I want to start paying my taxes, but...

I'm currently working as a VA for almost 4 years na. Tho most of the jobs I had were short term projects lang, hindi na ako nag comply sa BIR to pay taxes.

But I decided to pay my taxes na, kasi I've heard na most of the times need ito to apply for visa?

Problem is, I have no idea on the step by step process for filing sa BIR. I'm currently earning 25k monthly on my job, pasok ba to sa tax bracket ng BIR. (EDIT: Magwa-one year pa lang ako sa current employer.)

Insights are greatly appreciated.

EDIT:

APPLYING FOR A VISA IS NOT MY SOLE REASON kung bakit ako magsstart mag bayad ng TAX. I've read sa ibang threads na they're (VA, FREELANCERS) paying taxes kasi isa yun sa pre requisite in applying for a VISA, kaya ayun yung nalagay ko.
