For many, dog breeding isn’t just about producing litters—it’s about passion, dedication, and improving a breed’s quality. Yet, while breeders pour countless hours and resources into their work, the IRS often sees things differently. Under the hobby loss rules, what feels like a legitimate business to a breeder can quickly be classified as a “hobby,” resulting in harsh tax consequences.
The IRS has specific guidelines under Internal Revenue Code Section 183—commonly known as the “hobby loss rules.” These rules are designed to prevent taxpayers from deducting losses from activities that aren’t truly businesses but are pursued more for recreation or personal satisfaction.
If an activity doesn’t meet the IRS’s definition of a business, the breeder may lose the ability to deduct expenses, even if those expenses are real and significant.
Dog breeding is often viewed as a labor of love rather than a money-making enterprise. Many breeders genuinely invest more into their animals’ health, facilities, and care than they ever recover through puppy sales. Unfortunately, the IRS may interpret consistent losses as proof that breeding isn’t a “for-profit” venture.
That means:
Income from sales is taxable
Expenses may not be deductible if the breeding isn’t recognized as a legitimate business
The breeder may end up paying taxes on “phantom profits”
The IRS applies a profit motive test to determine whether breeding is a business or a hobby. They look at factors such as:
Recordkeeping and financial management
Time and effort put into the activity
The breeder’s expertise and professional conduct
Whether the activity makes a profit in at least 3 of 5 consecutive years
For dog breeders, this is particularly challenging—especially since producing quality litters can take years of planning, investment, and care before profits appear.
Imagine a breeder who spends $15,000 annually on veterinary care, nutrition, show costs, and facilities but only earns $10,000 from puppy sales. If the IRS classifies the breeding as a hobby, they must report the $10,000 as taxable income but cannot deduct the $15,000 in expenses.
That’s a punishing result: breeders essentially get taxed for following their passion.
Dog breeders who want to protect themselves should consider:
Keeping meticulous financial records – Track every expense and revenue.
Creating a written business plan – Show intent to make a profit.
Separating personal and business finances – Use dedicated accounts.
Seeking professional advice – A tax advisor familiar with agriculture or animal-related businesses can help.
Documenting expertise and effort – Time spent, breeding plans, participation in shows, and marketing all help prove business intent.
While dog breeding is often driven by love for animals rather than financial gain, the IRS doesn’t see it that way. Without careful planning and documentation, breeders risk being penalized under hobby loss rules.
For passionate breeders, the key is to treat their work as seriously as any other business—because in the eyes of the IRS, that’s exactly what it needs to be.
