My wife and I are trying to buy our first home and sold an index mutual fund with about 60k in capital gains.
This is my first time reading form 1040-ES, but it seems that it is made for an individual without withholding rather than an individual with withholding and one or more windfall gains.
Do we need to pay the entirety of the capital gains tax (about 9k) before June 15th? Or could I use losses later in the year to entirely offset this gain? If the market drops appreciably, then I could offset all/some of this gain. Is there software that can make this process easier?
I found this question on this topic, but it addresses more the existence of estimated taxes rather than the timing.
FWIW, neither of our income is large enough to handle this tax bill with a W-4 adjustment. We will both be unemployed in about one month and I'll be starting a new job in the fall, although our total income this year will be about the same relative to last year (ignoring the capital gains). We file jointly.
