Investment platform IG* has launched several strong deals recently, with its offer of up to £200 cashback on your investments set to close on 30 March.

New customers can get 5 per cent back up to that cap, and there aren't many hoops to jump through to qualify for the cash – but you need to squirrel away £4,000 to get the top amount.

Cashback deals are often set at 1 per cent on the value of your investments, so bagging £200 on a £4,000 deposit is still a decent return when compared with other offers like this.

For example, Freetrade* is paying 1 per cent on transfers or deposits – but you need at least £10,000 to qualify, and you'd earn just £100 on that minimum amount.

In February, the platform closed a previous deal prematurely due to 'unprecedented demand', so if you want to take this deal it's worth doing so sooner rather than later.

A separate IG deal that's paying 1 per cent on transfers is set to close on 5 April, although you can't sign up for multiple offers and must choose the one that suits you best.

How can you earn £200 from IG?

This IG deal* could net you a good amount, provided you meet the terms and conditions to qualify. Only people who have never invested in an IG account before are eligible.

You can earn the cashback when investing in any of IG's share dealing accounts. The platform offers general investment accounts, stocks and shares Isas, and self-invested personal pensions.

You need a minimum of £100 to earn the cashback, but depositing this amount would net you just £5 – so hardly worth taking up.

The offer is currently set to close on 30 March.

You'll get the cashback by 31 July, as long as you've kept an active investment portfolio from the date of your first trade until the end of June.

Finally, make sure you use the promotional code when signing up for your account.

Research your options before signing up 

It's important that you don't decide on an investment platform based on deals and incentives alone. You should make sure the provider is right for you.

For example, if a provider charges fees, these could outweigh the cashback you initially receive. 

It's positive that IG has removed its quarterly account fees for inactive accounts. However beware that it also offers riskier trading options in the form of CFDs and spread bets. In our view it's best to steer clear of these, with IG itself saying that 68 per cent of investors lose money when trading them on its platform.

Does the deal stack up?

Keep in mind that if you have a decent level of funds to transfer, the other deal IG is running at the moment* has more money on the table.

You will earn more than £200 as soon as you have more than £20,000 to transfer.

You could also consider the below deals, if you're thinking about shifting your money before the end of the tax year.

As mentioned, Freetrade is running two separate offers* – one for an Isa and one for a Sipp – both paying 1 per cent cashback on your investments, capped at £5,000 per deal. They close on 5 April.

Hargreaves Lansdown is paying between £75 and £4,000 if you have a minimum of £10,000 to invest. Again, there are two separate deals, one for an Isa* and one for a Sipp*, meaning there's up to £8,000 up for grabs. They close on 5 April.

Fidelity* is paying between £300 and £3,000 cashback when you fund an Isa or a Sipp, or both – but there's a high minimum deposit required of £50,000. This also closes on 5 April.

Finally, Interactive Investor* is paying between £100 and £3,000 cashback for opening an Isa, Sipp or general investment account with at least £20,000. This deal closes on 5 April.
