TL;DR for Busy Owners
Yes, there’s time to lower your bill. Prepay essentials you’ll truly use, elect the de minimis safe harbor, analyze Section 179 vs. bonus depreciation (don’t guess), fix stock-basis before you file, tune owner payroll and accountable plan reimbursements, bunch charitable gifts, max the HSA, top off retirement, true-up estimated taxes to safe harbor, clean books for QBI and 1099s, and review inventory for write-downs.
1) Prepay Essential Expenses You Already Need
What it is: If you use the cash method, you can pay in late December for items you would naturally pay in January or February: software renewals, professional fees, insurance, and supplies. The one-year rule is key for certain prepayments.
Why it lowers tax without choking cash: You’re not inventing spend. You are changing timing.
Aha moment: One check in December can secure twelve months of a must-have tool and drop the deduction into this year.
Numeric example: Prepay a $4,800 annual platform on December 29. With a 32% marginal rate, you reduce current-year tax by roughly $1,536.
How to execute: List recurring services you’re keeping. Confirm eligibility with your tax preparer near you. Pay the ones with clear ROI and stable vendor relationships.
2) Elect the De Minimis Safe Harbor for Small-Dollar Items
What it is: An annual election that lets you expense low-cost tangible items (monitors, peripherals, modest tools) instead of capitalizing them.
Why it’s cash-smart: You probably bought some of this already. This is paperwork leverage, not extra spending.
Aha moment: A written capitalization policy with a clear threshold turns dozens of $200–$500 purchases into current deductions.
How to execute: Draft a one-page policy. Apply it consistently. Attach invoices in your accounting system.
3) Section 179 vs. Bonus Depreciation: Analyze, Don’t Guess
What it is: Two expensing levers for qualifying equipment and certain software. You can blend by asset class.
Why it protects future years: The game isn’t “maximum today.” It’s “maximum where it matters.”
Aha moment: Split the purchase by asset class and timing. Accelerate what helps now, keep the rest to cushion next year’s spike.
Numeric sketch: Buy $120,000 of machinery. Elect 179 on $40,000 and depreciate the remaining $80,000 over time.
How to execute: Ask an Austin tax accountant for a three-column comparison: 179-heavy, bonus-heavy, straight-line.
4) Stock-Basis Planning for S Corps and Partnerships
What it is: Owners need sufficient stock basis (S Corps) or outside basis (partnerships/LLCs) to deduct losses.
Why it matters: Get basis right and paper losses can become real deductions.
Aha moment: A properly documented owner loan can create basis to unlock a deduction.
How to execute: Pull owner basis schedules now. Reconcile contributions, loans, distributions. Document real notes if adding debt basis.
5) Tune Owner Payroll and Health Insurance (S Corps)
What it is: Confirm reasonable compensation, align W-2 wages, and include shareholder health insurance on the W-2 when required.
Why it helps: Reasonable comp protects your return. W-2 wage levels can influence QBI.
Aha moment: A targeted year-end bonus can calibrate wages, unlock retirement deferrals, and tighten QBI positioning at once.
How to execute: Benchmark reasonable comp. Coordinate with payroll before the final run.
6) Sweep Accountable Plan Reimbursements You Forgot
What it is: Reimburse legitimate business expenses paid personally under a documented accountable plan.
Why it helps: Moves real costs onto the business for a deduction, reimbursements stay non-taxable if rules met.
Aha moment: A one-page accountable plan plus a year-end sweep often saves more than a last-minute gadget purchase.
How to execute: Adopt the plan. Gather receipts. Submit a December sweep with categories and dates.
7) Bunch Charitable Gifts with a Donor-Advised Fund
What it is: Bundle multiple years of giving into one tax year, often through a donor-advised fund.
Why it works: Same generosity, better timing. If you’re near the standard deduction, bunching can push you into itemizing.
How to execute: Contribute cash or appreciated securities before December 31. Grants can go out later.
8) Max the HSA (and Coordinate Family Coverage)
What it is: Contribute to a Health Savings Account if you have a qualifying high-deductible health plan.
Why it helps: Triple tax advantage—deductible contributions, tax-free growth, tax-free medical withdrawals.
How to execute: Confirm eligibility and contribution limits. Fund before the tax-filing deadline (usually April).
9) Top Off Retirement (and Coordinate Payroll)
What it is: Maximize contributions to Solo 401(k), SEP-IRA, SIMPLE IRA, or defined-benefit plans before deadlines.
Why it helps: Pre-tax contributions reduce current tax; Roth builds future tax-free pools.
Aha moment: Coordinate owner and spouse payroll to hit deferral limits. Tie year-end bonuses to retirement deferrals.
How to execute: Ask a certified CPA near you for a three-year contribution schedule. Confirm deadlines.
10) True-Up Estimated Taxes to Safe Harbor
What it is: Meet safe-harbor thresholds to avoid underpayment penalties using prior-year percentages or current-year projections.
Why it helps cash: You avoid penalties and interest that add no value.
Aha moment: You can raise W-2 withholding on a final payroll rather than writing a separate estimate.
Numeric example: Short by $12,000. Increase year-end withholding across two payrolls to meet safe harbor.
How to execute: Pull YTD P&L, payroll, gains. Model both safe-harbor paths with a tax accountant near you.
11) Clean Books for QBI, 1099s, and Inventory
What it is: QBI depends on accurate qualified income and wage ratios. 1099s rely on clean vendor data. Inventory may deserve write-downs.
Why it saves real money: Fix misclassifications and your QBI deduction often grows without new spending.
Aha moment: Two focused hours of cleanup often outperform a rushed equipment buy.
How to execute: Reconcile bank/credit cards, tie fixed-asset schedules, verify owner wages, run vendor report, review inventory for obsolete items.
Year-End Forms and Self-Employed Reality: A Quick Deep Dive
W-9 and 1099-NEC: Collect W-9s before year-end and issue 1099-NEC where required.
1099-K: Reconcile platform statements monthly. Thresholds evolve.
Self-employment tax: Model it beside income tax. A quick projection can change timing decisions.
QuickBooks Self-Employed habits: Automate rules, split business/personal cleanly, keep vendor summary for missing W-9s.

Frequently Asked Questions
I’m late. What three moves should I do first?
Run a projection to spot your marginal bracket and safe-harbor gap. Adopt de minimis with a one-page policy. Sweep accountable plan reimbursements you forgot. Those three are quick and usually high-value.
How do I pick between Section 179 and bonus depreciation?
Match deductions to your profit arc. If this year is strong, accelerate more now. If next year looks bigger, keep depreciation for then. Ask your Austin, Texas CPA for a three-column comparison with cash impact by year.
What is stock-basis planning in plain English?
It’s the rule that says you need enough basis to deduct losses. Basis rises with real contributions and certain direct loans. If you lack basis, losses can be suspended. Structured correctly, a year-end owner note may unlock deductions.
Is donor-advised bunching only for big givers?
No. If bunching pushes you above the standard deduction in one year, even moderate givers can benefit, especially when contributing appreciated securities.
Which bookkeeping fixes most influence QBI?
Accurate owner wages, cleaned guaranteed payments, correct depreciation tied to fixed-asset schedules, timely closings, and precise revenue and expense classifications. Many owners discover that two hours of cleanup beats a last-minute purchase.
