About GajiPas

GajiPas exists because payroll numbers are too important to be taken on trust — including ours.

Who operates this site

GajiPas is built and operated by Abdul Hannan, AH Digital Studio, based in Pakistan. The site serves two audiences from one rule engine: employees in Indonesia (Bahasa Indonesia, root of the site) whose take-home pay runs on TER, BPJS and the December Pasal 17 reconciliation — and employees in Pakistan (English, the /pk/ section) whose payslips run on the FBR salaried slabs and EOBI. The operator is not affiliated with DJP, BPJS Kesehatan, BPJS Ketenagakerjaan, FBR, or EOBI; those institutions publish the rules, and this site computes with them.

The one design decision that matters

On this site, rules are data. Every tax table, cap, rate and bracket lives in a versioned rule file that records the official source it was transcribed from, the date the rule takes effect, and the date it was last verified against that source. The calculators contain formulas only — no tax figure is typed into code. Reference pages (the TER tables, the TY2027 slabs) are rendered from those same files, so the documentation cannot drift away from the calculator. Every result prints its rule source and verification date underneath, and the Methodology page publishes the full inventory, including the calendar of scheduled re-verifications.

This discipline exists because the failure it prevents is common and quiet: a well-meaning site whose guide says one rate while its calculator uses another, or whose table is two Finance Acts old. When we found exactly those failures in existing tools during research — including a popular calculator computing EOBI as 1% of the user's own salary — we decided the verification had to be structural, not a promise.

What GajiPas is not

It is not an official service, not a payroll provider, and not tax advice. Results are computations from the published rules under stated assumptions (shown on each tool); your employer's payroll, applying your complete record, is the operative calculation, and your tax office's assessment is the final one. Where a genuinely contested point exists — the two EOBI bases are the standing example — the site prints both figures and says why, instead of quietly picking one.

Corrections

If you find a figure on this site that disagrees with an official source, that is the most valuable message you can send us. Corrections are made in the rule file (so every page and calculator updates together), the verification date is re-stamped, and the change is visible in the file's history. Contact details are on the Contact page.
