Open a separate bank account for creator money so business and personal never mix, that one move makes everything else easy. Log every payment as it lands, cash, affiliate and gifted product at fair market value. Then save receipts for anything you use to create: gear, software, a share of your phone and internet, props, a home office. Those are write-offs that cut your taxable income. A simple spreadsheet or an app does the job. General info, not tax advice.
Separate the money first
One dedicated account for creator income and spend. Mixing is the root of tax chaos.
Log income as it lands
Every payment, including gifted product at fair value. Catching up in April is misery.
Save every receipt
Gear, software, phone and internet share, props, home office. They lower your tax.
Pick one system
A spreadsheet or an app, it does not matter. What matters is you actually use it.
