What to check first (before you act)

Your Tax Records

Before filing, gather all necessary documentation. This includes W-2s from employers, 1099s for freelance income or other payments, receipts for deductible expenses, and any statements related to investments or other financial activities. Ensure you have records for at least three years, as this is the typical period the IRS can audit.

Your Filing History

Review your past tax returns for any discrepancies or areas that might have attracted attention. If you’ve had an audit before, understand why it occurred and ensure you’ve corrected any issues. Consistency in your filing year after year can be beneficial.

Eligibility for Deductions and Credits

Double-check that you meet all the requirements for any deductions or credits you plan to claim. The IRS often targets returns with unusually high deductions or credits relative to income. Misunderstanding or misapplying tax laws is a common cause of penalties.

Step-by-step (simple workflow)

1. Gather All Income Documents

What to do: Collect all W-2s, 1099s (for freelance work, interest, dividends, etc.), and any other statements reporting income.
What “good” looks like: You have a complete list of all income sources and the amounts reported to you.
A common mistake and how to avoid it: Forgetting to report cash income or income from side hustles. Avoid this by diligently tracking all earnings, no matter how small or how they are paid.

2. Collect Expense Records

What to do: Organize receipts, invoices, and statements for any expenses you plan to deduct. This includes business expenses, medical costs, charitable donations, and more.
What “good” looks like: You have organized documentation to support every deduction you intend to claim.
A common mistake and how to avoid it: Claiming deductions without proper substantiation. Avoid this by keeping receipts and records for everything you deduct.

3. Choose Your Filing Method

What to do: Decide whether to use tax software, hire a tax professional, or file yourself using paper forms.
What “good” looks like: You’ve selected a method that suits your tax situation’s complexity and your comfort level with tax preparation.
A common mistake and how to avoid it: Using a method that’s too complex for your situation, leading to errors. For example, using basic software for a business with many complex deductions.

4. Accurately Report All Income

What to do: Enter all income from all sources onto your tax return. This includes wages, freelance pay, investment earnings, and any other taxable income.
What “good” looks like: Your reported income matches the amounts on your W-2s and 1099s, and you’ve included any unreported income.
A common mistake and how to avoid it: Omitting income, especially from side jobs or cash payments. Always report 100% of your earnings.

5. Claim Only Eligible Deductions and Credits

What to do: Carefully review the IRS guidelines for each deduction and credit you plan to claim to ensure you qualify.
What “good” looks like: You understand the eligibility rules and have documentation to support your claims.
A common mistake and how to avoid it: Claiming deductions or credits you don’t qualify for, often due to misunderstanding the rules. Stick to the IRS guidelines.

6. Double-Check Your Return

What to do: Before submitting, carefully review your entire tax return for mathematical errors, transposed numbers, or missing information.
What “good” looks like: Your return is accurate, complete, and free of obvious mistakes.
A common mistake and how to avoid it: Simple data entry errors or miscalculations. Take your time, use the review features in tax software, or have someone else look it over.

7. File On Time

What to do: Submit your tax return by the official deadline (typically April 15th, unless extended).
What “good” looks like: Your return is filed by the due date, avoiding late-filing penalties.
A common mistake and how to avoid it: Missing the deadline. If you can’t file on time, file for an extension, but remember this is an extension to file, not an extension to pay.

8. Pay Any Taxes Owed Promptly

What to do: If you owe taxes, make your payment by the deadline.
What “good” looks like: Your tax liability is fully paid by the due date.
A common mistake and how to avoid it: Not paying taxes owed by the deadline. This accrues interest and penalties.

9. Respond to IRS Notices

What to do: If you receive any correspondence from the IRS, read it carefully and respond promptly.
What “good” looks like: You understand the notice and take the required action within the specified timeframe.
A common mistake and how to avoid it: Ignoring IRS notices. This can escalate the situation and lead to more severe penalties.

