NatWest is sending out emails to explain how government reforms will affect customers11:31, 06 Jul 2026NatWest is firing off emails to customers about an upcoming update that will affect account holders in the coming months. The correspondence outlines the choices customers will face next year, as certain significant changes come into force on April 6, 2027.‌NatWest ranks amongst the top four clearing banks in the UK. It boasts a market capitalisation of roughly £46.67 billion and looks after over 20 million customers, including one million business accounts. The high street giant maintains a substantial presence nationwide, with over 526 branches and 3,400 ATMs.‌With such a vast customer base, NatWest is reaching out via email to keep account holders in the loop on the latest developments. In a recent message titled "ISA changes in 2027 - are your savings in the right place?", the bank sets out how sweeping UK government tax reforms will alter how customers can utilise their NatWest ISA allowance.‌A statement within the email reads: "The government has shared more details on the ISA changes from 6th April 2027, and we'd like to help you understand what they could mean for you. As this is the last tax year before the new rules come into effect, now could be a good time to take a fresh look at your savings."This follows the government and HMRC introducing stringent anti-circumvention measures to stop savers from sidestepping the £12,000 cash limit, reports the Express.‌What's changing from April 6, 2027?For under 65's only:Your total ISA allowance will stay at £20,000 per year, but the amount you can add to a cash ISA will be limited to £12,000.You’ll no longer be able to transfer from a stocks and shares ISA to a cash ISA.For everyone:A 22% charge will apply to any interest paid on cash that’s held within a stocks and shares ISA.Stocks and shares ISAs can no longer be made up entirely of cash‑like investments.NatWest adds: "Now could be a good time to think about how you'd like to use your ISA allowance in future - and whether your savings are in the right place for your goals. Whether you're saving, investing, or a mix of both, taking time now to review your options could help your money go further ahead of the 6th April 2027 changes."‌While your overall annual ISA limit remains at £20,000, the government is capping the amount of fresh funds you can deposit into cash accounts in a bid to encourage retail investment. If you're under 65, you're restricted to adding no more than £12,000 per tax year into a Cash ISA.The remaining £8,000 must be placed into non-cash options, such as a Stocks and Shares ISA. If you're aged 65 or over, this restriction won't apply to you.‌You can still put your entire £20,000 allowance into a Cash ISA. Any tax-free funds you accumulate in your NatWest Cash ISA before 6 April 2027 will remain fully safeguarded and will continue to earn tax-free interest.A statement on Gov.uk reads: "In order to protect the integrity of the new cash ISA limit and ensure the reforms achieve their intended aim of encouraging retail investment so savers get more from their investments/savings, the following rules will be introduced to prevent the following:subscribe up to £20,000 cash in a non Cash ISA and leave it there long-term earning tax-free interestsubscribe £20,000 to a non Cash ISA and then transfer those funds to a Cash ISAsubscribe £20,000 to a non Cash ISA and use the funds to purchase wholly cash-like investments".Article continues belowNatwest says any money you already hold in a Cash ISA, up until April 5, 2027, should not be affected and will remain tax-free. There are also changes to Stocks and Shares ISA's but these won't affect your Cash ISA.You can find more details here on the Government website. These proposals are still subject to legislation
