Introduction

If you run a construction business in the UK — sole trader, small subcontractor, or main contractor with a team — the Construction Industry Scheme adds complexity to your bookkeeping that general accounting software wasn’t built to handle.

You need software that verifies subcontractors with HMRC, applies the right deduction rate, produces payment and deduction statements, and files your monthly CIS returns directly. And, since 2021, correctly handles the VAT domestic reverse charge for construction services — a requirement most CIS software roundups skip entirely.

This guide covers which tools genuinely support CIS, which tier you need, and what to check before you commit.

What Proper CIS Support Actually Looks Like

Vague marketing copy often claims CIS capability when the reality is a manual workaround. Genuinely CIS-ready software should do all of the following.

Subcontractor verification. Verify a subcontractor’s status directly with HMRC before paying them, confirming their Unique Taxpayer Reference, whether they’re registered, and the correct deduction rate.

Automatic deduction rates. The three rates are 0% for gross payment status, 20% for registered subcontractors, and 30% for unverified subcontractors or unmatched details. The software should apply this automatically after verification, not leave you to remember.

Payment and deduction statements. Every subcontractor you pay must receive one showing the payment, the deduction and the rate applied. This is a legal requirement.

Monthly CIS returns filed directly with HMRC. Contractors must file by the 19th of the following month. Software that genuinely supports CIS files the return — it doesn’t produce a PDF for you to re-key into HMRC’s portal.

VAT domestic reverse charge handling. See below, because it catches people out.

Two Things That Catch Contractors Out

Nil returns still have to be filed. If you’re registered as a contractor and pay no subcontractors in a month, you must still submit a nil return or tell HMRC you’re temporarily inactive. Assuming “no payments, no return” is a common and expensive mistake.

The penalties escalate quickly. CIS late filing penalties start at £100 the day after the deadline and increase the longer a return is outstanding, with further penalties at two, six and twelve months. Check the current structure on GOV.UK. For a contractor filing twelve returns a year, the exposure from a system that doesn’t prompt you is real.

The VAT Domestic Reverse Charge

Since March 2021, the VAT domestic reverse charge applies to most construction services between VAT-registered businesses within CIS. Instead of the supplier charging VAT, the customer accounts for it.

This changes how invoices must be raised and how VAT returns are completed, and getting it wrong distorts your VAT position in both directions. Any accounting software you choose for construction needs to handle it properly, not just CIS deductions. Ask about it specifically — it’s less commonly advertised than CIS support and just as necessary.

The Best Accounting Software with CIS Support

A note on pricing and plan names. Several providers have restructured recently, and figures circulating in comparison articles — including plan names that no longer exist — are frequently out of date. Where we give a confirmed price we say so; where the tier carrying CIS needs verifying, we say that too.

1. Xero — Most Complete CIS Implementation

CIS: Native, including direct HMRC filing

Xero’s CIS functionality is genuinely good rather than cosmetic. Verify subcontractors in-platform, deduction rates apply automatically from HMRC’s response, and you can produce payment and deduction statements without leaving the software. Monthly CIS returns file directly with HMRC, which is the feature separating it from tools that leave the filing step to you.

Important: Xero has renamed its plans. The tiers are now Ignite (£16), Grow (£37), Comprehensive (£50) and Ultimate (£65), all ex-VAT. The old Starter, Standard and Premium names no longer exist, so any article telling you CIS sits on “the Standard plan at £33” is describing a tier structure Xero no longer uses.

CIS has historically been gated above the entry tier, so expect to need Grow or higher rather than Ignite. Confirm which of the current tiers includes CIS before subscribing — this is the single most important thing to check, and the plan rename means the answer may not match older guidance.

Verdict: The most complete CIS implementation available. Plan gating is annoying but the product earns it. Just verify the tier against current pricing, not a comparison table.

2. Zoho Books — Best Value for Native CIS

CIS: Native, contractor and subcontractor side

Zoho Books flies under the radar in the UK but has genuine built-in CIS support — not an add-on, not a workaround. Subcontractor verification, correct deduction rates, and the legally required payment and deduction statements. It also supports the CIS VAT reverse charge, which matters as much as CIS itself.

