Nepal Income Tax FY 2083/84: Complete Guide to New Unified Tax Slabs

If you earn a salary in Nepal, run a small business, or receive pension alongside other income, the FY 2083/84 (2026/27) income tax rules directly affect how much tax you pay and how much stays in your pocket. The Finance Act 2083 — introduced through the budget for fiscal year 2083/84 — is one of the most significant personal income tax reforms in recent years.

This guide walks you through everything a resident natural person needs to know about the upcoming unified tax slabs: what changed from last year, how each band works, what you can deduct, what credits reduce your final bill, and how to estimate tax at different salary levels. Use it alongside our free Nepal Income Tax Calculator, which applies these rules automatically.

Quick summary: what's new in FY 2083/84?

Effective date: Shrawan 1, 2083 BS (16 July 2026), for income earned during income year 2083/84.

Who does this guide apply to?

The unified slabs apply to resident natural persons — individual human taxpayers who are tax residents of Nepal. This includes:

• Salaried employees in the private sector, NGOs, and government
• Sole proprietors and freelancers with business income
• Pensioners with taxable pension receipts
• Individuals with mixed income (salary + rent, investments, etc.)

The rules described here focus on the most common scenario — employment income — but the same slab table applies once you arrive at taxable income, regardless of income source.

Understanding progressive tax (how slabs actually work)

Nepal uses a progressive income tax system. This means:

• Each tax rate applies only to the income within that specific band.
• Moving into a higher slab does not increase the tax rate on income you already earned in lower bands.
• Your marginal rate (the rate on your next rupee of income) can be higher than your effective rate (total tax ÷ total income).

Example: why progressive tax matters

Suppose your taxable income is Rs 12,00,000. Here is how the FY 2083/84 slabs apply:

Your effective rate is 2.5% (30,000 ÷ 12,00,000), even though part of your income was taxed at 10%. You did not pay 10% on the full Rs 12 lakh.

The unified tax slabs for FY 2083/84 (full table)

Finance Act 2083 removed separate assessment for single and married taxpayers. Every resident natural person now uses the same five-band schedule:

* Band 1 is designated as Social Security Tax (deposited to revenue account 11211). Exemptions apply — see below.

** Band 5 = 27% base rate + 2% surcharge on income above Rs 40 lakh.

Band-by-band guide

Band 1 (1% — up to Rs 10 lakh): This is the band most salaried workers will interact with. Despite common belief, it is not tax-free. A person with exactly Rs 10,00,000 in taxable income pays Rs 10,000 per year (~Rs 833/month). The rate is low, but it applies to the entire first Rs 10 lakh, not just the portion above a threshold.

Band 2 (10% — Rs 10L to 15L): The next Rs 5 lakh of income is taxed at 10%. Maximum additional tax in this band: Rs 50,000. Combined with Band 1, someone at exactly Rs 15 lakh taxable income pays Rs 60,000 total.

Band 3 (20% — Rs 15L to 25L): Covers the next Rs 10 lakh. This is where tax starts to feel significant for upper-middle earners. Maximum tax in this band alone: Rs 2,00,000.

Band 4 (27% — Rs 25L to 40L): The next Rs 15 lakh is taxed at 27%. Maximum in this band: Rs 4,05,000. Employees in senior roles or dual-income households without heavy deductions often land here.

Band 5 (29% — above Rs 40L): Income exceeding Rs 40 lakh is taxed at 29%. The 29% includes a 2% surcharge on that portion. High earners benefit from the old 39% top rate being gone, but tax remains substantial.

Maximum tax at key income levels (no deductions, no credits)

These figures assume taxable income equals gross income — no reductions, deductions, or credits:

Use the income tax calculator for your exact situation — deductions and credits change these numbers significantly.

What changed from FY 2082/83? (old slabs for comparison)

Understanding the old system helps you see why take-home pay may look different from July 2026 onward.

Old slabs (FY 2082/83 — single assessment)

Married couples had slightly higher thresholds on the first bands (e.g. Rs 6 lakh for the 1% band). That distinction no longer exists.

Who wins under the new rules?

• Rs 5L – 10L earners: Much lower tax. The entire range now sits in the 1% band instead of climbing into 10% and 20% bands sooner.
• Rs 10L – 25L earners: Generally lower tax due to wider low-rate bands and a lower top rate.
• Above Rs 40L: Top rate dropped from 39% to 29% — meaningful savings at the margin.
• Very specific edge cases: A small number of taxpayers near old married-couple thresholds should run both scenarios in the calculator.

Social Security Tax: the 1% first-band rule explained

The 1% rate on the first Rs 10,00,000 is not ordinary income tax in the traditional sense. It is classified as Social Security Tax under the Finance Act 2083, earmarked for revenue account 11211.

Who is exempt from the 1% Social Security Tax?

