Key Tax Dates and Deadlines
UK tax deadlines depend on the tax, business structure and accounting period. This guide explains the common patterns and why HMRC and gov.uk should always be checked for current dates.
Quick answer
What are the key takeaways?
Different taxes have different filing and payment dates.
Key takeaways
Different taxes have different filing and payment dates.
Self-Assessment, VAT, PAYE, Corporation Tax and Companies House deadlines should be tracked separately.
Company deadlines often depend on the accounting period rather than the calendar year.
Use gov.uk, HMRC notices and your accountant's reminders as the source of current deadlines.
Which tax deadlines should individuals know about?
Individuals commonly need to track Self-Assessment registration, return filing and payment dates. These are especially important for sole traders, landlords and people with untaxed income.
HMRC can charge penalties and interest when deadlines are missed, so check the current gov.uk guidance if you are unsure whether a return or payment is due.
Which deadlines matter for limited companies?
Limited companies usually need to track accounts, Confirmation Statements, Corporation Tax registration, Corporation Tax payment and Corporation Tax return filing.
Some company deadlines are based on the accounting period or incorporation date, so copying another company's dates can be misleading.
How do VAT and PAYE deadlines work?
VAT deadlines usually follow the VAT return period shown in the business's HMRC account. PAYE deadlines depend on the payroll reporting and payment cycle.
Making Tax Digital and payroll reporting mean late or incorrect digital submissions can create avoidable compliance issues.
How can you avoid missing HMRC deadlines?
Keep a single deadline calendar, update it when HMRC changes a period or status, and give your accountant records well before the filing date.
Countify helps clients turn deadlines into a planned workflow, with reminders linked to the records needed for each return.
