Filing a Simple Tax Return: An Easy-to-Follow Process

Quick answer

• Understand your filing status.
• Gather all income documents (W-2s, 1099s).
• Review potential deductions and credits.
• Choose a filing method (DIY software or tax professional).
• Double-check all information before submitting.
• File by the tax deadline or request an extension.

What to check first (before you file or change withholding)

Filing Status

Your filing status is the first major decision when preparing your taxes. It affects your tax rate, standard deduction, and eligibility for certain credits. The most common statuses are Single, Married Filing Separately, Married Filing Jointly, Head of Household, and Qualifying Widow(er).

• What to check: Determine which status accurately reflects your personal circumstances as of December 31st of the tax year.
• Good looks like: You’ve chosen the status that provides the most tax benefit or is legally required based on your situation.
• Common mistake: Using the wrong filing status, which can lead to overpaying taxes or facing penalties later. Always verify your eligibility for statuses like Head of Household.

Income Sources

Accurately reporting all income is crucial. This includes wages, self-employment income, interest, dividends, capital gains, and any other earnings.

• What to check: Collect all relevant tax forms, such as W-2s from employers, 1099 forms for freelance or investment income, and statements for interest and dividends.
• Good looks like: You have documentation for every dollar earned during the tax year.
• Common mistake: Forgetting to report certain income, especially from side gigs or investments, which can trigger IRS notices.

Withholding or Estimated Payments

For employees, taxes are typically withheld from each paycheck. If you have income from other sources, like self-employment or investments, you may need to make estimated tax payments.

• What to check: Review your W-4 form with your employer if your income or life situation has changed significantly. For other income, estimate your tax liability and make quarterly payments if required.
• Good looks like: Your withholding or estimated payments are aligned with your expected tax liability, aiming to avoid a large tax bill or penalty.
• Common mistake: Under-withholding taxes throughout the year, leading to a surprise tax bill and potential underpayment penalties.

Deductions and Credits

Deductions reduce your taxable income, while credits directly reduce your tax liability. Understanding what you qualify for can significantly lower your tax burden. Common deductions include those for student loan interest or certain retirement contributions. Common credits include the Child Tax Credit or education credits.

• What to check: Familiarize yourself with common deductions and credits and gather any documentation needed to claim them. This might include receipts for charitable donations or records of education expenses.
• Good looks like: You’ve identified all eligible deductions and credits and have the necessary proof to support your claims.
• Common mistake: Missing out on valuable deductions and credits due to lack of awareness or not having proper documentation.

Deadlines and Extensions

The primary tax filing deadline in the U.S. is typically April 15th. If this date falls on a weekend or holiday, it shifts to the next business day.

• What to check: Be aware of the official deadline for the current tax year. If you anticipate needing more time, you can file for an extension, which usually grants an additional six months.
• Good looks like: You file your return by the deadline or have filed for an extension and are working towards submitting it by the extended due date.
• Common mistake: Missing the filing deadline without requesting an extension, which can result in failure-to-file penalties.

Step-by-step (simple workflow)

1. Gather Your Documents:

• What to do: Collect all income statements (W-2s, 1099s), records of expenses for deductions, and any other relevant tax forms.
• Good looks like: You have all necessary paperwork organized and ready.
• Common mistake: Starting the filing process without all documents, leading to delays and incomplete information. Avoid this by making a checklist of required forms.

2. Choose Your Filing Status:

• What to do: Determine your filing status based on your marital and family situation as of December 31st.
• Good looks like: You’ve selected the most advantageous or accurate status for your circumstances.
• Common mistake: Selecting an incorrect status, such as Head of Household when you don’t qualify, which can lead to issues.

3. Calculate Your Income:

• What to do: Sum up all your taxable income from all sources.
• Good looks like: Your total income accurately reflects all earnings reported on your documents.
• Common mistake: Omitting income from side jobs or investments. Double-check all your 1099s and W-2s.

4. Determine Your Deductions:

• What to do: Identify and calculate any deductions you are eligible for, such as the standard deduction or itemized deductions if they exceed the standard amount.
• Good looks like: You’ve chosen the deduction method that provides the greatest tax benefit.
• Common mistake: Forgetting to claim eligible deductions or not having proof for itemized deductions. Keep receipts for potential itemized deductions.

5. Identify Eligible Credits:

• What to do: Review tax credits you may qualify for, like those for education, children, or energy-efficient home improvements.
• Good looks like: You’ve claimed all credits that reduce your tax liability.
• Common mistake: Overlooking credits that could significantly lower your tax bill. Research common credits like the Earned Income Tax Credit or Child Tax Credit.

6. Select a Filing Method:

• What to do: Decide whether to use tax software, a tax preparer, or paper forms. For simple returns, tax software is often efficient.
• Good looks like: You’ve chosen a method that suits your comfort level with tax preparation and the complexity of your return.
• Common mistake: Using a method that is too complex for your situation, leading to errors, or not taking advantage of free filing options if eligible.

