Self assessment can drive growth in 2013

Many tax jurisdictions now rely on self-assessment as the major means of tax collection; it has become a tax modern administration trend. Indeed it is now a measure of how up-to-date a tax authority is.
By way of definition, it is a tax regime whereby the taxpayer is granted the right, by law, to compute his own tax liability, pays the tax due (at a designated bank, as is the case in Nigeria) and produces evidence of tax paid to the Tax Office, at the time of filing tax returns, on due date.
On the part of the tax authority, it accepts the tax returns as filed, subject to completeness, and carry out audit in due course. Very much unlike an administrative assessment were the tax authority raises an assessment where a taxpayer has failed to file returns and pay taxes due on or before the due date or where there is an understatement of tax in the returns filed.
With the taxpayer’s assumption of the role of assessing self, an obligation arises for the tax authority to ensure that the taxpayer understands the procedures involved in tax administration and how to compute tax liabilities and complete tax returns (if the option is self-service).
In addition to taxpayer enablement, it is the responsibility of the tax authority to ensure compliance with all tax administration processes especially accuracy of declarations made and the timeliness of tax returns.
In Nigeria, the Federal Inland Revenue Service (FIRS) introduced the self assessment regime in 1992 following the enactment of the appropriate law in 1991. The FIRS Board, in exercise of the powers conferred on it by Section 61 of the Federal Inland Revenue Service (Establishment) Act 2007, with the approval of the Minister of Finance gazetted a Regulation dated 19 December 2011 modifying the processes and procedures for self assessment returns. The Regulations cover tax returns under the Companies Income Tax Act (CITA), Education Tax Act (ETA), Petroleum Profit Tax Act (PPTA), Personal Income Tax Act (PITA), National Information Technology Development Act (NITDA), and Value Added Tax Act (VATA).
However the method has not been as successful as envisaged. Many will argue that risk based audit which is a major feature of self assessment has not been not been fully optimized. Risk based audit assist in risk identification, analysis, assessment, evaluation and prioritization, with the pre-determined risk ratios drawn from a risk framework, every tax return is subjected to risk analysis and assessment.
This in itself is a departure from the government assessment of best of judgement where time and capacity impeded 100% audit. Under risk based audit, resources are applied to areas of risk in the order of the weight attached.
Fundamentally, automation of the filing process will encourage taxpayers to file their returns independently instead of using the outdated administrative assessment or best of judgement. In this regard the Integrated Tax Administration System (ITAS) project being undertaken by the FIRS will play a key role. FIRS will need to fully exploit technology to endear efficiency in the process of Self-Assessment.
Also for the benefits of Self Assessment to be fully optimized a more robust mechanism whereby compliance checks are conducted through risk based case selection for audit; In which case, all Tax returns have equal chance of being selected for audit.
This approach is a demonstration of transparency in tax administration and is expected to encourage self disclosure and clearer disclosure benchmarks also need be to put in place. Another key driver will be to have a strong Audit and Compliance department that can ensure the validity of disclosure.
Using the Australian Tax Office (ATO) as a global case study of the self-assessment system, the claims a taxpayer makes in their tax return are accepted by the (ATO), usually without adjustment, and an assessment notice is issued. Even though we may initially accept the tax return, the return may still be subject to further review.
To ensure the integrity of the tax system, the law provides the ATO with a period where it may review a return (and make sure all income has been included) and may increase or decrease the amount of tax payable.
The ATO has powers to amend an assessment up to two years (or four years for taxpayers with more complex tax affairs) after tax become due and payable under the assessment. Where anti-avoidance provisions apply, the period is four years. Where the avoidance is due to fraud or evasion, there is no time limit on amending the assessment. If the FIRS can push such laws through it will certainly ensure and endear voluntary and honest filing of returns.
Generally speaking, the adoption of self assessment principles reflects a desire to move away from in-house administrative assessment procedures in favour of more comprehensive and targeted approaches to providing help and assistance to taxpayers, and to the systemic verification of reported tax liabilities through risk-based desk and field audits and computerized matching of income reports.
In countries where self-assessment has been adopted, it has generally been initiated with the objective of improving overall compliance with the laws and increasing operational efficiency by collection of tax revenue on time, streamlining the system of returns processing and reducing the incidence of disputed assessments.
Self-assessment ultimately reduces administrative costs for tax authorities and aided by modern technology, most economies have adopted the principle to drive down cost and ensure timeliness in filling return and Nigeria can benefit from this trending revenue collection system.
Self-assessment also reduces the discretionary powers of tax officials and reduces opportunities for corruption. However, self-assessment needs to be properly regulated and implemented, with transparent rules, an automated reporting process, and penalties for noncompliance and risk based assessment procedures for audit procedures.
Also, the FIRS need to embark on media sensitization campaigns to achieve a change in behaviour of both taxpayers and tax officials in favour of a taxpaying culture through strict application of sanctions. This way non-compliance will be dealt with timely and will be deterred. Internal and external stakeholders’ engagements will key in implementation and success of Self-Assessment regime.
