Legalesign Advanced Electronic Signature
Starting 6 April 2025, tax advisers must use Advanced Electronic Signatures (AES) for client authorisations, especially when submitting Income Tax or PAYE repayment claims. Our AES and PDF certification ensures the integrity and authenticity of documents and its signatures. AES must be uniquely linked to the signatory, capable of identifying them, and be created using data under their sole control, ensuring any subsequent changes are detectable.
