Failure to disclose cash payments and tax fraud

On Behalf of | Jun 18, 2026 | Fraud |

Anyone in New York engaged in a trade or business must disclose cash payments above $10,000 to the Internal Revenue Service (IRS) and the New York State Department of Taxation and Finance. This is when one receives more than $10,000 in a single transaction or related transactions

For example, when an auto dealership receives $15,000 in cash for a used car. Or when a travel agent receives $8,000 in cash from a client on a trip on Monday evening, and the same client adds $4,000 on Tuesday morning so the travel agent can add hotel reservations. These two are related transactions totaling $12,000.

A cash payment above $10,000 is reported using the IRS Form 8300 within 15 days after the transaction. Failing to disclose cash payments can be considered tax evasion or underreporting income. If caught, you might face penalties and other severe penalties. 

What if it’s an honest mistake?

Failing to disclose cash to the IRS can be an honest mistake. It’s not uncommon for taxpayers to misunderstand the law, fail to recognize that certain transactions should be treated as related or fail to know that a certain substantial cash gift should be reported. 

Moreover, record-keeping errors can lead to someone not disclosing cash payments to the IRS. For instance, when receipts are misplaced, a math error occurs or physical ledgers are mishandled. 

Additionally, someone may not consider casual earnings, such as from selling personal items, as reportable income. Individuals who mix personal and business funds, especially small business owners and freelancers, are also more likely to overlook cash deposits.

The IRS uses specific patterns to determine if someone willfully evaded taxes by not reporting cash payments. If your behavior is interpreted as fraudulent intent, you may get into trouble. Consider legal guidance to protect yourself from a tax fraud conviction.
