The Income Tax liability tables provide breakdowns of the number of income taxpayers and Income Tax liabilities by age and gender, marginal tax rate, income source and tax band, and by country and Government Office Region.
You can find all tables for previous years on the National Archives website. These tables are published twice yearly at schedules dictated by the release of new survey information for taxpayers and the publication of revised forecasts for the UK economy by the Office for Budget Responsibility.
8.9 billion hours spent complying with federal tax laws
What does this all mean for taxpayers? In short, that they're spending a lot of cumulative time complying with federal income tax laws. A recent estimation from the IRS suggested taxpayers would spend an aggregate of 8.9 billion hours complying with federal income taxes in 2016. That's nearly the equivalent of 13,000 lifetimes! In dollar terms, the IRS estimated an expense of $409 billion, including $99 billion in individual income tax compliance costs and $147 billion in business income tax compliance annually.
