I need to write off some liabilities off the books, should I post this to General fund or equity?

You should debit the liabilities and credit other income. But if the liabilities that you want to write off was recorded by mistake (error) in previous periods then you should restate prior period financial statements and credited to retained earnings as a prior years adjustments. However, if the amount is immaterial you can recorded in the current period financials.
