As a tax preparer, ensuring that your clients’ tax returns are accurate and compliant with IRS rules is crucial. However, there are times when a tax return may contain information that can trigger IRS scrutiny; let’s call these red flag warnings. These red flag warnings can lead to IRS audits, penalties, or other issues for your client if not addressed early.
In this article, we’ll take a closer look at common red flag warnings on tax returns, how to spot them, and how you can properly warn your clients to avoid future problems with the IRS.
Common Red Flag Warnings on Tax Returns
Here are some of the most common red flags that can trigger an IRS audit or further investigation:
- Unusually High Deductions
- Red Flag: Claiming unusually high deductions in relation to income. Such as large charitable donations, medical expenses, or business-related expenses. These can all attract IRS attention.
- How to Address It: Ensure all deductions are reasonable and supported by documentation. Advise clients to keep receipts and backup documentation, especially when claiming large amounts for deductions like charitable donations or medical expenses.
- Discrepancies Between Reported Income and Lifestyle
- Red Flag: If a client reports a low income but exhibits signs of a higher standard of living, such as expensive purchases or vacations, it could raise suspicion. If a client is bragging about buying a yacht, but they are only reporting $50,000 of income, Houston, we have a problem.
- How to Address It: Make sure the income reported is accurate and aligned with the client’s lifestyle. Encourage transparency, and advise clients to keep their financial records in order.
- Self-Employed Income and Expenses
- Red Flag: Tax returns from self-employed individuals are frequently flagged, especially when business expenses are high relative to reported income.
- How to Address It: Verify that business expenses are legitimate and substantiated by receipts, invoices, and bank records. Encourage self-employed clients to maintain accurate and detailed records of their business activities.
- Claiming Dependents Who Don’t Live in the Household
- Red Flag: Claiming dependents who don’t meet the IRS’s eligibility criteria, or who don’t live with the taxpayer for the majority of the year, can trigger an audit.
- How to Address It: Verify that all dependents meet the IRS’s rules for claiming dependents. In cases of divorce, ensure that the correct parent is claiming the dependent, based on custody agreements.
- Round Numbers on Income or Deductions
- Red Flag: Reporting rounded figures for income, deductions, or expenses, like $5,000 in charitable contributions, can be viewed as suspicious by the IRS.
- How to Address It: Encourage clients to provide specific and accurate numbers rather than rounding them off. Accurate figures reflect well-documented income and expenses.
- Failure to Report Foreign Assets or Income
- Red Flag: Foreign income or assets that aren’t properly reported are a major red flag, as the IRS has strict reporting requirements.
- How to Address It: Ensure that all foreign income is reported and that your client complies with reporting requirements like the FBAR (Foreign Bank Account Report) and Form 8938 for foreign assets.
How to Properly Warn Your Clients About Red Flags
As a tax preparer, it’s not only your responsibility to file accurate returns but also to help your clients avoid potential IRS audits by properly warning them about common red flags. Here’s how you can approach this:
- Be Transparent About Potential Consequences: Make sure your clients understand that the IRS may audit returns with red flags. Explain the possible consequences, such as penalties or delays in receiving refunds, if they file returns with inaccurate or exaggerated claims.
- Review the Return Thoroughly: Before filing, go over the return with your client to identify any potential red flags. Take the time to address any questionable deductions, credits, or reported income.
- Encourage Open Communication: Remind clients that they can always reach out if they have questions about deductions or other items on their return. It’s better to discuss potential issues before filing than to deal with them after submission.
- Provide Recordkeeping Guidance: Advise your clients on how to keep proper records, including receipts, invoices, and bank statements. Good recordkeeping can make all the difference if the IRS comes knocking.
- Educate About IRS Audit Triggers: Educate your clients about common IRS audit triggers, such as claiming too many deductions, reporting low income while living an expensive lifestyle, or inconsistent reporting of dependents.