Confirmed pricing, per organisation rather than per user: Standard £10 a month billed annually (£12 monthly), Professional £20 (£24), Premium £25 (£30).

That per-organisation model is the differentiator. Every other tool here charges per subscription with user limits by tier; Zoho Books’ price covers your whole business, so adding your bookkeeper doesn’t change the bill.

There’s a free plan, subject to a turnover eligibility threshold we haven’t been able to confirm — figures quoted elsewhere vary. Verify it directly on Zoho’s UK pricing page. CIS is not on the free tier, so you’ll need a paid plan regardless. Confirm which paid tier carries CIS before subscribing.

Zoho Books also handles MTD for VAT and MTD for Income Tax. The interface is clean and the mobile app is genuinely usable on site.

The downside is a smaller UK accountant network. If you want your bookkeeper logging in, check they’re comfortable with Zoho before committing.

Verdict: Excellent value. If you’re price-conscious and want native CIS without a premium price tag, this deserves serious consideration.

3. QuickBooks Online — Good Product, Check the Tier

CIS: Native, including direct HMRC filing

QuickBooks has long supported UK construction with CIS baked in rather than bolted on — verification, deduction rates, statements and direct HMRC filing.

Confirmed UK tiers: Sole Trader Plus £10, Simple Start £16, Essentials £38, Plus £56, Advanced £123, all ex-VAT.

You’ll see references to a dedicated “Contractor plan”. That doesn’t appear in the current UK lineup above, so confirm which of these tiers actually includes CIS rather than looking for a plan that may no longer exist under that name.

The bigger issue is promotional pricing. QuickBooks UK runs heavy introductory discounts, and the ongoing rate after they expire can be several times the headline figure. Essentials at £38 and Plus at £56 are meaningfully more than most contractors expect. Establish the post-promotional price and when it applies before signing up.

The product itself is good — intuitive CIS handling, well-designed dashboard, and one of the largest UK accountant user bases, so your bookkeeper almost certainly knows it. Payroll integration is strong if you employ workers as well as engaging subcontractors.

Verdict: Solid CIS implementation. Verify both the tier and the post-discount price before committing.

4. Sage — Options at Two Different Scales

CIS: Native in the Sage 50 range

Worth separating two products often conflated.

Sage Accounting is the cloud-native small business product, confirmed at £20 a month ex-VAT for businesses with 1–19 employees. Confirm CIS availability and tier before assuming it’s included.

Sage 50 Accounts is the desktop-first range aimed at established contractors — larger operations managing payroll for employees alongside significant subcontractor volumes, and needing detailed job costing. CIS support is comprehensive: verification, automatic rates, statements and monthly return filing. It integrates with Sage Payroll, confirmed from £1.20 a month ex-VAT, which is useful when your workforce mixes employees and CIS subcontractors.

Sage 50 pricing is quoted on request and sits substantially above cloud-native competitors. The interface will feel dated if you’re used to modern SaaS tools.

Verdict: Sage Accounting is worth pricing if you want the Sage ecosystem at small-business scale. Sage 50 is powerful and reliable but likely overkill and over-budget for sole traders and very small contractors.

5. FreeAgent — Fine for Subcontractors, Not for Contractors

CIS: Partial — no direct HMRC filing of CIS returns

FreeAgent is popular with sole traders for its clean interface, and it’s free with a NatWest, Royal Bank of Scotland, Ulster Bank or Mettle business account — Mettle and Ulster are frequently left off that list, and Mettle is a free account in its own right. Otherwise it’s £19 a month ex-VAT for sole traders, £27 for partnerships and LLPs, £33 for limited companies.

It handles MTD for VAT and self-assessment well. CIS support is limited. You can record CIS deductions and track what’s been withheld, but it does not support direct filing of monthly CIS returns. You’d file separately through HMRC’s online service or your accountant.

