When making sales inter-provincially, it's important to to select the correct sales tax codes. QuickBooks Online makes it easy to account for sales tax from anywhere in Canada, and I'd be happy to show you how.
When it comes to determining the appropriate sales tax code, the CRA and the Government of British Columbia are your best resources. The tax code you select is based on the province that your customer resides in, rather than where your company is based. In this situation, British Columbia does things a little differently, so depending on what services you're providing, the amount of tax you charge might vary. Here are a couple links that I know will point you in the right direction:
In order to select the appropriate tax codes for your customer it's important that you've set up the codes in the Tax Centre. Here's how you can set up additional tax codes in QuickBooks Online:
Navigate to the Taxes tab from the left menu.
Within the Sales Tax page, select Manage sales tax from the upper right corner.
Click Add tax.
To Start tracking in a new province click the corresponding green Add button.
Choose the province or territory from the dropdown menu.
If required, enter your filing information for the province's tax agency.
Since your customer is in British Columbia, you'll need to add the tax code and agency for the BC Ministry of Finance. Once complete you'll see new codes for GST/PST BC which represents the combined provincial and federal tax, and just PST BC which is provincial sales tax only. You'll be able to select these codes on transactions you enter going forward.
You'll be ready to collect and remit taxes from across the country in no time!
