Accountants for construction companies who put CIS and VAT right

Accountants for construction companies near Luton who check CIS, VAT and HMRC balances before cash gets tied up or a contract audit exposes old errors.

One construction company had taken a loan while its own money sat at HMRC after years of wrong returns. The problem only appeared when someone opened the portal and checked.

What changes when CIS and VAT are checked

01

Keep company cash available for live jobs

Find whether incorrect CIS or VAT returns have left company money sitting at HMRC.

02

Prepare the paperwork bigger contracts demand

Put employment contracts, HR documents and safety policies in place before year end.

03

See tax pressure before committing cash

Check what is due before committing to another supplier, hire or project.

The warning signs behind a bigger CIS problem

A filed return can still hide an error that repeats month after month.

  • CIS

    “I assumed every CIS return had been checked, but nobody had opened the HMRC portal for years.”

    Incorrect submissions can leave company money tied up while wages, materials and tax still need paying.

  • VAT

    “The VAT return was filed, but I couldn’t tell whether retentions and subcontractor invoices were treated correctly.”

    An error repeated each quarter can distort what the business owes or expects back.

  • Audit

    “We won the larger contract, then found our employment contracts and safety policies were not ready for review.”

    That can delay paperwork, absorb management time and weaken the evidence behind the year-end file.

  • Day 90

    What changes once construction advice is in the room?

    The HMRC portal is checked against the CIS and VAT submissions. Errors are traced before another return repeats them. Croner can then support employment contracts, HR and safety policies at a discounted subscription.

If your accountant cannot check your CIS and VAT position, explain your tax bill before it lands and reply this week, you have the wrong accountant

Answer these three questions about the accountant handling your company now.

Question 1 of 3

Could they tell you this week whether your CIS and VAT submissions match the HMRC portal?

What filing covers, and where advice begins

Year-end filing has a job, but construction decisions happen throughout the year.

Year-end filing

Accounts prepared after the year closes.

CIS and VAT submitted from the information supplied.

Corporation tax calculated for filing.

Questions handled when a return is due.

Advice during the year

HMRC balances checked against CIS and VAT.

Retentions and subcontractor treatment reviewed before submission.

Tax discussed before cash is committed.

Croner support considered before contract paperwork is tested.

Which construction accounting gaps still need checking?

A yes to each question means the main risks are already being covered.

  • 01

    Do CIS deductions match the subcontractor statements?

    Yes means the return and statements agree.

  • 02

    Does the HMRC portal match your own balance?

    Yes means unexplained differences have been checked.

  • 03

    Are retentions treated consistently for VAT?

    Yes means timing follows the supporting invoices.

  • 04

    Are subcontractor statuses checked before payment?

    Yes means deductions follow the status held.

  • 05

    Can each VAT return be traced to invoices?

    Yes means the submission has supporting documents.

  • 06

    Is corporation tax discussed before payment falls due?

    Yes means cash can be planned earlier.

  • 07

    Are payroll and CIS responsibilities kept separate?

    Yes means workers are handled under the correct route.

  • 08

    Can the year-end file support a contract audit?

    Yes means contracts, policies and supporting documents can be produced.

Which construction accounts need more than filing?

The service follows the places where cash and contract decisions can go wrong.

CIS

CIS that matches each deduction

Subcontractor status, deductions and HMRC submissions are checked against the underlying statements.

VAT

VAT that reflects the job

Invoices, retentions and available input VAT are reviewed before errors repeat.

Year end

Year end prepared before review

Accounts, tax and contract paperwork are brought together before they are needed.

How the first review becomes a working system

The work starts with the current problem and ends with a routine the team can follow.

Before day one

See whether the fit is right

Answer a few quick questions. If there is a fit, we arrange the free CIS and VAT check.

Day 30

Find where the balance came from

We inspect the HMRC portal, CIS submissions, VAT workings and available invoices.

Day 60

Put agreed corrections in motion

Supported corrections are prepared and the next filing follows the right treatment.

Day 90

Run the next job with fewer unknowns

CIS, VAT and year-end responsibilities follow a set schedule, with Croner considered where it fits.

Who gets the most from this review?

The company is limited, turns over at least £500k and works near Luton or the surrounding counties.

The team will provide invoices when needed and use the software recommended.

Sole traders, partnerships, transport firms and takeaways are outside this service.

The company can pay its fees now and is choosing on advice rather than price alone.

If that sounds close, answer a few quick questions for a personalised recommendation and, if there is a fit, the free review.

What construction directors ask before they switch

What does the monthly fee include for a construction company?

The scope can cover year-end accounts, corporation tax, bookkeeping, payroll, VAT and CIS, depending on what the company needs. Construction advice can include checking HMRC balances and preparing agreed corrections. The fee is fixed in writing before work starts, so the services included are set out before you switch.

Can we use Fiscal Umbrella if we already have an accountant?

Yes. Start with the intake quiz and a personalised recommendation. If there is a fit, the free review checks the current CIS, VAT and HMRC position before any move is discussed. That gives you a concrete reason to decide whether to stay or switch.

Do construction accountants make us change bookkeeping software?

A change is recommended when the current setup cannot support accurate bookkeeping, payroll, CIS or VAT submissions. Fiscal Umbrella supports Xero, QuickBooks, Hubdoc and Dext, with setup and training available. The review starts with what your team already uses and where mistakes or repeated manual work occur.

What happens with our current accountant if we switch?

Fiscal Umbrella contacts the existing accountant, requests the company files and handles professional clearance. The handover is planned around live filing dates so accounts, payroll, VAT and CIS responsibilities are assigned. You receive a written scope before work starts, showing what Fiscal Umbrella will handle.

Do accountants for construction companies need to be near the site?

Fiscal Umbrella works with construction limited companies near Luton, across Bedfordshire, Hertfordshire, Buckinghamshire and north London. Meetings can be held in Luton by appointment, while day-to-day work can run remotely. Local knowledge matters most when the accountant understands CIS, VAT, subcontractors and contract paperwork.

Can accountants for construction companies correct old CIS and VAT returns?

They can review previous submissions and prepare corrections where the documents support them. Fiscal Umbrella checks the HMRC portal, CIS statements, VAT workings and available invoices before advising what should change. No recovery or HMRC outcome is promised because the evidence and HMRC’s review determine what happens next.
