UK Vat change from 17.5 to 15% - How will this affect your code?

Question

The UK VAT system is changing from 17.5% to 15%. What strategies have you used in your code to store the VAT, and how will the change affect your applications. Do you store

Answer 1

I am just working on something to do this for when the rate changes back.

Which ever way you do it, there's no need to record a start and an end date in your vat table since the vat periods run directly after each other.

You can access the correct vat by doing a query like the one below, where vat_date is the start date for the VAT rate.

SELECT * FROM vat WHERE NOW() > vat_date ORDER BY vat_date DESC LIMIT 1
