A secondary will may be worth discussing with your lawyer when planning for shares and other interests in a private corporation.

If you have set up a dental corporation, consider discussing a corporate will with an Ontario estates lawyer. Sometimes called a secondary or restricted will, it can form part of a broader estate plan.

Why consider a secondary will?

  1. Estate Administration Tax: certain assets dealt with under a properly structured secondary will may not need to be included in a probate application. This can affect the value on which Estate Administration Tax is payable. It does not mean every corporate asset automatically avoids probate or tax.
  2. Timing and administration: where the relevant assets can be administered without a probate certificate, a secondary will may help reduce delays. Probate timing varies, and an executor may need to plan for estate expenses while an application is processed.
  3. Separating assets: a lawyer can help determine which assets belong under your primary will and which can appropriately be addressed under a secondary will.
  4. Business continuity: coordinated estate and corporate documents may help those responsible for the business deal with shares and ongoing operations after a death.

Understanding the tax example

For Ontario estate-certificate applications under the current rules, no Estate Administration Tax is payable on the first $50,000 of the estate value, and $15 is payable per $1,000 or part of $1,000 above that amount. A taxable estate valued at exactly $1,000,000 would therefore attract $14,250. Any reduction from using multiple wills depends on the assets, total estate value and legal requirements.
