Tax Return Preparation

Here’s something we tell every new client: the tax return is the last thing we do, not the first. That usually gets a raised eyebrow, because most people come to a CPA firm specifically to get their tax return done. We get it. But here’s the thing – your tax return is a report card. It reflects what already happened. The strategy, the planning, the entity decisions, the payroll calibration, the retirement contributions, the rental property structuring – all of that happens throughout the year. The return just keeps score.

That distinction matters because most firms treat tax preparation as a once-a-year transaction. You drop off documents in February, someone plugs numbers into software, and a return pops out in April. Maybe you owe, maybe you get a refund, and either way the experience leaves you wondering if anything could’ve been done differently. The answer is usually yes – but by the time you’re filing, it’s too late. The game is over. You’re just reading the box score.

At WCG, tax return preparation is the visible output of everything else we do. The entity you selected drives which return gets filed. The bookkeeping drives the numbers that go into it. The advisory and tax planning drives the strategies that show up on it. When all of those pieces are working together, the return isn’t a surprise – it’s a confirmation. And honestly? That’s how it should feel.

Who Is This Page For?

This page is for business owners, self-employed professionals, real estate investors, and high-income earners who want tax return preparation that actually connects to a broader strategy. Specifically:

  • You’re an S Corp owner and need Form 1120-S prepared by someone who also understands reasonable salary, distribution timing, and shareholder basis – not just the data entry
  • You own rental properties and want a preparer who knows cost segregation, passive activity rules, and 1031 exchanges – not someone Googling depreciation schedules in March
  • You file in multiple states and need someone who can navigate nexus, apportionment, and state-specific quirks without creating a compliance mess
  • You’re a high-income earner with W-2 income, K-1s, investments, and maybe a side business, and your return has gotten too complex for the local tax shop
  • You’ve been burned before – missed deductions, late filings, penalties, or a preparer who clearly didn’t understand your situation
  • You already work with WCG for advisory or planning and want your return prepared by the same team that built the strategy (spoiler: that’s exactly how we do it)
  • You’re looking for a second opinion on a return prepared elsewhere and want to know what was missed

If any of that resonates, you’re in the right place.

Our Philosophy on Tax Returns

We’ve been saying this for 20 years and we’ll keep saying it: a tax return is a report card, not a strategy. The strategy happens in January through December. The return just tells you how well the strategy was executed.

Think of it this way. If you wait until you’re sitting across from your tax preparer in March to ask “What can we do to lower my taxes?” – you’ve already lost. The decisions that move the needle happened months ago. Did you set up the right entity structure? Did you run payroll at the right salary level? Did you make retirement contributions before the deadline? Did you time that equipment purchase correctly? Did you elect into your state’s pass-through entity tax before year-end? Those are the questions that drive your tax outcome. The return just records the answers.

Having said that – we still take return preparation very seriously. Because even the best strategy falls apart if the return is sloppy. A missed K-1 entry, a wrong depreciation method, a state filing that gets overlooked – those things create real problems. Amended returns, penalties, interest, and the occasional unpleasant letter from the IRS (or worse, your state department of revenue). So yes, the return is the last thing we do. But we do it right.

The WCG Difference

Here’s what makes us different from most tax prep firms, and it’s not software or technology or a fancy portal (although we have those too). It’s this: every return at WCG is prepared by someone who also does tax planning.

Read that again.

There is no disconnect between the strategy team and the prep team. They’re the same people. The advisor who helped you decide between an LLC and an S Corp in June is the same person preparing your Form 1120-S in February. The person who ran your S Corp analysis and recommended a reasonable salary of $65,000 is the same person making sure that salary flows correctly through the return. The person who helped you navigate a 1031 exchange is the same person reporting it on your 1040.

Why does this matter? Because at most firms, tax planning and tax preparation are different departments. The planner says “do X,” and then hands the file to a preparer who may or may not understand why X was done. Things get lost. Context disappears. And the return ends up being technically correct but strategically disconnected – which means the next year’s planning starts from a position of confusion instead of clarity.

At WCG, your return is the natural conclusion of a year-long relationship. No handoffs. No lost context. No “wait, why did they do that?” moments. Just a clean, accurate return that reflects the strategy we built together.

