9. Simple example

You run a business in Honiara with 4 employees that is registered for Sales Tax.

Monthly filing routine:

By the 14th: Submit NPF contribution schedule and payment to SINPF
By the 15th: File PAYE monthly return and remit deductions to IRD
File Sales Tax return as required by IRD

For January:

NPF due by 14 February
PAYE return due by mid-February
Sales Tax return as scheduled

Annual filing:

Form IR22 (corporate return) after year-end
PAYE annual reconciliation
Issue P10 certificates to all employees

That means you file 3 forms most months and additional forms at year-end.
