Can I tag personal spends so they stay out of business reports?

Yes. Mark personal transactions as Personal in your bank feed (either individually or in bulk) and they stay out of your P&L, Balance Sheet, and tax calculations.

Personal transactions are still visible in the bank feed - toggle the Hide personal filter to show or hide them.

This is especially useful for sole traders running personal and business through the same account, or for company directors who occasionally use the company card for personal items.
