Technically NISA exists only until 2028 and we don't know if they will extend it or not (or just steer everyone into TNISA and nothing else) but you have everything else right.Viralriver wrote: ↑Mon Nov 15, 2021 7:20 am This is... really interesting, and more proof I think I didn't understand it as well as I originally thought I did. So there is no overall limit to how many years we can have a NISA account, and no limit to how much we can invest overall? The limits are just yearly limits, but over my lifetime I could have as many year/accounts as I want? I made my original decision thinking I had only 5 years or 20 years of tax-free investments so went with tsumitate, but if this is the case I can't see any benefit for the tsumitate if you are able to place 1.2m JPY in. Am I thinking correctly?
The argument of whether NISA or TNISA is "better" is something we've discussed quite extensively on this site. The fact that TNISA has 20 years tax free versus only 5 years for NISA despite the large yearly limit makes it "safer" for most people. I've done some back of the envelope math and it comes out that NISA only "wins" over TNISA if you're able to invest 1.2M directly every January. In most other cases, putting 400k into TNISA and 800k into a taxable account comes out as more optimal.
