Outsourced Accounts Preparation

Year-end accounts are high-stakes and low-reward for a busy management team: miss the deadline and penalties are automatic; get the numbers wrong and lenders, HMRC and your own decisions suffer. Our outsourced year-end accounts preparation service takes the whole job off your desk — statutory, management and iXBRL accounts prepared under UK GAAP (FRS 105, FRS 102 including Section 1A) or IFRS, from whatever records you keep, followed by the filings themselves.

For accountancy firms and finance teams, the same service works as white-label capacity: send us the trial balance and working papers, and receive review-ready accounts back to your timetable.

Why Outsource Your Year-End Accounts?

- Cost: pay for accounts production only when you need it, instead of carrying the overhead of in-house expertise used a few weeks a year - Quality: every set of accounts is prepared and reviewed by experienced UK-based staff who do this all day, under current standards — including the FRS 102 revenue and lease changes effective from January 2026 - Certainty: deadline tracking with reminders means the 9-month Companies House window and your tax deadlines are never at risk - No key-person risk: illness or resignation in your finance team no longer threatens your filing calendar - Integration: our tax team prepares the CT600 from the same figures, so accounts and tax return always agree

What the Service Includes

- Statutory accounts under FRS 105, FRS 102 (full or Section 1A) or IFRS, from trial balance or raw records - Filleted or micro-entity filing versions to keep public disclosure minimal where you qualify - Directors' reports and strategic reports where required - Management accounts and year-end packs for boards, lenders and investors - iXBRL tagging and validation for HMRC and Companies House - Corporation tax return (CT600) preparation and submission - Filing at Companies House and HMRC, with confirmations to you

How It Works

1. Handover: we take your records in any state — Xero, Sage, QuickBooks, spreadsheets or a folder of paperwork 2. Review and queries: we reconcile key balances and send you one consolidated query list, not a drip-feed of emails 3. Draft accounts: prepared under the right standard, with the adjustments bookkeeping misses — accruals, prepayments, depreciation, stock and provisions 4. Approval: a clear explanation of the numbers before you sign, including anything that affects tax 5. Filing: iXBRL-tagged accounts to Companies House and HMRC, inside every deadline

Most engagements settle into a rhythm where year two is faster and cheaper than year one, because we tidy the underlying records as we go.

The Deadlines We Protect

- Companies House accounts: 9 months after year end for private companies (21 months from incorporation for first accounts); automatic penalties of £150 to £1,500 for late filing, doubled if late two years running - Corporation tax payment: 9 months and 1 day after the end of the accounting period - Company tax return (CT600): 12 months after the end of the accounting period

We plan preparation backwards from the earliest deadline and keep you informed at every stage — the no-surprises approach that clients value most.
