Hi RainyDay
NERI's FAQ does not deal with any of the substantial criticisms which I have made
1) The bottom decile does not pay 30% of its income in taxes. It gets 85% of its income from the Exchequer, so it has a massive negative tax rate.
2) There is no proper explanation of why their expenditure for the bottom decile is twice their income.
3) By and large, there is no VAT or indirect taxes on the necessities of life - basic foodstuffs, accommodation, and public transport
4) The 23% VAT rate and high excise duties apply to the luxuries - Cigarettes, petrol and booze.
5) Direct taxation is not levied on households - individuals and married couples are charged tax and the effective tax rate on individuals with an income of €160,000 is far higher than 24%
6) The data is based on the 2009/2010 period. Effective Tax Rates are much higher now for three reasons. They do not appear to have made any adjustment for the USC which was introduced in 2011 and adds an additional 6% points to the income of someone earning €160,000. Nor do they appear to have made any adjustment for the phasing out of legacy property tax reliefs will have also increased the Effective Tax Rate. I think that the introduction of Minimum Effective Rates of Tax will also have raised the Effective Rates since 2009/2010.
The policy implications are significant
Last year, NERI called for the Effective Rate of Tax on the top earners to be raised by 1.5% to 25%(?) Say the Minister for Finance announced in the coming Budget that he was abolishing all tax personal credits, allowances, pension deductions, medical expenses, nursing home fees, carers' allowances etc for those earning over €100,000 and he was going to charge a simple 27% of all their income instead of the mixture of income tax, USC and PRSI. This is a far higher tax rate that NERI is proposing. The high earners would be thrilled.
The direct taxation system in Ireland is not fair. Tax evasion is commonplace among low earners and high earners. Some people still have exempt income - artists, those with forestry income and, some who still benefit from the historical property tax incentives. High direct taxes on luxuries helps to redress the balance in a very small way.
The source of the data
The data is derived from the 2009/2010 Household Budget Survey not from the actual tax rates (where the marginal rate is 55%) or the Revenue Statistical Reports.
The purpose of the Household Budget Survey is to collect information for inflation calculations. In this survey, 5,000 people keep a record of their expenditure and their income and their tax payments for a two week period. NERI extrapolates this to a full year to work out the Effective Rates of Tax.
Direct taxation - income tax, prsi and USC
Direct taxation in Ireland is not based on households or on what decile of income you are in.
Individuals and married couples are the unit of taxation and the tax is based on their income.
NERI claims that a household with an average income of €159,000 pays 24% in direct taxes. A self-employed individual earning €160,000 who does not take any advantage of tax relief on pension contributions, etc, pays an effective tax rate of 47%. A couple earning €160,000 between them pays 40%. In 2011, according to the Revenue data, a single person earning between €150k and €200k paid 31% in income tax alone on their gross income. Some income such as child benefit and maternity benefit is not taxed, so you can argue that the Effective Rate of Income Tax was lower. I am trying to clarify with the Revenue the impact of pension contributions on the calculation of gross income. But let's reduce the 31% income tax to 27%. Now add 11% for USC and PRSI, so the effective rate of tax is 38%.
I am working on a full paper on this.
Indirect Taxes
The bottom decile has reported expenditure twice its reported income. I imagine that this is due to the manner in which the data is collected. It's self reported data from a sample of 5,000 households over a two week period.
At the very least, NERI should highlight this in its summaries and its press comments. I was not aware of this until Séamus Coffey pointed it out.
