If the company has received any schedular payments, Inland Revenue will send you a summary of income (previously known as summary of earnings).
Add up the total tax withheld and all the gross payments shown on the summary of income and write the totals in Boxes 12A and 12B.
The summary of income form may not contain all the company’s earnings information. If any details are missing, please include them at Question 12.
If the company received a payment with no tax deducted, include the gross amount in Box 12B.
