How to Register for Ontario Sales Tax?

For the one who owns a business or is planning to establish a start-up in Ontario, understanding how to register for the HST (Ontario Sales Tax) is crucial. 

Usually, taxes are seen as the horrible aspects of any business due to the rules and policies surrounding them.

Do not be so concerned with this as this is not just happening with you. 

Many entrepreneurs exhibit these traits as well, and here only the great knowledge of tax registration can help you. 

This blog will help you navigate the all necessary aspects of HST (Ontario Sales Tax), so you can ensure compliance with tax regulations. 

What is GST/HST?

GST/HST represents a value-added tax structure – basically a fee that you pay on most goods and services sold or provided in Canada. 

These are actually the two taxes combined: The GST (Goods and Services Tax) is a federal tax and on the other hand, the HST (Harmonized Sales Tax) is a provincial tax, and together the standard rate is 13%, consisting of a 5% GST and an 8% provincial portion.

However, some things do not come on the list of being taxed such as basic groceries, prescription drugs, and certain health services.

Also, the tax decreases from 13% to 5% on the purchase and sale of children’s clothes and books. 

Why Register for Sales Tax?

Sales tax registration is mandatory for businesses surpassing $30,000 in taxable revenues annually. 

This simply means if you have your own business in Ontario, and your firm generates around $30,000 a year, you need to register for sales tax. 

For this, you can charge your customer GST/HST to give it as tax to the government. 

It’s always best to start as early as possible; register yourself quickly so you can timely learn managing the money following the tax rules. 

It’s also a great idea to register the day you have stepped into your business or started it, to manage everything well. 

Prerequisites for Registration

Knowing what would be required to make a registration for Ontario Sales Tax will help you make a smoother regular compliance, and avoid the potential risks. 

This section has mentioned the necessary steps to prepare for the Harmonized

Sales Tax (HST) process.

Determine Your Obligation to Register

Your business must register for HST if it earns more than $30,000 per year from the sale of goods. 

A small business that earns a revenue of under $30,000 can choose to register if they decide to, but it is not mandatory. 

Taxi drivers and drivers that drive for ride-sharing apps are examples of a few businesses that have to register regardless of their revenue.
