Frequently asked questions

What is the deadline for submitting a Corporation Tax return?

A Company Tax Return is normally due twelve months after the end of the accounting period, whilst any Corporation Tax owed must be paid within nine months and one day of the period end. Meeting both deadlines is vital to avoid penalties and interest. Qualified accountants in Harrow can prepare and file the return on time.

Why should a limited company use a qualified accountant for tax returns?

ACCA, ICAEW and AAT qualified accountants understand HMRC legislation and can calculate liabilities accurately, apply reliefs and prepare compliant accounts. They also handle VAT and Self Assessment matters for directors. Using a regulated professional reduces the risk of errors, penalties and HMRC enquiries, giving business owners confidence in their tax position.

Can an accountant help with both VAT and Corporation Tax?

Yes. Many firms listed on AccountingFirms provide combined services covering VAT registration, VAT returns, Corporation Tax returns and Self Assessment. This joined-up approach ensures figures are consistent across all filings and deadlines are monitored. It is especially useful for growing companies that need ongoing compliance support from one trusted provider in Harrow.

What information is needed to prepare a Corporation Tax return?

Accountants typically require statutory accounts, bank statements, sales and purchase records, payroll details, expense receipts and information on capital assets. Directors should also provide details of any dividends, loans or R&D activity. A qualified professional will use this information to prepare accurate accounts and submit the return to HMRC.

How does AccountingFirms help businesses find tax specialists?

AccountingFirms was established in 2019 and built by ICAEW and ACCA accountants. The directory allows users to browse local firms, compare providers and connect with verified professionals who specialise in Corporation Tax, VAT and Self Assessment. This makes it easier to choose a suitable accountant in Harrow based on expertise and service needs.

Are penalties charged for late Corporation Tax returns?

HMRC charges automatic penalties for late filing, starting at one hundred pounds and increasing with further delays. Interest and additional penalties may also apply to unpaid tax. Instructing a qualified accountant early helps ensure returns are prepared and submitted before the deadline, avoiding unnecessary costs and reducing the risk of an HMRC enquiry.
