I want to file a new tax claim

Did you already file and need to change it?  Or do a new original return?  What year?

Sorry, Online is closed now so you can not start a new 2018 return or finish one. Oct 15, 2019 was the last day to efile.  2018 is now the prior year. You can only buy the download for prior years. You have to buy a separate program for each year. They only sell the last 3 years. You need a full Windows or Mac computer to install it on. Buy the download here

You have to print and mail prior year returns. When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return. Don’t forget state.

Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.

If you are getting a refund, there is not a penalty for filing past the deadline. You have 3 years to file for a refund. If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.

There is no such thing as a Tax Claim.

You file a Tax Return to report your income, deductions and credits.  The federal tax return is sent to the IRS.  If your total tax payments were greater than your total tax liabilities then you will receive a Tax Refund for the overpayment.

If you have filed a 2018 tax return and it has been accepted by the IRS, you Cannot file another 2018 tax return.  To make any changes to the tax return that was filed you must amend the tax return.  You do not amend a tax return until you receive any tax refund or have paid the taxes owed.
