Year-End Closing Deadline Approaching: A Step-by-Step Guide

Year-end closing puts every accounting department under pressure. The team works extended hours to hit deadlines on annual wage statements, VAT returns, and corporate tax filings. As the founder or CFO of a Swiss SME, you carry responsibility for financial statements that present a true and fair view to your board and investors. Those same statements form the basis for your annual corporate tax filing in Switzerland.

Work through the steps below before the calendar year closes.

👇YEAR-END ACCOUNTING CHECKLIST👇

The guidelines below help you set up, plan, and execute year-end closing in a controlled, efficient way.

1. Set Up a Closing Schedule

Start by listing every item that appears on your draft balance sheet and P&L. That means:

• Asset and liability line items from the draft balance sheet.
• Revenue and expense categories from the draft P&L.
• Accounting regulations applicable to your entity type and size.

Once you have the list, assign tasks to owners, attach deadlines, and delegate wherever the work allows it. Run the schedule past your team so they can flag gaps or ask questions early, before the crunch begins.

2. Start Early Enough

The single most effective thing you can do is send information requests before anyone thinks they need to. Issue emails to all relevant parties at least one month before year-end, then follow up every ten days until you have what you need. Be specific about what you want and when.

Two key groups require coordinated outreach:

• Sales team: Confirm all invoicing is complete for projects and services delivered by 31 December. Get a precise figure for unbilled revenue as at that date. Ask for a status update on overdue debtors, with notes on actions taken and any recommendations for write-offs or bad-debt provisions.
• Department heads and staff: All purchase and expense invoices for the year must reach the accounts team within five to ten days of year-end. Reimbursement claims tied to personal or business cards and wallets – travel, phone, and similar – need to be submitted with payment proof and receipts within the same window.

This approach moves the bulk of information gathering into the final month, freeing your team to focus on finalisation rather than chasing.

3. Collate Third-Party Statements

Collect external statements as at the last day of the year. The list typically includes:

• Bank statements for every account, wallet, and credit card the company uses: PostFinance, Revolut, Stripe, PayPal, and any others.
• Investment statements for equity, debt, mutual funds, or crypto positions held on the balance sheet. You need these to calculate fair value at year-end and record fair value gains or losses for the period.
• Balance confirmations from counterparties. Write to key suppliers and customers to validate the receivables and payables figures in your own books as at the final day.
• Active resolution of open issues with management, auditors, and colleagues. Don't let pending queries drift into the new year.

4. Standard Operating Procedures, Checklists, and Templates

Build standard operating procedures, detailed checklists, and working templates that fit your business specifically. These tools let your team execute quickly and correctly without missing steps or relying on institutional memory.

5. Complete the Accounting Entries for the Year

With all the collected information in hand, post every transaction for the year: sales invoices, purchase invoices, expense claims, cash movements, bank transactions, and credit card entries. The goal is a complete, clean ledger before you move to review.

6. Review Draft P&L

Work through your draft P&L systematically. For each category below, check whether an adjustment entry is required.

• Revenue: Confirm that recognition follows the contract terms and applicable accounting rules. Post entries for deferred revenue and unbilled revenue where needed.
• Other income: Verify interest income, dividend income, and any gain or loss on investment sales, plus fair value movements.
• Purchases: Confirm every purchase invoice for the year has been posted, and reconcile input VAT in your books against the VAT returns filed.
• Closing stock: Carry out a physical stock count and reconcile the result against your cost records.
• Personnel expenses: Salaries, wages, bonuses, AHV/BVG contributions, health insurance, accident insurance, and related items should all be posted and reconciled with the annual wage statements.
• Product development expenses: Determine whether these qualify as revenue expenditure or capitalised development costs under the applicable accounting framework.
• Sales and marketing expenses: Include all costs, including prepaid advertising commitments.
• Legal, tax, and financial consulting fees: Accrue for any invoices not yet received but covered by agreements in place.
• Rent, insurance, energy, telecommunications, and other overhead: Accrue based on the most recent invoice or a monthly average.
• Depreciation: Calculate and post depreciation for all fixed assets based on their estimated useful lives.
• Amortisation: Calculate and post amortisation for intangible assets on the same basis.
• Interest: Check loan agreements and post accrued interest to the correct period.
• Current tax: Prepare your tax computation, review it, and post the provision for corporate tax.

7. Review Draft Balance Sheet

Once the P&L entries are complete, move to the balance sheet. Cross-check each material line item and pass adjustment entries where the review identifies a gap.

• Bank balances: Compare the balance per bank statement with the balance in your books, and prepare bank reconciliation statements for any differences.
• Accounts receivable: Review the aged receivables report and assess which balances require a provision for bad or doubtful debts.
• Fixed assets register: Post all additions, disposals, and depreciation charges for the year, then confirm the register balance ties to the fixed asset schedule.
• Investments: Confirm the carrying value in your books matches the statements received from brokers, funds, or companies.
• Input VAT credits and refunds due: Reconcile against the VAT returns or income tax filings.
• Prepayments: Work through the prepaid expense schedule and confirm it agrees to the balance sheet line.
• Accounts payable: Review the aged payables report and make any adjustments required.
• Deferred revenue: Confirm the balance sheet figure agrees to the deferred revenue schedule.
• Loans: Validate the outstanding balance for each loan against the statement from the lender.

8. Lock the Year in Your System

When all entries are posted and the numbers are final, lock the period in your accounting system. This prevents any accidental postings to the closed year by other users or automated processes.

9. Back Up

A complete, verified backup of your accounting data is not optional. Maintain both a local backup and a cloud-based copy. Check that the backup actually completed and that the files are readable before you close the year.

10. Update Opening Balance

Run the year-end carry-forward process in your accounting system to push the closing balances into the new financial year as opening balances. Confirm the figures agree before your team starts posting in the new period.

Frequently Asked Questions

What should Swiss SMEs know about year-end accounting closing?

Year-end closing requires accounting teams to reconcile every balance sheet and P&L line, post adjustment entries, lock the period in the system, and produce financial statements that satisfy both Swiss GAAP requirements and the corporate tax filing. Starting at least a month before 31 December and using a structured checklist keeps the process on track and reduces errors.
