It's a good one, for a change :)
This year NISA accounts saw a fairly significant change, one that I completely missed. Ooops.
Fortunately our forum members are more competent than I am, so someone brought it up this week.
It's actually a great little change, in that it fixes something that was wrong with NISA. There's still a long way to go before the Japanese version comes even close to how good the British ISA is, but any improvement is a positive in my book.
The way NISA accounts worked until this year is that when the tax-free period was up (after five years for the regular NISA and twenty for the tsumitate), you could choose to 'roll-over' the investments into a new NISA year, but only up to the NISA limit.
For example, if you had 1.2m yen's worth of shares in the account and their value had gone up to 1.5m yen, you would only have been able to roll over 1.2m yen's worth. The remaining 300,000 yen's worth of shares would either have to be sold or moved into a taxable account.
From this year, however, you can roll over the full amount, regardless of how much it is worth. This is a pretty significant change, as it allows your NISA holdings to get bigger over time.
You can read about the changes in Japanese here.
Of course, the main issue is that regular NISA accounts are only due to exist until 2023. I am still hoping the government will extend their validity or replace them with something comparable or better.
If that happens, rest assured. You will read about it here (eventually).
