Tax Return Checkpoint: 12 Things to Verify Before You File (Avoid Delays & Costly Mistakes)

Financial Horizons: Insights for Building Wealth and Securing Your Legacy 

By Dr. Jose G. Cardenas, Chief Tax Strategist at The C & R Group, LLC

Let’s be honest—most taxpayers don’t get into trouble because they didn’t file.

They get into trouble because they filed too quickly without verifying the details.

At this stage of tax season, the difference between a smooth filing and a frustrating one often comes down to one thing: verification.

This is your March 23, 2026 article in our April 15 Finish Strong campaign, and today’s mission is simple:

Run a final checkpoint before filing to avoid delays, missed deductions, and IRS issues.

Because once you hit submit, fixing mistakes becomes harder.

Why This Checkpoint Matters

A tax return pulls together multiple moving parts:

• income reporting
• deductions
• credits
• dependents
• payments and refunds

If even one piece is off, it can result in:

• delayed refunds
• IRS notices
• amended returns
• or overpaying taxes

A checkpoint is not extra work—it’s risk management.

The 12-Point Tax Return Verification Checklist

Before you file, take a few minutes and walk through these:

1. All Income Is Reported

Confirm every source of income is included:

• W-2s
• 1099s (NEC, K, INT, DIV, R)
• K-1s
• investment income

👉 If the IRS receives it, your return should reflect it.

2. Personal Information Is Accurate

Verify:

• names match Social Security records
• SSNs are correct
• address is current

Small errors here can delay processing.

3. Filing Status Is Correct

Your filing status affects your entire return. Make sure it’s accurate and supported.

4. Dependents Are Verified

Confirm:

• eligibility
• correct SSNs
• no duplicate claims

Dependent errors are one of the most common filing issues.

5. Bank Information Is Correct

Double-check routing and account numbers for direct deposit.

👉 One wrong digit = delayed refund.

6. Deductions Are Fully Captured

Review for missed opportunities:

• mortgage interest
• charitable contributions
• student loan interest
• business expenses

7. Credits Are Properly Applied

Make sure eligible credits are included and documented:

• child-related credits
• education credits
• earned income credit

8. Business / Side Hustle Income Is Clean

If applicable, confirm:

• all income is reported
• expenses are categorized correctly
• mileage logs are included

9. Estimated Payments Are Included

If you made quarterly payments, ensure they are reflected in your return.

Missing these can make it look like you owe more than you do.

10. Retirement Contributions Are Considered

Ask yourself:

• Did I contribute to an IRA?
• Can I still contribute before April 15?

This could still reduce your tax bill.

11. Refund or Balance Due Makes Sense

Compare to last year:

• Is the result reasonable?
• Is there a major difference that needs explanation?

If something feels off—it probably is.

12. All Required Forms Are Included

Make sure you are not missing:

• K-1s
• late 1099s
• supporting schedules

Filing too early can create problems later.

The Biggest Mistake at This Stage

The biggest mistake right now is filing under pressure instead of filing with clarity.

That pressure leads to:

• skipped reviews
• missing documents
• incorrect assumptions
• unnecessary errors

A few extra minutes today can prevent weeks of frustration later.
