Abstract
${\cal O}(\alpha)$ QED radiative corrections to neutral current deep inelastic production of heavy quarks are calculated in the leading log approximation and compared with the corresponding corrections assuming a massless charm parton. Besides the inclusive case, corrections to the semi-inclusive $d^3\sigma/dx dy dz$ and the effect of z-cuts are studied. In the latter case, the massless corrections differ from the correct massive radiative corrections to deep inelastic heavy quark production by about $40 \%$ - $10 \%$ for $0.2\lesssim z \lesssim 0.5$ .
