Who We Are
Accountants who understand the construction start-up journey
Launching a construction business involves choices, sole trader versus limited company, CIS registration timing, VAT registration threshold planning that shape your tax position for years. We work with founders from incorporation through the first few contracts, setting up systems that scale as the business grows.
- Business structure advice: sole trader, partnership, or limited company
- CIS and VAT registration handled correctly from the outset
Getting Your Structure Right From Day One
Choose the right business structure before you take your first contract
Whether to trade as a sole trader, partnership, or limited company affects your tax rate, personal liability, and how CIS deductions and gross payment status applications work. Limited companies pay Corporation Tax at 19-25% depending on profit level, while sole traders pay Income Tax and National Insurance on profits directly, and each structure has different implications for CIS deduction treatment and future gross payment status eligibility.
We model both structures against your expected turnover and contract type before you register, so you start with the setup that suits your business, not a default choice.

Compliance Rate
CIS & VAT Registration for New Businesses
Register correctly the first time, avoid the 30% deduction trap
New subcontractors who delay CIS registration are deducted 30% instead of 20% on every invoice until registered, an avoidable cash flow hit in your most vulnerable early months . We register you for CIS immediately, and advise on VAT registration timing, including whether early voluntary registration benefits your cash flow given the reverse charge rules on subcontracted work.

Common Pain Points
The Main Tax Challenges Construction Start-Ups Face
New construction businesses face compliance obligations from their very first invoice, often with no back-office support in place yet.
Wrong Business Structure Chosen Too Early
Incorporating (or staying a sole trader) without modelling the tax impact can lock in a higher tax burden that’s costly to unwind later.
Delayed CIS Registration
Every month spent unregistered means 30% deductions instead of 20%, directly hitting cash flow when a start-up needs it most.
No Bookkeeping System from Day One
Start-ups that delay setting up proper bookkeeping struggle to reconstruct records at year end, risking inaccurate returns and missed expense claims.
Under-Claimed Set-Up Costs
Tools, vehicles, and equipment purchased before trading formally begins are often missed entirely when claiming capital allowances.
Undercapitalised for Tax Payment Dates
New businesses frequently underestimate Corporation Tax, VAT, and CIS payment dates, leading to unexpected bills that strain limited start-up cash reserves

★★★★★
“We had no real idea which contracts were making money until they built us a proper job-costing system. Now we price the next tender based on actual data, not guesswork.”
★★★★★
“Every site brings its own VAT and SDLT questions, and they have never once been slow to answer. Switching from our old firm was the easiest financial decision we have made in years.”

FAQS
Common questions from Construction Start-Ups
Should I set up as a sole trader or limited company?
It depends on your expected profit, liability appetite, and growth plans — a limited company often becomes more tax-efficient once profits exceed a certain level, but carries more administrative obligations.
Do I need to register for CIS before I take my first contract?
Yes, if you’re providing construction labour to a contractor, you should register before your first invoice to avoid the 30% unregistered deduction rate .
When should I register for VAT?
How soon can a new business apply for gross payment status?
You must meet HMRC’s turnover and compliance tests, which typically requires a trading history and clean payment record, so it’s rarely available in year one but achievable within a couple of years.
Why choose Construction Tax Accountants for a start-up?
We set up construction businesses correctly from the first invoice, so you avoid the registration delays and structural mistakes that cost new firms money in year one.
