Overview
This guide walks UK finance teams through the Business Central year-end close, from early preparation to new year set-up. It covers sandbox rehearsal, adjustments, posting restrictions, audit support and the mistakes to avoid.
Key Takeaways
- Rehearse the full close in a sandbox, because Microsoft warns that you cannot reopen a fiscal year after you close it.
- Create the next fiscal year before the old one ends, so your team can keep posting without delay.
- Adjust inventory costs, post depreciation, revalue foreign currency balances and settle VAT before you close the year.
- Restrict posting dates in General Ledger Setup before you close, then give named users a wider range in User Setup.
- Rerun the Close Income Statement batch job after every late posting to a closed year.
- Plan for GOV.UK deadlines, because Companies House accounts fall due nine months after your year-end.
The Year-End Close at a Glance
A Business Central year-end close follows a set order. You finish your adjustments, lock posting dates and close the fiscal year. After that, you close the income statement. The table below shows each step and where to find it.
| Step | Where to find it | What it does |
|---|---|---|
| 1. Rehearse in a sandbox | Business Central admin centre | Tests your full process on a copy of live data |
| 2. Add the next fiscal year | Accounting Periods | Creates the periods for the new year |
| 3. Adjust inventory | Adjust Cost – Item Entries and Post Inventory Cost to G/L | Brings stock values into the ledger |
| 4. Post depreciation | Calculate Depreciation | Charges the final period to the ledger |
| 5. Revalue currency | Adjust Exchange Rates | Posts unrealised gains and losses |
| 6. Settle VAT | Calc. and Post VAT Settlement | Clears VAT entries to the settlement account |
| 7. Restrict posting dates | General Ledger Setup and User Setup | Stops unwanted postings to the old year |
| 8. Close the fiscal year | Accounting Periods, Close Year | Marks the year’s periods as closed |
| 9. Close the income statement | Close Income Statement | Moves the year’s result to retained earnings |
| 10. Set up the new year | Number series, budgets and recurring journals | Prepares the new year for posting |
Treat this order as a baseline, because your setup may add steps. For example, groups need intercompany and consolidation checks. Manufacturers need work in progress reviews.
Prepare Your Business Central Year-End Close
Preparation decides how smoothly the close runs. Start four to six weeks before your year-end date, so you have time to fix problems. Name one owner for the close and set a due date for every task.
Add the Next Fiscal Year Early
Add the next fiscal year before the old one ends. Open Accounting Periods and run the Create Fiscal Year batch job. Enter your start date, the number of periods and the period length, which is usually one month.
Next, check that the first period has the New Fiscal Year box ticked. The batch job sets this flag automatically, and you only tick it yourself if you create periods manually. Business Central uses the flag to decide which periods to close at year-end, as Microsoft’s guidance on accounting periods explains. Check the period dates against your calendar too, because errors here carry into every report.
Rehearse in a Sandbox
You cannot reopen a fiscal year once you close it, so a rehearsal protects you. Ask your administrator to copy production into a sandbox, using the Copy action in the Business Central admin centre. Microsoft describes the steps on its environment copy page. After that, run every step in this checklist on the copy.
Time each step and record every error message, because those notes shape your production plan. Compare the sandbox trial balance with the figures you expect. Switch off integrations and job queues in the sandbox, because Microsoft lists precautions for sandboxes that hold production data.
Finish Your Month-End Routines
Complete your last month-end close before you start year-end work. Reconcile bank accounts, post recurring journals, and review accruals and prepayments. Our guide to speeding up month-end close in Business Central covers these routines in detail.
Year-End Adjustments for Inventory, Fixed Assets, Currency and VAT
Adjustments make sure your ledger shows the true position at year-end. Work through the four areas below, because each one can change your profit figure.
Inventory
Inventory often carries the largest year-end adjustment. Run the Adjust Cost – Item Entries batch job first, so costs reach every outbound entry. After that, run Post Inventory Cost to G/L. Check that the posting period is open in General Ledger Setup.
Next, open the Inventory – G/L Reconciliation page to compare stock values with your ledger. Post your physical stock count. Write down obsolete items using our approach to managing obsolete and slow-moving stock.
Finally, run the Close Inventory Period – Test report. Close the inventory period when it shows no problems.
Manufacturers should also review work in progress and goods received not invoiced. See how Business Central supports Manufacturing and Engineering and Distribution and Wholesale businesses.
Fixed Assets
Post all acquisitions and disposals first. After that, run the Calculate Depreciation batch job for the final period. Review the lines in the fixed asset journal before you post them. Compare the fixed asset register with your balance sheet accounts after you post, because gaps show up quickly.
If you claim capital allowances, check that your tax depreciation book includes your latest additions. This keeps your accounting and tax records consistent, which makes the Company Tax Return easier.
Foreign Currency
Enter your year-end exchange rates first. Once they are in, run the Adjust Exchange Rates batch job with the posting date set to your year-end date. It revalues open customer, vendor and bank balances in foreign currencies and posts unrealised gains and losses. Review the largest balances by hand, because a wrong rate affects every line.
VAT
Reconcile your VAT accounts to your final VAT return of the year. Once they agree, run the Calc. and Post VAT Settlement batch job to move the balance to your settlement account. Check that no VAT entries stay open when you have already filed the period.
If you use partial exemption or the annual accounting scheme, complete those year-end calculations too. Your accountant can confirm which ones apply.
