A practical, CPA-style checklist for staying compliant and keeping more of what you earn
“Current tax law” can feel like a moving target—especially when you’re juggling payroll, invoicing, and growth decisions. For Myrtle Beach business owners, the goal isn’t to memorize tax code. It’s to understand the few changes that meaningfully affect cash flow, estimated payments, payroll compliance, and year-end planning—then build a simple process around them.
1) Federal updates that impact planning (and timing)
Even if your business is based in South Carolina, federal rules tend to drive the biggest planning decisions—especially around withholding, deductions, and owner compensation. One of the most practical changes each year is IRS inflation adjustments (brackets, standard deduction thresholds, and other dollar limits). The IRS released the inflation adjustments for tax year 2026 (returns generally filed in 2027). (irs.gov)
2025 vs. 2026 standard deduction (useful for personal + pass-through planning)
| Filing status | Tax Year 2025 | Tax Year 2026 | Why it matters for business owners |
|---|---|---|---|
| Single / MFS | $15,750 | $16,100 | Affects your personal return, estimated taxes, and how much itemizing helps (if at all). |
| MFJ / Qualifying surviving spouse | $31,500 | $32,200 | Key for owners with pass-through income (S corp/partnership), especially with bracket management. |
| Head of household | $23,625 | $24,150 | Can materially change withholding and quarterly estimate targets for single-owner households. |

2) Payroll tax numbers you can’t afford to miss
If you have employees (or you’re an owner-employee), payroll errors create fast compounding problems—penalties, amended filings, and messy books. One number that changes regularly is the Social Security wage base. For 2026, the wage base is $184,500 (up from $176,100 in 2025). (payroll.org)
What Myrtle Beach employers should do
Confirm your payroll system applies Social Security tax only up to the wage base, and keeps Medicare calculations correct above that threshold. If you’re switching payroll providers or doing cleanup, reconcile W-2 totals to your quarterly payroll filings.
Owner compensation tie-in
For S corporations, “reasonable compensation” is a planning cornerstone. Wage base changes don’t replace the analysis—but they do affect total payroll tax cost and timing when you’re modeling the year.
Tip: If payroll feels like it “should be simple” but keeps eating your time, outsourcing can be a cost-control move—not just a convenience. See JTC CPAs’ Payroll Processing Services for a streamlined approach that ties payroll, compliance, and bookkeeping together.
3) Business mileage: a small line item that adds up
If you (or your team) drive for client meetings, bank runs, supply pickups, or job sites, mileage tracking is one of the cleanest ways to support deductions—when it’s documented properly. The IRS set the 2026 optional standard mileage rate for business at 72.5 cents per mile (effective January 1, 2026). (irs.gov)
Did you know?
- Mileage rates apply to electric and hybrid vehicles, too. (irs.gov)
- For a leased vehicle, if you choose the standard mileage method, you typically must use it for the entire lease period. (irs.gov)
- A “good enough” mileage log usually isn’t good enough in an audit—start/end points and business purpose matter.
A simple process that works
Pick one tracking method (app, spreadsheet, or calendar-based). Then set a recurring admin block—10 minutes every Friday—to confirm trips were captured while the details are still fresh. Your bookkeeper and CPA will thank you at year-end.
4) Step-by-step: a “current tax law” routine you can run all year
Step 1: Clean monthly books (so planning is real, not guesswork)
Tax planning works best when your financials are current. If transactions are unreconciled or categories are inconsistent, your “tax estimate” is just a hopeful number.

Step 2: Run quarterly tax projections (not just “quarterly payments”)
A quarterly projection looks at year-to-date profit, expected seasonality, payroll, big purchases, and owner draws—then adjusts estimated tax payments based on actual numbers. This is where “current tax law” becomes actionable.

Step 3: Make year-end decisions before December is over
Many tax-saving moves are timing moves—bonuses, retirement contributions, equipment purchases, receivables, and expense acceleration. Waiting until tax filing season can remove options.
If you need clean, decision-ready financial statements (especially for lending or investors), review Financial Compilations.
Step 4: Don’t ignore problems—resolve them strategically
If you’re behind on filings or have notices, the fastest path is usually a structured plan: verify transcripts, fix missing returns, confirm balances, and negotiate when appropriate.

5) Local angle: Myrtle Beach seasonality and South Carolina considerations
Many Myrtle Beach businesses live and die by seasonal cash flow—hospitality, trades, home services, real estate support, and professional services that spike during tourist months. “Current tax law” matters most when it intersects with timing: revenue surges can push you into higher effective tax exposure, strain payroll, and create estimated-tax surprises if you aren’t projecting quarterly.
What to do before your busy season ramps up
- Lock your bookkeeping cadence (weekly categorization + monthly reconciliation).
- Stress-test payroll for temporary hires and overtime workflows (approvals, documentation, and job costing).
- Build a “tax reserve” account and auto-transfer a percentage of each deposit.
- Track mileage and mixed-use expenses consistently—especially if you’re meeting clients across the Grand Strand.

FAQ: Current tax law for small businesses
Does “current tax law” change what I should pay quarterly?
Often, yes. Even when rates don’t change, inflation adjustments and your own profit fluctuations can shift your estimated tax needs. A quarterly projection (based on real books) is the most reliable way to avoid underpayment surprises.
What’s the difference between tax year 2025 and tax year 2026 updates?
Tax year 2025 items apply to returns typically filed in early 2026, while tax year 2026 items apply to returns typically filed in early 2027. The IRS provides annual inflation adjustments, including standard deduction updates. (irs.gov)
How should I document mileage deductions?
Keep a contemporaneous log that shows date, start/end, miles, and business purpose. For 2026, the IRS business standard mileage rate is 72.5 cents per mile. (irs.gov)
What payroll number should I update for 2026?
One key update is the Social Security wage base: $184,500 for 2026. This affects Social Security withholding and employer matching up to that wage limit. (payroll.org)
If I’m behind on taxes, should I wait until things “slow down”?
Delays tend to increase penalties and narrow your options. A structured resolution plan typically starts with clarifying what’s missing, fixing filings in the right order, and communicating proactively with tax authorities.
