1. What is Nepal's income tax and who must pay it?

Nepal levies income tax on every individual whose annual assessable income exceeds the applicable threshold under the Income Tax Act 2058 (ITA 2058) — the primary legislation governing individual and corporate taxation in Nepal. The ITA 2058 is administered by the Inland Revenue Department (IRD), a department under the Ministry of Finance. Each year, the Finance Act updates tax rates, thresholds, and deductions. The Finance Act 2082, passed by Nepal's Parliament in Ashadh 2082, confirmed that all individual income tax parameters remain unchanged from FY 2081/82.

This continuity matters for anyone searching for "nepal income tax slab 2081/82" — the slabs are identical in 2082/83. The Finance Minister explicitly stated in the Ashadh 15, 2082 budget speech that no changes to individual income tax rates were introduced for the new fiscal year.

Who must pay income tax in Nepal?

• Salaried employees: Tax is deducted monthly at source (TDS) by the employer. No separate annual filing is required if employment is the only income source and the employer deducts correctly.
• Self-employed professionals: Doctors, lawyers, architects, consultants, and freelancers must pay advance tax quarterly and file an annual income tax return with IRD by end of Poush (approximately mid-January).
• Business owners: Individual proprietors report business income as personal income for progressive tax. Partnership income is taxed at the individual partner level.
• Rental income earners: Property rental income is included in total assessable income for progressive tax purposes.
• Investment income earners: Interest income, capital gains, and dividends may attract withholding tax or be included in total income depending on the source.

Who is below the taxable threshold?

Individuals earning below Rs 5,00,000 per year (single filer) or Rs 6,00,000 per year (married filer) are below the income tax threshold and owe no income tax for FY 2082/83. Note: the 1% Social Security Tax (SST) still technically applies at the lowest income level — but is waived for SSF contributors and does not apply to below-threshold earners who have no taxable income at all.

2. Income tax slabs FY 2082/83: Single and Unmarried Filers

Nepal applies six progressive income bands to individual income. The critical rule: each band is taxed at its own rate independently. You never pay your highest applicable rate on your full income. If you earn Rs 15,00,000 per year, you do not pay 30% on Rs 15 lakhs — you pay 30% only on the income above Rs 10,00,000, with lower rates applying to the income in lower bands.

Band 1 is classified as a Social Security Tax (SST) under the Finance Act — legally distinct from income tax. It carries a unique waiver mechanism through SSF enrollment that no other band has.

Source: Finance Act 2082, First Schedule, Part 1. Rates confirmed unchanged from Finance Act 2081.

3. Income tax slabs FY 2082/83 — married couple filers

Married couple filers in Nepal receive two advantages over single filers: a higher Band 1 threshold (Rs 6,00,000 vs Rs 5,00,000) and correspondingly higher thresholds for Bands 2 and 3. The Band 1 advantage saves Rs 1,000 per year in SST — or is waived entirely for SSF contributors. The married option is almost always more tax-efficient than single status for legally married taxpayers.

A married person may legally opt for single filer status if it results in lower tax. In practice, the married option saves more tax in nearly all scenarios because the higher Band 1 and Band 2 thresholds absorb more income at lower rates. Only in very specific tax structuring situations — which require professional advice — might single status be preferable for a married taxpayer.

4. The 1% SST — is it income tax or social security tax?

This is the single most misunderstood element of Nepal's payslip for most salaried employees. The 1% levy on Band 1 income is formally classified as a Social Security Tax (SST) under Finance Act 2082, First Schedule, Part 1 — it is legally distinct from income tax under ITA 2058. Here is why this distinction matters in practice:

• Waiver mechanism: The SST has its own unique waiver (SSF enrollment) that applies to no other band. You cannot waive income tax on Bands 2–6 through any contribution — only Band 1 SST has this property.
• Revenue allocation: SST revenue is directed to social security program funding, not to Nepal's general consolidated fund like income tax revenue.
• EPF does NOT waive SST: Employees contributing to EPF (Employee Provident Fund / Karmachari Sanchaya Kosh) still owe the Band 1 SST. Only SSF enrollment triggers the waiver.
• Voluntary SSF also qualifies: Self-employed individuals who voluntarily enroll in SSF can also waive their Band 1 SST — not just formal sector salaried employees.