Restrict Posting Dates Before You Close the Year
Closing a fiscal year does not stop postings. Microsoft confirms that you can still post general ledger entries to a closed year, as its closing the books guide explains. So you must restrict posting dates yourself. Do it before you close the year, so nobody posts into the old year during the close.
Open General Ledger Setup and set Allow Posting From and Allow Posting To to the new year only. Next, open User Setup and give your close team a range that covers the old year. Business Central applies a user’s dates instead of the company-wide range. This lets your close team post the closing journal while it blocks everyone else.
Close the Year and Handle Late Adjustments
Once your adjustments are complete, open Accounting Periods and choose Close Year. After that, run the Close Income Statement batch job and post the journal it creates. Rehearse both steps in your sandbox first, because the year cannot reopen.
Handle Late Adjustments Safely
Auditors and tax advisers sometimes find issues after you close. Follow this process, so you keep control and a clear record.
- Get written approval from your finance director for each late entry.
- Give one named user a wider posting range in User Setup for a short time.
- Post the adjustment with a clear description and a distinct document number, such as one that starts with AUD.
- Run the Close Income Statement batch job again, and post the new closing journal.
- Restore the original posting range, and record when you did it.
You can run the Close Income Statement batch job several times, according to Microsoft, so this process is safe to repeat.
Audit Support, Filing Deadlines and New Year Set-Up
Give Auditors a Clear Trail
Auditors want a clear trail from the accounts back to source documents. Business Central supports that trail through drill-down from reports to ledger entries and posted documents. Export your trial balance as at the year-end date, and keep a copy with your working papers.
Turn on the change log for sensitive setup tables before next year, so you can show who changed what and when. Avoid date compression until the audit ends, because it removes detail from posted entries.
Plan around UK Filing Deadlines
UK deadlines arrive quickly after year-end. According to GOV.UK, private limited companies must file annual accounts with Companies House nine months after the financial year ends. Most SMEs must pay Corporation Tax nine months and one day after the accounting period ends. The Company Tax Return follows at 12 months.
Add these dates to your close calendar, so your audit timetable works backwards from them. Our Power BI for Business Central page shows how to build reporting packs that your directors can read quickly. Looking ahead, our guide to the UK e-invoicing mandate explains how finance processes will change further.
Set Up the New Year
Set up the new year as soon as the closing journal posts. Work through this list:
- Confirm that the new fiscal year exists and that its periods match your calendar.
- Add number series lines with the new starting date, so document numbers continue correctly.
- Update recurring journals when dates or amounts change.
- Load budgets for the new year, so reports show variances from day one.
- Review depreciation books, VAT settings and exchange rate tables.
- Check that retained earnings and opening balances agree with your signed accounts.
Finally, schedule your key reports for the new year. Our post on financial report scheduling shows how.
Common Year-End Close Mistakes
Most year-end problems come from a few repeat mistakes. Check your plan against this list.
- Closing the fiscal year too early. A closed year cannot reopen, so finish every adjustment first.
- Skipping the sandbox rehearsal. Errors that surface in production cost far more time than errors you find in a copy.
- Posting inventory costs before adjusting them. Run Adjust Cost – Item Entries first, or your stock values will not match your ledger.
- Leaving posting dates open. Without restrictions before the close, users can post into the old year without anyone noticing.
- Forgetting to rerun Close Income Statement. Late entries leave income statement balances in the old year until you rerun it.
- Missing number series for the new year. Posting then stops with an error, so check your series lines before the first day.
- Running date compression too soon. It removes detail, so your auditors may lose evidence they still need.
- Relying on one person. Document the process, so a colleague can run it if your usual owner is away.
What This Means for Your Finance Team
A tidy year-end close protects your accounts, your audit timetable and your credibility with directors. Business Central gives you the tools, but the order and the controls matter most. Rehearse first, adjust carefully, lock your dates and keep an audit trail.
Small finance teams gain the most from a written checklist. Our Manchester team works with finance directors and managers at UK SMEs, so we know where year-end work stalls.

FAQs
First, finish your adjustments and post all entries for the year. Next, open Accounting Periods and choose Close Year. After that, run the Close Income Statement batch job and post the journal it creates. Rehearse the sequence in a sandbox before you run it in production.
No. Microsoft’s documentation confirms that you cannot reopen a fiscal year once you close it. You can still post entries to the closed year, so restrict posting dates as well. After you post late entries, run the Close Income Statement batch job again.
It creates journal lines that cancel the balance of each income statement account and move the result to retained earnings. You then post the journal manually. The lines carry a closing date, which Business Central shows with a C before the date. You can run the batch job more than once.
Not always. Microsoft says Business Central only requires accounting periods if you want to close the income statement or run data compression. Most UK finance teams close the year anyway, because it gives them a clear year-end position and clean opening balances.
Set Allow Posting From and Allow Posting To in General Ledger Setup. Next, use User Setup to give named users their own date ranges. Business Central applies a user’s dates instead of the company range, so you can allow late adjustments for one person only.
Create it before the old year ends, so your team can post into the new year without delay. Use the Create Fiscal Year batch job on the Accounting Periods page. Check that the first period has New Fiscal Year ticked.
For a private limited company, GOV.UK sets three main dates. Companies House accounts fall due nine months after the financial year ends. Most SMEs must pay Corporation Tax nine months and one day after the accounting period ends. The Company Tax Return falls due 12 months after it ends.
