The Election Laws (Amendments) Bill 2017 is to be sent to the president for assent after the two Houses passed it.
The National Assembly passed the bill on Wednesday and send it to the Senate.
The Senate passed the bill without amendments and returned it to the National Assembly Thursday evening, paving way for presidential assent.
Temporary Speaker Chris Omulele delivered the news of the return of the bill to the National Assembly as members were debating an adjournment motion.
He promised Speaker Justin Muturi will forward it to President Uhuru Kenyatta for assent.
President Kenyatta had earlier this week said he will sign the bill once it is passed by Parliament.
