Kablenet poking fun at IR again... It will be 2008 before 1/2 of all Self Assessment tax payers complete their forms online if increases in usage continue at the same rate as the last year. I'll take that bet. Shall we go for 2004? By the end of the tax year 2004/5 (so January 2005), 1/2 of all tax payers will be completing their forms online. That would be around 3.8 to 4.5 million people, depending on which number you take. That compares nicely to the 50% of the country using the Internet that we have at present.