Business Tax Returns

We prepare business returns across every major entity type. Here we go-

S Corporation Returns (Form 1120-S)

This is the bread and butter for most of our business clients. If you elected S Corp status (and if you’re earning above $60,000-$80,000 in net income, you probably should have), your business files Form 1120-S and issues K-1s to shareholders. Getting this right means more than plugging in revenue and expenses. It means properly tracking shareholder basis, handling reasonable compensation, managing distributions, and making sure the return aligns with the payroll that was run throughout the year. We see botched 1120-S returns all the time from other firms. Basis issues, loan documentation gaps, distributions that exceed basis – yuck.

Partnership Returns (Form 1065)

Multi-member LLCs, general partnerships, limited partnerships – they all file Form 1065. Partnership returns are more complex than most people expect, especially when you get into special allocations, guaranteed payments, partner capital accounts, and the Section 199A deduction. If you’ve got a partnership with multiple owners doing different things, the return can get complicated quickly.

C Corporation Returns (Form 1120)

C Corps are less common among our client base, but when they show up, they tend to be complex – multiple shareholders, accumulated earnings considerations, reasonable compensation issues (from the other direction), and the ever-present question of double taxation. We also see C Corps in the context of holding companies and tiered structures.

Business Tax Prep Services

The key with all business returns is that the return quality is only as good as the bookkeeping that feeds it. Garbage in, garbage out. Period. Full stop. That’s why we push so hard on clean books throughout the year – not because we love debits and credits (well, some of us do), but because a clean general ledger makes for a clean return, which makes for a defensible return if the IRS ever comes knocking.

Individual Tax Returns

Your Form 1040 is where everything comes together. All the K-1s from your business returns, your W-2 income, your investment income, your rental property activity, your retirement contributions, your itemized deductions – it all lands on the 1040. For our clients, this is rarely a simple return.

High-Income and Complex Returns

If you’ve got adjusted gross income above $250,000, multiple income sources, investment portfolios, stock options, or deferred compensation – your return needs someone who understands how all these pieces interact. Alternative Minimum Tax considerations, Net Investment Income Tax (the 3.8% surtax that sneaks up on people), phase-outs on deductions and credits, estimated tax payment optimization – these aren’t things you want handled by someone who primarily does straightforward W-2 returns.

Standard Individual Returns

Not every return is wildly complex, and that’s fine. We prepare individual returns for clients across the income spectrum. But even a “standard” return benefits from having a preparer who knows your full picture. Did you change jobs? Move states? Get married? Start a side business? Sell investments? Each of those events has tax implications, and catching them proactively is what separates good preparation from data entry.

State & Local Tax Expertise

Sidebar: state taxes are where things get messy. Federal tax law is complicated enough, but at least it’s one set of rules. States? Every state has its own income tax rates (or no income tax at all), its own filing requirements, its own nexus rules, and its own deadlines. And if you’re operating in multiple states or you’ve moved during the year, it gets exponentially more fun (and by fun, we mean expensive if you get it wrong).

Multi-State Filing

If your business has employees, customers, or property in more than one state, you likely have filing obligations in each of those states. Nexus – the legal threshold for when a state can tax you – used to be straightforward. Physical presence meant nexus. Now, thanks to economic nexus rules and the post-Wayfair landscape, you can trigger filing requirements based on revenue alone. We help clients sort through which states require filings, how to apportion income, and how to avoid penalties for non-filing in states they didn’t even know were on the radar.

Pass-Through Entity Tax (PTET) Elections

This is one of the most elegant workarounds in recent tax history. After the Tax Cuts and Jobs Act capped the state and local tax (SALT) deduction at $10,000 for individuals, states started creating pass-through entity tax elections that let S Corps and partnerships pay state tax at the entity level – effectively circumventing the cap. It’s legal, it’s IRS-approved, and it can save you thousands. But you have to elect in, and in most states, you have to do it before year-end. We make sure our clients don’t miss it.

Sales Tax Compliance

Sales tax is a different animal from income tax, but it’s increasingly landing on our clients’ desks – especially those selling products online or across state lines. We help with registration, filing, and making sure you’re collecting and remitting correctly. Because the penalties for getting sales tax wrong are not gentle.

Specialty Areas

Some returns require specialized knowledge that goes beyond general tax preparation. Real estate is the big one for us.

