The Commissioner may require an agent, subagent, collector or applicant for a registration certificate to deposit with the Minister a bond by way of cash or other security in such amounts as may be determined by the Commissioner, which shall not in any case be greater than an amount equal to six times the amount of the tax estimated by the Commissioner to be the amount normally collected by the applicant or collector each month in compliance with this Act or the regulations. In making an assessment the Commissioner shall not consider a period or periods of time greater than four years prior to the date of commencement of the inspection, audit or examination of the books of account, records or documents, unless the Commissioner deems the person did not exercise the degree of care, diligence and skill to prevent an offence that a reasonably prudent person would exercise in comparable circumstances, or if there is evidence that the person has committed fraud, and the results may be applied over the period or any part of the period. Where a person is convicted for a contravention of the Act and a previous conviction for a contravention established, the person convicted may, in addition to the pecuniary penalty, be imprisoned for a term of not more than six months. Upon the conviction of a person who holds a driver's licence, vehicle permit or certificate of registration issued pursuant to the Motor Vehicle Act, the Registrar of Motor Vehicles shall suspend the licence, permit or certificate of registration of the vehicle in respect of which the violation was committed for a period of thirty days for a first conviction, ninety days for a second conviction and six months for any subsequent conviction. Upon the conviction of a person who has been issued a permit of any kind pursuant to Part I of the Act, the Commissioner shall suspend any such permit in so far as it relates to premises, facilities, vehicles or an activity in relation to which the violation occurred for a period of sixty days for a first conviction, six months for a second conviction and one year for any subsequent conviction.
Interest is compounded monthly, with the rate changing quarterly.
Interest on refunds is calculated from the date the tax was remitted until the refund is paid or applied to a vendor's account, but only on tax paid in error, or a paid assessment that was later reversed. Interest on penalty assessments and any unpaid tax is calculated from the date when the default first occurred until the assessment is paid. Fuel is coloured using TEF Red FF 20. Commercial farmers, fishermen, lumbermen, manufacturers and others using fuel for exempt purposes, must use coloured fuel, or pay the tax if clear fuel is used. If tax is paid, they may apply for a refund.
