Finance, Taxes & Business Setup
⚠️ This is general guidance, not legal or tax advice. Talk to a CPA in your state before making structural decisions.
Should you form an LLC?
Short answer: Yes, eventually. You can start as a sole proprietor for the first 60–90 days while you validate, but flip to an LLC before signing your second client.
Why an LLC
- Liability separation: if a client sues you (rare but possible), they sue the LLC, not your personal assets
- Professional perception: "Pinecone Web LLC" reads more credible than "John Smith d/b/a Pinecone Web"
- Banking: lets you open a business bank account (which you should regardless)
- Tax flexibility: can later elect S-corp taxation when you're profitable enough (typically $50K+ net)
Why not a corporation
For a solo / early-stage agency, an LLC gives you everything a corp gives you with way less paperwork. Skip the C-Corp / S-Corp formation until you have a CPA telling you the math works.
How to form one
| Path | Cost | Time |
|---|---|---|
| File yourself with your state's Secretary of State | $50–$500 (varies by state) | 1–4 weeks |
| Northwest Registered Agent | $39 + state fee | 1–2 weeks |
| Stripe Atlas | $500 | 1 week |
| LegalZoom / ZenBusiness / etc. | $79+ + state fee | 1–4 weeks |
Recommendation: Northwest Registered Agent. Cheap, no upsell pressure, you're done in a week.
After formation
- Get an EIN from the IRS (free, takes 10 minutes online)
- Open a business bank account (Mercury, Relay, or Bluevine — all free, online)
- Get business insurance (covered below)
- File a beneficial ownership report (BOI) within 90 days of formation — federal requirement as of 2024
Choose your state
- Default: form in your home state. Simplest, cheapest long-term, no extra registration.
- Don't form in Delaware/Wyoming "for tax reasons" unless your CPA specifically tells you to. You'll just end up registering in your home state anyway as a "foreign LLC" and paying double.
- Exception: if you're not a US resident, Delaware or Wyoming makes more sense.
Business banking
Don't mix personal and business money. It's the #1 way solo operators get into IRS trouble.
Recommended (all online, free, take 10 minutes to open)
| Bank | Why |
|---|---|
| Mercury | Best UI, free wires, virtual cards, integrates with everything |
| Relay | Free, multiple accounts within one bank login (great for "tax bucket", "operating", etc.) |
| Bluevine | Earns interest on idle cash |
| Local credit union | If you ever want a real loan, having a relationship matters |
What to set up
- One business checking account
- One business savings (sweep tax money here every month)
- One credit card in the LLC name (for points + accounting separation)
The "envelope" method (do this from day 1)
Every dollar that comes in, split it the moment it lands:
- 30% → tax savings account (set aside, never touch)
- 5% → operating buffer (cushion for slow months)
- 65% → operating account (your spending money)
If you do this religiously, you'll never have a tax surprise. Most solo operators get burned because they spend the gross and then can't pay quarterly taxes.
Taxes (US-focused)
What you'll owe (rough framework)
As a single-member LLC (default tax treatment), you pay tax on profits as personal income:
- Federal income tax: 10–37% depending on income bracket
- Self-employment tax: 15.3% (Social Security + Medicare) on the first ~$170K, 2.9% above
- State income tax: 0–13% depending on state
- Local tax: varies (some cities)
Combined typical effective rate: 25–40% of net profit. The "save 30%" envelope rule above is your safety margin.
Quarterly estimated payments
You owe taxes four times a year, not annually. Due dates:
- April 15
- June 15
- September 15
- January 15 (for the prior year)
Pay through IRS Direct Pay (free) or your accountant's portal. Underpayment penalties are real — usually a few hundred bucks if you skip a quarter, but they add up.
Deductions (the most common ones for an agency)
Things you can write off:
- Software subscriptions (your stack from doc 14)
- Domain registrations (yours and clients you pass-through)
- Hardware (laptop, monitor, headphones)
- Home office (% of rent/utilities for a dedicated workspace)
- Business meals (50% deductible)
- Travel for business (100% — flights, hotels, mileage)
- Professional services (CPA, lawyer, virtual assistant)
- Education (courses, books, conferences related to your work)
- Marketing (your domain, hosting, ads, business cards)
- Phone (% used for business)
What you cannot deduct:
- Your salary (you're not an employee of an LLC)
- Personal expenses with a business excuse (the "business meeting" at the steakhouse with your spouse)
- Time you donated to a non-profit (deduct expenses incurred, not your hourly rate)
S-Corp election (when to consider)
At ~$50K net profit, your CPA might suggest electing S-Corp tax treatment for your LLC. The trade-off:
- ✅ Save on self-employment tax on profits above your "reasonable salary"
- ❌ More paperwork (payroll, separate tax return)
- ❌ Need to actually run payroll (tools like Gusto: $40/mo + $6/employee)
Don't do it before $50K net. The complexity exceeds the savings below that threshold.
Business insurance
You probably need:
General Liability ($300–$800/yr)
Protects against bodily injury or property damage claims. Required if you ever set foot on a client's premises, attend events, or rent office space.
