Marcus Okafor's van leaves Morgan Close at 6:40 every morning, and for most of 2026 it came back to the best year he's ever had. September alone: £6,100 invoiced — a record he mentioned, casually, roughly forty times. Self-employment is freedom, Marcus will tell you, and last year freedom paid.

It also, this being the part freedom is quieter about, ran his invoices through no payroll, deducted no tax, and asked no questions. Every pound landed whole in the joint account, looking spendable. Some months £6,100 landed. One month, June, £950 did. It evens out, Marcus says. It'll even out.

On the 28th of December — Jade having asked, with baby Amara on her hip and a particular tone, whether he'd "done the return yet" — Marcus finally sits down with the laptop and files his self-assessment. The calculation takes HMRC's website four seconds.

£5,200. Due 31 January. Income tax, Class 4 National Insurance, and — the line nobody warns first-timers about — a payment on account: an advance on next year's bill, because HMRC has decided it would rather not wait either.

The joint account holds £2,340. Jade's maternity pay covers roughly a fortnight of the mortgage. The van needs two tyres before its MOT. And it is thirty-four days until the deadline, which Marcus reads three times, as though the number might even out too.
