Updated Checked by the Tax-Services.ca editorial team How we check
Bookkeeping requirements in British Columbia come from three places. The CRA wants records kept for six years, the province wants PST records for five, and a BC company must also keep adequate accounting records under the Business Corporations Act. Keep everything six years and you cover the longest of them.
What does BC add to the federal rules?
Federally, section 230 of the Income Tax Act says a business must keep books that let its tax be determined. The CRA’s retention period is six years from the end of the last tax year the records relate to.
British Columbia adds its own tax, the PST, and its own company law. A BC business that sells taxable goods or services collects PST as well as GST, so it needs records for both.

Do you have to register for PST?
Not always. A small seller can stay out of PST registration when its gross revenue from retail sales of eligible goods, software and services was $10,000 or less over the previous 12 months and is expected to be $10,000 or less in the next 12. The seller also can’t have established business premises. If you’re above that line, you register and start collecting.
The GST rule is separate and higher. The CRA says a small supplier doesn’t have to register while taxable supplies stay at $30,000 or less over four consecutive quarters. Go over $30,000 in one quarter and you must charge GST from that sale.
What does tax on a sale look like in BC?
Take a $2,000 sale of taxable goods. The GST and PST calculator shows $100 of GST at 5% and $140 of PST at 7%, so $240 of tax and a $2,240 total. Your books should show the $2,000 as revenue and the $240 as tax you owe, in two accounts for the two taxes. The same tool warns that some items are exempt from one tax and not the other, so check the item before you apply both.
Because BC has no single blended tax, your invoices should show GST and PST on separate lines. That makes each return a simple total of one column.
What if you run a BC company?
A BC company must keep adequate accounting records for each financial year and keep them for the prescribed period. The directors choose where. It also has to prepare financial statements for the latest completed year, following generally accepted accounting principles. We didn’t find the prescribed period on the pages we read, so six years is a sensible working figure, not a confirmed rule.
On income, the corporate tax calculator shows what a BC corporation with $300,000 of active business income pays for 2026. The result is $33,000, or 11.0%, made up of $27,000 federal and $6,000 provincial. An Ontario company in the same tool pays more, $35,088.
Self-employed people in BC can test their year with the self-employed tax calculator, which leaves out GST, PST and EI.
Mistakes worth avoiding
The usual one is a single sales tax account. When GST and PST land in one pile, the two returns are hard to reconcile. Another is treating five years as the whole answer. The PST period is five, but income tax needs six.
And if you want to destroy records early, you need written permission. That’s what the province says about PST records, so don’t just clear out the filing cabinet before the time is up.
More tools live in the sales tax hub.
Where the numbers come from
PST records, rates and the $10,000 limit come from the BC government’s small business PST guide. Company duties come from the Business Corporations Act summaries on BC Laws. Income tax and GST rules come from the CRA, all read in September 2026. Examples use this site’s 2026 calculators. This site has no connection with the CRA or any government.
