For years, many taxpayers operated under the dangerous assumption that “if the IRS doesn’t send me a form, they don’t know about the money.” In 2026, that era of “honor system” reporting has officially ended. The IRS has fully integrated new third-party reporting networks that track everything from your crypto wallet to your side hustle, and new legislation has fundamentally changed the math on deductions.
This filing season is dangerous because the rules of visibility have changed, but your habits likely haven’t. You might still believe that your digital transactions are private or that the Standard Deduction is always the winner. However, new enforcement mechanisms authorized by the IRS Digital Asset Broker Reporting rules mean the agency now sees data it never saw before. Clinging to old assumptions this year won’t just delay your refund; it could trigger an automated audit letter. Here are the six filing assumptions that will get you in trouble in 2026.
1. “My Crypto Gains Are Private”
For a decade, cryptocurrency traders assumed they could fly under the radar if they didn’t cash out to a bank. That ends with the 2025 tax year. The IRS has rolled out the new Form 1099-DA, which digital asset brokers must now issue for certain transactions.
This form reports your “digital asset proceeds” directly to the IRS, just like a stock brokerage reports your Wall Street trades. If you fail to report a crypto sale that the IRS already has on file via Form 1099-DA, your return will be flagged immediately for a “math error” or underreporting. You can no longer assume your digital wallet is a secret vault; it is now an open book to the Treasury.
2. “No 1099-K Means No Tax Due”
While the federal 1099-K reporting threshold was reverted to $20,000 for the 2025 tax year, assuming you are “safe” from reporting is a critical mistake. Many states—including Massachusetts, Vermont, and Virginia—have kept their own reporting thresholds at just $600.
If you live in one of these states, your side hustle income will be reported to the state, which then shares that data with the IRS. Relying on the federal threshold as permission to hide income is a high-risk strategy in 2026. The IRS is specifically using data matching to identify “lifestyle gaps” where spending exceeds reported income.
3. “My Refund Will Be Reissued Automatically”
In the past, if your direct deposit failed due to a typo, the IRS would automatically print and mail you a paper check. Starting in 2026, new fraud prevention protocols mean the IRS may temporarily freeze refunds rejected by banks. Instead of a check, you might receive a CP53E Notice requiring you to verify your identity and update your bank info online.
If you assume a paper check is “in the mail,” you could be waiting months while your money sits in a frozen status. You must actively respond to the notice to unlock your funds. Passive waiting is no longer a viable strategy for rejected deposits.
4. “The Standard Deduction Is Always Better”
For the last few years, the $10,000 cap on State and Local Tax (SALT) deductions made itemizing pointless for most people. However, the One Big Beautiful Bill passed in 2025 significantly increased the SALT cap to $40,000 for joint filers.
This massive shift means millions of homeowners in high-tax states should now return to itemizing. If you assume the Standard Deduction is still your best bet without running the numbers, you could be overpaying your taxes by thousands of dollars. You need to “run the numbers” both ways every year.
5. “State Refunds Are Irrelevant to Federal”
If you received a state tax refund last year, you might assume it’s free money. However, if you take advantage of the new, higher $40,000 SALT cap this year, that state refund becomes taxable income on your federal return next year.
The IRS receives a copy of your 1099-G from the state. If you leave this “income” off your federal return because you forgot you itemized, the IRS computer automatically catches the mismatch. It is one of the most common reasons for delayed processing.
6. “My Child Tax Credit Is Guaranteed”
Parents often assume the Child Tax Credit (CTC) is automatic if they claimed it last year. However, heightened identity theft protections now require stricter verification of dependent SSNs. If your child’s name on the tax return does not perfectly match the Social Security Administration database, the credit is denied.
This often happens with hyphenated names or misspellings. You cannot assume the IRS will “figure it out” based on prior years. Exact data entry is the only way to bypass the new identity filters.
