A capital contribution to an LLC is what a member puts into the company in exchange for a share of it: cash, property at a value the members agree, or services valued the same way. The operating agreement records each contribution in a schedule, and the share it buys is arithmetic on that schedule, each member's contribution over the total. This page walks how an LLC capital contribution is recorded, works the shares from an example, and points at the free worksheet on this site that does the same from your figures. It publishes no tax treatment and no rule about what a state requires the schedule to say; the set-aside for tax on the single-member worksheet is the owner's own figure.
Recording the contribution: what, when and at what value
The schedule records the member, the date, what was contributed and its agreed value. Cash is its own value; property and services are whatever the members agree, and the agreement records that agreement. The worksheet takes the values as entered and works nothing about whether a valuation is fair; that is the members' decision and, where it matters for tax, their accountant's. What it works is the total and each member's share of it, on the page, from the schedule.
The share a capital contribution llc buys, from the total
On the worked example, $50,000, $30,000 and $20,000 make a total of $100,000 and shares of 50%, 30% and 20%. Members can agree a different split from their contributions, and many do; if they do, the agreement records the agreed shares and the contribution schedule separately, and the worksheet still shows what the contributions alone would imply so the difference is a decision the members have seen rather than an accident.
Later contributions and the re-cut they cause
A second contribution changes every share, not just the contributor's. A member adding $20,000 to the example company raises the total to $120,000 and moves their share from 50% to 58.3% while the others fall. The amendment worksheet on this site works exactly that re-cut when capital comes in at a valuation, showing the new share and everyone's dilution, so a capital call or a buy-in is recorded with numbers the members have agreed.
Capital accounts: where the contribution goes next
Each contribution opens a capital account for the member, which rises with profit left in the company and falls with distributions and draws. For a single member the capital account is the whole arithmetic of the agreement, and the single-member worksheet carries it through a year of draws and a tax set-aside the owner chooses. LLC Lane Pro keeps every member's contributions and shares against the company; the free worksheets work one schedule at a time with no account.
Questions people ask about capital contribution to llc
How is ownership percentage calculated from a capital contribution?
Each member's contribution over the total of all contributions: $50,000 of $100,000 is 50%. The worksheet works it for up to three members from the figures you enter; the members can agree a different split and record it.
Does a capital contribution to an LLC have to be cash?
The agreement can record cash, property at an agreed value or services valued the same way; what counts and how it is valued is the members' agreement and, for tax, their accountant's question. The worksheet takes the values as entered.
What happens to the shares when a member contributes more later?
Every share moves. The amendment worksheet works the new share and everyone's dilution when capital comes in at a valuation, from the figures you enter.
