How to prepare year-end accounts, with the working papers done for you.

First the method: the preparation of year-end accounts in order, a corporation tax computation worked line by line, and the dates the accounts and the tax are due. Then every screen of PrepIQ, from the client's records to a signed-off set of working papers.

How to prepare year-end accounts.

Preparing year-end accounts is the same job whoever does it: close the books, adjust them, prove them, compute the tax, then produce and file the statutory accounts. Here is the order a practice works in, for a UK limited company. What year-end and statutory accounts are, and who has to file them, is in the PrepIQ FAQ.

  1. Close the books for the yearReconcile every bank account to its statement at the year end, post the last sales and purchase invoices, and clear the suspense account. Bank Reconciler proves the bank against the books, and CodeIQ codes what is left.
  2. Run the trial balanceExport the general ledger and the trial balance at the year end. The trial balance is the closing totals; the ledger lets each figure be traced to the postings underneath it.
  3. Post the year-end adjustmentsAccruals and prepayments, depreciation on the fixed asset register, the stock count, bad and doubtful debts, and the directors' loan account. Each one is a journal with a working paper behind it.
  4. Extend the trial balanceLay the adjustments beside the recorded balances on an extended trial balance, check every column balances, and carry the profit through to the balance sheet.
  5. Compute the taxFor a company, start from the accounting profit, add back what is disallowed, deduct capital allowances and apply the corporation tax rates, as in the worked computation here. For a sole trader, the adjusted profit goes to the self assessment return.
  6. Prepare the statutory accountsPreparing statutory accounts from a reviewed set of working papers means laying the figures out as financial statements under the company's framework (FRS 105 for a micro-entity, FRS 102 Section 1A for a small company), with the notes and statements it requires, usually in your accounts production software (IRIS, TaxCalc, CCH and the like), from the working papers PrepIQ prepares.
  7. Review, approve and fileThe directors approve and sign the accounts, which are filed at Companies House; the company tax return goes to HMRC. The year-end accounts deadlines are in the table below.

A corporation tax computation, step by step

An illustrative company with no associated companies, for a 12-month period. Profits up to £50,000 are taxed at 19% and above £250,000 at 25%; in between, marginal relief at 3/200 brings the effective rate here to 22.75%.

The year-end accounts deadlines

Accounts to Companies House9 months after the end of the accounting period (private company). A company's first accounts are due 21 months after it was incorporated.
Corporation tax paid to HMRC9 months and 1 day after the end of the accounting period, for a company with taxable profits up to £1.5 million; larger companies pay in quarterly instalments.
Company tax return (CT600)12 months after the end of the accounting period.

An Irish company works to Revenue and the CRO instead: 12.5% on trading income and 25% on non-trading income, the close company surcharge, and the CT1 and its balance due on the 23rd of the ninth month after the period end. The Irish year end is set out in full.

Part two · in PrepIQ

The same year end, screen by screen.

PrepIQ prepares steps 3 to 5 of the method, starting from the ledger and trial balance you export at step 2: it reconciles the client's records, builds the schedules and the extended trial balance, and computes the tax, so your time goes on the review and the judgement. It is on the ReconcileIQ practice plans, Practice Essential and above. Each step below names the screens and buttons as they appear in PrepIQ.

  1. Set your firm settings

    Open PrepIQ and expand Firm settings at the top of Start a job. Set these once and every job inherits them. Start with “Jurisdiction”: “United Kingdom (incl. Northern Ireland)” or “Ireland”. It decides which tax rules RiQ follows and which set of working papers you get back, so it is not a label on the front sheet (the UK and Irish rules are set out on the features page). A Northern Ireland company pays UK corporation tax and files a CT600, so a Northern Ireland practice sets United Kingdom.

    The rest decide how the output reads: “Reporting currency”; “Tax computation” (prepare it and post the tax journal, prepare it but post no tax journal, or leave tax to the firm entirely); “Reporting framework” (FRS 102 Section 1A, FRS 105 for a micro-entity, or full FRS 102); “Client query email”; “Dividends”; “Rounding”; a “Query threshold” above which unexplained differences are flagged for the reviewer; the “Practice name”; and “Anything else, in your own words”. Press Save settings.

    Tip. If you compute and file tax in your own software, choose one of the last two tax computation options. With “Prepare it, but post no tax journal” you still get the computation and the workings, and the papers say the firm posts the tax elsewhere.

