HM Revenue and Customs is reminding millions of Self Assessment taxpayers to prepare for the July 31, 2026, deadline for their second payments on account for the 2025 to 2026 tax year.
The UK government's tax arm warned that individuals face interest, financial penalties, and cash-flow shocks if they miss this annual deadline.

Payments on account are two annual installments that help spread the cost of a customer's tax bill, with each payment usually representing half of the previous year's tax bill.
Taxpayers must make these payments unless their tax owed last year was under £1,000, or if they already paid over 80% of their total tax bill through PAYE or interest deductions.
HMRC officials stated that the agency's mobile application remains the fastest method to clear these bills, noting that nearly 2 million taxpayers have used the app since its January 2022 rollout.
Taxpayers can also establish weekly or monthly payment plans on GOV. UK to manage the costs.
"We know managing a Self Assessment tax bill isn't always straightforward and we are here to help," said Myrtle Lloyd, HMRC's Chief Customer Officer.
Lloyd added that various resources are active online to assist taxpayers in completing their requirements.
"From paying instantly via the HMRC app to spreading the cost through a payment plan, there's support available for every customer," she said.
Experts Urge Year-Round Organization
Financial experts across the UK are urging self-employed workers and landlords to keep their accounts organized throughout the year to avoid being caught off guard by the mid-summer deadline.
