Salary Tax Calculator Nepal 2082/83 — Worked Examples

Most salaried employees in Nepal compute their tax by mentally applying the top-slab percentage to gross salary — and end up either over-paying through aggressive payroll TDS, or under-paying and facing year-end reconciliation interest. The progressive slab system means the actual tax on any given salary level is meaningfully lower than the top-slab rate would suggest, and the deductions allowed under the Income Tax Act 2058 — Social Security Fund contributions, Employee Provident Fund, Citizen Investment Trust, life insurance, health insurance — can reduce the effective rate further. Knowing how to run the calculation correctly is the difference between an accurate monthly take-home and a year-end surprise.

This guide is the 2026 (FY 2082/83) practitioner's worked-example walkthrough on salary tax calculation in Nepal — the six-band progressive slab structure for single and married filers, the SSF-contributor waiver on the first 1% band, the deduction stack (SSF + EPF + CIT capped at the lower of NPR 500,000 or one-third of taxable income; life insurance up to NPR 40,000; health insurance up to NPR 20,000), step-by-step worked examples at common salary levels, the female-taxpayer 10% rebate, and the interaction with payroll TDS.

What is the salary tax slab structure in Nepal for FY 2082/83?

Nepal applies a six-band progressive income tax structure to salaried individuals under the Income Tax Act 2058 and the Finance Act 2082. The rates rise from 1% (Social Security Tax) on the first slab to 39% on the top slab, applied incrementally — each higher rate hits only the portion of income above the prior threshold, never the entire income. The single-filer and married-couple-joint-filer schedules share the same rate structure (1% / 10% / 20% / 30% / 36% / 39%) but the slab thresholds differ: the married couple's first three slabs are NPR 100,000 wider at the bottom, giving a small saving at lower income levels. The 36% and 39% top bands trigger at the same thresholds (NPR 2,000,000 and NPR 5,000,000) for both filing categories.

For a single filer, the slabs are: 1% up to NPR 5,00,000; 10% on NPR 5,00,001-to-7,00,000; 20% on NPR 7,00,001-to-10,00,000; 30% on NPR 10,00,001-to-20,00,000; 36% on NPR 20,00,001-to-50,00,000; and 39% above NPR 50,00,000. For a married couple filing jointly, the slabs are: 1% up to NPR 6,00,000; 10% on NPR 6,00,001-to-8,00,000; 20% on NPR 8,00,001-to-11,00,000; 30% on NPR 11,00,001-to-20,00,000; 36% on NPR 20,00,001-to-50,00,000; and 39% above NPR 50,00,000. The rates and thresholds for FY 2082/83 are unchanged from the structure introduced in FY 2081/82.

What is the SSF-contributor waiver on the 1% Social Security Tax?

The first slab carries a 1% Social Security Tax (SST) — a separate levy from the income tax proper, intended to fund a contributory social-security framework. The defining rule is the SSF-contributor waiver: where the employee (and, for joint couple filing, both spouses) contributes to the Social Security Fund established under the Social Security Fund Act 2074 (2017), the 1% SST is not levied. SSF membership and contribution at the prescribed rates satisfies the social-security obligation directly, and a separate SST would amount to double-counting.

Practically, this means that an SSF-contributing salaried employee pays zero tax on the first NPR 500,000 of annual income (single) or NPR 600,000 (married couple). Combined with the deductions allowable for the SSF contribution itself plus EPF and CIT contributions, the effective tax-free threshold for an SSF-contributing employee can rise substantially. The waiver is claimed on the annual return with a copy of the SSF contribution remittance receipt as supporting evidence; employers handling payroll TDS for SSF-contributing employees apply the waiver in their monthly withholding calculation directly.

What deductions can be claimed against salary income?

Section 21 of the Income Tax Act 2058 read with the Finance Act 2082 allows several categories of deductions against salaried individual income:

• Social Security Fund (SSF) contribution — employer 20% and employee 11% of basic salary in the standard SSF scheme. The employee's share is deductible against taxable income.
• Employee Provident Fund (EPF) contribution — typical 10%-each employer-employee scheme under the Employees Provident Fund Act 2019 (2)BS) for employees not in the SSF.
• Citizen Investment Trust (CIT) contribution — voluntary retirement-savings contribution to the CIT scheme.
• Life insurance premium — paid on a life insurance policy on the taxpayer's own life, deductible up to a maximum of NPR 40,000 per year.
• Health insurance premium — paid on a health insurance policy covering the taxpayer or dependants, deductible up to a maximum of NPR 20,000 per year.

