Yes, lawyers in Ontario can incorporate their practice through a Law Professional Corporation. For many lawyers, this can be a smart step when their practice is growing, income is becoming more consistent, or they want a better structure for tax planning and long-term business management.
But incorporation for lawyers is not the same as setting up a regular corporation. Since legal services are regulated in Ontario, lawyers must follow the rules set by the Law Society of Ontario, the Business Corporations Act, the Law Society Act, and related by-laws. Lawyers and licensed paralegals cannot practice through a professional corporation until the corporation receives a Certificate of Authorization from the Law Society of Ontario.
This guide explains how incorporation works for lawyers in Ontario, what the key benefits are, what rules must be followed, and when it may make sense to speak with an accountant before moving ahead.
What Is a Law Professional Corporation?
A Law Professional Corporation is a corporation created for the purpose of providing legal services in Ontario. It is a separate legal entity, but it is still subject to professional rules that apply to lawyers and paralegals.
This means the corporation can own business assets, earn income, pay expenses, file corporate tax returns, and manage business finances. But the legal services must still be provided by licensed professionals who meet Law Society requirements.
The Law Society of Ontario states that all shareholders of a professional corporation must be lawyers entitled to practise law in Ontario or licensed paralegals entitled to provide legal services in Ontario.
So, unlike a regular business corporation, a Law Professional Corporation has limits on:
- who can own shares
- who can act as a director
- what services the corporation can provide
- how the corporation can be named
- when it can begin operating
This is why lawyers should not treat incorporation as a simple form-filling task. It affects tax, legal structure, bookkeeping, compliance, and future planning.
Business Structures Available to Lawyers in Ontario
Before incorporating, it helps to understand the main business structures lawyers may use in Ontario.
Sole Proprietorship
A sole proprietorship is often the simplest structure. The lawyer operates under their own name or registered business name. Income and expenses are reported personally.
This structure may work for a new lawyer or solo practitioner with lower income and simple operations. But as the practice grows, it may become less useful for tax planning and long-term business organization.
Partnership
A partnership allows two or more lawyers to practise together and share income, expenses, duties, and responsibilities.
This can work well when lawyers want to combine skills and resources. But a partnership needs a clear agreement covering profit sharing, decision-making, client files, exits, and liability.
Limited Liability Partnership
A limited liability partnership, or LLP, is a common structure for law firms with multiple partners. The Law Society notes that an LLP can help protect the personal assets of individual partners for professional liability purposes, depending on the structure and requirements involved.
Professional Corporation
A professional corporation may be useful for lawyers who want a more structured business setup. It can support tax deferral, retained earnings, corporate savings, payroll planning, and retirement planning.
But it does not remove professional responsibility. Practising law through a professional corporation does not limit a lawyer’s professional liability. The Law Society clearly notes that a professional corporation may offer tax deferral benefits, but it does not limit professional liability.
Can Incorporation Protect Lawyers from Liability?
This is one of the most important points to understand.
A professional corporation can provide some business structure benefits, but it should not be seen as a way to avoid professional liability. Ontario’s Business Corporations Act states that professional incorporation does not limit the professional liability of shareholders.
In simple terms, a lawyer remains responsible for their professional work. If there is a professional negligence issue, incorporation does not automatically protect the lawyer the way some business owners may expect from a regular corporation.
That said, incorporation may still help separate some business matters from personal finances. For example, the corporation may hold business bank accounts, manage operating expenses, and enter into certain contracts. But professional obligations, insurance requirements, and Law Society rules still apply.
This is why lawyers should review incorporation with both a legal advisor and an accountant before deciding.
Main Benefits of Incorporating a Law Practice
Incorporating is not right for every lawyer. But when the practice has steady income and enough profit left after personal living needs, it can offer useful advantages.
Better Tax Planning
One of the main reasons lawyers consider incorporation is tax planning.
