Compliance with corporate and personal tax legislation is a key element in the success of government economic policy. Tax authorities at national, state and municipal levels are charged with both improving tax compliance and reducing the compliance burden on tax payers.

One very important component in tax compliance strategy is audit - whether it is audit by tax authorities or self-audit by taxpayers or their tax advisors. IDEA is used widely throughout the world for this purpose, improving the efficiency of tax auditors and thereby reducing the disruption of taxpayers' business activities, allowing corporations to avoid penalties and overpayments and offering professional accountants an additional service they can provide to their clients.
