Hi, I will be self-employed until July 1st this year. Which means I will earn untaxed income for the first half of year. Should I still pay equal quarterly amounts?

For example, say I owe $10k in total taxes from this self-employment income, should I pay $2.5k/quarter or $5k for Q1/Q2 - as the income is all earned in the first two quarters. After July 1st I will be employed and receiving income that is taxed.