A Canadian-controlled private corporation that qualifies for the small business deduction may pay a lower corporate tax rate on eligible active business income. Federally, the net tax rate for Canadian-controlled private corporations claiming the small business deduction is 9%. Ontario also has a small business deduction that can reduce the Ontario rate on eligible small business income.
This does not mean a lawyer simply “saves tax” by incorporating. If money is taken out personally as salary or dividends, personal tax still applies. The planning benefit often comes from leaving some after-tax profit inside the corporation for future business use, investment, or retirement planning.
Income Deferral
If a lawyer does not need to withdraw all business profit each year, the corporation may allow some income to stay inside the company.
This can create a tax deferral opportunity. The corporation pays corporate tax first, and personal tax is triggered later when money is paid out to the shareholder through salary, dividends, or another approved method.
This can be useful for lawyers who have strong cash flow and want to save for future costs, hiring, technology, office improvements, or slower business periods.
3. Cleaner Business Finances
A professional corporation can make business finances easier to organize.
The corporation should have its own bank account, bookkeeping system, payroll setup if needed, and accounting records. This helps separate personal spending from business expenses.
For lawyers, this is especially important because clean records support better tax filing, better cash flow tracking, and easier compliance.
Cleaner Business Finances
An incorporated lawyer may pay themselves through salary, dividends, or a mix of both, depending on their situation.
Salary can create RRSP contribution room and may support CPP contributions. Dividends may offer flexibility, but they do not create RRSP room. The right mix depends on income level, retirement goals, cash flow, and tax planning needs.
Care is also needed when paying family members or issuing dividends to related persons. Canada’s Tax on Split Income rules can apply to certain amounts received by adults from a related business, including certain dividends.
So, income splitting should never be handled casually. It should be reviewed properly before money is paid out.
Retirement Planning Options
Once incorporated, a lawyer may have access to more advanced retirement planning options in some cases.
For example, certain incorporated professionals may consider an Individual Pension Plan, depending on income, age, contribution goals, and long-term planning needs. This is not needed for every lawyer, but it can be useful for higher-income professionals who want structured retirement savings.
Professional Image and Long-Term Growth
A professional corporation may also give the practice a more formal business structure. This can help when hiring staff, adding systems, planning succession, entering leases, managing payroll, or expanding the practice.
It also makes the practice easier to organize from an accounting and management point of view.
Key Requirements for Lawyers Incorporating in Ontario
Lawyers cannot simply create a corporation and start using it for legal services. There are specific steps and requirements.
Incorporate Under Ontario Rules
The corporation must be set up under the Ontario Business Corporations Act. The articles of incorporation must meet Law Society requirements. If the articles do not comply, the corporation may need to amend them before approval.
Use a Compliant Corporation Name
The corporation’s name must follow the rules for professional corporations. In general, the name must include “Professional Corporation” or the required equivalent.
The name should also follow Law Society naming rules and should not mislead the public.
Apply for a Certificate of Authorization
This is a major step.
A Law Professional Corporation cannot practise law or provide legal services until it receives a Certificate of Authorization from the Law Society of Ontario.
The application generally includes information about the corporation, shareholders, directors, officers, and articles of incorporation.
The Law Society currently states that the application fee is $395.50, which includes $350 plus HST. It also states that completed applications require processing time, so lawyers should apply well before they plan to operate through the corporation.
Renew the Certificate Each Year
The Certificate of Authorization must be renewed each year before December 31.
The current renewal fee listed by the Law Society is $226, which includes $200 plus HST. Only shareholders of the professional corporation are allowed to pay the renewal fee and update certain corporation details.
If the certificate is not renewed by the deadline, the corporation may no longer be allowed to practise law or provide legal services in Ontario.
Register for a Business Number and CRA Accounts
After incorporation, the corporation will need a Canada Revenue Agency Business Number. It may also need CRA program accounts, such as GST/HST and payroll.
CRA now requires business number and CRA program account registrations to be done online through Business Registration Online. Business registration by phone is no longer available.
Register for HST When Required
Law firms generally provide taxable services, so HST registration must be reviewed carefully.
