Year-End Closing: 25 Controls to Complete Before You Issue Financial Statements

Year-End Closing: 25 Controls to Complete Before You Issue Financial Statements

This checklist is for finance managers and accountants responsible for closing the year, who want statements that are both reliable and defensible on audit. The order below is the one I follow in company files; run with discipline, it resolves most audit findings before the statements are even drafted.

Closing does not begin in the last month

The common mistake is deferring the close to the new year. Balance confirmations, stocktake planning, petty cash settlement and suspense account clean-up should begin two to three months before year end. What remains afterwards should be posting adjustments, not gathering information.

Cash, banks and receivables

  1. Prepare bank reconciliations for every account and schedule the open items — unpresented cheques and deposits in transit listed separately.
  2. Split receivable cheques into matured, in collection and returned, and move aged returned cheques into receivables.
  3. Settle petty cash floats; the year-end balance should be nil or confirmed by a cash count.
  4. Obtain balance confirmations from major customers and suppliers and clear differences before closing.
  5. Compute the doubtful debt provision from an aged receivables analysis. For tax deductibility, the debtor details, amount, collection history and grounds for doubt must be documented.
  6. Clear suspense and inter-branch accounts to nil. A residual balance here is a reliable signal of weak internal control.

Inventory and fixed assets

  1. Complete the stocktake and post variance adjustments; the procedure is in the year-end inventory count article.
  2. Value inventory at the lower of cost and net realisable value, recognising write-downs for obsolete and expired lines.
  3. Perform a fixed asset verification; derecognise scrapped, missing or sold assets.
  4. Compute depreciation using the rates and lives in the statutory depreciation schedule; the in-service date of each asset must be evidenced.
  5. Review assets under construction; completed projects must transfer to fixed assets so depreciation begins.

Liabilities, provisions and commitments

  1. Calculate the end-of-service benefit provision per employee, conventionally one month of final salary and regular allowances per year of service.
  2. Accrue incurred but unpaid expenses — utilities, rent, professional fees. Omitting this inflates reported profit artificially.
  3. Allocate prepayments and advances received to the correct period; rent or insurance covering next year is not this year's cost.
  4. Retranslate monetary foreign currency items at the year-end reference rate and keep translation gains and losses separate; the accounting and tax treatments differ and this is a frequent source of dispute.
  5. Review contingent liabilities and litigation with legal counsel and provide or disclose as appropriate.

Tax and payroll matching

  1. Sales matching: ledger sales must agree with invoices filed to the taxpayer portal and with the VAT returns, with any difference documented.
  2. Purchase and sales matching against the quarterly transaction reports — one of the first extracts an assessor runs.
  3. Payroll matching: payroll cost in the ledgers against payroll tax filings and social security lists; all three should reconcile.
  4. Segregate non-deductible expenses: undocumented costs, fines, cash payments above the prescribed ceiling and personal expenses. Add them back yourself in the tax computation.
  5. Record the current tax provision at the 25 percent Article 105 rate on estimated taxable income, carrying withholding and advance payments as an asset.

Equity and final closing

  1. Review shareholder and director current accounts; undocumented drawings can be recharacterised as income on audit.
  2. Appropriate the legal reserve: one twentieth of net profit annually until the reserve reaches one tenth of share capital.
  3. Close temporary accounts to the income summary and transfer the result to retained earnings; all revenue and expense accounts should then be nil.
  4. Produce the closing trial balance, record it in the statutory books, and open next year from it.

Have next year's statutory books sealed before the new fiscal year begins. Late sealing exposes the books to challenge — see the statutory books article.

Adjustments that are most often skipped

Adjustment Effect on profit Risk if omitted
Fixed asset depreciation Decrease Understated cost, higher tax
End-of-service provision Decrease Hidden obligation, social security dispute
Accrued unpaid expenses Decrease Artificial profit, fictitious dividends
Inventory write-down Decrease Overstated assets
Advances treated as revenue Wrongly increases Premature revenue recognition
Add-back of non-deductible costs Raises tax base Assessment notice with penalties

Keep an "adjustments working paper" recording every entry, its amount, supporting document and approver. Next year it is the fastest way to answer both the auditor and the assessor.

After the close

Action Deadline
Sign the financial statements Before the general meeting
Hold the annual ordinary general meeting Within 4 months of fiscal year end
File the corporate income tax return By 31 Tir for a year ending in Esfand
File the individual business return By 31 Khordad
File quarterly transaction reports Within one and a half months of quarter end

Filing mechanics and common errors are covered in the corporate tax return article.

Key takeaways

  • Closing is a multi-month process; the final weeks are for posting adjustments, not collecting data.
  • Three-way matching of ledger sales, portal invoices and VAT returns is the key year-end tax control.
  • Do not drop accruals and provisions; artificial profit costs tax and invites fictitious distributions.
  • Identify and add back non-deductible costs yourself rather than being surprised on audit.
  • A signed adjustments working paper is the best defence in next year's audit.

Frequently asked questions

When should year-end closing start?
Two to three months before the fiscal year end. Balance confirmations from customers and suppliers, stocktake planning and clearing suspense accounts either do not happen at all or happen badly if they are left until the new year begins.
How is the end-of-service benefit provision measured?
The conventional basis is one month of final salary and regular allowances for each year of service, computed per employee. For the cost to be deductible in taxable income, the statutory conditions must be met and the per-employee calculation must be documented.
Which reconciliations matter most before issuing statements?
Sales per the ledgers against VAT returns and invoices filed in the taxpayer system, purchases and sales against the quarterly transaction reports, and payroll cost per the ledgers against payroll tax and social security filings. Differences across these three are the most common audit starting point.
How is the legal reserve calculated?
Under the Commercial Code, companies must set aside one twentieth of annual net profit as a legal reserve until the reserve reaches one tenth of share capital. Beyond that ceiling, further appropriation is optional.
