Frequently asked tax questions

KB Fiscalité answers the Quebec tax questions clients ask most often, incorporation, corporate and personal tax returns, GST/QST, business transfers, estates and tax audits.

What is this FAQ for?

This FAQ gathers the questions KB Fiscalité’s tax professionals are asked most often, incorporating a business, T2 and CO-17 corporate returns, GST and QST, transferring a business, estates and tax audits. Each answer opens with the short version in one or two sentences, then adds the context that matters, grounded in established Quebec and Canadian tax rules.

These answers are general in nature. Tax outcomes always turn on the facts of your file (how your corporation is structured, your family situation, whether a sale or transfer is on the horizon) and a strategy that works for one taxpayer can prove costly for another. Have your own situation reviewed before you act.

Who answers these questions?

The answers reflect the practice of Thierry Bouchard, a tax lawyer and member of the Barreau du Québec since 2009, and Ante Kumanović, CPA, who holds a master’s degree in taxation from HEC Montréal, the firm’s co-founders in Vaudreuil-Dorion. The firm’s professionals are members of the APFF. If your question is not covered here, write to info@kbtax.ca or call (514) 394-0848.

What does tax planning actually involve?

Tax planning means structuring your affairs (how your business is held, how you pay yourself, where your assets sit) so that transactions attract the least tax the law allows, before they happen. It serves businesses and incorporated professionals as much as families preparing a transfer or an estate. KB Fiscalité reviews your situation and your objectives, then implements the structure chosen.

What is a discretionary family trust used for?

A discretionary family trust holds assets, most often shares of a private corporation, for the benefit of family members, while giving the trustees discretion over who receives income and capital. Properly structured, it supports income splitting, asset protection and estate planning. Trusts follow strict rules, including the 21-year deemed disposition rule, so they should be set up and monitored by a tax professional.

When should I consider reorganizing my corporation?

A corporate reorganization is worth considering before a sale of the business, when a new shareholder comes in, to purify the corporation so its shares qualify for the lifetime capital gains exemption, or to separate real estate from operations. Done at the right time, a reorganization generally proceeds by tax rollover, without immediate tax. The essential rule, reorganize before the transaction, never after.

Can I transfer my business to my children tax-efficiently?

Yes, a properly planned intergenerational business transfer can offer tax treatment comparable to a sale to a third party, particularly since Bill C-208 addressed transfers to the next generation. Where the shares are qualified small business corporation shares, the seller may be able to claim the lifetime capital gains exemption. The conditions are strict and the structure matters. KB Fiscalité guides families from the initial plan through to implementation.

How much does it cost to incorporate in Quebec?

The cost of incorporating depends on what your situation requires. The share structure, whether a family trust is involved, a shareholder agreement, or the specific rules that apply to incorporated professionals. A proper incorporation includes the articles, the legal organization of the corporation and the minute book, not just a filing with the registry. KB Fiscalité reviews your needs first, recommends the right structure, then quotes the mandate accordingly.

Should I incorporate my professional practice?

Incorporation usually becomes worthwhile when your practice earns more than you need to live on, because a corporation lets you defer tax on income left inside the company. Physicians, dentists, lawyers, notaries and other members of professional orders must also follow their order's specific incorporation rules. KB Fiscalité assesses whether incorporation makes sense in your situation and handles the entire setup.

When is a corporation's tax return due in Quebec?

A corporation must file its federal T2 return and its Quebec CO-17 return within six months of its fiscal year-end. Any balance of tax owing is due earlier, two or three months after year-end, depending on the corporation's situation. Filing late triggers penalties and interest, so these deadlines deserve as much attention as the return itself.

When is my personal tax return due?

Personal income tax returns are due April 30. Self-employed individuals and their spouses have until June 15 to file, but any balance owing is still payable by April 30. KB Fiscalité also prepares returns for trusts and non-residents, two types of files that call for specialized expertise.

What are the GST and QST rates in Quebec?

The federal GST is 5% and the Quebec QST is 9.975%, which together add just under 15% to most taxable sales in Quebec. Registered businesses collect these taxes and can generally recover the tax paid on their own purchases through input tax credits and refunds. Registration, collection and recovery rules carry many exceptions, the firm helps businesses get them right.

What should I do if Revenu Québec audits my business?

If Revenu Québec or the CRA announces an audit, speak with a tax professional before you hand over documents or sign anything. What you provide at the start of an audit shapes the entire file, including any eventual tax dispute. KB Fiscalité acts under audit mandates and represents clients before the tax authorities, up to and including challenging assessments when warranted.

What taxes apply when someone dies in Quebec?

When a person dies, they are deemed to have disposed of their property, which can trigger tax on accrued gains in their final return. A spousal rollover often defers that tax when property passes to the surviving spouse. The estate itself may also have to file its own returns while it holds property, and sound post-mortem planning can reduce the overall tax burden.

How does KB Fiscalité help estate liquidators?

An estate liquidator, Quebec's term for an executor, is personally responsible for certain tax obligations, including filing the deceased's returns and obtaining clearance certificates before distributing property. KB Fiscalité prepares the deceased's and the estate's tax filings, designs the post-mortem plan, and assists heirs and the liquidator at every step. That support protects the liquidator and prevents unpleasant tax surprises.

Do you work with Montreal businesses?
