After filing your original return, you may determine that you made an error or omitted something from your return. Although the IRS often finds and corrects errors during processing, there are certain situations in which you may need to file an amended return to correct an error or make other changes to your return.
On Form 1040-X, enter your income, deductions, and credits from your return as originally filed or as previously adjusted by either you or the IRS, the changes you are making, and the corrected amounts. Then, figure the tax on the corrected amount of taxable income and the amount you owe or your refund.
Any interest and penalties still apply. If you amend and end up owing more than you did originally, you could be subject to interest and penalties. The worst part about such interest and penalties is that they apply to the difference owed on the amended tax return starting from the date of your original return filing.
Here's what you need to do: Resident or Non-resident? Use Form 540 (resident) or Form 540NR (non-resident) along with Schedule X to explain the changes. Prepare Online, Mail Later: Though eFile helps create your amended return, it can't submit it electronically.
