Nepal's fiscal year runs from 1 Shrawan to 31 Ashadh - roughly mid-July to mid-July in the Gregorian calendar. For Nepali businesses, this is not a configuration setting in software. It is a structural reality that governs tax filing, audit timelines, statutory reporting, and every internal management cycle. A Nepal fiscal year accounting software that treats Shrawan-to-Ashadh as a custom date range rather than a native fiscal structure forces accountants to work around the platform every single month. The cost of that workaround compounds over years into significant lost time and serious compliance risk.
International accounting software was almost universally designed around January-to-December or April-to-March fiscal years. When Nepali businesses install these platforms, the Shrawan-to-Ashadh year is implemented as a non-standard fiscal period - a workaround that propagates through every date field, every report, and every calendar comparison. Bikram Sambat dates rarely appear in the system at all, which means a CA verifying a journal entry against a hand-stamped vendor bill is constantly converting between two calendars in her head.
This article walks through what proper Nepal fiscal year support looks like in accounting software, why BS-AD dual calendar matters at the transaction level rather than just the report level, what year-end closing procedures should produce in a Nepal-context ERP, and the compliance risk that emerges when these basics are not handled natively.
Dual Calendar at the Transaction Level - Not Just on Reports
The first test of whether a platform genuinely supports Nepal's fiscal year is where the Bikram Sambat date appears. In weak implementations, BS shows up only on the final printed report - the underlying transaction stores a single AD date and the BS column is a display conversion. This breaks at the edges. Half of Nepali vendor bills are dated in BS, half in AD, and many in both. An accountant entering a bill needs to capture whatever the source document shows, not a conversion someone might dispute later during audit. Genuine dual-calendar support stores both BS and AD on every transaction and lets the user enter either one, with the other auto-converted and visible alongside it. This is the structural test that separates Nepal-built software from Nepal-localized software.
Shrawan-to-Ashadh as the Native Fiscal Year
The fiscal year setting affects far more than the year-end date. Period comparisons - this Q1 vs last Q1, current half-year vs prior half-year - are only meaningful when the fiscal year boundaries are correct. Trimester reporting under IRD VAT regulations works only when the system recognises that Nepal's trimesters are four-month periods rather than three-month quarters: Shrawan-Kartik, Mangsir-Falgun, Chaitra-Ashadh. A platform that defaults to calendar quarters and asks the user to override produces the wrong reports until someone catches the mistake.
Nepal's fiscal year runs 1 Shrawan to 31 Ashadh, approximately 16 July to 15 July. IRD VAT filing depends on annual turnover - businesses above Rs 1 crore file monthly, those below file by trimester. The trimesters are not calendar quarters - they are four-month statutory periods (Shrawan-Kartik, Mangsir-Falgun, Chaitra-Ashadh). Accounting software that gets either of these wrong will produce filings that do not reconcile with IRD records.
Period Locking and Year-End Closing
Once a fiscal year is closed, no entries should be possible in that period without an authorised reopen action. This is the basic financial control that lets a CA sign off on a Balance Sheet knowing the underlying period cannot be silently modified afterward. The closing procedure inside a proper Nepal-context ERP runs in a defined order: post final adjusting entries, reconcile bank statements through 31 Ashadh, post depreciation runs, post TDS provisions, generate trial balance, lock the period. Each step has a checkpoint that prevents progression until the previous step is verified complete. The locked period then provides the comparative baseline for the next fiscal year's reports.
A common audit finding in Nepali businesses is back-dated entries posted into a closed period after the audit has already begun. This happens when the accounting software allows entries to any date by default, with no period-lock enforcement. The fix is not better discipline - it is software that enforces the lock at the system level so that even the head of finance cannot post into Shrawan of last fiscal year without an explicit, logged reopen action.
Comparative Reporting Across Nepali Fiscal Years
Year-over-year comparison is one of the most useful reports a finance team produces, and one of the most frequently broken in non-native Nepal software. Comparing 2080-81 against 2079-80 should be a single report selection - not a custom date range and a manual re-run for each prior year. Multi-year trend analysis on revenue by branch, gross margin by product, or operating expenses by category becomes routine when the system understands fiscal year as a first-class concept. The CA preparing year-end statements stops rebuilding comparisons in Excel and starts running them directly from the ERP.