  2. Start a job

    Under Start a job, enter the “Client” and choose the “Entity”: “Sole trader” or “Limited company”. It is not cosmetic: it selects the template and the rules, and both the accounting and the tax treatment follow from it. A sole trader's trade, property and savings income is kept in its right place for self assessment, with drawings, capital introduced and private-use restrictions handled. A limited company keeps its directors' loan accounts separate, takes dividends against reserves, and has its corporation tax computed.

    “Jurisdiction” is taken from your firm settings; change it here if this one client is somewhere else, and only that job moves. A job is stamped with its jurisdiction when you upload, so changing your settings later cannot disturb a job already running. Use “Anything RiQ should know” for anything not in a document.

  3. Upload the records

    Drop the client's bookkeeping and supporting documents on The client's records: the ledger from Xero, QuickBooks, Sage, Pandle, or any general ledger as CSV or Excel, with the trial balance beside it. Any format works: spreadsheets, CSV, PDFs, scanned or photographed paperwork, and the client's own emails explaining odd items, which are read as evidence like anything else. Up to 30 files, each up to 50MB. Open What to send for the best result, PrepIQ's year-end accounts checklist: a full-year transactions or general ledger export and the trial balance (CSV or Excel, not Apple Numbers), bank statements for the whole year including second accounts such as Wise, PayPal or Stripe, aged debtors and creditors, finance agreements (HP, loans, mortgages and completion statements), payroll (P11s, P32 and P60s), VAT returns, and a note on anything unusual.

    Two optional boxes sit below. “Last year's working papers” lets RiQ carry the balances forward (leave it empty for a brand-new client). “Your working-papers template” makes RiQ prepare into your firm's own template, so the set carries your layout, sheet order and labels; leave it empty to use the built-in PrepIQ template. Both take a real Excel workbook (.xlsx or .xls).

    Tip. The ledger matters as much as the trial balance. A trial balance is a set of closing totals; the general ledger is what lets every figure be traced to the postings underneath it.

  4. Choose the depth and hand it to RiQ

    Under Preparation depth, choose “RiQ default” (5,000 credits), RiQ's standard preparation and right for most jobs, or “RiQ maximum” (10,000 credits), its deepest reasoning for complex, messy or high-stakes year-ends. Then press Hand it to RiQ. The credits come out of your practice plan's allowance.

    You can have two jobs open at once, from upload until you press Finish, and the job list shows how many slots are free. If both are in use, Finish a job first opens: sign off a finished set and finish it to free a slot.

    Hand it to RiQ
  5. Follow the job

    The job appears under Your jobs, with three counts across the top: “With RiQ”, “For you” and “Finished”. Its status moves from “In RiQ's queue” to “RiQ is preparing the papers”, while it reconciles the sources and builds the schedules, and the card shows the stages as they pass and RiQ's live updates beneath them.

    RiQ reconciles every source it has, builds the schedules, posts them to an extended trial balance with each figure linked back to the sheet it came from, recalculates the set end to end and checks that it balances. Nothing is plugged to force a balance. If it cannot complete something, the status reads “Needs your attention”, with notes on what it could not finish.

    Illustrative: the card names each stage as RiQ reaches it.

  6. Review the set

    When the status reads “Ready for your review”, press Download for the workbook. Read it like a junior's file. At its heart is the extended trial balance: opening balances, recorded, unrecorded and adjustment columns, all footing and balancing, with profit carried through to the balance sheet. Behind it sit the schedules: records summary, fixed assets and depreciation, capital allowances (feeding only the tax computation), one finance reconciliation per agreement, VAT reconciled to the returns, and the tax computation. Every posted figure is linked to its working sheet, and any figure typed in is labelled with its source.

    RiQ's notes opens RiQ's working notes: every posting, assumption, judgement and query, so your review starts from a trail. Where a treatment needs your call or the client's confirmation, it is marked TBC and raised as a query, never decided silently. Client email shows the draft query email to the client, when there are client questions; Copy to clipboard or Download .txt.

    Tip. The queries go on the query register whatever you choose for the client email; the email setting only decides whether a draft is written for the client.

  7. Ask RiQ for changes

    Anything you want done differently goes back through Ask RiQ. Write it in plain English under “Ask RiQ to make a change”, attach anything the client sent late under “Add documents” (optional), and press Send to RiQ. It reworks the same set with the full context of what it already did, rather than starting again; the status reads “RiQ is applying your changes” while it works.

    The confirmation says what it costs before anything is charged: each revision is a full re-pass, 1,250 credits on a RiQ default job or 2,500 on a RiQ maximum job.

  8. Sign off and finish

    When the file is right, press Sign off. The confirmation reads “Sign off this job? This records your approval.” and the status becomes “Signed off”. The papers are prepared for your review and your sign-off; nothing is filed on your behalf, and no judgement in them is final until you have made it.

