Do I need a separate bank account for my business

For a sole proprietor it is not strictly required, but it is one of the highest-value habits in bookkeeping. If your business is incorporated, it is not optional: a corporation is a separate legal entity and its money has to be kept separate from your own.

Why it matters even when it is not required. When business and personal spending run through one account, every reconciliation turns into a sorting exercise, every expense needs a second look to decide whether it counts, and the line between an owner draw and a real cost blurs. A dedicated account makes the bank feed match the business, so reconciling is ticking off transactions rather than untangling them, and your expense total is trustworthy without a mental audit.

It also protects you at year end. Clean, separate records are exactly what your accountant needs to prepare your return, without billing you to sort personal coffees out of a business statement first.

Where TALISK_HQ fits. TALISK_HQ works either way, but it shines with a dedicated account: connect it and the whole business feed reconciles against one place. When personal money does pay for a business cost, there is a proper way to record that rather than mixing the accounts, covered in what if I paid for something with personal money.
