Preparing Advance Tax and Tax Depreciation Workings

Estimate income for the relevant year using actual results to date and a supportable forecast. Record adjustments, eligible losses, concessions and applicable tax treatment. Review the estimate when sales, margins, significant expenditure or business conditions change.

Calculate the instalment under the current statutory schedule and reconcile supported withholding credits and prior payments. Use the correct period for each item. A credit belonging to another year, or an unmatched certificate, should not be included simply to reduce the payment.

For illustration, if a reviewed annual liability is NPR 600,000, supported payments and credits already accounted for are NPR 200,000, the remaining annual balance is NPR 400,000. That subtraction does not decide the current instalment. The timing rule, required cumulative amount and treatment of the credits still need to be applied.

Prepare opening tax balances, additions, disposals and adjustments by the applicable asset category or pool. Retain invoices, dates, business use and disposal evidence. Check the current rules for rates, timing and special treatment before calculating the deduction.

In the income reconciliation, identify accounting depreciation added back and the tax deduction separately. If accounting depreciation is NPR 100,000 and permitted tax depreciation is NPR 120,000 in a simplified example, the net adjustment decreases accounting profit by NPR 20,000. That result depends on the two amounts being correctly established; it is not a universal tax allowance.

Match additions and disposals to the asset register and ledger. Review repairs, improvements, private use and proceeds rather than assigning all expenditure to one category automatically. Keep the assumptions and unresolved classification issues visible.

At year-end, compare the latest forecast, filed instalment workings, payment receipts and final return. Explain differences so the next period starts from reliable balances. A calculator should reproduce a reviewed working; it should not determine an asset’s legal category or invent an unsupported credit.

When a business buys a machine, keep the purchase, tax depreciation and advance-tax forecast connected without merging their purposes. Record the machine in the asset file with its cost, business-use facts and date. Determine the relevant tax pool and permitted timing before carrying its tax deduction into the annual forecast.

If the accounts expense an improvement that should be capitalised for tax, the reconciliation must show the expense adjustment and the correct pool treatment. Merely adding the amount to the pool without reversing the expense can claim the same cost twice. The same problem arises when disposal proceeds are omitted from a pool after the accounting asset has been removed.

For each instalment, retain the annual estimate used on that date, the cumulative liability required by the applicable schedule and the supported credits already taken into account. A payment made after the instalment date should not be used to rewrite the evidence of what was payable at that date.

Compare the final return with each forecast and explain material differences: new assets, disposals, changes in margin, loss claims or a concession no longer available. This comparison improves the next year’s forecast and gives a reviewer a clear reason for the payment sequence. Keep rate-specific and special-depreciation questions with their exact annual source rather than a permanent spreadsheet label.
