Good Records Make Tax Filing Straightforward

Most small company directors don't dread tax because the rules are impossible. They dread it because the paperwork arrives in a shoebox, a carrier bag or a folder of unopened emails. When your records are tidy, filing becomes a short administrative task rather than a panicked scramble. When they aren't, you pay for it twice — once in accountancy fees to untangle the mess, and sometimes again in penalties.

The good news is that record-keeping for a UK limited company is not complicated once you know what HMRC and Companies House expect. Set up a simple routine, stick to it monthly, and you will rarely be caught out.

Which Records You Need to Keep

As a limited company, you are legally required to keep adequate accounting records. In practice, that means capturing everything that supports the numbers in your accounts and tax returns. At a minimum, keep:

• Sales records: invoices issued, credit notes, till rolls, and bank statements showing money coming in.
• Purchase records: supplier invoices, receipts, and contracts for goods and services.
• Expense receipts: fuel, travel, subsistence, software subscriptions, and anything you intend to claim as a business cost.
• Payroll records: contracts, payslips, starter and leaver checklists, and pension contribution details.
• Bank and credit card statements for every company account, reconciled against your bookkeeping.
• Asset records: what you bought, when, and how much — needed for capital allowances and depreciation calculations.
• Statutory documents: the register of members, minutes of director decisions, and share allotment paperwork.

You need to keep company accounting records for six years from the end of the accounting period they relate to. VAT records also carry a six-year retention requirement, and payroll records should be kept for at least three years after the tax year they cover. If you are ever unsure, keep it longer — storage is cheap, but reconstructing a missing invoice two years later is not.

The Deadlines Worth Diarising

Deadlines have a habit of clustering around the same busy weeks, so put these in your calendar with reminders a fortnight ahead.

• Corporation Tax payment: normally nine months and one day after the end of your accounting period.
• Company tax return (CT600): due twelve months after the end of the accounting period.
• Annual accounts to Companies House: nine months after your accounting reference date for a private company.
• Confirmation statement: due annually, within fourteen days of the review period ending.
• VAT returns: usually quarterly, with payment and submission one month and seven days after the period ends if you pay by Direct Debit.
• PAYE: reported on or before each payday through Real Time Information, with payment to HMRC by the 22nd of the following month (19th if paying by post).
• P11D and P11D(b): 6 July, for benefits in kind you provide to employees or directors.
• Self Assessment: 31 January for the online return and balancing payment, with payments on account due 31 July.

If your accounting period is longer or shorter than twelve months — common in a first year of trading — check the dates carefully. They won't always fall where you expect.

What Late Filing Actually Costs

Penalties for late accounts at Companies House start at £150 and rise quickly if the delay continues, doubling where a company files late two years in a row. HMRC charges its own penalties for late company tax returns, plus interest on late Corporation Tax and VAT payments. Late PAYE payments attract escalating charges the longer they remain outstanding.

The pattern is consistent: the earlier you act, the cheaper the problem. If you realise you cannot meet a deadline, tell your accountant immediately. There is often a legitimate route to reduce exposure, but only if there is still time to use it.

Practical Habits That Keep You Ahead

You do not need expensive software to stay compliant, though good cloud bookkeeping does help enormously. What matters more is consistency. Try these habits:

• Reconcile monthly. An hour each month beats a lost weekend in January.
• Photograph receipts immediately and file them against the transaction in your accounting software.
• Separate business and personal spending. A dedicated company account saves hours of untangling.
• Keep a deadline calendar shared with whoever handles your finances.
• Review your position quarterly with your accountant, not just at year end.

Why an Accountant Is Worth the Fee

A good accountant does far more than submit forms. They will confirm your accounting reference date, set up your payroll and VAT scheme correctly, flag deadlines before they bite, and spot allowances you might otherwise miss — from the employment allowance to capital allowances on equipment. For many small companies, the tax saved comfortably exceeds the fee.

Choose someone who works with businesses of your size and sector, and who answers questions in plain English. Share your records promptly, ask about anything that looks unfamiliar, and treat the relationship as ongoing rather than an annual transaction. Do that, and tax filing becomes what it should be: a routine piece of admin that quietly keeps your company in good standing.
