How Long to Keep Business Financial Records
The IRS has specific retention requirements for business records. Keep these as a minimum:
Record Type
Keep For
Why
Tax returns
Indefinitely
No statute of limitations if fraud suspected
Supporting documents (receipts, invoices)
7 years
IRS can audit 6 years back if >25% income underreported
Employment tax records
4 years after tax due/paid
Payroll audit window
Business asset records (depreciation)
Life of asset + 7 years
Needed to calculate gain/loss on sale
Contracts and legal documents
Indefinitely
Disputes can arise years later
Bank statements
7 years
Tie to tax returns
Accounts receivable/payable ledgers
7 years
Support income and deductions
The practical rule: When in doubt, keep it for 7 years. Digital storage is cheap — there’s no good reason to delete financial records that might matter in an audit.
Double-Entry Bookkeeping: The Foundation Explained
Every financial transaction affects at least two accounts — this is the core principle of double-entry bookkeeping, used by every business from sole proprietors to Fortune 500 companies.
The rule: Debits = Credits. Every entry has an equal and opposite entry.
Transaction
Debit (increases)
Credit (decreases)
Client pays $1,000 invoice
Cash +$1,000
Accounts Receivable -$1,000
Buy $500 of supplies on credit
Office Supplies +$500
Accounts Payable +$500
Pay $500 supplier invoice
Accounts Payable -$500
Cash -$500
Owner invests $5,000
Cash +$5,000
Owner’s Equity +$5,000
Most small business owners never learn double-entry explicitly — their accounting software handles it automatically. But understanding the concept explains why QuickBooks asks you to categorize every transaction: it’s building the two-sided ledger that makes your financial statements accurate.
Why it matters: If your books are balanced (debits = credits), your Balance Sheet balances. If they don’t, something is misclassified, which leads to inaccurate tax returns and financial statements that don’t reflect reality.
Common Bookkeeping Mistakes
Mistake
Why It’s a Problem
How to Avoid It
Mixing personal and business expenses
Tax nightmare, liability risk
Use separate accounts for everything
Not reconciling monthly
Errors compound; year-end is a mess
Set a monthly calendar reminder
Shoe-boxing receipts
Lose deductions, fail audits
Use an app (Dext, Expensify) to scan immediately
Wrong expense categories
Inflates/deflates line items, confuses CPA
Set up your chart of accounts once and stick to it
Forgetting estimated taxes
IRS penalties (underpayment penalty)
Set aside 25-30% of every payment received
Not backing up data
Software failure loses everything
Cloud-based software handles this; still export quarterly
