Payroll & SSF Contributions in Nepal

Published June 28, 2026 · Updated August 14, 2026 with a step-by-step monthly payroll cycle, a worked SSF/TDS example, and a FAQ section.

Payroll in Nepal isn't just calculating a salary and paying it — employers are responsible for TDS deduction, Social Security Fund contributions, and correct statutory record-keeping every single month, and small errors compound quickly across a full team. The short version for any employer setting this up: you need to register separately with the Social Security Fund before running SSF-based payroll, deduct income tax at source from every employee's salary based on the current fiscal year's slabs (not last year's), deposit both SSF contributions and withheld TDS monthly, and issue employees annual tax payment certificates for their own filing. Get any one of those wrong and the error doesn't stay contained to a single payslip — it compounds every month until someone catches it, usually at year-end reconciliation or when an employee's own return doesn't match what was actually withheld.

Social Security Fund contributions

Employers registered under the Social Security Fund contribute a percentage of employee salary, with a matching or complementary contribution from the employee's side, deposited monthly. SSF registration is a separate step from PAN and company registration, and needs to happen before an employer can legally run payroll under the SSF framework. This mirrors a pattern that shows up across Nepali business compliance generally — SSF registration doesn't happen automatically as a byproduct of OCR or PAN registration, and an employer who assumes it's bundled in with standard company setup can find themselves running payroll without the registration actually in place.

Beyond the contribution itself, SSF status has a direct effect on how much income tax an employee owes. If an employee contributes to SSF, the 1% social security portion of the first income tax slab is waived entirely — a benefit that, combined with the FY 2083/84 slab reset, can make a meaningful share of a salaried employee's income effectively tax-free. Getting an employee's SSF status correctly reflected in payroll isn't just an SSF compliance question — it directly changes their TDS calculation each month.

SSF enrollment itself became mandatory for a large share of employers in 2026, and the contribution ceiling has changed too — see our 2026 SSF compliance update for exactly who's now required to enroll and what the new ceiling means for higher earners. Minimum wage is worth checking against your base payroll figures as well — see our current minimum wage guide.

TDS on salary

Employers must deduct income tax at source from employee salaries each month, based on the applicable progressive tax slabs for the current fiscal year. Since tax slabs are periodically revised through the annual budget, payroll calculations need to be checked against the current year's rates, not carried over unchanged from the year before. FY 2083/84 is a clear recent example of why this matters: the tax-free threshold doubled to NPR 10 lakh and the top rate dropped from 39% to 29%, a change substantial enough that payroll calculated on the old table would meaningfully over-withhold from nearly every employee — see our full breakdown of the FY 2083/84 slab changes for the complete comparison. If you want to check a specific employee's withholding against the current slabs directly, our free Nepal Salary Tax Calculator handles SSF, EPF, CIT, and insurance deductions across all three recent fiscal years.

Under the Income Tax Act 2058, the employer acts as the withholding agent, deducting TDS before paying the employee and depositing it with the IRD — this applies to salary the same way it applies to payments for services, contracts, or rent. TDS deducted in a given month must be deposited to the IRD, typically within 25 days of month-end, filed via ETDS (electronic TDS) through the online taxpayer portal.

The monthly payroll cycle, step by step

A clean monthly payroll cycle for a Nepali employer generally looks like this:

1. Confirm each employee's SSF status and whether they contribute, since this changes their TDS calculation directly through the 1% social security exemption.
2. Calculate gross salary including base pay and any allowances or benefits, applying consistent rules for what counts as taxable salary.
3. Apply allowable deductions — SSF/EPF/CIT contributions, life and medical insurance premiums where applicable — before running the remainder through the current fiscal year's tax slabs.
4. Deduct TDS based on the current year's progressive slabs, not a prior year's table, and net out any applicable rebates such as the female employee rebate.
5. Deposit SSF contributions — both employer and employee portions — and deposit withheld TDS to the IRD, typically within 25 days of month-end for TDS, filed via ETDS.
6. Record everything in a form that supports both monthly reconciliation and the annual tax payment certificates employees will need for their own filing.

Running this cycle correctly every month, for every employee, is exactly the kind of repetitive, detail-heavy process that our outsourced payroll service is built to handle — so a growing team doesn't rely on one person catching every slab update and every mid-year salary change by hand.

