Expert writing Tips
Best practice
Always use the grammatically correct form "based on this". While "base on this" might be understood, it's considered non-standard and can detract from your writing's credibility.
Common error
Avoid using the bare verb "base" when you need the past participle "based". The phrase should describe something that has been based, not something actively basing.
