I see from the IRS website that the deadline for making solo 401(k) contributions is my filing deadline (that is April 15), but it is unclear to me whether I can file earlier (say February) but then wait to April to make my 401(k) contributions.
I have an unusually large refund coming my way this year and would like to use to partially fund the 401(k) contributions.
Any thoughts? Reference to an IRS document would be appreciated.
Thanks.
