We consider stratifying ideals of finite dimensional algebras in relationwith Morita contexts. A Morita context is an algebra built on a data consistingof two algebras, two bimodules and two morphisms. For a strongly stratifyingMorita context - or equivalently for a strongly stratifying ideal - we showthat Han's conjecture holds if and only if it holds for the diagonalsubalgebra. The main tool is the Jacobi-Zariski long exact sequence. One of themain consequences is that Han's conjecture holds for an algebra admitting astrongly (co-)stratifying chain whose steps verify Han's conjecture.  If Han's conjecture is true for local algebras and an algebra admits aprimitive strongly (co-)stratifying chain, then Han's conjecture holds for it.
