Construction Industry Scheme verification, deductions and monthly returns for contractors.

• Subcontractor verification with HMRC

• Monthly CIS returns and statements

• Deduction offsets against PAYE liabilities

• Gross payment status support

The rules that shape this work

Contractors must file a monthly CIS return by the 19th of each month, even in a month with no payments, when a nil return is required. Late returns attract a £100 penalty immediately, rising with delay.

Deduction rates are 20% for verified subcontractors and 30% where verification fails, with 0% for gross payment status. A limited company subcontractor offsets CIS suffered against its PAYE liabilities.

Thresholds, rates and deadlines quoted here reflect the 2026/27 UK position. Check current GOV.UK guidance, or ask us, before you rely on them for your own company.

How we run it

We start by looking at the last filed accounts, your current records and your filing dates, then confirm a fixed scope and fee in writing.

Once the work is live you get reminders ahead of each deadline, a named person to ask questions, and a plain-English summary when the figures are ready, not a PDF with no explanation.

Frequently asked

CIS returns: questions directors ask

We are a subcontractor company. How do we get the deductions back?

Offset the CIS suffered through the EPS each month against PAYE liabilities, and reclaim any excess after the tax year end.

Does CIS apply to us if we only do occasional building work?

It can. Businesses spending significantly on construction operations may fall in as deemed contractors even if construction is not their trade.

What records are needed for cis returns?

Keep bank statements, sales and platform reports, purchase invoices, payroll records, VAT workings, finance agreements and Companies House correspondence. We confirm the exact list at onboarding and identify gaps before a filing deadline becomes urgent.

How much does help with cis returns cost?

The fee depends on transaction volume, record quality, VAT and payroll requirements, historic catch-up and the level of reporting needed. We agree a fixed scope and price before technical work starts, with published packages available on our fees page.

Can you take over cis returns from another accountant?

Yes. We request professional clearance, collect the prior records and authorities, check the next Companies House and HMRC deadlines, and give you one clear handover list. The process is normally completed remotely.

Can cis returns be handled online?

Yes. We work through secure cloud records, scheduled reviews and digital approvals, while keeping a named team available by phone, video call and email. Clients can also visit our Morden office by appointment.

Which accounting software works best for cis returns?

We regularly work with Xero, QuickBooks, FreeAgent, Sage and connected sales or expense apps. The right setup depends on transaction volume, integrations and the reports you need, not simply the software brand.

What tax deadlines matter for cis returns?

The relevant calendar may include annual accounts, Corporation Tax payment and return dates, confirmation statements, VAT returns, payroll submissions and Self Assessment. We map the dates from your company year end and registrations.

Can I get free basic tax advice about cis returns?

Yes. You can ask a straightforward initial question without charge. Calculations, filings, written advice, planning and HMRC correspondence are scoped and quoted before work begins.

“Accotax have been our accountants for many years now. We maintained them because of their professionalism. In the last couple of years I have been working with Imran, who has been very professional and helpful in guiding us through the whole process, explaining and clarifying every aspect of it. Very prompt in responding to questions and patient with us even when we seem to be slow.”
Mansur Liman · Long-standing company client
“We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.”
Mael Leboucher · Year end accounts & bookkeeping

My personal allocated manager, Umer, provides tailored services for both of my companies, adapting as I expand and ensuring everything runs smoothly.
