Self-employed tax filing in London: FAQ
Quick answers to what people ask us most.
Do you offer self-employed tax filing in London?
Yes. We provide self-employed tax filing to individuals and businesses in London and Southwestern Ontario. You can meet with us by phone or video and share documents securely online. Call (647) 527-4970 to get started.
What expenses can I deduct as a self-employed person?
Generally, expenses you incur to earn business income: supplies, software, advertising, insurance, professional fees, a reasonable share of home office costs and business use of a vehicle. Personal expenses are not deductible, and good records matter.
Do I need to pay tax instalments?
If your net tax owing is more than $3,000 in the current year and in either of the two previous years, the CRA generally requires instalments. Your preparer can calculate them and remind you of the due dates.
When do I have to register for GST/HST?
You must register once your worldwide taxable revenue passes $30,000 over four consecutive calendar quarters. You can also register earlier, which lets you recover GST/HST paid on business costs.
How much does self-employed tax filing cost in London?
Fees depend on the scope and complexity of your situation. After a free consultation we give you a clear quote before any work begins.
