Professional Tax Accountant Mississauga

In Canada, all individuals, small businesses, and corporations are required to file income tax returns each year. There are several reasons why you should leave this to a financial firm. GTA Professional Corporation, we know what taxes to file, when to file, and how to file. Consult our tax accountant in Mississauga for all your tax preparation requirements.

Individuals have to file tax returns detailing all their sources of income in T1 personal income tax returns. We will help you to fill your employment income for the year and guide you on other applicable incomes.

We help you file small business taxes, which depend on how the business is structured. Sole proprietorships and partnerships report their business income tax on their T1 personal income tax returns. You and your small business are taken to be one and the same thing. The T1 income tax return package comes with Statement of Business or Professional Activities (Form T2125) which you will use to report the business income.

Documentation We Assist Clients With Are:

Incorporated businesses report their income on the T2 corporate tax return. Unlike a small sole proprietorship or partnership, an incorporated business is taken as a separate entity and it, therefore, has to file its own tax return.

  • T4 slips (for those who have employment and business income)
  • T4A (for those earning commissions and the self-employed)
  • T5013 (Partnership Income)
  • T3 (Income from Trusts)
  • T5 (Investment Income)
  • RRSP contribution slips
  • Medical and dental receipts

Business & Personal Tax Accountant Mississauga

Hiring a pro for business tax return is important because missing even a single entry could mean fines and other sanctions from the Canada Revenue Agency. Missing out on legitimate Canadian income tax deductions is also detrimental to you. At GTA Professional Corporation, our tax accountant knows from training and experience the deductions that businesses should claim. Examples are:

  • Home Maintenance & Home Ownership Income Tax Deductions for home-based business owners
  • SR&ED for those involved in R&D
  • Gifts to Employees

The Canada Revenue Agency has rules for vehicle business expenses, employing your spouse or child, travel-related expenses, advertising expenses and other business expenses that fall into the Agency’s ‘other’ category. We understand these rules and will ensure you do not pay a cent more than you should.

You Should Come To Us For Mississauga Bookkeeping Services...

  • If you are a small to medium-size company or an NGO and you do not have resources to hire an in-house accountant

To register as a corporation in Canada, you need to:

  • Incorporate the business (get articles of incorporation) through provincial/territorial incorporation or federal incorporation
  • Get a Corporation income tax account and a federal business number from the Canada Revenue Agency
  • Register as an extra-territorial or extra-provincial corporation in all other Canadian jurisdictions where you will be doing business
  • Apply for any licenses and permits that your business will need to operate

Although the registration of these accounts is sometimes streamlined (you can sometimes get your business number, provincial registration, and tax accounts as part of the incorporation process), this is not true for all cases.

Professional Tax Accountant Specializing in Corporations

At GTA Firm, we will assist you with the provincial or federal incorporation of your small business. Here's how we can help.

We will assist you to fill the business or the not-for-profit form as well as forms for operating an extra-provincial corporation in Ontario if you are not a Mississauga native.

We will then assist you to file Articles of Incorporation (Form 1 under the Business Corporations Act) as well as supporting documents with the Ministry of Government and Consumer Services.

The law requires that a corporation files an Initial Return/Notice of Change (Form 1 under the Corporations Information Act) within 60 days of the date of incorporation. We will assist you to make this filing.

If we file online, we will get all first directors to complete a Consent to Act as First Director (Form 2 under the Business Corporations Act). If filing via mail or in person, we will get the form from you and ensure the forms are locked away at your offices in case the Ministry of Government and Consumer Services ever decides to peruse them.

If you want to dissolve the business due to any reason, our CPA understands the processes of dissolving business corporations either voluntarily or involuntarily.

HST Filings

Many provinces, including Ontario, have adopted a Harmonized Sales Tax (HST). HST harmonizes the provincial sales tax with federal government’s Goods and Services Tax (GST). In Ontario, an HST of 13% was introduced in 2010.

We will guide you to ensure you pay the right amount of sales tax. We will keep track of your HST and assist you with tax filing. Our other services are:

  • We will assist you to determine which goods and services are Taxable, Zero-Rated or Exempt.
  • We will help you fill the GST/HST Return form, keeping in mind that the Canada Revenue Agency requires businesses to collect HST from their customers and to remit the same. Note the law requires that you must remit on the reporting period even when you’ve not collected tax during the period (with zero remittance).
  • We will ensure we remit GST/HST Returns within the reporting period (which is quarterly for most businesses and monthly for businesses with a revenue of over $6 million in annual taxable supplies.
  • We will help you determine the GST/HST expenses that qualify as ITCs (Input Tax Credits) since not all business-related expenses are eligible.
