Indonesia Income Tax Tool: Plan Like a Mortgage Calculator

Indonesia Income Tax Made Simple (Mortgage Calculator Style)

Running a household in Indonesia means juggling rent, groceries, school fees, and the dreaded payslip math at the end of every month. Our Indonesia Income Tax tool helps you sort out PPh 21 in plain language, the same way a friendly mortgage calculator turns a scary loan number into something you can actually plan around. Punch in your gross salary, allowances, BPJS contributions, and dependent count, and you'll see exactly how much take-home cash lands in the joint account, what gets carved off for tax, and how to budget the rest. Whether you're a single earner supporting kids, a dual-income couple comparing offers from new employers, or grandparents helping with

Enter gross monthly income. Type in the household earner's total monthly pay before deductions, including fixed allowances and bonuses you receive regularly.
Add dependents and marital status. Pick married or single, then choose the number of children. This sets your PTKP (non-taxable income) so the math reflects your actual family size.
Include BPJS and pension contributions. Drop in your monthly BPJS Kesehatan, BPJS Ketenagakerjaan, and any pension cuts. These reduce taxable income — much like deductions on a 401k calculator.
Hit calculate. The tool runs the progressive PPh 21 brackets and shows annual tax, monthly tax, and net take-home pay instantly.
Compare scenarios. Try a raise, a side gig, or adding a baby to the family to see how your tax changes. Great for planning that next big purchase.
Save or share the result. Screenshot the breakdown for your spouse or send it to your HR team if the numbers on your slip don't match.

Domande frequenti

Is this tool accurate for 2026 PPh 21 rates?

Yes, it uses the latest progressive brackets and PTKP thresholds set by DJP, including the updated rules for tiered tax rates above IDR 5 billion annually.

Does it factor in my kids and spouse?

Absolutely. Picking your marital status and dependent count adjusts your PTKP — a married parent of two pays noticeably less than a single filer on the same salary.

Can I use this if my partner also works?

Yes. Run each salary separately to see individual take-home, since spouses generally file under separate NPWPs unless you've combined them officially.

How is this different from a mortgage calculator or auto loan calculator?

It works the same way — inputs in, clear answer out — but instead of monthly payments, it shows your monthly tax bill and net pay so you can budget around them.

Are bonuses and THR included?

You can add them as additional irregular income. The tool will roll them into the annual gross and recalculate the tax owed for that period.

Do I need to enter NPWP details?

No personal IDs needed. We don't store anything — just plug in numbers, get the result, and close the tab.

Will this replace my company's payslip?

It's a planning aid, not an official document. Use it to double-check HR's math or estimate take-home before accepting a new job offer.
