Hey Dan, shoot me a DM, I'd be happy to jump on a call and shed some light on the rent data.

Instead of giving me excuses, brushing me off, ect ect, my taxes were done in 3 days.My tax liability went down by 10k with my deductions (now finally added) and my new CPA charged me $1300 for my business, personal and WALKING ME THROUGH THE WHOLE PROCESS.True Books charged me $6500 to get to this point (and wanted another $1500 for the final leg) to basically have me rack up fines, brush me off and gaslight me as if this is the norm.I'm writing this review as I wish someone had written it for me. 0/5 stars.The only thing True Books got done in a timely matter was the cashing of my checks.Sorry!
