Serving US clients from Pakistan: the taxes, the calendar, the forms, and what the ledger can produce

An accountant in Lahore or Karachi who keeps books to IFRS and files with the FBR already knows most of what a US small business needs: a ledger, a payroll, a tax on sales, a tax on profit, and a calendar. What differs is which agency wants what, on which form, through which pipe, and who is allowed to push it through. This chapter is the map: the taxes and their frequency, how each return is transmitted, what a preparer outside the United States may do in their own name, whether QuickBooks actually files anything with the IRS, and which of it all SQL-Ledger can generate today or after the earlier chapters.

2026-08-26 · dates are for tax year 2026, filed in 2027; IRS pages are the primary sources unless the text says otherwise. This is a map, not tax advice.

7.1Three things to unlearn first

First, there is no single tax authority. The IRS takes income tax, self-employment tax, payroll withholding and the information returns; each state takes its own income tax, sales tax and unemployment insurance through its own portal, on its own calendar; and there is no federal sales tax or VAT at all. Second, the entity type decides the form, not the size of the business: a one-person company can be a sole proprietorship, a single-member LLC, an S corporation or a C corporation, and each files something different. Third, “filing” is not uploading a PDF: federal returns travel as XML through the IRS’s Modernized e-File system, and only an Authorized IRS e-file Provider may transmit. Who may be one is the subject of section 7.5, and it is the section that matters most to a reader in Pakistan.

7.2The taxes, by entity type

aSole proprietor and single-member LLC

The company does not file; the owner does. Business profit goes on Schedule C of the owner’s Form 1040, and Schedule SE computes self-employment tax — 15.3% (12.4% Social Security plus 2.9% Medicare) on 92.35% of net profit, the Social Security part capped at the 2026 wage base of $184,500, half of it deductible. Due 15 April 2027; Form 4868 extends filing, not payment, to 15 October.

Because nothing is withheld, tax is paid in advance through Form 1040-ES in four instalments: 15 April, 15 June and 15 September 2026 and 15 January 2027. The IRS safe harbour: pay in at least 90% of this year’s tax or 100% of last year’s (110% if last year’s income exceeded $150,000), or expect to owe under $1,000, and there is no penalty. Payment is by IRS Direct Pay or EFTPS, not with the return.

bPartnership and multi-member LLC

Form 1065, an information return: the partnership pays nothing, each partner receives a Schedule K-1 and pays on their own 1040. Due 15 March 2027; Form 7004 extends six months. Partners pay estimates as in (a).

cS corporation

The one most single-owner firms with real profit choose. Form 1120-S with K-1s, due 15 March 2027, extended by Form 7004. The corporation pays no federal income tax; profit flows to the owner’s 1040 without self-employment tax — which is why the IRS insists the working owner first draws a reasonable W-2 salary, with the payroll obligations of section 7.3 that follow. The election itself is Form 2553, filed by mail or fax within two months and fifteen days of the start of the year it is to take effect (Rev. Proc. 2013-30 forgives late ones).

dC corporation

Form 1120, due 15 April 2027, flat 21%, extended by Form 7004. Corporate estimates fall on 15 April, June, September and December, and must be paid electronically. Dividends are taxed again in the owner’s hands; small firms rarely choose this unless investors do.

7.3Employer obligations, the moment there is a payroll

An S corporation owner is an employee of their own company, so this section applies to most one-person firms that have chosen that form.

  • Deposits. Withheld income tax and both halves of Social Security and Medicare are deposited electronically through EFTPS on a monthly schedule (by the 15th of the next month) if the lookback-year liability was $50,000 or less, otherwise semi-weekly. A liability of $100,000 in one day is due the next business day.
  • Form 941 reconciles the quarter: wages, withholding, both halves of FICA, deposits made. Due the last day of the month after the quarter. The IRS may instead assign Form 944, annual, to employers whose liability is $1,000 or less — but only if it writes to say so.
  • Form 940 is the annual federal unemployment return: 6.0% on the first $7,000 per employee, reduced to 0.6% by the credit for state unemployment tax paid; deposited quarterly once $500 accumulates.
  • W-2 and W-3 go to the Social Security Administration by 1 February through its free Business Services Online, and copies to each employee.
  • The state wants its own withholding registration and returns, and an unemployment-insurance account with a rate it assigns. Every state is different; this is the part a preparer must learn one state at a time.

