After you file, the Internal Revenue Service processes your return, checks it for errors and compares its information with records it receives. If the return is accepted, the IRS determines whether you owe tax or are due a refund; it may also follow up if something needs correction or review.
Filing is the start of a process, not always the final word on your tax bill. Knowing what the IRS does after you file can help you understand delays, respond to a notice and keep track of what happens next.
| IRS action | What it involves | What the taxpayer should do |
|---|---|---|
| Routine processing | Recording and processing a federal return | Keep a copy of the filed return |
| Information check | Comparing reported figures with documents such as Forms W-2 and 1099 | Check the return against tax documents |
| Correction or notice | Addressing an error, mismatch or request for clarification | Follow the notice instructions and deadline |
| Audit | Closer examination of selected items and supporting records | Provide relevant records and respond to the IRS |
- 2 forms: W-2 and 1099 Examples of third-party income documents that may be compared with a return
- 1 federal agency: the IRS Agency that administers federal tax laws and processes federal returns
- 0 guarantee A refund does not guarantee that every reported item has been fully verified
What does the IRS do when it receives a federal return?
The Internal Revenue Service (IRS) administers federal tax laws and processes federal individual income tax returns. After receiving a return, it checks whether the filing can be processed and whether basic identifying details and return information are present.
Processing is not an audit
For a return that can be processed, the IRS uses the information reported to calculate whether the taxpayer paid more tax than was due or still owes a balance. These are distinct outcomes: a return may show an overpayment or an amount due, based on the figures on that return.
Acceptance for processing does not mean that the IRS has fully verified every reported item. It indicates that the return passed the initial processing checks; it is not, by itself, confirmation that all entries have been examined or approved.
How does the IRS check return information?
The Internal Revenue Service checks return information by comparing the income a taxpayer reports with documents filed by employers and other payers, including Forms W-2 and 1099. This is an information match, not automatically an audit.
A mismatch between a return and a third-party document can lead the IRS to seek a correction or review the discrepancy further. Before filing, taxpayers should compare their return with the tax documents they received, including any corrected W-2 or 1099 that replaces an earlier version.
Information check versus audit
A routine check compares reported figures with information supplied by third parties; an audit examines a tax return more closely. Forms W-2 and 1099 are concrete records to verify against the return, while an audit is a separate, more detailed review.
When does the IRS issue a refund?
Refund status and return review
The IRS issues a refund after processing a tax return when the tax payments and refundable credits claimed exceed the tax owed on that return. The amount due is calculated from those entries; receiving a refund does not mean the IRS has confirmed that every entry is correct.
IRS processing can take longer if the return contains an error or needs additional review. The agency issues the refund after that processing step, so a delay in the refund may reflect a delay in reviewing the return rather than a change to the amount claimed.
The IRS’s Where’s My Refund? tool is the agency’s named option for checking refund status. It provides a way to check progress, but a refund amount by itself is not a finding that all information on the return has been verified.
What happens when a return has an error or a mismatch?
A missing or incorrect figure can prompt the Internal Revenue Service (IRS) to adjust a return or ask the taxpayer to clarify the discrepancy; a notice about a proposed adjustment is not, by itself, an audit or a final determination of additional tax.
An IRS notice explains what issue the agency identified and what the taxpayer should do next. Read the notice carefully and follow its response instructions and the deadline printed on it; the required action depends on the notice, so do not assume that every notice calls for the same response.
Keep the records needed to respond
Keep a copy of the filed return, records supporting its figures, and all IRS correspondence together. If the IRS asks about a figure, those documents can help the taxpayer check the return, understand the question, and prepare a response that follows the notice’s instructions.
How is an audit different from routine processing?
Review is not the same as enforcement.
Routine IRS processing records a filed return and checks it for processing issues; an audit is a closer examination of selected tax items and the records supporting them. The distinction is between handling the return as filed and asking the taxpayer to substantiate particular entries—not between a routine check and an automatic bill.
An IRS audit may ask for records supporting income, deductions or credits claimed on the return. The review can be handled through correspondence or another process, depending on the case; the method does not change the central question of whether the selected items are supported.
- Routine processing: the IRS checks and records the return.
- Audit: the IRS examines selected items and may request supporting records for reported income, deductions or credits.
- After review: the IRS communicates its findings, and the taxpayer can respond.
An audit alone does not establish that additional tax is due. The IRS’s findings come after its review, and the taxpayer has an opportunity to address them; therefore, the fact that a return is examined should not be mistaken for a final determination of liability.
When can filing information or a refund be delayed?
An IRS return may take longer to process when it contains an error, leaves out information or requires additional review, and a refund can be delayed while the issue is resolved. A mismatch between income on the return and a Form W-2 or Form 1099 may lead the IRS to ask a question or adjust the return.
Common limits and mistakes
Filing a return—or receiving its refund—does not rule out a later IRS inquiry. A refund is not a guarantee that every item on the return has been accepted as final, so taxpayers should keep relevant records and respond if the IRS contacts them.
- Return error or missing information: The IRS may need more time to process the return.
- Income mismatch: A difference between reported income and a Form W-2 or Form 1099 can prompt a question or adjustment.
- IRS notice: Follow the notice’s specific instructions to determine what to do; do not rely on a general assumption about filing or refund status.
Federal law gives the IRS authority to assess and collect tax. If a notice arrives, its stated request and instructions—not the fact that a return was filed or a refund received—govern the taxpayer’s next step.
