| 3 | Over 360 to 720 | Between 30 and 60 | 20% |

Eligibility and conditions for tax incentives
Decree 20 supports experts and scientists working in innovative startup businesses. The incentives include: exemption from 100% tax for the first two years (24 months) and a reduction of 50% tax for the following four years (48 months).

The tax exemption period is calculated continuously from the month in which the preferential income is generated. Circular No. 561/TPHCM-QLDN3 notes that even with the application of the new 5-tier tax schedule, the calculation of the tax exemption must still adhere to the principle of allocating the actual income proportionally if an individual works in multiple places.

- Tax exemption amount = (Total tax calculated on total income) × (Preferential income / Total taxable income).
- Tax reduction amount = 50% × (Total tax calculated on total income) × (Preferential income / Total taxable income).
This approach ensures fairness and encourages experts to contribute to research. Official document No. 561/TPHCM-QLDN3 confirms the tax rate framework applied in the above-mentioned "Total Tax" calculation formula.