    Download what you need, then press Finish and confirm with Finish job: it wraps up and clears the working files: the client documents are deleted from our servers, and the job moves to the archive. Anything you have already downloaded is unaffected. Finishing also frees a slot for a new job.

    Tip. For a client kept in IQ Books, finish only after the adjusting journals are in the ledger. If they are not, PrepIQ warns you (“Journals not in the ledger yet”) before it lets you finish anyway.

From IQ Books, with no export.

If the client's books are kept in IQ Books, there is nothing to export, and the adjusting journals come back into the ledger.

In IQ Books, open Accounting, then Year-end close. Step 1 · Prepare sets the financial year and the period start (for a first, short or extended period), the number of associated companies (it sets the corporation tax thresholds), your instructions for the year and the client's correspondence, who prepared it, the supporting records (up to 26 files), last year's signed-off papers, your template, and the Preparation depth. Press Prepare with PrepIQ: the period general ledger and the closing trial balance are generated from the ledger for you.

When the job is ready, Step 2 · Bring the adjustments in lists its adjusting journals. Review them, tick the ones to post and press Post the ticked journals; nothing posts until you confirm. Each posts as an adjustment carrying a PrepIQ badge. Step 3 · Close and lock then closes the year.

Next year, continuing clients

Give PrepIQ last year's working papers and it continues from them rather than starting blank.

  • Last year's closing balance sheet becomes this year's opening balances, proven to tie exactly; the profit and loss starts at nil.
  • The fixed asset, capital allowance and finance schedules carry their brought-forward figures, so depreciation and the pools pick up where they left off.
  • Because it works from your prior file, your layout, labels and presentation carry from year to year.

Without a prior file it treats the client as new and opens at nil, which is right for a first period but not for a continuing one.

Where PrepIQ sits in the year

PrepIQ works from a ledger, and the cleaner that ledger is when it arrives, the less of the set comes back queried.

  • Bank Reconciler proves the bank against the books first.
  • CodeIQ codes the year's transactions and posts them to the client's books.
  • LedgerIQ takes the same ledger the other way, into management accounts and ratio analysis for a client meeting.

Questions

Before you start.

Short answers to what people ask before their first year end in PrepIQ. The PrepIQ FAQ has more.

How do you prepare year end accounts?

Close the books for the year, run the trial balance, post the year-end adjustments (accruals, prepayments, depreciation, stock and bad debts), extend the trial balance, compute the tax, then prepare the statutory accounts in the right format and have the directors approve them before filing. The method above takes each step in turn; PrepIQ prepares the working papers for steps 3 to 5, starting from the ledger and trial balance you export at step 2.

How do you prepare statutory accounts?

From a reviewed set of working papers: the extended trial balance gives the figures for the balance sheet and profit and loss, which are laid out under the company's framework (FRS 105 for a micro-entity, FRS 102 Section 1A for a small company) with the notes and the statements the framework requires, then approved by the directors and filed at Companies House. PrepIQ prepares the working papers behind them; the statutory accounts themselves are produced in your accounts production software.

How is corporation tax calculated on company profits?

Corporation tax is calculated on taxable profit, not turnover. Start from the accounting profit, add back what the tax rules disallow (depreciation, client entertaining), deduct capital allowances, and apply the rates for the financial year: 19% on profits up to £50,000, 25% above £250,000, and 25% less marginal relief in between (the limits are reduced for short periods and associated companies). The worked computation above shows each line.

What does PrepIQ need from the client?

The full-year general ledger export and trial balance, bank statements for every account, aged debtors and creditors, finance agreements, payroll and VAT returns where they apply, last year's working papers for a continuing client, and a note on anything unusual. Any format works, up to 30 files of 50MB each.

How much does a PrepIQ job cost?

A year-end job draws 5,000 credits on RiQ default or 10,000 on RiQ maximum, and each Ask RiQ revision 1,250 or 2,500. PrepIQ is on the ReconcileIQ practice plans, Practice Essential and above, and the credits come out of the plan's allowance.

Can PrepIQ post the adjusting journals into IQ Books?

Yes, for clients kept in IQ Books. Start the job from Accounting, Year-end close, and when it is ready its adjusting journals appear in step 2 for you to review line by line before anything posts. For any other platform they come back in the workbook, on its Journals sheet and in the extended trial balance's adjustment columns, for you to post there.

Run your next year end.

PrepIQ is on the ReconcileIQ practice plans, Practice Essential and above. A job draws 5,000 credits on RiQ default or 10,000 on RiQ maximum, from the plan's allowance.
