Direct Wage Tax Collection Expansion: Increased Workers to Have Tax Deductions Directly from their Salaries by HMRC
Starting from April 2027, a significant change is on the horizon for UK savers. Banks and building societies will be legally required to collect National Insurance (NI) numbers from all new and existing savings account holders [1][2][3]. This move aims to automate the taxation of savings interest, improving the HM Revenue & Customs (HMRC) ability to identify and tax savers earning interest above their personal savings allowance without requiring self-assessment tax returns for many.
Key points about these changes include:
- The requirement applies only to savings accounts, not to current accounts [1][2][3].
- This will help HMRC reduce errors caused by about 20% of interest data currently being “unreadable,” meaning tax owed could not be automatically collected [1][2][3].
- As a result, more taxpayers will have savings tax deducted directly from their pay, simplifying compliance [1][2][3].
- Basic-rate taxpayers can earn up to £1,000 in savings interest tax-free, higher-rate £500, and additional-rate taxpayers have no allowance [1].
- Estimated costs: HMRC anticipates spending around £35 million on implementation, while banks may each spend up to £10 million [1].
- The move has raised some privacy concerns regarding increased state intrusion [1][3].
Regarding National Insurance numbers themselves, the change is primarily about the mandatory collection and linking of NI numbers to savings accounts for tax purposes, rather than changes to the NI number system [1][2][3].
In summary, from April 2027, the new UK rules require savings providers to obtain and share customers’ NI numbers with HMRC to enable automated, accurate savings interest taxation and reduce the burden of self-assessment tax returns for many savers.
No other fundamental changes to National Insurance numbers or their general use are indicated as part of these April 2027 rules [1][2][3]. It's essential for savers to keep records of their savings accounts and interest earned to provide evidence to HMRC if they believe they have been incorrectly taxed.
Using cash ISAs remains an essential way to protect hard-earned cash from tax until further changes are announced. As always, it's advisable for savers to double-check their records with their taxes, or ask their accountant or financial adviser for help.

- The changes in UK personal finance regulations from April 2027 will necessitate savers to provide their National Insurance numbers to savings account providers, enabling automatic and accurate taxation of savings interest.
- Inadequate records of savings accounts and interest earned could lead to potential disputes over taxation, necessitating careful monitoring and record-keeping by UK savers for future reference with HMRC.
