Stamp duty in Tanzania

Stamp duty is a tax on legal instruments — contracts, conveyances, leases, mortgages, powers of attorney. The standard ad valorem rate is 1% on the consideration. A schedule of fixed fees applies to non-monetary instruments.

Instruments and their duty

  • Conveyance of land or shares — 1% on the price (or market value if higher).
  • Lease — 1% on the average annual rent multiplied by the lease term in years.
  • Mortgage / debenture — 1% on the secured amount.
  • Contract — 1% on the consideration (services, supply, joint-venture).
  • Power of attorney — TZS 5,000 fixed.
  • Affidavit — TZS 1,500 fixed.

Deadlines and penalties

Stamp duty must be paid within 30 days of execution. Late payment attracts a 25% penalty per quarter of delay, capped at the value of the duty. An unstamped instrument cannot be admitted as evidence in a Tanzanian court.

How to pay

  1. Calculate duty (this tool).
  2. Generate a TRA control number on the e-stamp portal.
  3. Pay at any commercial bank or via mobile money.
