Tax client is on an approved extension

Tax client owns an which provided the 2025 W-2 Post April 15th the LLC owner has determined hat the W-2 salary is incorrect and understated by $8,75.0.00 . Clint need to file a Federal Form W-2c ASAP. This will increase his payroll taxes. The LLC can make the required tax deposits electronically.

I plan to attach the soft copy with the 1040 I doubt that the SSA and will have updated their files by 10/15/26.

Should the tax client file the 1040 electronically in October (allows time to process the W-2c) ?

Should the client paper-file or e-file?

Have I missed anything?

Note: This situation arose after terminating the payroll processing firm.

did the withholding change? I dont think IRS will care if you report more income than they can see, it would just be any additional withholding that may delay any refunds.

Lisa,

Thank you for your response.

The first W-2 was filed in a timely manner in January. The client requested a six-month extension of the time to file the Form 1040. During this time the client identified the error in the January W-2. He needs to file a corrected W-2 before he files the Form 1040. The Income will increase as will the Social Security and Medicare taxes.

In my opinion, when the Form 1040 is e-filed the IRS will have new, revised W-2 information that does not agree with the January 2026 W-2 data.

Cheers!

Once you have the corrected W-2, I would just file the return. I wouldn’t worry about waiting to make sure the W-2C is processed.

Slava Ukraini!
