What changes once your CIS is checked

01

See what HMRC says you owe

Your HMRC balance is checked against the CIS and VAT returns already filed.

02

Correct problems before they keep growing

Missing deductions and inconsistent returns are identified before another filing repeats them.

03

Know who owns every deadline

Each return has an agreed owner during the handover and throughout the year.

Where CIS problems hide before the deadline

A submitted return can conceal mistakes that affect cash, VAT and the next contract.

  • CIS

    “I assumed the CIS returns were right because they had been filed for years.”

    Filing alone does not show whether deductions match the company’s HMRC account.

  • VAT

    “Our HMRC balance never matched what the accountant said we had paid.”

    Without a check, the company cannot tell whether money is due or sitting at HMRC.

  • Contract

    “A larger contract asked for paperwork nobody had kept ready for review.”

    Missing contracts and safety policies can hold up a larger project review.

  • Day 90

    What changes once the advice is in the room

    CIS and VAT are checked together. The HMRC portal is matched to what was filed. Problems are raised while there is still time to act.

Quick check · no email

If they cannot explain your CIS balance, check whether your VAT returns agree, and reply this week, you have the wrong accountant

Answer these three questions about the accountant handling your construction company today.

Question 1 of 3

Could they tell you this week whether your CIS deductions match your HMRC account?

Where year-end filing ends and CIS advice begins

Both approaches can file accounts, but construction companies often need decisions made earlier.

A year-end filing service

It submits the accounts after year end.

It prepares returns from the information supplied.

It answers filing questions as they arise.

It may suit a company with simple subcontractor activity.

CIS and VAT advice through the year

It checks CIS against the HMRC portal.

It reviews VAT alongside subcontractor payments.

It raises missing information before filing.

It explains balances before you commit money to a supplier or hire.

Eight checks before the next CIS return

Each answer shows whether the current setup can support the next filing.

  • 01

    Are all subcontractors verified before their first payment?

    The verification result should stay with that payment.

  • 02

    Do CIS deductions match each monthly return?

    A mismatch can change the balance shown by HMRC.

  • 03

    Are deduction statements sent after every CIS month?

    Late statements leave subcontractors unable to match deductions.

  • 04

    Does the HMRC portal agree with your filings?

    An unexplained balance needs checking before the next return.

  • 05

    Is VAT reviewed alongside CIS and retentions?

    One return can expose a problem in the other.

  • 06

    Can every payment be tied to an invoice?

    Missing invoices weaken any correction sent to HMRC.

  • 07

    Is each deadline assigned during an accountant handover?

    Written responsibility prevents either side assuming the other will file.

  • 08

    Are contracts and safety policies ready for review?

    Discounted Croner support can be arranged where it fits.

What sits behind a correct CIS return

CIS works properly when subcontractor payments, VAT and HMRC balances are checked together.

CIS

Subcontractor returns that match HMRC

Deductions, statements and monthly returns are checked against the company’s HMRC account.

VAT

VAT checked beside every CIS issue

VAT filings are reviewed where subcontractor payments, retentions or earlier corrections affect them.

Contracts

Paperwork ready for larger projects

Discounted Croner support can cover HR, employment contracts and safety policies.

How the first ninety days put CIS right

The work begins with the current position, then moves through checking, handover and the next filing.

Before day one

The CIS gap is identified

Answer a few quick questions about the company, software and outstanding HMRC items. If there is a fit, the free review follows.

Day 30

Your filings are checked

The HMRC portal is matched to CIS returns, VAT filings, deductions and balances. Any unexplained item is listed.

Day 60

The handover has one owner

Fiscal Umbrella requests the information from your current accountant and assigns each filing date during the changeover.

Day 90

The next return follows the plan

Subcontractor checks, VAT and deadlines follow an agreed process. Problems are raised before the next filing.

Who gets the most from the CIS check

Sole traders, partnerships and LLPs are outside this limited company service.

Construction companies below the practice’s turnover threshold are not a fit.

Transport, haulage, courier and taxi companies are not taken on.

Free HMRC enquiry or investigation support is not offered.

The intake quiz checks these points first, then offers the free review when there is a fit.

The questions to settle before you switch

What does a CIS accountant in Luton include in the monthly fee?

The written scope can include CIS returns, VAT, bookkeeping, payroll, year-end accounts and corporation tax. It also states who handles subcontractor checks and HMRC correspondence. Fiscal Umbrella agrees the fixed fee before work begins, so every included task is written down.

Can a CIS accountant in Luton review us if we already have an accountant?

Yes. The first review can be completed while your current accountant remains appointed. It checks the HMRC portal, recent CIS and VAT filings, upcoming deadlines and any unexplained balance. If a switch makes sense, Fiscal Umbrella starts the handover after you accept the written scope.

Do we have to move our construction company onto different software?

A software move is recommended when the present setup cannot support accurate CIS, VAT, payroll or bookkeeping. Fiscal Umbrella first checks what you use and how information reaches it. If a change is needed, the recommended setup and your responsibilities are explained before work starts.

What happens to our current accountant when we switch?

Fiscal Umbrella contacts your current accountant, requests the information needed and handles professional clearance. The handover typically takes two to four weeks, with filing dates watched throughout. Your previous accountant stays responsible until the agreed changeover point, so responsibility for each return is clear.

Can you check old CIS and VAT returns for mistakes?

Yes, where the company provides the returns, payment statements and HMRC account details needed for a proper check. Fiscal Umbrella can identify inconsistencies and prepare corrections when the evidence supports them. No refund or HMRC result is promised, and an open enquiry is reviewed before any scope is agreed.

Do I need a local CIS accountant in Luton?

No. Local construction companies can meet in Luton by appointment. Most work can also be handled by phone, Zoom, Teams or WhatsApp. Being nearby helps when a contract, audit request or HMRC letter needs discussion. CIS and VAT are still checked against the same company information.
