Default partnership rules in Indiana

Indiana follows the original Uniform Partnership Act (UPA), which treats the partnership as an aggregate of its partners rather than a separate entity. The key consequence is that a partner's departure, death, or bankruptcy automatically dissolves the partnership. Profits and losses are shared equally by default. Partners are jointly and severally liable for partnership debts. A written partnership agreement is especially important in Indiana to include continuation clauses.

The most important takeaway: profits are split equally by default in Indiana, regardless of capital contributions. If you and a partner start a business and one of you invests $100,000 while the other invests $5,000, you still split profits 50/50 without a written agreement. This is true in every US state, including Indiana.

LLC defaults in Indiana

Indiana allocates LLC profits and losses in proportion to capital contributions by default. The state does not require an operating agreement. Indiana LLCs must file a biennial business entity report. The state imposes an income tax on business income at a relatively moderate rate.

Indiana defaults to proportional distributions based on capital contributions, which aligns better with many founders' expectations than equal-split states. However, capital contributions alone rarely tell the full story. A founder contributing time and expertise may receive nothing if they didn't invest cash. An operating agreement can account for all types of contributions. Our equity calculator can help you determine a fair arrangement.

What happens when a partner leaves in Indiana

Under Indiana's UPA, any partner's departure automatically dissolves the partnership. The partners must wind up the partnership's affairs, settle debts, and distribute remaining assets. If the remaining partners want to continue, they must form a new partnership. This automatic dissolution can disrupt the business significantly. A well-drafted partnership agreement with continuation clauses is essential.

Important: Because Indiana follows the original UPA, a partner's departure automatically dissolves the partnership. This is a significant risk that can disrupt the business, alarm creditors and clients, and create tax complications. A written partnership agreement with a continuation clause is essential for any Indiana partnership with more than one partner.

Marriage and business equity in Indiana

Indiana is an equitable distribution state that presumes an equal division of marital property as the starting point. Business interests acquired during marriage are generally considered marital property. The court can deviate from the equal split based on factors like the contribution of each spouse and the economic circumstances of each party.

Even though Indiana is not a community property state, marriage can still affect your business equity. In equitable distribution states, courts divide marital property based on what is fair, which may include business interests acquired or grown during the marriage. A clear equity agreement and proper documentation of ownership can help protect your business in the event of a divorce.

Frequently asked questions

Indiana still follows the original Uniform Partnership Act (UPA). This means a partner's departure automatically dissolves the partnership, unlike RUPA states where the partnership continues. Indiana is one of only a handful of states that has not adopted the revised version.

What happens if a partner dies in an Indiana partnership?

Under Indiana's UPA, a partner's death automatically dissolves the partnership. The remaining partners must wind up the partnership's affairs. To avoid this, Indiana partnerships should have written agreements with continuation clauses that allow the remaining partners to buy out the deceased partner's interest and continue the business.

Indiana LLC formation costs $95, and the biennial report fee is $31 (due every two years). These are among the lower costs in the country. Indiana also has a moderate state income tax rate.

What is the default profit split for an Indiana LLC?

Indiana defaults to allocating LLC profits in proportion to capital contributions. An operating agreement can establish any profit-sharing arrangement the members choose.