7.4Information returns, sales tax, and the rest

a1099s

A business that pays a contractor $2,000 or more in 2026 — the threshold the One Big Beautiful Bill Act raised from $600, indexed from 2027; reported by practitioners, not yet on an IRS page we could find — sends Form 1099-NEC to the contractor and the IRS by 1 February 2027. Rent, royalties and some other payments go on 1099-MISC. Before paying anyone, collect a Form W-9 for their taxpayer number. A payer with ten or more information returns of all kinds, W-2s included, must file electronically; from 1 January 2027 the only IRS channel is IRIS — the old FIRE system closes on 19 November 2026 — either its free web portal (keyed, or CSV of up to a hundred returns) or its XML API. Both need a Transmitter Control Code, applied for through IRS e-Services with identity verification, which can take forty-five days. Card processors and marketplaces send the business a 1099-K only above $20,000 and 200 transactions, the threshold restored in 2025.

bSales tax

Not federal. A business registers in each state where it has nexus — a physical presence, or economic presence above the state’s threshold ($100,000 of sales in most; $500,000 in California, New York and Texas; none in Delaware, Montana, New Hampshire, Oregon). The state assigns a filing frequency, monthly (usually due the 20th), quarterly or annual, by expected volume. Every sales-tax state now has a marketplace-facilitator law, so Amazon, Etsy and eBay collect and remit on their own sales, and the business reports them as facilitator-collected. Returns are filed on the state’s portal; there is no federal pipe.

cOccasionally

  • State franchise tax or annual report: Delaware LLCs $300 by 1 June; California LLCs $800 a year plus a fee above $250,000 of California income; Texas franchise report even when no tax is due.
  • Form 8300 within fifteen days of receiving more than $10,000 in cash.
  • Form 720 excise, Form 2290 heavy vehicles — only for those businesses.
  • FinCEN beneficial ownership: gone for US-formed companies. Domestic entities were exempted in March 2025 and the exemption was made permanent by the final rule effective 14 August 2026. Only foreign entities registered in a state still report.

7.5How a return actually reaches the IRS, and who may send it

This is the section to read twice.

ReturnFormatPipeWho may transmit
1040, 1065, 1120-S, 1120, 4868, 7004MeF XMLModernized e-FileAn Authorized IRS e-file Provider holding an EFIN; the taxpayer through consumer software (the vendor is the provider); or paper, still legal for the taxpayer. A preparer expecting to file eleven or more 1040s in a year must e-file.

Plate 7.2 · What a preparer resident in Pakistan may hold, and may not
CredentialOpen to a non-resident, non-citizen?Detail
PTIN — required to prepare any US return for payyes$18.75 a year. Without an SSN: Form W-12 with Form 8946 and notarised passport copies, a non-US address, about six weeks by post.
EFIN — required to transmit through MeFnoIRM 3.42.10: every Principal and Responsible Official must be a US citizen or lawful permanent resident with an SSN or ITIN, fingerprinted or credentialed. The “foreign EFIN” route exists only for a firm inside the business group of an existing US provider, which stays answerable.
Enrolled Agent — unlimited representation rightsyesPTIN, the three-part Special Enrollment Examination within three years, Form 23 ($140), a tax-compliance check. No citizenship or residency test appears anywhere in the IRS rules. From 2026 the exam vendor is PSI; international candidates sit it by remote proctor, scheduling for which the IRS FAQ calls “temporarily delayed” as of this writing.
Form 2848 / 8821 — speak to the IRS for a clientpartly2848 power of attorney needs a credentialed representative — an EA qualifies; 8821 information authorisation is open to anyone.
State registrationsvariesNew York registers preparers “within and outside” the state ($100 at ten returns); Oregon licenses anyone preparing Oregon returns; Maryland registers; California’s CTEC applies only to preparers inside California.

aThe three working models

  1. Prepare here, transmit there. The Pakistani firm keeps the books, prepares the return and the workpapers; a US CPA or EA firm with an EFIN reviews, signs and transmits. This is the model the IRS anticipates: the outsourcing rules under §7216 require the client’s written consent before return information leaves the United States, and if an SSN travels the consent must say so in an underlined sentence, confirm that both firms keep an adequate data-protection framework, and warn that US privacy law may not reach abroad (Rev. Proc. 2013-14). Penalties for skipping this are criminal.
  2. Prepare here, the client files. For the smallest clients, the preparer produces the figures and the client keys them into consumer software or self-files 941s with their own 94x PIN. Legal, cheap, and the reason a clean set of reports matters more than a filing pipe.
  3. Become the credential. A Pakistan-resident EA holds representation rights and a PTIN, signs as preparer, and still transmits through a US ERO or the client. The EA credential is what turns a bookkeeping service into a tax practice in the client’s eyes.

