A real IRS letter looks official, arriving by mail in a government envelope with the IRS logo, featuring specific details like your SSN/ID, a notice number (CP or LTR), tax year, and legitimate contact info (like IRS.gov/contact), never demanding immediate payment via gift cards or threatening arrest; it explains your taxpayer rights and a clear reason for contact, like account balance or return info.
To tell if an IRS letter is real, check for typos and poor grammar, verify it contains specific personal info (like the last 4 of your SSN), look for an official notice number (CP or LTR) and logo, and ensure it doesn't demand immediate payment via gift cards or threaten arrest, as scammers do. If in doubt, log into your secure IRS Online Account or call an official IRS phone number (not one from the letter) to verify.

All U.S. Treasury checks are printed on watermarked paper. When held up to the light, the watermark reads “U.S. Treasury” from both the front and the back. Any check should be suspected as counterfeit if the check has no watermark, or the watermark is visible without holding the check up to light.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
Revenue agents – examinations (audits)

Scammers send counterfeit checks to individuals, claiming that the recipients are entitled to receive a government grant, tax refund check, or other payments from the Treasury. The check might look legitimate, complete with watermarks and official seals.

What happens if you ignore it: After the deadline passes, the IRS can levy bank accounts, garnish wages, and seize property without further notice. You lose critical appeal rights that would have stopped these actions.

Scammers use phrases that create urgency, fear, or excitement, demanding immediate action like "Act now!" or "Don't hang up," and often involve requests for gift cards or Bitcoin, combined with threats of account compromise or promises of huge rewards (e.g., "You've won!") to bypass logic. Key tactics include isolation ("Don't tell anyone"), emotional manipulation (love bombing, family emergencies), and unusual requests to move money in specific ways (Bitcoin ATMs, secret accounts).
The IRS will never initiate contact demanding immediate payment via gift cards, prepaid debit, or wire transfers; threaten immediate arrest or deportation; or contact you first by email, text, or social media; these tactics, especially involving urgent demands for specific payment types or threats, are key signs of a tax scam, as the IRS always mails a bill first and allows time to appeal.
What taxpayers should do if they receive mail from the IRS
Fact 2: The IRS Will Not Ask Certain Things Over the Phone
The IRS behaves in predicted ways. In fact, the IRS will never call you and… Ask for personal information, like your Social Security number, credit card or bank routing numbers, or other personal information.
A real IRS letter has accurate personal details (name, last 4 SSN digits), professional formatting, a specific notice number, and offers due process; fake letters often have generic greetings, spelling errors, threats (arrest/deportation), demand immediate payment via gift cards/wire transfers, or ask for personal info via links/emails, which the IRS never does, and you can verify real notices by logging into your secure IRS online account or calling official numbers.
A notice may reference changes to a taxpayer's account, taxes owed, a payment request or a specific issue on a tax return. Taking prompt action could minimize additional interest and penalty charges.
The IRS "10k rule" primarily refers to the requirement for businesses and financial institutions to report cash transactions over $10,000 by filing Form 8300 (for businesses) or a Currency Transaction Report (CTR) (for banks), under the Bank Secrecy Act. This rule helps combat money laundering, tax evasion, and terrorist financing, requiring reporting for single transactions or related transactions totaling over $10,000 in cash within a year, with penalties for non-compliance.
The "20k rule" refers to the traditional IRS threshold for reporting income from payment apps and online marketplaces on Form 1099-K: over $20,000 in gross payments AND more than 200 transactions in a calendar year. While a law (the American Rescue Plan) temporarily lowered the threshold to $600, recent legislation, the One Big Beautiful Bill Act (OBBBA) (OBBBA), has reinstated the $20,000/200-transaction rule for tax years starting in 2025, providing relief for casual sellers and gig workers.
