A bucking bull partnership is two or more people who each own a percentage of the same bull and split its bills and its earnings by agreement. There’s no standard deal. Every partnership is whatever you and your partners agree to, and that’s exactly where they can go sideways.
Here’s the pattern with these deals: the trouble almost never starts with the bull. It starts with the stuff nobody wrote down. Every bull partnership comes down to four questions. Who owns what? Who pays for what? Who gets paid? And how does everybody know? Answer those up front, in writing, and partnerships stay friendly. Leave them fuzzy and somebody ends up doing math in the truck at 10 p.m.
What you’re buying when you buy into a bull
When you buy into a bull, you’re buying a percentage of him. The math on the purchase is simple. As stock contractor Travis Eckroth explained in Bucking Stock Talk’s guide to bull partnerships, if a bull costs $10,000 and you take 20 percent, your share is $2,000.
What that share gets you depends on the deal. Some partners want a name on a bull and a reason to watch the scores. Others want to help feed, haul and be part of the whole program. Some partnerships cover a single competition bull. Others cover breeding cows, embryos or a whole crop of calves. None of these is wrong. They just need different agreements.
One thing a straight-talking stock contractor will tell you up front: there are no guarantees. Bulls get hurt. Bulls have off days. Some great-looking calves never turn into bucking bulls at all. Eckroth’s advice in that same article is the right place to start: only put in what you can afford to lose.
Who’s on the papers
If your bull competes in American Bucking Bull, Inc. (ABBI) events, the paperwork matters as much as the handshake.
According to the ABBI 2025 rulebook, a bull owned by a partnership needs an ABBI competition agreement before he can be entered, and at least one of the partners has to be listed on the registration certificate as an owner. If your partnership or lease agreement keeps the owner’s name off the certificate, ABBI will only take the entry with a fully signed copy of that agreement attached. Animals also have to be in the inventory of the owner or partnership entering them. You’ll find the competition agreement on ABBI’s registration forms page.
Changing owners goes through ABBI too. The rulebook says a transfer needs the original pedigree signed over on the back plus a work order, and it can take up to two weeks. Rush transfers are available if you’re in a hurry.
So before the first entry fee gets paid, settle two things: whose name goes on the certificate, and who keeps the signed agreement where they can find it.
Who pays for what
Buying in is the easy check to write. The bills that come after are where partnerships get tested.
A bull costs money every single month. Feed. Vet visits. Hauling. Housing. Travel. Entry fees. Bucking Stock Talk’s partnership checklist puts it well: the purchase price can feel like an affordable mortgage, and then the upkeep shows up.
There are a few common ways to handle it. In the 50 percent competition deals Eckroth describes, the investor often pays the entry fees, and the costs of hauling, raising, feeding and training get negotiated. Another option is a flat fee up front, with the stock contractor covering the care. Some owners bill each partner for their share as the bills come in. Any of these can work. What doesn’t work is finding out which one you’re in after the vet bill arrives.
Here’s what a percentage split looks like. Say four partners own a bull at 40, 30, 20 and 10 percent, and one month’s bills come to $650: $300 in feed, a $150 vet visit and a $200 haul. (These are example numbers, not real prices.)
- The 40 percent partner owes $260.
- The 30 percent partner owes $195.
- The 20 percent partner owes $130.
- The 10 percent partner owes $65.
Easy enough for one month. Now do it every month, for every bull, with partners who each own a different slice of a different animal. That’s when the spreadsheet only one person understands starts running the operation.

Who gets paid, and how
The simplest rule is that winnings follow ownership. If the bull wins a $2,000 check and you own 20 percent, your cut is $400. But “simplest” doesn’t mean it’s the rule in your deal.
Some deals split every dollar the bull wins. Others split only certain events, so check which ones count. Sale money is its own conversation: if the bull gets sold, or a partner wants out, who gets what, and can a partner sell their share to someone else?
Then there’s the part nobody likes to talk about: actually getting everybody their money. Settling up by meeting somewhere to hand over checks works fine until somebody’s out of town for a month and three payouts are sitting in the glovebox.
Write down how winnings get split, which winnings count, and how and when the money moves. Your partners will thank you, and so will your accountant.

