(d) Advise Trent Limited of the consequences arising from the submission of the incorrect

正确答案：
(d) Default surcharge
Although the VAT return was submitted on time (i.e. within one month of the end of the tax period), part of the quarterly VAT
liability has not yet been paid. As a result this payment will be made late and a surcharge liability notice will be issued on
the company. The surcharge period will run from the date of the notice until the anniversary of the end of the period for which
the VAT was paid late (i.e. until 31 March 2007). During this period any further default will extend the surcharge period and
any further late payments of VAT will attract a surcharge penalty of 2% on the first occasion, rising to 15% for successive late
payments.
Mis-declaration penalty
As the return understates the VAT payable, a potential mis-declaration penalty arises. The amount understated exceeds 30%
of the sum of the true input tax and output tax, known as the gross amount of tax (GAT) ((30% of (87,500 + 55,000) +
40,000) = 54,750). There has, thus, been a significant understatement of the true VAT return liability, resulting in a penalty
rate of 15% of the VAT which would have been lost had the error not been discovered. However, where an under declaration
arises out of a true error i.e. there is no intention to evade tax involved, and it is voluntarily disclosed, then a mis-declaration
penalty is not normally imposed. Although the company is still within the ‘period of grace’ allowed by HMRC for the correction
of errors in the next following VAT return, it would be advisable for Trent Limited to notify HMRC of the error immediately, in
writing, unless it has a ‘reasonable excuse’ for the error having occurred.
Default interest
Default interest is chargeable when an assessment to VAT arises for an amount that has been under declared in a previous
period, whether as a result of voluntary disclosure or as identified by HMRC. Interest is charged on a daily basis from the
date the under declaration should have been declared (i.e. 1 May 2006) to the date shown on the notice of assessment or
notice of voluntary disclosure. As given the size of the error the de minimis relief for voluntarily declared errors of less than
￡2,000 is not applicable, the only way for Trent Limited to minimise the interest charge is by means of early disclosure and
payment of the additional VAT due.
