The CPA Who Understands
ABA Practitioners
Most CPAs don't know CPBAO from CRA. We specialize in behavior analysts, BCBAs, RBTs, and ABA therapy practice owners across Canada — handling the complex tax and accounting issues general CPAs miss.
We handle everything ABA-specific:
- Professional Corporation (PC) setup for BCBA practitioners
- CPBAO compliance — we know what's required and what isn't
- Contractor vs. employee classification — avoid CRA risk
- ABA-specific tax deductions: BACB fees, software, mileage, home office
- OAP funding flow, RBT payroll, and HST on therapy services
- Tax strategy to keep more of what you earn
Whether you're a solo BCBA contractor, running a multi-therapist practice, or anywhere in between — we've incorporated ABA businesses, handled OAP funding payroll, and optimized tax strategy for behaviour analysts across Ontario and Canada.

Ontario Small Business Deduction 2025: Rates, Eligibility, and Planning Strategies
Ontario CCPCs pay as little as 12.2% corporate tax on the first $500,000 of active business income — compared to the top personal rate of 53.5%. Understanding the small business deduction rules is the cornerstone of corporate tax planning in Ontario.
“Getting hit with a CRA audit notice for my bakery almost made me close my doors. Adapt stepped right in, took over all communication with the CRA, organized my old boxes of receipts, and prepared a rock-solid response. They proved all my HST claims were valid and got the auditor to drop the payroll dispute entirely. They literally saved me from a penalty that would have ruined me.”
“I highly recommend Adapt Accounting to other local business owners. Managing a growing construction company meant my finances were getting sloppy very fast. They implemented a clear tracking system for our jobs and cleaned up our entire ledger in record time. Really good bookkeeping that lets me see exactly which projects are actually profitable for us.”
“This was the easiest tax season I've ever had and it's all thanks to this team. No more printing spreadsheets and hunting for receipts in my car. They set me up on a simple app where I just upload pictures of my expenses on the go. Really good bookkeeping makes my year end ready to go without any stress.”
“The team here is amazing! They took over our corporate taxes and made the whole T2 process feel like a breeze. Great people to work with.”
“I recently started working with this CPA-certified firm for both my personal and business needs, and I've been very impressed. Professional, responsive, and genuinely invested in helping their clients succeed.”
“They helped me file my T1 return, and made the process easy and fast. They had so much professionalism and helped guide me every step of the way.”
