<prompt> Human: I just received a CP2000 notice saying I owe more money than the amount of income I forgot to report.I drove for lyft one time to get their new driver bonus and forgot to report it. I made 1000 in income but now it says I owe 1,246 in taxes. This doesnt seem right to me that I owe more in taxes than the money I made. What can I do?Edit: I appreciate all of the advice and input from everyone. As many recommended, Im going to speak with a CPA. Ill post an update once I speak with them. Wish me luck!  <response>: Sometimes, if the IRS believes you earned income from a source you didnt report, they will apply an averageestimated amount of income to you then recalculate your tax lability based on your updatedestimated income. Filing an amended return with a copy of your 1099, or proof of total earnings from that source, should clear it up. You will likely have taxes, penalties, and interest due. Many credits are calculated off your AGI, and will be impacted as well. It wont be more than your income. Interest does compound though so the faster you handle it, the better.