Rental Property Returns

Rental properties generate their own unique set of tax reporting challenges – depreciation schedules, passive activity rules, material participation tests, the Section 199A deduction for rental income, and the interplay between rental losses and your other income. If you’ve done a cost segregation study (and if you own investment property, you should at least evaluate one), the accelerated depreciation needs to flow correctly through the return. We prepare returns for landlords with one property and portfolios with fifty. The complexity scales, but the principles don’t change.

1031 Exchange Reporting

If you’ve done a like-kind exchange, the reporting requirements are specific and unforgiving. The exchange needs to be properly documented, the deferred gain needs to be tracked, and the replacement property’s basis needs to be correctly calculated. We’ve seen exchanges blow up on the return because the preparer didn’t understand the mechanics. That’s an expensive mistake.

Tax Return Review & Second Opinion

Maybe you already have a preparer. Maybe you’re not sure they’re catching everything. We offer tax return reviews where we go through your prior-year return and identify missed deductions, incorrect elections, and strategic opportunities. It’s not about throwing your current CPA under the bus – it’s about making sure nothing is being left on the table. Sometimes we find $500. Sometimes we find $15,000. Either way, you walk away knowing.

How Return Prep Connects to Everything Else

This is the part most firms miss – and it’s the part we’re most passionate about. Tax return preparation doesn’t exist in a vacuum. It’s the final output of a coordinated system. Here’s how it all connects:

Entity Selection → Return Type

The entity you chose determines which return gets filed. Sole proprietor? Schedule C on your 1040. Single-member LLC? Same thing (the LLC is disregarded for tax purposes). LLC with S Corp election? Form 1120-S plus your 1040. Partnership? Form 1065 plus K-1s to all partners. The entity decision is the first domino.

Bookkeeping → Return Accuracy

Your books are the raw data that feeds the return. If the books are clean, categorized correctly, and reconciled monthly, the return practically builds itself. If the books are a mess – miscategorized transactions, unreconciled accounts, personal expenses mixed in with business expenses – the return becomes a forensic accounting exercise. We spend more time fixing bad books in March than we’d like to admit.

Advisory → Return Strategy

The tax planning we do throughout the year is what shows up on the return as actual savings. Retirement contributions, equipment purchases under Section 179, salary adjustments, estimated tax payments, PTET elections, charitable giving strategies – none of these are “tax return” decisions. They’re planning decisions that manifest in the return. When you work with us year-round, the return is the confirmation, not the discovery.

Payroll → Employment Tax Compliance

If you’re running an S Corp, your payroll feeds directly into both your 1120-S and your 1040. W-2s, payroll tax returns (941s, state withholding), unemployment filings – all of these need to reconcile with the business return and your personal return. When payroll is handled internally, we control the data. When it’s handled elsewhere, we need to verify everything matches. Mismatches between payroll and the business return are one of the most common triggers for IRS notices.

Key Takeaways

  • The tax return is a report card, not a strategy. The planning happens throughout the year. The return just records the results. If the first time you think about tax savings is during filing season, you’ve already missed most of the opportunities.
  • Your preparer and your planner should be the same person. At WCG, the advisor who builds your tax strategy is the same person who prepares your return. No handoffs, no lost context, no disconnect between what was planned and what gets filed.
  • Business return quality depends on bookkeeping quality. A clean general ledger produces a clean, defensible return. Messy books produce returns that are expensive to prepare, prone to errors, and harder to defend if questioned.
  • State taxes are where most people get surprised. Multi-state filing obligations, PTET elections, and sales tax compliance are increasingly complex – and the penalties for getting them wrong are real. Don’t ignore state-level planning.
  • Rental property returns require specialized knowledge. Depreciation, passive activity rules, cost segregation, 1031 exchanges – these aren’t things a generalist preparer handles well. If you own investment real estate, work with a firm that does this every day.
  • A second opinion can pay for itself. If you’re not sure your current preparer is catching everything, a tax return review can identify missed deductions and incorrect elections. We find money for people all the time.
  • Year-round preparation beats seasonal scramble. When your tax prep is integrated with planning, bookkeeping, and advisory, filing season is a non-event – not a crisis. That’s the goal.

Frequently Asked Questions

Here are some quickie FAQs to learn more about WCG CPAs & Advisors, and how we handle tax return preparation-

What types of tax returns does WCG prepare?

We prepare S Corporation returns (Form 1120-S), partnership returns (Form 1065), C Corporation returns (Form 1120), and individual returns (Form 1040). We also handle multi-state filings, rental property returns, 1031 exchange reporting, PTET elections, and sales tax compliance. If it hits a tax form, we probably prepare it.

