## Separate the money first
Use a dedicated account or clear labels. Platform fees and refunds are not “net profit.” Rough Side-hustle quarterly tax estimate calculator and Self-employment tax beat a surprise bill. Rules in Canada vary — educational only.
## VAT/GST thresholds
Some hustles hit registration thresholds earlier than you think. Peek at VAT GST and Invoice with tax before you scale ads. When unsure, official guidance for Canada beats a blog post.
