Guide To Rule 4

Guide to Rule 4 – Summary

  • If you win a bet on a horse, a Rule 4 deduction will be applied if there was a Non Runner in the race after you placed your bet
  • There is no Rule 4 deduction if the Non Runner was declared before you placed your bet
  • The size of the deduction depends on the odds of the Non Runner (or Non Runners if there’s more than 1)
  • Antepost bets are not subject to Rule 4 bets, but you’ll get no refund if your horse is a Non Runner

What is a Rule 4?

Put simply, the Tattersalls Rule 4 is a deduction made to all winning returns earned from bets placed before a non-runner has been declared. This rule only comes into effect if the withdrawal follows the official declarations having been made and only affects those who have taken their horse’s price i.e. not bet at Starting Price (SP). The ‘official declarations’ for each field are usually made 24 hours before each race though this can vary with some being made a full two days prior.

When will there be no Rule 4 on my bet?

“Rule 4” will not affect those placing Ante Post wagers or taking a selection’s SP (starting price). You will also be free from a Rule 4 hit if you placed your bet following the removal of all non-runners. This is due to the fact that bookmakers will readjust their early prices once a horse has been taken from the field, meaning that the price you have taken will already have had the removal of the non-runner factored in.

There is no flat charge to be applied to winnings; instead the amount depends upon the price of the non-runner – the shorter the odds, the larger the deduction. If there is more than one Non Runner after you place your bet, add the deductions together to find the total deduction on your winnings. A full list of deductions can be found below.

Why is the rule enforced?

In short, Rule 4 maintains a level of fairness, protecting the integrity of bookmakers’ prices through allowing for these late withdrawals.

Imagine for a second that you had backed a horse at the fixed price of 10/1 only for the evens favourite to be pulled from the field with a couple of hours remaining. You would have received a huge price considering the horse expected to win the race was no longer running! With Rule 4 however, the deduction is made to bring your price in line with the price the bookmakers would have offered you had they known that the Non Runner wasn’t going to run.

In contrast, however, let’s say that instead of the race having this evens favourite removed, it was the 33/1 outsider that failed to make it to the start line. As the removal of this horse will have had a lesser effect on the prices of its fellow runners, no Rule 4 is applied to returns. This makes it much fairer than a flat fee.

The following list sets out the possible deductions you may face for backing a horse after the official declarations have been made but prior to a late non-runner being announced. Bear in mind that these charges only affect your winnings and not the stake that will be returned.

Guide to Rule 4 Possible Deductions

Price at withdrawal and amount decided in the pound from winnings:

1/9 or shorter = 90p
2/11 to 2/17 = 85p
1/4 to 1/5 = 80p
3/10 to 2/7 = 75p
2/5 to 1/3 = 70p
8/15 to 4/9 = 65p
8/13 to 4/7 = 60p
4/5 to 4/6 = 55p
20/21 to 5/6 = 50p
Evens to 6/5 = 50p
5/4 to 6/4 = 40p
13/8 to 7/4 = 35p
15/8 to 9/4 = 30p
5/2 to 3/1 = 25p
10/3 to 4/1 = 20p
9/2 to 11/2 = 15p
6/1 to 9/1 = 10p
10/1 to 14/1 = 5p
Over 14/1 = No deduction

It is worth remembering that the chances of getting a deduction at the top end of this scale are slim, and it is far more common to have a 5p, 10p or 15p Rule 4 than it is to have a 50p or 60p Rule 4.

Also, no Rule 4 deduction can exceed 90p in the pound so even if you stake money before two or more short price horses are withdrawn, though this is ridiculously unlikely, you will never be hit with a charge above this threshold.

Some bookmakers also choose to forgo the 5% deduction for withdrawn horses with odds of between 10/1 and 14/1 (inclusive), so make sure you check out the terms and conditions of your turf accountant!
