Business Tax

Tax returns that get modeled, not just filed

Business tax preparation for Indiana S-corps, partnerships, LLCs, and schedule-C filers — modeled before filed, so April holds no surprises.

Business tax preparation for Indiana S-corps and LLCs — federal and Indiana returns being reviewed

When should an Indiana business start preparing for tax filing?

October. The work that actually saves money — entity-level elections, retirement plan funding, bonus depreciation decisions, owner-comp adjustments — happens before December 31. By the time it's April, the year is locked. Our existing clients get a Q4 planning call by default.

If you're new to us mid-year: we can still extend and plan the back-half of the current year while looking at the prior year for amendments where worth it.

Do you file federal extensions automatically?

Yes — every business return gets a federal and Indiana extension filed by the original deadline (March 17 for S-corp/partnership, April 15 for sole prop). Extensions are filing-only; tax owed is still due by the original date, so the planning call in Q4 matters.

How do you handle multi-state returns?

Indiana has reciprocity agreements with five states (KY, MI, OH, PA, WI) for individual wages but not for business returns. For Indiana businesses with sales or employees in surrounding states, we file the necessary nonresident or apportioned business returns and coordinate the Indiana credit for taxes paid elsewhere.

What does a business return cost in Fort Wayne?

Federal + Indiana S-corp or partnership: typically $1,200–$3,500 depending on complexity (single state, owner count, balance-sheet complexity). Schedule-C sole prop with Schedule SE: $500–$1,200. Multi-state, multi-entity, or first-year cleanup adds to it. We quote flat fees after a scoping call.

What's included

  • Federal return. Form 1120-S, 1065, or schedule C — with K-1s issued to owners by mid-March.
  • Indiana return. IT-20S, IT-65, or pass-through on owner's IT-40. Composite returns for nonresident owners.
  • Multi-state. Reciprocity, nexus, and apportionment for Indiana businesses with employees or sales in surrounding states.
  • Year-end planning call. Q4 call to lock in moves before December — bonus depreciation, retirement contributions, owner comp.
  • Owner Form 1040. Personal returns included for owners (see Business Owner Income Tax service).

Common questions

Business Tax Preparation — questions we get

Can you take over my return mid-year if I'm unhappy with my current preparer?
Yes — we onboard mid-year regularly. We need prior-year returns, current-year books, and a signed engagement letter. Most onboarding takes one scoping call.
Do you handle amended returns?
Yes — federal 1120-X / 1065-X and Indiana amended returns. We'll first verify the amendment is worth the cost and statute-of-limitations math.
Do you file the Indiana Business Personal Property return?
Yes — IT-103 (or the under-$80k exemption affidavit) filed annually with the county assessor for clients with depreciable business assets.
What if my business has crypto / DeFi activity?
We handle crypto reporting on business and personal returns. For complex high-volume activity, we may recommend a specialty tool.
Do you e-file?
Yes — federal and Indiana e-filed by default unless paper-only forms are required (rare).
Will you represent me if the IRS audits the return you filed?
Yes — see IRS Representation. Returns we prepare are defended without extra retainer for routine notices.
