It seems for English translations, we can pick between:
A: R. Shamasastry (1915),
B: R. P. Kangle (1969),
C: L.N. Rangarajan (1992)
D: Patrick Olivelle (2012) [late edit. looks incomplete]
From my initial reviews of A and B, A misrepresents the original text vastly and B translates the original text using the words that are actually written in it. (I find that an important measure for a translation). Reviews of C indicate that it is incomplete and out of order. Therefore, B seems like the only potentially true translation. You can find it on Amazon[0], Google Books[1], and Digital Library of India[3][4][5].

METHODOLOGICAL PUZZLES AND METHODOLOGICAL/THEORETICAL APPROACHES
The Arthaśāstra's authoritative translations into English (R.P. Kangle) and German
(J.J. Meyer) were made by Indologists. Also, the secondary literature on the work
comes almost exclusively from the Indologists. 6 The Indological perspective is
focused on Sanskrit philology, but with respect to specifically political issues,
Indologists are (probably, inevitably so) 'semantic generalists'. Sanskrit philology has
made the Arthaśāstra accessible to social science, but the philological meticulousness
of Indologists cannot substitute political science terminology – which is the
prerequisite for an adequate understanding of Kauṭilyan ideas. The problematic is not
merely one of proper translation in terms of political science terminology, but brings
up the issue of interpretation in the sense of adequate reconstruction of (latent) ideas
or 'complexes of meaning' in the Arthaśāstra and the 'transposition' of such ideas into
modern categories.