You do not pay the 1% on the first band if any of the following apply:

1. You are a sole proprietor
2. You have pension income included in your taxable income
3. You receive income from a contribution-based pension fund
4. You already contribute to the Social Security Fund (SSF)

For salaried employees enrolled in SSF, this exemption can eliminate Rs 10,000 in annual tax on the first Rs 10 lakh of taxable income — a direct saving of roughly Rs 833 per month.

Practical tip

If your employer deducts SSF from your salary, make sure you tick SSF in the tax calculator. You may qualify for both the SS tax waiver and a retirement-fund reduction on taxable income.

How to calculate taxable income (step by step)

Tax is not calculated on your gross salary alone. The law allows reductions and deductions that lower the amount subject to slabs. Credits then reduce the tax itself.

The calculation flow

Gross / assessable income
  − Reductions in income
  = Income after reductions
  − Deductions on income
  = TAXABLE INCOME  →  apply slab rates
  = Gross tax
  − SS tax waiver (if eligible)
  − Tax credits (female, medical, foreign)
  = TAX PAYABLE

Take-home pay = Gross income − Tax payable − Payroll deductions (SSF, PF, CIT, etc.)

Critical distinction: Reductions and deductions lower taxable income. Credits lower tax payable. Payroll items like CIT come out of your salary and may reduce taxable income — they affect both tax and take-home.

Reductions in income (lower your taxable base)

These are subtracted from assessable income before slabs are applied.

Life insurance premium

• Rule: Lower of actual annual premium paid or Rs 40,000
• Who benefits: Anyone with a life insurance policy from a resident insurer
• Example: You pay Rs 35,000/year in premiums → Rs 35,000 reduction. You pay Rs 55,000 → only Rs 40,000 counts.

Medical (health) insurance premium

• Rule: Lower of actual premium or Rs 20,000
• Requirement: Policy must be with a resident insurer/insurance company
• Tip: Keep premium receipts; the deduction uses what you actually paid, not the sum insured.

Private building insurance

• Rule: Lower of actual annual premium or Rs 10,000
• Applies to: Residential buildings you own, insured with a resident insurer

Approved retirement fund contributions

• Rule: Lower of ⅓ of income, Rs 5,00,000, or actual contribution
• Covers: SSF, Provident Fund (PF), Citizen Investment Trust (CIT), and other approved funds
• Example: Annual income Rs 12,00,000, you contribute Rs 2,00,000 to CIT. Cap = min(4,00,000 / 5,00,000 / 2,00,000) = Rs 2,00,000 deductible.

Children's education fees

• Rule: 25% of annual tuition paid, or Rs 25,000, whichever is lower
• Example: Tuition Rs 80,000/year → 25% = Rs 20,000 deductible. Tuition Rs 1,50,000 → 25% = Rs 37,500, capped at Rs 25,000.

Deductions on income (additional relief)

These are separate from reductions and apply after reductions are taken.

Remote area allowance

Employees working in designated remote or less-developed areas get a flat additional deduction:

If you work outside major urban centres or in districts classified as remote, confirm your grade with your employer or IRD guidance.

Pension income relief

• Rule: Additional deduction of 25% of the first tax band (Rs 2,50,000) or actual pension receipts, whichever is lower
• Also triggers: Exemption from 1% Social Security Tax on the first band
• Example: Pension income Rs 3,60,000/year → deduction = min(2,50,000 / 3,60,000) = Rs 2,50,000

Incapacitated natural person

• Rule: Additional deduction of 50% of the first tax band (Rs 5,00,000) or actual income, whichever is lower
• Purpose: Extra relief for qualifying incapacitated taxpayers

Foreign allowances (diplomatic missions)

If you are employed at a foreign diplomatic mission of Nepal, only 25% of foreign allowances count as employment income. The remaining 75% is excluded from assessable income.

Example: Foreign allowance Rs 4,00,000/year → only Rs 1,00,000 is taxable; Rs 3,00,000 is excluded.

Payroll deductions: what comes out of your salary

These items reduce your take-home pay. Many also reduce taxable income:

CIT is monthly. If you contribute Rs 14,000 per month, that is Rs 1,68,000 per year — both a tax reduction and Rs 14,000 less in your monthly bank deposit.

Rebates on tax liability (tax credits)

Credits reduce the tax after slabs are calculated. They do not change taxable income.

Female tax credit (10%)

• Who: Female natural persons with only remuneration income (salary/wages — no business or rental income mixed in)
• Amount: 10% of tax liability
• Example: Tax before credit = Rs 50,000 → credit = Rs 5,000 → tax payable = Rs 45,000

Medical tax credit

• Amount: 15% of approved medical expenses (plus prior-year carry-forward), up to Rs 1,500 a year — whichever is lower
• Cap: Cannot exceed your actual tax liability
• Example: Medical expenses Rs 40,000 → 15% = Rs 6,000 → credit = Rs 6,000 (if tax liability allows)

Foreign tax credit

• Who: Residents who paid tax abroad on income also declared in Nepal
• Per country: Lower of (foreign income × average Nepal tax rate) or (actual foreign tax paid)
• Purpose: Prevents double taxation on the same income

Tax exemptions worth knowing

Compensation for deceased persons

Any compensation received against a deceased natural person is not required to be included in income.

