With the balancing payment and first payment on account both due on 31 January 2026, it is worth checking your options early if funds are tight.

The final balancing payment for the 2024–25 tax year is due by 31 January 2026, which is also the deadline for filing your self-assessment tax return. This payment will settle any remaining tax owed for the year after taking account of payments on account already made.

In addition to the balancing payment, many self-assessment taxpayers will also have a first payment on account for the 2025–26 tax year due on the same date, which can make January a particularly challenging month for cash flow.

If you are struggling to meet the tax payments due by 31 January 2026 deadline, it is important to take action early, as there are options available to help manage the payment.

Taxpayers with self-assessment liabilities of up to £30,000 can use HMRC’s online Time to Pay (TTP) service to set up instalment payments. This can be done without speaking directly to an HMRC adviser and is available up to 60 days after the payment deadline.

To use the online Time to Pay service, you must:

If you do not meet these criteria, it may still be possible to agree a bespoke Time to Pay arrangement by contacting HMRC directly. These arrangements are assessed on a case-by-case basis and are usually based on your personal or business financial position.

HMRC will generally agree to extended payment terms where they believe the tax can be paid in full over time. However, if HMRC considers that delaying payment will not resolve the issue, they may seek immediate payment and can take enforcement action if the debt remains unpaid.

If you anticipate difficulty in paying your January 2026 tax bill, please do not ignore the problem. Please let us know and we can help you understand what options are available to you.

Aitch
I'm Aitch, the Founder and CEO of CIGMA Accounting Ltd. As a Chartered Management Accountant and as a CIMA member, I've spent more than 16 years helping businesses, entrepreneurs, landlords, and individuals with tax planning, accounting, and HMRC compliance. As a chartered accountant in London, I'm passionate about making complex tax matters easier to understand and helping clients make confident financial decisions. Over the years, I've advised start-ups, SMEs, established companies, and high-net-worth individuals across a wide range of tax and accounting matters. My expertise includes Corporation Tax, Self-Assessment, Capital Gains Tax, Inheritance Tax planning, R&D tax relief, capital allowances, international tax, and resolving complex HMRC compliance issues. Whether clients need a business accountant, tax accountant, or strategic tax advisor, my focus is always on delivering practical advice that creates long-term value. One of my specialist areas is Making Tax Digital (MTD). I've worked extensively with businesses preparing HMRC's digital reporting requirements, helping them move to cloud accounting, improve financial processes, and adopt technology that makes compliance more efficient. I regularly speak at Making Tax Digital roadshows, industry events, and educational sessions in collaboration with Zoho Books, sharing practical insights into digital accounting, tax legislation, and the future of the profession. Many business owners looking for the best accounting firm in London are not simply searching for an accountant they're looking for trusted advice, responsive support, and long-term value. That's the approach I've taken in building CIGMA Accounting. My team and I work closely with businesses across London and the UK, providing accounting services, tax advisory, bookkeeping, payroll, VAT, company accounts, and strategic tax planning tailored to each client's goals. Through this website, I share practical guidance on UK taxation, Making Tax Digital, HMRC updates, Corporation Tax, Self-Assessment, and business finance. My aim is to provide reliable, straightforward information that helps business owners understand changing regulations, reduce compliance risks, and make informed financial decisions with confidence.
