Understanding how to read a tax return isn’t just for accountants—it’s a must-have skill for anyone who files taxes. Whether you’re a small business owner, freelancer, or someone who just wants to avoid IRS penalties, reading and checking your tax return for errors could save you money.
At Simplicity Financial, we help clients make sense of their finances through expert tax preparation outsourcing, outsourced bookkeeping, and fractional CFO services. But even with professional help, it’s good to know what’s in your tax return so you can spot common mistakes and maximize deductions.
Why Knowing How to Read a Tax Return Matters
If you’re trying to prepare tax returns for the first time or just learning more about your personal finances, it’s common to feel worried about making mistakes. Simple mistakes—like misreporting income or misunderstanding tax credits—can cost you hundreds or even thousands of dollars.
Even worse, not reviewing your tax return properly could mean you’re leaving money on the table or even overpaying taxes that you don’t actually owe!
Key Tax Documents You Need to Know
Before we break down how to read a tax return, let’s look at the essential documents that you or your tax professional should review:
- Form 1040 (U.S. Individual Income Tax Return) – The main tax form that summarizes your total income, deductions, and tax payments.
- W-2 (Wage & Tax Statement) – A summary of your employment income and taxes withheld.
- 1099 Forms – Used for freelancers, contractors, and investments, including 1099-NEC (self-employment), 1099-DIV (dividends), and 1099-S (real estate sales).
- Schedule C – Reports business income and expenses for self-employed individuals.
- Schedule A (Itemized Deductions) – Details deductible expenses like mortgage interest, medical expenses, and charitable donations.
How to Read Tax Returns Like a Pro
1. Start with the Basics: Checking Personal Information
One of the most overlooked tax return mistakes is incorrect personal details. Before diving into the numbers, make sure:
✅ Your name and Social Security Number (SSN) are correct
✅ Your filing status (Single, Married, Head of Household) is accurate
✅ Your dependent information is correct (if applicable)
Even a small mistake here can delay your refund or cause incorrect tax calculations.
2. Review Your Total Income and Reported Earnings
Look at Line 1 of Form 1040—this is your total income before any deductions or credits. Common mistakes include:
❌ Missing income – If you worked multiple jobs, make sure all W-2s and 1099s are included
❌ Incorrect self-employment earnings – If you’re a freelancer, double-check your reported income against invoices and bank deposits
❌ Capital gains/losses – If you sold stocks or real estate, confirm that investment gains or losses are correctly reported on Schedule D
Spotting Common Errors on a Tax Return
3. Understand Deductions & Credits
Deductions and credits can lower your tax bill—but only if claimed correctly. The IRS rejects thousands of returns due to incorrect or missing credits.
- Standard Deduction vs. Itemized Deductions – Did you choose the right one? Most taxpayers take the standard deduction, but if your mortgage interest, medical expenses, or charitable donations are high, you may benefit from itemizing.
- Earned Income Tax Credit (EITC) – Check if you qualify! Many eligible taxpayers miss out on thousands of dollars in credits.
- Education Tax Credits – If you paid for college (or a dependent did), make sure you’re claiming the American Opportunity Credit or Lifetime Learning Credit.

What Happens if Your Tax Return Has Errors?
Even a small mistake—like transposing numbers—can trigger an IRS notice. If you find an error after filing, you may need to file an amended return (Form 1040-X).
Common Consequences of Tax Return Errors:
🚨 Delayed refunds – The IRS will hold your return if numbers don’t match official records
🚨 Penalties & interest – If errors result in underpayment, the IRS may charge interest and penalties
🚨 Audits – While rare, a major discrepancy could increase your risk of an audit
To avoid these headaches, double-check your return—or let the experts at Simplicity Financial handle it for you!

How to Read a Small Business Tax Return and Avoid Pitfalls
If you own a small business, understanding how to read a small business tax return is crucial. Whether you file a Schedule C (for sole proprietors) or Form 1120 (for corporations), these documents provide insights into your business’s financial health, tax liability, and potential savings.
🔍 Key Areas to Review in a Business Tax Return:
✔️ Revenue and Expenses:
Your business tax return should accurately reflect gross income and deductible expenses. Errors in revenue reporting or misclassified expenses could lead to unnecessary tax liability or red flags for an IRS audit.
✔️ Depreciation and Asset Deductions:
If your business owns equipment, vehicles, or property, you may be eligible for depreciation deductions. The IRS requires that these deductions be reported on Form 4562—but incorrect calculations could mean losing out on significant tax savings.
✔️ Payroll Taxes and Employee Compensation:
Business owners who hire employees or independent contractors need to verify payroll tax filings. Ensure Forms W-2 and 1099 match what’s reported on your Form 941 (for employment taxes) or Form 940 (for unemployment taxes).
✔️ Business Tax Credits:
Many small business owners miss out on valuable tax credits, such as the Small Business Health Care Tax Credit or the Employee Retention Credit. A tax professional can help ensure you’re maximizing deductions and credits while staying compliant.
💡 Even small reporting errors can lead to IRS audits, missed deductions, or penalties. If tax returns feel overwhelming, our outsourced bookkeeping services can help streamline recordkeeping so your tax filings stay accurate year-round.
How to Read a Joint Tax Return and What to Look For
Filing a joint tax return can offer higher deductions and simplify tax filings for married couples, but it also means both spouses are responsible for each other’s tax liabilities.
🔍 Common Mistakes in Joint Tax Returns:
✔️ Misreporting Income
Ensure that both spouses’ W-2s, 1099s, and investment income are correctly reported. Underreporting or omitting income can trigger an IRS notice or an unexpected tax bill.
✔️ Overlooking Deductions and Credits
Couples may qualify for higher deductions when filing jointly. Some tax benefits include:
- The Child Tax Credit (CTC)
- The Earned Income Tax Credit (EITC)
- The Student Loan Interest Deduction
Review deductions carefully to ensure you’re not leaving money on the table.
✔️ Choosing the Wrong Filing Status
While most married couples file jointly, Married Filing Separately (MFS) can sometimes reduce tax liability—especially if one spouse has high medical expenses, student loans, or deductions limited by adjusted gross income (AGI).
💡 A joint tax return mistake could affect both spouses—even if only one person made the error. If you’re unsure whether Married Filing Jointly (MFJ) or Married Filing Separately (MFS) is better for your situation, our remote tax preparation services ensure you get the best filing strategy.
