New allowance is deductible from Chargeable Income effective YA2009 – YA2013.

It is capped at 50% of the first $300,000 of Chargeable Income.

RDTA Computation

Chageable income
Less – RDTA set off
—————————-
X
Less – Partial Exemption
—————————-
Net Chargeable Income (A)
====================

RDTA = 50% of A
Max – $150,000

Basic guidelines of how RDTA works
1. Compute RDTA for Year 1
2. Year 1 RDTA is available for setoff against net Chargeable Income for Year 2, 3 and 4
3. Any unutilised RDTA would be “lost” after 3 years
4. The setoff amount is the lower of RDTA OR incremental R&D expenditure by company for the year.

What is “incremental” R&D expenditure?

Example
