Holding tax in 4 steps

The Net Annual Value formula city corporations use — decoded for owners.

📅 Jun 20, 2026⏱ 6 min read🏷 Tax · Holding tax

Every year, city corporations assess buildings for holding tax. Most owners pay whatever the notice says. Here's the formula — and how to check their math.

The Net Annual Value pipeline

For a wholly let-out building, the assessment works like this:

  1. Gross Annual Rental — all active lease values summed over 12 months.
  2. − Maintenance Allowance — two months of rent (≈16.67%) is deducted.
  3. − Mortgage Interest — annual interest payable to a scheduled bank or BHBFC, if the property is mortgaged.
  4. = Net Annual Value — on this figure the corporation applies its percentage rate (e.g. 8% in Dhaka North).
Worked example: a Banani office floor renting at ৳3,80,000/mo → Gross ৳45,60,000 → − allowance ৳7,60,000 → − mortgage interest ৳18,00,000 → NAV ৳20,00,000 → at 8% ≈ ৳1,60,000/yr.
