It's best to think of 'paying yourself' as an allowance. When operating as a sole trader, your business income and account balance is already your money. You and your business are one and the same.

When taking an allowance, make sure you have enough funds to continue running the business sustainably. Then take only what your business can afford.

Be sure not to classify payments to yourself as business transactions in Earnr. Any transfers of funds from your account to another of yours is neither income nor expense for your business. Those payments have no impact on your profits or any potential tax bill. That way we won't include them in your tax return.
