Kudos to HMRC for forgetting to tell people that it had changed its bank account details, for firms which pay tax using IBAN, in February.
Can you guess what happened next children?
Yes, that's right, tens of millions of pounds in VAT and corporation tax has not been paid.
The Telegraph reports that large tax payments from a number of businesses have bounced and remain uncollected.
However, no problem as far as HMRC is concerned.
It has levied the hapless firms with penalty notices and, even better, has still not told them how to pay what they owe!
A senior executive within the tax department of a listed multinational company, who asked not to be named, told the Telegraph that the first he knew about his £6m VAT instalment being rejected was when the firm received a late payment notice.
“Our payment is now nearly a month overdue and we have still not received instruction from HMRC on how to pay. The way they have handled it is so shambolic, I would not be surprised if this is a much wider issue.
These cases may just be the tip of the iceberg as although there was some advance notice in a couple of HMRC publications, those notices did not include the vital IBAN number businesses need to make payments."
