# Bangladesh individual income tax
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.
## 1. Determine the assessment year first
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 |
- **Default:** if the user gives a current salary/income with no year, assume income year
FY 2025-26 → **AY 2026-27**.
- **State the assessment year and governing law at the top of every answer.**
- Note that FY 2026-27 is still a **Finance Bill** (placed 11 Jun 2026) until gazetted as the
Finance Act 2026 — say so.
## 2. Read the right reference file (progressive disclosure)
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` — sour
