Consequences of Not Having an ITIN
Cannot file taxes without a TIN. The IRS requires a Taxpayer Identification Number on every tax return. Without an ITIN, you cannot submit your required filings.
Delays in tax processing. Filing without a valid ITIN or with an expired ITIN can result in significant processing delays and additional IRS correspondence.
Potential refund delays. If you are entitled to a tax refund, not having a valid ITIN can delay or prevent you from receiving your refund until the application is processed.
