like forgetting to sign your return can cause issues.
Beyond technical errors, there are also financial mistakes people make during tax season, such as waiting until the last minute, overpaying for preparation, or assuming all filing options cost the same. These decisions can increase costs and make the process more stressful than it needs to be.

What Should I Do Before Filing My Taxes?
Taking time to get organized before filing can make the entire process smoother.
Start by gathering important documents, including:
- W-2s and 1099 forms
- Social Security numbers for you and your dependents
- Records for deductions and credits
- Prior-year tax returns
Before you submit your return:
- Double-check your personal information
- Confirm your filing status
- Review your bank account and routing numbers
- Carefully look over your return for accuracy
These simple steps can help you avoid delays and reduce the likelihood of costly corrections later.
Is It Better to File Taxes Early or Wait?
For most people, filing early is the better option.
Filing early can:
- Help you receive your refund sooner
- Reduce the risk of identity theft-related filing issues
- Give you time to correct any errors before the deadline
Waiting until the last minute often adds unnecessary pressure. As demand increases closer to Tax Day, both tax software pricing and professional preparation fees may rise, meaning you could end up paying more.
What Happens If I Wait Until the Last Minute to File My Taxes?
Waiting too long can lead to rushed decisions and avoidable mistakes.
When you file at the last minute, you may:
- Feel stressed and more likely to overlook details
- Pay higher prices for tax preparation
- Have limited access to professional assistance
If you miss the deadline and owe taxes, penalties and interest may apply. It’s also important to remember that filing an extension does not extend your payment deadline and that ultimately any taxes owed are typically still due on time.
How Do I Choose Between Tax Software and a Tax Professional?
Choosing the right filing method depends on your individual situation.
Tax software may be a good fit
- Your return is relatively simple
- You’re comfortable entering your own information
- You’re looking for a lower-cost option
A tax professional may be the better choice if:
- You have multiple income sources
- You’re self-employed
- Your return is more complex
- You want added guidance and peace of mind
Taking time to choose the right option can help you avoid errors and unnecessary expenses.

How Can I Avoid Overpaying for Tax Preparation?
Tax preparation costs can vary widely, so it’s important to compare your options.
To avoid overpaying:
- Start early before prices increase
- Compare multiple providers or software options
- Ask for full pricing upfront
- Watch for extra fees, such as add-ons or state filing costs
Understanding what you’re paying for helps ensure you’re getting the right value for your needs.