Professional Liability / E&O ($400–$1,200/yr)
Protects against claims that your work caused a client financial loss. Critical for agencies — if a client sues because their site went down during their busiest season, this is what saves you.
Cyber Liability ($500–$2,000/yr)
Protects against breaches, data loss, ransomware. Critical if you store any client data.
Where to get it
- Hiscox, Next, Coterie, Founder Shield — all online, get quotes in 10 minutes
- Local independent agent — slightly more expensive but they handle claims for you
Bundle for ~$1,000–$2,500/year total. Don't skip this — it's the cheapest sleep insurance you can buy.
Bookkeeping (the boring part that matters most)
Phase 1: 0–10 clients
Tool: Spreadsheet + business bank account. Cadence: Reconcile weekly. Categorize every transaction. What to track:
- Date
- Amount
- Category (revenue / software / hosting / pass-through / hardware / etc.)
- Client (if applicable)
- Notes
Phase 2: 10–30 clients
Tool: Wave (free) or Xero ($15/mo). Cadence: Reconcile weekly, categorize daily. Add:
- Linked bank feeds (auto-import transactions)
- Categorize once, train rules
- Generate P&L monthly (5 minutes)
- 1099 tracking for any contractors you hire
Phase 3: 30+ clients
Tool: Xero or QuickBooks Online + a part-time bookkeeper ($150–$400/mo). Cadence: You stop touching it. Bookkeeper reconciles, you review monthly.
Year-end
- Run a P&L for the full year
- Send to your CPA (or to TurboTax / FreeTaxUSA if you DIY for year 1)
- File 1099-NECs for any US contractors you paid >$600 to
- Pay your last quarterly estimate
When to hire a CPA
Hire one before your first tax filing season. Even if you DIY year 1, having someone review the return saves more than they cost.
What a good CPA does for an agency
- Files your taxes correctly (and identifies missed deductions)
- Advises on S-Corp election timing
- Helps with quarterly estimates
- Answers "can I deduct this?" questions throughout the year
- Reps you if the IRS comes knocking
What it costs
- Tax filing for an LLC: $400–$1,500/year depending on complexity
- Quarterly check-ins: $150–$300/quarter (worth it once you're at $100K+ revenue)
- Bookkeeping if they handle it: $200–$500/mo
How to find one
- Ask other small business owners in your area
- Search "small business CPA [your city]" — local is better than national
- Look for one who specializes in service businesses or agencies
Avoid: Tax-prep chains like H&R Block. Fine for personal taxes, not great for a business.
Financial milestones to track
Set quarterly goals on these numbers:
| Metric | What it tells you |
|---|---|
| MRR (monthly recurring revenue) | The most important number. Aim to grow it 20%/month for the first year |
| Gross margin | Revenue minus variable cost (hosting + tools + contractors). Should be 75%+ |
| Net margin | Revenue minus all costs (variable + fixed + your "salary"). Should hit 25%+ by year 2 |
| Churn rate | % of clients who cancel each month. Industry healthy: <5%/month |
| CAC (customer acquisition cost) | Time spent + money spent ÷ new clients. Aim for <2 months of subscription value |
| LTV (lifetime value) | Average client tenure × monthly revenue. Aim for LTV:CAC ratio of 5:1+ |
Pricing yourself (the salary question)
When the LLC starts making real money, you have to decide: how much to pay yourself vs. reinvest?
Year 1 reality
You'll make less than you would at a salaried job. Plan for this. Have ~6 months of personal expenses saved before quitting your day job.
Year 2 target
- Pay yourself ~50% of net profit
- Reinvest 30% in growth (better tools, contractor help, marketing)
- Save 20% in business buffer (12-month runway target)
Year 3+
- If MRR is stable and growing, pay yourself a real salary (S-Corp election helps here)
- Decide: keep growing as a solo operator, hire your first FTE, or sell the business
- Each path has different financial implications — talk to your CPA
Red flags & common mistakes
Avoid these landmines:
- ❌ Spending all the gross. Always set aside the tax %.
- ❌ Mixing personal and business. Separate accounts, no exceptions.
- ❌ Skipping quarterly taxes. The IRS finds you eventually.
- ❌ Underpricing to "get the deal." Discounts compound — you'll work twice as hard for half the money.
- ❌ Failing to invoice on time. Stripe automation solves this — set it up day 1.
- ❌ Not tracking pass-through costs. Domain renewals, photography, ad spend — log them as both income (paid by client) and expense (paid by you) so they net to zero.
- ❌ Missing the EIN/banking step. This unblocks everything else; do it the day your LLC is approved.
A simple monthly financial review (15 minutes)
Once a month, do this:
- Reconcile your bank account (15 min if up to date, longer if not)
- Run your MRR report — total active subscriptions × monthly fee
- Compare to last month — are you growing? Flat? Shrinking?
- Check your tax buffer — is 30% of last month's revenue in the tax savings?
- Note any churn — who left, why, what would have prevented it
- Decide one thing to do this month — get one specific number better
