Victims of winter storms that began February 11, 2021 now have until June 15, 2021, to file various individual and business tax returns and make tax payments.
You can still use TurboTax to prepare and file your return if you are a Texas resident. The program may not have been updated yet for the extended deadline, but it will be. You can go ahead and prepare your return, and you can file. If you want to arrange for your tax payment to be drafted from your bank account, you won't be able to set up a payment date later than April 15 at this time. You can still mail a check, or pay electronically by going to https://www.irs.gov/payments.
If you are receiving a refund there is no impact.
