Frequently asked
- Q. If rental income β€ β©20M, is separate taxation always better?
- A. Not always. With low other income and a 6% / 15% bracket, comprehensive can be better. The tool simulates both and recommends.
- Q. Whatβs the deemed-rent formula?
- A. (Total deposits β β©300M) Γ 60% Γ the prescribed deposit rate (2.9% for 2026). Not applied below 3 homes or below β©300M.
- Q. Penalties for not registering as a landlord?
- A. A 0.2% surcharge applies on unregistered rental income, and the expense deduction drops from 60% to 50% under separate taxation. Both are auto-applied.
- Q. Can I file with the result directly?
- A. Itβs decision-support only. For actual filing, use Hometaxβs comprehensive-income simulation or consult a CPA.
