Do NOT keep financial these records at your residence if you are being prosecuted by the IRS!  If you put them at another location, ensure that it is not connected with your name or any identifying numbers associated with you or your address.  A friend, for instance, could keep the records for you.  That way, when the IRS does an asset search or a search for safe deposit boxes by Social Security Number, they will find nothing and can't seize anything that might damage your legal defense.

Keep electronic copies of your financial records in encrypted form on your computer so you can still organize your defense, and back them up regularly.  Keep the encrypted back-up with the hidden records in case they seize your computer also.  Microsoft Access, for instance, allows you to create an encrypted, password-protected database.  Microsoft Excel and Word, for instance, allow you to assign passwords to spreadsheets and word  processing documents so that you can't open them up without a password.  These can be very handy approaches for protecting your privacy.

Finally, NEVER, under any circumstances, admit to the existence of any kind of records to anyone.  If you must provide records, then provide the minimum subset needed to advantage your case and not subject you to criminal prosecution.  If you tell your opponent you have records, then you implicitly forfeit your 5^th Amendment right to not provide them, even if they would incriminate you!

We’d like to emphasize that the suggestions in this section is not intended to violate 26 U.S.C. §7206 item (4), which makes it a crime to conceal assets otherwise lawfully owed:

(4)  Removal or concealment with intent to defraud.

Removes, deposits, or conceals, or is concerned in removing,  depositing, or concealing, any goods or commodities for or in  respect whereof any tax is or shall be imposed, or any property  upon which levy is authorized by section 6331 with intent to  evade or defeat the assessment or collection of any tax imposed  by this title; or

….

shall be guilty of a felony and, upon conviction thereof, shall be fined not more than $100,000 ($500,000 in the case of a corporation), or imprisoned not more than 3 years, or both, together with the costs of prosecution.

If the other options presented elsewhere in this document are observed, then the reader will lawfully owe no income taxes and therefore, it will not be a criminal act to follow the suggestions in this section.  We know who the real criminal is here, don’t we?
