As summer approaches, there's one crucial deadline demanding attention - 6th July marks the cut-off for submitting P11D forms.

"Every year we see businesses caught out by the P11D deadline," warns Tracy Gill, Payroll Manager at Whitley Stimpson. "It's easy to assume that because you've handled year-end P60s, you're done with HMRC reporting. But if employees receive benefits beyond basic salary, there's still work to be done."

The P11D form captures employment extras like company cars, private health insurance or gym memberships. If it's a perk with monetary value, it needs declaring.

Alongside the P11D, employers must submit a P11D(b) form by the same deadline. This declares Class 1A National Insurance owed on benefits – contributions only employers pay. Payment isn't due until 19th July by cheque or 22nd July electronically, but the declaration cannot wait.

"The complexity increases when you consider that even if you've processed some benefits through regular payroll, you might still need a P11D(b) if there's Class 1A National Insurance due," explains Tracy.

Even businesses owing no Class 1A National Insurance cannot ignore HMRC correspondence. If you've received a P11D(b) reminder but have no liability, you still need a 'nil return' to avoid penalties.
