Every year, as Dashain approaches, employers across Nepal face the same recurring task: calculating and disbursing festival bonuses correctly under the Bonus Act. What looks like a simple percentage calculation on paper often trips up payroll teams when it comes to tax treatment, deadlines, and documentation. Getting it wrong doesn't just create employee dissatisfaction, it can expose the business to penalties during a labor or tax inspection.
This guide walks employers through what the law requires, how bonus TDS is actually calculated, and where most companies go wrong.
Statutory Bonus Act Requirements
Nepal's Bonus Act requires enterprises that generate profit during a fiscal year to distribute a defined percentage of that profit as bonus to eligible employees, subject to minimum and maximum limits set out in the Act. Key points employers need to keep in mind include:
- Eligibility: Employees who have worked a minimum qualifying period during the fiscal year are generally entitled to a bonus, calculated proportionally where applicable.
- Bonus pool calculation: The total bonus amount is derived from the enterprise's net profit for the fiscal year, following the specific formula and ceilings prescribed under the Act, rather than being an arbitrary management decision.
- Bonus fund allocation categories: A portion of the bonus amount is typically allocated toward a welfare fund and other statutory categories, in addition to direct employee distribution, as prescribed by the Act.
- Loss-making enterprises: Companies that did not generate distributable profit during the year may not have a statutory bonus obligation for that period, though any festival allowance paid voluntarily is treated differently for tax purposes than a statutory bonus.
How TDS on Bonus Is Calculated
A common misconception among payroll teams is that bonus tax simply gets blended into the employee's regular monthly salary TDS calculation. In practice, tax authorities expect bonus and festival payments to be assessed properly against the employee's total annual taxable income, applying the correct marginal tax rate for that portion of income, rather than being under-withheld as if it were a flat, low-rate payment.
Employers should treat the bonus as additional income added to the employee's projected annual salary income, then compute the incremental tax liability that this addition creates, and withhold that amount at the time of bonus disbursement. Failing to do this correctly typically results in under-withholding, which shifts an unexpected tax burden onto the employee at year-end reconciliation, or onto the employer if IRD identifies the shortfall.
Common Employer Mistakes
- Treating bonus as tax-free: Some employers mistakenly assume festival bonuses are exempt from tax entirely, which is incorrect; bonus income is taxable and must be withheld appropriately.
- Flat-rate under-withholding: Applying a low flat percentage TDS on the bonus amount without considering the employee's actual marginal tax bracket for the year.
- Missing the welfare fund allocation: Failing to properly allocate the statutory portion of the bonus pool toward the welfare fund as required under the Act.
- Late disbursement: Paying the bonus after the statutory deadline, which can trigger separate compliance issues under the Bonus Act independent of the tax treatment.
- Inconsistent documentation: Not maintaining clear records showing how the bonus pool was calculated from net profit, which becomes a problem if the calculation is questioned during an audit or labor inspection.
Deadline for Bonus Disbursement
The Bonus Act prescribes a specific window within which the calculated bonus must be distributed to eligible employees following the close of the fiscal year in which the profit was earned. Employers should build this deadline into their annual payroll and finance closing calendar well in advance, since late disbursement is treated as non-compliance regardless of whether the underlying profit calculation was accurate. Coordinating the bonus calculation with the year-end audit and financial statement finalization process is the most reliable way to avoid missing this deadline.
Frequently Asked Question
Is bonus tax calculated separately from monthly salary tax?
The bonus itself is disbursed as a separate payment event from the regular monthly salary, but for tax purposes it is not treated in isolation from the employee's overall annual income. The correct approach is to add the bonus amount to the employee's projected total annual taxable income and apply the appropriate marginal tax rate to determine the incremental TDS due on that bonus amount, rather than taxing it at a flat rate disconnected from the employee's actual income bracket.
