What to do next
Keep the notice and read its instructions before responding. A general topic page cannot identify the issue in your account.
Read the full account context
Use the whole message or transcript and any IRS notice. A single phrase or code cannot establish every account issue. An ordinary chart gives a planning example; the official tracker provides personalized refund information.
Questions you might have
Does Topic 151 always mean an audit?
The topic concerns appeal rights. The IRS notice supplies the specific decision and response options.
How often should I check?
The IRS normally updates refund information once a day, overnight. One daily check is enough.
When should I contact the IRS?
IRS guidance says to contact them after 21 days from e-filing, six weeks from mailing a return, or when the tracker tells you to call.
Does this site access my tax account?
No. We explain public guidance and calculate date examples. Only the official tracker can show your account status.
