HMRC has published its official employer rates and thresholds for the 2026-27 tax year, and while none of this will make a small employer leap for joy, it does matter if you run payroll, pay National Insurance or provide staff benefits. The figures apply from 6 April 2026 to 5 April 2027, so for many businesses this is the week to make sure payroll settings, budgeting assumptions and staff records are actually lined up with the new tax year.
For plenty of small firms, payroll errors do not start with anything dramatic. They start with one setting left unchanged, one outdated threshold in software, or one person assuming the accountant has already handled it. HMRC’s updated guidance gives employers the numbers to check now rather than discovering a problem after payslips go out.
What stands out for small employers
The standard personal allowance remains £12,570 a year, with the equivalent weekly and monthly figures of £242 and £1,048. For employers in England, Wales and Northern Ireland, the main PAYE income tax bands are still 20%, 40% and 45% above the relevant thresholds. Scotland continues with its own set of rates and bands, so multi-site employers or firms with remote staff north of the border need to be especially careful not to assume one size fits all.
On National Insurance, the main figures many smaller employers will care about are the lower earnings limit of £6,708 a year, the primary threshold of £12,570 and the secondary threshold of £5,000. HMRC’s guidance also confirms that the main employer National Insurance rate is 15% on earnings above the secondary threshold.
That may sound dry, but it feeds straight into real-world costs. If you are hiring, changing hours, taking on seasonal staff or reviewing prices this spring, payroll tax is part of the sums whether you like it or not.
Why this matters beyond the payroll desk
For a sole trader with no staff, this update may barely register. For any business with employees, it affects cash flow planning, margins and confidence around recruitment. A restaurant adding weekend cover, a local shop taking on an extra pair of hands, or a trades firm bringing in an apprentice all need to know the real employment cost, not just the headline wage.
It also matters for businesses that are already feeling squeezed. If sales are patchy or customers are more price-sensitive, even a modest payroll miscalculation can become an annoying dent in working capital. That is one reason it is worth treating HMRC’s annual rates page as a practical checklist rather than background noise.
If you want a second useful cross-check, BritishSME recently looked at how HMRC’s updated payroll calculators can help small employers sense-check deductions. Used together, the calculators and the rates page should make it easier to spot mistakes before they turn into awkward corrections.
What small businesses should check this week
First, confirm that your payroll software has been updated for the new tax year and that the right employee tax codes are in place. HMRC says the emergency tax codes from 6 April 2026 are 1257L W1, 1257L M1 and 1257L X, which is worth checking if you have had starters, leavers or messy payroll history recently.
Second, review any budget or hiring plans that were sketched out before April. Wage costs are only part of the picture. Employer National Insurance, pensions and any benefits can change the affordability of a role more than owners expect when they are moving quickly.
Third, double-check whether any staff fall into categories with special National Insurance treatment, such as apprentices under 25, employees under 21 or qualifying veterans. HMRC’s guidance sets out separate upper secondary thresholds for these groups, and missing those details can mean either overpaying or underpaying.
Finally, if your business operates across more than one UK nation, make sure the right tax treatment is being applied to the right people. Scottish income tax rates are not the same as those in the rest of the UK, and that is the sort of detail that quietly causes trouble if nobody owns it.
The sensible takeaway
This is not a flashy business story, but it is a useful one. HMRC’s 2026-27 employer rates are now the live numbers, and small employers should treat them as a prompt to check software, staffing costs and payroll assumptions now, while the tax year is still fresh.
It is far easier to spend 20 minutes reviewing payroll this week than to spend half a day unpicking errors later with HMRC, your accountant and a mildly unimpressed employee. Grim little admin job, yes. Still worth doing.
