Bought a Mazda CX-50 in 2025, is it too late to deduct the interest paid if I already filed?

[nsoper9]

Is there a way to amend my filing?

You cannot change or add anything on the return that you just e-filed, nor can you stop it.  It is too late, just like when you put an envelope in a US mailbox on the corner.  The IRS does not allow you to take it back.

If you left out a W-2, a 1099G, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.”  The changes will go nowhere.

Now you have to wait until the IRS either rejects or accepts your return.  If your return is rejected, you will be able to go into your account and make the necessary changes to your tax return and re-submit your return. 

 If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund.  THEN you can prepare an amended tax return and e-file or mail  it in. You have to be able to work from that return exactly the way it was when it was e-filed originally.  You will need to use a form called a 1040X.

  Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself.  Sit tight and wait until you see what the IRS does with the return you just e-filed

The Form 1040X you need becomes available in late February,  But wait until your return has been processed.

Once a tax return has been filed it cannot be changed, canceled or retrieved

You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

No it is not too late to deduct the interest, but it is too early to amend your return.  The amended forms do not come out until mid February to early March.

In order to claim this interest the following criteria must be met:

• The car was purchased not leased
• Final assembly occurred in the US
• It is NOT a business use, but was purchased for personal use
• It has a GVWR of less than 14,000lbs (car, truck, SUV, mini van or motorcycle)
• Loan was originated in 2025 and must be secured by a lien on the vehicle or the title
• Your income must be less than $100,000 if single or $200,000 if married filing jointly to receive the full deduction. 
•  If your income is over $150,000 if single or $250,000 if Married filing jointly, you are not eligible

Note:  The interest deduction is capped at $10,000.  This is an above the line deduction, not a credit meaning it will lower your AGI and taxable income.  It will not be an amount that is refunded to you, but it could result in a refund by lowering your taxable income.  If you already received a refund of all of the money you had withheld, then you may not see a difference in your return.

When the amended forms are ready, you will just need to log in, select Amend my return and then take the steps below. 

You can enter your car loan interest by selecting the following:

1. Deductions and credits
2. Cars and Other things you own
3. Start next to Car Loan Interest
