Federal Taxes: Claming Higher Income on W2 Than I Actually Made, Will Pay IRS for Larger Amount

Quick question, Is there any issue with turning in a W2 form that shows a larger income than I was actually paid? I would file /pay all taxes on the larger amount to the IRS. This would be for purposes of a loan.....is there any problem as long as the taxes are paid? Any info would be greatly appreciated.
Thanks
