Re: "Openreach owner BT will pay minimal tax in the coming years"
That's not how it works. Corporation Tax is due to increase. That give companies an incentive to delay capital spending as they might as well pay tax at the current lower rate, then spend to reduce taxes when the higher rate kicks in. By introducing the 'super deduction' the government has reduced the incentive to wait.
In the end it's a win-win. Companies spend sooner which boosts the economy now which is when we really need it.
I can't really benefit from the 'super deduction'. Instead, I'm paying little into my pension this year to max out the CT payment. When the rate goes up, I'll make pension payments to keep my little company in the 19% band for CT.
