Bookkeeping for
Consultants

Bookkeeping built for independent consultants and professional services

Independent consultants operate in a gray zone that most bookkeepers handle poorly. Your revenue is lumpy. Your expenses are mixed personal and business (one laptop for the client project and the evening Netflix session). Your clients send you 1099-NECs that rarely match the revenue on your books because of year-end cutoffs. Your home office is your largest deductible expense but it is also the one the IRS flags most often. And your quarterly estimated taxes are either paid too high, leaving cash trapped with the Treasury, or too low, generating underpayment penalties. A consultant-focused bookkeeper fixes all five of these at once.

Our consultant bookkeeping practice handles the specific issues professional services businesses face: 1099 reconciliation (1099s you receive from clients against revenue on your books, 1099s you send to subcontractors against expenses on your books); quarterly estimated tax projections that use actual year-to-date profit rather than last year's number, so you pay what you actually owe; home-office deduction calculation using the regular method (square footage plus a share of utilities, insurance, depreciation, and internet) when it produces a bigger deduction than the $1,500 simplified method; retainer and deferred revenue tracking so a client deposit on December 28 does not become December revenue when the work gets delivered in February; and project-level profitability so you know which engagements are actually making you money after unbilled time.

The S-corp election is the single biggest tax play for consultants in the DMV. Once your net profit crosses about $80K, you are usually paying self-employment tax on income that could legally be a distribution instead. A well-executed S-corp election with a defensible reasonable-compensation analysis can save a $150K consultant roughly $8K per year, and a $250K consultant $15K+ per year, net of payroll costs. But the election only works if your books are clean enough to support the salary-versus-distribution split. We build the foundation. If the numbers support an election, we handle the Form 2553, the entity setup, the Gusto or QuickBooks payroll onboarding, and the ongoing bookkeeping cadence.

Industry-specific FAQ

When should I switch from a sole proprietorship to an S-corp as a consultant?

The rough threshold is around $80,000–$100,000 in net profit. Below that, the administrative cost of running an S-corp (separate tax return, monthly payroll, reasonable-compensation documentation, state franchise taxes in some jurisdictions) usually exceeds the self-employment tax savings. Above that, every dollar you can defensibly treat as distribution instead of salary saves 15.3% in self-employment tax up to the Social Security wage base and 2.9% in Medicare tax above it. We run the projection against your actual bookkeeping data, document the reasonable-compensation analysis, and handle the Form 2553 election with the IRS.

How do I handle a retainer paid in December for work I will deliver in January?

You defer it. A retainer or deposit paid before the work is performed is a liability on your balance sheet (deferred revenue or customer deposit), not revenue on your P&L. The moment you deliver the engagement — or hit the contractual milestones — the liability moves to revenue. Recognizing it early inflates your tax bill in the current year and understates income in the year you actually earn it. We set up a deferred revenue account and train you on when to release balances. This also keeps your books aligned with how your client booked the expense on their side, which reduces 1099 reconciliation headaches at year-end.

What home-office expenses can I actually deduct as a DMV consultant?

If you use a room exclusively and regularly for your consulting work, you can deduct a proportional share of mortgage interest or rent, utilities (electric, gas, water, internet), homeowners or renters insurance, depreciation (for owners), and direct costs for that room. The calculation divides your office square footage by your total home square footage. The IRS simplified method gives a flat $5 per square foot up to $1,500, which is usually less than the regular method for DMV housing costs where rent and utilities are high. We calculate both approaches and use whichever gives you the bigger deduction, and we keep the substantiation (utility bills, square footage diagram) in case of audit.
