The personal allowance
The income tax  personal allowance was already fixed at the current level until April 2026 and  will now be maintained for an additional two years until April 2028 at £12,570.
The government  will uprate the married couple's allowance and blind person's allowance by  inflation for 2023/24.
There is a  reduction in the personal allowance for those with 'adjusted net income' over  £100,000. The reduction is £1 for every £2 of income above £100,000. So there  is no personal allowance where adjusted net income exceeds £125,140.
The marriage allowance
The marriage  allowance permits certain couples, where neither party pays tax in the tax year  at a rate other than the basic rate (or intermediate rate in Scotland), to  transfer £1,260 of their personal allowance to their spouse or civil partner.
Comment
The marriage    allowance reduces the recipient's tax bill by up to approximately £250 a    year. To benefit from the marriage allowance one spouse or civil partner must    normally have no income or income below the personal allowance for the year.    Since the marriage allowance was first introduced there are couples who are    entitled to claim but have not yet done so. It is possible to claim for all    years back to 2018/19 where the entitlement conditions are met. The total tax    saving for all years up until 2022/23 could be over £1,000. A claim for    2018/19 will need to be made by 5 April 2023.
Tax bands and rates
The basic rate of tax  is 20%. In 2023/24 the band of income taxable at this rate is £37,700 so that  the threshold at which the 40% band applies is £50,270 for those who are  entitled to the full personal allowance.
Once again, the basic  rate band is frozen at £37,700 up until April 2028. The National Insurance  contributions upper earnings limit and upper profits limit will remain aligned  to the higher rate threshold at £50,270 for these years.
From 6 April 2023,  the point at which individuals pay the additional rate will be lowered from  £150,000 to £125,140.
The additional rate  for non-savings and non-dividend income will apply to taxpayers in England,  Wales, and Northern Ireland. The additional rate for savings and dividend  income will apply to the whole of the UK.
Scottish residents
The tax on income (other than savings and dividend income) is  different for taxpayers who are resident in Scotland from that paid by  taxpayers resident elsewhere in the UK. The Scottish income tax rates and bands  apply to income such as employment income, self-employed trade profits and  property income.
In 2023/24 there are five income tax rates which range between 19%  and 47%. Scottish taxpayers are entitled to the same personal allowance as  individuals in the rest of the UK. The two higher rates are 42% and 47% rather  than the 40% and 45% rates that apply to such income for other UK residents.  For 2023/24, the 42% band applies to income over £43,662 for those who are  entitled to the full personal allowance. The 47% rate applies to income over  £125,140.
Welsh residents
Since April 2019, the Welsh Government has had the right to vary the  rates of income tax payable by Welsh taxpayers (other than tax on savings and  dividend income). The UK government has reduced each of the three rates of  income tax paid by Welsh taxpayers by 10 pence. For 2023/24 the Welsh  Government has set the Welsh rate of income tax at 10 pence which has been  added to the reduced rates. This means the tax payable by Welsh taxpayers is  the same as that payable by English and Northern Irish taxpayers.
Tax on savings income
Savings income is  income such as bank and building society interest.
The Savings  Allowance applies to savings income and the available allowance in a tax year  depends on the individual's marginal rate of income tax. Broadly, individuals  taxed at up to the basic rate of tax have an allowance of £1,000. For higher  rate taxpayers the allowance is £500. No allowance is due to additional rate  taxpayers.
Savings income  within the allowance still counts towards an individual's basic or higher rate  band and so may affect the rate of tax paid on savings above the Savings  Allowance.
Some individuals  qualify for a 0% starting rate of tax on savings income up to £5,000. However,  the rate is not available if taxable non-savings income (broadly earnings,  pensions, trading profits and property income, less allocated allowances and  reliefs) exceeds £5,000.
Tax on dividends
Currently, the first  £2,000 of dividends is chargeable to tax at 0% (the Dividend Allowance). This  will be reduced to £1,000 for 2023/24 and £500 for 2024/25.
These changes will apply  to the whole of the UK.
Dividends received above  the allowance are taxed at the following rates for 2023/24:
    - 8.75% for  basic rate taxpayers
- 33.75% for  higher rate taxpayers
- 39.35% for  additional rate taxpayers.
As corporation tax due  on directors' overdrawn loan accounts is paid at the dividend upper rate, this  will also remain at 33.75%.
Dividends within the  allowance still count towards an individual's basic or higher rate band and so  may affect the rate of tax paid on dividends above the Dividend Allowance.
To determine which tax  band dividends fall into, dividends are treated as the last type of income to  be taxed.
Comment
Dividends on shares    held in ISAs and pension schemes are not subject to dividend tax and thus    will not be affected by the increase in rates.
Homes for Ukraine scheme
In March 2022  the government announced the Homes for Ukraine scheme, a humanitarian  sponsorship visa scheme allowing individuals, charities, community groups and  businesses in the UK to sponsor Ukrainians arriving in the UK. As part of this scheme  the government announced that sponsors would receive 'thank you' payments for  housing an individual or family.
Income tax and  corporation tax exemptions for 'thank you' payments made by local authorities  to sponsors under the Homes for Ukraine scheme will be introduced. Also,  temporary reliefs from the Annual Tax on Enveloped Dwellings and Stamp Duty  Land Tax will be introduced.
Pension tax limits
This measure supports  the government's efforts to encourage inactive individuals to return to work,  in particular those aged 50 and above, and it removes incentives to reduce  hours or leave the labour market due to pension tax limits. Legislation will be  introduced in Spring Finance Bill 2023 and will have effect from 6 April 2023.  This will:
    - Increase  the Annual Allowance from £40,000 to £60,000.
- Increase  the Money Purchase Annual Allowance from £4,000 to £10,000.
- Increase  the income level for the tapered Annual Allowance from £240,000 to £260,000.
- Ensure  that nobody will face a Lifetime Allowance charge.
- Limit the  maximum an individual can claim as a Pension Commencement Lump Sum to 25% of  the current Lifetime Allowance (£268,275), except where previous protections  apply.
- Change the  taxation of the Lifetime Allowance excess lump sum, serious ill-health lump  sum, defined benefits lump sum death benefit and uncrystallised funds lump sum  death benefit, where they are currently subject to a 55% tax charge above the  Lifetime Allowance, to taxation at an individual's marginal rate.
Legislation will be  introduced in a future Finance Bill to remove the Lifetime Allowance from  pensions tax legislation.
Comment
The government    states that evidence suggests recent increases in inactivity have been driven    primarily by those aged 50-64, and self-reported retirement has been the main    driver for these individuals to leave the labour market. This measure    supports individuals' ability to build up retirement savings and so improves    the financial incentive of work whilst continuing to balance the cost of    pensions tax relief.
Rendering void  assignments of income tax repayments
This  measure will apply to individuals entitled to income tax repayments from HMRC  who wish to use a business, accountancy firm or agent to facilitate their  access to a repayment. It will also affect the facilitating businesses,  accountancy firms and agents.
It  will remove a taxpayer's ability to legally assign to a third party their  income tax repayment, or their right to an income tax repayment. The effect of  this is that assignments of income tax repayments will have no legal effect and  the repayment will remain the property of the taxpayer.
This  will affect assignments of which notice is received by HMRC on or after 15  March 2023.
