Houston taxpreparer guide to IRS filing deadlines

What to take away

Why Houston preparers carry a federal-first workload

This taxpreparer guide starts with the operational distinction: Texas has no personal income tax, so Houston preparers generally do not file a Texas individual income tax return. Individual federal work centers on Form 1040, its schedules, and the information returns that feed it. Clients with income sourced to another state may still have a state filing.

That removes a whole reconciliation step. There is no state form to tie back to the federal return, no state refund to track, and no state e-file acknowledgment to wait on. Quality control is one return, checked once.

The freed hours go into business work. An entity return takes longer than an individual return, and Houston has no shortage of entities. Firms that once split staff across two filing systems now run a single federal pipeline.

It changes hiring too. A preparer who knows Texas taxes no income still needs federal depth: basis, depreciation, reasonable compensation, and the pass-through rules that decide most Houston business returns. For owners deciding where to put staff, this is one of the markets worth entering because the federal work is dense.

Federal-first is not simpler. It is one jurisdiction instead of two, and a client base that expects business tax knowledge, not just personal.

For partnership rules, use IRS Publication 541, Partnerships, alongside the current instructions for Form 1065. IRS Publication 509, Tax Calendars, is a named reference for federal due dates; preparers should also check the current instructions for each return form.

What replaces the state income tax return

No Texas personal income tax return means no state withholding on wages and no state income tax extension to file. What remains is a different set of taxes Houston clients still owe.

Texas franchise tax reports are administered by the Texas Comptroller of Public Accounts. For entities required to file, applicable reports include Form 05-158-A or Form 05-158-B and are generally due May 15; many entities also file a Public Information Report, Form 05-102. Sales tax applies to many goods and services, with the Texas Comptroller assigning monthly, quarterly or annual filing frequency; returns and payments are generally due on the 20th day of the month after the reporting period ends. Harris County property tax bills are generally due Jan. 31; appraisal protests go to the Harris Central Appraisal District (HCAD), generally by May 15 or 30 days after the appraisal notice is delivered, whichever is later.

A preparer does not need to be a franchise tax specialist to be useful. The job is to flag the obligation, keep the federal return consistent with what the entity reported to the state, and refer the rest. A client who hears nothing about franchise tax assumes nobody is watching.

Payroll is the other replacement. With no state withholding, federal withholding, Social Security and Medicare carry the whole load. Deposit schedules and quarterly returns matter more, because no second agency catches a missed payment.

For federal payroll obligations, use IRS Publication 15 (Circular E), Employer's Tax Guide. Publication 505, Tax Withholding and Estimated Tax, covers estimated tax basics; direct clients to the current publications and keep the filing work in house.

Energy clients and their entity return patterns

Houston energy work shows up in the return stack before it shows up in the invoice. One client group may hold an operating LLC, a partnership for the wells, an S corporation for services, and a holding entity above them.

That is several returns per client, each with its own due date and its own extension decision. The partnership return drives the Schedules K-1 that flow into the owners' individual returns, so a late partnership return delays everything above it.

Energy clients also file in more than one state. An owner living in Houston may have income sourced to Louisiana, Oklahoma, New Mexico or North Dakota. Texas does not tax that income. Those states do, on their own forms and their own deadlines.

Fixed assets and depletion make the numbers heavy. Cost segregation studies, intangible drilling costs and depletion schedules all need documentation, and a file opened in March will not close by the deadline. Open energy files in the fall and close the entity returns before the individual ones.

Entity setup belongs in intake. A new energy client often needs an employer identification number before anything can be filed; the client applies to the IRS using Form SS-4, Application for Employer Identification Number.

These are the return types Houston energy preparers see most.

Small business and self-employed clients in the Houston market

Small business clients are the steady volume, and they behave nothing like wage earners. They pay estimated tax, they keep their own books, and many arrive with a shoebox rather than a ledger.

The first job is the entity question. Sole proprietor, single-member LLC, partnership, S corporation and C corporation each produce a different federal return and a different deadline set. The wrong choice costs the client self-employment tax or filing fees.

