HIGH MARGINAL DEDUCTION RATES
57. The Treasury defines the poverty trap as occurring
"when those in work have limited incentives to move up the
earnings ladder because it may leave them little better off".[214]
Marginal deduction rates are used to measure how far people's
incentives to increase their income are being reduced. For instance,
a marginal deduction rate of 65% means that, for every one pound
of additional income earned, 65 pence of that extra pound is taken
away, either by taxes or a reduction in benefits. Chart 1 shows
how the Government's policy mix has affected the distribution
of marginal deduction rates over time.
Chart 1: Marginal deduction rates and
the poverty trap
Sources: Budget
2002, p 79, Table 4.4; Budget 2003, p 91, Table 4.2;
Budget 2004, p 97, Table 4.2; Budget 2005, p 98,
Table 4.2; Budget 2006, p 94, Table 4.2; Budget 2007,
p 102, Table 4.2; Budget 2008, p 62, Table 4.2
As can be seen from Chart 1, while the Government
has been successful at moving people from the highest marginal
deduction rates above 70%, the number of people caught by a marginal
deduction rate of between 60% and 70% has increasedby around
200,000 between the tax years 2007-08 and 2008-09.
58. The Treasury stated in the Budget that that this
increase was "primarily due to the introduction of tax credits,
which has extended financial support so that far more families
benefit, including low-income working people without children".[215]
Mr John Whiting of PricewaterhouseCoopers explained that changes
within the Government's policy mix had also increased the number
of people caught by marginal deduction rates at this level:
as the tax credits have become more generous
that naturally takes this level at which the claw back starts
to affect people up higher. If we go back two or three years when
tax credits were first introduced we would be looking at people
on incomes of £12,000 to £14,000 and as the credits
have become more generous that has made them more available further
up the income scale but it has meant more people being subject
to claw back over a wider income band than used to be the case.[216]
However, Mr Whiting acknowledged that such high marginal
deduction rates might be the consequence of the Government trying
to achieve its social policy goals. He told us that "It is
one of the imponderables
that as soon as you give benefits
and then say, 'We want to withdraw them', you are facing people
with a significant taper".[217]
59. When asked why around 200,000 extra people now
faced marginal deduction rates between 60% and 70%, Treasury officials
told us that:
The main reason for that is partly, indeed primarily,
as a result of the 2007 Budget measure that introduced extra help
through tax credits from 2008. That brought more people into tax
credits, the result being that more people then faced higher marginal
deduction rates.[218]
Treasury officials also acknowledged the choice faced
by Government when deciding how to distribute benefits:
There is not a perfect answer. You could go for universal
support, as, of course, he has done with child benefit, but in
that situation you are not targeting the public resource on those
who need it most and that leads inevitably to one of two consequences:
either you have to spend more to provide that level of support
for the poorest or on the other hand you support the poorest less,
so that is universal support. You could equally go for a very
steep cliff edge with very high marginal deduction rates which
would leave a smaller group of people affected by high marginal
deduction rates, but then you are leaving those people with a
massive disincentive, or, which is what the Government has done,
you can focus resource on the more needy and then gradually withdraw
that through a taper.[219]
The Chancellor of the Exchequer defended the decisions
made on tax credits, and the consequences that this had had on
the marginal deduction rates faced by some people. He explained
that:
When you decide you want to increase people's incomes
through the tax credit system, the down side is that when they
come off it there might be a disincentive there. You try and avoid
that by a taper but of course the taper will then take you further
up the income scale. There are ways in which you can mitigate
that but I would not want to get myself into a situation where
frankly I did not increase the incomes of people if I thought
that was the right thing to do.[220]
60. The
increase in the number of people facing marginal deduction rates
of between 60% and 70% is a direct consequence of decisions made
by Government as to how the tax and benefit system will work.
We acknowledge that such decisions are finely balanced between
the overall cost of a benefit, and the rate at which it is withdrawn.
We recommend that the Government undertake further research into
how the design of the tax credit system, in conjunction with the
overall tax and benefit system, is enhancing or impeding progress
on the Government's welfare to work objectives, and report on
such work in the 2008 Pre-Budget Report. We recommend that, as
a basic principle, the Government ensure that high marginal deduction
rates are limited wherever possible, and we will continue to keep
this matter under review.
