Welcome to the axeman or right taxman! your pin number is the only identifier and those in authority know it.you only have to print the registration certificate from the site as proof,as with other e-docs no signature is appended.

Circumstance does not make the man; it reveals him to himself............... 'James Allen'

@ The Real Shaft: Those instructions by flipthecoin are true. The Taxpayer Registration Certificate is e-generated and you can print it from any internet browser. It has a document number and a remark at the bottom that reads 'This certificate is computer generated and therefore not signed. It is valid certificate issued under the authority of KRA.' Taxpayer data included in the certificate include Tax Obligation,Contact information,and Activity. Looks like KRA is embracing technology in its operations. Just printed mine this morning and glad i din't have to endure those long queues at Times Towers.
