Using the 159 helpline

If a call from your bank feels suspicious, just hang up and dial 159 to be connected safely to your bank’s fraud team.

The 159 helpline was launched in September 2021. The helpline is designed to help consumers quickly and safely reconnect with their bank when they receive a suspicious or unexpected call about a financial matter. 159 now works for over 99% of UK retail bank customers, providing an extra layer of protection against phone scams.

If you receive a call that feels off, hang up and dial 159. This short code cannot be spoofed or imitated, unlike many regular phone numbers. It connects you directly to your bank’s fraud team, helping you verify the legitimacy of any request before acting.

The memorable number, with the digits forming a diagonal on the keypad "159", has already been used over 800,000 times since its launch. It works with most major UK banks, including Bank of Scotland, Barclays, First Direct, Halifax, HSBC, Lloyds, NatWest, Royal Bank of Scotland, Santander, Monzo, Starling and Virgin Money.

There are ongoing plans to expand and enhance the service including a proposal for having Ofcom designate 159 as a mandatory “Type A” number, like 999 or 111.

If you receive a call purporting to be from your bank that is concerning, calling 159 is a fast, secure way to protect yourself and your finances.

When dividends cannot be paid

Under the Companies Act 2006, dividends can only be paid from realised profits, never from capital, no matter what a company’s Articles of Association say.

Dividends can only be paid by a company out of profits available for distribution, not from capital, even if the company’s Articles of Association suggest otherwise. This rule is established under Companies Act 2006, section 830, and forms a key legal restriction on dividend payments.

Profits available for distribution are defined as a company’s accumulated, realised profits (from both revenue and capital), not previously distributed or capitalised, minus its accumulated, realised losses, provided these losses haven’t already been written off through a formal reduction or reorganisation of capital.

HMRC’s internal manuals go further and state that the Act lays down what may be termed the ‘balance sheet surplus’ method of determining profits available for distribution. Under this, a company can distribute the net profit on both capital and revenue at the particular time, as shown by the relevant accounts.

Additional rules apply to certain types of companies including investment and public companies.

What is the pension’s Money Purchase Annual Allowance?

The Money Purchase Annual Allowance (MPAA) is a pension rule designed to prevent individuals from gaining double tax relief on pension contributions. It targets situations where someone withdraws money from their defined contribution pension pot and then reinvests it, effectively receiving tax relief on the same funds twice.

The normal annual pension contribution limit is currently £60,000. However, once the MPAA is triggered the pension contribution limit is significantly reduced to the MPAA cap of £10,000 per year.

The MPAA is triggered when you start accessing your pension flexibly, such as by:

  • Withdrawing your entire pot as a lump sum (in full or in part).
  • Moving into flexi-access drawdown and taking income.
  • Buying a flexible annuity.
  • Exceeding withdrawal limits under a capped drawdown plan.

It does not usually apply if you:

  • Only withdraw up to a 25% tax-free lump sum allowance.
  • Buy a lifetime annuity.
  • Cash in a small pension pot of less than £10,000.

If applicable, the reduced pension allowance can affect future retirement planning and needs to be considered before making any pension withdrawals.

What happens if you cannot pay your tax bill?

If you cannot pay your tax bill, it’s crucial to contact HMRC as soon as possible. They may offer support through a Time to Pay arrangement, allowing you to repay your debt in instalments based on your financial situation. Ignoring the debt can lead to enforcement action, including visits to your home or business by HMRC or the use of debt collection agencies. The debt collection agencies are regulated by the Financial Conduct Authority and will only contact you by letter, phone, or SMS. They will not visit you in person at your home or place of work.

If these measures to do not work, HMRC can recover the debt using more serious measures. These include taking control of your possessions, recovering money directly from your bank account, adjusting your tax code or using court action. HMRC may also pursue debt through charging orders, deductions from wages or pensions or third-party debt orders.

If all else fails, insolvency proceedings may be started, including bankruptcy or winding-up orders. HMRC also has international recovery agreements that allow foreign tax authorities to collect UK tax debts if you live or have assets abroad.

If you are affected by any of these issues, please let us know so we can help you.
