If you purchase bonds from secondary market platforms like bond bazaar, bonds india, wint wealth etc and hold them till maturity then 
Because this is redemption not sale of property. Does long term capital gains/short term capital gains apply (ltcg for holding more than 12 months or STCG for holding less than 12 months). 
I understand that ltcg / stcg gets applied if you have sold the bonds before the maturity date in the secondary market as there is sale of property so Either LTCG or STCG will be applied. 

The interest received would be taxed at slab rate. right?

Thanking you...
