defer self assessment payment due to covid19
i have a self-assessment payment of approx. £9k coming due on july 31st, acccording to my hmrc at-a-glance webpage, that is, but the letter i recently received says the 9k is only due by 31st january and there will be no penalty or extra interest incurred by not paying now.
it looks like a bit of a no-brainer in that i could leave that £9k in my ns&i income bonds account and earn about £50 or so in extra interest by deferring payment until next january but is it really that simple? i have read through the letter and that hmrc webpage here:
sevral times and i cannot see any catch, but since when has hmrc ever given anyone anything for free?
is there some hidden catch here i cannot see?