A worked example: SSF contributor vs. non-contributor

Take two employees, each earning NPR 12,00,000 gross annually under the FY 2083/84 slabs. The first contributes NPR 1,00,000 a year to SSF, well within the combined SSF/EPF/CIT deduction cap of the lower of NPR 5,00,000 or one-third of total income. Their taxable income after the deduction is NPR 11,00,000, and because they're an SSF contributor, the first NPR 10,00,000 slab is exempt entirely rather than taxed at 1%, leaving only the remaining NPR 1,00,000 taxed at 10% — a total of NPR 10,000. The second employee, with the same NPR 12,00,000 gross but no SSF contribution and no deductions, pays NPR 10,00,000 at 1% (10,000) plus NPR 2,00,000 at 10% (20,000), for a total of NPR 30,000. Same gross salary, three times the resulting tax bill — purely because of SSF status and the associated deduction. This is exactly why an employer's payroll system needs to track SSF status accurately per employee rather than applying a blanket calculation across the whole team.

Where payroll errors actually happen

The most common issues we see, across many different employers and team sizes: applying last year's tax slabs after a budget change, miscalculating SSF contributions when an employee's salary changes mid-year, and inconsistent treatment of allowances and benefits that should or shouldn't be included in taxable salary. Each of these tends to be a small, easily explainable error in isolation — a payroll spreadsheet that wasn't updated after the budget, a formula that didn't recalculate SSF after a raise took effect mid-month — but because payroll runs every single month for every employee, a small error compounds fast. A slab calculation error that persists for six months affects six months of withholding for every affected employee, discovered all at once during annual reconciliation rather than caught and corrected the month it happened.

Deductions that reduce taxable salary

Before TDS is calculated, several deductions can reduce an employee's taxable salary, and payroll needs to apply them consistently to avoid over-withholding. SSF, EPF, and CIT contributions combined are deductible up to the lower of NPR 5,00,000 or one-third of total income. Life insurance premiums are deductible up to NPR 40,000, and medical insurance premiums up to NPR 20,000. Female employees also receive a 10% rebate on computed tax — a rebate that, as of FY 2083/84, applies to female employees generally rather than being conditioned on marital status the way it was under the previous slab structure. Payroll systems that don't correctly apply these deductions and rebates systematically over-withhold from employees who are entitled to them, creating a downstream reconciliation problem at year-end even though the employer's intentions were never to over-tax anyone.

Employee documentation

Employees need annual tax payment certificates documenting what was deducted on their behalf — necessary for their own personal tax filing. Employers who don't issue these promptly create a downstream problem for their staff at filing time. This certificate is the employee's evidence that TDS was actually withheld and deposited on their behalf, which they use to claim credit for that amount when filing their own annual return — without it, an employee has no clean way to reconcile what they earned against what was already paid in on their behalf, and may end up either over- or under-reporting their liability. Losing track of these certificates on the employer's side is a common source of reconciliation headaches at year-end, particularly for a growing team where turnover means some certificates need to be issued for employees who've already left.

Why this is worth outsourcing as you grow

A single employee's payroll is manageable by hand. A growing team, with varying salaries, benefits, and SSF timelines, is where manual payroll starts producing quiet errors that surface as compliance gaps months later. Outsourced payroll processing exists specifically to keep this correct without it consuming a founder's time every month. Not every business needs a full-time in-house accountant on day one — dedicated or shared accounting staff and outsourced monthly payroll processing scale to what a business actually needs at its current size, rather than forcing a founder to choose between doing payroll personally or hiring someone full-time before the team is large enough to justify it.

Setting up payroll correctly for a new employee

Getting payroll right for a new hire from their first pay cycle avoids a lot of the reconciliation work that shows up later. That means confirming their PAN is on file before the first salary run, establishing their SSF status and whether they'll be contributing from day one rather than mid-year, and getting a clear, documented understanding of their salary structure — base pay versus allowances versus any benefits — so the taxable-versus-non-taxable treatment is consistent from the start rather than decided ad hoc each month. A new employee whose SSF status or deduction eligibility isn't settled in their first pay cycle often ends up needing a retroactive correction once it is settled, which is more work for payroll than simply confirming the details upfront would have been.

