IR35 determinations that recruitment agencies can defend

Opinions without evidence do not travel far

IR35 status is decided on the facts of the engagement. Agencies that rely on a consultant's verbal comfort or a candidate's preference accumulate risk. When HMRC or an end client asks for the determination trail, missing questionnaires and unsigned assessments are expensive to reconstruct under time pressure.

A light, repeatable process beats occasional deep panic after a complaint or audit letter arrives.

What a workable process includes

Capture role facts: control, substitution, financial risk and whether the contractor is part and parcel of the client organisation. Record who made the determination and when. Keep contracts aligned with the working practices you described. Revisit when the role changes materially, not only at renewal by habit.

Train desks so the questionnaire is not a box-tick after the placement is already live. Finance and compliance need visibility when a role sits near the boundary between inside and outside IR35.

Money follows status

Inside IR35 changes take-home and can change which umbrella or PAYE route makes sense. Outside IR35 keeps limited company options open but still needs evidence. Agencies that explain both paths with numbers retain candidates and reduce complaints later.

File Easy supports recruitment agencies that want IR35-aware accounts and clearer contractor cost reporting tied to how desks actually place people.

Making finance useful on the sales floor

Give consultants a one-page view of contribution by desk and a short take-home comparison they are allowed to share. Pair that with the IR35 or CIS checklist so compliance is part of the placement conversation, not a later correction. Review debtor days alongside billings so volume targets do not hide collection risk. Agencies that let finance teach the floor in plain English lose fewer candidates to payslip surprises and fewer placements to avoidable status disputes.

A note on timing

Do the unglamorous work in quiet months: tidy records, agree policies, and book the mid-year review before winter pressure or year-end deadlines arrive. Most expensive accountancy problems started as postponed admin. A ninety-minute planning call in summer often prevents a frantic March. Build the habit even when nothing feels urgent, because urgency is usually a sign the calendar was empty of planning.
