Tax season can be stressful—even for people with relatively straightforward finances. Between gathering documents, understanding changing tax rules, and trying to maximize deductions, it’s easy to make mistakes that lead to delays, missed savings opportunities, or even IRS notices.

For individuals in Brentwood, proper tax preparation is about more than filing on time. It’s about filing accurately, understanding your options, and avoiding costly errors that can impact your finances.

In this guide, we’ll cover the most common mistakes people make during individual tax preparation in Brentwood and what you can do to avoid them.

Why Accurate Tax Preparation Matters

Filing your taxes correctly helps you:

• Avoid IRS penalties and interest
• Prevent delays in receiving refunds
• Reduce audit risk
• Claim every deduction and credit you qualify for
• Create a stronger long-term financial plan

Even small errors can create unnecessary complications.

1. Missing Income Sources

One of the most common tax filing mistakes is forgetting to report all taxable income.

Many taxpayers remember their W-2 but overlook:

• 1099 freelance income
• Interest income (Form 1099-INT)
• Dividend income (Form 1099-DIV)
• Investment sales (Form 1099-B)
• Rental income
• Side business income
• Online platform income

The IRS receives copies of most tax documents directly from payers.

How to avoid this:

Create a checklist of every income source before filing and compare it against the tax forms you receive.

2. Choosing the Wrong Filing Status

Your filing status affects:

• Tax brackets
• Standard deduction amount
• Eligibility for tax credits

Common filing statuses include:

• Single
• Married Filing Jointly
• Married Filing Separately
• Head of Household
• Qualifying Surviving Spouse

Common mistake:

People often assume Head of Household applies automatically when supporting children—it does not.

How to avoid this:

Review IRS filing status requirements each year, especially after life changes.

3. Missing Tax Deductions

Many taxpayers leave money on the table by overlooking deductions.

Potential deductions may include:

Above-the-line deductions:

• Traditional IRA contributions
• Student loan interest
• Health Savings Account (HSA) contributions
• Self-employed health insurance

Itemized deductions:

• Mortgage interest
• Charitable contributions
• State and local taxes (subject to limits)
• Medical expenses (subject to thresholds)

How to avoid this:

Don’t rely on memory—review expense records and prior returns.

4. Overlooking Valuable Tax Credits

Tax credits are especially valuable because they reduce taxes dollar-for-dollar.

Common credits include:

• Child Tax Credit
• Earned Income Tax Credit (EITC)
• Child and Dependent Care Credit
• Education credits
• Energy efficiency credits

Common mistake:

Many taxpayers incorrectly assume they earn too much or don’t qualify.

How to avoid this:

Review eligibility annually because income thresholds and rules change.

5. Incorrect Banking Information

This may sound simple, but entering the wrong account number can delay refunds.

Common issues:

• Incorrect routing number
• Closed bank accounts
• Typographical errors

How to avoid this:

Double-check all banking information before submitting.

6. Math and Data Entry Errors

Even with software, mistakes happen.

Common examples:

• Incorrect Social Security numbers
• Transposed numbers
• Entering deductions twice
• Missing decimal places

How to avoid this:

Review your return line-by-line before filing.

7. Forgetting Estimated Tax Payments

If you:

• Freelance
• Own a business
• Receive investment income
• Have rental properties

You may owe quarterly estimated taxes.

Common mistake:

Forgetting to include estimated payments already made during the year.

Result:

You could accidentally overpay.

How to avoid this:

Keep a record of all estimated tax payments and confirm they appear on your return.

8. Ignoring Retirement Tax Planning

Retirement contributions can reduce taxable income significantly.

Examples:

• Traditional IRA
• SEP IRA
• Solo 401(k)

Common mistake:

Waiting until filing season and missing contribution deadlines.

How to avoid this:

Review retirement opportunities before year-end.

9. Filing Too Early or Too Late

Filing too early can cause problems if tax documents arrive later.

Filing too late can trigger:

• Failure-to-file penalties
• Interest charges
• Delayed refunds

How to avoid this:

Wait until:

• All tax forms arrive
• Income records are complete
• You’ve reviewed deductions thoroughly

10. Assuming Tax Software Catches Everything

Tax software is helpful—but it’s only as good as the information entered.

Software cannot always:

• Identify missing documents
• Suggest advanced planning opportunities
• Interpret unusual situations accurately

Examples include:

• Multiple income streams
• Investments
• Divorce
• Real estate transactions
• Self-employment income

Special Considerations for Brentwood Residents

People living in Brentwood benefit from living in Tennessee, which does not impose state tax on earned income.

However, taxpayers still need to plan for:

• Federal income taxes
• Capital gains and investment reporting
• Self-employment taxes
• Property tax considerations
• Business-related tax obligations (if applicable)

This makes proactive preparation especially valuable.

Signs You Should Get Professional Tax Help

Consider professional support if you:

• Have multiple income sources
• Own rental property
• Changed jobs during the year
• Started freelancing
• Received an IRS notice
• Sold investments
• Own a small business

Professional guidance often identifies savings that exceed the preparation cost.

Simple Tax Preparation Checklist

Before filing, confirm you have:

✅ W-2s and 1099s
✅ Investment statements
✅ Mortgage interest statements
✅ Donation receipts
✅ Retirement contribution records
✅ Estimated tax payment records
✅ Identity and banking information
✅ Prior year tax return
