Reduction In Tax Liability

Good Day;

Quickly, my situation is changing from an employee to consultant, for the past 4 years I have paid my taxes and taken my legal deductions such as children, LTF, RTF, Insurance for Mother in-law, family deductions, etc...

Now with my new situation, I will be working for a firm as a consultant without taxes being taken out every month for me, so I must pay my own tax bill. Do I have any additional benefits that I can achieve by doing

this, such as I pay my own health and life insurance now, can that help reduce my tax burden? If I work from home can I take some of my rent, anything like this? I assume I need a good tax accountant but I was

hoping some of you may have some insight to share before I go to the accounting firms?

Any cautionary tales to share or advice is welcome.

Regards

CHS