What none of the three allows is the thing prospects assume: the offshore firm filing federal returns directly under its own name. That requires an EFIN, and an EFIN requires a US person.

7.6Does QuickBooks talk to the IRS?

Less than its marketing implies, and only through the same pipes as anyone else.

  • Payroll: yes. QuickBooks Online Payroll, at every tier, calculates, deposits and files 941, 940, W-2 and the state forms as a Reporting Agent — the employer signs Form 8655 and Intuit transmits under its own EFIN and PIN. The employer still has to obtain its own state withholding and unemployment accounts. Elite adds a penalty guarantee of up to $25,000 a year.
  • 1099s: yes, as a vendor. Intuit’s 1099 e-file service transmits NEC and MISC and mails contractor copies, included with Contractor Payments and payroll or priced per form otherwise. It is an IRIS transmitter like any other vendor.
  • Income tax returns: no. QuickBooks does not file a 1040, 1065, 1120-S or 1120. The paths are TurboTax (including its assisted “Live” and “Full Service Business” offers, which cover Schedule C, 1065 and 1120-S but not Form 1120), or for accountants an export from QuickBooks Online Accountant’s Prep for Taxes into ProConnect Tax. Those are separate products with their own fees, and ProConnect’s transmission still needs the accountant’s EFIN.
  • Sales tax: no. Automated Sales Tax computes the rate and prints a liability report. Intuit’s own help page says it “does not file or remit returns automatically at any subscription level”; the business files on the state portal, or pays Avalara, TaxJar or a similar service.
  • Estimated tax: computed, not paid. Solopreneur works out the quarterly figure; payment is by Direct Pay or EFTPS.
Finding

Of the whole federal calendar, QuickBooks transmits exactly two things itself: payroll returns, as a reporting agent, and 1099s, as an IRIS vendor. Everything else — the income tax return, the sales tax return, the estimates — is a report handed to a separate filer. That is the standard any competitor is held to, and it is a standard of reports, not of pipes.

7.7What SQL-Ledger can produce, today and after the book

Every filing in this chapter is, at bottom, a handful of totals from the ledger arranged on a form. The table separates what is a report from what is a pipe, and marks where our ledger stands.

FilingWhat the ledger must supplyOursWhere it stands
Schedule CIncome and each expense category on the Schedule C lines; home office, vehicle and depreciation as memorandapartialThe income statement gives the totals; the three US charts (General, Service, Manufacturing) are not mapped to Schedule C line numbers. See enhancement 1.

Enhancement 1 maps the lines; the rest stays in the tax software, as it does with QuickBooks.
1120As above, corporatepartialSame.
941, 940, 944, depositsWages, withholding, FICA by employee and by deposit periodpartialHR → Payroll posts pay with user-defined wage and deduction tables and prints payslips; a preparer can build the 2026 federal and one state’s tables by hand. There is no 941 layout, no deposit-schedule report, and the tables are not date-effective (backlog item 50). Enhancement 2.
W-2, W-3Annual wages and withholding per employeepartialThe payroll transactions report gives the totals per employee; an EFW2 or W-2 CSV for SSA Business Services Online is enhancement 2.
1099-NEC, 1099-MISCPayments per vendor per calendar year, by box, with TINbuildChapter 1 item 11 adds the vendor tax flag, TIN and totals. Add the IRIS CSV layout and it is a self-service filing under a client’s own TCC.
Sales tax returnsTaxable, exempt and facilitator-collected sales and tax by jurisdiction for the state’s periodpartialTax accounts per jurisdiction with Tax Collected and Non-taxable reports; chapter 1 item 11 makes them one period return. A marketplace-collected flag on the invoice is the missing column.

