Taxing wealth and income fairly

Same money, different ways of getting it

There are three main ways money arrives in someone's pocket.

Not all of these forms of income are taxed the same. For example, National Insurance is only applied to earnings. [1]

But, should how you get your money affect how much tax you pay?

There are arguments for and against this approach.

Why some say it's fair

• The money has often been taxed already. Dividends are paid out of company profits that have already been taxed, and the money people invest usually came from earnings that were taxed too.
• Investing involves risk. People can lose money on shares or property, and lower taxes on gains encourage them to invest in businesses that create jobs and economic growth.
• Some gains are just inflation. If a share's price rises only because prices in general have risen, the owner isn't better off in real terms, but they can still be taxed on the gain. [5]

Why others say it's unfair

• A pound is a pound. Someone working for their money can pay a higher rate than someone who receives the same amount from owning things.
• The benefit goes mostly to the wealthy. Most shares and property are owned by people who are already well off, so lower rates on this kind of income mainly help them.
• It encourages tax games. Some company owners pay themselves in dividends rather than salary, purely to pay less tax.

Income is a flow. Wealth is owned.

This leads to an important distinction. Taxing income from wealth (such as rent or dividends) is not the same as taxing wealth itself (the value of what someone owns).

Getting richer and receiving taxable income are two different things. For the very wealthiest, most of their growth in wealth often comes from rising asset values rather than income.

How is it taxed today?

A quick tour of the main UK taxes on income and wealth:

• Earnings are taxed through income tax and National Insurance.
• Dividends, interest and rent are taxed as income, but dividends and savings interest have their own rates and allowances, and none of them pay National Insurance.
• Gains from selling assets are taxed through capital gains tax. Your main home is usually exempt, and gains on assets held until death are wiped out for capital gains purposes. [6]
• Property is taxed through council tax and stamp duty. In England and Scotland, council tax bands are still based on property values from 1991. [7]
• Inheritances may be taxed through inheritance tax, although fewer than one in 20 estates pay any. [8]
• Pensions and ISAs let people save or invest with tax relief or tax-free growth, up to set limits.

There is no tax on wealth itself in the UK.

What would a fair system look like?

"Fair" means different things to different people. These four principles give a way to judge any system or proposal:

• Ability to pay: should people with more resources contribute more?
• Consistency: should similar amounts of money be taxed similarly, however they were received?
• Protection: how should the system treat modest savings, pensions, and people with valuable assets but little cash?
• Practicality: can the tax be valued, collected and enforced without too much complexity?

These principles often pull against each other. A tax that scores well on consistency might be hard to collect. One that protects modest savers might create loopholes for the wealthy.

What could change?

Four broad approaches come up most often in the debate.

Whichever is chosen, success depends on strong enforcement, international information sharing and fewer loopholes. Past reforms have often failed for want of these.

1. Tax gains and investment income more like earnings

   The idea

   Bring the tax on dividends, rent and capital gains closer to the tax on wages. [5]

   Why it might help

   The source of someone's money would matter less, making the system more consistent.

   The hard question

   How should inflation, losses and the risks of investing be treated, and would people invest less?

2. Tax very large fortunes

   The idea

   An annual wealth tax above a high threshold.

   Why it might help

   It reaches wealth that grows without producing much taxable income.

   The hard question

   What counts, how is it valued, and what happens when someone can't pay in cash? [9] Our Extreme Wealth Line explainer looks at this in more detail.

3. Reform taxes on land and property

   The idea

   Replace or update council tax and stamp duty, perhaps with a tax based on current property or land values. [5]

   Why it might help

   Bills would reflect what property is actually worth today, and land can't be moved abroad.

   The hard question

   How do you protect people with low incomes living in homes that have risen sharply in value?

4. Reform inheritance tax

   The idea

   Change who pays and how, for example by taxing what each person receives over their lifetime rather than the size of the estate left behind. [5]

   Why it might help

   It could encourage wealth to be spread more widely and close gaps used by the wealthiest estates.

   The hard question

   What allowances, exemptions and payment arrangements would be fair, particularly for family homes, farms and businesses?

Enforcement is the key

Lack of enforcement and enforcement mechanisms are frequently cited as the reason for failed tax reforms. Whatever approach is taken, effective enforcement is the key to its success.

The questions any proposal must answer

The answers depend on the details of each proposal, but these are typical considerations when drawing up plans for tax reform.

1. Would ordinary homeowners be affected?

   It depends on the design. A wealth tax with a high threshold would leave almost all homeowners untouched. Reforming property tax, on the other hand, would affect most households, lowering bills for some and raising them for others.

2. What about pensions and small businesses?

   Many proposals exempt them or treat them more gently. The trade-off is that every exemption becomes a possible route for avoidance.

3. What if someone owns valuable assets but has little income?

   Common solutions include letting people delay payment until an asset is sold or passed on, paying in instalments, or paying in shares.

4. How would hard-to-value assets be assessed?

   Private businesses, art and land are harder to value than cash or listed shares. Options include standard formulas, independent assessors and less frequent valuations.

5. Could people move abroad or avoid the tax?

   Some will try. Exit taxes, international information sharing, public ownership registers and anti-avoidance rules can reduce this, but no system is watertight.

6. What might happen to investment and jobs?

   Economists disagree. Some argue that lower taxes on investment encourage businesses to grow. Others argue that much large wealth isn't productively invested, and that the effect depends heavily on design.

7. How much could it raise?

   Estimates vary widely, depending on how people are expected to change their behaviour and what collection costs. Any figure should come with its method and assumptions published.

What could the money be used for?

Tax design isn't only about who pays. It's also about what the money makes possible. Extra revenue could go towards:

• Lower taxes on earnings, so working people keep more of their pay.
• Better public services, such as health, education and social care.
• Housing and infrastructure, investing in the country's future.
• Lower borrowing, reducing government debt.

Some reforms could also be "revenue neutral", rebalancing who pays without raising more overall.
