Specialist CIS accountants for dryliners.

Drylining and partition installation sits squarely within CIS as specified construction operations. Dryliners typically work as sole-trader subcontractors with high materials costs (plasterboard, metal framework, fixings) and a strong GPS eligibility case once their turnover picture is accurately assessed.

What makes dryliners accounting different.

High materials costs excluded from GPS turnover

The GPS turnover test is applied to net CIS income, meaning materials are excluded. Dryliners with high plasterboard and framework costs may find their qualifying CIS turnover is significantly lower than their total invoice value, affecting eligibility.

Labour and materials split on invoices

Dryliners supply significant quantities of plasterboard, metal studs, track, fixings and insulation. Contractors should apply CIS deduction only to the labour element. Where the full invoice is deducted, money is lost on every job.

Multiple trade overlaps

Dryliners frequently carry out associated work including taping, jointing, skimming and ceiling fixing. Correctly identifying which elements fall within CIS-specified operations and which might not requires care at invoice and Self Assessment level.

Tool and equipment depreciation

Drylining requires a significant toolkit including screw guns, track cutters, board lifters and levels. These are legitimate capital allowance or expense claims but are frequently overlooked in self-filed returns.

What we do for dryliners.

CIS refund and Self Assessment

We identify all allowable expenses for drylining work, including materials, tools, mileage at 55p per mile, protective equipment and use-of-home where applicable, and file your Self Assessment to recover the maximum refund.

GPS eligibility assessment and application

We calculate your net CIS turnover correctly, assess all three GPS qualifying tests and manage the application to eliminate the 20% deduction if you qualify.

Deduction base review

We audit your payment and deduction statements to confirm the 20% rate is applied only to your labour income. Materials that contractors have incorrectly included in the deduction base are identified and corrected.

Questions from dryliners

Does drylining and partition installation fall under CIS?
Yes. Installation of partition walls, plasterboard systems and associated internal structural work is a specified CIS construction operation. Payments from contractors to drylining subcontractors are subject to CIS deduction unless the subcontractor holds Gross Payment Status.
My materials costs are high. Does that affect my GPS application?
It can. The GPS turnover test uses your net CIS income, which excludes materials. If your plasterboard, framework and fixings costs are high relative to your total invoiced amount, your qualifying turnover will be lower. We calculate the correct net figure as part of any GPS assessment to determine whether you meet the £30,000 sole-trader threshold.
