Where CDF offer is made 30 June 2014 onwards: managing the detailed disclosure process: indirect tax assessments
The prevailing time limit for VAT assessments is 12 months after evidence of fact becomes available to HMRC. Where you have been provided with any information relating to indirect tax issues you must be mindful of the time limits for raising your assessments.
The time limits for issuing indirect tax assessments are different from the rules for issuing direct tax assessments. Even where you have clear deliberate conduct and a 20 year overall limit, you need to be very careful that you are not excluded from assessing by other, shorter time limits.
The periods for which assessments can be raised is determined by the nature of the irregularities. Full details are provided within the VAT Assessments and Error Correction Manual (VAEC).
It is vital to keep the one year evidence of facts rule in clear view and regularly assess whether or not you have been given enough information to issue the assessments.
You must not assume that this will not be an issue later in your investigation. You might find that the ‘evidence of facts’ provided within the Outline Disclosure is sufficient to justify making assessments. If that is the case then you should issue the assessments as soon as possible and certainly within 12 months. Under no circumstances should you delay making assessments on the assumption that you will soon receive more information which will enable you to raise a better assessment. If that information never comes in, you may find yourself time barred from using what you have and the tax will be lost.
Note: A clear finding of fraud does not allow you to override the 12 months evidence of facts rule.
If you are in any doubt about the correct procedure you must make sure that you seek the appropriate advice at the earliest opportunity, from Tax Advice and Administration - TAA.
