hmm depends how much are they saying it will go up by and when?
This is a good question.
My RFL runs out at the end of March. Last year I had the renewal ready to renew on-line but left it till the day of the budget and of course when they announced the increase, it applies immediately, so by leaving it one day I got caught out. Will learn from this and will renew tomorrow morning.
Bit different for you, madgrip, as you will be renewing one month earlier so it depends how much it goes up, as to whether you will be better off.
On the other hand, having a March renewal is better for the future if they are going to put the tax up every year. Looking increasingly likely!
