As a professional tax preparer for a major national service, one of my jobs is to recognize when a filer may be giving me fraudulent information. Although it’s not possible to catch all the bogus information, there is a list of common dodges that dishonest filers attempt to pull to reduce or avoid their tax bill.
False Deductions
One of the most obvious ways that some filers attempt to deceive the Internal Revenue Service (IRS) is when they try to claim additional deductions. When they see their tax bill or refund amount after we have finished the initial interview, they will have me put their return on hold because they suddenly remembered some “additional expenses” that they forgot to include before. Then they return with a list of these items (without any receipts or supporting documentation) and ask me to enter them into the return.
Knowingly filing a false tax return on someone else’s behalf will cause the IRS to discipline both the customer and the tax filer.
Claiming Dependents Who Don’t Qualify
A sure-fire way to lower any tax bill is to claim a dependent or two, since it can give the filer “Head of Household” status. With dependents, taxpayers are also able to add exemptions and tax credits for dependents under age 17. This can be a major point of contention for divorced couples, especially those who share custody of one or more children.
For many in this situation, it becomes a race each year to see who can file first and “win” by claiming the kids. Of course, when one spouse claims one or more dependents unjustly, the other spouse can notify the IRS of the violation and have the undeserved refund disallowed. However, this process can take months and can be a headache for the ex-spouse who should have claimed the children.
The IRS tightened up the rules for filers who claim kids for the earned income credit by requiring them to maintain proof, starting in 2014, that shows that each dependent claimed met the proper support and residency tests.
Another dodge is to claim parents who do not live with the taxpayer by showing false statements of financial support.
Divorce-Related Fraud
Although child support is nondeductible for payers, some filers formerly tried to claim this expense as spousal support or alimony, in hopes that the IRS wouldn’t notice the discrepancy and would allow the deduction. If they couldn’t produce a divorce decree showing that the payment was alimony, then they shouldn’t have deducted it on any return.
Important
In 2019, the Tax Cuts and Jobs Act changed the way spousal support and alimony are treated for tax purposes. Under the new rule, spousal support and alimony payments are only deductible if paid under a divorce or separation agreement executed before 2019. If the divorce or separation was executed in 2019 or later, the payments are not tax-deductible. If the divorce or separation agreement was executed before Dec. 31, 2018, but a qualifying modification was made after that date, the payments are not tax-deductible.
Income Fraud
Filers who fail to report income can not only lower their tax bill but also, in certain situations, collect unemployment benefits. Those who report abnormally low income for the year will generally trigger a red flag, especially if they are claiming dependents. In some cases, they may be receiving child support or state and/or federal assistance that is nontaxable, but many of these filers also worked jobs for which they were paid in cash. This type of income is especially tempting to omit if it could otherwise be counted as self-employment income, because it would be subject to regular income tax along with payroll taxes for Social Security and Medicare.
Personal vs. Business Expenses
Breaking down business versus personal use for expenses such as vehicles and office equipment can be a gray area for some customers. Customers who increase these amounts or percentages towards business use several times tend to arouse my suspicion unless they can cite specific additional instances of use.
More creative cheaters might create a dummy business entity to which false expenses are attributed.
Overseas Investors
Some clients think that investment or other income earned in other countries can be left off their tax return. This is not the case if they are U.S. citizens.
If a customer tells me about how they resided in another country for any material period, but have no reported income from that location, that information should be closely questioned and thoroughly documented.
If the IRS Catches You
Of course, the rules clearly state that if a tax preparer knowingly submits fraudulent information on a tax return prepared for a client, then both the client and the filer will be subject to disciplinary action or even criminal penalties (if the IRS discovers it). The client will also be subject to interest and penalties on the amount of tax that should have been paid.
Customers should be informed that adding substantial deductions to their return may increase the chance that they will be selected for an audit. If an audit happens, the IRS will disallow any deduction or other incentives for which there is no proof, even if it was a legitimate expenditure that was actually paid.
The IRS may then decide to audit other years of the client’s returns to see if they cheated on those, too.
If you plan on filing fraudulent returns, you should know that whistleblowers can report tax cheats to the IRS, which will pay a reward of up to 30% of the additional tax, penalties, and other amounts that it collects.
The Bottom Line
Taxpayers who try to cheat on their taxes are asking for trouble. If caught, the consequences they face usually far outweigh what they’re attempting to gain.