Audit Pack Generation at Year-End
The last step of fiscal year management is producing the audit-ready package for the external auditor. This is more than just a printout of the Balance Sheet. The full audit pack typically includes the trial balance with comparatives, P&L with departmental breakdown, fixed asset schedules with depreciation movements, debtors and creditors ageing reports, VAT and TDS registers in IRD format, bank reconciliation statements, and the supporting voucher index. In a properly designed Nepal ERP, this is a single report group that runs at year-end and delivers the complete pack. In a weakly designed system, the same pack takes the accounting team three to five days to assemble manually.
Proper Nepal fiscal year management is not about a calendar display option. It is about dual-calendar at the transaction level, native trimester recognition, enforced period locking, year-over-year comparison as a first-class report, and an audit pack that generates in one run rather than being assembled by hand.
Before the auditor opens your books for the year, confirm that period locks are enforced through 31 Ashadh, that all dates show both BS and AD where required, and that trimester reports run correctly against IRD's four-month periods. Errors discovered during audit are far more expensive to fix than the same errors caught during routine close.
Frequently Asked Questions
Many can be configured to use Shrawan-to-Ashadh as a custom fiscal year, but few support it as a native structure. The visible reports may show the correct year boundary, but internal features like trimester period recognition, BS-AD dual calendar at the transaction level, and IRD-format VAT registers are typically missing. The result is that the software produces correct outputs for management reports and incorrect or incomplete outputs for statutory filings. Nepal-built ERP avoids this gap by treating BS and the Shrawan-to-Ashadh year as primary rather than secondary concepts.
The conversion is exact rather than approximate - 1 Shrawan 2081 BS corresponds to a specific Gregorian date that the system stores precisely. The edge cases that matter are transactions dated at the end of Ashadh or the start of Shrawan, where a one-day error could place an entry in the wrong fiscal year entirely. A well-designed Nepal ERP handles this by storing both dates at entry time so the fiscal year placement is unambiguous and verifiable from the source document. The system never tries to guess - it stores what was entered and what it converts to.
The practical risks fall into three categories. First, statutory filings to IRD may be wrong because trimesters are misaligned or VAT register formats do not match the required layout. Second, comparative reports may be unreliable because the system is calculating year-over-year across calendar boundaries rather than fiscal ones. Third, the audit becomes slower and more expensive because the auditor has to verify date placements manually rather than trust the system. None of these is dramatic in a single month, but compounded across years they add real cost and real compliance exposure.
Nepal's Fiscal Calendar Built Into the Core, Not Bolted On
MISAC stores both Bikram Sambat and Gregorian dates on every transaction natively. An accountant entering a vendor bill dated 12 Shrawan 2081 sees the AD date alongside without converting in her head; an entry from a bill dated in AD shows the BS equivalent the same way. The dual calendar runs through every module - sales, purchases, payroll, inventory, fixed assets - because it is implemented at the data layer rather than as a display setting. Reports, registers, and exports all carry the correct calendar where each is required.
The fiscal year structure follows the same principle. Shrawan-to-Ashadh is the default; four-month trimesters are recognised as the IRD VAT periods; period locks engage at year-end closing and require explicit authorisation to reopen. Comparative reports across multiple Nepali fiscal years run as a single selection - 2080-81 against 2079-80 against 2078-79 - rather than being rebuilt in Excel each time. The IRD-format VAT register and TDS per-heading register in both Nepali and English match the layout the IRD officer expects to receive.
MISAC Intelligence Pvt. Ltd. has spent over a decade building accounting and ERP for Nepali businesses across trading, construction, hospitality, cooperative, and service sectors. The Nepal calendar and fiscal year handling has been refined through hundreds of year-end closings at customer sites - not designed in a conference room and shipped untested. If you want to see what truly native fiscal year management looks like in practice, the MISAC team can walk you through a live system.