How everybody knows
This is the question that keeps partners happy, and the easiest one to skip.
A partner who lives three states away can’t see the bull eat. What they can see is what you send them. Ranchers have told us that keeping several owners up to date (photos, video, scores, bills) can eat a big chunk of the day, one text at a time. And the partner who doesn’t get an update is the one who calls after every haul.
Every partner should be able to see four things without asking:
- what percentage each partner owns
- what’s been spent, and what their share of it is
- what’s been won, and what they’ve been paid
- how the bull’s doing: his scores, his health and his video
If you’re buying into a bull that’s already competing, ask for his record of scores before you sign. Bucking Stock Talk also recommends asking how you’ll be kept up to date on his progress. It’s a fair question, and the answer tells you a lot about the person you’re about to partner with.

Taxes: the part to ask a pro about
We’re not going to tell you how to file. We will tell you why this deserves a real conversation with your tax preparer.
The IRS explains in Publication 541 that when two or more people carry on a business together and divide its profits, they’re generally treated as a partnership for federal taxes. Simply sharing expenses doesn’t count as a partnership by itself. A partnership that runs a business files a Form 1065, and each partner gets a Schedule K-1 showing their share.
One detail surprises people. The IRS’s instructions for Schedule K-1 say a partner may owe tax on their share of partnership income even if that money was never paid out to them.
Whether your bull deal counts as a partnership depends on the facts of your deal. That’s your tax preparer’s call, not ours. What we can tell you is that the conversation goes a whole lot faster when every bill, every check and every percentage is already written down.
Before you shake on it: a checklist
Handshake deals are a proud tradition, and plenty of good people have done straight deals on a handshake. They also leave the most room for a fight later. Bucking Stock Talk’s advice is to get the deal into a written contract before anybody signs, and we agree. Bring these questions to the table, and put the answers in writing:
- What percentage does each partner own?
- Whose name goes on the ABBI registration certificate, and do you have a competition agreement?
- What did each partner pay to buy in?
- Which ongoing bills are shared (feed, vet, hauling, housing, travel, entry fees), and how does each partner get billed?
- Who decides where and when the bull competes?
- How are winnings split, and do all events count?
- What happens if the bull is sold, or a partner wants out?
- What happens if the bull is injured or dies?
- How, and how often, does each partner get updates and video?
- How will you settle a disagreement?
If you can answer all ten without anybody getting quiet, you’ve got a partnership.
Keeping it all in one place
Buck Hub keeps each bull’s ownership percentages, shared bills, winnings and video in one place that every partner can see, so the answers to those four questions are always written down.

Frequently asked questions
How do bucking bull partners split costs?
Partners split costs however their agreement says. The simplest default is ownership percentage, so a 20 percent partner pays 20 percent of feed, vet and hauling. Some deals have the investor pay entry fees and negotiate the rest, and a flat fee up front, with the stock contractor covering care, is another option.
Do all partners have to be on the ABBI registration?
No. ABBI’s rules require at least one partner listed on the registration certificate as an owner, plus an ABBI competition agreement for the partnership. If the agreement keeps the owner’s name off the certificate, ABBI accepts the entry only with a fully signed copy of the agreement.
How are winnings split in a bull partnership?
The simplest rule is that winnings follow ownership percentage, so a 20 percent partner gets 20 percent of a check. Some agreements split only certain events. Write down which winnings count and how payouts reach each partner.
Is a bucking bull partnership a partnership for taxes?
It can be. The IRS generally treats two or more people who carry on a business and divide its profits as a partnership, while simply sharing expenses doesn’t make one. Whether a specific bull deal qualifies depends on its facts, so ask a tax preparer.
What should a bull partnership agreement include?
At minimum, each partner’s percentage, whose name is on the papers, which bills are shared and how they’re billed, how winnings and sale money are split, what happens if the bull is hurt or sold, and how partners get updates. Put it in writing before anyone pays.
