Please correct me if I am wrong, and see question below:

• Tax deductible amount for LTF = 500,000bht or 15% of income, which ever is lower
• Tax deductible amount for RMF + Provident Fund = 500,000bht or 15% of income, which ever is lower

Potential total tax deduction can be 30% of income or 1 million baht, which ever is lower (LTF+RMF+Provident Fund)

Question:

How is income defined? Is it only off your base salary, or does it include all taxable income (e.g. annual bonus, commissions, etc)?

Much appreciated.

For your wages, it will be all the items that appear (gross) on your pay slip, so will include bonus as well as regular salary, etc. Your company should issue you with a payroll summary total and it should match that.
