iXBRL Tagging for Companies House Accounts

<iXBRL/>

iXBRL stands for Inline eXtensible Business Reporting Language. It combines financial statements that people can read with structured data that software can interpret.

For UK companies, iXBRL is becoming increasingly important as Companies House moves towards software-based accounts filing. FinTags helps businesses and accountants prepare tagged financial statements by converting supplied accounts into the required digital format for the applicable reporting purpose.

Our service is designed for businesses that want specialist tagging support rather than managing the conversion process entirely in-house.

Who can use our iXBRL tagging service?

UK limited companies

Get support with tagging financial statements prepared for your company's reporting and filing requirements.

Micro-entities and small companies

Outsource the tagging of eligible accounts and ask us which service and pricing option suits your document size and reporting needs.

Accountants and accountancy practices

Reduce the time your team spends on repetitive tagging work. Use an external tagging service when internal capacity is limited or client volumes increase.

Companies with multiple entities

Coordinate iXBRL tagging across several companies with a consistent process and request volume-based pricing where applicable.

Businesses working with external accountants

If your accountant prepares your financial statements, FinTags can help with the tagging stage. Confirm the required output format and division of responsibilities before placing an order.

What Does Companies House iXBRL Tagging Involve?

iXBRL tagging associates reported financial information with standardised digital concepts, known as taxonomy tags. These tags identify items such as financial values, accounting concepts and relevant reporting details.

Depending on the accounts and applicable reporting requirements, the process may involve:

  • 1
    Identifying the relevant financial statement concepts
  • 2
    Applying appropriate taxonomy tags to the supplied accounts
  • 3
    Preserving the human-readable presentation of the statements
  • 4
    Reviewing the tagged output for consistency
  • 5
    Delivering the agreed output for the next stage of your filing process

The taxonomy and tagging requirements depend on the entity, accounts type and applicable rules. Not every company uses the same reporting taxonomy or filing route.

What documents can I provide?

Contact us to confirm which formats are supported for your order. Depending on the service selected, source documents may include:

WDOCX
XXLSX
PDFPDF
<iXBRL/>Tagged & reviewed
  • ✓Microsoft Word documents
  • ✓Microsoft Excel spreadsheets
  • ✓PDF financial statements
  • ✓Other agreed financial statement formats

Please provide the final accounts or the source files agreed with our team. If you need accounts preparation as well as iXBRL tagging, tell us before ordering so that we can clarify the scope.

Companies House iXBRL Tagging vs HMRC iXBRL Tagging

Companies House and HMRC have different reporting and filing purposes. Although both may involve iXBRL, their requirements and submission processes should not be treated as interchangeable.

Companies House annual accounts

Companies House receives statutory accounts for the public company register. The applicable accounts format and filing method depend on the company and the reporting route available to it.

HMRC

HMRC Company Tax Returns

HMRC receives Company Tax Returns, including CT600 submissions, and generally requires the relevant accounts and computations in iXBRL format where the applicable rules require it.

Need both services?

FinTags offers iXBRL-related services and separate filing services. Tell us whether you need tagging only, accounts filing, CT600 support or a combination. We will clarify what is included in your chosen service.

Important: purchasing an iXBRL tagging service does not automatically mean that your accounts or tax return have been submitted to a regulator.

How Our iXBRL Tagging Service Works

Step 1: Tell us about your accounts Share the entity type, reporting period, approximate document length and the purpose for which the tagged accounts are required.
Step 2: Submit your source documents Provide the agreed financial statements in a supported format. We will confirm any additional information needed to complete the order.
Step 3: Receive a quote We assess the scope of the work and confirm the applicable pricing, deliverables and expected turnaround before proceeding.
Step 4: iXBRL tagging and review Our team performs the agreed tagging and checks the output as part of the service process.
Step 5: Receive your completed files We deliver the agreed output for your review and the next stage of your filing process. Where submission is not included in your order, you or your appointed filing provider remain responsible for submitting the accounts.

Companies House Accounts Filing Changes: Prepare for April 2028

Companies House has announced that, from 1 April 2028, UK registered companies will be required to file annual accounts using commercial software in iXBRL format. The announced reforms also include changes affecting small companies and micro-entities.

The transition is intended to improve the quality, consistency and usability of financial information on the register.

If your company currently prepares or files accounts using a web-based or paper process, it is worth reviewing your future options with your accountant or filing provider.

FinTags can help you understand the iXBRL tagging work involved and discuss the service options available for your accounts. The right solution will depend on your company, the type of accounts you prepare and the filing route you choose.

Planning for the change? Contact FinTags to discuss your iXBRL tagging requirements.

Frequently Asked Questions

What is Companies House iXBRL tagging?

+

iXBRL tagging adds standardised digital tags to financial information so that the data can be processed by software while remaining readable as financial statements. The applicable requirements depend on the accounts and filing route.

Do all UK companies need to file accounts in iXBRL today?

+

Not every company currently uses the same filing method. Companies House has announced that commercial software filing in iXBRL format will be required from 1 April 2028. Check the current rules and requirements for your specific company before filing.

Can FinTags tag accounts prepared by my accountant?

+

Yes, you can enquire about having accounts prepared by your accountant tagged by FinTags. The source documents, required output and division of responsibilities should be agreed before the order begins.

Can I send accounts in PDF, Word or Excel?

+

These are common source formats for financial statement conversion, but the accepted formats and any preparation requirements depend on the service. Contact FinTags to confirm suitability before sending your files.

How much does Companies House iXBRL tagging cost?

+

The price depends on the document length, complexity and required output. Eligible smaller accounts may qualify for the iXBRL tagging offer from £20. Larger or more complex work can be quoted separately.

Is iXBRL tagging the same as filing accounts with Companies House?

+

No. Tagging prepares the financial statements in the agreed digital format. Filing is the act of submitting the accounts to Companies House. Confirm whether filing is included in your chosen order.

Is Companies House iXBRL tagging the same as HMRC iXBRL tagging?

+

No. The regulators have different reporting purposes and requirements. The relevant taxonomy, documents and submission process depend on the filing involved. Tell us whether your requirement relates to Companies House, HMRC or both.

Can FinTags help with multiple companies?

+

Accountancy practices and businesses with several entities can enquire about recurring tagging work and volume-based pricing. Share the approximate number of entities and annual workload so that we can assess the requirement.

How long does iXBRL tagging take?

+

Turnaround depends on the document length, complexity, completeness of the source files and current workload. Request an estimate before placing your order, particularly if you have an approaching filing deadline.

Does FinTags guarantee that Companies House will accept my accounts?

+

No tagging provider should imply that tagging alone guarantees regulatory acceptance. Acceptance depends on the accounts, compliance with applicable requirements, the submission process and other factors. FinTags can explain the checks included in the agreed service.

Can I order tagging without CT600 filing?

+

You can enquire about iXBRL tagging as a separate service. CT600 preparation and filing are distinct services and should only be included where specifically agreed.

What do I need to get a quote?

+

Have your company details, reporting period, source accounts, approximate page count and required filing destination ready. We can then clarify the scope and applicable pricing.
