We do it more closely than that: I logged onto the HMRC website this morning to discover I'd missed the deadline for submitting my self-assessment form... in spite of the email I'd received from them on Tuesday telling me that my submission had been accepted.were monitored so closely by HMRC
The HMRC systems apparently need 72 hours to get things sorted. On getting confirmation from their very helpful helpline that the submission had been accepted and my HMRC "account" was up to date, I was informed that I mey be receiving a letter through the post to tell me that I was late in submitting....
Here at the Chrons, we like to think we're a bit quicker (in opening and closing challenges and polls, and in having access to challenge statistics) than HMRC. And we don't hand out fines for people who don't enter or vote in time... though now I think about it....
