This is the info I have on childcare vouchers.
If you work for yourself through a limited company then you can set up a childcare voucher scheme. You can either pay yourself vouchers in addition to any salary you're drawing (even if you aren't drawing any!) or, if you pay yourself enough, you can have vouchers through salary sacrifice.
What?s the difference between a "Salary Sacrifice"
scheme and an ?Addition to Salary" scheme?
In a ?Salary Sacrifice? scheme, employees agree to reduce their existing salary in exchange for receiving childcare vouchers. The employer and employee enter into a Salary Sacrifice Agreement and the employer then amends the payroll to reflect the change in salary. Salary Sacrifice schemes need to be approved by the Inland Revenue.
In an ?Addition to Salary? scheme, employees receive
childcare vouchers on top of their salary. The vouchers are still tax-freeand NI-free but, unlike Salary Sacrifice schemes, there is no need to seek Inland Revenue approval. As long as the vouchers are kept within the prescribed limits (£55 a week or £243 a month), they do not have to be declared on P11D forms.
For owners of small businesses who are able to amend
their salary as they wish, Salary Sacrifice schemes and Addition to Salary schemes can provide identical savings.
Hope this helps,
