I had a business for two years, did my own books, filed my own taxes, etc. I was based in the US and if I was in your position I would consider the following:
1. Take
@LetsCleanItTogether advice to convert to cold storage - protect the dinars.
2. If you're in the US, look at your state exceptions for taxable business activities, for example, in some states income from services is not taxed at the state level. Record your books income to match those tax exempt categories to reduce your state tax burden on paper.
3. If you have any equipment or other assets formally on your books be sure to depreciate/amortize them, it's fully deductible and not hard to make a depreciation/amortization schedule for audit purposes.
4. Avoid making claims to easy audit triggers, i.e. home office expense, just to reduce your tax burden.
5. Again just unique to the US, but as the current administration looks to cut back on the IRS (personnel and budget) the better a spot you will be in to fly under the radar - nothing tangible here just keep an eye on the news.
6. It's easier for an audit to hide stuff on the balance sheet than the P&L.
