The #1 Tax Mistake That Costs Woodbridge Families Hundreds Every Year - And How to Avoid It

Most people in Woodbridge work hard, support their families, and do their best to stay 

financially organized. But every tax season, we see the same tax mistake that could cost 

taxpayers hundreds of dollars in lost refunds, unexpected tax bills, and IRS notices.

The tax mistake that could cost you the most? Not reporting all income, especially side-hustle, gig, and small business earnings.

It may seem like a small oversight, but it's one of the most common issues we help new 

clients correct every year.

Why This Mistake Happens So Often

Most people don’t intentionally leave income off their return. In fact, many taxpayers simply don't realize that all income must be reported, regardless of whether they receive a tax form.

Common reasons include:

• They didn’t receive a 1099  

• They didn’t realize cash payments count as income  

• They assumed small amounts “don’t matter”  

• They used DIY tax software that didn’t ask the right questions  

• They didn’t know the IRS receives copies of many income forms automatically

This tax mistake that could cost you money often starts with a simple misunderstanding. Unfortunately, even a small reporting error can lead to additional taxes, penalties, interest, or a reduced refund.

How a Tax Mistake That Could Cost $900 One Taxpayer

A new client came to us after receiving an IRS notice and wondering why their refund was much smaller than expected.

After reviewing their records, we discovered they had earned approximately $4,000 delivering for DoorDash. Because their earnings fell below the platform's reporting threshold, they assumed they didn't need to report the income.

The tax software they used never asked about gig earnings.

The IRS did.

As a result, their refund was reduced, and they owed approximately $900 in additional taxes and penalties.

The issue was resolved, but this tax mistake could have been avoided with proper tax planning and recordkeeping.

How to Avoid This Tax Mistake

1. Track All income

Keep records of all earnings, including:

• Cash payments

• Venmo and PayPal transfers

• Zelle payments

• Tips

• Freelance work

• Gig app income

2. Save Earnings Statements

If you earn income through platforms such as Uber, Lyft, DoorDash, Instacart, Etsy, or Rover, download and save your annual earnings reports.

Remember, not receiving a tax form does not mean the income isn't taxable.

3. Keep Records of Business Expenses

Many taxpayers overlook deductions that could lower their taxable income.

Common deductible expenses may include:

• Mileage

• Supplies

• Equipment

• Software subscriptions

• Phone and internet usage

• Professional training and certifications

4. Work With a Tax Professional

A qualified tax professional can help ensure your income is reported correctly while identifying deductions that help reduce your tax liability.

The Good News: Reporting Income Can Unlock Valuable Deductions

Many people assume that reporting additional income will automatically increase their tax bill.

In reality, properly reporting gig or self-employment income may allow you to claim deductions such as:

• Business mileage

• Home office expenses

• Equipment purchases

• Cell phone usage

• Internet costs

• Software subscriptions

• Professional education 

These deductions can reduce taxable income and help you keep more of your hard-earned money.

Final Thoughts on the Tax Mistake That Could Cost You

The tax mistake that could cost you the most this year may be as simple as forgetting to report income from a side hustle, gig job, or small business activity.

Taking the time to track your earnings, keep good records, and file an accurate return can help you avoid IRS notices, reduce stress, and protect your refund.
