The most important recent changes that could affect your tax bill. We monitor HMRC and GOV.UK so you don't have to.

Read our guideHMRC reports that 86,270 people filed on Easter Monday alone (6 April), with almost 740,000 filing in April overall. Filing early means knowing your bill sooner and potentially receiving any refund faster.
Source: GOV.UKNearly 340,000 people paid their Self Assessment bill via the HMRC app since April 2025 — a 65% rise year-on-year. HMRC is pushing digital-first, with the 2024/25 deadline of 31 January 2026 now passed.
Source: GOV.UKResearch shows that despite MTD for ITSA affecting an estimated 2.9 million individuals, only 30% are aware of the reforms. Those affected must register, choose compliant software, and begin quarterly reporting.
Read our MTD guideThe 2025/26 tax year began on 6 April 2026. Over 12 million taxpayers are expected to submit returns. Filing early can mean faster refunds — and spreading payments via HMRC's budget plan reduces January bill shock.
Check deadlinesHMRC's new penalty regime is now fully in force. Points accumulate for late submissions — reaching a threshold triggers a £200 fine. Unlike the old £100 flat penalty, this system escalates quickly for repeat offenders.
Understand penaltiesPlain-English guides written by our qualified consultants — covering everything from MTD to HMRC compliance reviews.

I'd been overpaying for three years. TaxCompare recovered £4,200 in overpayments and now handle everything for me. Absolutely brilliant — worth every penny.
When HMRC opened a compliance review I was terrified. TaxCompare handled everything professionally and it was resolved with no additional payment. Cannot recommend highly enough.
The free call lasted 40 minutes and gave me more useful advice than my old accountant had in three years. Switched everything over immediately and haven't looked back.