The SSF + EPF + CIT combined deduction is capped at the lower of NPR 500,000 or one-third of taxable income. So a salaried employee earning NPR 1,200,000 has a combined SSF/EPF/CIT cap of NPR 400,000 (one-third); an employee earning NPR 2,400,000 has a cap of NPR 500,000 (the absolute ceiling kicks in). The life-insurance and health-insurance caps are separate and additional. For an employee in the SSF scheme with the maximum permissible contribution plus full life and health insurance, the total deduction can approach NPR 560,000 per year, dropping the assessable income materially below the gross.

How do I calculate my salary tax step by step?

The calculation is a four-step process, identical for every salaried employee:

Step 1 — Compute total annual income. Multiply monthly basic salary by the number of months in the income year (typically 12 for a full year, or fewer for a partial year if joining or leaving employment), then add any annual bonus (Dashain festival bonus is conventional and equal to one month's salary), any allowances that are taxable (vehicle, housing, education in certain categories), and any other employment-related cash or kind benefits. The result is gross annual income.

Step 2 — Subtract eligible deductions. Identify the employee's SSF contribution (or EPF where the employee is in the EPF rather than SSF scheme), any voluntary CIT contribution, any life-insurance premium paid (capped at NPR 40,000), and any health-insurance premium paid (capped at NPR 20,000). Apply the combined SSF/EPF/CIT cap of NPR 500,000 or one-third of taxable income, whichever is lower. Subtract the total from gross annual income to reach net assessable income.

Step 3 — Apply the six-band slab rate. Compute the tax band by band: the rate applicable to each slab is multiplied by the income in that slab (not by total income). For SSF contributors, the 1% on the first slab is waived, so the calculation starts at the 10% band. Sum the band-wise tax amounts to get the gross income tax.

Step 4 — Apply rebates and credits. If the taxpayer is a woman filing individually, apply the 10% female-taxpayer rebate to the gross income tax. Subtract any TDS already paid (the payroll withholding the employer remitted during the year). Pay or claim refund as the case may be. The annual return filed by Ashoj end reconciles to a final net position.

Worked example 1 — Single filer earning NPR 50,000 monthly

Total annual income (no bonus): NPR 50,000 × 12 = NPR 6,00,000. Assume no deductions and the employee is not in the SSF scheme. The slab-by-slab tax computation is:

• First NPR 500,000 at 1% SST = NPR 5,000
• Next NPR 100,000 at 10% = NPR 10,000
• Total annual tax = NPR 15,000 (effective rate 2.5%)

Monthly payroll TDS = NPR 15,000 ÷ 12 = NPR 1,250. The take-home monthly salary becomes NPR 50,000 − 1,250 = NPR 48,750.

If the same employee contributes to the SSF, the 1% SST on the first slab is waived. The tax becomes only NPR 10,000 (the 10% band remains), and the SSF contribution itself is also deductible. With a typical employee SSF contribution of 11% of basic salary (NPR 66,000 per year), the assessable income drops to NPR 6,00,000 − 66,000 = NPR 5,34,000. The first NPR 5,00,000 is now in the SST-waived band, and only NPR 34,000 falls in the 10% band, giving tax of NPR 3,400. The combined effect is a tax of approximately NPR 3,400 instead of NPR 15,000 — a saving of NPR 11,600 per year just from SSF enrolment.

Worked example 2 — Single filer earning NPR 1,00,000 monthly with one-month bonus

Total annual income with Dashain bonus: (NPR 1,00,000 × 12) + 1,00,000 = NPR 13,00,000. Assume the employee is in the SSF scheme with 11% contribution (NPR 1,32,000 deductible), plus NPR 25,000 life insurance and NPR 15,000 health insurance.

• Total deductions: 1,32,000 + 25,000 + 15,000 = NPR 1,72,000 (within all caps)
• Net assessable income: 13,00,000 − 1,72,000 = NPR 11,28,000

Slab-by-slab tax (with SSF, so 1% band is waived):

• First NPR 500,000 at 0% (SSF waiver) = NPR 0
• Next NPR 200,000 at 10% = NPR 20,000
• Next NPR 300,000 at 20% = NPR 60,000
• Next NPR 128,000 at 30% = NPR 38,400
• Total annual tax = NPR 1,18,400 (effective rate 9.1% on gross income)

Without the SSF waiver and without deductions, the same gross income (NPR 13,00,000) would attract tax of approximately NPR 1,85,000 — a difference of about NPR 66,600 saved through SSF enrolment plus full deduction usage.

Worked example 3 — Married couple filing jointly, earning NPR 2,00,000 combined monthly

Combined annual income with bonuses: (NPR 2,00,000 × 12) + 2,00,000 = NPR 26,00,000. Assume one spouse is in SSF (NPR 80,000 deductible), and they take NPR 40,000 life insurance + NPR 20,000 health insurance (combined household).

