Frequently Asked Questions
What business entity types does ASU prepare tax returns for?
ASU prepares tax returns for every common business entity type: sole proprietorships (Schedule C), single-member LLCs, multi-member LLCs (Form 1065), S-Corporations (Form 1120-S), C-Corporations (Form 1120), partnerships, and nonprofits (Form 990 series). We also prepare personal returns (Form 1040) for business owners and complex individual filers.
Does ASU handle Louisiana sales tax as well as income taxes?
Yes. ASU handles both. Income tax preparation (federal and state) and sales tax filing are separate services, but most ASU bookkeeping clients have both handled by the same team. Louisiana sales tax is filed monthly or quarterly for all applicable parishes — ASU covers all 64. See our Sales Tax Filing page for details.
What commonly triggers an IRS audit and how can I reduce my risk?
Common audit triggers include: income significantly above or below industry averages, unusually high deductions as a percentage of income, large cash transactions, inconsistencies between reported income and 1099s filed by payers, and home office deductions that seem disproportionate to business size. The best defense is clean, well-documented books — which is exactly what monthly bookkeeping provides.
What's the difference between tax avoidance and tax evasion?
Tax avoidance is legal — it means using legitimate deductions, credits, and strategies to reduce your tax liability. That's what a good tax preparer does for you. Tax evasion is illegal — it means deliberately misreporting income, hiding assets, or falsifying records to avoid paying taxes you legally owe. ASU only practices tax avoidance, and we refuse to prepare returns that misrepresent facts.
What are the most important business tax deadlines I need to know?
Key dates: January 31 — W-2s and 1099s to employees and contractors. March 15 — S-Corp and partnership returns (Form 1120-S, 1065). April 15 — Individual and C-Corp returns (Form 1040, 1120). Louisiana parish sales tax is due the 20th of the month following the reporting period. Quarterly estimated taxes are due April 15, June 15, September 15, and January 15. See our Louisiana Tax Deadlines page for the full calendar.
Can I deduct my home office on my business taxes?
Yes, if you use part of your home regularly and exclusively for business. The IRS allows two methods: the simplified method ($5/sq ft, up to 300 sq ft = max $1,500 deduction) and the regular method (actual expenses proportionate to home office percentage). The regular method is often larger but requires more documentation. Your home office must be your principal place of business or where you meet clients regularly.
What business expenses are generally deductible?
Common deductible business expenses include: advertising and marketing, bank fees, contract labor (with proper 1099 documentation), business insurance, business-use vehicle expenses, depreciation on business equipment, business meals (50%), professional subscriptions and dues, rent for office or retail space, wages and payroll taxes, and home office (if qualifying). ASU identifies every applicable deduction at tax prep time.
How long should I keep my business tax records?
The IRS generally has 3 years from the filing date to audit a return, so keeping records for at least 3 years is the minimum. If you underreported income by more than 25%, the IRS has 6 years. For employment tax records, keep for at least 4 years. Asset purchase records should be kept for as long as you own the asset plus 3 years. ASU recommends keeping all business tax records for 7 years minimum.
