Yes, easier paperwork and immikgration control. If you keep the 800k baht in a fixed account – for example 12-months – you get best bank interest, which you can withdraw once a year, so you always have a clean 800k baht balance. Interest rate can be around 1.5% p.a. minus 15% withheld tax. I've been using retirement extension for m18 years. I've been writing off my 800k baht as price for my prolonged stay in Land-of-Smiles, and deposit the paid interest in a separate "rainy day account", so I have extra access to fund, should something unexpected happen. In time the funds can – with help from interest's interest – grow to an useable amount for unforseen iuncidents.