State franchise and annual reportsRevenue and the balance sheethaveReports exist; the forms are the state’s.
Transmission of any federal returnskipNot a ledger’s job, and for us not possible: transmission needs an EFIN or a TCC held by a US person or by the client. QuickBooks is in the same position for every return but payroll.

7.8The four enhancements

Tier 1Form-line mapping: 1
Tier 2Payroll to the forms: 2
Tier 3Estimates: 3
Tier 4The practice: 4

1Tax-form lines on the chart, and a Tax Summary report

SQL-Ledger already has the mechanism: GIFI codes, the Canadian form-line identifiers that sit on each account and roll up on the statements. Generalise the field into a form line with a form name, ship a mapping file per US form — Schedule C lines 1 to 27, 1120-S page 1 and Schedule L, 1065 page 1 and Schedule L, 1120 — and pre-assign it on the three US charts at dataset creation. A Tax Summary report under Reports prints the chosen form’s lines with the year’s totals, a memo section for the items that are not ledger balances (home office square footage, vehicle miles, meals at 50%), and the book-to-tax adjustments the preparer keys in, saved per year. Export as CSV in the column order the professional tax packages import. This is the “Prep for Taxes” export QuickBooks Online Accountant offers, without the ProConnect lock-in, and it is the report a Pakistani practice hands to its US signing partner.

Touches: SL/AM.pm chart screens, SL/RP.pm, the three US chart files, one schema upgrade. Effort: medium.

2Payroll tables with dates, and the 941, 940 and W-2 layouts

Make the wage and deduction tables date-effective, and ship the 2026 federal tables — withholding by the Publication 15-T percentage method, Social Security to the wage base, Medicare and the additional Medicare, FUTA to the $7,000 base — with a state table format the preparer fills for each state the practice serves. Then three reports: a 941 worksheet per quarter with lines 1 to 15 and the monthly or semi-weekly deposit schedule beneath it; a 940 worksheet for the year; and W-2 data per employee, printed and exported in the SSA’s EFW2 record layout so the client can upload it to Business Services Online themselves. The transmission of the 941 remains with the client’s 94x PIN or the US reporting agent; the worksheet is what they key.

Touches: SL/HR.pm, bin/mozilla/hr.pl, table seed files, one schema upgrade. Effort: medium-large; the backlog’s item 50 in another form.

3Estimated-tax worksheet and vouchers

A small screen: the year-to-date profit from the ledger, last year’s tax and adjusted gross income keyed once, the safe-harbour rule applied, and the four instalments computed and printed on 1040-ES voucher layouts with the dates. Also a pass-through variant that reads the profit at the entity and splits it by owner percentage. Nothing here is hard; it is the question a one-person client asks every quarter, and answering it from the ledger rather than a spreadsheet is what keeps them.

Touches: SL/RP.pm, one template. Effort: small.

4The practice layer on the panel

Not a ledger feature but the thing that makes the first three sellable from Pakistan. On the Ledger123 panel: a practice account that owns many client datasets; a per-client compliance calendar generated from the entity type, the states, and whether there is payroll, with the dates in Plate 7.1 and each state’s sales-tax frequency, ticked off as each return’s report is produced; a §7216 consent template with the required underlined language, signed by the client before the dataset is opened to the practice; and a signing-partner role for the US firm that transmits, with read access to the Tax Summary and the worksheets of enhancements 1 to 3 and nothing else. That role is the accountant seat of chapter 1 item 8 with a scope.

Touches: the panel, SL/Members.pm, the roles of chapter 2. Effort: medium.

7.9What we will not build

A transmitter. Becoming an IRS software developer and transmitter means MeF schema conformance, assurance testing every year, and an EFIN held by a US person. It is a product in itself and it is the wrong product: the market already has cheap 941 and 1099 e-file vendors that take a CSV, and the income-tax return belongs in the signing firm’s software. We produce the numbers in the layouts those tools import.

Sales-tax filing. Fifty portals. The period return of chapter 1 item 11 produces the figures; Avalara or TaxJar file them for those who want that.

In one sentence

A Pakistani accountant can hold a PTIN and become an Enrolled Agent but cannot hold an EFIN; QuickBooks files only payroll and 1099s itself; so the winning service is immaculate reports in the form’s own line order, a compliance calendar, a signed consent, and a US partner who presses send — and four enhancements give SQL-Ledger exactly that.
