Symptoms / When you see this

✓ “Refund still processing”, “refund delayed”, or pending status for longer than expected.
✓ Transcript shows hold/freezes or notice issuance codes.
✓ You receive a verification/review letter and refund timing changes.

Root causes (grouped)

✓ Normal processing and mismatch review (income/withholding/credits).
✓ Identity verification or fraud screening letters.
✓ Refund offsets for eligible debts or balance due adjustments.
✓ Account holds/freezes pending additional action.

Step-by-step fixes (safe, prioritized)

✓ Confirm the tax year, filing status, and the newest transcript entries first.
✓ If a notice/letter exists, follow its instructions and deadlines exactly.
✓ If identity verification is required, complete it using official IRS methods only.
✓ If an offset is indicated, reconcile the offset source; do not refile to “force” a refund.
✓ Avoid resubmitting the same return unless the IRS instructs it; duplicates create delays.

What NOT to do

✓ Do not file duplicate returns “just in case”.
✓ Do not follow third-party links or phone numbers to “verify” identity.
✓ Do not send unsolicited documents unless requested by a notice/letter.

If it persists (escalation checklist)

✓ Collect: notice copies, transcript snapshots, return copy, W-2/1099 data, and dates.
✓ Document every submission with proof of delivery/submission confirmation.
✓ Use official IRS support paths when the timeline exceeds typical ranges for your situation.

FAQ

Does code 846 mean my refund is guaranteed?

It indicates issuance at the transcript level, but timing and delivery method can still vary. Check dates and any later offsets/adjustments.

Should I file again if nothing changes?

Usually no. Duplicate filings can slow resolution. Follow official instructions or respond to the notice.

What is the fastest way to know what the IRS needs?

A specific notice/letter. If one exists, its instructions and deadline take priority.

Can offsets reduce refunds?

Yes. Refunds can be offset for certain debts. Transcript entries and notices often indicate offsets.

If I verified identity, how long until updates show?

It varies. Monitor your account/transcript for new entries; avoid duplicate verification attempts unless instructed.

What should I keep for records?

Notices, proof of verification/submission, transcript snapshots, and supporting filing documents.

Are online “refund trackers” enough?

They can be useful, but transcript entries and notices provide more precise signals when delays occur.

When should I escalate?

When a deadline is close, when final notice letters are involved, or when delays exceed normal ranges for your scenario.