Year-end reconciliation

However carefully payroll is run each month, year-end is where everything gets checked against the full picture: total salary paid, total TDS withheld and deposited, total SSF contributed, and whether any employee's actual annual tax liability under the final applicable slabs differs from what was withheld across the year. This reconciliation is also where errors that quietly persisted for months — an outdated slab table, a missed mid-year salary adjustment — become visible all at once, which is exactly why catching them monthly is preferable to discovering them here. For employees, any shortfall between what was withheld and what they actually owe becomes part of their own annual return; any employer-side error in TDS deposited becomes part of the employer's own reconciliation with the IRD. Keeping monthly payroll records clean and consistent throughout the year is what makes this a straightforward year-end check rather than a multi-week reconstruction project.

Common mistakes to avoid

• Carrying forward last year's tax slabs after a budget change. Slab tables shift periodically through the annual budget, and payroll needs to be updated the moment new slabs take effect, not weeks or months later.
• Not recalculating SSF and TDS after a mid-year salary change. A raise, promotion, or role change mid-year needs its payroll impact recalculated immediately, not carried forward at the old rate.
• Inconsistent treatment of allowances and benefits. Whether a specific allowance counts as taxable salary needs a consistent rule applied across the whole team, not a case-by-case judgment call each pay cycle.
• Delaying annual tax payment certificates. Employees depend on these for their own filing — a late certificate creates a downstream problem for staff, not just an administrative delay for the employer.
• Treating SSF registration as bundled into company or PAN registration. It's a separate registration step that needs to happen before SSF-based payroll can legally run.

Frequently asked questions

Do I need to register separately for SSF, or is it part of company registration?

Separately. SSF registration is a distinct step from PAN and company registration, and it needs to happen before an employer can legally run payroll under the SSF framework at all.

How does SSF contribution affect an employee's income tax?

If an employee contributes to SSF, the 1% social security portion of the first income tax slab is waived entirely, and the SSF contribution itself is deductible from taxable income up to the combined SSF/EPF/CIT cap — both effects reduce the employee's tax bill compared to a non-contributing employee at the same salary.

How often do income tax slabs change, and how does that affect payroll?

Slabs are periodically revised through the annual national budget — FY 2083/84 brought a significant reset, for instance. Payroll calculations need to be checked against the current fiscal year's rates each time a budget changes, not carried over unchanged from the previous year's table.

When does an employer need to deposit TDS withheld from salaries?

Typically within 25 days of month-end, filed via ETDS through the online taxpayer portal — the same monthly rhythm that applies to TDS withheld from other categories of payment.

What documentation do employees need for their own tax filing?

An annual tax payment certificate from their employer, documenting what was deducted on their behalf during the year — necessary to claim credit for that amount when filing their own personal return.

Does the female employee tax rebate still require unmarried status?

No — as of FY 2083/84, the 10% rebate applies to female employees generally, since the slab structure no longer distinguishes by marital status the way the previous table did before this year's change.

At what point should a growing business outsource payroll instead of handling it in-house?

There's no fixed employee count that triggers it, but manual payroll tends to start producing quiet errors once a team has varying salaries, benefits, and SSF timelines to track simultaneously — outsourced payroll processing exists specifically to keep that correct without consuming founder time every month.

What should be settled before running payroll for a new employee's first pay cycle?

Their PAN on file, a confirmed SSF status and contribution decision, and a clear, documented salary structure distinguishing base pay, allowances, and any benefits — settling these upfront avoids a retroactive correction once details are confirmed mid-cycle instead.

What happens during year-end payroll reconciliation?

Total salary paid, TDS withheld and deposited, and SSF contributions are checked against what employees actually owed under the applicable slabs for the year. Errors that persisted quietly for months — like an outdated slab table — tend to surface here if they weren't caught earlier, which is why clean monthly records matter.

Bottom line

Payroll in Nepal is a recurring monthly compliance exercise, not a one-time setup — SSF registration and contributions, TDS calculated against the current year's slabs, correct treatment of deductions and rebates, and timely employee documentation all need to happen correctly every single pay cycle. A single employee's payroll is manageable by hand; a growing team is where small, repeatable errors start compounding into real compliance gaps, which is exactly the point at which outsourcing the process tends to pay for itself. Get SSF status, slab calculations, and documentation right from each employee's first pay cycle, and year-end reconciliation becomes a routine check rather than a scramble to explain months of quietly accumulated errors across the whole team.
