Submit your previous tax-year return online. Applies if HMRC has told you to file, or you were self-employed with gross income over £1,000, a business partner, had untaxed income such as rent, owed Capital Gains Tax or the High Income Child Benefit Charge. Being a company director is not on its own a reason, and there is no longer a PAYE-only income threshold: use HMRC’s Check if you need a tax return tool.
Miss it: Automatic £100 fine on day 1, daily £10 fines after 3 months (max £900), then 5% of tax owed at 6 and 12 months.
If you owed more than £1,000 last year, HMRC asks for half of next year’s estimated tax in advance, due the same day as your return.
Miss it: Interest charged at Bank of England base rate + 4% (7.75% from 9 January 2026; current rate on GOV.UK). No automatic fine but interest accrues daily.
Many countries require 6 months’ passport validity from date of entry. Renew well before expiry — HMPO standard turnaround is 3 weeks but can be longer in summer.
Miss it: Refused boarding on flights to most non-EU destinations. Renewal still possible but priced higher for fast-track.
Required from the third anniversary of first registration (or first anniversary for some categories). Can be done up to 1 month early without losing the renewal date.
Miss it: Driving without a valid MOT can mean a fine of up to £1,000, and an insurer may refuse or reduce a claim.
Insurer must send renewal notice at least 21 days before renewal date. You can switch any time before then.
Miss it: Auto-renewal at the new (usually higher) price. Average loyalty markup was banned for FCA-regulated insurers in 2022 — check FCA pricing rules apply.
£50 online (£110 on paper) since 1 February 2026. Due once a year on the anniversary of incorporation. Companies House sends reminders 2–3 weeks before.
Miss it: Companies House can strike the company off the register — assets become bona vacantia (Crown property).
Pay within 14 days to halve the fine, or appeal within 28 days. If rejected, escalate to a Notice to Owner, then to the Traffic Penalty Tribunal (or London Tribunals).
Miss it: Full PCN due. Continued non-payment triggers debt registration and bailiff action.
Appeal to the operator first. If rejected, escalate to POPLA (British Parking Association) or IAS (International Parking Community) within 28 days of the rejection.
Miss it: Operator can pursue through county court (CCJ risk). Defending is possible but harder.
After your landlord (council or housing association) gives a final response, you have 12 months to escalate to the Housing Ombudsman. Repairs, mould, complaints handling.
Miss it: Ombudsman won’t investigate. Some councils require ALL complaint stages exhausted first — check before missing the deadline.
