NASFund Deadlines 2026: Every Employer's Cheat Sheet

If you employ anyone in Papua New Guinea who earns K1,250 or more a month, you are statutorily required to contribute to a superannuation fund — most commonly Nasfund. The mechanics are simple. The penalties for missing the deadline aren't. Here's the cheat sheet every SME owner should keep close.

The contribution split

• Employee: 6% of gross pay (the legal minimum). Deducted from each pay run.
• Employer: 8.4% of gross pay. Paid in addition to wages, not from them.
• Total to Nasfund per employee: 14.4% of their gross.

Employees can opt to contribute more (Voluntary Member Contribution). The 8.4% employer rate is fixed and cannot be reduced.

The 21st-of-the-month rule

Nasfund contributions for any given month are due by the 21st of the following month. So:

What if you miss it?

Late contributions attract a penalty of 2% of the unpaid balance per month. That sounds small but compounds quickly. K20,000 of unremitted contributions for six months means K2,400+ in penalty interest on top of the original liability.

Beyond the penalty, Nasfund can recover unpaid contributions as a civil debt through the courts. The director of a company can be held personally liable for unremitted employee contributions — this is one of the few areas of PNG law where the corporate veil offers no protection.

The actual filing — what Nasfund needs from you

Each month you file a contribution return alongside the payment. The return must list every member who contributed in that month, with:

• NASFund member number
• Surname and given names
• Date of birth (yes — this is why TeebeePay asks for it on employee setup)
• Gross pay for the month
• Employee 6% contribution
• Employer 8.4% contribution
• Total per employee

Nasfund accepts the return in their standard XLSX template, which is what TeebeePay produces automatically each month for our clients.

The 'NCSL' moniker — what it is

You'll see Nasfund returns sometimes labelled "NCSL". That's the legacy name — the National Contribution to Superannuation Levy. Nasfund renamed but many bookkeepers and templates still use NCSL. Both refer to the same statutory contribution.

One trap to know about

Allowances (housing, vehicle, meals, etc.) are part of gross for Nasfund purposes if they're paid in cash. A taxable benefit-in-kind (e.g. the employer providing a company-owned vehicle) is added to gross for SWT but is generally not part of the Nasfund contribution base — there's no cash value flowing through the payroll. Getting this distinction wrong is one of the most common audit findings.

How TeebeePay handles it

TeebeePay tracks every contribution every fortnight and at month-end generates the Nasfund return XLSX plus the payment summary, ready to upload. We send you a reminder five business days before the 21st of every month so the deadline never sneaks up.

If you're managing Nasfund returns by hand right now, you're spending two to three hours a month on a process that can be reduced to two minutes. It's also the single most common place we see SMEs get penalty notices — almost always because the spreadsheet got moved, or the bookkeeper forgot, or the year-end rollover wasn't done. Worth handing off.
