The VAT Domestic Reverse Charge (DRC) for the Construction Industry

The Construction Industry Domestic Reverse Charge (DRC) took effect in March 2021, shifting VAT accounting from supplier to customer in the construction supply chain. Five years on, most construction subcontractors and main contractors operate it competently — but mistakes continue to cost money. The key compliance points: applying DRC correctly on CIS invoices, validating end-user certificates that override DRC, the 5% disregard rule for mixed supplies, the scaffolding distinction (hire vs erection), and reconciling DRC transactions in cloud accounting software.

How the DRC actually works

For services within the CIS scheme between two VAT-registered parties:

1. 1Subcontractor issues invoice to contractor without charging VAT.
2. 2Invoice notes: "Reverse charge: customer to pay the VAT to HMRC."
3. 3Subcontractor records the supply on their VAT return as a sale (in box 6) but does NOT pay output VAT to HMRC.
4. 4Contractor records both the input AND output VAT on their VAT return — net effect: zero VAT change.
5. 5End-user (final customer): DRC does NOT apply; the contractor charges VAT normally.

When DRC applies

• Construction services within the CIS scheme.
• Both supplier and customer VAT-registered.
• Both supplier and customer registered for CIS.
• Customer is NOT the end user.
• Standard or reduced-rate (5%) supplies; zero-rated supplies excluded.

End-user certificates

Where the customer IS the end user (final consumer of the construction service), DRC does NOT apply, but the customer must provide an end-user certificate to override:

1. 1Customer issues written end-user notification to supplier.
2. 2Supplier validates the notification (confirm it covers all relevant works).
3. 3Supplier reverts to standard VAT charging on the invoice.
4. 4Both parties retain records for 6 years.

The 5% disregard rule

For mixed supplies (some construction services, some non-construction services on a single invoice):

• If construction services are 5% or less of the total invoice value: ignore DRC. Treat the entire invoice as standard VAT.
• If construction services exceed 5%: apply DRC to the construction portion.
• Test on a per-invoice basis.
• For most subcontractors, the 5% disregard rarely applies; their work is overwhelmingly construction.
• For mixed-trade contractors (e.g., architect supplying design + minor site supervision), the disregard can apply where site work is incidental.

DRC vs standard VAT on scaffolding

Scaffolding supplies have a specific distinction:

• Hire of scaffolding only (no erection or dismantling): NOT a construction service, standard VAT applies.
• Erection and dismantling of scaffolding (with or without continuing hire): IS a construction service, DRC applies.
• Combined hire-and-erection: DRC applies to the whole supply.
• Pure hire-only scaffolding: standard VAT.

DRC cash flow impact on subcontractors

Mitigations:

• VAT registration for input VAT recovery (still beneficial despite DRC on sales).
• Cash Accounting Scheme for non-DRC sales: defers VAT until customer pays.
• Cash flow forecasting: account for the working capital reduction explicitly.
• Invoice timing: invoice early in the month to compress receivables cycle.

DRC to standard rates on commercial conversions

For conversions between residential and commercial use, VAT treatment varies:

• Construction of new dwellings: zero-rated supply (DRC does not apply to zero-rated).
• Conversion of commercial to residential: 5% reduced rate (DRC applies if both parties VAT and CIS registered).
• Conversion of residential to commercial: standard rate (DRC applies).
• Major refurbishment of existing residential: standard rate, DRC applies.
• Commercial-to-commercial (e.g., office to retail): standard rate, DRC applies.

Reconciling DRC in cloud accounting

Xero, QuickBooks and Sage all support DRC accounting:

1. 1Set up DRC tax codes in the chart of accounts (typically pre-built in Xero/QB).
2. 2Apply DRC tax code on subcontractor invoices issued to contractors.
3. 3Apply DRC tax code on subcontractor invoices received (as customer reverse charge).
4. 4VAT return shows DRC sales (Box 6) and DRC purchases (Box 7) without VAT in Box 1 or Box 4.
5. 5Periodic review: confirm DRC vs non-DRC classifications correct for each customer/supplier.
