Are you wondering if you'll have to pay more taxes if you live in Wales? The answer is that it depends on your residence status. If your principal residence is in Wales, then you will be subject to Welsh income tax rates. However, if you move home, either to or from Wales, and live there for more than half the year, then you will be liable for the Welsh rate of tax. If you are a PAYE taxpayer, HMRC will decide whether or not you are a Welsh taxpayer.
If you are a self-assessment taxpayer, then you will need to assess your status as a Welsh taxpayer retrospectively at the end of the tax year. You can check your tax code by checking your payment receipt or through your personal tax account. The UK government has reduced the basic, higher and additional income tax rates by 10 pence; instead, those 10 pence and any additional payments go to the Welsh government. The point at which people start paying the highest and additional rates of income tax is the same as in England and Northern Ireland.
If you have two or more places of residence in the United Kingdom during a tax year, whether or not at the same time, you should consider which of these is your “primary place of residence” at each point in the tax year. If you don't pay taxes under the PAYE system and file an annual self-assessment tax return, then you must decide whether or not you are a Welsh taxpayer (i.e. you must self-assess your status).If you can't completely avoid stamp duty rates on the second home, then you may still be able to recover some money through a tax refund. For more information about helping with municipal taxes or how to appeal a decision about reducing municipal taxes or discretionary reduction, see Help with your municipal tax: reducing municipal taxes. Your Welsh taxpayer status for a particular tax year can only be known with absolute certainty once the tax year has ended.
HMRC will change its tax code to try to ensure that the correct taxes are collected before the end of the fiscal year.