TAX CREDIT TAKE-UP RATES
61. High marginal deduction rates are faced by those
who are already part of the tax credit and benefit system, but
not all those eligible take up the tax credits owed to them. The
importance of the need for higher levels of tax credit take up
were highlighted when we discussed the reforms announced in the
2007 Budget, which included the abolition of the 10 pence starting
rate of income tax, and a reduction in the basic rate of income
tax from 22 pence to 20 pence from April 2008.[221]
As a result of these reforms, some low-income workers may have
been potentially disadvantaged because the loss of the 10% starting
rate of income tax was not outweighed by the gain from an overall
lower basic rate of income tax. The Treasury provided the following
evidence as to who might lose as a result of the changes in Budget
2007, and how those losses may be mitigated:
Estimates are that 0.8m single earners with income
under £18,500 will see their income decrease by around £1.45
a week on average. The reforms overall, however, are of particular
benefit to low income households. The reforms will lift around
200,000 children out of poverty, and analysis of the reforms by
the Institute for Fiscal Studies showed the greatest gains are
for households in the poorest two deciles. The maximum amount
any single individual could be worse off by is £232 per year
(£4.46 per week) about 3% of net income. This loss would
be completely offset by increases in Working Tax Credits for those
eligible to claim. For those not eligible for [Working Tax Credits]
it is possible that households around or under the level of income
achieving the maximum loss could be receiving Housing and/or Council
Tax Benefits and could therefore have up to 85% of this loss offset
by increases in HB/CTB. For households that are worse off, the
average loss is about £2 per week.[222]
The Chancellor of the Exchequer acknowledged that
there were some sections of society that would be affected by
the loss of the 10 pence starting rate of income tax:
There is a particular group of people, mainly women
between the age of 60 and 65, who would have been paying the 10p
rate who, if you look at where their incomes have come from in
the last ten years, [are] better off than they were. Yes, it would
affect them.[223]
The Chancellor of the Exchequer was also keen to
point out that "We have tried to help wherever we can through
the tax credit. I have mentioned the winter fuel payment and for
a lot of people their incomes will have gone up." He also
to stated that overall "the reduction to 20 pence will benefit
very substantial numbers of people".[224]
Those most
affected by the abolition of the 10 pence rate of income tax appear
to be those below the age of 65 with an income under £18,500
who are in childless households. The effect is greatest on those
households where no individual is above the age of 60 because
the household does not then benefit from the higher winter fuel
allowance. We accept that there are benefits in tax simplification
and that there are merits to focus on both the needs of children
and motivation to work. However, the group of main losers from
the abolition of the 10 pence rate of income tax seem an unreasonable
target for raising additional tax revenues to fund these and other
initiatives.
62. Despite tax credits being identified as one of
the ways of mitigating the loss of the 10 pence starting rate
of income tax, as Treasury officials acknowledged, there has been
a continuing problem of low take-up rates of working tax credits.[225]
As we noted last year, the problem of low take-up rates is especially
acute among families without children, where the central estimate
of the take-up rate of working tax credits was 22% for the financial
year 2005-06.[226]
Treasury officials pointed out that
take-up of the working tax credit, which I agree
has not been as good as we would have liked, is increasing. That
is also an important reality to bear in mind, and steps are being
taken to draw the attention of people who can claim that tax credit
to the fact that it is available, and that is having some success.
More people are claiming the working tax credit.[227]
The Chancellor of the Exchequer also acknowledged
that "There are particular groups who would be eligible for
the working tax credit who are not taking it up and that is something
that we need to do something about".[228]
He reiterated his desire to see further action, telling us that
"where take-up is insufficient, particularly with people
without children, I would like to see us do more".[229]
We are
concerned by the poor take-up
rate of working tax credit among eligible families without children,
especially given that working tax credits are intended to mitigate
for low-income households the effect of the removal of the 10
pence starting rate of income tax. We expect the Treasury and
HM Revenue & Customs to galvanise their efforts in this area
in coming months and years. We recommend that the Government report
regularly in Budgets and Pre-Budget
Reports, starting with the 2008 Pre-Budget
Report, on progress in increasing the take-up
rates of working tax credits for those sections of society with
particularly low take-up
rates. We further recommend that the Treasury commission research
into whether the withdrawal of the 10 pence income tax band and
high marginal deduction rates are creating disincentives that
could frustrate the Government's welfare to work objectives.
