As seen in a reddit thread, this is the first I’ve heard (good or bad) about the Help to Save scheme.
Someone linked the government site quoting:
About Help to Save
Help to Save is a savings scheme backed by HM Treasury, so your savings are 100% secure.
You can only open an account if you’re receiving Working Tax Credit and meet all the eligibility criteria.
If you’re eligible for an account, you could earn a 50% bonus on the money you’ve paid in.
If you pay in £2,400 over 4 years and don’t make any withdrawals, you will earn the highest possible bonus of £1,200. All bonus money is tax-free.