7. Complete Your Tax Forms:

• What to do: Accurately enter all your financial information into your chosen filing method.
• Good looks like: All fields are filled out correctly and consistently with your supporting documents.
• Common mistake: Typos or transposed numbers, especially Social Security numbers or income figures. Proofread carefully.

8. Review Your Return:

• What to do: Thoroughly check your entire tax return for accuracy, ensuring all calculations are correct and all information matches your documentation.
• Good looks like: You’ve caught and corrected any potential errors before submission.
• Common mistake: Submitting a return with errors, which can lead to delays, audits, or penalties. A second review, or having someone else look it over, can help.

9. File Your Return:

• What to do: Submit your completed tax return electronically or by mail by the tax deadline.
• Good looks like: Your return has been successfully filed and you have a confirmation.
• Common mistake: Filing late without an extension. Mark your calendar with the tax deadline.

10. Pay Any Tax Owed or Receive Your Refund:

• What to do: If you owe taxes, make a payment. If you are due a refund, ensure your direct deposit information is correct.
• Good looks like: Your tax payment is made on time, or your refund is on its way.
• Common mistake: Not paying taxes owed by the deadline, which incurs penalties and interest. Set up payment reminders.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Incorrect Filing Status	Overpaying taxes or claiming ineligible benefits.	Re-file your return with the correct filing status.
Forgetting to Report Income	Underpayment penalties, interest, and potential audits.	Amend your return to include the forgotten income and pay any additional tax owed.
Math Errors	Delayed refunds, incorrect tax liability, or notices from the IRS.	If you catch it before filing, correct it. If after filing, amend your return.
Incorrectly Claiming Deductions/Credits	IRS notices, penalties, and interest.	Amend your return to remove the ineligible deduction/credit and pay any additional tax. Keep good records to support claims.
Missing the Filing Deadline	Failure-to-file penalties (which can be severe) and interest on unpaid tax.	File as soon as possible, even if late, and pay any tax owed. Request an extension if needed to avoid penalties.
Not Paying Taxes Owed by the Deadline	Failure-to-pay penalties and interest on the amount owed.	Pay the full amount owed as soon as possible. The IRS may offer payment plans if you cannot pay the full amount.
Incorrect Social Security Numbers	Delayed refunds or IRS notices for both you and the individuals listed.	Double-check all Social Security numbers before filing. If incorrect, amend your return.
Typos in Bank Account Information (Refunds)	Delayed refunds or refunds sent to the wrong account.	Carefully verify your bank account and routing numbers. If a refund was sent to the wrong account, contact your bank and the IRS.
Not Keeping Records	Inability to support deductions or credits if audited, leading to disallowance.	Reconstruct records where possible. For future returns, establish a system for organizing and storing tax-related documents for at least three years.
Using the Wrong Tax Form	Inaccurate filing, potential rejection of return, or penalties.	Ensure you are using the correct tax forms for your specific income and situation. Tax software helps with this.

Decision rules (simple if/then)

• If you received income from more than one employer or as a freelancer, then you will likely receive multiple W-2 or 1099 forms.
• If your income consists solely of wages from one employer and you don’t plan to itemize deductions, then filing a simple tax return with the standard deduction is likely straightforward.
• If you are married, then you can choose to file jointly or separately; filing jointly is often more beneficial but depends on your specific financial situation.
• If you have significant medical expenses, charitable donations, or state and local taxes that exceed certain thresholds, then itemizing deductions might be more advantageous than taking the standard deduction.
• If you have dependents, then you may be eligible for credits like the Child Tax Credit, which can significantly reduce your tax liability.
• If you received unemployment benefits, then these are taxable income and must be reported on your tax return.
• If you had investments that generated dividends or capital gains, then you will receive Form 1099-DIV or Form 1099-B, respectively, which you must report.
• If you owe more than $1,000 in tax when you file, then you may be subject to underpayment penalties if you didn’t have enough taxes withheld or pay enough estimated taxes throughout the year.
• If you expect to owe taxes and don’t want a large bill next year, then adjust your W-4 with your employer to increase withholding or make estimated tax payments.
• If you are self-employed, then you are generally required to pay self-employment tax (Social Security and Medicare) and estimated income tax quarterly.
• If you cannot file by the April deadline, then filing Form 4868 grants an automatic six-month extension to file, but not to pay any tax owed.

FAQ

Q: What is a simple tax return?

A simple tax return generally involves common income sources like wages, unemployment benefits, and standard deductions, without complex investments, business income, or many itemized deductions.

Q: Do I need to file if my income is low?

You may not be required to file if your gross income is below a certain threshold, but you should file if you want to claim a refund for withheld taxes or qualify for certain tax credits. Check IRS guidelines for filing requirements.

Q: What’s the difference between a deduction and a credit?

A deduction reduces your taxable income, lowering the amount of income subject to tax. A credit directly reduces the amount of tax you owe, dollar for dollar.

Q: How do I know if I should itemize deductions or take the standard deduction?

Compare the total of your potential itemized deductions (like mortgage interest, state and local taxes, charitable contributions) to the standard deduction amount for your filing status. Choose whichever is higher.
