From bd-income-tax
Compute and explain Bangladesh individual (personal) income tax under the Income Tax Act 2023 and the current Finance Act — tax slabs, tax-free thresholds (including women, senior citizens, persons with disabilities, third-gender, freedom fighters), salary exemption, the Section 78 investment rebate, minimum tax, net-wealth surcharge, TDS credit, filing/PSR rules, Tax Day, and penalties. Use this skill whenever the user mentions Bangladesh income tax, NBR, TIN, e-return / etaxnbr, an assessment year vs income year, salary tax computation, investment rebate, surcharge, or asks to calculate an individual's Bangladeshi tax for any year — even if they don't say "skill".

Compute and explain **personal/individual** Bangladesh income tax. Scope is individuals
Compute and explain personal/individual Bangladesh income tax. Scope is individuals
only — not corporate tax or VAT. All arithmetic is done by scripts/tax_calc.py; never
hand-calculate.
Bangladesh fiscal/income year runs 1 Jul – 30 Jun; the income year maps to the following assessment year (AY).
| Income year | Assessment year | Governing law | General threshold |
|---|---|---|---|
| 1 Jul 2024 – 30 Jun 2025 | AY 2025-26 | Finance Ordinance 2025 | 350,000 |
| 1 Jul 2025 – 30 Jun 2026 | AY 2026-27 (primary) | ITA 2023 + Finance Bill 2026 | 375,000 |
Read only the file for the relevant year, plus shared files as needed:
references/ay-2026-27.md — AY 2026-27 slabs, thresholds, salary cap, rebate, min tax, surcharge.references/ay-2025-26.md — prior-year figures (note the 5% slab still applies that year).references/procedure.md — the ordered 9-step procedure + worked example.references/filing.md — TIN, PSR, e-return, forms, Tax Day, penalties.references/sources.md — source keys; cite the source for every rate/threshold.Never compute tax yourself — run the bundled scripts/tax_calc.py. When the skill is installed
as a plugin its files sit in a version-numbered folder, so reference the script by its full
path rather than cd-ing into that folder (this keeps the command stable across versions). Use
$CLAUDE_PLUGIN_ROOT when it is set:
python3 "$CLAUDE_PLUGIN_ROOT/skills/bd-income-tax/scripts/tax_calc.py" --year 2026-27 --category general --salary 800000 [...]
If $CLAUDE_PLUGIN_ROOT is not set, run python3 scripts/tax_calc.py … from this skill's own
directory. Or import compute_tax(...). Key inputs: --year, --category
(general|female|senior|disabled|third_gender|freedom_fighter|july_warrior), income heads
(--salary gross, --rent, --agriculture, --business, --capital-gains, --financial,
--other), --investment, --location (AY 2025-26 min tax: dhaka_ctg_cc|other_cc|other),
--new-taxpayer, --net-wealth, --extra-car, --big-house, --tds, --filed-late,
--gross-receipts. Run --selftest to confirm the four canonical results.
The script returns every intermediate (threshold, salary exemption, total income, slab breakdown, gross tax, rebate + its three candidates, tax after rebate, minimum tax, surcharge, TDS credit, net payable).

**You owe about ৳15,833 in income tax — roughly ৳1,320 a month.**
Income year **1 Jul 2025 – 30 Jun 2026** → **Assessment Year 2026-27** (filed under the
Income Tax Act 2023; the 2026-27 rates come from the Finance Bill 2026, still provisional
until it is passed).

| − Tax-free third of salary (⅓, capped at 500,000) | −৳266,667 |

💡 **You can pay less.** Money put into approved savings (DPS, life insurance, government
savings certificates, listed shares) comes back as a 15% tax discount. Here's how saving more
lowers this year's tax:
| If you invest in approved savings | You get back (15%) | Your tax becomes |
|---|---|---|
| ৳0 | ৳0 | ৳15,833 |
| ৳50,000 | ৳7,500 | ৳8,333 |
| ৳100,000 | ৳15,000 | ৳833 |
| **~৳106,000** | **৳15,833** | **৳0** |
Tell me your investment amount and any tax your employer already deducted (TDS), and I'll give
you the final figure.
