Industries We Work With
We work with the financial reality of your specific industry, not a generic template applied to every client. Toronto's business community spans real estate, trades, professional services, eCommerce, and more, and each comes with its own CRA obligations, filing requirements, and bookkeeping needs.
About AccTax
AccTax is an accounting and tax firm based in Kitchener, Ontario, providing monthly bookkeeping, tax filing, payroll, CRA correspondence, and company incorporation services to resident and non-resident Canadians.
Over time, the group expanded with additional entities incorporated in 2014, 2023, 2024, and 2025. Today, Acctax brings together the combined experience and resources of all affiliated entities under one unified vision.
Our team includes CPAs, ICMA and ACCA professionals, MBAs, tax specialists, and business advisors. We handle bookkeeping, tax filing, payroll, CRA correspondence, and company incorporation, with offices in Kitchener, Waterloo, and Cambridge, serving Toronto and GTA businesses remotely.
We hold authorized representative access with CRA, which means we communicate with CRA directly when questions arise about any filing we prepared.
One Firm. Books, Tax, and CRA Support Connected.
Most Toronto businesses split bookkeeping and tax between two separate providers. That gap is where records get inconsistent, context gets lost, and CRA questions become harder to answer.
AccTax connects monthly bookkeeping directly to GST/HST returns, payroll records, and year-end corporate filings. When CRA follows up on a return we filed, the records that support it already exist because we built them. This is how Ontario businesses avoid the year-end scramble that comes from having two firms that never speak to each other.
Everything Under One Roof
We handle bookkeeping, tax filing, payroll, CRA correspondence, and company incorporation under one roof, which means the records we build throughout the year feed directly into the returns we file. Nothing gets lost between providers because everything stays with the same firm.
Remote Digital Workflow
Based in Ontario with offices in Kitchener, Waterloo, and Cambridge, we serve Toronto and GTA businesses remotely with the same workflow and service scope available to local clients.
Authorized CRA Representatives
We hold authorized representative access with CRA, which means we can communicate with CRA directly when questions arise about any filing we prepared.
