File all tax returns that are due, regardless of whether or not you can pay in full. File your past due return the same way and to the same location where you would file an on-time return.
If you have received a notice, make sure to send your past due return to the location indicated on the notice you received.
Why you should file your past due return now
Avoid interest and penalties
File your past due return and pay now to limit interest charges and late payment penalties.
Claim a refund
You risk losing your refund if you don’t file your return. If you are due a refund for withholding or estimated taxes, you must file your return to claim it within 3 years of the return due date. The same rule applies to a right to claim tax credits such as the Earned Income Credit.
We hold income tax refunds in cases where our records show that one or more income tax returns are past due. We hold them until we get the past due return or receive an acceptable reason for not filing a past due return.
Protect Social Security benefits
If you are self-employed and do not file your federal income tax return, any self-employment income you earned will not be reported to the Social Security Administration and you will not receive credits toward Social Security retirement or disability benefits.
Avoid issues obtaining loans
Loan approvals may be delayed if you don’t file your return. Copies of filed tax returns must be submitted to financial institutions, mortgage lenders/brokers, etc., whenever you want to buy or refinance a home, get a loan for a business, or apply for federal aid for higher education.
If you owe more than you can pay
If you cannot pay what you owe, you can request an additional 60-120 days to pay your account in full through the Online Payment Agreement application or by calling 800-829-1040; no user fee will be charged. If you need more time to pay, you can request an installment agreement or you may qualify for an offer in compromise.
What if you don’t file voluntarily
Substitute Return
If you fail to file, we may file a substitute return for you. This return might not give you credit for deductions and exemptions you may be entitled to receive. We will send you a Notice of Deficiency CP3219N (90-day letter) proposing a tax assessment. You will have 90 days to file your past due tax return or file a petition in Tax Court. If you do neither, we will proceed with our proposed assessment. If you have received notice CP3219N you can not request an extension to file.
If any of the income listed is incorrect, you may do the following:
- Contact us at 1-866-681-4271 to let us know.
- Contact the payer (source) of the income to request a corrected Form W-2 or 1099.
- Attach the corrected forms when you send us your completed tax returns.
If the IRS files a substitute return, it is still in your best interest to file your own tax return to take advantage of any exemptions, credits and deductions you are entitled to receive. The IRS will generally adjust your account to reflect the correct figures.
Collection and enforcement actions
The return we prepare for you (our proposed assessment) will lead to a tax bill, which, if unpaid, will trigger the collection process. This can include such actions as a levy on your wages or bank account or the filing of a notice of federal tax lien.
If you repeatedly do not file, you could be subject to additional enforcement measures, such as additional penalties and/or criminal prosecution.
