Do i have to declare taxs for earnings from crowd funding platform such as seedin? If no, is there a cap for earnings before i have to declare them in my tax form?

I can't post the link but they use the term invest loosely.
U actually lend to sme so your returns are interest income and u have to report it.
In singapore just report it and if your total assessable income is less than 20k then no tax is paid.
