Do I need to file a self assessement just for Gilt coupon and ETF dividend?

Hello, My only income is bank interest, Gilt coupon, and ETF dividend . My Gilt and ETF (a Ireland domicile ETF, traded on London stock exchange) is held in a UK broker). The total is less than £10,000. I've checked the gov link "Check if you need to send a Self Assessment tax return". But I'm not exactly sure. Do I need to file a self assesment just because I've Gilt coupon and ETF dividend? If yes, I understand Gilt coupon is reported in SA101? Where do I put in the ETF dividend? in SA100 under "Interest and dividends from UK banks and building societies"?

Hi,
All ETFs you dispose of, are subject to Capital Gains Tax. The type of ETF, determines the how it is taxed. Equities are taxed as dividends and should be declated in box 5, other dividends, on page TR3 of SA100.
Bonds are taxed as Income Tax and should be declared in box 3 of page Ai1 on SA101.  
Commodities are not subject to Income Tax or dividend tax.
Thank you.
