A tax penalty can apply when a person fails to notify HMRC that they are chargeable to tax.
At a glance
A new system of penalties applies to failures occurring on or after 1 April 2010. The new penalties will apply for the following taxes and accounting periods:
- Income Tax, Capital Gains Tax and Class 4 National Insurance contributions for the 2009-10 tax period
- Corporation Tax: accounting periods ending on or after 1 April 2009
- VAT: failures to notify liability to register which arises on or after 1 April 2010
- Other taxes and duties (not IHT and SDLT): failures where the obligation arises on or after 1 April 2010.
- Excluded from these provisions (they do not apply to):
Inheritance tax
Stamp Duty Land Tax
PAYE
There are also new rules for Class 2 National Insurance (for the self-employed).
These penalties are calculated along similar lines to penalties for errors.
Taxes & time limits
Time limits
| Tax | Event | Time limit |
| Self-employment and Class 4 NICS | Starting in business | 31 January following the end of the tax year |
| Capital gains tax | Obligation to give notice of liability | 31 January following the end of the tax year |
| Corporation tax | Notifying chargeability | 12 months from the end of the accounting period |
| VAT | Exceed VAT registration threshold over the past 12 months, or expects to turnover the whole VAT threshold in the next 30 days | 30 days |
Penalties
- No penalty is given as a result of failing to notify if no tax is due.
- If a person makes a full and unprompted disclosure within 12 months of first becoming liable for a failure to notify penalty, the penalty may be reduced to zero.
- There is no longer a fixed penalty for failure to notify for Class 2 NICS, see Penalties, Class 2 NICS, below.
Maximum penalties
The size of penalty depends on the amount of tax unpaid at the normal due date discounted according to the taxpayer's behaviour:
| Motivation governing failure to notify | Unprompted | Prompted |
| Not deliberate | 0% to 30% | 50% to 100% |
| Deliberate, but without concealment | 20% to 70% | 35% to 70% |
| Deliberate with concealment | 30% to 100% | 50% to 100% |
There is a minimum penalty of £300.
Reductions
- There is no penalty if the taxpayer has a reasonable excuse for the failure.
- No penalty is due unless there is tax or duty unpaid because of the failure.
- A penalty will be reduced if the offence has also attracted a late payment surcharge.
There are different rules for some Excise Duty registrations where the business is required to obtain approval before they can commence trading.
If HMRC is told about the taxable activity or liability, it will allow a reduction to a 30% penalty for disclosure. The reduction depends on whether the disclosure was prompted or unprompted.
Penalties can be reduced on the same basis as penalties for errors, according to the amount of effort that the taxpayer puts into cooperating with HMRC, for:
- Telling HMRC about it;
- Giving HMRC help and assistance in quantifying the loss;
- Allowing HMRC access to records.
