Subcontract your overflow court accounting work. Much of the accounting I do to prepare Form 1041 can also be used for the court accounting. It takes a little more time to keep records in a format compatible with both court accounting forms and tax preparation, but if I know in advance, I can avoid duplicate work.
If an estate requires an accounting for the court, I can prepare the report for you (or the PR) to file. Much of this work duplicates the bookkeeping I already had to do to prepare the fiduciary income tax return. I will work with you to avoid duplicating work as possible. It might be beneficial for me to prepare the accounting so that it can be reconciled to the tax returns.
Many trust documents require annual financial statements to be prepared. Simple trusts require that the accounting income be distributed annually. Accounting income is not an easy concept. I can prepare financial statements for a trust and show accounting income and separate shares.
I can also prepare court accountings for a conservatorship.