5. The SSF waiver — how SSF enrollment eliminates Band 1 tax

The Social Security Fund (SSF), established under the Social Security Act 2074 and managed by the SSF Management Board at ssf.gov.np, is Nepal's contributory national social insurance program. For every enrolled employee, the Band 1 SST is completely waived — but the SSF offers far more than this tax benefit.

SSF contribution structure FY 2082/83

Note: Employer's 20% contribution is an additional cost to the company and does not reduce employee take-home pay. It is included in CTC calculations.

Social security benefits provided by SSF enrollment

• Medical benefit: Up to Rs 1,00,000 per hospitalization incident at SSF-empaneled hospitals across Nepal
• Accident benefit: Compensation of 60%–100% of base salary for workplace accidents resulting in partial or full disability
• Maternity benefit: 60 days paid leave at full salary for female employees, plus Rs 50,000 medical cost reimbursement per delivery
• Dependent family benefit: Minimum Rs 7,00,000 lump-sum payment to dependents if the contributor dies while in service
• Old-age pension: Monthly pension after minimum 15 years of SSF contribution — computed as a percentage of average base salary over contribution years
• Tax benefit: Complete waiver of Band 1 SST — saving Rs 5,000–6,000 per year annually

6. All Deductions That Reduce Your Taxable Income: Complete List

Before applying progressive slab rates, Nepal's tax law allows specified deductions from gross income to arrive at assessable income — the figure on which bands are applied. Every rupee of qualifying deduction reduces your assessable income, potentially dropping income from a higher band into a lower one. This is where proactive tax planning (within legal limits) can meaningfully reduce your annual liability.

How the combined deduction cap works in practice: An employee earning Rs 1,20,000/month gross (Rs 14,40,000/year) with annual SSF contribution of Rs 95,040: The cap is the lower of Rs 5,00,000 or Rs 14,40,000 ÷ 3 = Rs 4,80,000. Since Rs 95,040 is below Rs 4,80,000, the full SSF contribution is deductible. Add life insurance Rs 40,000 + health insurance Rs 20,000 = total deductions Rs 1,55,040. Assessable income = Rs 14,40,000 − Rs 1,55,040 = Rs 12,84,960.

7. Female 10% Tax Rebate (FRTC): Calculation and Qualifying Conditions

The Female Rebate on Tax Computation (FRTC), maintained under Finance Act 2082, provides female employees a 10% reduction on their total computed income tax. This was introduced by Nepal's Parliament as a gender-equity fiscal measure. Understanding what "10% rebate on tax" means (as opposed to 10% off assessable income) is critical to computing it correctly.

Three conditions — all must be met

1. The taxpayer must be female
2. The income must be employment income only — salary and wages from a registered employer with TDS deducted
3. No other income source — rental income, business income, freelance income, capital gains, or investment income in addition to salary disqualifies the full rebate

Step-by-step FRTC calculation

8. How TDS is computed and deposited — employer obligations

Tax Deducted at Source (TDS) is the mechanism through which Nepal's IRD collects income tax from salaried employees each month. Your employer legally acts as a tax collection agent. The TDS process has strict deadlines — non-compliance attracts significant interest penalties.

When you change employers mid-year: Your new employer must compute TDS based on your full-year projected income — including what your previous employer already paid you. Submit your previous employer's Form 2 or income statement to your new HR department. Failure to do this results in under-deduction from the new employer and a potentially large tax liability at year end that you must settle personally with IRD.

10. Worked Example 2: Rs 1,20,000 Monthly Gross, Married Filer, SSF Enrolled

11. IRD filing deadlines and penalties: FY 2082/83

E-filing is available 24/7 at ird.gov.np. Taxpayers need a PAN (Permanent Account Number) to file. PAN registration can be done online for new taxpayers. IRD also operates helpdesk services at all major district offices and the Lazimpat head office in Kathmandu.
