PetTax: Pet Tax Deduction Eligibility Checker

Problem Statement

Many pet owners with legitimate tax-deductible expenses — service animals, business guard animals, performing pets, foster animals — overpay on taxes simply because they don't know the IRS qualification criteria apply to them.

Solution

PetTax walks users through an eligibility checker that maps their pet's role against IRS deduction categories. It produces a clear result with the applicable deduction type and relevant guidance — updated for tax years 2025 and 2026.

Our Approach

We translated the relevant IRS guidance on animal-related deductions into a short decision tree of plain-language questions about the pet's role, purpose, and documentation — service work, business use, performing income, or fostering through a qualified organization. Each answer path resolves to a specific deduction category with a summary of what the IRS typically requires as supporting evidence, rather than a vague 'consult a tax professional' dead end.

Key Features

• •Plain-language decision tree mapped directly to IRS animal-deduction categories
• •Clear pass/fail eligibility result instead of ambiguous general guidance
• •Content kept current for tax years 2025 and 2026 as rules are confirmed

Results

PetTax gives pet owners a fast, specific answer instead of generic tax-blog advice, and demonstrates how a narrow, well-scoped eligibility question can be fully automated without needing a human advisor in the loop for the initial screening step.

Challenges

IRS guidance on animal-related deductions is scattered across multiple publications and rulings rather than one clear source, so the hardest part was structuring the decision tree to avoid false positives — telling someone they likely qualify when their situation is actually borderline.

Lessons Learned

For eligibility-style tools tied to tax or legal rules, being conservative on edge cases (routing them to 'likely qualifies, confirm with a professional' rather than a hard yes) builds more user trust than optimizing for a clean binary answer.
