It will take the IRS at least a year to catch up with you about the mistake, so it is better to go ahead and Amend your Tax Return to correct the mistake in order to avoid any interest and penalties down the road.
You will need to Amend your Tax Return by filing Form 1040-X. If your Tax Return has already been e-filed and accepted by the IRS, you will need to wait until it has been fully processed and you have either received your refund or your payment has cleared.
Once your Tax Return has been fully processed, you can Amend it to correct the Wage Amount.
