Uber will not withhold tax for you. If you are a rideshare driver you are an independent contractor. They do not withhold tax, Social Security or Medicare from your earnings. So you have to pay self-employment tax when you file a tax return, or you can send in quarterly estimated payments to prevent a big tax due amount at tax time.
Another approach would be to have more withheld from your W-2 pay if you have another job from which you will receive a W-2. Increase the amount that employer is withholding from your paychecks by filling out a new W-4 for the employer.
