Unfiled Tax Returns
If you missed a filing deadline, filing may still be required even if you cannot pay the balance. Leaving required returns unfiled can delay resolution options, cause refunds to expire, and lead the IRS to file a substitute return that may not include deductions or credits. The steps and deadlines depend on your filing history and circumstances.

What to do first
Identify each tax year that may be missing and confirm what the IRS has on record. Gather income forms, business records, prior returns, and notices. If documents are missing, request replacements or review available IRS transcripts. Do not assume an IRS estimate includes all of your income, expenses, or deductions.

What may happen when you do not file
The IRS may send notices, assess tax based on information available to it, delay refunds, or begin collection after an assessment. Failure-to-file penalties may apply when tax is due. The outcome depends on the year, whether tax was owed, and any applicable exceptions or relief.

Build a filing plan
Work year by year, prepare accurate returns, and follow any address or response instructions in IRS notices. Filing does not automatically resolve an unpaid balance, so consider payment or collection options after the returns are current. If you are unsure which years are required, review IRS records and get qualified help.
