Can I File My Extended Return With A Different Company?

Did you file a tax extension with another tax provider but now want to finish filing your tax return with TaxAct®? Good news — you’re not locked in! TaxAct makes it easy to switch, so you can confidently tackle your income tax return and (more importantly) avoid any last-minute tax deadline stress.

Let’s clear up the confusion about switching providers after filing a tax extension, walk through what you need to do, and help you cross the filing finish line before this year’s Oct. 15 due date.

Can I file my tax return with a different company than the one I used to file my extension?

Yes! If you used a different company (or even irs.gov) to submit your application for automatic extension of time to file, you can absolutely still use TaxAct to e-file your final federal tax return or business tax return. You aren’t required to finish your tax filing with the same provider that filed your federal extension form.

Whether you filed Form 4868 (for individuals) or Form 7004 (for businesses), the Internal Revenue Service (IRS) doesn’t require you to use the same software for both your extension and your final return. The only thing that matters is that you submit your completed tax forms and any tax payment owed before the filing deadline. This year, that’s Oct. 15, 2025.

Will the new provider know I filed an extension?

Not automatically, but that’s okay. The IRS keeps track of all filing extensions tied to your tax identification number (like your SSN or EIN), so the agency will know you’ve requested an extension.

When you file taxes with TaxAct, we will prompt you to provide us with the amount of estimated tax you may have paid when submitting your extension request (found on your Form 4868). This way, you’ll get a credit for the amount you already paid.

When are taxes due with extensions?

For most filers, the due date of the return after requesting a federal extension is Oct. 15. If Oct. 15 falls on a weekend or holiday, the next business day becomes the filing deadline.

If your area was affected by a natural disaster, you might have a different extended filing deadline. Check out our list of extended tax deadlines due to natural disasters.

What do you need to file your return with TaxAct?

Completing the filing process with us is easy, but you’ll want to have these on hand just in case:

A copy of your extension form (Form 4868)
Any confirmation from your previous provider or irs.gov acknowledging your extension request
Records of any tax payment made with your extension of time (also found on Form 4868)
All your usual tax documents for the tax year (like W-2s, 1099s, receipts, etc.)
Your taxpayer identification number (SSN or ITIN)

Try using our tax preparation checklist to make sure you have everything you need. If you’re a small business or self-employed, remember to gather all your business income tax records too.

How to finish your tax return in TaxAct after filing an extension elsewhere

Ready to wrap up your taxes? Here’s what you need to do:

Sign in or create a TaxAct account.
Start a new tax return for the current tax year and proceed through the Q&A process.
To indicate you previously filed an extension request, you will need to enter the amount of tax you paid when you requested an extension. You can easily review this by clicking Federal, then selecting Credits, followed by Amount paid with extension, as shown below.

You can then enter the amount you have already paid, as shown below. This will ensure you get a tax credit for that amount. (If you didn’t pay anything when you requested an extension, just enter 0).

Continue with the interview process to complete your income tax return as usual.
Review your return, pay any remaining tax liability, or set up a payment plan for unpaid tax if needed.
E-file your return or print and mail a paper form (but e-filing is faster!).
Keep a copy of your filed return and confirmation for your records.

FAQs

Is there a way to import my tax extension data into the new tax software?

Most tax software — TaxAct included — won’t automatically pull in your tax extension data from another company. Instead, all you need to do is manually enter the estimated tax that you paid when you initially made the extension request (see the instructions in the previous section). It’s a good idea to keep all your extension paperwork handy so that you can take care of this part quickly.

How do I prove to the new provider that I already filed a tax extension?

All you need to do is enter the amount of tax you paid when you requested your extension. The IRS already knows you asked for an extension, so you just need to tell TaxAct’s software how much you should be credited for. That’s it!

What forms do I need to give the new tax preparer if I filed an extension elsewhere?

Make sure you have Form 4868 on hand when filing with TaxAct — this form shows how much tax you already paid, which our software will ask you about. Other than that, just have your normal tax documents ready.

Will switching providers delay my refund?

Nope, switching won’t delay your tax refund as long as your return is accurate and the IRS accepts it! However, if your return is not accurate, you will need to file an amended return, which could delay your refund.

What is the deadline for filing income tax returns that have received extensions?

The filing deadline for individual income tax returns that received a valid extension is Oct. 15, 2025, for most individual taxpayers (unless a different deadline applies due to special situations). The original due date is typically April 15, meaning an extension gives you an additional six months to file.

Can I file another tax extension after Oct. 15?

No, the IRS doesn’t allow you to request a second extension for the same tax year. Oct. 15 is typically the last day to file your extended income tax return unless you qualify for special relief due to disaster situations or are living abroad.

What happens if I miss the Oct. 15 deadline after filing an extension?

If you miss the deadline, you may face a late filing penalty and late payment penalties, so it’s best to try to file as soon as possible.

How do I track my refund after filing an extended return?

After you’ve e-filed, you can check your federal tax refund status at irs.gov using the “Where’s My Refund?” tool or the IRS2Go mobile app.