The second job is documentation. Houston's small business mix runs from restaurants and contractors to medical practices and logistics brokers. Each carries deductions that need support: mileage logs, home office measurements, equipment purchases, and contractor payments reported on Form 1099-NEC.

Self-employed clients need quarterly attention, not just an annual return. A preparer who sees them only in April misses underpayment problems that were visible in June. Some firms sell a mid-year checkup as its own service, which fits the list of profitable tax preparation services that hold margin across the year.

Extension season is where these clients get hurt. An individual client requests a filing extension with Form 4868; a business generally uses Form 7004. An extension moves the filing date, not the payment date, so estimate and pay any tax due by the original deadline.

Scheduling around federal deadlines with no state anchor

For Texas individual income tax, Houston has no state due date to stagger the federal workload. Franchise, sales and property tax obligations still have their own state or local calendars, so practices track those separately instead of treating the federal calendar as the only calendar.

Calendar-year Form 1040 and Form 1120 returns are due April 15; Forms 1065 and 1120-S are due March 15. A weekend or federal holiday moves the deadline to the next business day; fiscal-year entities generally use the 15th day of the third month after year-end for Forms 1065 and 1120-S, and the fourth month for Form 1120. A timely Form 4868 generally extends an individual return to October 15; Form 7004 generally extends calendar-year Forms 1065 and 1120-S to September 15 and Form 1120 to October 15, but neither extension delays payment. Check IRS Publication 509, Tax Calendars, and the current form instructions for the filing year.

With no Texas individual income tax deadline, Houston firms build internal deadlines ahead of federal dates, giving business returns that produce Schedules K-1 room to clear first. The calendar below separates firm document dates from IRS filing deadlines.

A workable federal-first calendar:

A checklist keeps the calendar honest:

Staffing follows the same logic. One filing peak instead of two means Houston firms hire and train against the federal calendar, then use the summer for entity cleanups and bookkeeping catch-up. That rhythm runs better on a documented operations and workflow guide than on memory.

Client communication is the last piece. Clients who moved from a state with income tax may expect a Texas state income tax return or refund. Explain in writing that Texas taxes no personal income and that the federal return is the Texas resident's individual income-tax filing, while other state and Texas business or local tax obligations may still apply.

Firms that explain it well tend to win more tax preparation clients through referrals from people who finally understood their own return.

Common questions

Do Houston tax preparers file any state income tax return?

Not for Texas residents on Texas income. Texas taxes no personal income, so the individual filing is federal. Clients with income sourced to other states may still owe those states' returns, and the rules there are set by each state's tax authority.

When are business returns due with no state deadline?

For calendar-year returns, Forms 1065 and 1120-S are generally due March 15, and Form 1120 is generally due April 15. If a deadline falls on a weekend or federal holiday, it moves to the next business day. Form 7004 generally extends calendar-year Forms 1065 and 1120-S to September 15 and Form 1120 to October 15; payment remains due by the original deadline. Check IRS Publication 509 and the current form instructions for the filing year.

Do energy clients need more than one return?

Often yes. One client group may hold a partnership, an S corporation and a holding entity, each with its own federal return and its own extension decision. Multi-state sourcing adds returns in the states where the income arises.

What replaces the state return for a small business client?

Texas franchise tax reports, sales tax filings and property tax obligations have separate deadlines. Applicable franchise tax reports, such as Forms 05-158-A or 05-158-B, are generally due May 15; Texas sales tax returns and payments are generally due on the 20th day of the month after the assigned reporting period. Property tax bills are generally due Jan. 31, and appraisal protests in Harris County generally go to the Harris Central Appraisal District by May 15 or 30 days after the appraisal notice is delivered, whichever is later. The Texas Comptroller of Public Accounts administers franchise and sales taxes.

Can a client extend a federal return without paying?

No. Form 4868 extends the time to file an individual return, and Form 7004 generally extends the time to file a business return; neither extends the time to pay. A client who owes should pay by the original deadline to limit penalties and interest.
