Tax Strategy for consultants
A consultant's deduction profile is dominated by the home office, professional liability insurance, and continuing education, which is a required cost of maintaining a licence or certification. Professional liability insurance is frequently overlooked and is fully deductible as an ordinary and necessary business expense, as is the cost of the credentials clients increasingly require.
Consulting revenue often arrives in large retainers or milestone payments rather than monthly hours. If a client pays a quarterly retainer in advance, the income is taxable on receipt, which can push a single quarter's liability well above a straight-line division of the annual total.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
