Period-end procedures: counts, reconciliations and a closing checklist

A year-end closing checklist for companies keeping balance-sheet books: counts, reconciliations, valuation entries, accruals and checks before the return.

The corporate tax return is filed in April, but the foundation of a correct return is laid on 31 December. This article presents the year-end closing as a checklist in calendar order.

In December: preparation

  • Has the list of fixed assets bought and sold during the year been updated?
  • Have old unpaid or uncollected invoices been sorted out?
  • Have the count day, the count team and the count form been set?
  • Has the opening certification of next year's books or the e-Ledger certificate schedule been planned?

31 December: counts

Cash count. The cash actually in the till is compared with the recorded cash balance. If the records show a high cash balance but there is no money in the till, this may be treated like a loan to a shareholder and carries tax risk.

Stock count. Quantities of goods, raw materials, work in progress and finished goods are counted; the count record is signed. Valuation is made with the chosen cost method: Inventory valuation

Fixed asset count. Fixed assets that are recorded but no longer exist or are unusable are identified; disposal is documented.

Reconciliations

Reconciliation How
Bank Each account's year-end statement is compared with the books
Customers and suppliers A written confirmation letter for significant accounts
Credit cards Comparing statements with the records
Shareholder current account Balance and interest calculation: Shareholder current account
SGK and tax Taxes and SGK debts payable and accruals

Differences found in reconciliations should be resolved before the closing entries.

Valuation and adjustment entries

  1. FX revaluation: foreign-currency cash, bank accounts, receivables and payables are valued at the CBRT foreign exchange buying rate: FX revaluation · Period-end rates
  2. Rediscount: rediscount can be applied to receivables and payables in the form of notes: Rediscount
  3. Depreciation: annual depreciation is recorded: Depreciation methods
  4. Doubtful receivables: a provision is made for receivables in litigation or enforcement: Doubtful and worthless receivables
  5. Accruals: expenses incurred by year end but not yet invoiced (rent, electricity, interest) and prepayments relating to future years are separated.
  6. Severance pay: for tax purposes the provision cannot be expensed; in the commercial balance sheet it can be calculated under TFRS.