NBCA-only gains (optional non-filing)

A natural person with only gains from disposal of Non-Business Chargeable Assets (NBCA) may opt not to file under Section 96, subject to conditions.

Vehicle hire income

A natural person (other than a sole proprietor) with income solely from vehicle on hire may not be required to file — confirm with current IRD circulars.

Income tax return filing: when you must file

Missing the filing deadline when required can attract penalties. Mark your calendar if you are near the Rs 40 lakh taxable income threshold.

Worked examples at different salary levels

All examples use FY 2083/84 unified slabs. Figures are illustrative — use the calculator for precision.

Example 1: Entry-level salary — Rs 35,000/month

• Annual gross: Rs 4,20,000 (12 months)
• Deductions: None
• Taxable income: Rs 4,20,000
• Slab tax: 1% × 4,20,000 = Rs 4,200/year (~Rs 350/month)
• Take-home: ~Rs 34,650/month before other payroll items

Example 2: Mid-level salary with CIT — Rs 56,000/month

• Annual gross: Rs 6,72,000
• CIT: Rs 14,000/month = Rs 1,68,000/year
• Taxable income: ~Rs 5,04,000 (after CIT reduction)
• Slab tax: 1% × 5,04,000 = Rs 5,040/year
• Take-home: Rs 56,000 − Rs 14,000 (CIT) − Rs 420 (tax) ≈ Rs 41,580/month

Example 3: Senior salary with SSF and insurance — Rs 1,20,000/month

• Annual gross: Rs 14,40,000 (basic at 60% = Rs 8,64,000)
• Employer's SSF 20%: Rs 1,72,800 is added to income → assessable income Rs 16,12,800
• SSF reduction (31% of basic): Rs 2,67,840; also exempts the 1% SS tax
• Life insurance Rs 30,000: Full amount deductible
• Taxable income: Rs 13,14,960
• Tax: Rs 41,496 on the slabs − Rs 10,000 SS tax waiver = Rs 31,496/year (about Rs 2,625/month)
• Female + salary-only: 10% credit brings it to about Rs 28,346

Example 4: High earner — Rs 3,50,000/month

• Annual gross: Rs 42,00,000
• After typical SSF/PF/CIT: Taxable income may land in Band 4 or 5
• Slab tax: Substantial — often Rs 8–10 lakh+ before credits
• Must file return: Taxable income almost certainly exceeds Rs 40 lakh threshold
• Planning: Maximise retirement, insurance, and remote-area deductions if eligible

Planning checklist for FY 2083/84

Use this checklist before Shrawan 1, 2083 BS (16 July 2026):

1. Confirm your employer's payroll setup — SSF, PF, CIT, and monthly TDS withholding
2. Enter CIT as a monthly amount when estimating take-home (not annual)
3. Collect insurance premium receipts for life, medical, and building policies
4. Check remote area grade if you work outside Kathmandu or in designated districts
5. Female employees: Confirm whether you have only remuneration income for the 10% credit
6. Track medical expenses for the medical tax credit (keep bills for 15% calculation)
7. Run the calculator at least twice a year — after mid-year raise and before year-end
8. File on time if taxable income exceeds Rs 40 lakh

Frequently asked questions

Is income up to Rs 10 lakh completely tax-free?

No. The first Rs 10 lakh is taxed at 1%. At exactly Rs 10 lakh taxable income, you pay Rs 10,000 per year. The band is low-tax, not zero-tax.

Do married couples still get a higher threshold?

No. Finance Act 2083 unified slabs. Married and single taxpayers use the same Rs 10 lakh first band and identical rates.

Does my employer's SSF payment exempt me from the 1% tax?

Yes, if you are an SSF contributor. The 1% Social Security Tax on the first band is waived for SSF participants, sole proprietors, and qualifying pension recipients.

Is CIT a tax deduction or a salary deduction?

Both. CIT reduces your taxable income (within the retirement cap) and is deducted from your monthly salary. It lowers your tax bill and your take-home at the same time.

What is the difference between a reduction and a deduction?

Reductions (insurance, retirement, tuition) lower assessable income before slabs. Deductions (remote area, pension relief, incapacitated relief) are additional subtractions after reductions. Credits (female, medical, foreign) lower the tax itself after slabs.

When do the new slabs take effect?

Shrawan 1, 2083 BS (16 July 2026) for income year 2083/84. Salary earned from that date forward is taxed under the new rules.
