218Calculation of earnings rate for a tax year
(1)For any tax year the earnings rate for an employment is to be calculated as follows—
Step 1
Find the total of the following amounts—
(a)the total amount of the earnings from the employment for the year within Chapter 1 of this Part,
(b)the total of any amounts that are treated as earnings from the employment for the year under the benefits code (see subsections (2) and (3)),
(c)the total of any amounts that are treated as earnings from the employment for the year under Chapter 12 of this Part (payments treated as earnings), and
(d)in the case of an employment within section 56(2) (deemed employment of worker by intermediary), the amount of the deemed employment payment for the year (see section 54),
excluding any exempt income.
Step 2
Add to that total any extra amount required to be added for the year by section 219 (extra amounts to be added in connection with a car).
Step 3
Subtract the total amount of any authorised deductions (see subsection (4)) from the result of step 2.
Step 4
The earnings rate for the employment for the year is given by the formula—
where—
R is the result of step 3,
Y is the number of days in the year, and
E is the number of days in the year when the employment is held.
(2)Section 216(1) (provisions not applicable to lower-paid employment) is to be disregarded for the purpose of determining any amount under step 1.
(3)If the benefit of living accommodation is to be taken into account under step 1, the cash equivalent is to be calculated in accordance with section 105 (even if the cost of providing the accommodation exceeds £75,000).
