Filing obligations for private limited companies
Those responsible for the accounts and tax compliance of private limited companies must ensure they are fully aware of the relevant obligations and statutory deadlines.
Following the end of each financial year, a private limited company is required to prepare full annual accounts and submit a Company Tax Return. The deadline for filing the first set of accounts must be filed with Companies House within 21 months of the date of incorporation. Thereafter, annual accounts must be filed within 9 months of the end of each financial year.
Corporation Tax is payable 9 months and 1 day after the end of the relevant accounting period. As a result, the tax liability will typically fall due before the filing deadline for the Company Tax Return.
In most cases, the Company Tax Return must be submitted within 12 months of the end of the accounting period. Filing is required to be completed online in iXBRL format, using either HMRC’s own software or approved third-party software.
The Corporation Tax accounting period will generally correspond with the 12-month company financial year covered by the annual accounts.
Penalties may be imposed by both Companies House and HMRC for late filing or non-compliance, and it is therefore essential that all deadlines are carefully monitored and adhered to.
