UK citizens would probably save only a small amount in direct taxes , not a huge one. Based on recent reporting, the official public funding for the royal household was about £86.3 million in 2024–25, while some anti- monarchy estimates put the broader annual taxpayer cost at around £510 million once security and other indirect costs are included.

What that means per person

Using the official funding figure alone, the saving would be roughly £1–£2 per person per year for UK residents, depending on the population used. That is because the Sovereign Grant is relatively small when spread across the whole country.

If you use the larger anti-monarchy estimate, the implied saving could be closer to about £7–£8 per person per year. But that bigger figure is disputed, because it includes costs and assumptions that supporters of the monarchy say would not disappear if the monarchy were abolished.

Why the savings are disputed

Abolishing the monarchy would not automatically remove all costs tied to royal properties, security, ceremonies, or the management of Crown assets. Some reports also argue the state could lose income from the Crown Estate or other royal-linked revenue streams if the system changed.

Supporters of the monarchy say it may even be a net benefit because tourism, ceremonial value, and Crown Estate arrangements offset part of the public cost. Critics argue the hidden public costs are much higher than the headline grant.

Practical answer

The most defensible short answer is:

  • Direct tax saving: probably around £1–£2 per person per year.
  • Broader claimed saving: possibly £7–£8 per person per year , but that is controversial.
  • Biggest uncertainty: security, lost revenue, and what new head-of-state system would cost.

Bottom line

So, even if the monarchy were completely abolished, the average UK taxpayer would likely not see a dramatic tax cut. The savings would probably be modest unless the government also made major changes to security, property ownership, and the wider constitutional setup.