10. Keep Records for at Least Three Years

What to do: Store copies of your tax returns and all supporting documentation for at least three years from the date you filed.
What “good” looks like: You have easy access to your tax records if the IRS requests them or if you need them for future reference.
A common mistake and how to avoid it: Discarding records too soon. The IRS has a statute of limitations for audits, typically three years.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Omitting income	Underpayment penalties, interest charges, potential audit	Amend your return and pay the taxes owed; report all income going forward.
Claiming ineligible deductions/credits	Penalties, interest, potential audit, disallowed deductions	Remove the ineligible items, amend your return if already filed, and ensure you understand eligibility rules for future filings.
Mathematical errors	Incorrect tax liability (over or underpayment), potential penalties	Double-check all calculations; use tax software with built-in error checking.
Filing late without an extension	Late-filing penalties	File an extension if you anticipate missing the deadline; file as soon as possible.
Not paying taxes owed by the deadline	Late-payment penalties and interest	Pay as much as you can by the deadline; explore payment options with the IRS if you can’t pay in full.
Poor record-keeping	Inability to substantiate deductions, leading to disallowance and penalties	Implement a system for organizing and storing receipts and financial documents.
Not reporting cash income	Underpayment penalties, interest, potential audit	Track all cash income meticulously and report it on your return.
Ignoring IRS notices	Escalation of issues, increased penalties, potential legal action	Read notices carefully, understand the request, and respond within the specified timeframe, ideally with professional help.
Using incorrect tax forms	Rejection of return, missed deadlines, incorrect tax calculations	Ensure you are using the most current and appropriate forms for your tax situation.

Decision rules (simple if/then)

• If you received more than one type of income (e.g., W-2 and 1099), then be extra diligent in reporting all sources because the IRS has systems to match reported income.
• If you are self-employed or have significant business expenses, then consider hiring a tax professional because their expertise can help ensure accuracy and identify all eligible deductions.
• If you are unsure about the eligibility for a specific deduction or credit, then research the IRS guidelines thoroughly or consult a tax professional because claiming ineligible items can lead to penalties.
• If you received an IRS notice, then do not ignore it because timely responses are crucial to resolving issues and avoiding further complications.
• If you made a mistake on a previously filed return, then file an amended return (Form 1040-X) promptly because correcting errors can minimize penalties and interest.
• If you anticipate owing a significant amount of tax, then consider adjusting your W-4 withholding or making estimated tax payments because this can help avoid a large tax bill and penalties at year-end.
• If you have a complex tax situation (e.g., investments, foreign income, rental properties), then use tax software designed for complexity or a professional because simple software may not handle all nuances, increasing the risk of errors.
• If you are claiming large or unusual deductions, then ensure you have robust documentation to support them because these are often red flags for audits.
• If you are a gig worker or freelancer, then set aside a portion of each payment for taxes because this helps ensure you have funds available when taxes are due.
• If you have a side business, then keep separate business and personal finances because this makes tracking income and expenses for tax purposes much easier and clearer.

FAQ

What is the most common reason for an IRS audit?

The most common reasons include claiming large or unusual deductions, having significant income from sources that are not typically taxed (like cash), or errors that don’t seem to be simple typos.

How long does the IRS typically keep records of my tax filings?

Generally, the IRS recommends keeping records for at least three years from the date you filed your return. In some cases, like if you underreport income by 25% or more, they can go back six years.

What are the penalties for filing taxes late?

The penalty for filing late is usually 5% of the unpaid taxes for each month or part of a month that a tax return is late, up to a maximum of 25%. There’s also a penalty for not paying on time, which is 0.5% of unpaid taxes per month, capped at 25%.

What is the difference between an audit and an IRS notice?

An audit is a more thorough review of your tax return, often involving an in-person meeting or extensive document submission. An IRS notice is a letter informing you of a specific issue, such as a discrepancy or a penalty, and usually requires a specific action or response.

Can I avoid penalties if I can’t afford to pay my taxes right away?

Yes, the IRS offers payment plans and an Offer in Compromise program. It’s crucial to communicate with the IRS and make arrangements; ignoring the debt will only increase penalties and interest.

Is it better to use tax software or a tax professional?

For simple tax returns, tax software can be efficient and cost-effective. For more complex situations, such as self-employment, investments, or significant life changes, a tax professional can provide expertise and help identify all eligible deductions, potentially saving you money and avoiding errors.
