I have no ITR but I have 2307 (Certificate of Credible Tax Witheld At Source), will it be accepted?

I've been working in a government agency here in the Philippines for 2 and half years as Contractual (no employee-employer relationship). They cannot issue me an ITR, only 2307. I can get a certificate of employment from my agency though. Will I still be able to get a visa even without the ITR (2316)? Use the 2307 instead of it? Thank you.