A business usually has to register for GST/HST if it makes taxable supplies in Canada and exceeds the $30,000 small supplier threshold over the required period. CRA explains that businesses must register within the required timeline once they stop being a small supplier.
Some businesses may also register voluntarily if they make taxable supplies in Canada, even before they cross the threshold.
For lawyers, HST planning matters because it affects invoicing, filing deadlines, input tax credits, bookkeeping, and cash flow.
Accounting and Tax Responsibilities After Incorporation
Once a lawyer incorporates, the accounting work becomes more detailed.
The corporation will usually need:
- corporate bookkeeping
- a separate business bank account
- annual corporate tax return filing
- HST filing, if registered
- payroll setup, if salary is paid
- dividend tracking, if dividends are paid
- shareholder loan tracking
- financial statements
- expense categorization
- recordkeeping for CRA compliance
This is where many professionals underestimate the ongoing work. Incorporation is not only a one-time setup. It creates an ongoing filing and recordkeeping structure.
A missed HST deadline, incorrect payroll filing, poor bookkeeping, or unclear shareholder loan account can create tax issues later.
When Does It Make Sense for a Lawyer to Incorporate?
Incorporation may make sense when:
- the practice is earning steady profit
- the lawyer does not need to withdraw all income personally
- there is a plan to retain money inside the corporation
- the practice has growing expenses or staff
- the lawyer wants cleaner business records
- retirement planning is becoming more important
- the practice is moving from solo work to a more formal firm structure
It may not make sense if the lawyer is just starting out, has low profit, withdraws all income for personal use, or does not want the added cost of corporate filings and bookkeeping.
The decision should be based on numbers, not guesswork.
An accountant can compare the cost of staying as a sole proprietor versus incorporating. This comparison should include corporate tax, personal tax, accounting fees, HST filing, payroll costs, legal setup fees, and expected retained earnings.
Common Mistakes Lawyers Should Avoid When Incorporating
Incorporating Without a Tax Plan
Incorporation alone does not guarantee tax savings. The benefit depends on income level, withdrawal needs, retained earnings, and how compensation is planned.
Ignoring HST and Payroll Setup
Once the corporation is active, HST and payroll rules need to be handled correctly. Late filing or poor setup can cause avoidable penalties and stress.
Mixing Personal and Corporate Funds
A corporation should have a separate bank account. Personal expenses and business expenses should not be mixed.
Assuming Liability Is Fully Limited
This is a common misunderstanding. A Law Professional Corporation does not remove professional liability. Lawyers still remain responsible for their professional work.
Forgetting Annual Renewal
The Certificate of Authorization must be renewed every year before the deadline. Missing the renewal can affect the corporation’s ability to provide legal services.
How Multi Tax Services Can Help
Incorporating a law practice is not only a legal step. It is also a tax and accounting decision.
Multi Tax Services helps professionals and small business owners in London, Ontario with practical accounting support, including:
- corporate tax filing
- bookkeeping setup
- HST registration and filing
- payroll setup
- year-end financial statements
- business expense tracking
- tax planning support
- CRA account guidance
- financial record organization
For lawyers thinking about incorporation, an accountant can help answer an important question: Will incorporation actually help your practice financially, or will it only add more cost and paperwork?
That answer depends on your income, expenses, withdrawal needs, growth plans, and long-term goals.
Conclusion
Lawyers in Ontario can incorporate, but the process must be handled carefully. A Law Professional Corporation can help with tax planning, retained earnings, cleaner bookkeeping, payroll planning, and long-term business growth. But it also comes with strict Law Society rules, annual renewal duties, CRA registration, HST responsibilities, and corporate tax filing.
Most importantly, incorporation does not remove professional liability. It should be viewed as a business and tax planning structure, not a shield from professional responsibility.
Before incorporating, lawyers should speak with both a legal advisor and an accountant. MultiTax Services can help review the accounting and tax side of the decision so lawyers can understand the real costs, benefits, and filing responsibilities before moving forward.
