Common Year-End Mistakes
Learn from others' mistakes:
Mistake #1: Not Planning
The problem: You don't review year-end opportunities, miss tax savings
The solution: Review in November, take action in December
Mistake #2: Buying Unnecessary Items
The problem: You buy equipment you don't need just to get deduction
The solution: Only buy what you need (deduction doesn't make it free)
Mistake #3: Not Contributing to Retirement
The problem: You could contribute $20,000 but don't, missing tax savings
The solution: Maximize retirement contributions (double benefit: tax savings + retirement savings)
Mistake #4: Not Organizing Records
The problem: You wait until tax time to organize, making it stressful
The solution: Organize throughout year, especially at year-end
Frequently Asked Questions
When Is the Deadline for Year-End Actions?
December 31: Cutoff for most strategies (purchases, expenses, etc.)
Some exceptions: Retirement contributions can be made until tax filing deadline (but better before year-end)
Can I Still Deduct Expenses Paid in January?
Depends on accounting method:
- Cash method: Deduct when paid (so January payment = next year deduction)
- Accrual method: Deduct when incurred (may be this year if incurred in December)
Most freelancers: Cash method, so must pay before December 31
How Much Should I Contribute to Retirement?
Maximum possible (within your means):
- SEP-IRA: 25% of net income, up to $69,000
- Solo 401(k): $23,000 employee + 25% employer, up to $69,000
Every dollar saves taxes: Maximize if possible
