⚠️ 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

PathCostTime
File yourself with your state's Secretary of State$50–$500 (varies by state)1–4 weeks
Northwest Registered Agent$39 + state fee1–2 weeks
Stripe Atlas$5001 week
LegalZoom / ZenBusiness / etc.$79+ + state fee1–4 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.

BankWhy
MercuryBest UI, free wires, virtual cards, integrates with everything
RelayFree, multiple accounts within one bank login (great for "tax bucket", "operating", etc.)
BluevineEarns interest on idle cash
Local credit unionIf 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:

MetricWhat it tells you
MRR (monthly recurring revenue)The most important number. Aim to grow it 20%/month for the first year
Gross marginRevenue minus variable cost (hosting + tools + contractors). Should be 75%+
Net marginRevenue 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:

  1. Reconcile your bank account (15 min if up to date, longer if not)
  2. Run your MRR report — total active subscriptions × monthly fee
  3. Compare to last month — are you growing? Flat? Shrinking?
  4. Check your tax buffer — is 30% of last month's revenue in the tax savings?
  5. Note any churn — who left, why, what would have prevented it
  6. Decide one thing to do this month — get one specific number better

Spend 15 minutes here, gain 15 hours of peace of mind.
