The OASDI tax rate is 6.2 percent, so an employee with wages up to or above the maximum in 2019 would pay $8,239.80 in tax and the employer would pay an equal amount. Self-employed individuals pay tax at a 12.4 percent rate up to the limit. The 2018 wage base is $128,400, for a $7,960.80 maximum amount of OASDI tax. Click here (PDF) for more information.
