I'm still receiving few messages due to my comment from other sub but can't reply na sa paisa-isa so thought of posting instead for wider audience.

Here's what must be done to request for RDO transfer. Usually part of pre-employment requirements sa new job and ang registered RDO mo is business place ng former company.

Recommended as per BIR personnel is transfer to RDO ng permanent residence mo so no need to request everytime you change job.

1. Download BIR form 1905 sa google.
2. Fill up those with check marks only as attached sample form in here.
3. Email your current RDO (kuhanin po sa website ang email add) attaching the BIR form 1905 and scanned copies of 2 valid IDs.

FAQs: What's the TAT? Got the confirmation and completion slip from RDO 049 within the day.

What to put on Title and Position of Signatory? Nilagay ko lang is Taxpayer.

I don't work for the bureau so it's still best to confirm with them for other details. This is solely based on my personal experience when I successfully did my transfer. Thank you.
