Tax Services for Self-Employed Professionals in Mississauga
Working for yourself means handling your own income records, expenses and tax obligations. Yass Financials helps self-employed professionals, freelancers and contractors in Mississauga keep their records organized, file accurately and plan for what they will owe.

Tax support built for people who work for themselves
How are self-employed people taxed? Self-employed individuals file a personal income tax return and report their business income and expenses on form T2125, which is part of that return. Because no employer withholds tax, they are responsible for setting money aside, and the CRA may require them to pay by instalments during the year.
Yass Financials works with sole proprietors, freelancers, consultants and contractors who want their taxes done correctly and their records in order, without having to become bookkeepers themselves.

Home office expenses
The CRA allows a deduction for the business use of a workspace in your home if it is your principal place of business, or if you use it only to earn business income and regularly meet clients there. See the CRA's business-use-of-home expenses page.
This page is general information. Which expenses and rules apply to you depends on your business, and is reviewed in your consultation.
Frequently asked questions
Do self-employed people file a different tax return?
No. Self-employed individuals file the same personal income tax return, and report business income and expenses on form T2125, Statement of Business or Professional Activities, which is part of that return.
What expenses can a self-employed person deduct?
Generally, reasonable expenses incurred to earn business income, such as supplies, software, advertising, professional fees and a share of vehicle and home costs when the CRA's conditions are met. Which ones apply depends on your business, so they are reviewed with you.
Do I need to register for GST/HST?
Most businesses must register once their taxable sales go over $30,000 in a single calendar quarter or over four consecutive calendar quarters. You can also register voluntarily below that amount. We can help you work out where you stand. CRA: when to register.
Can you keep my books during the year too?
Yes. Monthly bookkeeping keeps income and expenses organized as you go, so your return starts from records that are already complete. More about bookkeeping.
