U.S. workers are starting 2026 with higher income thresholds for federal tax brackets and a larger standard deduction, shifts that can change how much tax employers withhold from paychecks, the Internal Revenue Service said.

Employees who expect different deductions or credits can update Form W-4, the form that tells an employer how much federal income tax to withhold.

Britain’s tax authority said 5.65 million people still need to file their Self Assessment tax return with less than a month to go before the Jan. 31 deadline. More than 6.36 million have already submitted a return, HM Revenue & Customs said on Monday. The filing date matters because it is also the deadline to pay any tax owed for the 2024/25 tax year. Anyone who misses it faces an automatic £100 late-filing penalty, even if they end up owing no tax, HMRC said.

New South Wales residents are being urged to check whether they are owed a share of about A$300 million sitting in Revenue NSW’s unclaimed money pool, the state government said. The register includes more than 800,000 items, with individual payments ranging from a few dollars to amounts in the millions. AAP News The push comes as households reset their budgets after the holiday period and look for relief wherever they can find it. NSW Finance Minister Courtney Houssos said, “This is money that belongs to residents of New South Wales, and we want to get that money back to you.” She said more than A$21 million was returned to NSW households last year.
