For UK employees without complex affairs, it's already done: my tax happens without any interaction, no digital conversion required. I spend £0 and about 60 seconds on my taxes every year. It's all arranged automatically between my employer and the tax authority. I just get a letter in the post every year telling me the calculation that I check is sane. My tax payments are deducted by my employer from my monthly pay.
