Three more tools, three more countries: Bangladesh's new tax slabs, Sri Lanka's take-home pay and the hidden GPS in your photos

Some tools answer a question you ask once a year, when the tax return is due. Some answer a question you never thought to ask at all — like what your photo tells a stranger about where you were standing when you took it. This week I added three of both kinds to RozKaTool — free, no sign-up, everything runs in your browser — and each one reaches a different corner of Asia.

RozKaTool is now at 76 free tools, and the series keeps spreading: Nepal, Thailand, Bangladesh, the Philippines, Sri Lanka, Vietnam, Indonesia and Malaysia so far.

1. Bangladesh: a third of your salary is exempt before the slabs even start

Bangladesh rewrote its personal income tax for income year 2025-26 under the Finance Act 2026, and the headline detail is one most people miss: a salaried employee is exempt on one-third of their salary, capped at ৳5,00,000 — before any slab is applied. The tax-free limit is ৳4,00,000 for a general taxpayer, ৳4,50,000 for women and senior citizens aged 65 or above, ৳5,25,000 for third-gender taxpayers and persons with disability, and ৳5,50,000 for gazetted freedom fighters.

Above the limit, the slabs run 10% on the next ৳3,00,000, 15% on the next ৳4,00,000, 20% on the next ৳5,00,000, 25% on the next ৳20,00,000 and 30% on the rest. An investment rebate — the lowest of 3% of taxable income, 15% of your allowable investment, or ৳10,00,000 — comes off the slab tax, and a flat ৳5,000 minimum tax applies once your income is above the tax-free limit, even if the slab tax is lower. Individual returns for this income year are due by 30 November 2026 (Tax Day).

Bangladesh Income Tax Calculator 2025-26 — enter your annual income, pick your category, and see the slab-by-slab tax, the rebate and the final amount. A general salaried taxpayer earning ৳12,00,000 a year gets a ৳4,00,000 salary exemption, leaving ৳8,00,000 taxable — tax of ৳45,000 for the year.

2. Sri Lanka: Rs. 150,000 a month is tax-free — and your EPF does not lower the tax

Sri Lanka's APIT (the PAYE tax your employer deducts every month) starts only after Rs. 150,000 a month — Rs. 1,800,000 a year — of personal relief. Above that, the rates for years of assessment 2025/26 and 2026/27 run 6% on the next Rs. 1,000,000, 18% on the next Rs. 500,000, 24% on the next Rs. 500,000, 30% on the next Rs. 500,000 and 36% above Rs. 4,300,000.

The detail the page gets right, and that most quick calculators skip: your 8% EPF comes out of your pay, but it is not deducted before the tax is worked out. Tax is calculated on your gross income minus the personal relief — so a calculator that subtracts EPF first will quietly understate your tax. The old 12% slab was removed in April 2025, so any calculator still using it is out of date.

Sri Lanka Income Tax Calculator 2026 — enter your gross monthly salary and see the monthly and yearly tax, the EPF deduction and your real take-home pay. On Rs. 300,000 a month, the tax is Rs. 18,500 a month and, after the 8% EPF, take-home pay is Rs. 257,500.

3. Your photo knows where you were — and it tells anyone you send it to

This one is not a calculator at all — it is a privacy tool, and it works on files, not numbers. A photo straight from your phone hides GPS coordinates, the camera model and the date it was taken inside a block called EXIF. That data travels with the photo when you share it on WhatsApp, email or a website, and someone can read your home location or your daily routine from a few photos.

The clean copy is re-drawn from the picture pixels only, so the EXIF, GPS, IPTC and XMP blocks are gone. A JPEG clean copy is re-saved at 95% quality, which is almost never visible — but the page says plainly that it is not pixel-identical. And your photo never leaves your device: the check and the cleaning both run inside your browser tab.

Remove EXIF Data from Photo — choose a photo, read the metadata report (camera, date, whether a GPS location is stored), then download a clean copy in JPEG or PNG and share that one, not the original.

What building these keeps teaching me

The payslip calculators taught me that every country writes its own small story into a salary — a third of your pay exempt here, an EPF that doesn't reduce tax there. This week taught me something wider: sometimes the story isn't a number at all. It is a hidden block inside a photo that knows where you were standing.

The rule is the same either way — start from the actual system, say where the limits are, and let the page tell the truth about what it doesn't do.

If you file a return in Bangladesh, read a Sri Lankan payslip, or share photos from your phone, try the tool for yourself and tell me if the result matches. And if there's a tool your country needs that I haven't built yet, I'd like to hear about it.