The distinction that matters: if you’re a subcontractor receiving deductions, FreeAgent works reasonably — record what’s deducted and carry it into self-assessment. If you’re a contractor paying subcontractors, the absence of direct return filing is a significant gap, and filing twelve returns a year manually is exactly the error risk you’re buying software to avoid.

Verdict: Usable for subcontractors, insufficient for contractors. If you bank with NatWest Group or Mettle and you’re a subcontractor, free is hard to argue with.

What to Watch Out For

“CIS support” doesn’t always mean what you think. Several packages claim it while meaning you can manually record deductions in a spreadsheet-style format. That’s not CIS support — that’s you doing the work.

Plan gating catches people out. Check which tier CIS actually sits on before starting a trial. This is harder than it should be right now because Xero has renamed its plans and QuickBooks’ lineup has changed, so older comparison tables point at tiers that no longer exist.

Filing versus statement production. There’s a difference between software that produces a CIS return document and software that submits it. Confirm direct submission is available on the plan you’re considering.

Reverse charge handling. Ask specifically. CIS deduction support and VAT reverse charge support are separate capabilities.

FAQ

What is CIS and who does it apply to?

A HMRC scheme requiring contractors to deduct money from payments to subcontractors and pass it to HMRC as an advance against the subcontractor’s tax and National Insurance. If you’re a contractor you must register, verify subcontractors, deduct at the right rate and file monthly returns by the 19th. If you’re a subcontractor, deductions are credited against your tax liability.

Which accounting software has the cheapest native CIS support?

On confirmed pricing, Zoho Books Standard at £10 a month billed annually (£12 monthly), and that’s per organisation rather than per user. Verify the tier carries CIS before subscribing.

Can I handle CIS manually with standard accounting software?

Technically yes, filing through HMRC’s portal. But it introduces error risk, particularly around deduction rates, and you must remember nil returns in quiet months. For any contractor paying more than one or two subcontractors, dedicated software is safer and faster.

Do I still file a CIS return if I paid no subcontractors?

Yes. A nil return is required, or you can tell HMRC you’re temporarily inactive. Missing it triggers penalties exactly as a missed live return would.

Does CIS software also handle Making Tax Digital?

Most modern cloud tools support MTD for VAT. Note that MTD for Income Tax went live in April 2026 for sole traders and landlords with qualifying income — gross income before expenses, not profit — above £50,000, dropping to £30,000 in April 2027. Check your software is recognised for MTD for Income Tax specifically, as VAT approval doesn’t carry across.

Is CIS relevant for sole traders?

Yes, more often than people realise. A sole trader who hires subcontractors may well be a contractor under CIS, required to register, verify, deduct and file monthly. Working as a subcontractor, you need software that records deductions and carries them into self-assessment.

Conclusion: Our Recommendation

For most UK construction businesses managing multiple subcontractors, Xero has the most complete CIS implementation — direct HMRC filing, automatic deduction rates, a well-designed verification workflow. Confirm which of its renamed tiers includes CIS, because the answer isn’t what older guidance says.

If cost matters, Zoho Books is the value pick — native CIS and reverse charge support from £10 a month billed annually, priced per organisation rather than per user, with no compromise on the legal requirements.

If you’re a subcontractor rather than a contractor and you bank with NatWest, RBS, Ulster Bank or Mettle, FreeAgent free will likely cover you.

Avoid any software that promises CIS support without explicitly confirming direct HMRC return filing. That single detail — whether it submits the monthly return or leaves it to you — is the difference between a useful tool and an expensive spreadsheet. And ask about the VAT reverse charge while you’re at it.

Pricing and features correct at time of writing. Plans and capabilities change, and several providers in this article have restructured their tiers recently — always confirm current pricing and which plan includes CIS directly with the provider before purchasing. This article is general information about software, not tax advice; your CIS obligations, VAT reverse charge position and Making Tax Digital requirements depend on your circumstances, so check current GOV.UK guidance or consult a qualified accountant.
