Determination of code
Determination of code by Inland Revenue13
The Inland Revenue must determine the code for use by an employer in respect of an employee for a tax year.
Matters relevant to determination of code14
1
If the Inland Revenue determine a code under this regulation, they must have regard to the following matters so far as known to them—
a
the reliefs from income tax to which the employee is entitled for the tax year in which the code is determined, so far as the employee’s title to those reliefs has been established at the time of the determination;
b
any PAYE income of the employee (other than the relevant payments in relation to which the code is being determined);
c
any tax overpaid for any previous tax year which has not been repaid;
d
any tax remaining unpaid for any previous tax year which is not otherwise recovered;
e
any tax repaid to the employee in excess of the amount properly due to the employee which may be recovered as if it were unpaid tax under section 30(1) of TMA22 (recovery of overpayment of tax etc) and which is not otherwise recovered;
f
unless the employee objects, any other income of the employee which is not PAYE income; and
g
such other adjustments as may be necessary to secure that, so far as possible, the tax in respect of the employee’s income in relation to which the code is determined will be deducted from the relevant payments made during that tax year.
2
If the Inland Revenue determine the code before the beginning of the tax year for which it is determined, the Inland Revenue—
a
must have regard to any expected change in the amount of any relief referred to in paragraph (1)(a), but
b
may disregard any such relief if they are not satisfied that the employee will be entitled to it for the tax year for which the code is determined.
3
Paragraphs (1)(c) and (d) are subject to regulations 186 and 187 (recovery and repayment: adjustment of employee’s code).
Flat rate codes15
1
The Inland Revenue may determine that the code for use by an employer in respect of an employee for a tax year is the higher rate code, if they have reason to believe that the employee will be chargeable at the higher rate on all or a substantial part of the employee’s relevant payments.
2
The Inland Revenue may determine that the code for use by an employer in respect of an employee for a tax year is the basic rate code, if they have reason to believe that the employee will be chargeable at the basic rate on all or a substantial part of the employee’s relevant payments.
3
The Inland Revenue may determine that the code for use by an employer in respect of an employee for a tax year is the nil tax code, if—
a
the employee’s PAYE income will be taken into account as taxable income other than PAYE income in any assessment,
b
the Inland Revenue are not satisfied that the employee’s income will be chargeable, or
c
the Inland Revenue have reason to believe that the employee will be entitled to a deduction under Chapter 6 of Part 5 of ITEPA (deductions from seafarers' earnings) in respect of the employee’s PAYE income or so much of it as remains after any deductions under section 592(7) or 594(1) of ICTA23 (exempt approved schemes and exempt statutory schemes).
4
References in this regulation to an employee’s relevant payments, PAYE income and income are references to the payments or income in respect of which the employee’s code is being determined for the purposes of the employment in question.
Continued application of employee’s code16
1
If the Inland Revenue determine that the code for use by an employer in respect of an employee for a tax year remains the same as at the previous 5th April, the Inland Revenue need not issue a code to the employer.
2
If for any tax year the employer does not receive a code for an employee who was in that employer’s employment on the previous 5th April, the code which applied on that date is treated as having been issued by the Inland Revenue for the tax year in question.
Notice to employee of code17
1
The Inland Revenue must give notice to an employee of the code which they have determined for use in respect of that employee for any tax year.
2
But notice need not be given if—
a
the code for use in respect of the employee remains the same as at the previous 5th April; or
b
the change in the code is solely because of an alteration or proposed alteration in the rates of any of the personal reliefs allowable under sections 257 and 257A of ICTA24 (personal allowance and married couple’s allowance) or in the tax tables.
