Tax Finance for Construction Contractors
The construction sector faces more recurring tax timing challenges than almost any other industry. Monthly CIS remittances fall before contract payments are received; quarterly VAT bills arrive mid-project; PAYE and NI are due monthly regardless of whether invoices have been settled.
CIS, PAYE, and VAT Covered
Long payment terms (60-90 days are common in construction) create structural cash flow mismatches that tax bridging finance resolves - sector by sector, month by month.

What determines your rate
The construction cash flow structure
Construction businesses invoice at project stages but receive payment 30-90 days later. During that period, they continue to pay employees (PAYE/NI), subcontractors (CIS deductions), and suppliers (input VAT). The result is a structural gap between tax obligations and cash receipts that is inherent to the industry, not a sign of business failure.
CIS and VAT domestic reverse charge
The VAT Domestic Reverse Charge (DRC), applied to most construction services since March 2021, shifts VAT accounting from the subcontractor to the main contractor. This can create complex VAT positions where contractors are simultaneously collecting output VAT from clients and having input VAT assigned to them from subcontractors under the DRC. Where the DRC creates VAT refund positions, these can be bridged until HMRC processes the refund.
Retention
Construction retentions (typically 5-10% of contract value held by clients) are a further cash flow drain. Retention is only released at practical completion (50%) and end of defects liability period (50%) - often 12 months after completion. While retention does not create direct tax obligations, it contributes to the overall cash pressure that makes tax obligation timing challenging.
Developer vs contractor
Property developers (who build and sell) face a different tax profile to main contractors. Developers pay corporation tax on trading profits (at 25% for large companies), plus SDLT on land acquisition and VAT on certain sales. Contractors providing services pay VAT, CIS, and PAYE on labour. DBF's team can assist with both developer and contractor tax finance.
Worked cost example
Civil engineering contractor - monthly cash flow snapshot:
Contract invoiced: £600,000 (60-day payment terms - received March)
Subcontractor payments January: £180,000 (CIS 20% deducted: £36,000 remitted to HMRC by 19th)
PAYE/NI January: £28,000 (due 22nd)
VAT return Q3 (Oct-Dec): £45,000 (due 7 February)
Cash available January: £22,000
Tax obligations in January/February: £109,000. Cash shortfall: £87,000.
Bridge: £87,000 on commercial premises at 0.75%/month. Term: 3 months (March contract receipt).
Bridge cost: £1,988 interest + £1,305 fee + £2,000 legal = £5,293.
HMRC cost if all three missed by 30 days: £3,000+ in penalties and interest across all three.
Bridge: certainty of compliance + lower total cost on an annualised basis.
Rate context and outlook
Construction is consistently the highest-volume sector for HMRC tax arrears in the UK. The sector employs 2.4 million people, generates £175bn+ annually, and operates with structural cash flow challenges that make tax timing perpetually difficult. DBF's development finance and commercial bridging experience means we understand the construction sector context and can move quickly for contractor clients.

Frequently asked questions
Is tax bridging only for businesses in financial difficulty?
No - the majority of construction companies using tax bridging are fundamentally profitable businesses with a structural cash flow timing mismatch. They are not in financial difficulty; they simply invoice before they are paid, and HMRC's deadlines do not align with their payment cycles. Bridging is a cash flow management tool, not a distress indicator.
Can I use invoice finance instead of bridging for CIS and PAYE?
Invoice finance - where you advance against outstanding invoices - is an alternative or complement to bridging for construction cash flow. Where you have invoiced but not yet been paid, invoice finance provides immediate cash against those invoices. Bridging is more appropriate where you need to pay specific HMRC liabilities quickly using property as security. We can advise on whether invoice finance or bridging is more appropriate for your situation.
What is the VAT Domestic Reverse Charge and how does it affect my cash flow?
The VAT Domestic Reverse Charge (DRC), applicable to most construction services since March 2021, means the contractor (not the subcontractor) accounts for VAT on construction services. If you are the main contractor receiving services from subcontractors, the VAT is assigned to you. This can create a VAT credit position (more input VAT than output VAT) that is refunded by HMRC - but the refund takes time. Bridging covers the period between VAT payment and HMRC refund processing.
What if I am a subcontractor with CIS deductions withheld - can I bridge?
Subcontractors have CIS deducted at source (20% or 30%) from payments received. This creates a tax credit position - the CIS deductions withheld are offset against the subcontractor's SA or CT bill. If the CIS deductions exceed the tax liability, a refund is due. As a subcontractor, your bridging need is typically for SA/CT timing (same as any other business) rather than for monthly CIS remittances (which is a contractor issue).
Do you understand the construction sector specifically?
Yes - DBF arranges development finance and commercial bridging for construction projects regularly. We understand contract structures, retention, CIS mechanics, and the specific cash flow patterns of the construction industry. Our tax bridging service for construction contractors builds on this existing sector expertise.
