Yes, generally. Being the sole shareholder of your company does not exempt it from complying with the applicable annual corporate formalities.
When a company has only one shareholder, it is generally not necessary to hold a physical annual meeting. The sole shareholder can instead record decisions within their authority in writing, either through written resolutions or by way of resolutions, in accordance with the rules set out in applicable law.
These decisions may include matters relating to the election of directors and other issues that must be submitted annually to shareholders.
However, it's important to distinguish between your role as a shareholder and that of a director. Being the sole shareholder does not necessarily mean you are also the sole director. Decisions that fall under the purview of the board of directors must be made and documented in accordance with the rules applicable to directors.
If you are both the sole shareholder and the sole director, you may have to sign resolutions related to your respective roles. It remains important to distinguish between decisions made as a shareholder and those made as a director.
The annual resolutions should be kept in the minutes book along with the other corporate documents of the company.
In summary , even if you are the sole shareholder, the annual decisions that fall within your authority must generally be documented. When you are also a director, the decisions that fall under the board's purview must be recorded separately according to the applicable rules.
