In my experience, it pays to print out something formal stating that the business is closed and the entity is dissolving; then file whatever you need to with the Secretary of State. Then, reach out the FTB, the BOE, the IRS and anybody else you might owe money to, and see if they'll just close the records on that entity. That worked for me when I wound-down a failed C-Corp, saved me a few thousand dollars in the end (the FTB just wrote off the minimum-franchise-tax as uncollectable, etc). But getting a good tax guy is obviously a high priority as well.
