7 campaign finance mistakes that sink local candidates
Most local candidates don't lose on policy — they lose on paperwork. Here are seven avoidable Texas campaign finance mistakes and exactly how to dodge each one.
Here's the uncomfortable truth about local races: the candidate with the best ideas doesn't always win, but the candidate with a compliance scandal almost always loses. Texas campaign finance rules aren't designed to trip you up, yet first-time candidates fall into the same handful of traps every cycle — and every one of them is avoidable. None of these mistakes require a lawyer to prevent; they require knowing they exist. This is the list of seven that sink local candidates most often, why each one is dangerous, and exactly how to stay clean.
Key takeaways
- The single most common mistake is raising or spending money before appointing a treasurer — it's a hard legal line.
- Mixing personal and campaign funds is the error that quietly creates the biggest mess.
- Missing the 8-day report is public, avoidable, and the gift every opponent hopes for.
- Accepting prohibited contributions (corporate, union, over-the-cash-limit) creates refunds and amended reports.
- Most of these are solved by logging every transaction in real time and confirming details with your filing authority.
1. Spending or raising money before appointing a treasurer
This is the cardinal sin. In Texas you cannot accept a contribution or make an expenditure until your Campaign Treasurer Appointment (CTA) is on file with your filing authority. Yet excited first-time candidates routinely buy a domain, order shirts, or deposit an early check before the paperwork exists — and now their very first campaign act is a violation.
Fix
File your CTA first, before any money moves — even if you appoint yourself as treasurer. It takes one form. Our campaign treasurer appointment guide walks through it step by step.
2. Mixing personal and campaign funds
Running every charge through your personal debit card because it's convenient is the mistake that snowballs. Suddenly you can't tell which Amazon order was signs and which was groceries, your reports become guesswork, and reimbursements get murky. Texas has specific rules for spending from personal funds and seeking reimbursement, and a tangled account makes them nearly impossible to follow.
Fix
Open a dedicated campaign bank account the moment your treasurer is appointed, and run every contribution and expenditure through it. If you do spend personal funds intending reimbursement, document it correctly on the appropriate schedule of your Form C/OH.
3. Missing the 8-day pre-election report
Of all the deadlines, the 8-day pre-election report is the one candidates miss — and it's the worst one to miss, because it lands right when voters and opponents are paying maximum attention. A late filing is public record. In a small local race, that's a ready-made attack on your judgment.
Fix
Calendar the 30-day and 8-day deadlines with a one-week reminder the day you launch. See the full schedule mapped to this cycle in our Texas campaign finance deadlines for 2027.
4. Accepting prohibited or over-limit contributions
A supporter who owns a business offers a check from the company account. Another hands you $300 in cash. Both are problems: corporations and unions generally can't contribute to candidates in Texas, and cash is capped at a small amount per contributor per period (a figure commonly cited around $100 — verify the current limit). Accepting either means tracking down a refund and amending a report.
Fix
Refuse corporate and union money, keep cash under the limit (or just take checks and cards), and learn the source rules cold. Our Texas contribution limits and rules guide covers exactly who can give and how.
5. Forgetting in-kind contributions
A volunteer buys $400 of yard signs. A designer donates the logo. Because no money hit your bank account, candidates forget these are in-kind contributions — and skip reporting them. They're still real contributions, they must be reported at fair market value, and they're subject to the same source prohibitions (so an in-kind gift from a company is just as prohibited as a corporate check).
Fix
Ask every supporter who buys something *for* the campaign to tell you the value, and log it as in-kind the same day. Track these in real time — they're the contributions reconstruction always misses.
6. Vague or missing expenditure descriptions
Listing every expense as 'campaign expense' or 'advertising' is a red flag to reviewers and looks evasive to the public. Texas reports expect a specific purpose for itemized expenditures — what it was for, not just that it happened. Sloppy descriptions invite questions you don't want and can force amendments.
Fix
Describe each expenditure plainly: 'printing — 5,000 door hangers,' 'P2P texting platform,' 'venue rental — kickoff.' Specific is safe. If you run direct mail or texting, note the medium and purpose.
7. Filing with the wrong authority
The Texas Ethics Commission gets a lot of attention, so candidates assume that's where everything goes. For most local races it isn't: you typically file with your local filing authority — the city secretary for a city or mayoral race, the school district for an ISD trustee race. File the right form with the wrong office and you can be technically late even though you 'filed on time.'
Fix
Confirm your filing authority before your first report — call the office and ask exactly what they want and in what format. Our TEC filing guide explains how the state and local layers fit together.
Mandate prevents all seven before they happen.
Mandate's finance and compliance module enforces treasurer-first, separates campaign funds, flags prohibited and in-kind contributions, and counts down to every deadline — all beside your voter data, field app, and texting in one login. Nonpartisan, all-in-one, and built so a first-timer files like a pro.
The bottom line
Every mistake on this list is avoidable with the same three habits: appoint your treasurer first, run a separate campaign account, and log every transaction the day it happens. Do that, and compliance stops being a threat and becomes a non-event — leaving you free to spend your energy on voters.

Frequently asked questions
What is the most common campaign finance mistake in Texas?
Raising or spending money before appointing a campaign treasurer. In Texas you can't accept a contribution or make an expenditure until your Campaign Treasurer Appointment is on file — yet first-time candidates often spend on a website or merchandise before filing it.
Can I use my personal bank account for my campaign?
It's strongly discouraged. Mixing personal and campaign funds makes your reports unreliable and reimbursements murky. Open a dedicated campaign bank account when your treasurer is appointed and run every contribution and expenditure through it.
What happens if I miss the 8-day report?
A late report can carry escalating fines and becomes public record an opponent can use against you. The 8-day pre-election report is the most-watched filing of the cycle, so calendar both the 30-day and 8-day deadlines with reminders the day you launch.
Do I have to report donated goods or services?
Yes. In-kind contributions — like a supporter buying yard signs or a designer donating a logo — must be reported at fair market value, even though no cash entered your account, and they're subject to the same corporate and union source prohibitions.
Where do local Texas candidates file their reports?
Usually with their local filing authority — the city secretary for a city or mayoral race, or the school district for an ISD trustee race — not directly with the Texas Ethics Commission. Confirm your authority and its preferred format before your first report.
