What You Get With Accountably For S Corps

End to End S Corp Workflow, From Trial Balance To Filed Return

We scope the engagement, align to your 1120 S standards, and deploy a trained offshore pod that works like your in house team. The pod manages data intake, trial balance import, book to tax mapping, permanent file updates, and workpaper prep, then routes the file through our multi layer review. Schedule K 1s are prepared with basis awareness and separately stated items mapped correctly, then we align final e file packaging to your process. Our teams are trained on U.S. S Corp conventions, documentation logic, and deadline accountability, so review feedback sticks and revision cycles shrink.

Built For Your Busy Season

Capacity plans are set against utilization, not guesswork. We allocate by filing group, state footprint, and entity complexity, then load level across the pod. If a team member is out, continuity plans keep the work moving, and escalation rules bring in technical reviewers early if a position, basis, or SALT issue could impact the date. You see live status, blockers, and aging, so you can manage client promises with confidence.

Compliance You Can Defend

• Filing deadlines, we work to the 15th day of the third month after year end, for calendar year filers in the 2024 tax year the due date fell on Monday, March 17, 2025, since March 15 was a Saturday, with six months available on a timely filed Form 7004. (irs.gov)
• Reasonable compensation, we help you document roles, time, and market indicators so shareholder employees are paid wages that match their duties, and we flag issues that risk reclassification. (irs.gov)
• Two percent shareholder health insurance, we set the W 2 treatment correctly, included in Box 1 for income tax withholding and excluded from Social Security and Medicare when the plan meets IRS conditions, and we note the above the line deduction rules. (irs.gov)
• Basis tracking, we maintain shareholder schedules and update Form 7203 data points to prevent loss disallowance and basis surprises later in the personal returns. (irs.gov)
• Extensions, when needed, we prepare the estimate and file Form 7004 on time, electronic where supported, and align your calendar to the extended six month window. (irs.gov)

Why Firms Struggle To Scale S Corp Work, And How We Fix It

The Real Bottlenecks

What slows your firm is not sales. It is production that drags reviews, unstructured workpapers that force rework, hiring delays that leave gaps, and a lack of visibility that lets issues surface too late. When teams push to meet dates, documentation suffers, and every future review takes longer. Advisory gets deferred because everyone is stuck in compliance. You feel it when partners spend nights in K 1 reviews instead of client meetings.

Our Answer, Delivery Architecture

Accountably removes execution chaos with SOP driven workflows, standardized naming, and version control. We run a preparer, senior, quality, final review sequence with internal checklists that catch common misses before your reviewer opens the file. Turnaround SLAs keep dates predictable, progress reporting gives you live visibility, and escalation paths get tough issues in front of the right expert early. You retain your process, your templates, and your systems. We bring the discipline, the team, and the capacity.

• Trial balance, import from QuickBooks or CSV, tie to the year end balance sheet, and prepare book to tax adjustments.
• Workpapers, standardized binders, naming, and version control, tick marks that match your firm’s conventions, and permanent file updates for equity and debt.
• Return prep, draft 1120 S, map separately stated items, prepare each K 1, and run diagnostics.

• E file package, your reviewer signs off, we assemble the return, apply e file schemas, and stage for submission with state returns added as scoped.

The Wow, Where Your Team Feels The Difference

• Visibility, live progress boards and blockers let your managers course correct mid week, not the night before a deadline.

• Advisory unlock, when compliance flows, partners have time for client strategy, pricing, and cross state planning.

Compliance Details That Matter

Deadlines, Extensions, And Weekend Rule

For calendar year S corporations, the return is due the 15th day of the third month after year end. In the 2024 tax year this date fell on Monday, March 17, 2025, since March 15 was a Saturday. If you need more time, a timely and properly completed Form 7004 generally provides a six month extension. We prepare the estimate, file the form by the original due date, and track acknowledgments. (irs.gov)

Reasonable Compensation, Document Before You File

The IRS expects shareholder employees who provide more than minor services to receive wages that fit their duties. Courts have upheld reclassification when wages are too low and distributions are substituted for payroll. We help you document duties, time, comparable pay, and bonus policy, then align W 2s before we finalize K 1s. (irs.gov)

Two Percent Shareholder Health Insurance

Premiums paid for greater than 2 percent shareholders are deductible by the S corporation and must be reported as wages on the W 2 for income tax withholding, generally excluded from Social Security and Medicare when the plan covers a class of employees. We set up the treatment in payroll reports and add clear notes in the workpapers, which keeps the W 2, K 1, and shareholder 1040 in sync. (irs.gov)

Basis, At Risk, And Form 7203

Losses and deductions are limited by stock and debt basis. We track beginning basis, contributions, income increases, distributions, nondeductible expenses, and debt changes in a schedule mapped to Form 7203, so suspended losses carry correctly and next year’s work starts clean. (irs.gov)

Filing Logistics

We align your e file timing by state, include required statements, and produce final client deliverables the way your firm prefers, paper ready or portal ready. Our quality reviewer signs off that totals tie and that the K 1s match the e filed return, so no one is chasing mismatches later.

Sample Steps And Compliance Focus

FAQs

What is the S Corp filing deadline for calendar year returns?

Form 1120 S is due the 15th day of the third month after year end. For the 2024 tax year it fell on Monday, March 17, 2025, since March 15 was a Saturday. File Form 7004 by the original due date to extend six months if needed. (irs.gov)

When should I file Form 7004 for an S Corp?

File by the original due date of the return. A timely and accurate Form 7004 generally provides a 6 month extension to file. We handle the estimate, e filing where supported, and confirmation tracking. (irs.gov)

How do you handle shareholder basis and Form 7203?

We maintain basis schedules during prep, update beginning balances, record income, distributions, and nondeductible items, then map to Form 7203 so losses are limited correctly and carryforwards are tracked. (irs.gov)

What is the 2 percent shareholder health insurance rule?

Premiums for greater than 2 percent shareholders are included in W 2 wages for income tax withholding, usually excluded from Social Security and Medicare when the plan covers a class of employees, and can be deductible above the line by the shareholder when conditions are met. (irs.gov)

How do you help with reasonable compensation?

We document duties, time, comparable pay, and policy so wages fit the facts. The IRS can reclassify distributions if wages are unreasonably low, so we align payroll before finalizing K 1s. (irs.gov)

Both. We support tax compliance, advisory planning for owners, CAS and controller routines, and audit PBC and tie outs under your leadership. The goal is to free partner time and raise quality across the board.
