What Are Capital Contributions - A Guide for New Law Firm Partners

Capital contributions, or buy-ins, are the funds or assets that a business owner or partner invests into a business. For new law firm partners, understanding capital contributions is essential, not just for partnership buy-in, but for long-term financial planning, tax efficiency, and wealth building.

A capital contribution is money or property a partner puts into a business in exchange for ownership equity. In a law firm, this often occurs when you’re promoted to or buy into the partnership.

Why Do Law Firms Require Capital Contributions?

When you're invited to become a partner, the firm may ask for a capital buy-in. This isn't just a fee, it's your stake in the firm. By contributing your capital, you secure your place as a part owner and your investment also helps fund firm operations like payroll or growth initiatives. Sharing in profits and losses ties your financial future to the firm's performance, which further aligns your interests with the firm’s interests.

Many firms allow partners to finance their capital contribution through loans, which brings up important questions about debt, interest, and tax deductibility. Wealthspire can help you understand how all of these moving parts can fit into one cohesive financial plan.

How Much Do Law Firm Partners Typically Contribute?

The amount that law firm partners typically contribute varies widely between firms but generally falls somewhere between $250,000 and $1M depending on the firm's size and structure, whether you're a junior partner or equity partner, and the regional markets.

How Are Capital Contributions Taxed?

Capital contributions aren’t considered taxable income for the firm, and they’re also not considered compensation, so they can’t be deducted on your personal income tax return. Capital contributions do however impact your basis in the partnership which impacts how much of the firm’s losses you can deduct and the tax liability you have when you leave or sell your partnership interest. This is where a financial planner experienced with law firm structures becomes invaluable.

Should You Finance a Capital Contribution?

Whether your firm offers an internal loan, or you're considering a bank loan, there are many factors to consider. You’ll want to look into the loan terms and take into consideration the interest rate and the payback period. Taking out a loan will also impact your cash flow, which impacts your opportunity cost, or what else you could do with the money. There are many tax implications of taking out a loan, so you’ll need to consider a strategy that won’t compromise your financial goals like retirement savings or buying a home.

Capital Contribution vs. Capital Account

The capital contribution is what you invest whereas the capital account is your running balance in the partnership including contributions, earnings, distributions, and allocated losses. Keeping track of your capital account is crucial for exit planning and tax planning.
