Relaxation of additional fees permits filing company and LLP forms without extra fees until 31 July 2021, excluding charge forms. The waiver allows companies and LLPs to file forms due between 1 April and 31 May without additional fees if filed by 31 July; only normal fees apply, but charge forms CHG 1, CHG 4 and CHG 9 are excluded and remain subject to additional fees for late filing.
