Deduction for authors' royalty income allows a capped allowance subject to repatriation and certification conditions.

Deduction for royalty and copyright income of resident individual authors permits an allowance equal to the income or a specified monetary cap, whichever is less, for assignments, grants or royalties relating to books other than text books; non lump sum receipts are adjusted by ignoring the portion exceeding fifteen percent of the value of books sold before expenses; foreign income is included only if repatriated in convertible foreign exchange within six months (or extended by competent authority); prescribed certificates from the payer and, for foreign income, from a prescribed authority are required; the deduction is exclusive of other Act provisions.