How is WCG’s tax return preparation different from other firms?

The biggest difference is integration. At most firms, tax planning and tax preparation are separate departments – or separate firms entirely. At WCG, the person who prepares your return is the same person who does your tax planning. That means the strategies we recommend actually show up correctly on the return, and nothing gets lost in translation.

When should I start preparing for tax season?

Yesterday. Seriously though – the best time to start preparing for tax season is January 1 of the tax year, not January of the following year. That’s when entity elections, payroll calibration, retirement planning, and estimated tax decisions happen. If you’re a WCG client, we’re preparing for your return all year long. The actual filing in spring is just the final step.

Do I need to be local to Colorado Springs to work with WCG?

Not at all. We work with clients in all 50 states. Everything is handled digitally – document upload, review calls, e-signature, and electronic filing. We have clients from Maine to Hawaii and everywhere in between. The only thing you’ll miss is the Colorado sunshine.

What is a PTET election and does it apply to me?

PTET stands for Pass-Through Entity Tax. It’s a state-level election that allows S Corps and partnerships to pay state income tax at the entity level, effectively working around the $10,000 SALT deduction cap on your personal return. Most states now offer some version of this election. If you own a pass-through business and itemize your deductions, it almost certainly applies to you – and it needs to be elected before year-end in most states.

How does my entity type affect which tax return I file?

Your entity type is the first domino. Sole proprietors and single-member LLCs file Schedule C on their personal 1040. LLCs that elected S Corp status file Form 1120-S (the business return) plus the owner’s 1040 (the personal return). Partnerships and multi-member LLCs file Form 1065 with K-1s issued to each partner. C Corporations file Form 1120. The entity selection drives everything downstream.

What happens if my prior-year return has errors?

We can review prior-year returns and file amended returns if we identify errors, missed deductions, or incorrect elections. In many cases, you can go back three years to claim refunds. We’ve found everything from missed depreciation deductions to incorrectly reported 1031 exchanges. A tax return review is the first step.

Do you prepare returns for rental property owners?

Absolutely. Rental property returns are one of our core specialties. We handle depreciation schedules, passive activity loss calculations, cost segregation reporting, 1031 exchange documentation, and the Section 199A deduction for rental income. Whether you own one rental or fifty, we’ve seen your situation before.

What documents do I need to provide for my tax return?

It depends on the complexity of your return, but generally: W-2s, 1099s, K-1s from partnerships or S Corps, mortgage interest statements (1098), property tax records, retirement contribution records, health insurance documentation (1095 forms), and any other income or deduction documentation. For business returns, we need a clean general ledger, payroll reports, and supporting schedules. We send a detailed organizer each year so nothing gets missed.

How long does it take WCG to prepare my return?

Turnaround depends on complexity and time of year. For clients who provide complete documentation, most returns are completed within 2-4 weeks during peak season (February through April) and 1-2 weeks outside of peak season. Extensions are always available and often strategically advisable if we’re waiting on K-1s or other third-party documents. Filing an extension does not increase audit risk – that’s a myth we’re happy to bust.

Let’s Chat

If you need tax return preparation — whether that’s a single Schedule C or a multi-entity, multi-state filing that looks like a small country’s tax code — let’s talk it through. We typically start with a quick conversation to understand where you’re at and where you’re trying to go. No pressure. No sales pitch. Just a smart discussion so you can make a good decision.

The tax advisors, business consultants and rental property experts at WCG CPAs & Advisors are not salespeople; we are not putting lipstick on a pig expecting you to love it. Our job remains being professionally detached, giving you information and letting you decide within our ethical guidelines and your risk profiles.

We see far too many crazy schemes and half-baked ideas from attorneys and wealth managers. In some cases, they are good ideas. In most cases, all the entities, layering and mixed ownership is only the illusion of precision. As Chris Rock says, just because you can drive your car with your feet doesn’t make it a good idea. In other words, let’s not automatically convert “you can” into “you must.”

Let’s chat so you can be smart about it.

We typically schedule a 20-minute complimentary quick chat with one of our Partners or our amazing Senior Tax Professionals to determine if we are a good fit for each other, and how an engagement with our team looks. Tax returns only? Business advisory? Tax strategy and planning? Rental property support?
