Investing with Stitch
You do not need to get clearance to join the SIP. Once you’ve joined the plan you can continue to invest during close periods. The SIP is a Revenue approved scheme.
You do not need to get clearance to alter your SIP contributions. You can make changes to your contributions during a close period (although this may take effect from the next accumulation period).
If you want to sell your shares, you must get clearance, though you can transfer shares from your SIP into an ISA or pension without clearance. Once you sell them, the normal rules apply.
Unfortunately there is no provision for dividend reinvestment within the SIP.
You won’t need clearance if any shares need to be sold to meet your tax obligations from that plan. If you choose to sell any of the balance of shares, you’ll need to get clearance first.
