When you file your federal tax return, the IRS reviews millions of returns and sometimes needs to follow up for clarification, correction, or verification. IRS Letter 1058 is one such notice sent to taxpayers when the IRS identifies discrepancies or needs additional information to finalize the processing of a tax return or refund.
Purpose and Context of IRS Letter 1058
The IRS issues various letters and notices to communicate with taxpayers. Letter 1058 specifically signals that while your tax return has been processed, the IRS has found a mismatch, potential error, or needs further documentation. This letter could indicate changes to your refund amount or ask you to confirm or provide additional information.
Unlike audit notices, Letter 1058 is a routine correspondence designed to resolve issues quickly and avoid delays or incorrect refunds. It might involve matters such as mismatched income reported by employers, incorrectly claimed dependents, or mathematical errors identified after filing.
What to Expect When You Receive Letter 1058
Typically, Letter 1058 includes:
- A clear explanation of the issue or adjustment made
- The updated refund or tax balance, if applicable
- Instructions for your response, including what documents to provide
- A deadline to respond, usually within 30 days
For example, if you filed a tax return expecting a refund based on your reported income, and the IRS received different income data from your employer, Letter 1058 will notify you of this change and may ask for proof to dispute or confirm their adjustment.
Who Might Receive Letter 1058?
Any taxpayer whose tax return raises questions during processing can receive this letter. Common triggers include:
- Income discrepancies between your return and IRS records
- Dependents claimed incorrectly or requiring verification
- Calculation or math errors on your tax return
Receiving Letter 1058 does not necessarily mean you owe money; rather, it’s the IRS’s way to ensure accuracy before finalizing your refund or tax balance.
How to Respond to IRS Letter 1058
Responding correctly and timely to Letter 1058 is vital to avoid refund delays, penalties, or interest. Here are key steps:
- Carefully read the letter. Understand exactly what the IRS is asking.
- Compare details. Check your tax return and all related documents against the IRS’s points.
