What Date Does the Tax Year Start

How do you determine the beginning of the tax year? The UK’s fiscal year does not begin or end at the end of the calendar year. You have 12 months to settle your tax payments and return obligations, just like the new calendar year.

The tax year starts on 6th April and ends on 5th April of the following year.

Importance of tax dates

To ensure that you don’t incur extra penalties and receive any tax refunds, it’s essential to know the tax year’s dates and deadlines for your own financial planning since those under the PAYE system are only eligible for refunds for the last four years. Self-employed individuals are particularly affected by this. The self-employed are different from salaried workers—they are required to file their own taxes based on their Self-Assessment forms and pay their own taxes on the earnings based on these forms—as opposed to using PAYE (Pay As You Earn) and receiving tax forms from their employers.

If you are a salaried employee, you may need to file a tax return form if you receive additional income from investments, from oversea, or from tips or commissions in your line of work, such as when you receive additional income from tips or commissions.

Self-employed taxpayers

If you are self-employed, it is your responsibility to remember the filing and completion dates and deadlines so you do not incur late penalties and pay more taxes than you should.

Salaried taxpayers

In the case of salary earners that receive income through the PAYE system, if a tax rebate is due, you need to apply before the end of the tax year since rebates from the previous four tax years cannot be collected.

At first, it may seem like there are many dates to remember, and it might appear confusing at first since the start and close of the tax year aren’t synchronized with the calendar year. In the end, you’ll find that the process isn’t really that tricky once you’ve done a few cycles of taxes. You may want to speak with a financial advisor if you cannot remember deadlines and dates and if you have difficulty meeting them. They can help ensure that you pay and receive tax refunds accordingly!