• Total deductions: 80,000 + 40,000 + 20,000 = NPR 1,40,000
• Net assessable income: 26,00,000 − 1,40,000 = NPR 24,60,000

Slab-by-slab tax under the married-couple schedule (with SSF, 1% band waived):

• First NPR 600,000 at 0% (SSF waiver) = NPR 0
• Next NPR 200,000 at 10% = NPR 20,000
• Next NPR 300,000 at 20% = NPR 60,000
• Next NPR 900,000 at 30% = NPR 2,70,000
• Next NPR 460,000 at 36% = NPR 1,65,600
• Total annual tax = NPR 5,15,600 (effective rate 19.8%)

The couple's tax is less than the sum of two single-filer taxes on equivalent split incomes because the joint election uses the wider first slab. For couples where incomes are unequally distributed, single filing of each spouse can produce a different combined liability — modelling both options is the routine pre-filing discipline.

How does payroll TDS interact with the annual return?

Under Section 87 of the Income Tax Act 2058, the employer withholds tax at source on the monthly salary payment to the employee — the payroll TDS. The withholding is computed by estimating the employee's annual tax based on projected annual income, then dividing by 12 (or the remaining months in the year if the employee joined mid-year) to get the monthly withholding. The employer remits the withholding to IRD within the prescribed period and issues a TDS certificate to the employee. At year end, the employee files the annual return reconciling the year's total tax against the cumulative withholding — paying the shortfall or claiming the refund of any excess.

The accuracy of the year-end reconciliation depends entirely on the quality of the projection at the start of the year. Employers who estimate generously (e.g., assuming no deductions) over-withhold; the employee then claims the refund at year-end. Employers who under-estimate (e.g., assuming maximum deductions that don't materialise) under-withhold; the employee owes the shortfall plus possibly interest. The cleanest discipline is for the employee to advise the payroll team of their actual deduction plans at the start of the year (SSF enrolment status, insurance premiums, CIT contributions) so the TDS computation reflects the year's reality.

What is the female-taxpayer rebate?

Women filing individually as single filers receive a 10% rebate on their computed income tax liability. The rebate is a true tax reduction applied after the slab computation — a woman with computed tax of NPR 145,000 pays NPR 130,500 after the rebate (a saving of NPR 14,500). The rebate is not available in joint couple filing because the joint election treats the household as the tax unit; for a woman in a household where joint filing is optimal, the rebate would still be lost. Comparing single-vs-joint computation should include the rebate effect to get the apples-to-apples comparison.

The rebate is claimed automatically on the return for women filing under a female-PAN; no separate application is required. For payroll TDS purposes, an employer aware that the employee will file as a single woman can factor the 10% rebate into the monthly withholding computation, reducing the per-month TDS by the appropriate fraction. The most common payroll-team error is to ignore the rebate entirely, resulting in over-withholding and a year-end refund.

How do bonuses and allowances affect salary tax?

The most common variable income components for Nepal salaried employees are: Dashain bonus (the conventional one-month annual bonus paid in Dashain, equal to one month's basic salary), festival bonuses (smaller bonuses for other festivals where the employer's policy includes them), provident-fund employer match (the employer's matching contribution to the EPF or SSF — not directly taxable as employee income but factored into the SSF/EPF compliance), vehicle and housing allowances (taxable in full at the receipt level unless covered by specific Income Tax Rules exemptions), and medical reimbursements (generally non-taxable up to a prescribed cap, taxable above).

For the salary tax calculation, all taxable components are aggregated into the total annual income at Step 1. Non-taxable reimbursements and benefits in specific exempt categories are excluded. The employer's contribution to SSF or EPF is not included as employee income (it is the employer's expense), and is not deductible against employee tax (only the employee's own contribution is). For employees with multiple income sources — main employment plus side consulting or freelance — all sources must be aggregated for the annual return, with the year-end tax reconciling all withholdings against the total liability.

What are the most common salary tax computation mistakes?

From practitioner experience, the recurring errors are: applying the top-slab rate to the full income — leading to overestimated tax (the marginal rate applies only to the marginal income above the threshold, never to the total); missing the SSF waiver — many employees enrolled in SSF still pay 1% SST in the payroll TDS calculation because the payroll team did not capture the SSF status; missing the female-taxpayer rebate — particularly common where the employee's gender data was incorrectly captured at HR onboarding; misapplying the deduction caps — claiming SSF + EPF + CIT above the one-third-of-income cap, which gets disallowed at IRD review; forgetting Dashain bonus in the projection — the bonus pushes the annual income into a higher slab band, but the payroll computation often uses 12 × monthly without adding the bonus.

Less common but consequential: incorrect treatment of multiple-employer income — an employee changing jobs mid-year often ends up with the new employer applying TDS as if the new job is the only income, leading to under-withholding overall; spouse-as-couple election made without modelling — joint filing election is not automatically optimal, and many couples save tax by single-filing separately; missed life and health insurance deductions — premiums paid out-of-pocket but not captured in the payroll computation because the employee did not provide the documentation.
