If you're trying to figure out exactly how much income tax will come out of your salary for FY 2082/83, the six-band progressive slab system can look confusing at first glance. This guide breaks the calculation down step by step, with a full worked example, so you can check your own payslip or plan ahead with confidence.
The Six-Band Slab Table: Single vs. Married
For FY 2082/83, Nepal's individual income tax follows six progressive bands, with a higher first-band threshold for married couples filing jointly compared to single filers:
- Single filers: 1% up to NPR 5,00,000; 10% on the next NPR 2,00,000 (5–7 lakh); 20% on the next NPR 3,00,000 (7–10 lakh); 30% on the next NPR 10,00,000 (10–20 lakh); 36% on the next NPR 30,00,000 (20–50 lakh); 39% above NPR 50,00,000.
- Married couples (joint): 1% up to NPR 6,00,000; 10% on the next NPR 2,00,000 (6–8 lakh); 20% on the next NPR 3,00,000 (8–11 lakh); 30% on the next NPR 9,00,000 (11–20 lakh); 36% on the next NPR 30,00,000 (20–50 lakh); 39% above NPR 50,00,000.
The structure is progressive, meaning each rate only applies to the portion of income that falls within that specific band, not to your entire income. This is the single most common point of confusion: earning enough to reach the 30% band does not mean your entire salary is taxed at 30%, only the slice of income that falls within that band.
Step-by-Step Manual Calculation: NPR 100,000/Month Example
Let's walk through a single filer earning NPR 100,000 per month, for an annual salary of NPR 12,00,000, before any deductions, and not contributing to SSF.
- Band 1: 1% on the first NPR 5,00,000 = NPR 5,000
- Band 2: 10% on the next NPR 2,00,000 (5–7 lakh) = NPR 20,000
- Band 3: 20% on the next NPR 3,00,000 (7–10 lakh) = NPR 60,000
- Band 4: 30% on the remaining NPR 2,00,000 (10–12 lakh, within the 10–20 lakh band) = NPR 60,000
Total annual tax: NPR 5,000 + 20,000 + 60,000 + 60,000 = NPR 1,45,000, before any deductions or SSF waiver are applied. Divided across 12 months, this works out to roughly NPR 12,083 in monthly TDS, though actual monthly withholding may vary slightly depending on how your employer structures the annualized projection and any festival bonus included in a specific month.
The SSF Exemption on 1% SST Explained
The 1% rate on the first band is technically a Social Security Tax (SST), not ordinary income tax, and it is waived for employees who contribute to the Social Security Fund (SSF), since the SSF contribution itself is treated as fulfilling that social security obligation. In the example above, an SSF-contributing employee would save the NPR 5,000 charged on the first band, bringing total annual tax down to NPR 1,40,000. This waiver applies specifically to the first-band SST portion; it does not reduce tax owed in the higher bands.
Common Deductions: EPF, CIT, and Insurance
Before applying the slab rates, several deductions can reduce your taxable (assessable) income:
- Retirement contributions (SSF, EPF, CIT combined): Deductible up to the lower of NPR 5,00,000 or one-third of your taxable income, whichever is smaller.
- Life insurance premium: Deductible up to a cap of NPR 40,000 per year.
- Health insurance premium: Deductible up to a cap of NPR 20,000 per year.
These deductions are subtracted from your gross annual income before the slab rates are applied, so claiming everything you're entitled to can meaningfully reduce your final tax bill. Salaried employees whose employer handles routine TDS often forget to separately claim personal life or health insurance premiums that aren't captured automatically in payroll, so it's worth confirming these are properly accounted for, either through your employer or when reconciling your annual return.
Using a Calculator for Your Own Numbers
While the manual step-by-step method above works for any income level, the calculation gets more involved once you factor in multiple deductions, a festival bonus, and the SSF waiver together. For a quick sanity check, apply the band-by-band method shown above to your own gross annual income after deductions, working through each band in order until you reach your income level, then sum each band's tax contribution for your total liability.
Frequently Asked Question
How much tax on a 50 lakh salary in Nepal?
For a single filer earning exactly NPR 50,00,000 annually (before deductions, not contributing to SSF): 1% on the first 5 lakh (NPR 5,000), 10% on the next 2 lakh (NPR 20,000), 20% on the next 3 lakh (NPR 60,000), 30% on the next 10 lakh (NPR 3,00,000), and 36% on the next 30 lakh (NPR 10,80,000), bringing the total to NPR 14,65,000. Since the income falls exactly at the top of the 36% band, the 39% rate does not apply in this specific case. If this taxpayer contributes to SSF, the 1% SST is waived, bringing the total down to NPR 14,60,000. Applying eligible deductions (retirement contributions, life and health insurance premiums) before this calculation would reduce the taxable base and lower the final figure further.
